[00:24:36] <PetefromTn_> It's kinda deaaad in here today
[00:24:49] <CaptHindsight> _methods: I always hear about how the castings of HF tools tend to break catastrophically
[00:25:50] <CaptHindsight> the sheet metal brakes sometimes go with a bang
[00:26:34] <_methods> i was barely crankin on it and it broke
[00:26:57] <CaptHindsight> _methods: did any pieces fly off? or did it just snap?
[00:27:00] -!- Loetmichel2 [Loetmichel2!~cylly@p54B1041B.dip0.t-ipconnect.de] has joined #linuxcnc
[00:27:08] <_methods> i just kinda broke
[00:27:15] <_methods> really anticlimactic lol
[00:27:42] <CaptHindsight> I looked through 3 boxes of shop presses to find the one I took home
[00:27:54] <_methods> i was babying it at first
[00:27:54] <CaptHindsight> this was the only one with good welds
[00:27:59] <_methods> it kept bogging down
[00:28:16] <_methods> but then i figured i'd see how far i could push it........that didnt get me far lol
[00:28:29] <CaptHindsight> then I drag it back and find out that the return springs won't fit since the spacing was too tight :)
[00:28:30] -!- Loetmichel has quit [Ping timeout: 248 seconds]
[00:28:52] <CaptHindsight> good welds but it the wrong spots
[00:28:56] <_methods> the hyraulic press?
[00:29:02] <CaptHindsight> yeah
[00:29:02] <_methods> or the press brake they sell?
[00:29:06] <_methods> ah yeah
[00:29:21] <CaptHindsight> 40 ton hydraulic
[00:29:36] <_methods> it's definitely hit or miss
[00:29:39] <_methods> mostly miss lol
[00:29:44] <CaptHindsight> yeah
[00:29:56] <CaptHindsight> i buy the cheap batteries for my calipers there
[00:30:04] <CaptHindsight> 10-20 for $2
[00:30:11] <_methods> oh wow
[00:30:15] <_methods> yeahthat's super cheap
[00:30:50] <PetefromTn_> I bought my little vacuum pump there and it works pretty decent
[00:31:01] <_methods> their shitty cup guns aren't too bad
[00:31:09] <_methods> as long as you keep them really clean
[00:31:18] <CaptHindsight> I've only gotten lucky with a compound miter saw but I got a blade that cost more than the saw for cutting extrusions
[00:31:20] <PetefromTn_> but EVERY other electric hand power tool I ever bought there was a BIG STINKING PILE OF DOG DUNG!!
[00:31:36] <PetefromTn_> _methods It's funny you say that
[00:31:39] <_methods> i haven't bought too many electric tools from them
[00:31:47] <PetefromTn_> I have a couple name brand pro spray guns
[00:31:51] <CaptHindsight> I borrowed a band saw from HF
[00:32:00] <CaptHindsight> lasted 3 hours
[00:32:07] <PetefromTn_> and I bought a cheap pro model standard cup paint gun from HR
[00:32:09] <PetefromTn_> HR
[00:32:11] <PetefromTn_> HF
[00:32:12] <PetefromTn_> LOL
[00:32:17] <_methods> hah i bought that $200 horizontal band saw
[00:32:24] <_methods> i've been very happy with it so far
[00:32:28] <PetefromTn_> and it is probably the best most durable paint gun I ever used
[00:32:41] <_methods> yeah their cup guns are actually not horrible
[00:32:47] <_methods> but you do have to keep them clean
[00:32:49] <PetefromTn_> my 7x12 bandsaw I think is a HF model and it kicks ass
[00:33:04] <_methods> yeah i got the little 4x7 saw
[00:33:13] <PetefromTn_> I bought an air brush from there twice and both sucked
[00:33:15] <CaptHindsight> 1/8" short TI coated double end drill bits
[00:33:37] <PetefromTn_> now I got a quality pair and I am much happier LOL
[00:33:40] <_methods> you bought drill bits there?
[00:33:42] <CaptHindsight> I use them for SS since they are so short and are 10 for $5
[00:33:48] <_methods> hmmm
[00:33:52] <CaptHindsight> those are the only ones :)
[00:33:57] <_methods> ive never even given their bits a 2nd look
[00:34:02] <PetefromTn_> 10 minutes to fresh baked cookies!!
[00:34:06] <_methods> i figured they were made out of alum or something lol
[00:34:23] <PetefromTn_> I started my machining hobby with one of their drill sets
[00:34:26] <CaptHindsight> I chuck these so only 1/4" sticks out
[00:34:36] <PetefromTn_> and I just replaced the ones I munched with quality ones as i went along
[00:34:42] <CaptHindsight> good for poking holes in sheet for fasteners
[00:35:15] <PetefromTn_> https://knoxville.craigslist.org/tls/5123236656.html Hmmm
[00:36:19] <zeeshan> jeez that is expensive for that tool box!
[00:36:31] <PetefromTn_> it comes with all the tools
[00:36:43] <zeeshan> still looks expensive for what it comes with
[00:37:03] <_methods> wow
[00:37:05] <_methods> good deal
[00:37:22] <_methods> jo blocks, pin gages, height gages
[00:37:24] <_methods> score
[00:37:41] <PetefromTn_> yeah and indicators galore and boring heads, angle gauges
[00:38:20] * zeeshan doesn't know anything
[00:38:25] * zeeshan only buys a tool box once a month
[00:38:27] <zeeshan> :D
[00:38:34] <malcom2073> I hope my work starts auctioning all the crap they are trying to get rid of
[00:38:44] <malcom2073> we have a set of kennedy rollarounds
[00:38:46] <_methods> big money in that box
[00:38:54] <PetefromTn_> I wouldn't pay $2k for it but I don't think it is a terrible deal really
[00:38:59] <zeeshan> that box here would go for 550
[00:39:03] <zeeshan> w/ all those tools
[00:39:11] <_methods> well the bottom and top box is what $800
[00:39:11] <zeeshan> maybe stuff is expensive in Tn?
[00:39:13] <_methods> by itself
[00:39:21] <PetefromTn_> it really depends on the name brands of the tools inside it
[00:39:32] <_methods> no just the kennedy boxes
[00:39:34] <malcom2073> I need to put my lathe up on craigslist
[00:39:42] -!- patrickarlt has quit [Ping timeout: 248 seconds]
[00:39:57] <PetefromTn_> what kinda lathe?
[00:40:06] <malcom2073> 30's southbend 9c
[00:40:28] <tiwake> how much?
[00:40:34] <malcom2073> Still trying to figure that out
[00:40:42] <PetefromTn_> where is ya?
[00:40:47] <malcom2073> South central PA (york pa)
[00:40:57] <zeeshan> the bottom cabinet is a kennedy 277b
[00:41:02] <zeeshan> retail is 750 usd for that
[00:41:26] <malcom2073> It's decent, the ways have a bit of wear on them but very minimal so couldn't consider it perfect. Has a bunch of tooling though, steadyrest, live/dead centers,
[00:41:45] <zeeshan> the top looks like a model 520
[00:41:50] <zeeshan> $300~ usd retail
[00:41:58] <_methods> those things go for decent money to hobbiest crowd
[00:42:13] <_methods> its easier to sell those little lathes i think sometimes
[00:42:19] <malcom2073> Yeah, it's a two man lift
[00:42:21] <malcom2073> Which is nice
[00:42:49] <_methods> well i saw an atlas go for $1500 the other day
[00:43:36] <malcom2073> That's what I'm thinking, maybe asking $1500-%2k
[00:43:45] <malcom2073> has a three and four jaw chuck too
[00:43:46] <PetefromTn_> I wouldn't mind having a nice little vintage lathe to mess with as a second lathe in the shop
[00:43:52] <malcom2073> Really the big seller is it's all tooled up
[00:43:56] <zeeshan> http://www.kijiji.ca/v-tool-storage-bench/city-of-toronto/kennedy-tool-box-stack-4-boxes-including-roller/1077898014?enableSearchNavigationFlag=true
[00:44:19] <_methods> well i'd start at $2k
[00:44:27] <_methods> that way you got wiggle room
[00:44:45] <malcom2073> Think having a link to a youtube video of it cutting wouldbe beneficial? Or no real effect?
[00:44:46] <CaptHindsight> http://www.harborfreight.com/media/catalog/product/cache/1/image/9df78eab33525d08d6e5fb8d27136e95/i/m/image_23124.jpg
[00:44:53] <_methods> i picked my atlas 10f up for $500
[00:44:57] <PetefromTn_> you really think it is worth $2k? not bagging on it just asking
[00:44:58] <_methods> but i got lucky
[00:45:05] <malcom2073> PetefromTn_: I really have no idea
[00:45:08] <CaptHindsight> http://www.harborfreight.com/quickview/index/index/id/1800/
[00:45:12] <malcom2073> I've seen lathes of similar sizes go for ALL sorts of prices
[00:45:14] <_methods> yeah they can go for $2k easy because of the old man thing
[00:45:18] <malcom2073> Yeah
[00:45:20] <_methods> old man tinkering in garage
[00:45:27] <_methods> they love those things
[00:45:30] <malcom2073> You get a guy in his 70's who used to use one back in the day, wants something small and familiar
[00:45:33] <PetefromTn_> I mean if it is REALLY REALLY NICE and clean probably
[00:45:46] <malcom2073> The other thing, it's a southbend, people are weird about the name for some reason.
[00:45:46] <PetefromTn_> Cookies are done cooking ;)
[00:45:57] <malcom2073> I got a grizzly 12x37, that is apparently worth less
[00:46:20] <PetefromTn_> I really like that 12x37 is it the belt drive one?
[00:46:26] <malcom2073> Yeah
[00:46:28] <malcom2073> 9242 or something?
[00:46:34] <PetefromTn_> Those are great little lathes I think
[00:46:41] <_methods> i just scored the dumore toolpost grinder for my atlas at last auction i went to for $50
[00:46:41] <malcom2073> Little heh
[00:46:49] <_methods> so now it has every attachment
[00:46:57] <PetefromTn_> _methods jeez man you and the auctions are gonna kill me
[00:47:02] <_methods> hahah
[00:47:02] <malcom2073> Got it for $250, BARELY used
[00:47:03] <_methods> yeah man
[00:47:31] <_methods> i'm always watching the auctions
[00:47:33] <PetefromTn_> I would love to find another cheap 12x36 lathe like I sold I sure miss it
[00:47:36] <malcom2073> Plus both steady rests, both chucks, tooling, and a manual mill rotary axis which was for some reason grouped in it
[00:47:45] <malcom2073> I love auctions
[00:47:48] <zeeshan> doesn't paying the buyers premium making auctions expensive?
[00:47:48] <_methods> im always on the lookout for my 10ee
[00:47:49] <malcom2073> especially local,badly advertized ones
[00:47:52] <_methods> one day ill find her
[00:47:55] <malcom2073> _methods: My dad has a 10ee... :)
[00:48:02] <malcom2073> He wants good money for it though
[00:48:07] <_methods> lalalallalalallaalla i don't want to hear it
[00:48:17] <_methods> yeah they go for big money
[00:48:19] <malcom2073> I'll call you in 40 years when he dies and I have to auction it off haha
[00:48:23] <_methods> heheh
[00:48:38] <_methods> im lookin for a cincinnati #1 horizontal now
[00:48:50] <malcom2073> ohhh
[00:48:52] <malcom2073> wait one
[00:49:02] <_methods> i just missed one 2 auctions back
[00:49:11] <_methods> i chickened out at $600
[00:49:21] <_methods> i think someone got it for like $800
[00:49:41] <malcom2073> Nice
[00:49:52] <_methods> theres a steinel in jacksonville i've been lookin at
[00:49:56] <malcom2073> http://paradiseequipment.com/communities/1/000/001/517/391//images/10160710.jpg
[00:49:59] <malcom2073> That's up at auction friday
[00:50:01] <_methods> but i' don't want to pay $1800
[00:50:03] <malcom2073> prolly go for less than $500
[00:50:13] <_methods> yeah thats too big
[00:50:19] <_methods> looks like a #2
[00:50:21] <malcom2073> Nonsense
[00:50:28] <malcom2073> http://paradiseequipment.com/communities/1/000/001/517/391//images/10160722.jpg
[00:50:30] <_methods> i'd love to have that
[00:51:17] <malcom2073> What's that last one?
[00:51:32] <_methods> i think its a #2 also
[00:51:49] <malcom2073> Wtf:
http://paradiseequipment.com/communities/1/000/001/517/391//images/10160702.jpg
[00:51:54] <malcom2073> Two spindles, one horizontal one vertical?
[00:52:23] <_methods> http://www.ebay.com/itm/Steinel-Horizontal-Milling-Machine-with-Jet-Rotary-Table-/201381217598
[00:52:27] <malcom2073> Anyway, each of those will go for either $2k+, or less than $500, depending on if there is anyone there *actually* interested in it
[00:52:34] <_methods> thats the one i've been dreaming about
[00:52:37] <PetefromTn_> jeez that is a MONSTER
[00:52:50] <malcom2073> They have these auctions every month
[00:52:55] <malcom2073> and every month they have a whole warehouse of HUGE machines
[00:52:57] <malcom2073> It's awesome
[00:53:06] <malcom2073> I should take my camera and just start documenting
[00:53:14] <_methods> but i don't see the overarm for that steinel
[00:53:15] <PetefromTn_> that gorton is awesome
[00:54:27] <_methods> yeah i'd love to have either
[00:54:45] <_methods> we got a #2 cinci vertical at work
[00:54:49] <_methods> that thing is a hawg
[00:55:05] <_methods> just way too big for my tiny garage
[00:55:06] <PetefromTn_> as I understand it they usually have BIG motors on them
[00:55:14] <PetefromTn_> 20-30 horse
[00:55:17] <_methods> oh man monsters
[00:55:31] <PetefromTn_> I probably couldn't run one here
[00:55:32] <malcom2073> Hah wow
[00:55:32] <_methods> look at the motor on the knee of that gorton
[00:55:48] <malcom2073> I'm sure that machine is deceptivly big
[00:55:52] <malcom2073> Pictures never do those machines justice
[00:56:06] <PetefromTn_> I once saw one of those big Cincinatti HV models in person...they are HUGE
[00:57:24] <_methods> http://www.ebay.com/itm/Cincinnati-No-3-Universal-Horizontal-Milling-Machine-25784-/252011390996?pt=LH_DefaultDomain_0&hash=item3aad0ca814
[00:57:29] <_methods> that's a cinci #3
[00:57:45] <malcom2073> Yeah they had one of those there a few months ago, massive
[00:57:55] <PetefromTn_> 10k lbs!!
[00:58:03] <_methods> thats pretty close to the same size of that gorton i bet
[00:58:25] <malcom2073> http://paradiseequipment.com/communities/1/000/001/517/391//images/10144863.jpg

