06:28 PM zhanx_ is now known as zhanx
10:34 PM Tom_L: it was a sad day today
10:34 PM rue_mohr: ?
10:34 PM Tom_L: i went to my local iron scrap yard today to drop off the old water heater
10:34 PM rue_mohr: MM?
10:34 PM rue_mohr: there was a sherline?
10:34 PM Tom_L: found out the guy retired and sold out to a larger (less friendly) company
10:35 PM rue_mohr: oh no
10:35 PM Tom_L: so kiss my iron scrap goodbye
10:36 PM rue_mohr: well track him down and tell him he has to open a new yard!
10:36 PM Tom_L: they still sell scrap but it's far more organized
10:36 PM Tom_L: and i found out an old friend died recently that i'd lost contact with
10:37 PM rue_mohr: :(
10:39 PM Tom_L: he was into robotics and stuff but last few years he'd kinda distanced himself from ppl
10:40 PM rue_mohr: WAS IT SOMETHING LIKE CANCER?
10:40 PM rue_mohr: SORRY
10:40 PM rue_mohr: caps stuff in other window
10:40 PM Tom_L: o
10:40 PM Tom_L: i'm not sure
10:41 PM Tom_L: i know he had been loosing his eyesight and i think that really bothered him
10:44 PM rue_mohr: it would be nice if we just didn't age
10:46 PM Tom_L: he was 76
10:46 PM rue_mohr: I wanna be a robot ....
10:47 PM Tom_L: far more lonely than you are now
10:47 PM Tom_L: i hug my pets every day. i can count on them
10:48 PM Tom_L: the rest can kiss my ass
10:51 PM rue_mohr: your still working eh?
10:51 PM Tom_L: of course
10:53 PM rue_mohr: seen people stop working and go batty
10:53 PM Tom_L: finally tossed my first pc today
10:53 PM rue_mohr: :)
10:53 PM rue_mohr: still have my apple IIe
10:53 PM Tom_L: pulled the st-238 from it cause i wasn't sure what was on it
10:53 PM rue_mohr: I have a loyalty to hardware that was good
10:53 PM Tom_L: actually that wasn't the first one
10:53 PM Tom_L: but the first one was in the pile
10:54 PM Tom_L: monochrome monitor ( orange )
10:54 PM rue_mohr: orange!
10:54 PM Tom_L: whatever shade that was
10:54 PM rue_mohr: I think I started 386 world with a vga
10:54 PM rue_mohr: IBM
10:54 PM Tom_L: 8088
10:55 PM rue_mohr: I went from apple IIe to 386-25
10:55 PM rue_mohr: wow was that a leap
10:55 PM Tom_L: commodore before that of some sort
10:55 PM Tom_L: 64 then the portable
10:55 PM Tom_L: lugable whaever...
10:56 PM Tom_L: that was where i started my business database
10:56 PM Tom_L: then ported it to the pc
10:56 PM Tom_L: all on 5" floppies
10:56 PM rue_mohr: :)
10:57 PM Tom_L: single sided iirc
10:57 PM Tom_L: anyway. all the junk from the basement is pretty well gone now
10:57 PM Tom_L: i bet the trash man hated me today
10:58 PM rue_mohr: hows the repairs?
10:58 PM Tom_L: done
10:58 PM Tom_L: carpet in, furniture back in
10:59 PM Tom_L: alot gone
10:59 PM Tom_L: good time to clear junk out
11:00 PM Tom_L: gotta make sure my kid gets up at 3 so i better go sleep for a couple hrs
11:00 PM rue_mohr: dont die anytime soon eh?
11:01 PM Tom_L: out of my hands
11:01 PM Tom_L: wasn't in the plans though
11:02 PM rue_mohr: having issues deciding on a z slider for the cnc
11:02 PM Tom_L: you want it rigid
11:02 PM rue_mohr: yep
11:03 PM rue_mohr: I'm indecisive between slide bushings or bearing rollers
11:03 PM rue_mohr: and if I weren't, I'd have assembled something by now :)
11:03 PM Tom_L: make em both
11:03 PM Tom_L: toss the looser
11:04 PM rue_mohr: :) I ahve 8 different design ideas
11:04 PM Tom_L: i started one and scrapped it
11:04 PM rue_mohr: such seems the way
11:05 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Steel6.jpg
11:05 PM Tom_L: that one never made it
11:05 PM rue_mohr: ah yes
11:06 PM rue_mohr: that tucking of the motor was a good one
11:06 PM Tom_L: part of it did
11:06 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/StepperMount1.jpg
11:06 PM Tom_L: that?
