05:35 AM Tom_L: did that file eat you alive?
05:38 AM Tom_L: parts shipped yesterday btw
08:42 AM rue_: what was shipping?
01:40 PM Tom_L: A9 A10
06:30 PM rue_: hah I meant cost
06:30 PM Tom_L: gonna run an A8 part here in a bit
06:31 PM rue_: hu?
06:31 PM Tom_L: got some leftover 1/4"
06:31 PM rue_: 8...
06:31 PM Tom_L: figured i'd use it
06:31 PM Tom_L: should run another A9 so i have one
06:32 PM rue_: oh latch
06:32 PM Tom_L: i think A12 is ready to cut too
06:32 PM rue_: A9 is a complex shape
06:32 PM Tom_L: but i need to cut the 5/16 to length and i don't feel like it
06:32 PM Tom_L: A9 is
06:33 PM Tom_L: ballnose on the leg
06:33 PM * rue_ shivvers, hovers over the heater, and eats his icecream
06:34 PM Tom_L: it's quicker to use the mill to cut the stock but i have the surround on the table now
06:34 PM Tom_L: and i'd have to take the front off
06:34 PM rue_: I wonder if you can mount them via some kinda quick clip
06:35 PM Tom_L: sealed for leaks
06:35 PM Tom_L: maybe i'll cut a hunk while it's running
06:35 PM rue_: what if the surround were poly, held up with a wire frame?
06:36 PM Tom_L: it's still sealed around the base
06:36 PM rue_: yes, the poly could be sealed
06:36 PM Tom_L: i don't think it would leak out the front though
06:36 PM rue_: but fold-away if you need access
06:37 PM Tom_L: the drain works good
06:37 PM rue_: plastic film... poly? ""
06:37 PM rue_: good
06:37 PM Tom_L: 1/4" poly
06:37 PM rue_: no
06:37 PM rue_: 8 mil poly
06:38 PM rue_: plastic film, held up with a removable wire frame
06:38 PM rue_: but seal the poly to the bed
06:38 PM rue_: ?
06:38 PM Tom_L: i considered doing the same with the neoprene i have
06:38 PM rue_: but poly is clear-ish
06:39 PM rue_: the vapour barrier stuff
06:40 PM rue_: tom got quiet
06:40 PM rue_: I noticed
06:40 PM Tom_L: moving files around
06:40 PM rue_: just wait, he will say soemthing
06:40 PM rue_: see, told ya
06:40 PM Tom_L: gonna go out and fire things up
06:40 PM rue_: :)
06:40 PM Tom_L: you got quiet all night last night
06:41 PM Tom_L: did you print a softjaw?
06:41 PM rue_: I'm gonna try to remember what I want to do before I fall sleep
06:41 PM rue_: so I know when I wake up :/
06:41 PM rue_: not yet
06:41 PM Tom_L: there's one thing to do
06:41 PM rue_: I could do that, the printer will be available
06:41 PM rue_: ok, lets go to the shop where its warm
06:43 PM rue_shop3: hahahah, its 1mm across
06:44 PM rue_shop3: this is why you dont get spaceships made by aliens, they could come back REALLY small
06:46 PM rue_shop3: slicing...
06:46 PM rue_shop3: odd, tiny file
06:50 PM rue_shop3: printing
07:10 PM Tom_shop: what size holes are in A8?
07:15 PM Tom_shop: overall time: 8 min 3 sec
07:22 PM Tom_shop: A8 program proven...
07:30 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/rue/Can_Holder/Extra/A8_1.jpg
07:30 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/rue/Can_Holder/Extra/A8_2.jpg
07:32 PM rue_: :) that ones just a walk in the park eh?
07:32 PM Tom_L: heh
07:33 PM rue_: do you remember the cut time?
07:33 PM Tom_L: i posted it
07:33 PM Tom_L: 8 min 3 sec
07:33 PM rue_: oh geez
07:33 PM rue_: whats the DOC?
