02:47 PM spline: https://tucows.com/retired/
07:51 PM spline: Tom_L, got a photo of it made and done?
08:03 PM Tom_L: spline, you can see it working in some of these: https://www.youtube.com/channel/UCoG_JaILNz3Q-jBZ5MiK1dA
08:04 PM spline: oh damn nice - what kinda spindle?
08:04 PM Tom_L: i started with a sheline mill and the spindle is the only thing left sherline
08:05 PM Tom_L: just recently added the new spindle motor
08:06 PM spline: gotcha we had one of those at the space someone got linuxcnc running w/and put limits on
08:07 PM spline: it could do like ten thou passes on like 3, 4, maybe 5 series aluminum
08:07 PM spline: looks like a hp or so?
08:07 PM Tom_L: 1.2kw
08:08 PM Tom_L: it can cut steel
08:08 PM Tom_L: slow but it does ok
08:09 PM aandrew: my daughter's 17th bday is coming up. she wants an ice cream cake with the red hot chilli peppers pic on it
08:09 PM aandrew: so I asked her for a pic or I'm putting justin bieber on it
08:09 PM aandrew: she sent me a pic so I sent back justin bieber saying "ok got it"
08:09 PM spline: 1.5 about
08:09 PM spline: yeah
08:09 PM aandrew: she sent the pic again so I sent back the same JB pic with "yep I got it"
08:09 PM spline: most knees are like 1.5 or so
08:09 PM spline: I can do like 10-20 thou passes on regular carbon steel
08:09 PM spline: anything harder/stainless, half
08:09 PM aandrew: she sent the RHCP pic again and I sent back JB and said "I got your pic, you don't have to keep sending it"
08:10 PM spline: get a Al-TiN coated bit, upflute
08:10 PM aandrew: I'm waiting for the DAAAAAAAAAAAAAAAAAAAAAD
08:10 PM spline: 3 flute
08:10 PM spline: I have a few 3/16 (.1875")
08:10 PM spline: if you want to be jealous, this was when we got our 2nd table: https://photos.app.goo.gl/NTKgJoXfRqUjDVKNA
08:10 PM spline: we were basically testing our new ZrN coated Amana bits on aluminum
08:11 PM spline: that's 1/8th inch (about 3mm) 5052-H6 temper, full depth single pass 160ipm
08:11 PM spline: reason why we call it ludacris speed :)
08:11 PM spline: and it was an absolutely pristine edge quality.. you can hear it on the endmill just humming
08:12 PM spline: we normally would run about 55ipm half that (1/16th passes) uncoated, maybe 80 or faster. single flute, oflute, upcut, 1/4" diam carbides
08:12 PM Tom_L: is that 30 or 40 taper spindle?
08:12 PM spline: iso32
08:12 PM spline: all our toolholders
08:12 PM spline: HSD makes the spindle - 24k rpm max, 10hp
08:12 PM Tom_L: i used to work / program the big ones too
08:12 PM Tom_L: it's just a hobby now
08:13 PM spline: er lemme find it out. They're R32 collets
08:13 PM Tom_L: close enough
08:13 PM spline: yeah, ill be that way at some point. Those machines are fun
08:13 PM spline: I obviously could plow through steel if we had flood coolant
08:13 PM Tom_L: the whole thing was built with scrap
08:13 PM spline: its just got misters and we use WD40. Have a coldair gun too if we are doing big plastics work
08:13 PM spline: yeah, which is awesome
08:13 PM Tom_L: a few things new like ballscrews etc
08:13 PM Tom_L: mesa electronics
08:14 PM spline: I forget the hp on the vacuum pump - it takes 208v/3ph and is on a 30A circuit
08:14 PM spline: it pulls 25A per leg (I've seen 200A on the start)
08:14 PM spline: per leg
08:14 PM spline: what kinda motors?
08:14 PM Tom_L: steppers
08:14 PM spline: that gantry on there weighs 750lbs before the spindle/carriage (100hp)
08:14 PM spline: so its got 2xnema 34 servos on the Y
08:15 PM spline: think its a 23 on the Z but the X is a 34 servo. 7xatc (my god is this so handy)
08:15 PM spline: I learned to machine on a manual bridgeport of course
08:15 PM Tom_L: 570 in/oz nema 23
08:15 PM spline: we had a bunk 1hp crappy lathe (great to learn plastic/wood on and barely touch aluminum) but we had a 6hp 19x40 donated to us (yeah lucky us)
08:16 PM spline: you do aluminum mainly on it?
08:16 PM Tom_L: yeah since it's readily available here
08:16 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Brass_cup/Brass_Cups2.jpg
08:16 PM Tom_L: did those from solid brass just because
08:17 PM spline: 632?
08:17 PM Tom_L: i dunno
08:17 PM spline: did my first brass turning using that I think - free machining
08:17 PM Tom_L: that was milled
08:17 PM spline: doesn't gum up/as hard as like muntz
08:17 PM spline: forgetting my alloys though
08:17 PM spline: nice mitutoyo calipers :)
08:17 PM spline: love their proucts but $
08:18 PM spline: how'd you thread the cap?