[01:03:08] <zeeshan> they dont look like #40
[01:03:53] <malcom2073> Unknown
[01:03:59] <malcom2073> Mine is 30 iirc
[01:04:03] <malcom2073> so useless to me if so
[01:04:17] <malcom2073> 3-4 lots of different random holders

[01:05:19] <zeeshan> k&t
[01:05:19] <zeeshan> nice
[01:05:27] <PetefromTn_> now I could use that machine
[01:05:40] <malcom2073> PetefromTn_: Only 9 hours from you :-P
[01:05:55] <zeeshan> that table needs some evaporust!!
[01:05:58] <PetefromTn_> might as well be on pluto
[01:06:00] <zeeshan> (ps that stuff works GREAT)
[01:06:14] <malcom2073> zeeshan: I used evaporust on my ways, worked wonderful, they cleaned right up
[01:06:17] <zeeshan> pete you watching the pluto phone home?
[01:06:23] <zeeshan> on ustream
[01:06:28] <zeeshan> it starts in 24 min
[01:06:38] <zeeshan> malcom2073: its some sorcery
[01:06:39] <zeeshan> how it works
[01:06:46] <zeeshan> i had craters of rust on some of the tools i got
[01:06:50] <zeeshan> i thought i'd clean and sell em
[01:06:55] <zeeshan> but i kept em cause they turned out so well!
[01:07:05] <zeeshan> i had one scale that you couldnt even read the numbers
[01:07:12] <PetefromTn_> yeah its awesome...TOTALLY awesome
[01:07:36] <zeeshan> ive never owned real american/canadian made pipe wrenches before
[01:07:58] <zeeshan> boy they are of a different quality in comparison to the garbage from china

[01:13:55] <zeeshan> tig?
[01:14:22] <furrywolf> a miller 250A welder-generator, 2-cylinder Onan engine.
[01:15:18] <furrywolf> he said it has no spark, and he spent two weeks working on it and couldn't make it spark.
[01:15:35] <furrywolf> I don't see how you can be quite so incompetent, since I could rebuild the entire engine in substantially less than two weeks. lol
[01:17:37] <furrywolf> I'll poke at it after resting. made my back worse unloading it.

[01:17:48] <zeeshan> hmmm
[01:17:53] <malcom2073> I have an old onan generator, I like those motors
[01:18:09] <malcom2073> If it's an older one, the points system is probably gone, they're hell to keep running
[01:18:28] <furrywolf> define "gone".
[01:18:39] <malcom2073> Worn down
[01:18:42] <furrywolf> I've yet to find points that couldn't be fixed for under $5...
[01:18:45] <malcom2073> the "points" of the points eventually degrade
[01:18:59] <furrywolf> yeah, but I figure in two weeks he would have noticed that.
[01:19:08] <malcom2073> The rest of the components in my points box were rotted out, I need to ust replace it alltogether
[01:19:16] <furrywolf> first thing I'm going to check is the wiring, then I'll make sure the points are actually moving, and the little plunger isn't stuck.
[01:19:29] <malcom2073> Yeah
[01:19:54] <furrywolf> but first, rest. my back was way too crunched to do that.
[01:20:41] <furrywolf> I think the only locan onan dealer went out of business last year, so if it does need parts, I'll have to order online.
[01:20:43] <furrywolf> local
[01:20:58] <malcom2073> They're owned by a bigger motor company now
[01:21:00] <malcom2073> I forget who
[01:21:06] <furrywolf> Cummins
[01:21:21] <malcom2073> yeah
[01:21:25] <furrywolf> and it's the local cummins dealer that closed, and they were the only onan dealer too.
[01:21:54] <malcom2073> Damn
[01:22:21] <zeeshan> furrywolf: you got too many projects!
[01:22:23] <furrywolf> now, I heard this second-hand, I haven't verified it personally.
[01:22:28] <furrywolf> zeeshan: yes.
[01:22:34] <furrywolf> zeeshan: send me more money so they go quicker.
[01:22:45] <malcom2073> You may have more than me
[01:22:46] <zeeshan> my payment is only in excess tools!
[01:22:50] <malcom2073> to which, I tip my hat, and send my condolences

[01:23:15] <zeeshan> i think im gonna keep the caliper though
[01:23:18] <zeeshan> the mitutoyo
[01:23:26] <zeeshan> im really liking using it over digital
[01:23:43] <malcom2073> I like it because it makes me *think*
[01:23:45] <malcom2073> more than digital does
[01:23:47] <furrywolf> heh. someone stole my dial caliper.
[01:23:55] <zeeshan> theres no thinking involved man!
[01:23:57] <zeeshan> =D
[01:24:01] <malcom2073> Oh man I've been using DRO, and I had to do a normal mill today
[01:24:03] <malcom2073> It hurt my head
[01:24:10] <zeeshan> like dials?
[01:24:10] <zeeshan> haha
[01:24:13] <malcom2073> Haha yeah
[01:24:13] <zeeshan> that shit is terrible dude
[01:24:31] <malcom2073> We need to strip the DRO off our one mill, sell it, and stick it on the bridgeport, then we'll be set

[01:24:38] <zeeshan> furrywolf: can you tell what im trying to make?
[01:24:52] <malcom2073> I tried to click-rotate
[01:24:58] <zeeshan> LOL
[01:25:02] <zeeshan> i do that too sometimes on 3d images
[01:25:39] <furrywolf> a new clamp for your polymer samples?
[01:25:50] <zeeshan> well its the same clamp
[01:26:00] <zeeshan> im trying to make a diffuser for the air
[01:26:06] <zeeshan> if im going at high pressure ramp rates
[01:26:13] <zeeshan> sometimes it blows up the sample w/ the beam of air
[01:26:14] <zeeshan> lol
[01:26:24] <furrywolf> heh, you're worried the air jet is causing enough stress to affect it?
[01:26:26] <zeeshan> im trying to redirect the air away from the pole
[01:26:30] <zeeshan> im not worried man
[01:26:32] <zeeshan> its happened already
[01:26:34] <furrywolf> you can buy sintered brass mufflers very cheaply
[01:26:40] <zeeshan> yea but no room to fit

[01:27:07] <PetefromTn_> another batch of cookies getting ready to go in the oven!! hehehe
[01:27:26] * furrywolf hides in pete's kitchen waiting for the cookies to be done
[01:28:13] <furrywolf> I think the only desert I have right now is a box of whole wheat fig bars.
[01:28:34] <zeeshan> home some white macadamia nut cookies
[01:28:38] <zeeshan> *home = have
[01:28:42] <PetefromTn_> you might not like biting these cookies...they are kinda HARD
[01:28:50] <zeeshan> pete likes it hard
[01:29:00] <PetefromTn_> har har he har
[01:29:21] <furrywolf> bah, so you're making brackets, not cookies? that's no fun!
[01:29:29] <zeeshan> oh
[01:29:29] <zeeshan> wtf
[01:29:31] <zeeshan> youre anodizing
[01:29:34] <greg___> I spent monday rewiring the Emco for single phase. It should work. I spent today trying to figure out how to get 240 into the garage.
[01:29:34] <zeeshan> i really thought you were making cookies

