11:33 SquirrelCZECH hmm
11:33 SquirrelCZECH Kalman filter he said
11:33 uirrelCZECH once learned from nice tutorial abou
11:33 SquirrelCZECH but now I can't find anything nice
15:15 GuShH rue_more: ideas on lifting the mill column?
15:15 GuShH should I get a come-along and build a ramp.... an engine hoist wouldn't go high enough
15:20 Tom_itx muscle
15:57 GuShH Tom_itx: that's how I got the parts in...
15:58 GuShH but I don't know anyone strong enough to help with, everyone's a wimp
15:59 GuShH when we took it apart at the seller's house we were 4 and we had to take breaks after several steps
15:59 GuShH it was a terribly hot day and the guy had no ice cubes!
15:59 Tom_itx leverage
16:00 GuShH yes but I need to anchor the pedestal then
16:00 GuShH to use a ramp
16:00 Tom_itx you seem smart, i bet you figure it out
16:00 GuShH then I can wrap some PTFE rod underneath and it will slide without much effort, but it would also be dangerous without guides
16:00 Tom_itx i know i would
16:00 GuShH Tom_itx: if I had help I could wrestle the parts, but I'm doing it alone
16:00 Tom_itx we moved a bridgeport on water pipe once
16:01 GuShH yes that's how I'm moving everything
16:01 Tom_itx jacked it up with a pry bar to get it underneath
16:01 GuShH but, gas pipe.
16:01 Tom_itx same
16:01 GuShH works very nicely
16:01 GuShH but that's for sliding parts, I need to lift them :(
16:02 Tom_itx block and tackle
16:02 GuShH ain't got any rigging stuff
16:03 GuShH and based on the upcoming holidays... I won't be having anything any time soon
16:04 GuShH I'll need an anchor point on the floor so the pedestal won't tip over, then a ramp is my safest bet
16:04 GuShH this is when a fat girlfriend could come in handy, just have her sit on the part so it won't tip over.
16:04 Tom_itx heh
16:04 Tom_itx they cost too much
16:05 Tom_itx not a good investment
16:05 GuShH girlfriends? yes they do.
16:05 Tom_itx for the return, it's a horrible investment
16:05 GuShH in fact an escort, by the hour, costs less.
16:05 ShH chuc
16:05 GuShH one day I'll find that special one! and she won't be a guy wearing a wig.
16:06 Tom_itx once you're hooked then you will find out it wasn't that special
16:06 GuShH I think it was you who suggested I may be looking for a "pal" based on my search criteria
16:06 GuShH haha
16:06 Tom_itx wasn't me
16:06 GuShH aww then SpeedEvil
16:06 GuShH Long time ago.
16:07 GuShH I said I wanted someone with the same interests
16:07 Tom_itx ask rue about his recent endeaors
16:07 GuShH hmmm I know he was dating, kinda
16:07 GuShH what happened?
16:08 Tom_itx it stopped
16:08 Tom_itx i guess
16:08 GuShH ah he found out she wasn't a robot
16:10 GuShH I think my left knee disagrees with what I just did, now I'll be a lettuce for a couple days :(
16:11 GuShH so I couldn't remove the acme screw from a tailstock... I removed the setscrew it just wouldn't budge, put it on the press... it went "klonk" and it finally came out (cheater bar involved) inside I discovered a sheared screw...
16:12 GuShH the other half still threaded, drilled it out (first bit got caught when the screw began to spin and it broke off, but it wasn't stuck so I was able to remove it with another bit)
16:12 GuShH found out the trick is, after it was spot-drilled to use a sacrificial bit, ground slightly off center, so it will bite onto the screw and take it out
16:12 Tom_itx they make easy outs for that
16:12 GuShH (the hole was a pass-through so it just came out from the inside, you would need a left hand drill otherwise)
16:12 GuShH Tom_itx: they never work for me, and they have broken.
16:13 GuShH my biggest fear is when a hardened bit breaks and stays.
16:13 Tom_itx i've had good luck with em
16:13 Tom_itx edm it out then
16:13 GuShH quality must matter, I've used a borrowed set, must have been cheap
16:13 GuShH haha not everyone can edm...
