[00:28:47] <ssi> hi
[00:28:58] <ssi> I don't like odd numbers
[00:31:19] <andypugh> Odd numbers are the best, especially primes.
[00:32:51] <Tom_itx> what's andy been up to?

[00:38:32] <andypugh> Tom_itx: Today I was mainly making an adaptor so that I can screw my M33 chucks onto the 1 1/8 x 16 nose of my dividing head.
[00:39:54] <andypugh> And then I will be making a large batch of face-clutch nuts and gears for the foot-starter of the Ner-a-Car: http://youtu.be/86MN3CN7Aiw?list=UUexvgsGz_QFvOublovDYoTQ
[00:40:18] <cathode> sometimes i wonder if maybe we'll finally convert to metric in the USA in the next 20 years or so... we have a generation of kids growing up that are routinely exposed to metric in videogames
[00:40:36] <roycroft> convert for the third time, you mean?
[00:41:17] <cathode> lol
[00:41:20] <cathode> sure
[00:41:23] <andypugh> Given that the units are arbitrary, but the maths gets easier, the only reasons not to are expense.
[00:41:40] <cathode> the units aren't really arbitrary
[00:42:06] <roycroft> we only conver to si units in the '70s
[00:42:08] <roycroft> convert
[00:42:14] <roycroft> so we have about 60 years go to before we do it again
[00:42:30] <andypugh> The UK only changed when we realised that we were not the world’s biggest manufacturer any more. Perhaps when the US realsies the same thing, and that they don’t get to make their own rules any more/
[00:42:45] -!- rob_h has quit [Ping timeout: 256 seconds]
[00:42:48] <zeeshan> whats wrong with imperial units?
[00:43:01] <roycroft> nobody uses them, for one thing
[00:43:08] <zeeshan> ??
[00:43:18] <andypugh> Nothing is _wrong_ with them, but the stupidly varying number bases is silly.
[00:43:19] <roycroft> we use american customary units
[00:43:19] <zeeshan> tons of industry uses em
[00:43:23] <roycroft> not imperial
[00:43:30] <zeeshan> it's really not hard to convert between both systems
[00:43:33] <zeeshan> dont complain :P
[00:44:02] <cathode> i would be happy if i could say "it's 1.5 meters long" and the person i was talking to would at least have an idea of what that meant
[00:44:21] <roycroft> andypugh: we have the added problem of being even more jingoistic and xenophobic than the brits
[00:44:34] <andypugh> decimal inches to mm is trivial. Feet and fractional inches less so.
[00:44:34] <zeeshan> i understand feet more than m
[00:44:40] <zeeshan> north american stock is in feet.
[00:44:41] <zeeshan> not meters
[00:44:44] <Tom_itx> andypugh there must be a shortage of those parts?
[00:44:51] <zeeshan> 2.54
[00:44:52] <zeeshan> 25.4
[00:44:53] <roycroft> you understand yards, don't you?
[00:44:57] <zeeshan> not hard to understand :P
[00:45:02] <Tom_itx> i thought you were done with that project...
[00:45:06] <zeeshan> roycroft: its close to 100m
[00:45:09] <roycroft> yards/meters are almost the same for small measurements
[00:45:09] <zeeshan> so yea i understand
[00:45:28] <zeeshan> i like both systems
[00:45:29] <andypugh> Tom_itx: Soon there won’t be. I am making more parts than there are vehicles for them extant (well, not really)
[00:45:37] <andypugh> I dont
[00:45:43] <roycroft> the inches to feet to miles things are weird
[00:46:04] <roycroft> but for some things, fractional units are nicer to use than decimals
[00:46:07] <andypugh> I don’t actually need these parts, mine are fine. This was an order from folk on a maling list.
[00:46:15] <zeeshan> i like fractions too :D
[00:46:21] <andypugh> I hate them.
[00:46:24] <cathode> so, i noticed that Matthias Wandel uses 'thous' (thousands of an inch) but metric measurements for everything else
[00:46:44] <cathode> are thous a common measurement for really small things in europe, too?
[00:46:46] <andypugh> I guess in thou. I measure in mm.
[00:46:50] <cathode> or is that a Canadian thing?
[00:46:55] <roycroft> i don't say anything here, or most places, about this, because it's so prevelant and not worth making a stink about
[00:46:57] <zeeshan> matthias is sweidhs
[00:47:06] <zeeshan> and micron and thou are very common
[00:47:08] <roycroft> but i absolutely hate the term "thou"
[00:47:08] <zeeshan> ive heard boith
[00:47:17] <zeeshan> why roycroft
[00:47:21] <roycroft> it makes me cringe every time i see someone spell it out or say it
[00:47:24] <zeeshan> its short for thousandths
[00:47:26] <cathode> thou
[00:47:28] <andypugh> “thou” is less confusing than “mil”
[00:47:34] <roycroft> thousandths is just fine
[00:47:36] <zeeshan> mil should be eliminated
[00:47:42] <roycroft> thou just sounds stupid to me
[00:47:44] <zeeshan> you're not gonna keep repeating thousandths! :P
[00:47:48] <zeeshan> thou is much faster
[00:47:53] <andypugh> Yeah, milli-inch is mixing your systems.
[00:47:55] <roycroft> i can't give a rational reason why i dislike it so much
[00:48:00] <Tom_itx> or tenths
[00:48:06] <roycroft> see
[00:48:12] <roycroft> for some reason, "tenth" doesn't bother me
[00:48:19] <roycroft> as short for "ten thousandth"
[00:48:22] <zeeshan> both systems are great :P
[00:48:29] <zeeshan> if i really wanna be picky
[00:48:34] <zeeshan> i can pick on 'newton'
[00:48:42] <roycroft> and no, i really won't bother trying to explain why, because i can't
[00:48:46] <andypugh> I liked “teenths” as a unit. Ok, so it was sixteenths of an ounce of something :-)
[00:48:48] <roycroft> it just bugs me
[00:48:59] <roycroft> but i will probably never say anything about it again
[00:48:59] <zeeshan> in uk is your standard stock in mm
[00:49:01] <zeeshan> or inches
[00:49:05] <cathode> one of the reasons i'd like to have digital controls on certain things that are otherwise manual, like my table saw fence, is that i want to be able to specify or have a readout in both number systems
[00:49:07] <zeeshan> cause ive been thinking its in mm
[00:49:21] <zeeshan> like can you buy 2x1/2" flat bar? :p
[00:49:37] <andypugh> zeeshan: We tend to buy 2.7 m lengths of 3x2 wood :-)
[00:49:43] <cathode> lol
[00:49:49] <zeeshan> or would it be 51 x 13 mm flat bar?
[00:50:03] <zeeshan> haha
[00:50:22] <andypugh> It depends, have a look: http://www.metals4u.co.uk
[00:50:23] <Tom_itx> we should all go back to wentworth
[00:50:30] -!- mightym has quit [Read error: Connection reset by peer]
[00:50:35] <cathode> when you get to computer hardware it gets REALLY funky. fans are measured in mm, but other things are in inches. and 2.5" hard drives use M3 screws, but 3.5" hard drives use #6-32 screws
[00:50:45] <zeeshan> haha
[00:50:46] <zeeshan> i knew it!
[00:50:50] <zeeshan> flat bar is in mm there!
[00:50:59] <zeeshan> 50x12
[00:51:07] -!- Valen has quit [Quit: Leaving.]
[00:51:10] <andypugh> Tube comes in both.
[00:51:11] <cathode> a 19" server rack has inch spacing between the mounting holes, but the front-to-back distance is measured in mm
[00:51:23] <zeeshan> tube is an exception though :P
[00:51:26] * cathode throws hands up
[00:51:47] <andypugh> Metric pipe threads are Imperial, and whitworth thread-form..
[00:51:47] <roycroft> tube is a strange word
[00:51:54] <Connor> cathode: And don't forget the bolts. ones with tapped holes are one thing.. ones that use cage nuts use different size..
[00:52:04] <cathode> yeah
[00:52:06] <Connor> on 19" racks
[00:52:15] <cathode> i use all M6 cage nuts on my rack
[00:52:28] <cathode> unless i have to use something else (like captive screws that are 10-32)
[00:52:42] <cathode> ....which means i *still* have to stock other sizes of cage nuts
[00:52:49] <zeeshan> this metal4u place
[00:52:52] <zeeshan> is nice
[00:52:56] <zeeshan> they seem to have everything
[00:53:17] <Connor> http://www.speedymetals.com/
[00:53:26] <Connor> is were I get my metal online from.
[00:53:27] <cathode> i ordered my shaft material from speedy
[00:53:28] <andypugh> All the aluminium round at metals4u is inches, interestingly
[00:53:41] <roycroft> don't you still use bsp for your plumbing?
[00:53:42] <cathode> it was inexpensive and good quality
[00:53:43] <zeeshan> connor no local supplier?
[00:53:51] <zeeshan> ordering metal online seems expensive :P
[00:54:04] <Connor> Yes.. but.. only for shorts and cut off scrap they have..
[00:54:06] <zeeshan> if i order more than 2000
[00:54:07] <zeeshan> they'll deliver
[00:54:15] <roycroft> if you don't have a local metal purveyor ordering it online can be cheaper
[00:54:44] <roycroft> but the solution to that problem is to live in a place with a metals purveyor
[00:55:01] <cathode> zeeshan - i only needed two 1ft peices of 1-1/4" steel shaft, shipping was like $15 or so, and the shaft was $12/ft (i think?)... most of the local places won't sell to hobbyists
[00:55:23] <andypugh> BSP is the ISO standard for threaded pipe. But soldered copper plumbing is OD-sized at 8, 10, 15, 22, 38mm. (15 and 22 by far the most commonin the UK, 10 and 15 on mainland Europe where they typically use higher water pressure.
[00:55:25] <cathode> like, you have to have a contractor license or a business account with them
[00:55:42] <zeeshan> cathode: wow that sucks
[00:55:50] <andypugh> I tend to get most of my metal from eBay.
[00:55:52] <cathode> and often times there's minimum orders
[00:55:59] <zeeshan> well im from steel city
[00:56:11] <zeeshan> i have like 6 stores that retail
[00:56:17] <zeeshan> and wholesales need minimum 200
[00:56:17] <andypugh> Unless I am in a hurry and can face buying a 3m length,
[00:56:46] <roycroft> i tend to buy 10' lengths of metal, even when i only need a short piece
[00:56:51] <andypugh> I bought some box section, it came as a 7m length. I had to drag it into the street to unwrap it.
[00:57:02] <roycroft> exceptions being for ss, brass, and other expensive metals
[00:57:13] <roycroft> i can buy by the foot, but cut costs are high
[00:57:21] <roycroft> and i see it as a way to slowly build inventory
[00:57:41] <cathode> i already have too much crap in my basement. heh
[00:57:48] <cathode> storage isn't free
[00:58:40] <zeeshan> price per length (20 footer)
[00:58:42] <zeeshan> is so cheap
[00:58:49] <zeeshan> for flatbar fro example
[00:58:56] <zeeshan> ie $30
[00:59:00] <zeeshan> vs paying 22 bux for 10 feet
[00:59:00] <zeeshan> lol
[00:59:21] <andypugh> I recently found that “E J Alloys” not so far from me don’t just do alloys. They sold me some phosphor-bronze sheet (I didn’t even know it existed) and I noticed that they had steel in stock as well as plastics. Best of all, open 11am to 4pm on Saturdays.
[00:59:30] -!- dnaleromj has quit [Ping timeout: 265 seconds]
[00:59:46] <cathode> phosphor-bronze sheet??
[00:59:52] <cathode> what did you use that for btw
[01:02:13] <cathode> in other news... whats the chances that these are going to be total garbage? http://www.ebay.com/itm/331273587914?_trksid=p2060778.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT
[01:02:29] <andypugh> cathode: The contacts of a replica one of these: http://www.geutskens.eu/neracar/lighting_switch.htm
[01:02:33] <zeeshan> those look like wood cutting saws
[01:02:39] <cathode> they're for metal
[01:02:45] <andypugh> It should be spring-temper copper, but that’s hard to find nowadays.
[01:03:34] <andypugh> cathode: If they are really Bosch, and bi-metal, they shoiuld be pretty good.
[01:03:52] <cathode> zeeshan - you can tell it's for metal because the teeth are slightly splayed out to either side... wood blades don't have that
[01:04:02] <cathode> andypugh - ok. i ordered 30 of them :P
[01:04:06] <zeeshan> theyre way too coarse
[01:04:07] <zeeshan> for metal
[01:04:23] <zeeshan> metal ones are at least 22 tpi
[01:04:29] <cathode> i need to cut some 3" x 3.5" x 5/16" L-channel
[01:04:42] <andypugh> That depends on how thick the metal is.
[01:04:43] <zeeshan> if its aluminum
[01:04:45] <cathode> 14tpi was reccomended all over for thicker metal (over 1/8")
[01:04:46] <zeeshan> you'll be fine
[01:04:54] <cathode> it's mild steel
[01:05:12] -!- SpeedEvil has quit [Quit: No Ping reply in 180 seconds.]
[01:05:13] <zeeshan> basically the rule of thumb is
[01:05:16] <zeeshan> 3 teeth in contact
[01:05:20] <zeeshan> at all times of cutting action
[01:05:36] <andypugh> At $0.25 each you can’t go far wrong if it’s a quick-release blade holder :-)