[01:30:04] <furrywolf> also, are you sure they're hard? you're only doing type II, not III. :P
[01:30:11] <zeeshan> greg___: you run 3 wires
[01:30:12] <PetefromTn_> hard enough
[01:30:32] <furrywolf> zeeshan-lab: FOUR! ground and neutral! :P
[01:30:32] <greg___> try chasing which conduit runs make it to the outlet you want to use
[01:30:38] <zeeshan> http://www.space.com/17933-nasa-television-webcasts-live-space-tv.html
[01:30:40] <zeeshan> guys its starting
[01:30:49] <zeeshan> no need for neutral for motor
[01:30:49] <furrywolf> and what is it?
[01:30:53] <zeeshan> PLUTO
[01:31:19] <furrywolf> sure, the motor might not need it... what about the controls? or when you decide to stick a light to it? or a coolant pump? etc. :P
[01:31:23] * furrywolf always runs all four wires
[01:31:26] <greg___> 4 wires for 240 single phase?
[01:32:08] <furrywolf> Hot, Hot, Neutral, Ground... if you're absolutely sure you'll never, ever want to run a 120V load off the same wiring, you can skip the neutral.
[01:32:26] <greg___> everything inside is 240V
[01:32:31] <zeeshan> who you calling hot
[01:32:36] <zeeshan> its l1 and l2
[01:32:38] <zeeshan> !
[01:32:54] <furrywolf> Any non-earthed conductor is "hot".
[01:33:06] <zeeshan> that is not waht the ladies say to me
[01:33:20] <greg___> The coolant pump is 3P but I'm not using it, probably use it for the lathe with a VFD,
[01:33:37] <zeeshan> greg___: i used a vfd for my coolant pump
[01:33:44] <zeeshan> but honestly it's cheaper to just buy another
[01:33:51] <zeeshan> its always going to be at constant speed
[01:34:00] <furrywolf> don't worry, no one calls me hot either.
[01:34:03] <zeeshan> and it'll need to go through a contactor which you can switch with a relay
[01:35:22] <greg___> the contactor is there, but the pump was never hooked up.
[01:35:45] <greg___> If i decide to use coolant i'll find a single phase pump
[01:36:30] <zeeshan> i wasted a vfd on the coolant pump
[01:36:34] <greg___> so tmr pulling 50 ft of 12AWG to an outlet.
[01:36:35] <zeeshan> im not even gonna be using flood coolant

[01:55:23] <PetefromTn_> I must say that after SEVERAL anodizing runs now using this power supply and the shunt MV reading setup the unit is pretty consistent. I mean I almost never have to make fine adjustments of the current during the 2 hour runs
[01:55:48] <greg___> do you think the current meter was off from the start?
[01:56:45] <PetefromTn_> well right now the shunt is reading 41mv on the 47.5" distance and the meter itself is showing anywhere from .9 to 1.0 amps
[01:56:58] <greg___> current should be within a few percent with temperature anyway, whatever temperature coefficient of the shunt is anyway.
[01:57:04] <PetefromTn_> I THINK the actual current is somewhere around 4 amps now
[01:57:06] <zeeshan> http://www.businessinsider.com/first-high-resolution-image-of-plutos-surface-2015-7
[01:57:10] <zeeshan> pluto has a heart!
[01:57:57] <PetefromTn_> I don't remember the formula Furrywolf used to determine the actual current
[01:58:09] <zeeshan> using the current shunt?
[01:58:11] <greg___> same one I was going to use
[01:58:29] <greg___> sorry i had to run, furry took care of you
[01:58:57] <greg___> I have a couple shunts like that I used for rc model stuff
[01:59:03] <PetefromTn_> yeah
[01:59:45] <greg___> i've been thinking about buying a DC clamp meter for like 10 years now
[02:01:20] <greg___> I made a blade fuse adpater to plug in the shunt when i was into car stereo
[02:01:25] <furrywolf> well, somehow, in two weeks of trying to fix the welder, the previous owner didn't identify a set of dirty, sticky points.
[02:02:03] <furrywolf> because, you know, the MOST COMMON PROBLEM is hard to identify.
[02:02:18] -!- kwallace has quit [Quit: Leaving.]
[02:02:35] <greg___> happens. I bought a supposedly dead Dyson vacuum for $20 when just need a good cleaning, like new.
[02:03:06] <greg___> was goign to rob the hose for ours
[02:03:25] <furrywolf> he's a reasonably competent mechanic, said he spent two weeks trying to figure out why it has no spark... looks like he replaced the points... but didn't identify that the little rocker arm was stuck in place. lol
[02:04:02] <greg___> the dyson was crammed with dog hair and carpet powder
[02:04:05] <furrywolf> two drops of penetrating oil and working it back and force with a screwdriver a bunch of times, then running a bit of stiff paper between the contacts, and it runs great.

[02:04:59] <furrywolf> brb, reinstalling gas tank and seeing if it makes power.
[02:05:02] <greg___> spent sunday tearing apart the clothes drier to fix a motor. the oil had dried up over 20 and stuck the rotor. same thing oiled it up and back in business
[02:05:46] <PetefromTn_> this says 14 gauge wire has a resistance of .00297 so 48" of it is .00594
[02:06:20] <greg___> what is the length of your shunt?
[02:06:31] <PetefromTn_> 47.5 actually
[02:06:38] <PetefromTn_> inches
[02:06:54] <furrywolf> PetefromTn_: 48" = 4ft
[02:06:56] <PetefromTn_> and I am maintaining 41mv
[02:07:07] <PetefromTn_> oops
[02:07:14] <PetefromTn_> .01188
[02:07:37] <PetefromTn_> do you just divide then?
[02:07:45] <greg___> yes
[02:07:48] <greg___> 3.45
[02:07:50] <PetefromTn_> by 41mv
[02:08:10] <furrywolf> my table says .002525, not .00297... yay not-quite-standard standards.
[02:08:13] <PetefromTn_> whats 3.45
[02:08:16] <furrywolf> I used the value from my table
[02:08:26] <greg___> .041V/.0119Ohm= 3.45A
[02:08:37] <PetefromTn_> oh okay
[02:08:46] <PetefromTn_> so I guess that is what I am giving it now
[02:08:54] <PetefromTn_> for two of these parts at a time
[02:08:55] <greg___> one or two parts?

[02:09:23] <greg___> everyhting hurtts
[02:09:31] <furrywolf> 47.5 inches using the resistance value from my table gives .0099947916 ohms, or .01. I did this to make a nice round number. :P
[02:09:46] <greg___> close enough for this
[02:10:06] <PetefromTn_> huh?
[02:10:09] <furrywolf> if the value in your table is correct, you actually want 40.4 inches...
[02:10:21] <PetefromTn_> mv
[02:10:39] <greg___> I was reading some stuff on finishing .com and those guy anodize parts in 20-40 minutes
[02:10:47] * furrywolf isn't sure how two awg tables can differ by so much, but is quite sure a proper current meter is the right fix. :P
[02:10:59] <PetefromTn_> all I know is that it is cooking really stable for this setting
[02:11:44] * zeeshan did some calculations
[02:12:00] <zeeshan> to get to alpha centuari , with our fastest craft voyager 1
[02:12:06] <zeeshan> it'd take us 203 years to reach there..
[02:12:07] <zeeshan> :/
[02:12:28] <furrywolf> zeeshan: generation ships
[02:12:37] <zeeshan> i dunno about you
[02:12:45] <zeeshan> but thats a long itme!
[02:12:47] <zeeshan> *time
[02:13:04] <PetefromTn_> these parts are actually .176 sq ft
[02:13:26] <greg___> so you're happy with the finish now?
[02:13:33] <PetefromTn_> I was under the impression that the 3d model I gave my friend was .625 thick but it was actually .75 which is what these current parts are...
[02:13:49] <PetefromTn_> so the prototype parts were getting miscalculated.
[02:13:52] <furrywolf> zeeshan: you pack a ship with a bunch of people and a big reactor with enough fuel to grow food for the whole journey, and they spend 203 years having an 10-generation-long orgy.
[02:14:07] <zeeshan> furrywolf: or you just make faster craft
[02:14:15] <zeeshan> even if you could get to half a light year speed
[02:14:17] <greg___> they wouldn't know what the goal was when they got their
[02:14:23] <zeeshan> theres a lot more to explore
[02:14:28] <greg___> their= there
[02:14:29] <furrywolf> half light speed is hard to get to. :P
[02:14:32] <PetefromTn_> it took almost nine years for horizton to reach pluto right/
[02:14:37] <zeeshan> yea pete
[02:15:03] <PetefromTn_> and that is just from a particular orbit and NO propulsion
[02:15:44] <zeeshan> it launched with propulsion :D
[02:15:45] <PetefromTn_> the only propulsion it has is just to change its orientation I think?
[02:15:49] <zeeshan> yea
[02:15:55] <zeeshan> no more speed boosts
[02:16:01] <PetefromTn_> yeah but once it was in space it was just like a sail
[02:16:06] <zeeshan> i think the last gravity assist it used was juipter
[02:16:24] <furrywolf> now, bbl, I'm talking about current shunts when I should be putting the gas tank back on the welder.
[02:17:28] <PetefromTn_> there is an episode of DS9 where Capt. Benjamin Sisko and His son built a solar sail powered craft that the ancient Bajorans traveled the galaxy with it was pretty cool and I understand it could actually work
[02:19:52] <zeeshan> omg i gotta share this with you guys

[02:23:53] <PetefromTn_> greg___ How did they anodize parts in 20-40 minutes?
[02:24:54] <greg___> dunno, 12-15A/sqft probably thin coating spec as well.
[02:26:05] <greg___> I dont' think i have the tabs open anymore
[02:26:46] <PetefromTn_> if my parts are .1755 each that is .351 total sq/ft
[02:27:24] <PetefromTn_> with 3.8 amps as you said that is what 10.83 amps/sqft I guess
[02:27:27] <greg___> you could easily double the current and halve the time
[02:27:50] <PetefromTn_> not sure you can really
[02:28:00] <PetefromTn_> it might get hotter in the bath
[02:28:39] <greg___> oh right there is the temperature, they run chillers. time costs more the electricity
[02:29:00] <PetefromTn_> yeah
[02:29:07] <tiwake> industrial electricity is cheap
[02:29:09] <PetefromTn_> according to the 720 calculator
[02:29:09] <greg___> some of them had 5000A rectifiers
[02:29:21] <PetefromTn_> I should be at 4.26 amps
[02:29:32] <PetefromTn_> and that takes only 60 minutes apparently
[02:29:37] <PetefromTn_> but requires 30 volts
[02:29:43] <PetefromTn_> and I doubt I would get that
[02:30:01] <greg___> Most of them only ran 15V max
[02:30:16] <greg___> maybe 17V
[02:31:16] <greg___> chemistry in the bath might be optimized too
[02:36:34] <PetefromTn_> If I can get all these parts done successfully I will try to purchase a better quality anodizing power supply in a little while.

[02:47:22] <furrywolf> no AC generator output, but I think that's user error. googling a manual now.
[02:49:46] <renesis> petefromtn_: most panel meters like that will have two pots, one for offset and one for gain
[02:49:58] <renesis> do the offset one first

[03:02:39] <zeeshan> and cylinder along the other part
[03:02:45] <zeeshan> drill the holes in a dividing head
[03:02:53] <zeeshan> then chop off the excess on the lathe
[03:02:55] <zeeshan> whatcha think? :D

[03:09:54] <zeeshan> ive only need square and hex
[03:10:02] <PetefromTn_> hex usually
[03:10:45] <greg___> 1.25 won't fit in 5C
[03:11:33] <greg___> but for one part i'd just make a 1" spigot

[03:28:28] <furrywolf> anyone want to buy a welder? :)
[03:30:12] <zeeshan> no
[03:30:19] <zeeshan> did you fix it
[03:30:53] <furrywolf> yes
[03:31:37] <furrywolf> it's a miller aea-200le, 250A AC 100% duty cycle, cast iron Onan engine, electric start, 5kW AC generator.
[03:32:54] <furrywolf> I have no idea how someone claiming to be a competent mechanic can take two weeks and not figure out that the arm that moves the points was stuck. lol
[03:33:55] <zeeshan> one that shit talks
[03:34:50] <furrywolf> the sad thing is, I know that's not entirely a bullshit claim, because someone I know hires him when he needs moderate-skill grunt work done, like changing transmissions or axles...
[03:35:38] <furrywolf> and things generally work when he's done
[03:35:57] <PetefromTn_> anyone can miss things
[03:35:58] <zeeshan> oh hes a car mechanic..
[03:36:05] <zeeshan> car mechanics don't fix machinery
[03:36:16] <furrywolf> I'll chalk it up to "kids these days"... I don't think they've made things with points since before he was born. :)
[03:38:01] <furrywolf> the welder seems in good condition... I'll probably put a new battery in it, maybe a pair of mufflers, scrub some of the dust off it, and resell it.
[03:38:17] <zeeshan> those generator type welders go for serious money
[03:38:21] <PetefromTn_> don't forget some shiny paint!
[03:38:27] <zeeshan> i bet you can get 1500 bux for it?
[03:38:48] <furrywolf> it has what sounds like a bearing howl, but oiling the only non-engine-lubricated bearing makes absolutely no difference, so I don't know what it is. I tried cleaning the slip rings too, as they were a little black and chunky on the edges, but no change with that either.

