[01:18:03] <sector_0> hey guys
[01:18:21] <sector_0> I wanted to build a corexy machine for light milling
[01:18:48] <sector_0> the inspiration came from this
[01:18:49] <sector_0> http://corexy.com/corexyr1/index.html
[01:19:28] <sector_0> but when I milled my parts I didn't include connect the 2 y axis carriages
[01:20:06] <sector_0> I'm trying to connect 2 bars to synchronize the y axis carriage and remove the slop
[01:20:18] <sector_0> can I use JB Weld to attach this?
[01:20:52] <sector_0> the carriages are about 300cm (12 inches) apart
[01:21:19] <sector_0> I'm wondering if JB Weld will hold up to the torque
[01:29:21] <sadara> I have pretty much decided on a hardware setup for my next project (low cost multi channel servo/stepper drives with intergrated CNC controller)
[01:30:09] <sadara> an altera FPGA SoC with dual cortex-a9 cores, so there may be the possibility of running emc/machinekit on it
[02:10:57] <Deejay> moin
[03:19:41] <Mac_VMC> hi Deejay
[03:20:09] <Mac_VMC> if anyone is bored, and has a few minutes. please take a look http://linuxcnc.org/index.php/english/forum/49-basic-configuration/29681-allen-bradley-vfd-spindle-control#62968
[04:00:29] <Contract_Pilot> Quiet
[04:16:37] <fenn> can't be arsed to register to see some forum attachments
[04:23:29] <fenn> Mac_VMC: make sure motion.spindle-speed-out is connected to something
[04:32:17] <fenn> oh wow i am registered from 9 years ago
[04:35:48] <fenn> this is so complicated... you don't need PID to control a spindle
[04:41:09] <fenn> i want to say just do "net motion.spindle-speed-out hm2_5i25.0.7i77.0.1.analogout4" and delete the rest of that crap
[04:41:30] <fenn> but spindle-at-speed is kinda useful so keep that
[04:44:43] <fenn> in summary, i have no idea why your spindle doesn't move
[04:45:32] <fenn> Mac_VMC: what is "VFD-direct interface"? is that modbus, or setting the hal pin directly, or attaching a battery to the VFD or what?
[04:50:28] <fenn> also you could make sure that the hal stuff is behaving by typing in a terminal "halcmd show pin | grep spindle"
[04:52:08] <XXCoder> split so many rings
[04:52:35] <XXCoder> Sauron would cry
[05:28:34] <Sync> Mac_VMC: as I said yesterday, did you try to manually set the output voltage on the card?
[05:37:10] <jthornton> damn 0.2 away from breaking the 200 barrier
[05:41:11] <XXCoder> what 200 barrier?
[05:42:00] <jthornton> gravitational attraction to the earth
[05:43:01] <Jymmm> jthornton: just run backwards
[05:43:24] <malcom2073> Nothing repulses attraction like running backwards
[05:45:24] <XXCoder> no, run backwards to gain mass
[05:45:30] <XXCoder> go forwards to lose mass
[05:46:15] <XXCoder> run sideways to gain strength without mass change
[05:46:30] <jthornton> move to the moon
[05:47:21] <Jymmm> jthornton: Can't do that Dave, the O2 air (outter space) transport hazmat fees will kill ya
[05:47:40] <malcom2073> Run like Seagal: https://www.youtube.com/watch?v=nkskuSXqUD0
[06:40:41] <fenn> how hard is it to make an autocollimator? i mean come on, it's like some mirrors and glue and a laser pointer right?
[06:41:25] <fenn> i was going to buy a fancy straightedge to do straightness sanity checks but i'd rather rely on something less arbitrary
[06:44:37] * fenn is reading "foundations of mechanical accuracy"
[06:52:34] <fenn> moore is obsessed with double V-grooves, but never addresses the problems of kinematic overconstraint it introduces and the insane tedium of all that lapping and checking bearing masters and inverted masters and lapping masters
[06:53:15] <fenn> the whole process would be simpler if they just used a simpler way geometry
[06:53:30] <fenn> ideally just two flat surfaces
[06:53:39] <malcom2073> Tedium?? TEDIUM?!? There's no BOREDOM in lapping!