16:13 Tom_itx afk a while now
16:13 GuShH anyway I'm just saying on a pinch the "offset bit" works, if the hole is threaded all the way
16:14 GuShH a drill with a clutch would be ideal there
16:14 GuShH I was wondering on the shear force for 5/16 all-thread (that's what it looked like, but it was most likely a cheap screw that sheared in the past)
16:15 GuShH the bottle jack is just 2T but that was enough to shear it
16:41 rue_more yaknow, if PET absorbs water, it expalins why a pop bottle put in a microwave shrinks so much
16:41 rue_more GuShH, real sheer sheer?
16:42 rue_more GuShH, allthread is rated for stretch load
16:42 rue_more tho I'd wonder how hard you have to turn a nut to get 2T sheer on the threads
16:47 rue_shop3 RifRaf, it arrived, 1Kg of 3mm ABS
16:47 rue_shop3 white
16:47 rue_shop3 armyofevilrobots, ^^ !
16:47 rue_shop3 recon I need to finish up that heated bed
16:48 rue_shop3 armyofevilrobots, cheers to amazon, got it here in a few days (tho they said it would be jan 2)
16:49 rue_shop3 hahah, wonder if there is printable panduit
16:50 rue_shop3 ooo there isn't!
16:55 GuShH rue_shop3: pics here: http://imgur.com/a/VtiS2 ... looks like an old setscrew that got damaged and they just tried to keep it locked with a SHCS on top, otherwise I'm not sure what's going on... I couldn't see it inside before, and when I pounded onto the shaft I noticed there had to be something in there, but it had no head so I couldn't remove it, decided to try my luck on the press.
16:55 GuShH they actually drilled and tapped onto the shaft... odd.
16:56 GuShH that aluminum piece is 1" rod for size ref only
16:56 GuShH this is the tailstock handle for the shorty lathe
16:57 rue_more why did they collar out the keyway?
16:57 GuShH I've no idea
16:57 GuShH but on other pictures the tailstock wheel looks similar, however something has been modified
16:57 GuShH probably a different screw
16:57 GuShH and nut
16:57 GuShH OR...
16:58 GuShH it is the original but it got marred / damaged and they decided to turn it down and sleeve it
16:58 GuShH who knows.
16:58 rue_more wait, I dont see a keyway in the threaded rod
16:58 rue_more is there one?
16:58 GuShH it could have been turned down enough where it disappeared
16:58 GuShH none, just a partially threaded hole, kinda on 45°
16:59 rue_more you cant sheer a keyway off on a hand wheel
16:59 GuShH the only reason I took this apart is because it had a lot of play where the wheel met the rod
16:59 GuShH if the keyway is the wrong size sure you can
16:59 GuShH err, the key.
16:59 GuShH it will roll-over
16:59 GuShH then damage the shaft
16:59 rue_more wait, wasn't the origional machine blue?
17:00 GuShH blue and orange
17:00 rue_more ok
17:00 GuShH but I don't know if that's the original color, nobody does.
17:00 GuShH blue-ish or green-ish for sure.
17:00 rue_more well the paint goes back
17:00 GuShH it could be this wheel isn't for this tailstock too, but it looks similar to the pictures of other lathes
17:01 GuShH at any rate, I don't know why it's so big
17:01 rue_more is the whole grubscrew provision post production work?
17:01 GuShH most likely
17:01 GuShH you can see the hole isn't even centered
17:01 rue_more maybe the origional was a keyway and retainer nut
17:01 GuShH this "mod" is terrible
17:01 rue_more the nut stripped?..
17:01 GuShH but the acme screw looks fine, the nut looks fine
17:02 GuShH who knows
17:02 rue_more no I mean a handwheel retainer nut
17:02 GuShH yeah
17:02 GuShH but good thing is... it's out.
17:02 GuShH not sure I'll go through the trouble of sleeving this thing
17:02 rue_more is the larger collar on the acme about the same as the orig hole?
17:03 GuShH more or less yes
17:03 rue_more huh
17:04 rue_more have another pic of the machine all togethor? from back a ways? older pic unassembled?
