[00:07:32] <zeeshan> i was sitting down and getting a silly idea
[00:07:49] <zeeshan> is there a reason why you cant mount a regular 12x36 lathe horizontally?
[00:07:54] <zeeshan> so that instead of the chips collecting on the ways
[00:07:57] <zeeshan> they go straight down
[00:08:17] * zeeshan ends random idea
[00:09:21] <CaptHindsight> zeeshan: like a wall mount lathe?
[00:09:34] <zeeshan> haha yea!
[00:09:38] <zeeshan> literally

[00:24:45] <andypugh> Cromaglious_: If the white metal bearings are good, what makes you think that you need something else?
[00:26:02] <Cromaglious_> well I need a better oiler OR roller bearings.
[00:26:47] <andypugh> But, if the white metal bearings are working, I would say that the evidence is that you don’t need to change to a different type pf bearing.
[00:27:08] <andypugh> (at the very least you might as well wait until the plain bearings die)
[00:27:44] <Cromaglious_> it'll run all day if I add oil every 10 minutes, I'd like to get a big oiler so I can set a drip rate which the babbit ants
[00:27:51] <Cromaglious_> s/ants/wants/
[00:28:20] <andypugh> Plain bearings are alleged to give a better finish.
[00:28:52] <Cromaglious_> sure do, IF they are bathed in oil.

[01:53:44] <zeeshan> what happens in the first minute or so is
[01:54:25] <zeeshan> diamond's carbon atoms have a high affinity for other carbon atoms
[01:54:39] <zeeshan> so under the heat of cutting, the carbon starts to get extracted from the steel
[01:54:50] <zeeshan> and into the diamond cutting tool destroying the cutting edge

[02:49:55] <Tecan> zeeshan the graphite helps lube it naturally ?
[02:50:00] <zeeshan> tecan yes
[02:50:03] <Tecan> neat
[02:50:06] <Cromaglious_> can you lay a cheap cotton across the bottom of your pan to catch all the bronze? loose enough weave for the coolant to get thru, something like a country classic quilting cotton. not a sheet

[03:24:24] <PetefromTn_> good now you can explain it to the rest of us mere mortals
[03:24:24] <zeeshan> radial rake angle (milling) == side rake (turning) == helix (drilling) == rake (broaching)

[03:31:08] <PetefromTn_> on the cheap side I have some fastenal taps and they are spiral point and work quite well, cut nice and easy. on the expensive side I have OSG and Morse and they are the best usually.
[03:31:32] <roycroft> the ones that were breaking are irwin, and the new ones that seem to do better are century
[03:31:38] * zeeshan buys my taps in lots
[03:31:45] <zeeshan> roycroft: irwin fresh china!
[03:31:48] <roycroft> i broke a number of 4-40 taps, a few 6-32, and even a 1/4-20
[03:31:54] <roycroft> yes, zeeshan
[03:32:05] <PetefromTn_> a good tap is worth every penny
[03:32:05] <zeeshan> 4-40 i understand
[03:32:05] <roycroft> i should buy them in packs of 5 or 10 from a proper tooling supplier
[03:32:11] <zeeshan> a little angle and snap
[03:32:18] <zeeshan> but 6-32 and 1/4 especially those are hard to break
[03:32:21] <roycroft> yes, but i am pretty careful
[03:32:35] <roycroft> and i always tap right on the milling machine, so i can chuck the tap to start it
[03:32:58] <roycroft> i chuck it up, turn it about 3 revolutions, raise the chuck and attach the tap handle
[03:33:18] <roycroft> and i use a really small tap handle on 4-40 taps
[03:33:28] <zeeshan> one brand is widia
[03:33:31] <zeeshan> is that any good
[03:33:34] <zeeshan> thats what some of mine are
[03:33:50] <roycroft> i also bore out the holes the proper size
[03:33:55] <zeeshan> i believe you :)
[03:34:01] <roycroft> i don't use the closest fractional bit - i use number and letter bits

[03:34:12] <roycroft> or fractional bits, when that's the correct size
[03:34:14] <zeeshan> bid on those! :D
[03:34:18] <zeeshan> thats how i buy my shit

[03:34:33] <zeeshan> better
[03:34:56] <roycroft> yeah, i should do that
[03:35:05] <roycroft> i never bought a set of taps and dies
[03:35:35] <roycroft> so i don't have a case that holds one of each - i have one of those wall-mounted drawer storage things and stick one type in each drawer
[03:35:44] -!- The_Ball has quit [Ping timeout: 272 seconds]
[03:35:58] <roycroft> i put dies, all 3 types of hand taps, and the proper drill bits in each drawer
[03:35:59] <zeeshan> i got a kennedy box for $70
[03:36:02] <roycroft> so i never have to think about it
[03:36:02] <zeeshan> i store em in that
[03:36:37] <roycroft> anyway, i had been buying irwin for years, because the store right by my house carried them
[03:36:43] <roycroft> and i never had problems until recently

[03:37:04] <roycroft> i thought it was just me getting old and not being able to run the tap down carefully any more
[03:37:11] -!- JohnyK [JohnyK!~wity@witypc.ynet.sk] has joined #linuxcnc
[03:37:24] <roycroft> but now i blame the tooling!
[03:37:52] <zeeshan> i think chinese tools suck at cutting
[03:37:59] <zeeshan> because they cant get away with shitty materials engineering
[03:38:04] <zeeshan> =D
[03:38:09] <zeeshan> or heat treatment
[03:38:47] <roycroft> yes, they generally do
[03:38:52] <roycroft> i'm sure they make good tooling
[03:38:55] <roycroft> which they use themselves
[03:39:07] <roycroft> but once it gets on the boat it's not coming back, so they don't care
[03:39:34] <roycroft> those taps you pointed me to have a reserve
[03:39:46] <roycroft> i just bid $7.99 to see and it did not meet the reserve
[03:39:47] <zeeshan> look @ second link
[03:39:58] <zeeshan> it has no reserve
[03:40:10] <roycroft> i didn't notice the second one
[03:40:33] <zeeshan> imperial taps i can find cheap on ebay
[03:40:37] <zeeshan> but fuck man, metric taps
[03:40:38] <zeeshan> impossible.