[06:55:24] <XXCoder> fenn: better than splitting 190 rings
[06:55:43] <XXCoder> and I got 110 to look forward to tomorrow. in least its overtime yay lol
[06:55:50] <fenn> i don't even know what that means
[06:56:28] <XXCoder> fenn: not very complex, just cut ring into 2 arcs. like lots other parts its not clear what its used for. lol
[07:40:35] <fenn> cool old books http://www.evenfallstudios.com/woodworks_library/woodworks_library.html
[07:41:14] <fenn> more necessary now that lindsay books went kaput
[07:50:05] <rootB_i> Hey linux CNC
[07:50:10] <rootB_i> where can i get tis screw for cheap
[07:50:17] <rootB_i> M5 x 20mm BHCS
[07:50:44] <Wolf_> cheap or soon?
[07:50:48] <rootB_i> well
[07:50:52] <rootB_i> useful with nice tolerance
[07:50:56] <rootB_i> im trying to rebuild my shapeoko
[07:51:06] <rootB_i> and i was using non BHCS screws so that brought me trouble
[07:51:08] <Wolf_> try mcmaster
[07:51:21] <rootB_i> mcmaster thinks im a terrorist and wont ship me..
[07:51:31] <Wolf_> oh
[07:51:41] <Wolf_> fastenal
[07:51:54] <rootB_i> does that happens often
[07:52:13] <Wolf_> no idea
[07:53:01] <rootB_i> i could buy them from inventables
[07:53:07] <rootB_i> but everything there is too fucking expensive
[07:53:18] <rootB_i> so im making a sacrifice buying the stuff i need from them already.. which is delrin wheels.
[07:53:32] <rootB_i> Im starting to think that rebuilding this CNC might be a mistake and that im better off buying a new one
[08:00:56] <rootB_i> what do you think inuxCNC
[08:02:49] <fenn> i think the shapeoko looks like crap
[08:03:25] <rootB_i> wel... yeah..
[08:03:52] <rootB_i> I want to use it as a CNC, but i gusess it only works as a good CNC
[08:03:57] <rootB_i> got any recommendations of what else i can buy fenn?
[08:05:21] <rootB_i> I'm all ears
[08:05:30] <fenn> what is your location, what are your goals and resources
[08:05:45] <fenn> do you want to make foam airplanes or cast iron blocks
[08:06:09] <fenn> or stainless steel blobs
[08:06:44] <rootB_i> well I can't make stainless steel stuff, CNC's of that grade are 50K+ USD
[08:06:46] <rootB_i> I live in Mxico
[08:06:52] <rootB_i> Mexico
[08:06:59] <rootB_i> I want to do wood stuff-Aluminium, etc.
[08:07:14] <fenn> are there used machine tools available around your area?
[08:07:37] <rootB_i> probably not, fenn stuff here gets re used to a point that it'll scare you
[08:08:03] <fenn> hm wood and aluminum, i guess you should fix the shapeoko then
[08:08:11] <rootB_i> Acrylic
[08:08:12] <rootB_i> etc
[08:08:34] <rootB_i> What's the cheapest entry tier machine for stainless steel-cast iron?
[08:09:23] <fenn> depends where you are; in the midwest or east cost USA you can get huge old WW2 milling machines for scrap price ($1-2k)
[08:09:24] <Wolf_> I wouldnt go smaller then a sieg x2 type (solid column preferred)
[08:09:34] <fenn> east coast*
[08:10:25] <rootB_i> dAMN
[08:10:30] <rootB_i> What about any CNC options?
[08:10:36] <rootB_i> i suppose that'll shoot up the price to 10k right?
[08:10:56] <Wolf_> 600-$800 maybe
[08:11:04] <Wolf_> tooling is what kills you
[08:11:13] <rootB_i> bits are expensive?
[08:11:51] <Wolf_> bits, holders, drills, hold downs, setup stuff, measuring gear, misc junk
[08:12:16] <rootB_i> I see
[08:12:20] <rootB_i> so that's around 1k i suppose
[08:12:35] <rootB_i> SO to get started in the stainless steel-cast iron is around 5k or so?
[08:13:22] <fenn> i've never actually added it all up
[08:13:29] <Wolf_> you can do it cheaper, there are ways to work around not having everything
[08:13:52] <rootB_i> I see
[08:14:05] <fenn> you can gear down underpowered motors and that reduces the cost of the whole CNC system, but it will be slow and annoying to use
[08:14:50] <Wolf_> run program, nap
[08:15:05] <fenn> there are a lot of ways to put "sweat equity" into cheap chinese tools to improve them
[08:15:10] <fenn> as wolf is learning :)
[08:15:31] <Wolf_> lol, by the time I’m done, i’m going to have 2 mills
[08:15:41] <fenn> it's a reprap!