[03:39:37] <PetefromTn_> nice...
[03:39:37] <furrywolf> zeeshan-lab: nah, it's pretty old... maybe $800.

[03:41:29] <PetefromTn_> I ordered some stainless fasteners from Mcmaster carr yesterday afternoon
[03:41:30] <furrywolf> PetefromTn_: yep. I only need two for now, though... a 7i76e for the shoptask, and whatever the cheaper ethernet board with a parallel port is for the sherline. (I'm tempted to say 7i92, but don't quote me on that)
[03:41:36] <PetefromTn_> they did not get here today which is not typical
[03:42:17] <renesis> intern ordered some shit this morning
[03:42:24] <renesis> got here like around 4
[03:42:42] <furrywolf> can anyone think of any possible reason I'd need to encode both spindles on the shoptask at once? because if not, I'm just going to switch them with a relay to the main encoder input.
[03:43:35] <zeeshan> furrywolf: encode them both
[03:44:09] <zeeshan> https://www.youtube.com/watch?v=i3XopQAOtEc
[03:44:11] <zeeshan> you can do this!@
[03:44:16] <furrywolf> yes, I plan on encoders on them both... but do I need them both AT ONCE?
[03:44:21] <zeeshan> yes
[03:44:23] <zeeshan> turn milling!!!!!!
[03:45:23] <PetefromTn_> definitely on the lathe
[03:45:56] <zeeshan> man if i had a 5 axis
[03:45:59] <zeeshan> this part would be a joke to make
[03:47:02] <PetefromTn_> was just screwing around with the power supply out there.
[03:47:17] <furrywolf> the only possible thing I can think of doing with encoders on both at once would be gear hobbing, but since they intersect I don't think I could do that without lots of extra hardware anyway, so I'm going to go with no, I don't need both encoders at once.
[03:47:26] <PetefromTn_> I cranked it up to see what kind amps it would go to in the setup it has with 2 parts now
[03:47:35] <PetefromTn_> I got 83.3mv
[03:47:46] <PetefromTn_> which I think is something like 7 amps
[03:48:07] <furrywolf> it should be 8.3A if the shunt is accurate.
[03:48:08] <PetefromTn_> the voltage did not increase over 16 tho on the meter
[03:48:25] <furrywolf> the voltage will increase when the coating gets thicker.
[03:48:27] <PetefromTn_> really?
[03:48:34] <renesis> that means its in current mode?
[03:48:41] <PetefromTn_> I used the formula from before
[03:48:47] <PetefromTn_> yeah current mode
[03:48:53] <zeeshan> https://youtu.be/tReocetJD2E?t=167
[03:48:57] <renesis> yeah because the oxide reduces conductivity, so more voltage for given current
[03:48:58] <zeeshan> boy this machine moves fast during rapids
[03:49:01] <zeeshan> i want a real lathe
[03:49:01] <zeeshan> :(
[03:49:03] <PetefromTn_> .083/.01190
[03:49:25] <renesis> you need to make sure the voltage is set high enough it doesnt go back into constant voltage mode
[03:49:26] <furrywolf> PetefromTn_: the table you pasted gives a slightly different resistance value than the other two tables I checked. without actually measuring, there's no way to know which is right.
[03:49:40] <renesis> it also changes with temp
[03:49:48] <PetefromTn_> renesis I had the voltage maxed
[03:49:55] <PetefromTn_> this is supposed to be a 30v machine
[03:49:56] <renesis> cool
[03:50:06] <PetefromTn_> furrywolf OK
[03:50:12] -!- pcw_home has quit [Ping timeout: 264 seconds]
[03:50:14] <PetefromTn_> I was just glad it went up that high
[03:50:28] <PetefromTn_> I was thinking I would not be able to get even to 4 amps heh
[03:51:08] <furrywolf> the two tables I checked give .002525, which at 47.5 inches is .0099947916, or .01. 83.3/.01 is 8.3A...
[03:51:31] <PetefromTn_> sweet even better
[03:51:44] <furrywolf> I picked that length to give you an exact round number, so no actual math is needed. :)
[03:51:47] <PetefromTn_> that is at least close to the max output it is supposed to be able to provide
[03:52:02] <PetefromTn_> aah
[03:52:03] <furrywolf> of course, there's a lot of variation between wire... if we're within 20% we're doing good.
[03:52:04] <PetefromTn_> sweet
[03:52:37] <PetefromTn_> ten minutes to more cookies!
[03:52:46] <furrywolf> when you get a working current meter, use both it and your shunt at once, to check the accuracy of the shunt. then use whatever you find to scale the records you've been keeping.
[03:52:51] -!- arrowbook has quit [Read error: Connection reset by peer]
[03:52:57] <PetefromTn_> perhaps I judges this power supply too harshly initially
[03:53:15] <furrywolf> that is, if the shunt said you were doing 2.1A, but the proper meter says 1.5A, make a note of this, so you know what you were actually doing with each of the tests.
[03:53:32] <PetefromTn_> it sure seems to be consistent and has power enough to do probably three or four of these parts at once
[03:54:04] <furrywolf> it'll probably start overheating again.
[03:54:40] <PetefromTn_> possibly but it seems very stable now and not even warm really. I honestly think we were much higher than we thought on those first tests
[03:55:31] <PetefromTn_> I would love to have a nice powerful lambda or even one of those mastec better chinese ones
[03:55:42] <furrywolf> the 7i76e has a single dedicated spindle encoder input... if I don't need to encode both spindles at once, and I can't possibly think of a situation where I'd need to (or even run both at once!), I'll multiplex both to the single input.
[03:55:42] <renesis> fuck my mastech
[03:56:12] <PetefromTn_> send it to me :D
[03:56:18] <renesis> either voltage reg is fucked, or voltage adjust pot is super fucked
[03:56:29] <renesis> i dont even know if i took it from last job
[03:56:41] <PetefromTn_> which model is it?
[03:57:10] <renesis> i dunno, triple output, 30V, maybe 10A
[03:57:22] <PetefromTn_> wow triple output?
[03:57:28] <PetefromTn_> I have seen dual
[03:57:32] <renesis> normal bench supply
[03:57:47] <renesis> lots of dual are triple, the third is usually just a 5V fixed
[03:58:07] <PetefromTn_> oh okay
[03:58:44] <renesis> so it has two 30V/10A, and switches to set them up master/slave in parallel or series
[03:59:10] <renesis> the 270 deg pots with no fine is pretty annoying, too
[03:59:35] <furrywolf> PetefromTn_: with what the process seems to be costing, spending $250 on a supply probably isn't too unreasonable, and will hopefully pay for itself.
[03:59:43] <furrywolf> the good lambda ones tend to sell around $150-$250
[03:59:51] <furrywolf> I suspect other american brands are similar
[03:59:59] <zeeshan> f that
[04:00:05] <zeeshan> bust out the car battery
[04:00:08] <zeeshan> and jumper cables

[04:04:07] <furrywolf> he needs more than 12V.
[04:04:39] <zeeshan> NO!
[04:04:59] <furrywolf> and for that price he can get a used american one that'll outlast it.
[04:05:03] <renesis> used a lot of their china stuff at work, its branded with the company name. its not some random ebay seller, they sell to labs
[04:05:21] <furrywolf> (the one renesis pasted, not the $50 one)
[04:06:07] <renesis> the one i pasted is 30v/20a?
[04:07:21] <renesis> and right im saying if he wants decent new china shit from someplace that will answer the phone, that sells to engineering labs
[04:07:43] <furrywolf> yes. and I'm saying rather than china shit, he should buy a used non-china supply for less money.
[04:07:54] <renesis> http://www.circuitspecialists.com/csi3010sw.html
[04:08:16] <renesis> in their low cost section
[04:08:20] <furrywolf> a 20 year old american supply is probably less than half into its life, while 20 years is about 20 times the life expectancy of a chinese supply used for continuous power...

[04:09:43] <zeeshan> silly
[04:09:58] <renesis> i think 'mean well' stands for 'badass reservoir of power'
[04:09:59] <PetefromTn_> parts are in the dye..
[04:10:05] <PetefromTn_> probably last batch for the night
[04:10:11] <PetefromTn_> gonna hit it again in the morning
[04:10:44] <renesis> furrywolf: they make a lot of stuff now, all i really trust them for, and what i think they made a name for themselves in, was open frame psu and similar
[04:10:45] <furrywolf> now you need to build a robot that moves parts between the tanks for you.
[04:10:48] <os1r1s> PetefromTn_: Good results today?
[04:10:57] <PetefromTn_> I would just like a supply that would allow say four of these parts at one time without overheating
[04:11:07] <PetefromTn_> os1r1s yeah man pretty damn good..
[04:11:22] <renesis> was it current or did you rinse diff?
[04:11:33] <os1r1s> PetefromTn_: Any pics?