[01:05:42] <zeeshan> haha
[01:05:46] <cathode> i should have clarified, i didn't get 30 of the same, i got a pack of the 14, a pack of 24tpi, and another pack of 14 that were bosch but a different "series"
[01:06:33] <cathode> i also got a two-pack of Hitachi 18tpi blades for cutting stainless steel
[01:06:37] <cathode> was $4.50
[01:07:31] <cathode> they're shipping from Boise, Idaho, i'm in Portland, Oregon... i might get them tomorrow. i'll report back if they're any good :P
[01:09:00] <Connor> Looking for some sort of fitting for a enclosure to pass wires in / out of said enclosure..
[01:09:11] <Connor> doesn't have to be waterproof..
[01:09:14] <cathode> Connor - grommet?
[01:09:33] <zeeshan> anti chaff?
[01:10:01] <Connor> Multiple wires.. not sure a grommet would work.. yea.. anti chaff and strain relief.
[01:10:03] <cathode> i have some rubber grommets that i used for passing ethernet cabling into an enclosure.
[01:10:13] <cathode> ah
[01:10:18] <cathode> strain relief
[01:10:19] <zeeshan> o strain relief
[01:10:31] <cathode> that's an entirely different kind of fitting :P
[01:11:16] <cathode> often times i find it's easier to just fasten the cable on the outside of the enclosure right near the point of entry
[01:11:44] <zeeshan> http://www.contractcleanersupplies.com/Merchant5/graphics/electrical/romex-wire-clamp-connector.gif
[01:11:47] <zeeshan> grab that from home depot!

[01:13:30] <zeeshan> why a re they awful?
[01:13:38] <zeeshan> theyre 2 bux a pop
[01:13:39] <zeeshan> and work
[01:14:02] <cathode> 2 bux a pop? wat. i buy them by the box of 100 and it's like $9
[01:14:03] <cathode> lol
[01:14:38] <cathode> they don't do a good job unless they're tightened so much that you feel like the cable is being damaged. i don't know that they'd work well for a bundle of smaller wires
[01:14:51] -!- PCW has quit [Remote host closed the connection]
[01:15:18] <zeeshan> theyre like 2 bux for 5
[01:15:22] <zeeshan> if you buy in small quantity
[01:15:42] <zeeshan> shrug
[01:15:42] <cathode> ah yea
[01:15:44] <zeeshan> worked for me
[01:16:46] <Connor> Just counted.. Looks like 5 -- 4 conductor, probably 18 gauge.. similar to what I used for steppers.. stranded alarm wire. and then 3 -- 2 conductor, probably 20 or 22 gauge stranded alarm wire..
[01:17:00] <Connor> I've got samples, So I can bundle that up and see how big I need.
[01:17:40] <Connor> I can always ziptie the bundle inside for a strain relief I guess. The box is plastic...
[01:17:54] <cathode> heh i love browsing the 'materials' section on my local craigslist. i don't even know what this thing does but it looks cool. http://portland.craigslist.org/mlt/mat/4730383997.html
[01:18:02] <Connor> but, I think it would be better looking and more professional with some sort of bulk head hole breach.