07:33 PM Tom_L: 1/2 the tool diameter
07:34 PM Tom_L: so . 0625
07:34 PM Tom_L: i probably could go deeper
07:34 PM rue_: I cant do more than 0.4mm without cooling
07:34 PM Tom_L: bump up the rpm and do a full cutter width deep
07:34 PM rue_: zippo:/files/programming/c/DAlib# units 0.4mm inch
07:34 PM rue_: * 0.015748031
07:35 PM Tom_L: iirc 6ipm here
07:35 PM Tom_L: 3k and 6 ipm
07:35 PM Tom_L: may start running em all at 4k and bump up the ipm to match the chip load
07:37 PM rue_: that was all the way up
07:37 PM rue_: I dont think my bits can take that
07:38 PM Tom_L: yours?
07:38 PM rue_: I peaked out at 100mm/min
07:38 PM Tom_L: how long does it take you to run one of those?
07:38 PM rue_: zippo:/files/programming/c/DAlib# units 100mm/min inch/min
07:38 PM rue_: * 3.9370079
07:38 PM rue_: well, right now I'm doing it at like 10mm/min, I'm gonna push that to about 85
07:38 PM rue_: cut time is like 13 hours
07:38 PM Tom_L: for that part?
07:38 PM Tom_L: holy crap
07:39 PM rue_: iirc
07:39 PM rue_: yea, I'm gonna use those tests I did on the weekend to up all the feed rates
07:39 PM rue_: but I dont have cooling
07:39 PM Tom_L: get some
07:39 PM rue_: :)
07:39 PM rue_: I just have a chip clearing blower
07:44 PM Tom_L: gonna go cut a hunk of 5/16 and run A12
07:44 PM Tom_L: 4 up
07:44 PM rue_: :)
07:44 PM rue_: that shoudl almost be finished printing
07:45 PM Tom_L: i need a vise to run the vise program
07:45 PM Tom_L: so i know how big to make the stock
07:50 PM rue_shop3: yes, its printed
07:50 PM rue_shop3: and my cellphone crashed
07:50 PM rue_shop3: gonna crash on the concrete some day
07:52 PM rue_shop3: Tom_L, I'll have to remake that stl, the poly count is too low and the latch dosnt fit in there
07:52 PM rue_shop3: ah!
07:52 PM rue_shop3: tho
07:52 PM rue_shop3: our cut is
07:53 PM rue_shop3: .15" over the top of the softjaw for the endcut
07:53 PM rue_shop3: hah, oh right, its thermoplastic, where is my heatgun...
07:56 PM rue_shop3: hmm
07:57 PM rue_shop3: the slot in the thin end of A12 should be abit deeper, by about 0.1"
08:00 PM rue_: images on way
08:03 PM rue_: http://ruemohr.org/~ircjunk/not_public_dont_open/tom/p1090737.jpg

08:04 PM rue_: http://ruemohr.org/~ircjunk/not_public_dont_open/tom/p1090742.jpg
08:04 PM rue_: I blame 41 on me, I must have put the line in the wrong place
08:16 PM Tom_shop: can't look out here
08:17 PM Tom_shop: interweb is too slow for some reason
08:23 PM Tom_shop: starting #4 A12 time so far: 12:55
08:24 PM rue_shop3: showoff
08:24 PM Tom_shop: hah
08:24 PM Tom_shop: they look nice
08:25 PM rue_shop3: if I got more than 0.2mm, the chips start catching in the cutter
08:25 PM rue_shop3: I went to 0.4mm and had to sit there with a spray bottle
08:26 PM Tom_shop: i could have run a whole plate full of these but i don't wanna be out here all night
08:26 PM rue_shop3: no poin
08:26 PM rue_shop3: t
08:26 PM Tom_shop: last pass #4
08:27 PM Tom_shop: for $5 i like this mister
08:27 PM rue_shop3: :)
08:28 PM Tom_shop: total runtime 4 parts: 16:50
08:29 PM Tom_shop: not too bad
08:30 PM rue_shop3: 4hrs ea is our time
08:30 PM rue_shop3: not with the new feed rates
08:34 PM Tom_shop: you're running 1/8" cutters?
08:35 PM rue_shop3: yup
08:48 PM Tom_shop: now you need a part tumbler to debur the edges
08:51 PM rue_shop3: hahah add another 16 hours to the job
08:51 PM rue_shop3: I have one
08:51 PM rue_shop3: what media should I use?