[04:11:47] <renesis> nice
[04:11:48] <zeeshan> sweeeeeeeeeeeeet
[04:12:00] <PetefromTn_> yeah I am pretty pleased with that
[04:12:10] <os1r1s> PetefromTn_: That looks spot on
[04:12:11] <PetefromTn_> that is the best one yet but most are pretty close to that
[04:12:25] <furrywolf> hrmm. I bet I could sell fake remote reservoirs for shocks.
[04:12:38] <PetefromTn_> HEY!!!
[04:12:48] <PetefromTn_> don't steal my thunder man!
[04:13:12] <os1r1s> PetefromTn_: Too bad you are on the east side of the state. I'd loan you my power supply to play with
[04:13:40] <PetefromTn_> honestly this one is working fine right now just wish the readouts were accurate
[04:13:53] <furrywolf> just make injected molded plastic bottles and clamps that look like the real thing, painted with fake anoidze paint, with a bit of cheap stainless hose sticking out the top with a clip that connects to the upper bolt on the shock...
[04:13:54] <PetefromTn_> and once I get some spare coin I will try to get a lambda or something
[04:14:16] <renesis> petefromtn_: hit me up in like a couple months when i am back home, i can test the mastech and if it works i sell it to you cheap if you want
[04:14:39] <furrywolf> I am quite sure there's people who would pay for fake parts that make their truck look like it has fancy shocks when all it actually has are stock shocks.
[04:15:47] <PetefromTn_> renesis thanks man that would be sweet
[04:15:58] <PetefromTn_> I could really use something with a bit more AZZ
[04:16:02] <furrywolf> just like how you can buy fake beadlocks, fake disc brakes, and all sorts of other crap. :P
[04:16:17] <renesis> i just remember being pissed that the voltage kept drifting a few tenths
[04:16:18] <PetefromTn_> furrywolf what are you trying to say?
[04:16:33] <renesis> might work fine for what you are doing
[04:16:50] <PetefromTn_> renesis well as long as the current maintains pretty good it should be good for this app
[04:17:05] <PetefromTn_> I am kinda enjoying this anodizing stuff
[04:17:06] <renesis> right i dont remember ever having issues with it in CC mode
[04:17:09] <furrywolf> PetefromTn_: I'm trying to say I've thought of a way to make money off idiots.
[04:17:27] <renesis> its a bit touchy to set because only single turn coarse pots
[04:17:37] <PetefromTn_> it is pretty cool to see the parts I designed all nice and black and smooth
[04:17:54] <renesis> the finish on that is nice
[04:17:57] <renesis> anodizing aside
[04:18:17] <os1r1s> PetefromTn_: You can also etch with a laser or engraving bit before sealing.
[04:18:19] <PetefromTn_> I am looking forward to getting these parts finished so I can start playing with other colors and combos
[04:18:23] <furrywolf> PetefromTn_: the novelty will wear off and then it will just be more work. :P
[04:18:31] <PetefromTn_> sure
[04:18:46] <os1r1s> I laser etch anodized stuff with good results.
[04:18:48] <PetefromTn_> some of the cooler parts I have seen are anodized/engraved
[04:18:55] <PetefromTn_> you got a CNC laser?
[04:18:57] <renesis> gotta try those swirled multi color coats
[04:18:59] <os1r1s> PetefromTn_: Yes
[04:19:06] <PetefromTn_> damn thats nice
[04:19:13] <PetefromTn_> is it DIY or bought
[04:19:44] <os1r1s> PetefromTn_: My favorite test piece.
[04:19:45] <os1r1s> http://mounicou.com/laser/aztec.jpg
[04:19:47] <PetefromTn_> I know a lot of folks want custom electronics panels that are anodized/engraved I wonder if I could get into selling something like that
[04:19:57] <os1r1s> PetefromTn_: Hustled off of ebat
[04:20:00] <os1r1s> ebay
[04:20:04] <PetefromTn_> cool aztek calendar
[04:20:24] <os1r1s> PetefromTn_: That card is the size of a standard bus card
[04:20:29] <os1r1s> So its decently detailed
[04:20:30] <PetefromTn_> I really need to come up with some more ideas for products I can sell
[04:20:37] <renesis> heh, anodized Al panels on rack gear, i always worry
[04:20:45] <os1r1s> PetefromTn_: I do this for some cash on the side ...
http://mounicou.com/laser/rebeltmb.jpg
[04:21:10] <renesis> petefromtn_: how much you think you sell a panel for?
[04:21:14] <PetefromTn_> yeah I am looking for products that I can machine and sell in reasonable numbers
[04:21:16] <renesis> like, 10 pc runs
[04:21:23] <renesis> 2u
[04:21:27] <os1r1s> Anyway, if you want me to etch something I'll happily do it for free so you can see.
[04:21:33] <PetefromTn_> no idea I guess it depends on what it is and how elaborate
[04:21:45] <PetefromTn_> and the size of course
[04:21:48] <renesis> right but totally ballpark bullshit
[04:22:09] <PetefromTn_> I hate ballparking stuff it never ends well ;)
[04:22:23] <renesis> 2u is 19 x 3.5, would be 3/16" thick and lots of engraving
[04:22:34] <PetefromTn_> whats a 2u?
[04:22:42] <renesis> i would be doing this for a year anyway so you lose or gain nothing
[04:22:59] <renesis> 2 rack units, a vertical rack unit is 1.75"
[04:23:11] <PetefromTn_> are you seriously wanting someone to do this for you?
[04:23:23] <renesis> 1u and 2u are common, 3u happens on psu and amps, 4u is rare
[04:23:40] <PetefromTn_> okay I am not familiar with that.
[04:23:47] <renesis> probably, my machine needs two setups so its only good for prototyping

[04:27:46] <renesis> whats newcar?
[04:28:02] <furrywolf> a '84 subaru GL wagon
[04:28:18] <renesis> that car has no zoom
[04:28:46] <furrywolf> it doesn't need zoom, because it has 4x4, so can move closer to the object needing photographing. :P

[04:36:03] <furrywolf> Traffic was stopping on the freeway... I stopped... nice and slowly, didn't slam on the brakes or anything... the person behind me simply didn't notice.
[04:36:27] <furrywolf> that was three weeks ago. I'm finally being able to move around without too much back pain, and can mostly feel my leg now.
[04:36:50] <PetefromTn_> parts are in the sealer.. hopefully soon I will have yet another pair ready to ship hehe

[04:38:26] <furrywolf> it was one of the ones where it slides into a shell with latches on the sides. the latches crunched.
[04:38:57] <furrywolf> the new one is a pretty ugly color combination, but it has a reallllly straight body.
[04:39:05] <renesis> yeah thats not so surprising
[04:39:15] <furrywolf> my one that got crunched had an absolutely perfect body. rare, hard to find.

[04:40:20] <furrywolf> I put a LOT of work into that car... I bought it from out of state (there's no rust-free subarus here), replaced tons of parts to restore it to like-new...
[04:40:31] <furrywolf> and one inattentive driver later, it's a parts car.
[04:40:53] <furrywolf> the one I'm getting tomorrow is in this state, but not this part of it...
[04:40:57] <furrywolf> closer to the far side of it
[04:41:08] <furrywolf> about five hours each way
[04:41:08] <renesis> where?
[04:41:14] <furrywolf> Chico area
[04:41:19] <renesis> sierras?
[04:41:33] <furrywolf> no, central valley
[04:41:35] <renesis> oh neat say hi to home
[04:41:39] <PetefromTn_> I used to live in Sacto
[04:41:48] <PetefromTn_> been to chico
[04:41:57] <renesis> sac is kind of weird but i like the big park
[04:41:57] <PetefromTn_> been all over that area actually
[04:42:18] <PetefromTn_> my wife's father lives in North Highlands
[04:42:26] <furrywolf> I don't go that far south (sacto) unless I have to.
[04:42:43] <PetefromTn_> my wife's sisters family is in redding
[04:42:55] <PetefromTn_> we visited there a year or two ago for like ten days
[04:43:02] <PetefromTn_> drove up to shasta lake
[04:43:12] <PetefromTn_> down to Frisco
[04:43:15] <renesis> shasta on a clear day is awesome
[04:43:18] <PetefromTn_> and all around Sacto again
[04:43:22] <PetefromTn_> yeah it is
[04:43:23] <furrywolf> that's a long way from tn.
[04:43:30] <PetefromTn_> sure as hell is
[04:43:38] <PetefromTn_> thank god for planes
[04:43:42] <furrywolf> renesis: Shasta right now is a wading pool, from what I've heard.
[04:43:49] <PetefromTn_> and father in law's spare vehicles
[04:43:56] <renesis> i just like the big volcano thing
[04:44:04] <renesis> ive only stopped there to eat
[04:44:23] <PetefromTn_> used to jetski on folsom lake and lake elsinore

[04:45:51] <renesis> cachuma is like that
[04:46:00] <renesis> they were like that when i was a kid, too
[04:46:17] <furrywolf> that's not shasta, but shasta is supposedly similar right now
[04:46:36] <renesis> couple el ninos will happen, big earthquake will make people move away, and itll be closer to normal again
[04:47:31] <furrywolf> http://cdn.theatlantic.com/assets/media/img/photo/2014/09/dramatic-photos-of-californias-historic-drought/c19_54430296/main_900.jpg there's one of shasta
[04:47:55] <renesis> looks cool!
[04:48:41] <furrywolf> http://cdn.theatlantic.com/assets/media/img/photo/2014/09/dramatic-photos-of-californias-historic-drought/c22_53834034/main_900.jpg heh! houseboaters having to get cozy with their neighbors, due to their anchorages now being above the water line. :)
[04:48:52] <renesis> anyway, theyve all been at stages of low my whole life
[04:49:02] <furrywolf> a few more feet and they'll really have a problem...
[04:50:00] * furrywolf generally finds people with houseboats to be people with too much money, and thus likes when bad things happen to them
[04:50:14] <renesis> mean
[04:52:16] <furrywolf> bbl, wolfy bedtime
[04:52:29] <PetefromTn_> http://i.imgur.com/50XgocA.jpg
[04:52:39] <PetefromTn_> progress so far on customers parts
[04:52:57] <PetefromTn_> flash picks up dry pockets
[04:53:12] <PetefromTn_> I need to get a spray bottle for my WD40 tomorrow
[04:54:04] <furrywolf> hrmm, you have to oil them to make them shiny? is that normal?
[04:56:56] <PetefromTn_> I dunno but they seem to suck in the wd40 and I have read that in other peoples anodizing pages.
[04:57:27] <PetefromTn_> when they come out of the sealer they are actually quite dry looking and the fluid actually dries on them quickly
[04:58:06] <PetefromTn_> after I wipe them with WD40 they seem to keep the shine even when I wipe them with acetone again
[04:58:12] <PetefromTn_> kinda strange
[04:58:18] <PetefromTn_> I hope that is normal
[04:58:36] <PetefromTn_> the parts sure look and feel like a typical anodized part does
[04:59:01] <PetefromTn_> and I took one to my local customer and he described it as good as some of the fuel rails they buy online
[04:59:27] <furrywolf> that's good.
[04:59:28] <furrywolf> bbl, bedtime

[06:11:18] <tiwake> evidently thats "BeagleBone Black running Machinekit/LinuxCNC"
[06:11:40] <archivist> and comes with a blunt tool!
[06:12:30] <tiwake> looks like you cant get any more
[06:12:39] <tiwake> all the tiers with the mill are gone
[06:12:57] <archivist> I would not be wanting one
[06:13:03] <tiwake> me neither
[06:18:23] -!- arrowbook has quit [Read error: Connection reset by peer]
[06:19:49] <tiwake> the interesting part is I used to live in that town
[06:19:59] <tiwake> there is a slight chance I know those people
[06:20:04] <tiwake> but I'm not seeing a name
[06:20:29] <archivist> iirc the name is/was on the blog fo rit
[06:22:04] <tiwake> was just noticing
[06:22:49] <tiwake> overall part accuracy +-0.005"
[06:22:54] <tiwake> thats kinda horrible
[06:23:21] <archivist> look at how the steppers have to resist cutting force on the rotaries
[06:24:29] <tiwake> thats what you get for a $3,000 machine
[06:24:37] <archivist> some bad design errors but pretty for the domestic maker who does not know the difference between a thou and an inch
[06:25:06] <tiwake> its probably fine for some stuff
[06:25:29] <tiwake> it would probably be nice for doing weird engraving stuff
[06:25:46] <tiwake> ...on a small part
[06:26:39] <archivist> if you want a real giggle see
http://www.ebay.co.uk/itm/310562732677 this has an impossible accuracy claim
[06:27:17] <tiwake> I don't metric
[06:27:24] * tiwake grabs a calculator
[06:27:52] <archivist> now I messaged the seller, they use a C6 ballscrew
[06:28:02] <tiwake> wait what
[06:28:25] <tiwake> a C6 ballscrew has like 0.003" or more of backlash
[06:28:28] <tiwake> or so
[06:29:04] <archivist> yes you heard right :)
[06:29:25] <archivist> fraudulent claims
[06:29:27] <tiwake> and they are claiming 0.0004" of accuracy
[06:30:26] <archivist> probably they can get to 5 thou with care
[06:31:52] <tiwake> yeah, about 10-12x worse accuracy than advertised