[03:40:50] <zeeshan> look at this
[03:40:52] <roycroft> i'm not sure i need a dozen 1/4-20 taps
[03:40:55] <zeeshan> this isn't bad
[03:41:07] <roycroft> the one i broke recently is the only one i ever remember breaking
[03:41:13] <roycroft> and i don't wear them out that quickly
[03:41:40] <roycroft> for 6-32 and smaller i would not mind having a dozen
[03:41:57] <roycroft> but 8-32 and larger 5 or so would be plenty for a while, unless i got a great deal
[03:42:16] <roycroft> and i do like having starter, plug, and bottom taps
[03:42:56] <roycroft> with really small taps i use bottom taps even when i'm not tapping a blind hole
[03:43:03] <zeeshan> why
[03:43:20] <roycroft> just because they're so easy to break - i go down to the depth i need with the starter tap, then chase it down with the bottom tap
[03:43:26] <roycroft> and i try not to tap deeper than i need
[03:43:31] <roycroft> to reduce the change of breaking the tap
[03:43:35] <zeeshan> ah
[03:43:45] <zeeshan> i guess the lead in makes it easier to tap
[03:43:52] <roycroft> yes
[03:44:13] <zeeshan> wow

[03:44:20] <zeeshan> this has to be the most expensive countersink i nthe world
[03:44:31] <roycroft> i tapped a dozen 4-40 holes without incident today
[03:44:32] <zeeshan> 3"
[03:44:33] <zeeshan> lol
[03:44:40] <roycroft> a couple months ago i'd break one every 3rd or 4th houle
[03:44:41] <roycroft> hole
[03:44:55] <zeeshan> ive only broken one tap =/
[03:45:06] <zeeshan> trying to tap a hole that was laser cut in stainless
[03:45:09] <zeeshan> snap
[03:45:13] <roycroft> i don't mind breaking the tap so much as having to remake the part after

[03:45:26] <roycroft> that would do it
[03:45:33] <zeeshan> hi bob
[03:45:34] <zeeshan> o
[03:45:35] <roycroft> the laser really hardened the ss, i'm sure
[03:45:44] <zeeshan> yea back around this time
[03:45:46] <zeeshan> i was clueless
[03:45:55] <roycroft> all you have to do is look at ss and it starts case hardening
[03:46:01] <zeeshan> haha
[03:46:18] <bobo> Hi Mr. Pete@Mr Zeeshan @ all
[03:46:18] <zeeshan> im building stainless exhaust manifolds for my car
[03:46:28] <zeeshan> should be a fun project
[03:46:37] <roycroft> i just drilled and tapped a bunch of 5/8" ss round
[03:46:42] <roycroft> fortunately it was 303
[03:46:51] <roycroft> which is the easiest ss i've ever machined
[03:46:59] <zeeshan> never machined that type
[03:47:15] <roycroft> it's much easier than 304
[03:47:26] <roycroft> it's almost like that mild steel with lead
[03:47:52] <roycroft> the holes were 1/4-20, so it wasn't that scary anyway
[03:48:01] <zeeshan> Alloy 303 is a non-magnetic, austenitic stainless steel that is not hardenable by heat treatment. It is the free machining modification of the basic 18% chromium / 8% nickel stainless steel.
[03:48:02] <zeeshan> ah
[03:48:05] <zeeshan> its free machining stainless
[03:48:05] <zeeshan> nice
[03:48:08] <roycroft> yes
[03:48:18] <roycroft> it's really nice to work with, as ss goes
[03:48:32] <zeeshan> fak, maybe i shoulda ordered 303
[03:48:34] <zeeshan> is it weldable
[03:48:39] <roycroft> i believe so
[03:48:43] <roycroft> although i've not welded it
[03:48:55] <zeeshan> Welding Characteristics Not generally recommended, but may be welded with some difficulty May be welded with Alloy 310 electrodes Should be annealed after welding to re-dissolve precipitated carbide
[03:49:09] <zeeshan> maybe thats why i havent seen it for exhaust manifolds
[03:49:13] <zeeshan> ive seen 304, 316 and 321
[03:49:20] <zeeshan> 321 being the most exotic
[03:49:22] <zeeshan> then it goes into inconel
[03:49:29] <zeeshan> which i dont ever want to work with
[03:49:30] <zeeshan> :)

