09:28 AM rue_mohr: http://ruemohr.org/~ircjunk/tempimage/p1130047.jpg gonna try casting myself a structural pipe clamp
08:57 PM rue_mohr: http://ruemohr.org/~ircjunk/projects/cnc6/p1130050.jpg
08:57 PM rue_mohr: am I crazy?
08:57 PM rue_mohr: 6 of these cast in aluminum?
09:00 PM Tom_L: just a little
09:01 PM rue_mohr: or should I just weld it
09:01 PM Tom_L: make a square plate sandwiched between and X weld
09:01 PM rue_mohr: not sure on how to weld that, it'd involve some [ or angle in between
09:01 PM rue_mohr: o
09:01 PM rue_mohr: --
09:01 PM rue_mohr: its hard to get in there
09:02 PM Tom_L: you don't have to get in the pipe to weld it
09:02 PM rue_mohr: and, I have higher odds of it being crookid if I weld it
09:02 PM Tom_L: in fact it would be a bad idea
09:02 PM rue_mohr: no in the corner of the -> _O
09:02 PM Tom_L: i had odds against me on welding the mill too but it turned out fine
09:03 PM Tom_L: plastic isn't strong enough for the application?
09:04 PM rue_mohr: hah, no the idea is to cast it with alllll the aluminum I have
09:04 PM rue_mohr: as the stockpile is getting stupid
09:04 PM Tom_L: oh
09:04 PM Tom_L: i thought it may create a shortage
09:04 PM rue_mohr: no, it might only take a dent out of the pile I have
09:04 PM Tom_L: you'd better get some proper casting sand
09:05 PM Tom_L: and no i'm not gonna mill a mold for that
09:05 PM Tom_L: :)
09:05 PM rue_mohr: hah
09:05 PM rue_mohr: I can do an ipression plate for sand casting it
09:05 PM Tom_L: your sand didn't seem to come out all that well yet
09:06 PM rue_mohr: more learning
09:06 PM rue_mohr: its course too, so fine stuff doesn't work out well
09:06 PM Tom_L: what does plaster do?
09:07 PM rue_mohr: oh its horrid, the sulfur
09:07 PM Tom_L: k
09:07 PM Tom_L: what's the part for?
09:08 PM rue_mohr: the frame consists of 3 uprights and 2 rails
09:08 PM rue_mohr: then the actaul cnc rails space off there
09:08 PM Tom_L: so its for the big cnc
09:09 PM rue_mohr: yep
09:11 PM rue_mohr: this project will quickly become unrelocatable
09:12 PM rue_mohr: trying to work out a location for it
09:12 PM * Tom_L looks behind rue_mohr's shop
09:14 PM rue_mohr: its inclined the idea was to put it under the house eave
09:14 PM rue_mohr: not completely sold on that right now
09:35 PM rue_mohr: http://ruemohr.org/~ircjunk/projects/cnc6/p1130051.jpg
09:35 PM rue_mohr: thats the bed layout, it would be upright on edge (at an angle)
09:36 PM rue_mohr: 6' x 9',
09:36 PM rue_mohr: but the footprint will be more like 3'x9'
09:36 PM rue_mohr: and that mock is upside down too
09:43 PM Tom_L: you may want at least one triangle brace
09:43 PM rue_mohr: oh yea, I got lots of junk for that
09:44 PM Tom_L: moved all but 3 pieces into closets & bathroom for the carpet guys tonight
09:44 PM Tom_L: i'll work on those tomorrow probably
09:44 PM rue_mohr: gave up on the carpet eh?