[01:20:24] <cathode> i should go stock up... wow. http://portland.craigslist.org/wsc/mad/4683604389.html

[01:20:58] <cathode> hmm, XXCoder isn't around
[01:21:06] <cathode> he was looking for 80/20 yesterday
[01:22:15] <roycroft> oh geeze
[01:22:21] <roycroft> i might have to make a run up to pdx tomorrow
[01:22:40] <cathode> oh yeah you're in salem right?

[01:57:34] <ssi> done with what? :P
[01:57:34] <andypugh> cathode: The line reactor is a filter for 3-phase on a motor drive. Very CNC-relevant.
[01:58:20] <XXCoder> fine tuning your lazer machine
[02:01:10] <ssi> oh I'm not fine tuning it
[02:01:13] <ssi> it's in full production mode now
[02:03:48] <XXCoder> oh
[02:03:51] <XXCoder> cool :)

[02:07:20] <zeeshan> anyone know which way
[02:07:25] <zeeshan> a hydraulic pump is supposed to rotate?
[02:07:33] <zeeshan> i found a random arrow on the power pack
[02:07:38] <zeeshan> im assuming that direction? :p
[02:07:42] <zeeshan> cause that'd mean counterclockwise..
[02:08:43] <PetefromTn_> WooHHOOOOoooo
[02:08:55] <PetefromTn_> Tomorrow we are ROAD TRIPPIN'
[02:09:18] <PetefromTn_> my daughter heard we were going to pickup my new to me CNC lathe
[02:09:36] <PetefromTn_> so she offered to let me use her huge F350 Diesel Dually
[02:09:45] <Connor> Nice. SSI coming ?
[02:09:57] <PetefromTn_> should get a bit better mileage than my Fullsize Bronco since its a diesel
[02:10:14] <PetefromTn_> no he has to shoot his laser beam all weekend.
[02:10:21] <Connor> ROFL
[02:10:33] <ssi> I wish I could
[02:10:43] <ssi> but I promised them 5000 parts by the weekend-end
[02:10:44] <PetefromTn_> I got a trailer reserved at UHAUL for tomorrow morning.
[02:11:10] <PetefromTn_> I wonder what kinda mileage we will get with the truck and trailer towing the machine.
[02:11:14] <Connor> What happened to using the neighbors?
[02:11:23] <os1r1s> PetefromTn_: 10-12 MPG
[02:11:31] <PetefromTn_> She said she gets like 20 MPG apparently unloaded
[02:11:31] -!- SpeedEvil has quit [Quit: No Ping reply in 180 seconds.]
[02:11:40] <ssi> it'll be the same loaded
[02:11:40] <os1r1s> Closer to 12 likely
[02:11:47] <ssi> nah bs
[02:11:54] -!- SpeedEvil [SpeedEvil!~quassel@tor/regular/SpeedEvil] has joined #linuxcnc
[02:11:56] <Connor> tarp it to help wind resistance.
[02:12:03] <ssi> two years ago I drove a '96 F250 diesel to connecticut and back and got 23 on the way up and 21 on the way back
[02:12:05] <andypugh> You mean that even your diesels are raping the planet in the US?
[02:12:07] <os1r1s> PetefromTn_: I have a 2012 F350 Diesel. With 6000 lbs behind it I get about 10-12
[02:12:13] <ssi> pulling an empty trailer on the way up and a 4500lb on the trailer on the way back
[02:12:29] <PetefromTn_> I am getting my 10klb tie downs and some tools ready
[02:12:30] <ssi> andypugh: my diesel gets 60mpg
[02:12:46] <PetefromTn_> 6000 pounds of what?
[02:12:52] <os1r1s> PetefromTn_: Race car + trailer
[02:13:12] <zeeshan> os1r1s: what car? :D
[02:13:13] <PetefromTn_> well we are going 260 miles round each way
[02:13:27] <os1r1s> zeeshan: Porsche CaymanS
[02:13:32] <zeeshan> nice
[02:13:33] <zeeshan> :)
[02:13:42] <PetefromTn_> so 520 miles or so
[02:13:45] <andypugh> I expect about 45 cruising at 80 in a work car, I can’t see it going below 30 even with a triailer.
[02:14:10] <PetefromTn_> I am hoping to spend like $130-$150 in gas....
[02:14:17] <PetefromTn_> diesel
[02:14:19] <zeeshan> i was getting 22 L/ 100 km
[02:14:21] <ssi> hopefully you'll spend $0 in gas :P
[02:14:22] <zeeshan> with the big ass flat bed truck
[02:14:23] <andypugh> I have no idea what they do to US cars to make them drink so much fuel.
[02:14:31] <ssi> andypugh: it's the emissions laws
[02:14:38] <zeeshan> andypugh: they dont have you programming the control systems :-)
[02:14:41] <ssi> andypugh: tuning for best emissions is nowhere close to best economy
[02:14:47] <PetefromTn_> how the hell will I spend $0?
[02:14:51] <ssi> PetefromTn_: in gas
[02:14:56] <PetefromTn_> ah
[02:15:23] <os1r1s> zeeshan: With my old truck (before I got the diesel) towing the trailer + car. http://mounicou.com/misc/racetow.jpg
[02:15:32] <PetefromTn_> that truck of hers is a beast...
[02:15:32] <andypugh> Yeah, I am in a position to be puzzled, I work for a US company on diesel engines. I have no idea how the same company can do things so differently.
[02:15:39] <zeeshan> os1r1s: looking good man
[02:15:46] <zeeshan> i drive my baby right to the track
[02:15:46] <zeeshan> haha
[02:15:55] <zeeshan> when its running that is
[02:16:07] <ssi> andypugh: also a 6 or 7 liter diesel engine isn't going to get 50+ no matter what you do
[02:16:08] <os1r1s> PetefromTn_: This is my truck ... Not a dually though ... http://mounicou.com/misc/truck.jpg
[02:16:21] <os1r1s> With a very light load
[02:16:26] <ssi> andypugh: my 2 liter diesel breaks 60mpg easily
[02:16:35] <andypugh> How much power does that 7 litre engine make?
[02:16:40] <PetefromTn_> yeah hers is a dually crew cab diesel.
[02:17:04] <os1r1s> andypugh: The 6.7 in mine makes 550hp and 1000 ft/lb of torque (its chipped)
[02:17:19] <XXCoder> my future "car": elio
[02:17:20] <ssi> andypugh: quick google suggests 275hp/525lbft is the factory numbers on the 7.3 turbo
[02:17:23] <PetefromTn_> My Bronco can actaully easily tow it and I was going to use it but I figure her truck is much newer and since it is a diesel should get much better mileage...
[02:17:32] <ssi> PetefromTn_: yeah that's wise
[02:18:20] <PetefromTn_> hopefully we will be back here by 6 or 7PM with the new machine and smiles on our faces LOL
[02:18:25] <ssi> hope so!
[02:18:29] <os1r1s> PetefromTn_: Where are you headed to get it?
[02:18:32] <PetefromTn_> then we can work on how to get that bitch off the trailer..
[02:18:35] <PetefromTn_> LOL
[02:18:40] <andypugh> Hmm, the 2-litre I work on is 180hp and 300 lb.ft.
[02:18:42] <PetefromTn_> Kentuckeeeee.
[02:19:18] <ssi> andypugh: my 2l is 140hp and 236lbft factory, but again that's an emissions tune, and by getting rid of the particulate filter and doing a power/economy tune it's like 186/300 and picks up 5-7mpg
[02:19:23] <PetefromTn_> Since my daughter is going with me my wife and kids and her husband are going to chill out at the house...
[02:19:25] <andypugh> But typically, at crusing speed, both vehicles will be making about 60hp
[02:19:39] <os1r1s> Cool. I'm still looking for an emco compact pc lathe. Can only do the small stuff.
[02:19:45] <ssi> nah, big trucks have the drag coefficient of a freight train
[02:19:54] <ssi> not to mention horribly inefficient tires
[02:20:02] <XXCoder> get a elio ssi. well when tis out anyway
[02:20:09] <ssi> and gearing ill suited to economy
[02:20:16] <ssi> XXCoder: no thanks.
[02:20:24] <XXCoder> no 84 mpg for you then
[02:20:27] <os1r1s> PetefromTn_: If hers has DEF fluid, make sure it has enough. Really sucks to run low/out.
[02:20:34] <andypugh> That might be the problem, buying a car to move the heaviest thing you can ever imagine moving, then spending 99% of the time moving only yourself.
[02:20:52] <XXCoder> andy thats why im getting elio. for one person moving days'
[02:21:01] <ssi> XXCoder: I'm happy with 60mpg and a real car
[02:21:10] <zeeshan> os1r1s: LOL
[02:21:15] <zeeshan> my flatbed truck rental broke down
[02:21:16] <XXCoder> nice. im stuck budget wise
[02:21:19] <zeeshan> cause DEF was contaminated
[02:21:21] <XXCoder> so elio for me
[02:21:26] <ssi> andypugh: agreed, but when you need a truck, you need a truck
[02:21:32] <os1r1s> zeeshan: Seriously. It limits you to 55. It blows.
[02:21:35] <zeeshan> dude
[02:21:35] <andypugh> So rent one, that day..
[02:21:37] <XXCoder> its just $6,800
[02:21:38] <zeeshan> 5mph!
[02:21:40] <zeeshan> after 30 minutes.
[02:21:48] <ssi> 'course, I bought a 5klb forklift to move the heaviest thing I could ever imagine moving, then I bought a 9000lb vmc :(
[02:21:51] <zeeshan> 50% torque imemdiately
[02:21:54] <PetefromTn_> http://cdn-w.v12soft.com/photos/gin1FGK/239351/b9DJN_640480.jpg Thats what her truck looks like
[02:21:57] <zeeshan> and 30 mins later 5mph.
[02:21:59] <ssi> andypugh: it's not as simple as that I've found
[02:22:11] <zeeshan> the truck had to be towed
[02:22:23] <XXCoder> I'll buy a truck as soon as I turn tea pariter heh
[02:22:26] <andypugh> Hey, what do I know, I have never even owned a car.
[02:22:33] <ssi> just a neracar?
[02:22:48] <XXCoder> bicycle
[02:22:50] <zeeshan> you all should buy electric cars
[02:22:56] <zeeshan> since youre gas saving hippies
[02:22:58] <ssi> no thanks
[02:23:01] <andypugh> The Ner-a-Car and other bikes. When I need a van or a truck I rent one.
[02:23:04] <zeeshan> and leave the gas for me
[02:23:05] <ssi> I'm no gas saving hippy
[02:23:07] <XXCoder> zeeshan: electric car blows as long as battery sucks
[02:23:10] <ssi> I'm a money saving capitalist
[02:23:20] <zeeshan> buy electric!!!
[02:23:21] <zeeshan> leave gas for me
[02:23:22] <zeeshan> :[
[02:23:28] <ssi> I took an 8000 mile road trip this year on $600 fuel
[02:23:30] <XXCoder> zeeshan: buy a elio then
[02:23:44] <zeeshan> i rather spend 6000 on fuel
[02:23:50] <zeeshan> and have fun during those 8000 miles
[02:23:52] <zeeshan> but thats just me :P
[02:24:04] <ssi> I had plenty of fun, not screwing around with some bullshit breaking down racecar
[02:24:08] <ssi> been there, done that
[02:24:10] <ssi> I'm too old for that now
[02:24:20] <ssi> if I'm gonna burn thousands of dollars in fuel, it's gonna be above 200mph
[02:24:20] <zeeshan> build your car right!
[02:24:21] <zeeshan> :P
[02:24:21] <andypugh> Elio looks a bit like the Twizy. We have a Twizy at work, I have been tempted to see who I need to talk to to borrow it.
[02:24:30] <PetefromTn_> Man not looking forward to that long drive tho
[02:24:32] <XXCoder> heh I calculated gas - even with double gas price (half goes to car payment) I still pay pover $200 less gas
[02:24:52] -!- anth0ny has quit [Client Quit]
[02:25:01] <ssi> I can go 200mph for less gas per mile than your racecar can go 100mph
[02:25:04] <XXCoder> but if you live at one of those 5 states you'll have to wear helmet in elio. weird. glad my state isnt one of em
[02:25:26] <zeeshan> ssi yea its called an airplane
[02:25:27] <zeeshan> duhh
[02:25:35] <XXCoder> rocketcar
[02:25:36] <PetefromTn_> I am excited about the lathe tho. I have wanted a decent CNC lathe for awhile now and I can get back into retrofit mode here.
[02:25:37] <ssi> yeah, but most airplanes aren't nearly as fuel efficient
[02:25:43] <ssi> this one's pushing 25mpg
[02:25:44] <ssi> at 200mph
[02:25:47] <ssi> which is insane
[02:25:48] <XXCoder> cornering sucks but 1,000 mph
[02:25:51] <zeeshan> thats pretty good!
[02:26:13] <ssi> my cherokee is like 14mpg at 140mph
[02:26:29] <zeeshan> i dont think even my subie daily driver
[02:26:43] <zeeshan> gets 25 mpg more than 100 mph
[02:26:43] <zeeshan> lol
[02:26:48] <ssi> probably not
[02:26:52] <zeeshan> it does like 28 mpg
[02:26:53] <ssi> it's rich as crap there :P
[02:26:57] <XXCoder> my tardis van is normally 21 mpg but lately 17 mpg, I plan to do tuneup soon
[02:26:58] <zeeshan> at 70 mph
[02:27:08] <ssi> drag coefficient is important :P
[02:27:22] <zeeshan> its sad that the rx7 has a lower cd
[02:27:25] <zeeshan> in comparison to the wrx
[02:27:28] <PetefromTn_> my Bronco gets like six.......Right thru the trees LOL
[02:27:28] <ssi> my diesel vw has a drag coefficient of .29
[02:27:28] <zeeshan> and its 25 years old
[02:27:30] <zeeshan> or more
[02:27:42] <XXCoder> diesel trucks is immortal
[02:27:45] <ssi> rx7 is a decently slippery car
[02:27:47] <XXCoder> not literallt
[02:27:48] <andypugh> Yes, I am sure my bike would do a lot more mpg without the parachute of a rider on top.
[02:27:49] <ssi> wrx is a brick
[02:27:58] <zeeshan> 2d vs 4 door
[02:27:58] <zeeshan> i guess
[02:28:05] <ssi> andypugh: yeah bikes are efficient up to 60mph or so then they suck
[02:28:27] <XXCoder> andypugh: ever seen mythbuster one about bicycle?