[03:50:35] <roycroft> you should get a little 303 to play with
[03:50:47] <roycroft> you'll start machining it and go "wow, is this really stainless?"
[03:51:06] <roycroft> i've never used 321
[03:51:06] <bobo> PetestuckinTn cast iron , the low strength grade, is nasty dirty. I mean really dirty - sticky dust. might think about a Harbor Freight vacume and also hose it's exaust outside
[03:51:13] <roycroft> but i have used plenty of 304 and 316
[03:51:41] <PetefromTn_> yeah I have machined it before just not this much of it.
[03:51:46] <PetefromTn_> Gotta go Gn8
[03:52:01] -!- PetefromTn_ has quit [Quit: I'm Outta here!!]
[03:52:20] <roycroft> cast iron is supposed to be difficult to weld, but i've had success with it
[03:52:28] <zeeshan> ive welded it fine too
[03:52:29] <roycroft> i preheat it and use nickel rod
[03:52:33] <roycroft> preheating is the key
[03:52:35] <zeeshan> i didnt even do that
[03:52:35] <zeeshan> lol
[03:52:42] <zeeshan> well i preheated
[03:52:44] <zeeshan> but no nickel
[03:52:53] <zeeshan> i used 304L rid
[03:52:54] <zeeshan> rod
[03:53:00] <roycroft> nickel is recommended
[03:53:06] <roycroft> but i think preheating is mandatory
[03:53:20] <zeeshan> nickel rod is expensive :-(
[03:53:20] <roycroft> unless you like to create new cracks while fixing your old cracks
[03:54:42] <roycroft> i think a lot of folks turn on their buzz box, stick whatever rod is handy in the stinger, crank the current up, and do horrible welding
[03:54:48] <roycroft> then complain that cast iron is hard to weld
[03:54:53] <zeeshan> yep
[03:55:08] <zeeshan> just like aluminum is hard to weld :P
[03:55:31] <zeeshan> thats okay
[03:55:32] <roycroft> i'm having a tough time welding ss with my tig welder
[03:55:33] <zeeshan> im glad people think that way
[03:55:39] <roycroft> i just don't have the hang of that yet
[03:55:41] <zeeshan> cause then i can charge more!
[03:55:46] <zeeshan> roycroft: specs
[03:55:48] <zeeshan> of material
[03:55:50] <zeeshan> gun
[03:55:57] <zeeshan> is your weld turning grey
[03:55:58] <roycroft> but the day i got that machine i was welding aluminium nicely
[03:56:31] <roycroft> i'm having trouble getting a steady arc
[03:56:42] <roycroft> and i keep getting the electrode too close and balling it up
[03:56:52] <zeeshan> with aluminum?
[03:56:53] <roycroft> it's entirely operator error
[03:57:01] <roycroft> no, with ss
[03:57:06] <zeeshan> it shouldnt be balling up?
[03:57:13] <zeeshan> youre welding it in dc?
[03:57:16] <roycroft> yes
[03:57:32] <zeeshan> the only time ive had that happen on me
[03:57:41] <zeeshan> was when my tungsten diameter was too small
[03:57:50] <zeeshan> 1/16 " doing 150A
[03:57:51] <roycroft> hmm, i think i'm using 3/32" tungsten
[03:57:57] <zeeshan> hm, thats good
[03:58:05] <roycroft> 2% lanthenated
[03:58:17] <zeeshan> ive tried them all and settled with ceriated
[03:58:18] <zeeshan> its my fav
[03:58:29] <roycroft> i've only used lanthenated and thoriated for ss
[03:58:33] <zeeshan> radiation!
[03:58:39] <roycroft> i'll get some ceriated and check those out
[03:58:42] <roycroft> hey
[03:58:51] <roycroft> i have a vintage aladdin lamp sitting next to me
[03:58:55] <roycroft> made in the early '40s
[03:59:03] <roycroft> the milk glass in it is full of uranium oxide
[03:59:05] <bobo> I alyways thought , Low strength cast iorn welding ,was more of a brazing type result/effect .
[03:59:07] <zeeshan> lol
[03:59:27] <roycroft> it's pretty cool
[03:59:34] <roycroft> it glows nicely under a black light
[03:59:36] <zeeshan> bobo youre right
[03:59:38] <zeeshan> its hard to make it pretty
[03:59:49] <zeeshan> it looks like a blob of crap
[03:59:50] <zeeshan> even with tig
[04:00:28] <bobo> roycroft where do you get the mantal ( sp ?0 for the lamp
[04:01:03] <roycroft> i get them on ebay
[04:01:11] <roycroft> they're also radioactive
[04:01:28] <bobo> so am i
[04:01:32] <roycroft> there are a number of stores that still sell the aladdin stuff
[04:01:42] <roycroft> mainly survivalist stores
[04:01:58] <roycroft> i collect aladdin lamps - i really like them
[04:02:08] <roycroft> i have some going back to the early 1900s
[04:02:20] <roycroft> and some that were made in this century
[04:04:14] <zeeshan> roycroft: have you tried fusion welding stainless
[04:04:16] <bobo> am amazed at how the early Aladdin stuff was made . a lot of sheet metal stampings that is plated
[04:04:21] <roycroft> no, i haven't
[04:04:28] <zeeshan> i think if you can do that
[04:04:30] <zeeshan> you'll master it
[04:04:40] <zeeshan> because its significantly slower than aluminum and steel
[04:04:44] <zeeshan> to get good color out of it
[04:04:51] <roycroft> i just need to practice
[04:04:52] <zeeshan> like 75% slower
[04:05:04] <roycroft> and i haven't had much time to do that
[04:05:08] <zeeshan> well since youre doing aluminum well
[04:05:11] <roycroft> unfortunately i needed to make some parts
[04:05:14] <zeeshan> you got the hand/filler movement good
[04:05:17] <roycroft> so i have parts with goobered welds
[04:05:19] <zeeshan> pedal too
[04:05:29] <zeeshan> with stainless you just gotta slow the heck down :)
[04:05:51] <zeeshan> and breathe that hexavalent chromium
[04:05:53] <roycroft> i think my main problem is getting the current set right
[04:06:11] <zeeshan> i do a lot... of .0625 wall
[04:06:13] <roycroft> and i have to say, while i'm pretty happy with my gtaw machine, there's one thing that really bugs me
[04:06:17] <zeeshan> my welder is set to 48 amps
[04:06:24] <roycroft> the current readout is only accurate while you're welding
[04:06:32] <roycroft> you can't dial the current up to what you want ahead of time
[04:06:49] <roycroft> and i'm busy looking at my part when i'm welding, not looking at the machine
[04:06:58] <zeeshan> im confused?
[04:07:04] <zeeshan> on my welder you set maximum amperage
[04:07:08] <zeeshan> and then adjust it by foot
[04:07:09] <zeeshan> on the fly
[04:07:16] <roycroft> same with mine
[04:07:25] <zeeshan> youre saying the number you set it to
[04:07:26] <roycroft> but all i'm really doing is turning a knob
[04:07:27] <zeeshan> isn't accurate?
[04:07:30] <roycroft> i have no idea what i'm setting it to
[04:07:34] <zeeshan> oh
[04:07:38] <zeeshan> no digital amp meter?
[04:07:47] <roycroft> yes, but it only works when the current is flowing
[04:07:50] <zeeshan> ah
[04:08:11] <roycroft> i have a friend who lives about an hour away who does a lot of ss welding
[04:08:11] <zeeshan> tell a friend to look at it
[04:08:12] <zeeshan> and map it out
[04:08:13] <zeeshan> :)
[04:08:19] <roycroft> he's a fellow homebrewer
[04:08:44] <roycroft> and he's coming down some time next month to check out my new brew system and give me an afternoon of welding instruction
[04:08:51] <zeeshan> nice
[04:08:53] <zeeshan> best way to learn
[04:08:59] <bobo> roycroft try a camera on the meter ?
[04:09:00] <zeeshan> i worked at magnusmotorsports when i was younger
[04:09:05] <roycroft> yeah, i think that's all i
[04:09:07] <zeeshan> and thats how i picked up aluminum welding
[04:09:10] <roycroft> shall need
[04:09:12] <zeeshan> just watching the owner's movement
[04:09:33] <roycroft> bobo: once i figure out where to set the knob the numbers won't matter
[04:09:48] <roycroft> it's just a matter of getting a feel for it
[04:10:10] <zeeshan> if you havent bought this
[04:10:18] <zeeshan> please buy it