[12:59:48] <PetefromTn_> mornin'
[13:01:49] <_methods> hola
[13:01:53] <_methods> got some part pics
[13:02:10] <PetefromTn_> I posted a bunch already heh
[13:02:21] <_methods> ah nice
[13:02:27] <PetefromTn_> they still look like that basically
[13:02:35] <skunkworks> happy?
[13:02:38] <PetefromTn_> so far I am just short of halfway thru
[13:02:52] <_methods> ah you went into full production
[13:03:00] <_methods> how's your power supply holding up
[13:03:05] <PetefromTn_> LOL I guess you could say that
[13:03:12] <PetefromTn_> its okay
[13:03:20] <PetefromTn_> it actually seems to be quite consisten
[13:03:22] <PetefromTn_> t
[13:03:27] <_methods> good
[13:03:50] -!- gadue has quit [Ping timeout: 265 seconds]
[13:03:57] <PetefromTn_> yeah I am sure a better supply would work better and allow more parts per run
[13:04:18] <_methods> meh looks like yours is going to work
[13:04:21] <PetefromTn_> but so far it is doing what I have asked it to despite not giving me accurate current information
[13:04:33] -!- gadue [gadue!SB@131.114.31.60] has joined #linuxcnc
[13:04:45] <_methods> well i bet if you get a multimeter you'll find it's not that far off
[13:04:50] <PetefromTn_> yesterday at the end of a part run I was screwing around with it
[13:05:14] <PetefromTn_> and I cranked it up as far as it would go without switching to CV mode
[13:05:31] <_methods> how far did it get?
[13:05:33] <PetefromTn_> and got 83.3 mv which should be close to 8.3 amps
[13:05:48] <_methods> ah good
[13:05:51] <PetefromTn_> yeah honestly it is not possible that it is not wrong
[13:06:19] <PetefromTn_> if it was only putting out the 1.6 or 1.5 amps it says it is during these runs the parts would not get anodized correctly
[13:06:42] <PetefromTn_> the combined surface area of the two parts is something like .355 sq ft.
[13:06:57] <PetefromTn_> which should take like 4.6 amps
[13:07:16] <SpeedEvil> 4.6 vs 1.6A will not matter, if you adjust teh time properly
[13:07:19] <PetefromTn_> I have been setting it to .41 mv which should be like 4.1 amps
[13:07:20] -!- FinboySlick [FinboySlick!~shark@74.117.40.10] has joined #linuxcnc
[13:07:39] <SpeedEvil> and also may not matter if you've got a wide range of acceptable thicknesses - and are in the middle of it
[13:07:51] <PetefromTn_> SpeedEvil yeah I understand that but what I am saying is the Current meter on the display is only showing like 1.2-1.5 amps
[13:08:31] <PetefromTn_> so it is probably way off for some reason....or it reads the load differently than I understand it should
[13:09:21] <PetefromTn_> 1.2 amps is not enough to fully anodize these two parts in 2 hours as I understand it but I am total newb jere
[13:09:23] <_methods> proof is in the puddin'
[13:09:29] <_methods> and you got good parts so screw it
[13:09:36] <PetefromTn_> yeah I suppose so
[13:09:47] -!- skorasaurus has quit [Ping timeout: 240 seconds]
[13:09:48] <PetefromTn_> one question I did have came up last night
[13:09:49] <Tom_itx> if you ever open it, i would look for a cold solder joint somewhere
[13:09:59] <PetefromTn_> was hoping to ask Captainhindsight
[13:10:18] <PetefromTn_> when the parts get out of the dye bath they are nice and black
[13:10:38] <PetefromTn_> and then I put them in the nearly boiling sealer bath with the nickel acetate in it
[13:10:44] <PetefromTn_> for like 15 minutes
[13:11:09] <PetefromTn_> when they come out they are quite matte looking on the surfaces and the water wicks off of them quickly
[13:11:26] <PetefromTn_> then I take them and wipe them down with acetone as I have read you should do
[13:11:32] <_methods> how long are you leaving it in desmut?
[13:11:48] <PetefromTn_> nearly NO dye comes off on the acetone rag
[13:11:57] -!- Daerist has quit [Read error: No route to host]
[13:12:03] <PetefromTn_> so I believe I have made a successful anodizing and sealing
[13:12:32] <PetefromTn_> the parts look smooth and even after I wipe them down with the acetone but they are not really shiny and appear dry looking
[13:12:45] <PetefromTn_> then I wipe them down with a rag soaked with wd40
[13:12:56] <PetefromTn_> and they start to look like I would expect them to look
[13:13:04] <_methods> i read that if you leave them in desmut too long it will make them look like that
[13:13:11] <PetefromTn_> even if I wipe them with acetone again
[13:13:13] <_methods> the less time in desmut the shinier they will be
[13:13:20] <PetefromTn_> they still mostly appear shiny
[13:13:37] <PetefromTn_> I am not sure if this is normal or not
[13:13:45] <_methods> http://bryanpryor.com/anodizing.php
[13:13:51] <_methods> the cleaning the parts section
[13:13:56] <_methods> on desmut
[13:14:06] <_methods> he says too long can dull the parts
[13:14:08] <PetefromTn_> I have taken them individually and rubbed the crap out of them with a clean dry rag
[13:14:39] <PetefromTn_> to remove any surface oil from the WD40 and they remain looking like they should
[13:14:45] <PetefromTn_> I read that too
[13:14:55] <PetefromTn_> but I only keep it in there for maybe two minutes or so
[13:15:05] <_methods> maybe try 1 minute?
[13:15:12] <PetefromTn_> I could
[13:16:01] <PetefromTn_> every part I did even before the etch bath setup was here I got the parts out of the sealer and they looked dry like that
[13:16:34] <PetefromTn_> even the parts I did with the solvent dye were like that when they came out of the sealer bath
[13:17:01] <PetefromTn_> so I honestly do not know if that is correct or not
[13:17:24] <FinboySlick> I'm reading this and thinking: Sure is nice that we have the Internet now to figure stuff like that out. Imagine how much worse Pete's struggle would be otherwise.
[13:17:26] <PetefromTn_> but like I said the parts are definitely sealed and anodized because the acetone rag does not remove hardly any dye
[13:17:43] <PetefromTn_> FinboySlick I agree
[13:17:51] <PetefromTn_> this is a very valuable resource
[13:17:57] <Tom_itx> bbs
[13:17:59] <_methods> yeah you used to have to go to a LIBRARY
[13:19:05] <PetefromTn_> I'm telling you tho that the parts look and feel really nice after I wipe them down with the WD40 and even if I really rub on them with a dry clean towel they still retain that nice smooth semi-shiny look
[13:19:13] <PetefromTn_> I hope that is correct
[13:19:27] <Tom_itx> find out before delivery...
[13:19:56] <PetefromTn_> I know that people often RE-anodize parts
[13:20:18] <PetefromTn_> which requires you to put the part in the etch bath until the old layer is removed along with the dyes
[13:20:30] <PetefromTn_> which would require a bit of time soaking in it
[13:20:47] <PetefromTn_> and then they re-anodize
[13:21:01] <PetefromTn_> if it was a big problem that would probably not be possible
[13:22:25] -!- Tecan has quit [Quit: Live Long And Phosphor!]
[13:27:31] <PetefromTn_> well I am gonna get the stuff going again here
[13:28:01] <Tom_itx> a tool changer would allow you to spend more time with it

[13:41:59] <PetefromTn_> Okay
[13:42:07] <PetefromTn_> was worried about this a bit
[13:42:12] <PetefromTn_> just took one of the parts
[13:42:19] <PetefromTn_> and took it to the kitchen sink
[13:42:34] <PetefromTn_> and cleaned the crap out of it with dawn dishwashing detergent
[13:42:49] <PetefromTn_> which should easily remove any grease or oil
[13:42:57] <PetefromTn_> and dried with a clean towel
[13:43:08] <PetefromTn_> this is the picture of what it looks like after that
[13:43:19] <PetefromTn_> as you can see it is still pretty shiny
[13:43:53] <PetefromTn_> I think that is what a clean dry anodized part should look like no?
[13:44:54] -!- asdfasd [asdfasd!~332332@90.196.232.160] has joined #linuxcnc
[13:45:01] <PetefromTn_> also keep in mind that the part have slight brushed finish before anodizing
[13:45:09] <PetefromTn_> these are NOT full polished parts
[13:45:29] <furrywolf> looks nice to me, but I'm no expert.
[13:45:34] <PetefromTn_> I use the scotch brite wheel on them
[13:45:46] <PetefromTn_> and I use a red pad on the flat surfaces
[13:45:53] <furrywolf> when I was buying fittings for my subaru, I spent extra to get black painted instead of red+blue. :P
[13:45:57] <_methods> so what's wrong with that part?
[13:46:01] <PetefromTn_> furrywolf thanks I was just concerned about this last night
[13:46:16] <PetefromTn_> _methods I am not sure anything is wrong with them
[13:46:38] <PetefromTn_> just that when they come out of the sealer bath they are quite flat/matte looking and water dries on them quickly
[13:46:43] <_methods> i was gonna say looks good to me
[13:46:53] <PetefromTn_> then i take them and wipe them with acetone
[13:47:08] <PetefromTn_> and they get sort of dull looking but almost NO dye comes off on the rag
[13:47:18] <PetefromTn_> so then I wipe them with wd40
[13:47:36] <_methods> only thing i can think is to try a shorter desmut time to experiment with
[13:47:42] <_methods> see if it comes out shinier
[13:47:46] <PetefromTn_> and furry last night made the comment rightfully so asking if they need to be wiped with oil to appear shiny
[13:48:17] <PetefromTn_> I am not sure really what they are supposed to look like immediately when they come out of the sealer bath
[13:48:40] <furrywolf> I'm waiting for a call from the person who'll be helping me drive, then off to pick up a car... yay long drives.
[13:48:48] <_methods> i have no idea, the only anodizer near here closed up shop like 4 years ago
[13:48:50] <PetefromTn_> but this is why I just thoroughly cleaned a part with dawn dishwashing detergent to remove all surface oils
[13:49:03] <_methods> otherwise i'd head over there and ask them lol
[13:49:11] <PetefromTn_> and wiped it with a clean dry rag so I could see what the surface actually looks liek now without oil
[13:49:25] <_methods> nobody wants to have anything to do with finishing/plating anymore
[13:49:37] <PetefromTn_> that last picture is what it looks like
[13:49:57] <PetefromTn_> I tried to turn it to catch the light so you guys can see the surface better
[13:50:04] -!- LikeVinyl has quit [Ping timeout: 256 seconds]
[13:50:20] <PetefromTn_> I have had a lot of anodized parts over the years made by others
[13:50:30] <PetefromTn_> and this sure appears to look like they do
[13:50:50] <PetefromTn_> even completely dry of oil AFTER being at first wiped down with it.
[13:50:52] <_methods> yeah i can't remember the last time i had regular anodized parts done
[13:50:55] <furrywolf> which is a very good sign.
[13:50:59] <_methods> most of what we get is hard coat
[13:51:14] <PetefromTn_> I hate not knowing tho
[13:51:54] <furrywolf> That's called learning. :)
[13:52:01] <PetefromTn_> personally I feel like if I can scrub it by hand with damn and clean it off and it STILL looks pretty good and shiny that is a good sign. It has not lost ANY of the color and the rags are clean
[13:52:31] <PetefromTn_> furrywolf yeah man I agree it IS a learning process
[13:53:07] <_methods> https://metaltronics.wordpress.com/2008/01/18/homemade-anodizing/
[13:53:14] <PetefromTn_> whats funny is every single youtube video I have watched does not actually show someone taking the part out of the sealer bath with any sort of clarity
[13:53:16] <_methods> that guy has some after sealer pics
[13:54:22] <PetefromTn_> interesting
[13:54:43] <PetefromTn_> you can sort of see even on his GOOD parts the matte-ish finish I am talking about
[13:54:55] <PetefromTn_> on the tops of the parts in the background
[13:55:04] <_methods> yeah
[13:55:48] <PetefromTn_> also he shows that some of the parts were 2024 and some were 6061
[13:55:53] <archivist> PetefromTn_, where I worked after sealing there was a hand wipe of lanolin on the stuff, but that was for 20-30 year outdoor protection
[13:56:24] <PetefromTn_> he makes the comments that the 2024 parts had a white smut
[13:56:36] <PetefromTn_> if you look closely at that last photo
[13:56:59] <PetefromTn_> you can see the matte look in the holes of the donut shaped parts
[13:57:07] <PetefromTn_> but the outside is shiny
[13:57:20] <PetefromTn_> which makes me think he had the same thing I am talking about
[13:57:28] <PetefromTn_> archivist thanks for that information
[13:58:08] <PetefromTn_> you can actually blow that last photo up and look closer at it
[13:58:16] <archivist> PetefromTn_, it is from a dark memory from 40 odd years ago
[13:58:23] <PetefromTn_> okay
[13:58:49] <furrywolf> lanolin is nice. I have some lanolin spray I use on my hilift jack and other things that would get rusty if left outside, and it works great.
[13:58:59] <PetefromTn_> honestly now that I cleaned the crap out of one of the parts with dawn essentially removing any oils or greases and the part still looks really good I think I am okay