17:04 ShH is surprised his tiny bottle jack was able to shear that s
17:04 rue_more I cant see from the other pics, but the screw says that hole was really off
17:04 rue_more maybe it was hand drilled :)
17:05 GuShH based on the angle I would imagine so
17:05 GuShH but yeah I might go for blue when I finish the whole thing
17:08 GuShH rue_more: http://imgur.com/a/xk8HJ two older pics and one where you can see a terrible brazing weld (I assume that tailstock hit the floor once)
17:08 GuShH that round collar thing, not sure if it was part of a depth gage or what...
17:09 GuShH but yes, it is a metal spinning lathe, not sure why this one has a carriage, they usually have a toolpost like a wood lathe has, but beefier and with holes
17:09 GuShH friggin hilarious how short it is now
17:10 GuShH if anything I'll have a nice garden lathe.
17:11 rue_more do you ahve any pics to compare the legs to ther other lathe you found?
17:13 GuShH one sec
17:14 GuShH who knows why they shortened the bed...
17:14 rue_more you sound shure they did
17:14 rue_more ?
17:15 GuShH I'm sure now
17:16 GuShH old pic showing the legs and two pics from the small turret lathe, I painted it yesterday, working on details http://imgur.com/a/63xYR (I need to finish the inside of the bed)
17:17 GuShH the bearings need to be replaced, but other than that the whole thing is fine
17:17 GuShH just looking for chuck jaws... or a collet chuck
17:17 rue_more are the headstock end legs cast-in?
17:18 GuShH looks to be all one part
17:18 rue_more cause the tailstock end legs seem to be welded to a plate thats bolted on
17:18 GuShH the back one is, because the bed was shortened!
17:18 rue_more thats what I was just thinking
17:19 GuShH it's missing probably 40CM of bed, at least
17:19 rue_more that lathe has indeed been thru hell
17:19 GuShH originally you had 1 meter between centers for the regular model
17:19 rue_more I'm guessing it was worth scrap a few times
17:19 GuShH yeah
17:19 GuShH or less
17:19 GuShH but I'll make it work again, if anything just to see it working.
17:20 GuShH also I would like to try spinning some metal
17:20 GuShH I can make a toolpost for that
17:20 rue_more still have the link to that other one?
17:20 rue_more http://www.ebay.ca/itm/Du-Bro-Wire-Straightener-NO-5-TO-NO-15-gauge-single-strand-wire-/231359331280
17:20 rue_more ^^ good way to make money with a lathe at $16 ea
17:21 rue_more http://www.ebay.ca/itm/Artistic-Wire-Nylon-Wire-Straightener-/301176890755
17:21 rue_more or more
17:21 GuShH yeah but the other one is earlier and had weaker legs
17:21 GuShH but the bed matches
17:21 rue_more well lets see!
17:21 GuShH they changed the headstock and tailstock
17:21 GuShH https://lh6.googleusercontent.com/-0TuRtyFwVhY/VI6IRyUBWcI/AAAAAAAAA1I/1ySIXJOWwxk/w958-h716-no/image1.jpg
17:21 GuShH the support for the removable part of the bed had changed from square to round
17:22 GuShH however there's so little information I can only rely on what the other two guys are saying (we are 3 in total, nobody else knows of any other lathes of this kind)
17:22 GuShH origin: spain
17:22 GuShH based on what has been said, the company used the same beds for all of their lathe models
17:23 GuShH they made metal spinning lathes, wood lathes and some basic engine lathes
17:23 rue_more yea, I'm gonna guess they upgraded a wood lathe to make a matal lathe
17:23 GuShH but that slide seems original
17:24 GuShH it's one big casting
17:26 GuShH now, the wheel on the tailstock of the older versions was small, but someone suggested my tailstock may have the cross slide wheel mounted, since that is missing, the carriage wheel is the only one on the apron.
17:26 GuShH but anyway who knows. I just know it was abused to hell and back a few times.