[04:10:27] <roycroft> http://www.everlastgenerators.com/product/tig-stick/powertig-250ex
[04:10:29] <zeeshan> itll be the best 28$
[04:10:30] <roycroft> that's the machine i have
[04:10:35] <roycroft> and i have a cooler for it
[04:10:38] <zeeshan> your lungs will love you
[04:10:46] <zeeshan> hexavelent chromium is a carcogenic
[04:10:59] <zeeshan> it rapidly breaks down in the atmosphere
[04:11:05] <roycroft> that's cheap
[04:11:09] <zeeshan> but still , you cant be well protected
[04:11:10] <zeeshan> yea
[04:11:14] <zeeshan> and the catridges are like 6%
[04:11:16] <roycroft> i was thinking of getting a forced air system
[04:11:17] <zeeshan> 6$ to replace
[04:11:21] <zeeshan> it doesnt fog your mask up
[04:11:21] <roycroft> but those are several hundred dollars
[04:11:23] <zeeshan> and its small
[04:11:49] <zeeshan> and you can wash it
[04:11:50] <roycroft> i'll get one
[04:12:54] <roycroft> i bought a really good jackson helmet when i got my new welder
[04:13:10] <roycroft> iirc it was about $300
[04:13:13] <roycroft> it works great
[04:13:26] <zeeshan> good
[04:13:36] <zeeshan> i hate it when people buy a 1000 - 3000$ welder
[04:13:36] <roycroft> three adjustable memory settings for arc, torch, and grinding
[04:13:37] <bobo> if you guys are under 40 go for the forced air stuff
[04:13:41] <zeeshan> and then buy a 40$ helmet
[04:13:58] <roycroft> i value my health
[04:14:11] <zeeshan> just dont weld shit with brake cleaner on it
[04:14:15] <zeeshan> or galvanized
[04:14:19] <zeeshan> and wear a mask for stainless
[04:14:19] <roycroft> i'm the guy who wears hearing protectors and safety glasses while mowing the lawn
[04:14:21] <zeeshan> and i think youll be ok
[04:14:37] <zeeshan> also aluminum dust ive heard gives alzheimers
[04:14:41] <roycroft> if i have to weld galvanized i take it outside and grind the galvinizing off first, with a mask on
[04:14:43] <zeeshan> but that is a controversial subject
[04:14:57] <zeeshan> ive tried that man
[04:15:01] <zeeshan> it still blows up yellow crap
[04:15:01] <roycroft> the aluminium/alzheimer's thing has been pretty thoroughly debunked
[04:15:07] <zeeshan> the lovely smell of death of znic
[04:15:23] <bobo> forced air is the way to go
[04:15:27] -!- jerryitt has quit [Quit: Connection closed for inactivity]
[04:15:32] <zeeshan> its so expensive though bobo
[04:15:37] <zeeshan> the system i was looking at started around 1000$
[04:15:37] <roycroft> i don't weld very often
[04:15:53] <roycroft> if i were doing it on a daily or even regular basis i'd get a forced air system
[04:15:53] <zeeshan> i keep a small breeze
[04:15:55] <zeeshan> and ventilate
[04:16:04] <roycroft> yes, i always make sure i have ventilation
[04:16:16] <zeeshan> i wish you could just blow air at the weld area
[04:16:18] <zeeshan> like at 290132093128 cfm
[04:16:21] <zeeshan> but it takes the argon away with it
[04:16:22] <roycroft> and if i'm going to do a lot of welding i put a fan in the door at one end of my shop
[04:16:24] <zeeshan> and you get a crap weld
[04:18:48] <roycroft> what i really like about my jackson helmet is that i was able to get magnifying lenses to fit inside it, so i don't have to wear reading glasses to weld
[04:19:10] <roycroft> i know some of the other brands have that feature in their higher end helmets
[04:19:17] <roycroft> for us old people that's really nice
[04:19:56] <bobo> also put a bib on the helment bottom keep thu UV off the throat
[04:20:37] <roycroft> when i bougt the welder i got a bib, and a nice welding jacket, and a couple pair of tig gloves
[04:20:54] <roycroft> i figured if i was spending $3k on welding gear i could spend another $500 on safety gear
[04:21:42] <roycroft> i don't know how people worked before we had auto-darkening helmets
[04:21:59] <roycroft> and i know there are a lot of experienced welders out there who still don't use the auto-darkening ones
[04:22:09] <roycroft> they do the neck flip thing
[04:22:51] <bobo> alright roycroft it's usens telling zeeshan to get a throat bib for his helment
[04:22:58] <zeeshan> roycroft: i just saw the link
[04:23:02] <zeeshan> everlast is like 30 min from me
[04:23:06] <zeeshan> they have good welders
[04:23:08] <roycroft> yes
[04:23:11] <zeeshan> i have their plasma
[04:23:13] <roycroft> people poo poo them all the time
[04:23:21] <roycroft> but i think they make decent stuff
[04:23:23] -!- jvrousseau has quit [Quit: My Mac has gone to sleep. ZZZzzz…]
[04:23:23] <roycroft> yes, it's from asia
[04:23:29] <zeeshan> the guy said they were designed in canada/usa
[04:23:30] <roycroft> so are the blue and red inverters
[04:23:35] -!- Tecan has quit [Quit: Live Long And Phosphor!]
[04:23:36] <zeeshan> nahh
[04:23:41] <zeeshan> miller is purely usa
[04:23:46] <zeeshan> lincoln is usa/italy/canada
[04:23:50] <roycroft> everlast use german output transistors though
[04:24:15] <roycroft> i'm pretty sure both miller and lincoln have some asian made stuff
[04:24:26] <zeeshan> my only problem with everlast
[04:24:27] <zeeshan> for a welder is
[04:24:29] <zeeshan> replacement parts
[04:24:31] <roycroft> but at the end of the day it really doesn't matter
[04:24:38] <zeeshan> lincoln/miller -- everyone has their boards
[04:24:41] <zeeshan> easy to fix
[04:24:43] -!- bilboquet has quit [Quit: Quitte]
[04:24:44] <roycroft> i thought the everlast was a good value
[04:24:44] <bobo> zeeshan if they are 30 min away that sure beats buying a Linclon inverter
[04:25:00] <zeeshan> bobo: boards come from china though :/
[04:25:10] <zeeshan> like lincoln/miller/esab are all over thep lace
[04:25:15] <zeeshan> its like mikron
[04:25:15] <roycroft> i think of them as the grizzly or jet of welder importers
[04:25:17] <zeeshan> theyre dead
[04:25:19] <zeeshan> you cant get their parts
[04:25:19] <zeeshan> lol
[04:25:25] <roycroft> their stuff is kind of like the other asian stuff
[04:25:33] <zeeshan> yea
[04:25:35] <zeeshan> but a lot better!
[04:25:42] <roycroft> but a little better design, and a lot better manufacturing tolerances
[04:26:02] <roycroft> hf sell welders a lot cheaper
[04:26:10] <roycroft> i think they're quite useful
[04:26:23] <roycroft> if you need to prop your shop door open for ventilation while you're welding
[04:26:41] <roycroft> with your real welder
[04:27:17] <roycroft> when i was shopping for my welder i perused the welding forums
[04:27:36] <roycroft> it was apparent right away that the folks who were badmouthing everlast the most were xenophobic racists
[04:27:46] <roycroft> so i just ignored them
[04:28:45] <zeeshan> lol
[04:28:59] <roycroft> so when i bought my welder, it arrived and i was ready to play with it
[04:29:08] <roycroft> but it was supposed to come with an argon regulator, and that was missing
[04:29:15] <roycroft> so i called my sales guy
[04:29:15] <zeeshan> its just like with everything
[04:29:18] <zeeshan> some things are good, some are bad
[04:29:29] <zeeshan> people shit talk nicholson files
[04:29:32] <zeeshan> that are made in mexico
[04:29:32] <bobo> I got a HF inverter welder , was great while it lasted . when the IGBT went gota Linclon AC inverter
[04:29:34] <roycroft> it turns out that he and the rest of management were at a trade show in las vegas at the time
[04:29:35] <zeeshan> they work REALLY good.