[02:31:03] <ssi> yep
[02:31:17] <zeeshan> ive never ever worked on a hydraulic power pack before
[02:31:19] <zeeshan> so this is a first :/
[02:31:21] <zeeshan> lots of brake work
[02:31:23] <zeeshan> never this shit
[02:31:42] <zeeshan> if i dont report back in 30 min
[02:31:43] <zeeshan> call 911
[02:31:44] <zeeshan> :-)

[02:32:43] <zeeshan> which shook the room above it
[02:32:47] <zeeshan> she came running down
[02:32:50] <ssi> lol I told my friend charles in california that I was working on the laser power supply, and if he didn't hear from me to have s omeone come keep the dogs from eating my body
[02:32:52] <zeeshan> goddamn air hole exploded
[02:33:08] <zeeshan> LOL
[02:33:25] <ssi> the laser power supply is one of the few things in my shop that actually scares me a bit :P
[02:33:39] <zeeshan> i think we're all pretty safe when we work on shit
[02:33:43] <zeeshan> the stuff that drives me insane
[02:33:44] <XXCoder> andy thats cool. I like elio better ehh
[02:33:45] <XXCoder> heh
[02:33:51] <zeeshan> is when people get under the car with a hydraulic jack only
[02:34:00] <zeeshan> theres been 3 deaths in this city in the last 4 years
[02:34:01] <ssi> yeah I don't like that
[02:34:02] <zeeshan> so stupid..
[02:34:12] <andypugh> I built a 700V DC PSU, (delon doubler, bit caps, 240V mains) and dismantled it immediately as too scary.
[02:34:17] <ssi> these days I'm lazy and I use drive-up ramps if i need to get under the car
[02:34:29] <zeeshan> what the heck do you need a 700V supply for
[02:34:29] <zeeshan> :D
[02:34:38] <ssi> andypugh: even 700VDC doesn't bother me too much; I like to build tube amps
[02:34:44] <ssi> andypugh: the laser supply is 35kV @ 40mA
[02:34:46] <zeeshan> usually if the wheels are off
[02:34:49] <zeeshan> ill throw em under the car
[02:34:51] <zeeshan> so it drops on em first
[02:34:53] <zeeshan> or some wood
[02:34:58] <ssi> I don't like electricity that can jump out and bite me
[02:35:00] <ssi> heheh
[02:35:15] <andypugh> I was looking to run a 440V 3-phase motor from a domestic supply and VFD.
[02:35:47] <andypugh> Yeah, something my dad taught me to do was to throw the spare wheel under the car with you.
[02:36:11] <andypugh> (In the absence of anything better)
[02:36:45] <zeeshan> andypugh: you have 3 phase?

