01:54 AM rue_mohr: sometimes I wish I knew where my mind were going with all this
04:49 AM Tom_L: morning
04:49 AM Tom_L: i had a .250 reamer and he gave me a .253
04:51 AM Tom_L: used the .250 on the bottom and the .253 for the top that slides
09:10 AM rue_mohr: nice

05:26 PM Tom_L: i think if i remade the top piece without the step i screwed up on the sides would be nice and smooth but it's alot better than it was
06:30 PM Tom_L: ok, mine is too wide :/
06:33 PM Tom_L: probably at least .050"
06:34 PM Tom_L: but i can pobably fix it
06:34 PM Tom_L: just shave probably .030 off each side and remake the top which needed redone anyway
06:36 PM Tom_L: when you get in, measure the width of yours...
07:10 PM rue_mohr: hi
07:11 PM rue_mohr: sure
07:11 PM Tom_L: starting to make a new top piece but waiting for the width
07:12 PM rue_mohr: ok ok hopld on
07:14 PM Tom_L: did you see the mods/additions?
07:14 PM Tom_L: that pin works good to release it
07:16 PM Tom_L: catch you in the shop..
07:19 PM rue_shop3: "15mm" 14.84mm
07:20 PM Tom_shop: yeah mine is 17mm so that's a problem
07:20 PM Tom_shop: so i'll shave some off each side and salvage the bottom
07:21 PM Tom_shop: thanks
07:22 PM Tom_shop: i'll shoot for the 14.84
07:23 PM Tom_shop: .584"
07:23 PM rue_mohr: its not 15 cause I cut the piece wrong
07:23 PM rue_mohr: the print is 15mm, and the bend should match
07:24 PM Tom_shop: well should it be 15 then?
07:24 PM Tom_shop: it doesn't seem to spring back much like i thought it would
07:25 PM rue_mohr: na
07:25 PM rue_mohr: I'm dead tired
07:25 PM Tom_shop: 14.84?
07:26 PM Tom_shop: i'll split the difference :)
07:26 PM Tom_shop: unless i'm told otherwise
07:28 PM rue_shop3: it shoudl be 15mm
07:28 PM rue_shop3: how wide is the printed handle?
07:28 PM rue_shop3: it should be 15...
07:28 PM Tom_shop: i dunno, i'll check before i start cutting much
07:28 PM Tom_shop: 15 it is then
07:38 PM rue_shop3: observation, curiosity, investigation, education
07:38 PM rue_shop3: hmm
07:39 PM Tom_shop: huuu?
07:42 PM rue_shop3: thoughts settling out of the results of the day
07:43 PM Tom_shop: utter madness!!
07:43 PM Tom_shop: i'm currently in a therapy session :)
09:07 PM rue_mohr: whoa gonna fall asleep in my chair again
10:40 PM Tom_L: ok i think i got it reworked
10:40 PM Tom_L: 15mm wide and will acomodate .125 material
10:41 PM Tom_L: i'll have to find some scrap or anneal that last part
10:41 PM Tom_L: i could just test it on some scrap
10:48 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/rue/Can_Holder/A9_New/MODS/fixture/A9_Fixture24.jpg
10:52 PM rue_mohr: :)
10:53 PM rue_mohr: no fair, you got all the industry experience I never got with my diploma of technology in robotics and automation :)
10:56 PM Tom_L: i didn't either
10:57 PM Tom_L: that radius on the edge makes all the difference
11:09 PM Tom_L: so i tried rebending one which wasn't the best idea
11:10 PM Tom_L: it bent but i think it would have done better if it had been the first time
11:10 PM Tom_L: it got a little more narrow but it was tight getting it apart
11:14 PM rue_mohr: they dont rebend
11:14 PM rue_mohr: :)
11:14 PM rue_mohr: which creates a horrible feeling in your gut if you realize you just bent one the wrong way
11:15 PM Tom_L: hah
11:16 PM Tom_L: i had to think about which way they bent when i did the first one
11:16 PM rue_mohr: I actually stamped into it "pocket up" and I still got one wrong
11:16 PM rue_mohr: watchig the annealed tabs too close
11:18 PM Tom_L: i may drill the holes on the top part out a bit. for some reason they're a little tighter than the first one
11:18 PM Tom_L: i'm sure i measured it right...