[04:29:54] <roycroft> but he called me back from the trade show floor about 10 minutes after i left him the voicemail
[04:29:55] <zeeshan> bobo: nice
[04:30:09] <roycroft> he got my info, and the next day a regulator was at my door
[04:30:40] <zeeshan> as much as i want an inverter style tig
[04:30:43] <zeeshan> for the frequency control
[04:30:45] <zeeshan> i dont think ill get one
[04:30:51] <zeeshan> cause if it blows up, i dont know how to fix it
[04:30:54] <roycroft> and the fact that you can move it easily? :)
[04:30:56] <zeeshan> too much crazy stuff going on in there
[04:31:03] <roycroft> yeah i can get that
[04:31:08] <zeeshan> you dont really tig on the go though
[04:31:09] <roycroft> and you use the thing to generate revenue
[04:31:10] <zeeshan> maybe a roll cage
[04:31:17] <roycroft> i don't
[04:31:24] <roycroft> if mine breaks, it has a 5 year warranty
[04:31:30] <roycroft> and i can wait for a repair
[04:31:32] <zeeshan> ive had mine for 10 years :d
[04:31:35] <roycroft> you lose money if you do that
[04:31:47] <zeeshan> i do it as a side hobby

[04:32:37] <roycroft> i bought a plasma cutter at the same time as i got the gtaw machine
[04:32:42] <roycroft> i've hardly used it, but it works really well
[04:32:43] <zeeshan> which one
[04:32:55] <roycroft> a cheap one
[04:32:57] <zeeshan> ah
[04:32:58] <roycroft> one moment
[04:33:14] <zeeshan> http://www.everlastgenerators.com/product/plasma/powerplasma-50
[04:33:16] <zeeshan> thats whati have
[04:33:20] <roycroft> yes that one
[04:33:25] <zeeshan> works good
[04:33:28] <roycroft> you plug it in
[04:33:30] <zeeshan> my only complaint is
[04:33:30] <roycroft> hook up the air
[04:33:32] <roycroft> cut things
[04:33:34] <zeeshan> that it uses air
[04:33:40] <zeeshan> i wanna make it work with nitrogen
[04:33:54] <zeeshan> lets say you cut aluminum with it
[04:34:01] <zeeshan> it forms a crappy shitty oxide layer at the edge
[04:34:11] <zeeshan> you gotta grind of like 1/8 of it
[04:34:12] <zeeshan> "
[04:34:15] <zeeshan> to get a good weld after
[04:34:17] <roycroft> does it not work with nitrogen?
[04:34:18] -!- ve7it has quit [Remote host closed the connection]
[04:34:21] <zeeshan> i havent tried
[04:34:23] <bobo> zeeshan why not stop over to everlast and ask where they get the boards fixed ? could be a income thing for someone
[04:34:24] <zeeshan> i dont see why it wouldnt
[04:34:24] <roycroft> does it need oxygen for the plasma?
[04:34:29] <roycroft> air is mostly nitrogen
[04:34:44] <zeeshan> bobo: they wont reveal that info haha
[04:35:00] <roycroft> it's a really competetive business
[04:35:46] <roycroft> the guy at everlast also gave me a really good deal
[04:35:59] <roycroft> i made up a spreadsheet with everything i wanted
[04:36:15] <roycroft> decided how much i wanted to pay for everything, and sent it to him
[04:36:22] <roycroft> and told him i wanted free shipping
[04:36:34] <roycroft> he filled in the numbers the way it worked for him, which was a little weird
[04:36:44] <roycroft> some things he had to sell at list, some he could give a big discount
[04:36:47] <roycroft> but he met my number
[04:36:54] <roycroft> which was about $500 under list, iirc
[04:37:09] <zeeshan> nice!
[04:37:24] <zeeshan> another damn machine that's green
[04:37:28] <zeeshan> goddamn green machines
[04:37:49] <roycroft> it matches my lawn mower
[04:37:52] <zeeshan> lol
[04:38:09] <roycroft> it's a lawnboy, not john deere
[04:38:37] <bobo> green for envy
[04:40:33] <roycroft> so do spiral taps work for hand tapping?
[04:41:11] <roycroft> it seems they would have better chip clearance than standard straight taps
[04:41:22] <roycroft> and even when hand tapping that's a problem
[04:41:28] <zeeshan> ive used it by hand
[04:41:31] <zeeshan> but they seem fragile
[04:41:34] <zeeshan> to side loading
[04:41:47] <roycroft> yeah, i can see that
[04:42:07] <zeeshan> i like how the chip
[04:42:09] <zeeshan> comes out
[04:42:12] <zeeshan> and doesnt go in
[04:42:19] <zeeshan> its very useful for tapping on the car.
[04:42:20] <roycroft> in larger sizes, say 3/8" or larger, they're probably pretty sturdy
[04:42:22] <zeeshan> like an oil pan
[04:42:43] <roycroft> but for smaller ones side loading would be a concern
[04:43:26] <roycroft> what about hand tapping with forming taps?
[04:43:30] <bobo> Oh ! Digital Machinist --Vol10,# 1 =spring neat article on scales having sine wave output ----- converting to square wave via "ic-Haus " chip
[04:43:30] <roycroft> is that reasonably doable?
[04:43:56] <zeeshan> i have done thread forming taps by hand
[04:44:01] <zeeshan> they are crazy strong :)
[04:44:08] <roycroft> the chips go nowhere if you use one of those
[04:44:14] <zeeshan> there are no chips
[04:44:16] <roycroft> right
[04:44:16] <zeeshan> it deforms
[04:44:19] <roycroft> which is why they go nowhere
[04:44:26] <zeeshan> actually you make a good point
[04:44:30] <zeeshan> i didnt think about that for oil pan tapping
[04:44:32] <zeeshan> that makes more sense!
[04:44:37] <zeeshan> Good man!
[04:44:57] <roycroft> sometimes i accidently get something right :)
[04:45:08] <zeeshan> i have to tap my oil pan
[04:45:11] <zeeshan> but the problem is
[04:45:15] <zeeshan> the drill chips :)
[04:45:22] <zeeshan> so i guess ill still have to pull it
[04:46:00] <roycroft> edm