[02:39:10] <ssi> hm neat
[02:39:29] <PetefromTn_> Mine has been gutted of the electronics
[02:39:32] <andypugh> But the most scary thing I built was a mechanical testing machine. 100kg flywheel at 3000rpm, pneumatic clutch, and a cam. the platten did 0 - 50mph in 7mm.
[02:39:42] <PetefromTn_> which is why I am getting it cheap.
[02:39:45] <ssi> yeah that's a bit scary :P
[02:39:47] <zeeshan> haha andypugh
[02:39:50] <zeeshan> thats a lotta energy
[02:40:09] <XXCoder> oh yeah. I used a cnc machine to make tap block. man it took forever. over 100 times facemill passes
[02:40:09] <zeeshan> im liking that lathes shield
[02:40:13] <zeeshan> i need to do that for my lathe
[02:40:15] <andypugh> And it was a click of a mouse to engage the clutch. That was a scary mouse-click.
[02:40:37] <zeeshan> andypugh: did anything blow up
[02:40:58] <andypugh> About half the time the cam-roller or platten escaped. Yes.
[02:41:04] <zeeshan> :D

[02:41:32] <zeeshan> im afraid of flywheel explosions
[02:41:35] <zeeshan> this thing had a 28lb flywheel
[02:41:36] <PetefromTn_> Should be a nice project and once it is CNC again it will make a sweet lathe.
[02:41:47] <zeeshan> *has
[02:41:54] <XXCoder> 3 bucks per pound
[02:41:59] <XXCoder> that good?
[02:42:09] <ssi> zeeshan: I've seen flywheel explosions... they're not pretty
[02:42:10] <PetefromTn_> it has a D1-6 spindle face and you can put a collet closer on it pretty easy.
[02:42:10] <cathode> not sure. i think so compared to new pricing
[02:42:14] <zeeshan> me too
[02:42:23] <zeeshan> it destroys feet, hoods, interior dash, engine block
[02:42:25] <zeeshan> transmission
[02:42:30] <zeeshan> pretty much everything

[02:42:39] <cathode> how does a flywheel explode?
[02:42:50] <XXCoder> metal fatique, vibration
[02:42:51] <ssi> cathode: it fails at high speed
[02:42:52] <XXCoder> so on
[02:42:55] <zeeshan> usually fatigue
[02:42:57] <cathode> hmmm
[02:43:03] <zeeshan> thermal fatigue is one major reason
[02:43:05] <zeeshan> or misalignment
[02:43:10] <zeeshan> or bolts baking off
[02:43:13] <XXCoder> high speed flywheel is scary
[02:43:18] <XXCoder> expecially heavy one
[02:43:34] <zeeshan> i never run aluminum flywheels for this reason
[02:43:34] <ssi> I saw one where someone blew a downshift from sixth to second
[02:43:38] <zeeshan> because they dont have an endurance limit
[02:43:39] <ssi> overrevved the piss out of it, and the flywheel blew up
[02:43:55] <PetefromTn_> http://www.moderntool.com/products/modern-446-mp-micropanther-teach-type-cnc-lathe/ That looks like a sweet little lathe.
[02:44:15] <XXCoder> no price. you cant afford it
[02:44:17] <ssi> MICROPANTHER
[02:44:27] <ssi> 17x35 isn't exactly little :)
[02:44:32] <PetefromTn_> I don't need to afford it I have one very similar LOL
[02:44:38] jdh is now known as jdhInFlorida
[02:44:44] <ssi> I see what you mean about the handwheels
[02:44:45] <ssi> that's weird
[02:45:06] <PetefromTn_> yeah mines about 15x40 apparently
[02:45:11] <ssi> that's a good size
[02:45:24] <cathode> so, flywheel explosion in the context of a car, right?
[02:45:25] <PetefromTn_> yeah I think it will be perfect for what I need to do.
[02:45:49] <zeeshan> cathode: yes
[02:45:50] <PetefromTn_> I can do close up collet work and if I need to throw a big shaft in there from my Bronco or something it is a done deal
[02:46:13] <PetefromTn_> It apparently came with either a 1.53 or 2" spindle bore.
[02:46:14] <cathode> my bandsaw has a 3-belt sheave/pulley that is solid cast iron and weighs about 25lbs, but i'm only spinning it at 700rpm. i don't think i need to worry....right?
[02:46:23] <PetefromTn_> Not sure what mine is but HOPING it is the larger one LOL
[02:46:26] <ssi> http://atlanta.craigslist.org/nat/tls/4712896213.html
[02:46:28] <ssi> that's a beauty
[02:46:33] <zeeshan> cathode: you should have a shield around it
[02:46:38] <zeeshan> incase the sheave loosens up
[02:46:40] <zeeshan> and flies out
[02:46:41] <andypugh> PetefromTn_: Looks nice, and seems set up for manual work too. (not that I see the point)
[02:46:44] <zeeshan> or the belt snaps
[02:46:52] <cathode> hmmm
[02:46:58] <PetefromTn_> yeah that is kinda what I like about this type
[02:47:03] <PetefromTn_> It can do kinda both
[02:47:12] <cathode> well, i was going to build a 1/2" plywood housing around that area
[02:47:31] <PetefromTn_> Should be a pretty simple retrofit to LinuxCNC I hope.
[02:47:31] <zeeshan> cathode: i doubt it'll ever explode
[02:47:34] <zeeshan> it might fall off.
[02:47:46] <zeeshan> flywheel explosions are literally a shatter of chunks of steel
[02:47:47] <zeeshan> or aluminum
[02:47:53] <zeeshan> that are like bullets
[02:47:53] <PetefromTn_> ssi I used to have a lathe about that big for awhile here
[02:48:02] <PetefromTn_> it was like 16x80 or something
[02:48:07] <PetefromTn_> Weighed like 5k
[02:48:16] <andypugh> PetefromTn_: FWIW I set up my lathe to be manual too, but I have never felt the urge. Givem that I have macros for normal lathe ops, the CNC ends up like a better version of power feed (no G-code needed most days)
[02:48:19] <PetefromTn_> maybe more I don't remember
[02:48:31] <cathode> yea i googled and found a picture of a van that had a hole punched through the side (through-and-through) and the caption said that a 14lb chunk of flywheel had flown half a mile after busting through the van
[02:48:32] <zeeshan> andypugh: i agree!
[02:48:37] <PetefromTn_> Oh I don't mean literally both manual and CNC
[02:48:40] <zeeshan> i run the lathe in feed all the time
[02:48:51] <PetefromTn_> I mean that the layout of the lathe is very similar to my 12x36 manual lathe
[02:48:53] <zeeshan> cathode: lol
[02:49:01] <ssi> http://atlanta.craigslist.org/nat/tls/4709490124.html
[02:49:05] <ssi> that's got some promise too, for the money
[02:49:21] <PetefromTn_> I fully intend it to be full CNC control and jog etc like I run my Cincinatti for manual milling etc.
[02:49:51] <PetefromTn_> I will certainly miss my asian 12x36
[02:49:58] <PetefromTn_> it was a great little machine.
[02:50:06] <XXCoder> cathode: it is cheaper
[02:50:11] <PetefromTn_> ran good for a very long time for me
[02:50:24] <XXCoder> 8.43 for 2 feet 2020 compared to amazon $15.73