17:27 GuShH either way the lesson here is that if the lathe has a solid spindle, it was either meant for wood or metal spinning
17:34 rue_more http://www.google.ca/imgres?imgurl=http%3A%2F%2F3.imimg.com%2Fdata3%2FFU%2FHU%2FMY-2715992%2Fgap-bed-lathe-machine-500x500.jpg&imgrefurl=http%3A%2F%2Fwww.indiamart.com%2Fmoliyaenterprise%2Flathe-machine.html&h=154&w=326&tbnid=z5RUN4WNb6dwiM%3A&zoom=1&docid=2JmX2AQVVxgdTM&ei=IrGUVIGPH8XroASGhIGACg&tbm=isch&ved=0CB0QMygVMBU49AM&iact=rc&uact=3&dur=973&page=29&start=517&ndsp=19
17:35 rue_more just an image they used, damn
17:36 rue_more http://www.lathes.co.uk/lorchschmidt/page3.html
17:36 rue_more hmm, thoughts?
17:36 rue_more I cant tell if thats technically more or less advanced
17:37 rue_more smaller, yes, but probably not coinncodently the same bed style
17:39 rue_more hmm acutally, that last image, the tailstock thing, I like that...
17:39 rue_more GuShH, I'm waiting for your feedback here
17:40 rue_more ok, I'v searched all the images in google, thats what I found
17:40 rue_more :)
17:49 Tom_itx rue_more's home early
17:59 rue_shop3 totally exhausted to the point of being useless
17:59 rue_shop3 I came home and slept for 4 hours
17:59 rue_shop3 I been up less than 1.5 hours and my eyes are already starting to snap closed
18:00 rue_shop3 I dont know much about whats wrong, but its annoying as hell
18:24 GuShH rue_more: sorry I went to the shop, was working on drilling and tapping the collet closer handle for the small turret lathe
18:25 GuShH it's fully tapered but I decided to chuck it from the threaded portion with an aluminum shim, then use the steady rest with lots of oil on the flattest part, so I could try to center and drill it (first I had to drill the old broken bolt out, then extract it, then find center --- found a center "ish" because the handle is slightly bent, but it worked out fine, spotted, drilled, then went to tap size and now I just need to tap it (1/2") for a stud
18:26 GuShH rue_more: I'm amazed by the size of the wheels on old lathes... they are MASSIVE
18:27 GuShH I might just reproduce one of these handles http://www.lathes.co.uk/lorchschmidt/img29.jpg
18:28 GuShH I'll have to wait until shorty is in working order, so I can make the parts there (I get extra points if I do that!)
18:29 GuShH Hyratel: went for blue... http://i.imgur.com/OriWQPO.jpg I'll probably use gray or red on the inside, been working on other parts though
18:33 GuShH rue_shop3: I wonder if I could resurface brake discs with shorty, that would be hilarious haha
18:33 GuShH usually though those lathes have 2 tools, one on each side, they typically face both ends at the same time
18:34 GuShH I've seen an angle grinder mounted on a toolpost to grind drums....
18:36 Hyratel looking nice
18:37 ShH actually spent very little time painting that thing, for what it's worth any fine finish will be promptly removed after the first
18:39 rue_shop3 I think it could do that!
18:40 rue_shop3 sturdier than most modern brake disk lathes I'd bet
18:46 GuShH rue_shop3: to produce those wire straighteners you need to stamp out the linkages, the rest is simple
18:46 GuShH however that's a low demand item
18:48 GuShH I'd rather have a tiny set of solid dies and pull them through that
18:48 GuShH but what do I know I don't work with wire or artsy things
19:03 GuShH well it does chuck the 11" discs I got here, of course I'm chucking them from the inner lip, which wouldn't work properly if you were going to resurface them you would most likely use a special arbor that also allowed you to indicate it properly
19:13 armyofevilrobots @rue_shop3: Awesome.
19:27 mbass watches another robot movie : Robot and F
19:27 rue_more hi kat!
19:28 rue_more I'm gonna go to bed in a min
19:28 rue_more got something zapping all my energy
19:28 rue_more came home from work at 10 this morning and slept for 4 hours
19:28 rue_more started getting tired again about 1.25hrs in
19:30 GuShH https://www.youtube.com/watch?v=rK8UIGkzsf8
19:36 rue_more hmmm
19:37 Tom_itx u up or down?