[04:49:23] <bobo> the scale article is very good
[04:50:39] <zeeshan> im studying for my exam tomorrow
[04:50:46] <zeeshan> lol one of the things he taught is
[04:50:47] <zeeshan> us
[04:50:54] <zeeshan> "Center drilling - not very common anymore"
[04:51:02] <zeeshan> "Carbide drills are used directly"
[04:51:07] <zeeshan> :(
[04:51:15] <tiwake> wait what
[04:51:16] <zeeshan> damn industry and their big wallets
[04:51:29] <zeeshan> hes saying that its pointless to center drill
[04:51:30] <tiwake> what does center drilling mean?
[04:51:31] <zeeshan> before drilling
[04:51:38] <tiwake> oh
[04:51:50] <zeeshan> http://upload.wikimedia.org/wikipedia/commons/d/df/CenterDrills123456.jpg
[04:51:51] <zeeshan> those things
[04:51:55] <tiwake> spot drill thing so the drill does not wonder
[04:52:01] <tiwake> yeah
[04:52:02] <tiwake> derp
[04:52:06] <tiwake> (I knew that)
[04:52:28] <zeeshan> i just felt sad when he was saying that
[04:52:33] <zeeshan> cause i always use center drilling
[04:52:34] <tiwake> donno what industry they are talking about, but I've been a machinist for ~10 years now and use them flank tons
[04:52:43] <zeeshan> cnc production environment
[04:52:54] <bobo> anyway --what's with the slant bed lathe ? bolt the sucker to the ceiling ! gives you more floor space too
[04:52:55] <tiwake> yeah, CNC
[04:53:03] <tiwake> why would you not use one?
[04:53:03] <zeeshan> bobo: ROFL
[04:53:11] <zeeshan> tiwake: cycle time
[04:53:19] <tiwake> no I mean
[04:53:28] <tiwake> you cant get away from using one... lol
[04:53:39] <zeeshan> you can if youre drilling flat stuff
[04:53:44] <zeeshan> cause carbide is stiff enough to not wanter
[04:53:44] <tiwake> dills like to drill sideways
[04:53:46] <zeeshan> *wander
[04:53:59] <tiwake> who has the money for solid carbide drills?
[04:54:04] <zeeshan> thats why im saying!
[04:54:10] <tiwake> I guess spade drills are not necessary
[04:54:12] <zeeshan> damn industries with their big wallets
[04:54:21] <zeeshan> did you know
[04:54:28] <zeeshan> roughly 5% of the manufacturing cost is tooling
[04:54:29] <zeeshan> lol
[04:54:31] <tiwake> I use spade drills a fair amount, and typically don't center/spot with them
[04:54:46] <roycroft> you folks on this channel have converted me to using spot drills, not center drills, for locating drill holes
[04:54:57] <roycroft> they work so so much better
[04:55:03] <zeeshan> i use both
[04:55:04] <zeeshan> i dont know why
[04:55:10] <tiwake> depends on the thing
[04:55:11] <zeeshan> i guess cause i only have 2 size spot drills
[04:55:16] <zeeshan> oh i know why
[04:55:20] <zeeshan> for drilling centers for the lathe tail stock
[04:55:32] <tiwake> center drills are ... yeah
[04:55:35] <roycroft> yes, but that's a different operation
[04:55:39] <zeeshan> but i still use it to start a hole
[04:55:55] <roycroft> you're drilling for centers, not for drills
[04:56:02] <zeeshan> no even for drills
[04:56:04] <zeeshan> i use it
[04:56:14] <zeeshan> my spot drill is 1/2"
[04:56:16] <zeeshan> i think thats why
[04:56:21] <tiwake> today I machined some airplane parts and use a center drill
[04:56:23] <zeeshan> if i wanna drill a 1/4" hole
[04:56:26] <roycroft> i bought several spot drills
[04:56:29] <zeeshan> it might wander too much (thats what it feels liek for me)
[04:56:36] <zeeshan> nice tiwake
[04:56:46] <tiwake> struts
[04:56:57] <roycroft> it was getting on time to replace my center drills
[04:56:59] <zeeshan> are you ssi's friend? :D
[04:57:03] <roycroft> and i'm not using my little lathe much
[04:57:03] <zeeshan> hes our resident air craft guy
[04:57:10] <tiwake> no idea who that is
[04:57:25] <roycroft> so i figured i'd keep my mostly worn center drills for the lathe, and get spot drills for other uses
[04:57:36] <tiwake> what I made is for a company in seattle.... *shrug*