[02:52:30] <ssi> andypugh: 95k seriously?
[02:52:31] <ssi> that's insane
[02:52:45] <ssi> they're nice lathes, but cmon
[02:52:46] <XXCoder> cathode: I had link to howto to make shitty lathe so you can make bigger and better lathe out of that
[02:52:47] <PetefromTn_> yeah but a MOnarch 10 is a gorgeous machine.
[02:52:52] <andypugh> My Rivett 608 was $2000. In 1936!
[02:52:55] <XXCoder> been years now. robably gone now
[02:53:19] <andypugh> What did $2000 buy you in 1936?
[02:53:27] <cathode> http://www.practicalmachinist.com/vb/monarch-lathes/why-does-monarch-10ee-lathe-exist-100737/
[02:53:43] <PetefromTn_> http://www.cnccookbook.com/img/Workshop/GreatShops/BerniesShop/DCP01021.jpg
[02:54:22] <cathode> XXCoder - i've seen a guide for building a lathe that was targeted towards like, someone setting up a machine shop in a third world country. they used a combination of inexpensive raw stock and poured concrete for the frame
[02:54:33] <XXCoder> yeah I have that one
[02:54:44] <XXCoder> it was orginially invented for world war 1
[02:54:47] <cathode> the idea was that in a place with no access to ordinary tools, a lathe would let you get most of the parts fabricated that would be necessary to make other machines
[02:54:49] <PetefromTn_> Looks like a classic car only prettier LOL
[02:54:52] <XXCoder> usa DESPERATELY needed lathes
[02:55:08] <PetefromTn_> I Desperately need a CNC lathe LOL
[02:55:10] <cathode> ah yea
[02:55:21] <ssi> I've always wanted to set up a small iron foundry so I can design, cast, and finish machine some machine parts
[02:55:24] <ssi> make my own lathe etc
[02:56:06] <XXCoder> yeah. $200 lathes when period was 10 times more expensive and metal was hard to come
[02:56:19] <andypugh> I think that the Monarch took over from the Rivett as the lathe you bought to prove that you had bought the best possible lathe.
[02:56:47] <cathode> casting is an interesting project
[02:56:55] <andypugh> When the Rivett was $2000 a Myford ML4 was £40
[02:57:01] <cathode> if you can cast things out of metal, you can do almost anything
[02:57:14] <XXCoder> is it hard to cast cast iron?
[02:57:16] <ssi> then you see shit like this and you want to cry
[02:57:17] <ssi> http://www.govdeals.com/index.cfm?fa=Main.Item&itemid=12&acctid=3559

[02:58:28] <PetefromTn_> I am sure it will take some time and work but I think I will be very pleased with this Standard Modern I am picking up tomorrow.
[02:59:17] <PetefromTn_> But I better get my ass in bed so I can wake up and get rolling in the morning. Plus I gotta get some tools and heavy straps etc ready before I hit the sack. Gn8 folks.

[03:01:21] <cathode> so that when a deal like that comes along i don't have to feel guilty
[03:01:31] <ssi> cathode: I do that... whenever I sell something for cash i stick it in my safe and don't touch it for tool purchases
[03:01:32] <SpeedEvil> zeeshan: The bearings are just fine
[03:01:32] <zeeshan> what kind of lathe?
[03:01:39] <andypugh> I bought my CNC lathe brand-new for £700, spent £700 converting to CNC, and now it is worth £200. It’s rubbish. I regret it.
[03:01:39] <SpeedEvil> zeeshan: the spindle is rather bent
[03:01:43] <zeeshan> doh
[03:01:52] <PetefromTn_> why?
[03:01:53] <zeeshan> andypugh: lol
[03:02:01] <cathode> currently, i only have a woodshop. not a machine shop
[03:02:11] <ssi> cathode: that's ok, we all have mistakes in our past
[03:02:15] <SpeedEvil> zeeshan: it was used to turn large bowls, and an incident happened. (metal lathe converted towood)
[03:02:16] <PetefromTn_> what kind of CNC lathe is it?
[03:02:24] <zeeshan> ah
[03:02:36] <cathode> the only vaguely metalworking-ish tool i have is my 15" drill press that i bought earlier this year on craigslist
[03:02:56] <PetefromTn_> andypugh What kind of CNC lathe is it?
[03:03:18] <ssi> andypugh: that chinese 3-in-1 monstrosity of yours?
[03:03:59] <XXCoder> cat wood lathe can turn metal apparently just need be careful
[03:04:01] <andypugh> Pete, it’s a nasty chinese 6x20 stretched to 9 x 40 but without any extra bed width, or any care in assembly, or any design. or parts quality. Then a milling column was added to really highlight the defficiencies in the ways.
[03:04:20] <andypugh> ssi: That;s the one
[03:04:21] <PetefromTn_> OH that kinda sucks
[03:04:24] <ssi> andypugh: :)
[03:04:33] <ssi> andypugh: at least you have perspective!
[03:04:45] <PetefromTn_> the Standard Modern was apparently made in Canada believe it or not
[03:04:57] <ssi> PetefromTn_: uh oh, nothing good comes from canada!
[03:05:04] <PetefromTn_> no shit right LOL
[03:05:15] <andypugh> Yeah, I now know how to do the job right. I am very happy with the Harrison mill conversion.
[03:05:17] <PetefromTn_> at least it is NORTH AMERICA
[03:05:32] <ssi> yes, it's north of america

[03:05:50] <ssi> andypugh: I've built a handful of machines that never even got to be machines
[03:05:51] <PetefromTn_> I think it will just be nice to finally have a real CNC lathe that I can make some parts on
[03:06:29] <PetefromTn_> Oh are they UK?
[03:06:52] <cathode> hey guys
[03:07:02] <ssi> andypugh: like this thing: https://www.youtube.com/watch?v=GEAsDafIYUI
[03:07:16] <ssi> I built that from scratch after I got my bridgeport, from looking at other peoples' router designs on cnczone
[03:07:18] <XXCoder> Canada is north america too ya know
[03:07:35] <ssi> it had potential, but the way the gantry was attached to the base and moved on its rails was crap, and it had like 1/4" of nod to it

[03:08:13] <cathode> i have a question about fasteners. i need to secure some pillow block bearings to some heavy steel angle, what would be the best approach to preventing the screws from backing out or loosening? should i go for serrated-flange hex bolts or lock washers? or thread-locking compound?
[03:08:17] <ssi> PetefromTn_: the Y axis needs to be completely redesigned
[03:08:25] <PetefromTn_> Got that covered
[03:08:29] <PetefromTn_> ;)
[03:08:30] <andypugh> PetefromTn_: No, Standard modern are Canadian, but that web page has a company history.
[03:08:30] <zeeshan> cathode: high vibration environment?
[03:08:41] <PetefromTn_> yeah I was just reading that
[03:08:43] <PetefromTn_> interesting
[03:08:45] <zeeshan> there shouldnt be too much vibration if the assembly is balanced
[03:09:04] <PetefromTn_> sounds like they made lathes for the US military.
[03:09:11] <PetefromTn_> Hopefully that means they are good quality
[03:09:20] <PetefromTn_> From what little I have read they were well regarded
[03:09:43] <cathode> zeeshan - i would consider it a high vibration environment
[03:09:59] <zeeshan> theres so many approaches to it
[03:10:04] <zeeshan> depends on how hardcore you wanan go lol
[03:10:09] <zeeshan> simple loctite red works
[03:10:27] <andypugh> cathode: Thread locking compound, I would say. Or maybe Nyloc nuts.
[03:10:28] <cathode> i want to pick 3 out of: cheap, easy, effective
[03:10:30] <zeeshan> you can use external tooth lock washers
[03:10:49] <andypugh> Anyway, bed time.
[03:10:49] <zeeshan> then you can use distorted nuts.
[03:11:01] <zeeshan> and if you want superior, you can use safety wire
[03:11:05] -!- andypugh has quit [Quit: andypugh]
[03:11:06] <cathode> andypugh - ok. two of my pillow blocks have tapped holes in the base instead of through-bolt feet
[03:11:20] <ssi> <3 safety wire
[03:11:33] <zeeshan> i always throw safety wire on turbine housings now
[03:11:38] <cathode> mcmaster has self-locking bolts that have threads scooped out and replaced with nylon. are those any good?
[03:11:40] <zeeshan> cause its the only thing that will handle the high heat
[03:12:08] <ssi> zeeshan: metal locknuts if it's a throughbolt
[03:12:10] <cathode> ah you need drilled-head bolts to use safety wire...
[03:12:20] <zeeshan> cathode: you can drill them yourself
[03:12:28] <zeeshan> but im pretty sure loctite red work work in your application