[14:03:27] <archivist> memory was right
http://www.nevilles.co.uk/andoising.htm
[14:20:22] <CaptHindsight> gloss is generally done by bright dipping, it's a level 200 or 300 anodizing class
[14:22:49] <_methods> ahhh
[14:23:04] <CaptHindsight> http://www.potashcorp.com/media/bright_dip_manual.pdf
[14:23:50] <CaptHindsight> When aluminum is placed in a hot Bright Dip solution composed of phosphoric and nitric acids, the
[14:23:50] <CaptHindsight> nitric acid reacts with the aluminum to form an aluminum oxide film. This film is immediately dissolved by the phosphoric acid,
[14:24:22] <CaptHindsight> These reactions occur more rapidly at the peaks than in the valleys because the Bright Dip solution is very viscous. There is less agitation in the valleys than at the peaks; therefore, the rate of the reaction
[14:24:22] <CaptHindsight> in the valleys decreases as the solution becomes saturated with aluminum phosphate and the nitric acid is depleted.

[14:24:57] <CaptHindsight> The surface of an aluminum part can be visualized as a series of “peaks and valleys” or high and low
[14:24:57] <CaptHindsight> areas. For the Bright Dip bath to smooth this surface, there must be a faster rate of attack and more metal removed at the “peaks” than in the “valleys.”

[15:15:25] <PetefromTn_> so is what you are saying is that the matte look after coming out of the sealer bath is typical then? I don't really know what to think other than the fact that after I clean with acetone and wipe with WD40 I get a nice looking part

[15:18:04] <ssi> it's going to revolutionize personal travel
[15:18:10] <ssi> _Sync_: yea :/
[15:18:13] <CaptHindsight> the acetone removes any loose unsealed dye, the WD40 acts as a polish
[15:18:36] <PetefromTn_> CaptHindsight and this is typical process?
[15:19:43] <CaptHindsight> unless they are bright dipped or similar they have a dull finish
[15:19:45] <PetefromTn_> LOL if you watch that video a bit longer (if you can stand it) it looks like the machine is kicking the guy in his ass with every step
[15:20:33] <PetefromTn_> Okay yeah so I am giving these parts a light brushed finish with the 3M scotchbrite wheels and pads so that is definitely not a polished finish look.
[15:21:07] <PetefromTn_> so the finish I am getting right out of the sealer tank is to be expected. Then as I said once I give it a wipe down it looks really nice and smooth/satiny look
[15:21:35] <PetefromTn_> even after I clean it with dawn dishwashing detergent it retains that look almost
[15:21:44] <PetefromTn_> I was just concerned I was doing something wrong here
[15:21:55] <PetefromTn_> I REALLY REALLY appreciate your input Captain.
[15:22:07] <furrywolf> that walking machine, from the ~10 seconds of video that's managed to load, looks surprisingly complicated...
[15:22:20] <ssi> it's not too bad
[15:22:44] <ssi> just a couple five bar linkages driven by a crankshaft
[15:22:48] <furrywolf> in that someone had to work hard to design that linkage
[15:22:48] <PetefromTn_> its just an eccentric mechanism with links

[15:23:14] <ssi> that one
[15:23:20] <furrywolf> it's not "just". you try designing something to get that functional of a gait. :P
[15:23:33] <PetefromTn_> honestly while it is kinda humorous looking the guy put a LOT of hard work into it
[15:23:36] * furrywolf has worked on walking things before, and it ain't easy
[15:23:41] <ssi> I've done it, and I know :P

[15:51:24] <ssi> it was nerve wracking, but pretty awesome looking
[15:51:28] <PetefromTn_> Simonious That looks a lot like another machine I have seen retrofitted
[15:51:42] <Simonious> PetefromTn_: good machine?
[15:51:47] <_methods> they sure don't have many pics of it
[15:51:47] <PetefromTn_> there is a fellow here retrofitting one
[15:51:48] <_methods> hard to tell
[15:52:08] <PetefromTn_> as I understand it they are head and shoulders above any of the cheap chinese machines
[15:52:12] <Simonious> PetefromTn_: why the refit?
[15:52:24] <PetefromTn_> I want to say they are called bench something named?
[15:52:38] <ssi> I imagine if it'll do steel, it'll have to run very very slowly
[15:52:39] <PetefromTn_> apparently he got an older one with a blown control for a low price

[15:53:23] <archivist> Simonious, I can imagine a better price/performance elsewhere, they lack images and the right detail

[15:53:45] <Simonious> archivist: me too, but I'm not sure what particular items would be better price/performance!

[16:01:20] <Connor> Simonious: Tormach 770 or 1100??
[16:01:21] <archivist> like a hackspace? then doing their own retrofit is good experience

[16:04:25] <PetefromTn_> cutting metal finally hehe
[16:07:35] <Simonious> so.. is the tormache a better option than the benchmill? that's my thinking at the moment.
[16:07:41] <Simonious> http://www.tormach.com/store/index.php?app=ecom&ns=catshow&ref=PCNC770_Packages_Ed1
[16:07:49] <ssi> tormach is a pretty solid machine
[16:08:18] <archivist> and some real quality control
[16:08:50] <Simonious> looking to see if it has the 4th axis..
[16:09:01] <PetefromTn_> I would probably personally not get the 770 unless you are making a lot of smaller parts
[16:09:19] <PetefromTn_> it is a smaller machine with higher speed spindle
[16:09:41] <Simonious> PetefromTn_: smaller work area than the benchmill? looking
[16:11:11] <PetefromTn_> if you are considering the Tormach you might also look into the Novakon Torus and the Charter Oak CNC bedmills
[16:11:49] <PetefromTn_> Simonious no I meant that the 770 is smaller than the 1100 from Tormach
[16:11:58] <Simonious> ahh
[16:12:37] <PetefromTn_> All of these are at the top of the chinese bedmill heap really and most have at least decent reputations
[16:13:13] <Simonious> Tormach is a Chinese?
[16:13:13] <PetefromTn_> Tormach has been around awhile and probably has the best reputation and the most available options and tooling but that does not necessarily mean it is the best machine
[16:13:18] <PetefromTn_> yes
[16:13:28] <PetefromTn_> designed and whatnot here and built over there
[16:13:36] <Simonious> oh.. of course
[16:13:59] <ssi> it's a step above chinese mills designed in china and built in china with chinese QC and chinese sellers
[16:14:12] <PetefromTn_> Tormach does seem to employ a large staff and has competent engineers on hand to help with the design and support
[16:14:58] <PetefromTn_> would not be surprised if that INtellitek machine is also made in china but honestly have never seen it before
[16:15:28] <Simonious> probably
[16:15:49] <Simonious> we've got a HAAS in the shop where I work... but I'm not allowed to touch it :P
[16:16:06] <PetefromTn_> I like HAAS machines...have run quite a few now
[16:16:20] <PetefromTn_> they are a great machine for a reasonable price
[16:16:40] <Simonious> My background is 3d printing and router tables.. I'm told I don't have enough machine experience to touch the HAAS yet :P
[16:17:02] <Simonious> (I've designed and built 3d printers though)
[16:17:22] <ssi> 3d printers can't do tens of thousands of dollars to themselves and/or kill employees due to mishandling or misprogramming :)
[16:17:23] <PetefromTn_> well I don't know jack about 3d printing but if you can run a router table programming you can probably run a CNC mill.
[16:17:51] <Simonious> PetefromTn_: I'd need to know something about materials and speeds
[16:17:54] <PetefromTn_> the toolpaths are similar just with different speeds and feeds
[16:17:57] <Simonious> there are certainly a few things I don't know that apply
[16:18:04] <PetefromTn_> sure
[16:18:12] <archivist> sometime on manual machines helps too
[16:18:26] <Simonious> I'm allowed to use the lathe and the bridgeport :)
[16:18:41] <PetefromTn_> and like SSI said accidents on a HAAS machine can be both dangerous and expensive
[16:18:47] * Simonious nods
[16:19:33] <PetefromTn_> I have watched experienced machinists with years of time on VMC's destroy parts and tools and send things flying tho heh
[16:20:01] <Simonious> I've heard stories.. But never seen it.

[17:56:27] <dirty_d> im thinking like, oops i forgot to connect the alligator clip
[17:56:54] <dirty_d> i guess you could limit the damage by having it only probe down like 0.01" at a time

[18:23:58] <skunkworks> something someone hacked together with their path pilot software.
[18:24:16] <skunkworks> linuxcnc under the hood
[18:24:17] <_methods> their machines don't tap?
[18:24:26] <cradek> now they do

[18:27:16] <cradek> hey it's pretty new in linuxcnc too - we've only had it since 2007
[18:27:16] <_methods> yeah lol
[18:27:20] <_methods> you end up with mach4

[18:30:19] <PCW> Pretty sure in mach, synchronized moves beyond simple coordinated axis motion (for Mach with PP) is deferred to the external motion controller
[18:30:54] <_methods> like grbl lol
[18:32:04] <PCW> Well the problem then is you have a nasty environment to write complex real time motion algorithms

[18:38:51] <cradek> it works great
[18:39:19] <skunkworks> that has to make some drool...
[18:40:21] <skunkworks> the competior uses a servo spindle and some sort of pic processor to switch from free running to A axis for rigid tapping in mach. (and you need to program the motion acordingly)

[21:20:50] <JT-Shop> one more shipment to package up and I'm calling it a day
[21:20:57] <JT-Shop> good night
[21:21:03] <greg___> So my garage has two outlets. One is GFCI protected and one isn't..... also should an outlet on the ceiling also be GFCI? it isn't
[21:21:21] -!- Deejay has quit [Quit: bye]