[09:50:24] <Cromaglious_> CSR for many things... short term is very bad. If I study it enough it starts sticking
[09:52:01] <Cromaglious_> like the other night with r2e4 in using G61 and G63 I remembered it was around G6x something with the constant velosity
[09:52:25] <XXCoder> it sucks when only 3 am option for snacks are walmart or fast food
[09:52:39] <XXCoder> dont feel like fast food and I will never shop at walshit

[10:59:44] <jthornton> anyone ever make a telescoping cover for a 6" mill vise like this
http://www.dynatect.com/uploads/images/Telaflex-Steel-WayCover3.jpg
[11:03:10] <XXCoder> 6 in?
[11:03:17] <XXCoder> wouldnt leather sheet work fine
[11:04:10] <jthornton> what about the coolant?
[11:04:20] <XXCoder> ah yea
[11:04:45] <XXCoder> that probably is makable with anyone with bender
[11:04:47] <jthornton> the piece of spring steel they give you is too long usually
[11:04:49] <XXCoder> you could even make one
[11:05:05] <jthornton> I wonder if you even need to bend them?
[11:05:17] <XXCoder> minium 2 bends
[11:05:37] <XXCoder> more if you want good finish edges

[11:07:09] <XXCoder> http://www.ebay.com/itm/like/310576756754?lpid=82&chn=ps specifically for mill
[11:07:31] <XXCoder> with sheet in front to mak chip cleaning much easier
[11:08:37] <jthornton> I have a pair of those from an AC
[11:09:04] <jthornton> those are hard to clean and stay full of chips
[11:09:15] <XXCoder> hence the sheet in front :)
[11:09:38] <XXCoder> brigeport mill I used to run had one. sure makes it easy.
[11:10:04] <jthornton> a spring roll would be nice as you could open the vise all the way

[13:54:04] <JT-Shop> that I don't know

[13:57:13] <mutley> trying to tune it up, setting microstepping etc, but i get this "banging" that i can feel through the machine and in particular through the leadscrews when doing circular motion
[13:57:24] <mutley> im just uploading a video,

[14:15:55] <mutley> ok heres the vid
[14:16:37] <mutley> the noise actually isnt that audible, you can just hear it in parts toward the end, its 30 second clip, but you can see the effect, by the piece of counduit over the gantry shaking
[14:16:38] <mutley> https://www.youtube.com/watch?v=31v5tujdygk
[14:17:25] <mutley> im also playing around with icrostepping settings, this sounds to be singing a little too much,
[14:17:37] <mutley> in that vid its 2560 steps per mm
[14:17:46] <mutley> which is admittedly prob too high
[14:18:21] <mutley> but im tying to snuff out this banging noise, you can feel it through the machine, and particularly on the screws, it is eminating from the motors
[14:18:53] <mutley> its almost like a missed step, and its not just during direction changes,

[14:26:37] <pcw_home> yes, and they happen at a ~ constant rate regardless of motor speed
[14:27:33] <mutley> pcw_home: mmm ok interesting, when you say costant rate, you mean like a drum beat constant rate, or constant rate of motion on the axis
[14:28:08] <mutley> mind you going in circular motion it wont be constant speed at all
[14:28:12] <archivist> ssi I obtained a pile of microfiche of manuals service info etc for small planes, ex skip CAA
[14:28:36] <mutley> and come to think of it, when i job the axis, the movement is fine and smooth with no banging noise
[14:28:37] <cradek> mutley: did you say it's only while doing circles?
[14:28:46] <pcw_home> constant thump rate even during circular motion suggest bad pulse stream to me
[14:28:47] <mutley> cradek: yes
[14:29:13] <pcw_home> bad gcode/interpreter?
[14:29:15] <cradek> if you put your hand on it can you tell which motor is thumping?
[14:29:29] <cradek> what software is it?
[14:29:51] <mutley> pcw_home: ok, sounds like a possibility, and what would be the cause of something like that, bad stepper wiring or more control based
[14:30:01] <mutley> cradek: can feel it on both X and Y
[14:30:17] <pcw_home> control would be my guess
[14:30:23] <mutley> cradek: its planetcnc
[14:31:01] <pcw_home> circle made from line segments and improper blending?
[14:31:04] <cradek> oh I have no idea what that is

[14:31:37] <cradek> http://forum.planet-cnc.com/viewtopic.php?f=6&t=1342
[14:32:00] <cradek> there are some options about arcs
[14:32:22] <cradek> but you should probably use linuxcnc instead
[14:32:26] <mutley> ill say i kind of inherited the control system that came with the machine, it was a ready runner, but im not so confident in it tbh
[14:32:43] <mutley> cradek: yea i see those,
[14:32:55] <cradek> you could scope the pulse output and see exactly what the breakage is

[14:38:41] <mutley> im just looking in settings, it does seem like something to do with arc control