[03:15:36] <ssi> the mil spec ones are over a dollar apiece at mcmaster :P
[03:16:07] <cathode> oh
[03:16:20] <ssi> also I have a dealer account at spruce and hardware is mostly 20% off for dealer accounts
[03:16:41] <ssi> the weird thing though is spruce doesn't carry aircraft engine hardware at all
[03:16:57] <ssi> everything on an airframe is AN, which is all UNF
[03:17:03] <ssi> but everything on lycoming engines is UNC
[03:17:10] <ssi> and spruce carries zero UNC hardware
[03:18:23] <cathode> ok this might be a stupid question but when you use a flat washer, with a lock washer above it... does that defeat the purpose of the lock washer?

[03:18:58] <cathode> i want to drill slightly oversize holes so that i have some wiggle room to adjust my pillow blocks
[03:19:23] <ssi> cathode: split washers work with flat washers, but I don't think tooth washers do
[03:19:30] <cathode> ok
[03:19:42] <cathode> this is why i was leaning towards serrated flange nuts
[03:20:33] <cathode> i've used grade 5 serrated flange bolts and nuts when assembling pallet racking, they chew up the surface real bad but otherwise they seem to hold really well
[03:20:58] <cathode> sometimes it requires a beefy impact driver to undo them, after they've been tightened by hand with a small wrench
[03:21:04] <ssi> "Toss the helical-split, internal-toothed, and external-toothed lock washers. I've tested these on railroad equipment. Bolted joints without are better than with! The lockwashers make the joints softer and drive the natural frequencies down. Instead use Bellville, wavy-spring, or cupped spring washers!
[03:21:09] <ssi> Best of all, use prevailing-torque locking methods ala nylon patched screws or self-locking nuts with nylon locking element."
[03:21:49] <cathode> ok
[03:22:10] <cathode> i might get some of the nylon patched bolts for fastening the pillow blocks with tapped holes

[04:13:05] <cathode> because i just paid 5x for something and often times i have to settle for less-than-ideal
[04:13:12] <zeeshan> haha
[04:13:15] <zeeshan> yea home depot is pretty expensive
[04:13:20] <zeeshan> but in a bind
[04:13:22] <cathode> for example, their fastener "selection" is pretty worthless
[04:13:22] <zeeshan> theyre awesome
[04:13:26] <zeeshan> and they dont care about quantity.
[04:13:36] <zeeshan> i have a fastner suplier locally
[04:13:41] <zeeshan> its cheaper to buy a 100 of something
[04:13:45] <zeeshan> vs buying 4 of them at home depot
[04:13:46] <zeeshan> lol
[04:13:57] <zeeshan> like socket heads cap screws 1/4" x 1"
[04:14:02] <zeeshan> will be like 7$ per box
[04:14:05] <zeeshan> 100.
[04:14:09] <cathode> yep
[04:14:11] <zeeshan> you'll pay like that much for 4 at home depot
[04:14:19] <cathode> it's pathetic

[04:14:46] <cathode> i'm not a big tree hugger or anything but seriously... ONE BOLT per plastic bag? wtf
[04:14:51] <zeeshan> lol
[04:14:58] <XXCoder> yeah
[04:15:11] <cathode> there's an Ace Hardware franchise branch/store locally that has almost as good of a selection as mcmaster
[04:15:26] <zeeshan> the biggest rip off on the planet
[04:15:29] <zeeshan> is grainger
[04:15:29] <cathode> but they're a bit more expensive
[04:15:32] <cathode> yep
[04:15:35] <zeeshan> a box of 100 bolts of the same size
[04:15:37] <zeeshan> is like 40$

[04:18:47] <cathode> i didn't count, some of the boxes are missing some fasteners, but all told it's about 1500-1600 pcs. and they were oiled from the factory so there's no rust, even though it's probably 50 years old
[04:18:52] <zeeshan> the big boxes look like 1000 qt

[06:02:11] <zeeshan> when i took apart the pump assembly from the reservoir
[06:02:15] <zeeshan> it spins a bit easaier.
[06:02:28] <zeeshan> maybe the reservoir vent is clogged

[06:02:44] <zeeshan> im going to attempt to try tomorrow :)
[06:02:47] <zeeshan> enough work for the night
[06:05:37] <MrSunshine> ough ... sounds like fun =)

[06:06:44] <cathode> true
[06:06:49] <MrSunshine> i recently fixed the motor stuff on my compressor ... it would blow one phase .. turned otu it was the motor protection stuff that was burnt .. 7 ohms over just ordenary closing contacts .. with one of them just closing intermittent =)

[06:07:46] <zeeshan> honestly it doesnt sound like a burned motor

[06:41:22] <zeeshan> :P
[06:41:28] <zeeshan> the harder grades that is
[06:41:39] <cathode> gotcha. so quite a lot of processing per bolt

[06:44:32] <zeeshan> 47 seems like a lot for 1 bolt
[06:45:02] <zeeshan> should be around 3-5$

[06:47:13] <zeeshan> some sort of press?
[06:47:21] <cathode> i'm building a unit that will slide vertically and hold the upper wheel of my bandsaw
[06:47:33] <zeeshan> looks beefy :)
[06:47:34] <zeeshan> i like it
[06:47:34] <cathode> the pneumatic pistons will apply tension to the bandsaw blade
[06:47:44] <cathode> it's infinitely better than a spring and screw like most have
[06:47:58] <cathode> springs can't apply much force (relatively), and they wear out and fail over time
[06:48:09] <zeeshan> cars usually make use of hydraulic tensioners
[06:48:21] <zeeshan> ive never seen pneumatic,
[06:48:24] <zeeshan> it looks interesting :)
[06:48:26] <cathode> i have a pressure regulator that will control the amount of tension on the blade.

[06:49:00] <zeeshan> so this is kind of like

[06:49:03] <zeeshan> for cars :D
[06:49:04] <cathode> yeah
[06:49:31] <cathode> hypothetical situation: a chip of wood lands on the bandsaw wheel and gets wedged under the blade, pushing it out
[06:49:43] <cathode> you want there to be a little bit of "give" in the tension
[06:49:47] <cathode> so that it doesn't snap the blade
[06:50:22] <zeeshan> yea
[06:50:26] <zeeshan> keep it at the ideal tension
[06:50:27] <zeeshan> all the time
[06:50:53] <cathode> yep... and because i know the surface area of the cylinders, i can print out a little chart
[06:51:07] <cathode> that will tell me how many pounds of tension at a given PSI
[06:52:02] <cathode> this is one of the wheels, i was testing the mounting to the shaft. https://www.dropbox.com/s/sf1agkgfvqwuu6l/2014-10-23%2021.17.12.jpg?dl=0

[06:53:07] <zeeshan> you have some crazy wood working skills
[06:53:08] <zeeshan> :)
[06:53:17] <cathode> lol
[06:53:20] <cathode> er, thanks
[06:53:36] <zeeshan> howd you make that wheel's outer rim?
[06:53:37] <zeeshan> so round
[06:53:47] <zeeshan> thats a huge wheel
[06:54:17] <cathode> spun it on a piece of plywood that was clamped to the table saw
[06:54:30] <cathode> so the wheel spun freely with a makeshift axle
[06:55:05] <cathode> once it's actually installed, it will get a second treatment with more accuracy
[06:55:43] <cathode> the whole project is using repurposed or discounted materials. the only thing i've bought new has been fasteners, and some electrical stuff
[06:57:01] <cathode> the frame is made of layers of 5/8" wood boards laminated together under substantial pressure. https://dl.dropboxusercontent.com/u/88948814/Shop/Bandsaw/2014-05-19%2020.57.41.jpg