19:37 rue_more I'm going down
19:38 Tom_itx ur no fun
19:38 rue_more I dont want to be
19:38 rue_more my euyes keep closing
19:38 rue_more and I have a throbbing headache
19:39 Tom_itx sure not up to listening to mindless chatter from bama
21:10 rue_shop3 what are hot topics on obamas list?
21:11 rue_shop3 how to soften the blow from the death of the us dollar?
21:11 Tom_itx give america away
21:11 rue_shop3 heh, technically the chinese bought it
21:11 rue_shop3 well, technically the us gave it to them
21:12 Tom_itx tea worked ehh?
21:12 rue_shop3 I think I wanted the sleep
21:12 rue_shop3 Im in that state where I"m useless but cant sleep
21:12 Tom_itx i could go either way
21:13 Tom_itx lack the motivation to choose
21:13 rue_shop3 I been trying to mentally render a simple 3d clip, and I'm failing terribly
21:13 Tom_itx i'm somewhat inclined to rewire my box
21:13 Tom_itx well i could help
21:13 rue_shop3 yea, I took the reprap apart last night and added leds
21:14 Tom_itx what's the clip for?
21:15 rue_shop3 the idea is to clamp a 1/8" rod to a 5/16" all thread at 90* without haveing to slide over the end of the allthread
21:15 rue_shop3 much like the 90 degree clamps that currently exist on the reprap
21:15 rue_shop3 I"m drawing now
21:16 Tom_itx so make the 5/16 side 2/3 circle
21:16 Tom_itx are you gonna print threads on it?
21:16 rue_shop3 nono
21:17 rue_shop3 just clamp around the 5/16
21:17 Tom_itx i need more data
21:17 Tom_itx so i can draw
21:17 rue_shop3 hmm, dizzyness just went up to about 40%
21:17 rue_shop3 I think diagnosis is about 60% of treatment
21:18 rue_shop3 I think that 80% of the things I say have too many statistics in them
21:18 Tom_itx how long is the 5/16 rod piece?
21:18 rue_shop3 90% of my statistist are just estimated
21:18 Tom_itx how long is the 1/8 rod piece?
21:18 rue_shop3 its just two corossing bars
21:18 Tom_itx how far apart are the rods?
21:18 Tom_itx not touching?
21:18 rue_shop3 the idea is to join where they cross
21:18 rue_shop3 they dont ahve to touch
21:18 Tom_itx i got that picture
21:19 rue_shop3 as long as all the peices are consistant it dosn't matter
21:19 Tom_itx how thick wall?
21:20 rue_shop3 2mm min is a good idea
21:20 rue_shop3 much smaller than that and it dosn't print with any strength
21:20 Tom_itx now you're mixing fractions and mm
21:20 rue_shop3 I'M CANADIAN
21:20 rue_shop3 :)
21:20 Tom_itx what's 2mm in inch?
21:20 rue_shop3 about an eighth
21:23 rue_shop3 this would be easier if the 1/8 were threaded...
21:25 Tom_itx how long on each side?
21:25 rue_shop3 ?
21:26 Tom_itx how much plastic will cover each rod
21:26 Tom_itx 1"?
21:26 rue_shop3 just enough clamp to hold the crossing of the two bars togethor
21:26 Tom_itx .5"?
21:26 rue_shop3 about 1/4" min
21:26 rue_shop3 its just to hold rig for mounting pcb's to, its not gotta be really strong
21:28 rue_shop3 my scribbles are comming up with an idea
21:28 rue_shop3 hows you doin?
21:30 Tom_itx woops
21:30 Tom_itx i gotta move one of em
21:30 Tom_itx then i'm done
21:30 Tom_itx i'm not too good at solidworks yet
21:31 rue_shop3 practise makes
21:33 Tom_itx i'm gonna start over
21:33 Tom_itx i'll write the dimensions down first
21:43 Tom_itx ok
21:46 Tom_itx you there?