[14:43:21] <archivist> it will take a "while" to catalogue and add to my online index
[14:44:47] <mutley> ha i think ive just nailed
[14:45:26] <mutley> pcw_home: you gve me the lead i needed
[14:46:07] <mutley> helix interpolation disabled
[14:46:16] <mutley> unchecked that and smooth as silk
[14:46:33] <mutley> and im reaching the feedrtes that were set
[14:46:38] <cradek> so yeah anyway, use linuxcnc
[14:46:56] <cradek> "we couldn't get this to work so we added a checkbox"
[14:46:58] <mutley> cradek: i do intend to go down that route
[14:47:13] <mutley> cradek: yea thats what i have here
[14:47:48] <mutley> helix interpolation is now active cradek, it was off
[14:48:15] <mutley> not sure i recall actually touching it either, and this has been an unnoticed problem for a little while
[14:49:26] <mutley> what would determine init and accelertion speeds on a cnc, and what would one expect for a machine like in that vid
[14:49:41] <mutley> by init, im presuing thats jerk setting,
[14:49:53] <mutley> although i guess my own jerk value is quite high atm ;p
[14:50:36] <mutley> crrently in the settings, init/jerk is set to 0 and accell is 25
[14:51:09] <mutley> assuming mms as the unit
[14:53:07] <mutley> or is that like asking how long is this piece of string
[14:53:28] <mutley> major influences would be machine rigidity and tool bits used?
[14:54:42] <mutley> and yes, i am being lazy for a quick informative idea, but will be doing more research into this
[14:54:50] <mutley> was just wondering
[14:55:03] <malcom2073> Heya mutley
[14:55:27] <mutley> heya malcom2073
[14:55:32] <mutley> how goes
[14:55:38] <malcom2073> Goes great, yourself?
[14:55:59] <malcom2073> Saw the video, new toy? Looks nifty
[14:56:03] <mutley> gahhh, this cnc machine and its gremlins (but i suspect ore a user issue;p)
[14:56:41] <mutley> nah had it a while, it just doesnt get much use, and i think an (auto) firmware update set a checkbox on something that just screwed me
[14:57:14] <malcom2073> Yowch heh
[14:57:16] <mutley> but pcw_home and cradek got me on the right path to spot it
[14:58:04] <malcom2073> Awesome
[14:59:01] <mutley> so, one last question then, got a check box here "split arcs"
[14:59:06] -!- kwallace has quit [Ping timeout: 276 seconds]
[15:00:27] <cradek> so you have four possible combinations of options for "try to get arcs to work right"
[15:00:35] <cradek> we have no idea what those do
[15:00:53] <cradek> maybe you should use linuxcnc :-)
[15:00:57] <mutley> yea i guess its boils down to how the guy coded it

[16:00:51] -!- deanputney has quit [Remote host closed the connection]
[16:02:20] <mutley> jthornton: but yes i do agree, however i have been batting a problem with a 1mm bit, 13mm deep, giving me out of round gear profiles, part of the issue was deflection of the bit even though running it at very low feeds
[16:03:05] <mutley> but ive also just found antoher setting, path approximation was set to 0.2, and my out of round was guess what, 0.2ish
[16:03:50] <mutley> so now i do the first part of the cut with a 10mm long bit, and then the last 3mm with the 13mm deep bit but uch slower feed
[16:04:09] <mutley> the tooth profile is 13mm deep hence the need for the bith depth
[16:05:35] <JT-Shop> mutley, have you read this short chapter in the lovely manual?
http://www.linuxcnc.org/docs/html/common/User_Concepts.html
[16:06:03] <JT-Shop> yes, tool flex can not be known by the control software...
[16:06:30] -!- karavanjo has quit [Quit: karavanjo]
[16:07:10] <mutley> so forgive me for asking, but just to confirm, linuxcnc is control software not path generation software
[16:07:40] <archivist> mutley, you are cutting gears the wrong way to get a good form
[16:08:01] <mutley> archivist: yea i get that
[16:08:31] <mutley> its not the ideal, especially for these particular gears, but with care you can get quite a good result
[16:08:52] <mutley> archivist: although what would you suggest instead? i only have the cnc at my disposal
[16:09:12] <mutley> proper hobber machine?
[16:09:42] <archivist> proler gear cutters and a rotary controlled by the cnc
[16:09:47] <archivist> proper
[16:10:38] <mutley> archivist: got a link to an example??
[16:10:44] <archivist> hobbing being better than gear milling
[16:11:02] <mutley> id imagine this is major money though
[16:12:33] <archivist> a 4th axis is not too bad
[16:15:21] <archivist> the money is in cutters usually
http://www.archivist.info/cnc/target.php
[16:16:40] <archivist> being a crap picture but one of the few showing a form cutter and the job

[16:19:13] <mutley> ive got a rotary table, albeit a manual one here
[16:19:25] <mutley> but i wouldnt call it a high end one either
[16:20:13] <mutley> are you suggeting to clamp the gear to the rotary, clamp rotary to bed of cnc, and ut cutting wheel into the spindle on a shaft?
[16:20:35] <mutley> or another setup, or a specific machine especially for gear cutting
[16:20:55] <mutley> the problem is, one of the gears is a one piece compound gear
[16:20:55] <archivist> cutter costs mount up when you need about 7 for one gear DP/MOD size and any number of teeth, hobbing cutters cover any number of teeth on one cutter
[16:21:29] -!- md-2 has quit [Quit: Leaving...]
[16:21:31] <archivist> press fit two gears together
[16:21:49] <mutley> archivist: that is an option, im cutting them out of a PET material
[16:22:02] <mutley> one of them anyway, the other is out of nylatron
[16:22:25] <mutley> the originals are injection moulded, which might help explain a bit
[16:23:27] <archivist> you can make that type of gear from solid by shaping too (turn to od first)
[16:25:25] -!- Thomaxo__ has quit [Remote host closed the connection]
[16:25:42] <mutley> yea i have thought about turning, id need to get a bigger chuck for my lathe first, or a bigger lathe
[16:25:56] <mutley> atm i mill out from 30mm thick sheet
[16:26:37] <mutley> gear stands 29mm tall, so the thick sheet/block does act as a good hold down

[21:35:00] <Computer_Barf> is all that a fancy way of saying that , here are some spare 5v / gnd pins in case you need it
[21:36:25] <PCW> it saying that if you power it with your 25A 5V PC supply it will not burn up your wires in the event of a short
[21:38:07] <Computer_Barf> well the note was concerning some gnd and 5v line that are next to the +/- dir and pull
[21:38:59] <PCW> some step drives have common anode OPTOs (so you need +5V)

[21:39:28] <Computer_Barf> ahh that makes sense. I figured it was just an extra supply for situations where you might need it

[21:40:24] <PCW> some have independent OPTOs so you can drive them differentially for better noise immunity
[21:41:06] <PCW> yeah those are really +DISABLE and -DISABLE
[21:41:18] <PCW> a bad idea
[21:42:10] <PCW> you should have to supply a signal to enable a drive (so a broken connection disables the drive)