11:06 PM rue_mohr: the bridge over it
11:07 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Z_Column2.jpg
11:07 PM Tom_L: sorta inbetween designs there
11:08 PM Tom_L: but that z column worked out and the base steel got replaced with a new piece i found at the scrap
11:08 PM rue_mohr: yep
11:08 PM Tom_L: that one was all rusty and pitted
11:08 PM rue_mohr: hah, own out gloves
11:09 PM rue_mohr: I bought some new tig gloves like 3 weeks ago and there is already holes in em
11:09 PM rue_mohr: burned myself once already
11:09 PM Tom_L: i've got several of those and some heavy ones
11:13 PM Tom_L: as crappy as that Z column looks it turned out really straight and flat
11:13 PM Tom_L: i was surprised i didn't have to mill it flat for the rails
11:15 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Welding/Z_Column_tack1.jpg
11:15 PM Tom_L: i think i spend a good couple hours making sure those were flat before i did those tacks
11:16 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Welding/Z_Column_tack2.jpg
11:17 PM Tom_L: those were done before i figured out the shield gas hose was loose
11:17 PM rue_mohr: I'm into shims
11:17 PM Tom_L: i didn't shim that but i did shim X
11:18 PM rue_mohr: I have 3 abandoned weling bottles now
11:18 PM Tom_L: and a little underneath that Z plate to make it perp to the base
11:18 PM Tom_L: i trade mine in
11:18 PM Tom_L: but i haven't emptied one in a long time
11:18 PM Tom_L: i've got 2 small ones
11:18 PM rue_mohr: yea, every so often their abandoned
11:18 PM rue_mohr: I seem to be collecting them
11:19 PM rue_mohr: need to check dates
11:19 PM rue_mohr: or get one recart'd
11:19 PM rue_mohr: cert'd
11:19 PM Tom_L: i let them worry about that
11:19 PM rue_mohr: zhanx, your heart still beating dude?
11:19 PM Tom_L: with the small ones you can do that
11:19 PM rue_mohr: M
11:19 PM rue_mohr: I think
11:19 PM Tom_L: no idea what size these are
11:19 PM rue_mohr: their company tankes
11:20 PM rue_mohr: one is air liquide and the other is union carbide
11:20 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Welding/Miller.jpg
11:20 PM Tom_L: sits behind that
11:20 PM Tom_L: no taller
11:20 PM rue_mohr: and the other I cant recall
11:21 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Welding/test_bead2.jpg
11:21 PM Tom_L: fixed the leak and things got better
11:21 PM rue_mohr: much
11:21 PM Tom_L: that was a test run
11:24 PM rue_mohr: I should play with the wirefeed again
11:24 PM zhanx: yep
11:25 PM rue_mohr: for steel, wirefeed its co2 or argon?
11:25 PM rue_mohr: zhanx, :)
11:25 PM Tom_L: i use a tri mix
11:25 PM rue_mohr: ugh
11:25 PM Tom_L: but you can use co2
11:25 PM zhanx: my back has been killing me
11:25 PM Tom_L: argon is for aluminum
11:25 PM rue_mohr: k
11:25 PM rue_mohr: last tank I got was argon
11:25 PM Tom_L: and reverse polarity
11:25 PM rue_mohr: but I think the gasses are reversed for tig
11:25 PM Tom_L: iirc
11:26 PM Tom_L: i wouldn't know why
11:26 PM rue_mohr: so, argon for tig? I'm sure it crosses back and forth and I'm just confused
11:26 PM rue_mohr: NEED CHART!
11:27 PM zhanx: real internets will be here tomorrow!!!
11:27 PM rue_mohr: aaah
11:27 PM rue_mohr: k
11:27 PM rue_mohr: for sure this time?
11:27 PM zhanx: between 730 am and 1130 so yea
11:27 PM Tom_L: https://www.thefabricator.com/article/consumables/simplifying-shielding-gas-selection
11:28 PM rue_mohr: do they just say trimix down the whole column?
11:28 PM Tom_L: heh
11:29 PM rue_mohr: :)
11:29 PM rue_mohr: took that long to load too
11:29 PM Tom_L: bottom one is co2 for mild steel
11:29 PM rue_mohr: gas tig arc welding?
11:29 PM rue_mohr: gas tungsten, arc welding
11:30 PM Tom_L: dunno
11:30 PM Tom_L: FCAW
11:30 PM Tom_L: whatever that is
11:30 PM rue_mohr: and gas metal arc welding (mig) ?
11:30 PM rue_mohr: hahha
11:30 PM rue_mohr: we need a simpler chart!!!
11:30 PM rue_mohr: :))))))
11:30 PM Tom_L: i know you can use co2
11:30 PM rue_mohr: rofl
11:30 PM rue_mohr: well gtaw is ar across the board
11:31 PM Tom_L: https://www.lincolnelectric.com/en-us/support/process-and-theory/Pages/common-shielding-gases-for-arc-welding.aspx
11:32 PM Tom_L: looks like argon works for about anything on tig
11:32 PM rue_mohr: yea, tig is AR across the board
11:32 PM rue_mohr: ig is mix
11:32 PM rue_mohr: mig is mikx
11:32 PM rue_mohr: mig is mix
11:32 PM rue_mohr: }:| keybaord....