21:46 rue_shop3 yup
21:46 rue_shop3 I'm working on mine
21:46 rue_shop3 its.... kinda sideways
21:47 Tom_L http://tom-itx.no-ip.biz:81/~webpage/rue/Rue_connector.jpg
21:48 Tom_L .250 on each length
21:50 Tom_L hard to print though since it won't lay flat
21:52 Tom_L working on a fix
21:54 rue_shop3 ok, but it CANT require being slid over the end of the allthread...
21:54 rue_shop3 has to clamp on
21:54 rue_shop3 I'm playing with two peices that cross the two at 45
21:54 Tom_L i'm working on that too
22:19 rue_shop3 there is also some fun in making parts in a way such that there is as little bridging as possable
22:19 rue_shop3 makes yar think
22:19 Tom_itx i could have been done ages ago in my cad cam
22:24 rue_shop3 :)
22:26 Tom_itx figuring out how much 'snap' it needs to cross the bar and stay in place
22:27 rue_shop3 minimal if there is a almping screw ;)
22:27 rue_shop3 clamping
22:33 rue_shop3 hmmmm
22:45 fleshtheworld anyone have an overview explanation of what is involved with building a a cheap RC car from scratch?
23:01 rue_shop3 fleshtheworld, knowing how to build a kit is probably a good start
23:01 rue_shop3 Tom_itx, I think I might have something that works
23:01 rue_shop3 its composed of two peices, little strips with a clamp screw in each end, and a groove that fits the bar on its side
23:02 rue_shop3 shall I try to export an image?
23:02 Tom_L i have it drawn in my cad cam but can't export it to sw because it's not a solid
23:02 Tom_L it's just a 2d drawing
23:03 Tom_L this will work
23:03 Tom_L if i can reproduce it in sw
23:04 fleshtheworld rue_shop3, how is a typical kit? is everything premade work and fit perfectly together and then you just put them together?
23:04 rue_shop3 yea
23:04 rue_shop3 then you know what the peices generally are and how they go togethor
23:04 rue_shop3 you take your ideas on how to improve it, make your own kit and assemble it
23:05 rue_shop3 you keep doing till you have the perfect project
23:05 fleshtheworld and from there how do you get to making and or coding the chip, say for example i got a RC chip and assembled, it, how do i do go from that making a more complex machine
23:06 fleshtheworld opps i meant RC kit*
23:07 rue_shop3 go to ebay, type in the words "smart car"
23:07 fleshtheworld rephrase, how do i go from a RC kit to making a more complex machine, like say a humaniod or something less complicated
23:07 rue_shop3 sort by price+shipping, lowest first
23:07 rue_shop3 ?
23:09 fleshtheworld guess ill just have to give it a go, kit or no kit
23:09 fleshtheworld my goal is just to build machine, making an RC was just an example
23:10 rue_shop2 did you do that ebay search?>
23:11 fleshtheworld yeah
23:11 fleshtheworld i put in robot kit
23:14 rue_shop3 try the instructions, even if you decide to use your own way later
23:14 Tom_L i think i got it now
23:14 rue_shop3 go to ebay, type in the words "smart car", sort by price+shipping, lowest first
23:15 rue_shop3 Tom_itx, :)
23:15 rue_shop3 Tom_itx, I still have to finish that pen test file
23:17 fleshtheworld in general, do people just buy parts and assembled them together to make frankenstein machines? i mean most peoplt dont have the means to make their own parts
23:18 rue_shop2 I dont buy the parts, I take them off stuff
23:19 rue_shop2 http://ruemohr.org/~ircjunk/robots/robot_family2.jpg
23:19 rue_shop2 I REALLY have to update that image, maybe I'll have a lawn again this year
23:20 fleshtheworld man i really need to start getting into robotics
23:20 Tom_L i think that test will be impossible to do
23:20 Tom_L you need to calculate the extruder travel for each move
23:20 rue_shop2 each of those was done on a $20 budget
23:21 rue_shop2 Tom_itx, the postion delta to extruded material ratio will be the same
23:21 rue_shop2 I just work out what its using and write it in for each line
23:21 rue_shop2 its basically another axis, its interpolated with the xyz
23:21 Tom_L trouble extruding the 2nd half of this damn thing
23:23 rue_shop3 I think I'll start making a 2nd machine with my improvements
23:23 rue_shop3 I'v got a descent set of mods now
23:24 fleshtheworld hey, has anyone designed a RC whatever, where if it goes out of range, it can self control and retrack itself back
23:25 fleshtheworld to hopfully get back in range
23:26 fleshtheworld it would involve a bit of AI programming but that has always been a design i would put in my RCs
23:29 fleshtheworld i can add a memory on it where if it gets within 3 feet of the out of range zone it would record where it is going, then when it loses contact with the controller, it would just retrack
23:29 fleshtheworld anywho
23:30 Tom_L yay i got it
23:32 Tom_L http://tom-itx.no-ip.biz:81/~webpage/rue/Rue_connector.jpg
23:33 Tom_L http://tom-itx.no-ip.biz:81/~webpage/rue/Rue_connector2.jpg
23:34 Tom_L print it with the 1/8" hole horizontal
23:36 Tom_L http://tom-itx.no-ip.biz:81/~webpage/rue/Rue_connector.STL
23:39 Tom_L not sure you can use that format...