08:53 PM Tom_shop: pyramid media works pretty good on small parts
08:54 PM Tom_shop: i'm sure ebay has it
08:54 PM Tom_shop: there are different materials too and i'm not sure about that
08:54 PM Tom_shop: some are better for steel and some for aluminum
08:54 PM Tom_shop: or a mix of shapes
08:54 PM rue_shop3: ?
08:55 PM rue_shop3: I'v never actaully seen
08:55 PM rue_shop3: how about silicate sand?
08:55 PM rue_shop3: 30 grit?
08:56 PM Tom_shop: try it
09:01 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/rue/Can_Holder/Extra/A12.jpg
09:02 PM ASRock_pc: https://www.youtube.com/watch?v=LO2AvRVU0iE&feature=youtu.be
09:02 PM ASRock_pc: when loaded
09:03 PM rue_shop3: those curves look good
09:03 PM Tom_L: yeah that turned out nice
09:04 PM Tom_L: ~2 min on youtube
09:07 PM Tom_L: done
09:08 PM Tom_L: not sure what that material was but it cut nice
09:27 PM rue_: see th images?
09:28 PM rue_: of the softjaw?
09:28 PM rue_: geez thats a fast move
09:28 PM rue_: maybe it was youtube
09:29 PM rue_: nope
09:30 PM Tom_L: no but i can look now
09:32 PM Tom_L: what's wrong with that?
09:38 PM ASRock_pc: https://www.ebay.com/itm/2-8-SYNTHETIC-TUMBLER-TUMBLING-LIGHT-CUT-CUTTING-DEBURRING-MEDIA-SV-3-8-CONES/161313237806?hash=item258f04ab2e:g:vaAAAOSw0vBUdNFY
09:38 PM ASRock_pc: we used that cone stuff and some trianguar that was skewed from top to bottom
09:40 PM ASRock_pc: https://www.ebay.com/itm/5-lbs-Medium-Ceramic-Abrasive-Polishing-Tumbler-Media-Garage-Shop-House-New/253377133318?hash=item3afe743b06:g:MDQAAOSw9p9aYOTQ
09:40 PM ASRock_pc: similar
09:41 PM rue_: I had to take a heat gun to it to make the part fit
09:41 PM rue_: but the positions were a little out, I blame me
09:41 PM Tom_L: the odd shapes get into all the crevices
09:41 PM Tom_L: ?
09:41 PM Tom_L: do i need to change it any?
09:41 PM rue_: can you see how its out from the images?
09:41 PM Tom_L: did you cut those parts with it?
09:41 PM rue_: no
09:41 PM Tom_L: the part needs to be higher?
09:41 PM rue_: all I have are finished parts
09:42 PM rue_: lower
09:42 PM Tom_L: i have parts to run :)
09:42 PM Tom_L: the left one lower?
09:42 PM Tom_L: what about the right one?
09:42 PM rue_: your cuts are suppsoed to be flush with the top of that softjaw, yes?
09:42 PM Tom_L: yes
09:42 PM Tom_L: that's what you gave me
09:42 PM rue_: the right one needs to be tipped up a little on the thin end
09:42 PM rue_: I know
09:42 PM Tom_L: i put them right on the line
09:42 PM rue_: I had to guess
09:42 PM rue_: its my fault, I was pretty close for a guess tho
09:43 PM Tom_L: yeah
09:43 PM Tom_L: degree wise gimme a tip number
09:44 PM Tom_L: gotta boot up in 64bit
09:46 PM rue_: its 0.1" high on the tip
09:46 PM rue_: the left one is high my 0.2"
09:46 PM Tom_L: bring the left one down .2"?
09:46 PM rue_: right
09:46 PM rue_: er, correct
09:46 PM Tom_L: or up
09:46 PM Tom_L: it would cut deeper if it went up
09:46 PM rue_: left down 0.2", tip of right up 0.1"
09:46 PM Tom_L: think backwards on opposite parts
09:47 PM Tom_L: you want a deeper cut on the left one?
09:47 PM rue_: http://ruemohr.org/~ircjunk/not_public_dont_open/tom/p1090742.jpg
09:47 PM rue_: see how its over the line?
09:47 PM Tom_L: i'm looking at that one already
09:47 PM Tom_L: the left one sits too high
09:48 PM Tom_L: i will lower the pocket
09:48 PM rue_: yea, thats the proper cut
09:48 PM Tom_L: by .2?