11:33 PM Tom_L: i got a bottle of argon once to try aluminum
11:34 PM Tom_L: but i bet my hose was leaking then too and it didn't work so well so i gave up
11:34 PM Tom_L: i bet it would do ok if i tried again
11:34 PM Tom_L: but i'm not gonna buy an argon bottle
11:34 PM rue_mohr: !bookmark tig=Argon Mig, carbon steel = co2 aluminum = argon
11:35 PM Tom_L: or tri mix on mild steel
11:35 PM rue_mohr: well, I get questions like what mix ratio?
11:35 PM rue_mohr: so just co2 is easier
11:35 PM Tom_L: co2 is cheaper
11:36 PM Tom_L: 75 25 or something close to that
11:36 PM Tom_L: i forget what the 3rd gas is
11:36 PM Tom_L: but it's like 3%
11:36 PM rue_mohr: hmm
11:37 PM rue_mohr: the bottle I used for tig was brown
11:37 PM rue_mohr: but the new bottle I got is green and its argon
11:37 PM Tom_L: TRI-MIX � 66.1% Argon � 33% Helium � 0.9% Co2
11:37 PM rue_mohr: I can remember argon | co2
11:38 PM Tom_L: This tri-mix blend is used for short arc, spray, and pulsed spray arc welding of Stainless Steel. It provides a higher welding speed, a broad weld with a flat crown and good color match, reduced porosity, and excellent alloy retention with good corrosion resistance.
11:38 PM Tom_L: Welding of carbon steel can be done with Carbon Dioxide alone and it produces the deepest penetration, the most smoke and the roughest weld. ...
11:38 PM Tom_L: Welding of stainless steel is typically done with C2 or 2% Carbon Dioxide and 98% Argon. ...
11:38 PM Tom_L: Welding of aluminum is typically done with Argon alone, with one exception.
11:39 PM Tom_L: http://gowelding.org/welding/mig-gmaw/gasses/
11:39 PM Tom_L: if you really care
11:40 PM rue_mohr: hahah
11:41 PM rue_mohr: the other green bottle I have is O2!!!
11:41 PM rue_mohr: didn't know that!
11:41 PM rue_mohr: I dont know if there is anything in it, casue I CANT GET TEH DAMN CAP OFF BY HAND
11:41 PM Tom_L: oxy is green
11:41 PM rue_mohr: and I'm in my pajamas
11:41 PM rue_mohr: I have a green argon bottle
11:41 PM rue_mohr: !?!?!
11:41 PM rue_mohr: oooh
11:41 PM rue_mohr: thread
11:41 PM rue_mohr: I bet the argon is righthand thread and the oxy is left?
11:41 PM rue_mohr: no
11:42 PM rue_mohr: fual is left
11:42 PM Tom_L: i doubt it
11:42 PM rue_mohr: hmmm
11:42 PM rue_mohr: I have a green argon bottle...
11:43 PM rue_mohr: http://www.siggases.com/images/products/gas-cyl-2-large.jpg
11:43 PM Tom_L: https://en.wikipedia.org/wiki/Bottled_gas#Colour_coding
11:43 PM rue_mohr: I dont know if its standardized
11:43 PM rue_mohr: well
11:44 PM Tom_L: i swear oxy is green here
11:44 PM rue_mohr: why does this green bottle say oxygen
11:44 PM rue_mohr: AND I ahve a green bottle thats argon
11:44 PM rue_mohr: !???!?!?!
11:44 PM Tom_L: by that chart that's correct
11:44 PM Tom_L: dark green
11:45 PM rue_mohr: and the shielding gas I'm using is a brown bottle
11:45 PM rue_mohr: with no label anymore
11:45 PM Tom_L: mine are brown iirc
11:46 PM Tom_L: later.
11:46 PM rue_mohr: gnight
11:53 PM rue_mohr: zhanx,
11:53 PM rue_mohr: if I blow match smoke into a jar of argon, it'll sit on top, but if its a jar of co2, it'll mix in.... ya think?
11:56 PM zhanx: should mix in
11:56 PM rue_mohr: I dont know whats in the tank tho
11:56 PM rue_mohr: I think its argon
11:56 PM rue_mohr: iirc argon is pretty heavy
11:57 PM zhanx: well its a noble gas, but I don't know how you would test for it
11:58 PM rue_mohr: weight against smoke?
11:58 PM zhanx: well if its co2 you can make sparkling water as a test
11:59 PM rue_mohr: ah,t eh water wont absorb argon
11:59 PM zhanx: correct
11:59 PM rue_mohr: I wonder how much rpessure that takes
11:59 PM zhanx: 10 psi and shake the bottle slowly
11:59 PM rue_mohr: !!! :)
11:59 PM zhanx: more like roll it side to side