23:42 rue_shop3 nice!
23:42 rue_shop3 think it'll stay put?
23:42 Tom_L i'm not sure you can import that
23:42 Tom_L i have no idea how it'll print
23:42 Tom_L is that what you had in mind?
23:43 Tom_L i just exported an .igs file too
23:43 Tom_L you may be able to use that
23:43 rue_shop3 well, positive locking is good, but lets see if I can print it
23:43 rue_shop3 stl file is right
23:44 Tom_L i know but i'm not sure it looks ok in pronterface
23:44 rue_shop3 I'm just trying to figure that out
23:44 Tom_L did you import it?
23:44 rue_shop3 not yet, keep your lid on
23:44 rue_shop3 trying to figure out which way z is
23:44 Tom_L i did my part
23:44 Tom_L with the C flat
23:45 Tom_L and the 1/8" hole horizontal
23:45 rue_shop3 yup, I think its right...
23:45 Tom_L shouldn't take long to print
23:45 Tom_L if it works
23:46 rue_shop3 nope its laying wrong..
23:46 rue_shop3 needs to be 90* on around the X
23:46 Tom_L ask somebody how to move it
23:46 rue_shop3 dont know if I can do that
23:46 Tom_L i'm not sure how to in sw
23:47 Tom_L i remember somebody mentioning that about SW and pronterface
23:49 rue_shop3 I think I did it
23:49 rue_shop3 meshlab can do a lot of things, none of them seem usefull
23:50 rue_shop3 ok
23:50 Tom_L so you need it rotated 90 deg CW?
23:50 rue_shop3 thats oriented right
23:50 Tom_L ok good
23:50 rue_shop3 I rotated it 90 degrees around X
23:50 rue_shop3 your Z is the wrong way :)
23:50 Tom_L that would work
23:51 Tom_L since i drew it on center
23:51 rue_shop3 my Z is up, yours is forward
23:51 Tom_L ok
23:51 Tom_L so my SW 'front' plane is Z up
23:52 Tom_L maybe you should copy more than one to print
23:52 rue_shop3 setting up for print...
23:52 Tom_L it may do better
23:52 Tom_L i'm not sure that snap will be snug enough
23:53 rue_shop3 23cm of filament...
23:53 rue_shop3 heating.... heating...
23:53 Tom_L you need to get SW
23:54 rue_shop3 the printer mauls the sizes a bit
23:54 rue_shop3 SW?
23:54 rue_shop3 shockwave?
23:54 Tom_L solidworks
23:55 Tom_L haha it imported into my cad cam fine
23:55 rue_shop3 heh, its making a mess of the overhang, I really do need to do some bridge calibration
23:56 Tom_L i could macine them from HDPE
23:56 rue_shop3 I'm wondering if this will be too tight
23:56 e_shop3 waits for the pri
23:56 Tom_L i can work on the snap fit some i think
23:57 Tom_L just wasn't sure where to start
23:57 Tom_L you can file it out
23:57 Tom_L :D