09:48 PM rue_: so the left part needs to go down into the softjaw by 0.2"
09:49 PM rue_: know what i mean?
09:49 PM Tom_L: yeah i'm working on it
09:49 PM rue_: ok
09:49 PM rue_: you can see that the tip of the right one sits too low int eh softjaw too
09:57 PM Tom_L: how many degrees would you say?
09:57 PM Tom_L: i went 7 deg
09:57 PM rue_: tip up 0.1inch, its about 1" long...
09:58 PM rue_: hmm, I can work this out, I think
09:58 PM Tom_L: i'll send you a file to try
09:58 PM rue_: opposite adjacent
09:58 PM rue_: sohcahtoa
09:58 PM rue_: tan
09:58 PM rue_: arctan of (0.1/1.3)
09:58 PM rue_: hmm, where is my math thing
09:59 PM * Tom_L held his thumb up and eyeballed it
09:59 PM rue_: hmm will google do that
10:00 PM rue_: 4.4 degrees
10:00 PM rue_: yes, google will do that
10:00 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/rue/Can_Holder/Extra/
10:00 PM Tom_L: i went 7 degrees
10:00 PM Tom_L: 5 didn't look enough
10:00 PM Tom_L: 10 looked too much
10:00 PM Tom_L: try that file
10:00 PM Tom_L: a12_visejaw_adjusted.stl
10:01 PM rue_: heh, I shut down the shop for the night...
10:01 PM Tom_L: oh poop go check the file
10:02 PM rue_: I'll get it set up for tommorow
10:02 PM Tom_L: can you view it?
10:02 PM rue_: yes
10:02 PM rue_: I fixed that
10:02 PM Tom_L: well see if it looks better
10:03 PM Tom_L: those parts are so small it's hard to tell in cad
10:03 PM rue_: looks plausable
10:03 PM Tom_L: well the one is .2" deeper
10:03 PM Tom_L: and the other is 7deg skewed
10:04 PM rue_: yup, I'll print tommorow and test it out
10:04 PM Tom_L: from the point the 2 lines intersected you gave me
10:04 PM rue_: :) yea I know, I missed
10:04 PM Tom_L: i'm just saying that's the centerpoint of the rotation
10:05 PM rue_: sooo what did shipping cost?
10:05 PM rue_: I'm burning to know if we can have ya make things for us
10:06 PM rue_: I wonder what the shipping time will be too
10:06 PM rue_: it went out yesterday?
10:09 PM Tom_L: something like that when i was making programmers would have been about $3
10:09 PM Tom_L: these were 10
10:09 PM Tom_L: 4 A10 and 3 A9 i think
10:09 PM rue_: k
10:09 PM Tom_L: part count
10:10 PM rue_: I dont have our numbers togethor, so I dont know how much it costs us
10:10 PM Tom_L: but i don't know if that's a flat fee up to a certain weight or not anymore
10:10 PM rue_: usually is
10:10 PM rue_: iirc a 'small packet' was rediculusly large
10:10 PM Tom_L: i can put quite a few parts in those padded shipper envelopes
10:10 PM rue_: oh the spagetti...
10:11 PM Tom_L: i could do some of the harder or more time consuming ones
10:11 PM Tom_L: or help improve your methods like this A12 thing
10:13 PM Tom_L: once the programs are proven i can do a setup fairly quick
10:13 PM rue_: what I learned on the weekend will speed things up a lot
10:13 PM Tom_L: and do quite a few on a slab
10:13 PM rue_: were kinda idle right now, no orders
10:13 PM Tom_L: how many do you expect to sell in 6 mo?
10:14 PM rue_: hmm
10:14 PM Tom_L: i got lots of blue boxes left btw :)
10:14 PM Tom_L: if you need a project box
10:14 PM rue_: 30?
10:14 PM rue_: we still have to know if your design is gonna work tho
10:14 PM Tom_L: i know
10:14 PM Tom_L: the A9 you mean?
10:14 PM rue_: I have to redesign the other bit
10:14 PM rue_: yup
10:15 PM Tom_L: the rest is the same i think right?