08:18 PM Tom_L: did the box for em as well
08:18 PM Tom_L: threadmill
08:18 PM spline: I can see the tooling marks http://tom-itx.no-ip.biz:81/~webpage/cnc/Brass_cup/Brass_Cup_base2.jpg
08:18 PM spline: wow how big is that?
08:18 PM spline: we just got threading in Aspire 10.5 (our CAM software but can also do basic CAD)
08:19 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/thread_mills/Thread_mill2.jpg
08:19 PM spline: and we've done a bit of threading using those routers
08:19 PM Tom_L: single point threadmills
08:19 PM spline: AXYZ had a way t do threading but you required to manually program each hole on the console and used an eccentric collet
08:19 PM spline: yeah that's what we use
08:19 PM spline: yep ours are the single point
08:20 PM Tom_L: it was a custom thread mostly to test my thread macro
08:20 PM spline: so that was done in cnc
08:20 PM Tom_L: ~1.5" D
08:20 PM spline: on the mill
08:20 PM Tom_L: yes
08:20 PM spline: damn, nice
08:20 PM spline: I remember learning powerfeed on the lathe and man its beautiful
08:20 PM spline: sometimes annoying learning what knob for what
08:21 PM Tom_L: https://www.youtube.com/watch?v=Jmmw4qLhLMk
08:22 PM Tom_L: that was before i got the new spindle motor
08:22 PM spline: did a conventional there on the inside?
08:22 PM spline: sounds good though I didn't hear chatter
08:23 PM spline: but it was in the jaws -- just lack of material
08:24 PM spline: probably the closest thing I've done to that is a piece out of some scrap 3/4" aluminum called "Kagome" -- it's a lattice
08:24 PM spline: https://photos.app.goo.gl/xMjKJ5Grd7MRSr8YA
08:24 PM Tom_L: i run it slower than i need to
08:24 PM spline: I had to pocket out the insides then make a jig to hold the thing in to do some cleaning up
08:24 PM Tom_L: this your mill or a makerspace?
08:24 PM spline: one of the routers at work
08:25 PM spline: we only had a Tormach P1100 at our makerspace but also a 6'x12' burn table with a 45amp hypertherm
08:25 PM Tom_L: i'm gonna go assplant a while
08:26 PM spline: oddly enough, I did a similar piece that I gave away - this is it getting plasma'd (0.25" aluminum) https://photos.app.goo.gl/8PGyNxhdTsiTaf576
08:27 PM spline: and if you want some real fun: I got to design and be part of the process making my wife's engagement ring out of Titanium. It's a tension setting with a 6mm synthetic Alexandrite stone: https://photos.app.goo.gl/NnVf8zX4ycTwgcm67
08:28 PM spline: so Grade5 titanium - we first cnc'd the blank so it'd go into the VMC and turn more into a lobe. Then the Lobe was thrown into Bruce's hacked Tormach P1100 but with a 15kW fiber laser
08:29 PM spline: yeah... my god was that insanely cool. You can see the white sparks from when its blasting through 6mm of titanium (3.6ipm) https://photos.app.goo.gl/d1CU3bYKqXMBMR7F7
08:29 PM spline: bit of cleanup then we used a screwdriver with tape to basically "open it up" and drop the stone in - one of the coolest experiences I've ever had
08:29 PM spline: bruce also had a laser welder .. pumps atmosphere out, o2 in. can do tiny little pulses and weld together 1mm of material easily. dials in the heat so precisely
08:30 PM spline: sadly, no fiber laser or waterjet for us.. we mainly route (have an 80W co2 laser too) but I have local job shops I throw cash to when I need crazy stuff done
08:34 PM rue_mohr: hi
08:35 PM rue_mohr: ok it goes up a lot, can I get a summary?
08:35 PM rue_mohr: DAMNIT i HAVE TO FEED THE CAT
08:38 PM spline: haha sorry - talking projects and machining
08:38 PM spline: I try to video/photo anything neat/cool I machine/make
08:41 PM spline: another: our former lead fabricator (good friend of mine) him and I doing some Silicon Bronzing TIG on the "Hypercube" laser cut tube steel (looks like stainless but its regular) https://photos.app.goo.gl/zPvh9Vx6ctyLwPgK8
08:42 PM spline: really cool kit you can buy from this company that makes stuff like that to advertise having a 5kW fiber laser tube cutter
09:08 PM rue_mohr: ok
09:18 PM rue_shop1: filter at 3.5k ohms with .0047uF
09:58 PM aandrew: rue_shop why don't your cats feed themselves?
10:07 PM rue_mohr: meh
11:36 PM rue_mohr: darkrose, house?
11:54 PM rue_mohr: damn, I have to start getting myself converted
11:54 PM rue_mohr: I cant wait for the tools or the knowledge
11:54 PM rue_mohr: its gonna be a wickid run to the line
11:55 PM darkrose: nope
11:55 PM rue_mohr: shouldn't be like, this, I should have time to be sure footed
11:55 PM rue_mohr: it'll be like trying to jump thru spinning blades
11:55 PM rue_mohr: hold your breath and just hope you live
11:56 PM rue_mohr: just damn
11:57 PM rue_mohr: I wish there were a peer
11:59 PM rue_mohr: I really need to change directions