[06:57:52] <zeeshan> thats a lotta clamp
[06:57:56] <zeeshan> thats like 300$ in clamps
[06:57:56] <zeeshan> haha
[06:57:59] <zeeshan> or even more
[06:58:05] <cathode> nahhhh, half of those are from harbor freight
[06:58:17] <cathode> i bought about 25 clamps just to finish this project. haha
[06:58:29] <cathode> you can never have too many clamps, you know.
[06:58:40] <zeeshan> haha i have like 30 c-clamps
[06:58:41] <zeeshan> that i use for welding
[06:58:52] <zeeshan> still not enough

[07:02:25] <zeeshan> nicee
[07:02:48] <cathode> do you use acid wash or electrolysis to remove rust?
[07:03:00] <zeeshan> either works
[07:03:01] <cathode> or just an angle grinder with a wire brush wheel?
[07:03:07] <zeeshan> people use muratic acid
[07:03:09] <zeeshan> i personally sand blast it
[07:03:12] <cathode> ahh
[07:03:21] <cathode> i didn't want to pit or damage the sheave
[07:03:29] <zeeshan> you can use a light media
[07:03:31] <cathode> in case it created a rough spot that caused wear on the v-belt

[07:07:33] <cathode> at the moment i'm trying to decide if i want to try and use this bandsaw for both wood and metal. originally i was planning on using it for only cutting wood
[07:08:02] <zeeshan> youd need to do something about protecting the wood pulleys
[07:08:08] <zeeshan> so the cutting oil doesnt own them
[07:08:15] <cathode> yeah
[07:08:32] <cathode> hmm. i guess i'll stick to my jigsaw for metal for now. i don't really cut metal much
[07:08:46] <cathode> i could always get a separate smaller bandsaw for cheap on craigslist

[07:40:48] <D3add3d> Hello, can someone tell me if it is possible to install LinuxCNC on Ubuntu 14.04?
[07:41:46] <D3add3d> on wiki there are only instructions for Ubuntu 8 and 10
[07:43:43] <archivist> because the realtime was lagging, people are testing and working on the later also testing on debian
[07:51:58] <D3add3d> ah... ok, I'll test and see if it will run smoothly on my i7 (4 c., 8 th. @ 4.3GHz) with 32GB HyperX Red RAM :-D
[07:53:05] <archivist> getting the realtime going will be the interesting part
[07:53:38] <archivist> look in the mailing list archives to see what people have been doing
[07:59:49] <D3add3d> oh... I can also put it on Raspberry Pi? I have a dozen lying around(they were used for proof of concept cloud computing test)
[08:00:25] <archivist> bit hard to fit on a pi
[08:01:18] <archivist> see here http://www.raspberrypi.org/forums/viewtopic.php?t=33809
[08:02:44] <archivist> just easier to use the pre done live CD image
[08:03:42] <D3add3d> yeah... I guess I will have to go buy some CDs
[08:04:45] <archivist> some put it on a usb stick and boot from that
[08:06:22] <D3add3d> Well, my usb sticks are all currenty used and CDs are really cheap

[15:01:51] <tjtr33> my servo project needs 31outputs and 25 inputs. I have a 5i20, a 7i33 and 2 7i37 on hand.
[15:01:57] <tjtr33> I bump into the old industry std of 16in and 8 out as a limitation.
[15:01:57] <tjtr33> Any reason stopping a 5i2x from being all outputs? ( say I use Mariss's opto coupler idea at 320uA each )
[15:02:21] <tjtr33> http://www.anderswallin.net/2006/08/optoisolator-cards-for-mesa-5i20-servocard/
[15:05:55] <pcw_home> any pin can be a GPIO input or output though theres some dependence on the configuration
[15:05:57] <pcw_home> (because the driver only knows how to enable stepgens or PWMgens on 0 to N basis)
[15:08:57] <tjtr33> i think i understand, so, on a 5i20, past the 1st 'channel' 7i33, the 2nd & 3rd 50pin 'channels' could be all outputs?
[15:09:15] <pcw_home> Yes
[15:09:17] <pcw_home> If you use OPTOs I would suggest you use common Anode connected to cable pin 49 (5V)
[15:09:18] <pcw_home> and then use open drain mode so the outputs swing to 5V to make sure the OPTOS are completely off
[15:09:35] <pcw_home> (and all off at startup)
[15:11:07] <tjtr33> i dont find daughterboards that allow that :( am I on my own, or any chance I'd ever see a daughterboards with maybe pluggable sets of 8ins or 8outs (as you wish :)

[15:12:45] <pcw_home> you could use a 7I71/72 for outputs

[15:14:35] -!- skunkworks has quit [Ping timeout: 265 seconds]
[15:14:51] <tjtr33> they drive opto-22 relays, so 3-32V, i dunno the current drive required.
[15:14:53] <tjtr33> Thanks i been looking at the mesa page and didnt see that as an option.
[15:15:20] <tjtr33> i'm looking to find the 48 input card i must have overlooked now
[15:15:53] <pcw_home> if they are 24 I/O racks you can drive them directly from 5I20 outputs
[15:17:06] <tjtr33> scattered , not racks, so the daughtercards with terminal strips look nice
[15:17:27] <tjtr33> and the 7i70 is the 48 input
[15:18:42] <pcw_home> a 7I71 or 72 gives you 48 12/24V outputs, the 7I70 gives you 48 inputs (also 12/24V)

[21:11:09] <tjtr33> i want to spreadsheet the pinouts for 5i15/7i77, but dont have the hdwr yet.
[21:11:22] <tjtr33> Does hm2_5i25.0.7i77.0.0.input-10-not wire to 1st 5i25, 1st 7i77, TB8 pin11 ( read as neg logic)?
[21:11:29] <tjtr33> and hm2_5i25.0.7i77.0.1.analogena is wired to TB5 1,2 or similar pair?
[21:11:30] <tjtr33> ( wire any 1 of these pairs as active high/low as needed and enables0-4 act in unison )

[21:18:54] <tjtr33> thx JT-Shop , its the ..0.0.. and ..0.1.. that threw me, i'm guessing .0.0 means TB7&8 and .0.1 means TB5
[21:21:10] <JT-Shop> I'd have to look
[21:22:21] <tjtr33> dont stop what you're doin, I'll try to ask Peter when he gets back, thx
[21:22:48] <JT-Shop> 0.0 is card 0 ie the 7i77
[21:23:18] <JT-Shop> 0.1 would be a second card plugged into the 5i25
[21:23:40] <tjtr33> in your config for BP you mention 0.0 and 0.1 do you have 2 5i25's in that system?
[21:24:02] <tjtr33> in bp.hal
[21:24:11] <JT-Shop> no, the 0.1 is for the analogout pins
[21:24:17] <JT-Shop> just looking now
[21:25:17] <tjtr33> ok analog out is on TB5 ( 0,1 ) and digital is on TB7&8 (so i guess 0.0)
[21:25:30] <JT-Shop> yep
[21:25:37] <tjtr33> hey thanks!
[21:25:49] <JT-Shop> I have a pin out of the 7i77 (hal pins) if you want it
[21:26:08] <tjtr33> i picked it up from gnipsel ( very handy site :)
[21:26:10] <JT-Shop> also in the mesa manual is the terminal block pin out
[21:26:14] <JT-Shop> ok cool
[21:26:44] <tjtr33> do you have a hal dump of the named pins?

I assume that using one of these for the basis of a multipurpose machine - including a 3d printer would be a bad idea due to the very large number of (admittedly zero load) cycles?

[21:52:46] <tjtr33> i got 2 fehlmans ( top of the line swiss made) you could have for postage ( figger 25 kg each and 150x300mm motion, brass nuts, 2mm pitch box thread )

[21:59:18] <tjtr33> notice its built with deep gutters, they made them for 1970's AGie edm machines, a plexi box was strapped to outer edge
[22:09:58] <tjtr33> thought i recognized something, fullerton CA is Gaiser tool, they do bonding tools and had loads of AGie AB's with those tables. bonding tools is tiny stuff, welds they wires inside chip from the legs to the die