09:44 PM Tom_L: she did
09:44 PM Tom_L: it was gettin pretty old
09:45 PM Tom_L: i ripped that and the baseboards out the other day
09:45 PM Tom_L: so the walls would dry better
09:46 PM rue_mohr: I think its common to tear off the bottom 6" of drywall
09:46 PM Tom_L: they came a day later and drilled holes in the sheetrock so it would air out
09:46 PM Tom_L: it's all dry now
09:46 PM Tom_L: they'll get their junk out tomorrow morning
09:46 PM Tom_L: they allowed for 24" but i'm not gonna cut it
09:46 PM Tom_L: they were just covering their ass
09:47 PM Tom_L: the insurance co that is
09:47 PM rue_mohr: huh
09:47 PM Tom_L: their meters showed no indicaton of wet
09:47 PM Tom_L: and the air was 26% humidity
09:47 PM Tom_L: from 78 or such
09:49 PM rue_mohr: even space to build this thing is.... hmmm
09:49 PM rue_mohr: I wonder if I should tear down the pipe bender
09:49 PM rue_mohr: I could put this in that tent
09:49 PM Tom_L: it was tight for me building the mill
09:50 PM rue_mohr: http://ruemohr.org/~ircjunk/tempimage/p1130052.jpg
09:50 PM rue_mohr: that is the progress on the small cnc
09:50 PM rue_mohr: (not the motor, the bit under it)
09:50 PM rue_mohr: :)
09:50 PM Tom_L: spindle motor ?
09:50 PM Tom_L: :)
09:50 PM rue_mohr: hah, no
09:51 PM rue_mohr: its the motor off a compressor I got
09:51 PM Tom_L: nice industrial motor
09:51 PM rue_mohr: 1.5Hp 220V, inconvienient, so, I changed it out for a 120V 1Hp
09:51 PM Tom_L: not fully enclosed though is it?
09:51 PM rue_mohr: which,.... might also be a challange to feed
09:52 PM Tom_L: mine is 5hp 220v
09:52 PM rue_mohr: iirc, all the wiring in the shop, with exception of the lighting circuits, is #12 wire
09:52 PM Tom_L: should be ok for that no?
09:53 PM rue_mohr: if I upgrade something to 20A
09:53 PM Tom_L: iirc that's code here for 15A
09:53 PM rue_mohr: code for 20
09:53 PM rue_mohr: 30 fixed heating load iirc
09:53 PM Tom_L: maybe
09:53 PM Tom_L: we're allowed to run 14 to overhead lights
09:54 PM rue_mohr: 14 is everything normal here
09:54 PM Tom_L: but not outlets
09:55 PM rue_mohr: I did 12 cause I wanted to be able to upgrade circuits int eh shop
09:55 PM Tom_L: iirc 10 goes to the range
09:55 PM rue_mohr: dont know if I did the welder plug in #10
09:55 PM rue_mohr: its on a 20A right now
09:55 PM Tom_L: and probably the welder in the garage
09:56 PM Tom_L: and compressor
09:56 PM Tom_L: i forget what it was
09:56 PM rue_mohr: I need to test the tank
09:56 PM rue_mohr: 1979
09:56 PM rue_mohr: I realized I have a hydraulic hand pump
09:56 PM rue_mohr: so, if I fill 'er with water and use oil for the pressure cycle
09:56 PM rue_mohr: 450psi
09:56 PM Tom_L: i gave one of those away
09:57 PM Tom_L: is pressure from a liquid the same as gas?
09:58 PM Tom_L: air
09:58 PM rue_mohr: hydro is done with water cause if the tank ruptures, it doesn't explode
09:59 PM Tom_L: where's the fun in that?
09:59 PM Tom_L: i might disect the water heater tomorrow
10:23 PM rue_mohr: welding seam
10:23 PM rue_mohr: I bet the origional bead *mostly* missed
10:23 PM rue_mohr: and the wonder is how it held togethor so long in the first place
10:23 PM rue_mohr: look for the big circled OK on the steel tank
10:24 PM rue_mohr: in oil crayon
10:25 PM rue_mohr: robot welders and people not paid enough for doing their hydro checks I think
10:28 PM rue_mohr: so its funny eh?
10:29 PM rue_mohr: the only reason we missed the arduino thing is cause we didn't write io libraries to make them easy to program
10:29 PM rue_mohr: (looking at the avr boards)
10:29 PM rue_mohr: just a bootloader and an io library away
10:30 PM rue_mohr: I'm going to cast one of those, and then I'll decide what to do