[21:21:56] <_methods> lol
[21:23:19] <SpeedEvil> Lighting going off due to ground faults can be more dangerous than not
[21:24:40] <greg___> and the outlet that has gfci is for some reason connected to the bathroom GFCI above it, so wasn't crazy the day the compressor turned in the garage while my wife was blow drying her hair the breaker popped
[21:25:39] <greg___> panel says that bathroom is on a different circuit
[21:27:33] -!- acdha has quit [Ping timeout: 246 seconds]
[21:27:46] <roycroft> a gfci receptacle protects any other receptacles downstream on the same circuit
[21:28:08] <roycroft> so depending on how your wiring is run, all three of your garage outlets may be protected
[21:31:41] <greg___> I checked, circuit tester doesn't trip GFCI in that outlet
[21:34:35] <JT-Shop> the trip button on the outlet?
[21:35:05] <greg___> no circuit tester has button to check ground fault detection
[21:36:05] <greg___> wires run into the garage to the unprotected box, into the ceiling, back down to the protected one, then into an adjacent bathroom. i have no idea where the upstairs bathroom connects, but it's probably in the first bath. upstairs bath has aGFCI probably because it's supposed to be on a different breaker.
[21:39:01] <greg___> So, to get 240 into the garage i'll removel the non GFCI outlet and put in the 240 receptacle. GFCI breaker will feed that.
[21:42:43] * JT-Shop has never seen a 240v gfci breaker
[21:45:47] <roycroft> you push the test button on the gfci receptacle and it kills the power
[21:46:06] <roycroft> any other receptacles that lose power at that point are also protected
[21:46:42] <roycroft> and i have multiple 250vac gfci breakers in my house
[21:46:53] <roycroft> they are not uncommon
[21:46:58] <roycroft> any spa breaker is going to be gfci
[21:47:21] <roycroft> i installed one for my brew system, as it involves high voltage, high current, and lots of wetness

[21:53:27] <zeeshan> i was looking for you
[21:53:33] <roycroft> brewing is a wet, messy business
[21:53:42] <andypugh> I am working in Granada.
[21:53:48] <zeeshan> granada?
[21:53:52] <SpeedEvil> I only once accidentally brewed.
[21:53:57] <SpeedEvil> I made alcoholic yogurt
[21:54:00] <roycroft> as in spain?
[21:54:03] <andypugh> (Unlike Grenada, you can’t invade Granada)
[21:54:05] <SpeedEvil> It was actually really nice
[21:54:14] <zeeshan> oo its spain
[21:54:19] <zeeshan> what are you doing there
[21:54:22] * roycroft has been to granada
[21:54:24] <andypugh> Working
[21:54:43] <greg___> I was mistaken about the upstairs bath it's separate. I paid 25$ for a seimens 240 GFCI breaker on ebay.
[21:54:51] <andypugh> Granada is hot, and the Sierra Nevada are high, so it’s a good place to test cars
[21:54:55] * roycroft was not working at the time - he was drinking sangra and eating tapas
[21:55:02] <zeeshan> ive heard of sierra nevada
[21:55:34] <roycroft> go visit la alhambra if you haven't already
[21:55:37] <andypugh> In fact, at the top of the mountain today, every car was a prototype, as were all the trucks, and the bus.
[21:55:42] <roycroft> it's a pretty amazing place
[21:55:54] <andypugh> I tried to get Alhambra tickets, none available.
[21:56:06] <zeeshan> andypugh: are you testing fords? :D
[21:56:23] <roycroft> when i was there, in the '70s, trucks would back up some of the high mountain roads, because their reverse gear was lower than their first forward gear
[21:56:43] <andypugh> There were Porsches, BMWs, Mercedes, Renault, Mini and lots of Fords. Plus MAN and Mercedes trucks, and a Mercedes bus.
[21:56:55] <roycroft> no seats?
[21:57:02] <roycroft> seat is/was the spanish national car
[21:57:17] <roycroft> and they were all white

[21:58:05] <zeeshan> how to make this
[21:58:08] <zeeshan> the purple thing
[21:58:12] <zeeshan> right most hole is 1/16

[21:59:00] <andypugh> 3-axis wire spark erosion
[22:00:07] <andypugh> A lathe could probably bore it, but you would need quite a special tool. (little, but long)
[22:01:10] <andypugh> I think I would make a longer holder for a P Horn 105 style boring tool, but if you are buying it in, then wire erosion is more straightforward.
[22:02:57] <andypugh> Wire erosion could only make the purple bit though. A lathe + tooling could make the purple and tan as one part
[22:03:47] <andypugh> Or that beige? Taupe? Camel? Does anyone have access to a girl to ask? :-)
[22:04:09] <PetefromTn_> my wife will be home shortly I will ask her for you hehe
[22:04:43] <greg___> If possible move some of the cone to the orifice part so you don't need as much reach?
[22:06:38] <roycroft> the brown, purple, and gold bits are one part, and all that could be turned on a lathe
[22:06:44] <roycroft> the green is obviously a second part
[22:06:51] <roycroft> since it screws to the brown paret
[22:06:52] <roycroft> part
[22:07:05] <roycroft> and the green part can be turned on a lathe easily

[22:45:54] <andypugh> I think the Holbrook will be stiffer :-)
[22:46:04] <zeeshan> thats a good way to show how dinky the chinese lathe is
[22:46:20] <zeeshan> andypugh: i was arguing with some phd students today
[22:46:29] <zeeshan> tell me if im wrong or not
[22:46:45] <zeeshan> they were stating that the cross head speed of a tesnile tester can be related to strain rate
[22:46:57] <zeeshan> using the equation "strain rate = cross head speed / gage length"
[22:47:18] <zeeshan> that's only true for a certain region
[22:47:40] <zeeshan> you can clearly see in their strain vs time plot
[22:47:46] <zeeshan> there is a linear section and then it becomes non linear
[22:47:54] <andypugh> Well, first you need to be clear on engineering strain and true strain
[22:48:20] <andypugh> Then decide if you are using original gauge length or current gauge length
[22:48:51] <zeeshan> okay lemme describe the scenario a bit better
[22:49:04] <zeeshan> he wants to carry tests out using the tensile tester at 0.001 1/s
[22:49:21] <andypugh> It gets really important with comression tests
[22:49:40] <_methods> man this amazon prime day sale is pretty lame
[22:49:45] <zeeshan> he sets the cross head speed to 0.001 in/s because strain rate = 0.001/1 (his samples are 1" wide)
[22:50:05] <zeeshan> now we get the results from the optical strain measurement system
[22:50:10] <zeeshan> (log strain)
[22:50:13] <zeeshan> aka true strain
[22:51:07] <andypugh> It’s been a while, but I think that speed / original gauge length is engineering strain, and it gets pretty confusing to use for high strains, and especially in compression.
[22:52:01] <andypugh> Compress a specimen to zero length, is that a strain of 1 or infinity?
[22:52:09] <zeeshan> that is engineering strain youre right
[22:52:29] <zeeshan> wow i cant find a strain vs time data online
[22:53:03] <andypugh> Basically the student isn’t wrong. But you are more right :-)
[22:53:20] <zeeshan> http://what-when-how.com/wp-content/uploads/2011/07/tmp1969_thumb.jpg
[22:53:22] <zeeshan> forget the usec
[22:53:28] <zeeshan> his graph looks like that
[22:53:34] <andypugh> If his strains are significant he will find analysis easier if he uses true strain.
[22:53:36] <zeeshan> but the non linear portion on the right keeps on increasing
[22:53:57] <zeeshan> how can he possibly say that strain rate is 0.001 in/s
[22:54:00] <zeeshan> when you can clearly see on the right
[22:54:02] <zeeshan> it changes.
[22:54:42] <andypugh> Well, yes, a time/strain graph at constant strain has to be a straight line
[22:54:50] <zeeshan> EXACTLY!!1
[22:54:55] <zeeshan> i weas trying to explain
[22:54:57] <andypugh> That’s not even engineering, that’s basic maths
[22:54:59] <zeeshan> you can't EVER get constant strain
[22:55:02] <zeeshan> rate
[22:55:12] <zeeshan> WITHOUT feedback from an extensometer
[22:55:34] <zeeshan> the controller needs to know incremental strain always
[22:55:39] <zeeshan> to be able to control strain rate
[22:55:50] <andypugh> For a known sample length you can do it with a cam. And at 100/second too :-)
[22:56:03] <zeeshan> camera? :D
[22:56:23] <andypugh> Actually, I think I got to 1000/sec before the machine dismantled itself.
[22:56:25] <zeeshan> the zwick optical extensometer works like that
[22:56:35] <zeeshan> it tracks 2 dots or lines on a sample
[22:56:39] <zeeshan> to get incremental strain
[22:56:42] <zeeshan> and also provides feedback
[22:56:47] <andypugh> (0 to 50mph on 5mm)
[22:56:53] <zeeshan> also i was trying to explain to him

[22:57:13] <zeeshan> this one other student i know whos frustrating me because i need uniaxial data for my smp film

[22:58:30] <zeeshan> so you dont have compliance of the machine causing errors in your measurement?
[22:59:03] <andypugh> I have used crosshead a lot.
[22:59:46] <zeeshan> so its okay to use the cross head displacement to get strain?
[22:59:49] <andypugh> You need to be sure it’s a stiff machine, and the gauge length needs to be a lot smaller than the rest of the sample. it’s often good enough for cylindrical test pieces.
[23:00:12] <andypugh> I wouldn’t choose to use it for strip specimens.
[23:00:13] <zeeshan> what do you mean the gauge length needs to be smaller
[23:00:16] <zeeshan> okay
[23:00:20] <zeeshan> he's been using strip speciments
[23:00:22] <zeeshan> not dogbone
[23:00:45] <zeeshan> youre basically saying you need a reduced cross section
[23:00:49] <andypugh> Hmm, I was meaning Dogbone when I said strip.
[23:01:54] <andypugh> With a specimen turned on a lathe the gauge length is at most 50% the CSA of the grip portion, and often a lot less. You can be fairly confident that most of the strain is in the gauge length.
[23:01:59] <zeeshan> we're working with films
[23:02:03] <zeeshan> so the samples are flat
[23:02:34] <andypugh> If the samples are flat and parallel, then actually cross-head is likely to be very close to accurate.
[23:03:00] <andypugh> if they are not parallel (ie, waisted) then you need to look at how much strain is in the grip portions.
[23:03:21] <andypugh> A quick and dirty FEA analysis might be in order.
[23:04:09] <zeeshan> when you can use dic to get true strain
[23:04:13] <zeeshan> you pretty much are measuring the real deal
[23:04:18] <zeeshan> without exterior effects
[23:04:33] <andypugh> The problem with flat/parallel is the extra constaint laterally from the grips. So the strian state near the grips is complex
[23:04:49] <zeeshan> the senior reseach engineer there says there is a singificant difference between measuring using cross head displacement
[23:04:52] <zeeshan> vs dic
[23:05:18] <zeeshan> he says that if cross head displacement is 4mm, the dic reports 2mm
[23:05:26] <zeeshan> i don't know who to trust lol
[23:05:44] <andypugh> Yes, the only reason I didn’t use extensometers was because they were terribly expensive :-)
[23:06:33] <zeeshan> i don't get some people
[23:06:37] <zeeshan> when we have the equipment
[23:06:41] <andypugh> Well, if the extensometer is only measiring half the gauge length of the crosshead, both are true
[23:06:45] <zeeshan> why would you make a choice to use an ancient technology?
[23:07:07] <andypugh> I rise a 1921 motorcycle, I might not be the best one to ask.
[23:07:13] <zeeshan> haha
[23:07:50] <andypugh> Anyway, I do need to sleep. I am on euro-time now
[23:07:55] <zeeshan> gnite!

[23:39:06] <Valen> whats the difference between a drawbar and pull stud?
[23:41:50] <skunkworks> might overlap... But normally a draw bar screws into the tool holder too retain it into the spindle. Pull stud is on the tool holder and is used to pull the tool into the spindle
[23:42:37] <Valen> that's what I figured