10:15 PM rue_: yup
10:15 PM Tom_L: i detached A10 so it might be slightly different
10:15 PM Tom_L: unless you send me an A10 by itself
10:15 PM Tom_L: and any other parts you may want
10:15 PM rue_: A7 needs a redo for yours
10:15 PM Tom_L: i will spot the holes and let you drill them
10:16 PM Tom_L: i'm not clear on all the hole sizes
10:16 PM Tom_L: A7 is plastic right?
10:16 PM rue_: so, the spring pins dont look like they will work, a bit large, but we found dowel pins were gonna try
10:17 PM rue_: A2, A7, A3 are printed plastic
10:17 PM Tom_L: oh yeah, you're gonna start using dowen pins right?
10:17 PM Tom_L: you need help with A7 design?
10:17 PM rue_: maybe, we ordered like 5, gonna try em
10:17 PM rue_: na, I can do that up
10:17 PM Tom_L: i can draw stuff fairly quick with the right data
10:17 PM rue_: I think its in solidworks tho
10:17 PM Tom_L: i can use sw
10:18 PM Tom_L: that's a 100% translate to catia
10:18 PM Tom_L: usually
10:18 PM rue_: iirc, all those printed parts have solidworks files
10:18 PM Tom_L: or i could do it in sw
10:18 PM Tom_L: i've got probably 4-6 cad packages i can use
10:19 PM rue_: :)
10:19 PM Tom_L: depending on the needs
10:19 PM rue_: heh, just dont hand ya a metric dxf :)
10:19 PM Tom_L: well i can scale it now
10:19 PM Tom_L: i just forgot
10:19 PM rue_: :)
10:19 PM Tom_L: never had to do much of that
10:20 PM rue_: everything here is like that cause of the way I design stuff
10:20 PM Tom_L: A2 would be trick polished aluminum
10:20 PM rue_: so it was kinda funny
10:20 PM rue_: the surface of A2 would be trickey
10:21 PM Tom_L: why?
10:21 PM rue_: he tried to finish a few of those ones I cut ont eh wekend
10:21 PM rue_: said sanding them is really hard cause they are small and heat up fast
10:21 PM Tom_L: vibra tumbler fixes that
10:21 PM Tom_L: but they would be dull
10:21 PM rue_: you have to really round off the finger edge of them
10:22 PM Tom_L: i can get a radius cutter if deemed necessary
10:22 PM Tom_L: it would be hard to do on the trigger though
10:22 PM rue_: were only making the aluminum ones as a special order or backup, printing them is really easy at this point
10:22 PM Tom_L: i gotta get a good vise
10:22 PM Tom_L: gimme that file and i'll program it
10:23 PM Tom_L: what thicness is it?
10:23 PM rue_: 1/4
10:23 PM Tom_L: the holes are just for looks?
10:24 PM Tom_L: well, one holds the trigger
10:24 PM rue_: copies of the origional, we think its from the jigs he used, locator pins
10:24 PM rue_: but they use the holes in the handle for carrying them
10:24 PM Tom_L: for marking trees?
10:24 PM rue_: logs
10:25 PM rue_: well, I'm confused
10:25 PM Tom_L: send me that one so i have something to work on tomorrow
10:25 PM rue_: I think the files are on the windows laptop in the shop
10:26 PM Tom_L: i'll wait on making my A12 plate until you print and say that mod is ok
10:27 PM rue_: rounding.fcstd
10:27 PM rue_: is that a file extension you recognize?
10:27 PM Tom_L: not at all
10:28 PM rue_: huh, dont think the files are here
10:29 PM rue_: sorry, I'll have to try to find the files on the laptop tommorow
10:29 PM rue_: wont be easy, we didn't organize the files
10:30 PM Tom_L: get organized!
10:30 PM Tom_itx: https://www.ebay.com/itm/125-1-8-RADIUS-HIGH-SPEED-STEEL-CORNER-ROUNDING-END-MILL-3-8-SHANK/302012434074?hash=item465158069a:g:VJ8AAOSw7s5XhTZq
10:32 PM Tom_L: that or a chamfer instead
10:37 PM rue_: I should have those files on the server in case the laptop bails anyhow
10:38 PM rue_: I hope my buddy who designed them is ok, he has been having strokes, cant use his right hand
10:39 PM Tom_L: not good