11:18 PM Tom_L: the first one slid on the pegs like butter
11:19 PM Tom_L: it wouldn't matter if they were a little bit loose
11:19 PM Tom_L: the sides will align when it clamps down
11:19 PM rue_mohr: did you give it a little oil?
11:19 PM Tom_L: yeah
11:19 PM Tom_L: i'm not sure what happened
11:20 PM Tom_L: i had to recalculate things because the block was a tiny bit bigger but that side dimension was the same
11:20 PM Tom_L: i had to refigure the slot
11:20 PM rue_mohr: I have a few small hydraulic rams
11:20 PM rue_mohr: I wonder if two formers into each corner
11:20 PM rue_mohr: ...
11:20 PM Tom_L: it still works fine in the vise
11:20 PM rue_mohr: yes
11:21 PM rue_mohr: do you think the force is beyond an arbour press?
11:21 PM Tom_L: not at all
11:21 PM rue_mohr: I asked the local cnc guy for a price on 15mm pins,
11:21 PM Tom_L: the 3" handle on my machine vise worked
11:21 PM rue_mohr: said probably $5ea @ 100pcs
11:21 PM rue_mohr: sigh
11:21 PM Tom_L: ouch
11:21 PM rue_mohr: well, for our consumption
11:22 PM rue_mohr: he has a feeding chuck cnc lathe tho
11:22 PM rue_mohr: it would be more setup than work
11:22 PM Tom_L: oh i misread that, yeah to have them made would cost too much
11:23 PM rue_mohr: something is loose in my lathe
11:23 PM Tom_L: besides, you need something to do
11:23 PM Tom_L: :)
11:23 PM rue_mohr: I'm noticing that its too squishy
11:23 PM Tom_L: do you ever lube it?
11:23 PM rue_mohr: cant tell yet if the chuck is moving or the apron
11:23 PM rue_mohr: yea, its quite well lubed
11:24 PM rue_mohr: saw some of the stuff he was making, looked good
11:24 PM Tom_L: what all does he make?
11:24 PM Tom_L: just lathe or both lathe and mill?
11:24 PM rue_mohr: hmm 3 machines iirc
11:24 PM rue_mohr: and he got a 3d printer recently
11:25 PM rue_mohr: pretty big one
11:25 PM Tom_L: not alot of call for lathe parts usually
11:25 PM rue_mohr: washers with a special face profile
11:25 PM rue_mohr: some kinda plastic
11:27 PM rue_mohr: if only I could happen upon a hydraulic chuck
11:27 PM Tom_L: it's been so long i've forgotten how to run one
11:27 PM Tom_L: i ran/programmed my bud's Okuma lathe
11:28 PM Tom_L: it had the chuck but no tail tube
11:28 PM Tom_L: at least i don't remember one
11:29 PM rue_mohr: hmm, cut a piece to work on off the tail stock...
11:29 PM Tom_L: the vo tech has a big printer probably 2-3' square print area
11:29 PM rue_mohr: his looked a good 12x18"
11:29 PM rue_mohr: which is pretty big
11:29 PM rue_mohr: maybe a bit more
11:30 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/threading/prints/plastic_prints.jpg
11:30 PM Tom_L: that manifold was done on it
11:31 PM rue_mohr: :)
11:31 PM rue_mohr: is that for my S10?
11:31 PM Tom_L: all sorts of different plastics there
11:31 PM Tom_L: doubtful
11:31 PM Tom_L: says sweeden on it
11:32 PM Tom_L: that grey vase is 1 layer thick
11:32 PM rue_mohr: "vase mode"
11:32 PM rue_mohr: you have to have the right shaped project
11:32 PM Tom_L: i'm sure
11:39 PM Tom_L: i should probably go to sleep