[08:16:02] <fenn> repslap, a replicating slow prototyper
[08:16:09] <fenn> slop
[08:16:27] <rootB_i> wait that sieg looks awful like a machine ive seen on harbor freight
[08:16:40] <fenn> yes same design different level of quality control
[08:16:41] <Wolf_> right now I’m looking at cad screen on the other computer trying to figure out how the hell i’m going to make this x axis bearing block
[08:16:55] <Wolf_> rootB_i: thats cause it is
[08:17:23] <Wolf_> but they make like 5 different x2 variants
[08:17:32] <rootB_i> you got a link to the "proper version"
[08:17:38] <rootB_i> the one that wont murder me with a lose screw?
[08:18:22] <ganzuul> Acetal is expensive. :(
[08:18:56] <rootB_i> im checkingo ut prices to see how much I have to save
[08:19:20] <Topy44> hi
[08:19:34] <Topy44> i need something that looks roughly like this: http://dump.t44.org/2015-09-25_14-54-54.png
[08:19:39] <ganzuul> My Sieg hasn't murdered me yet.
[08:19:41] <Topy44> about 3-4mm diameter
[08:19:45] <Topy44> with a round recess
[08:20:02] <Topy44> i have no idea if such a part exists or what it might be used for if it does :)
[08:20:48] <rootB_i> i suppose an option like tornarch
[08:20:51] <rootB_i> is off the budget right
[08:20:59] <Wolf_> lol
[08:21:50] <fenn> i guess you are referring to the adjustable column angle
[08:21:52] <Wolf_> their tool holder concept is sound, think the machine is over hyped/priced maybe
[08:22:13] <rootB_i> man
[08:22:14] <fenn> http://littlemachineshop.com/info/minimill_compare.php
[08:22:19] <rootB_i> all this is ounding like its going to throw me down the street
[08:22:28] <malcom2073> Machine tools usually do heh
[08:22:31] <rootB_i> oh thanks, fenn
[08:23:03] <fenn> yep i've been reading for the past month about how to build machine tools because they don't appear on craigslist around here
[08:23:17] <ganzuul> Topy44: That shape could possibly be found in rubber, somewhere.
[08:23:22] <rootB_i> the closest craiglist i have is san diego
[08:23:23] <Wolf_> malcom2073: get your mill running yet? :P
[08:23:27] <rootB_i> and arizona
[08:23:30] <Topy44> ganzuul: ah, it should be metal
[08:23:34] <Topy44> steel or brass
[08:23:53] <malcom2073> Wolf_: Nope, waiting on adapter plates, and I have to make 2 more aluminum sleeves
[08:23:58] <fenn> so i'm thinking about using concrete castings and granite plates in clever ways
[08:24:46] <ganzuul> Topy44: how exactly round should the recess be?
[08:24:47] <Wolf_> man this x1 is gonna hate me…
[08:25:01] <rootB_i> https://phoenix.craigslist.org/cph/bfs/5237755594.html
[08:25:32] <fenn> that's too much machine for you anyway
[08:25:52] <Topy44> ganzuul: it doesn't actually matter much. essentially it will be pressed into 3d printed plastic and is there to keep an adjustment screw from slipping away. or something like that. its really hard to explain :)
[08:26:07] <Wolf_> I need to make a 22mm x 25mm part, all I have is 1.5” x4” x 12” alum bar stock
[08:26:16] <Topy44> it would be trivial to make a part like that myself, but i need something i can buy in quantity
[08:26:19] <fenn> "Machine is located in Minnesota" wtf are they doing advertising on phoenix craigslist then
[08:26:21] <malcom2073> Wolf_: Bandsaw
[08:26:25] <Topy44> but the exact shape doesn't actually matter
[08:26:51] <Wolf_> yeah, thats a lot of bandsaw time too lol
[08:27:07] <malcom2073> horizontal bandsaw :P
[08:27:16] <Wolf_> thats what I have
[08:27:16] <malcom2073> Set it and forget it
[08:27:32] <fenn> that's not a lot of bandsaw time, you have a giant bastard bandsaw
[08:27:41] <ganzuul> Topy44: Where in the world are you located?
[08:27:51] <Wolf_> that alum doesn’t cut that fast
[08:27:53] <Topy44> germany, why?
[08:27:58] <ganzuul> hm
[08:28:19] <ganzuul> I could make this.
[08:28:25] <fenn> turn it so the skinny side is up and down, to maximize pressure on the cut
[08:28:39] <Wolf_> I know how to use the saw lol
[08:28:47] <Topy44> well i could make this too. :) but it should really be a commodity part, as the design should be reproducible
[08:29:08] <Topy44> i need to find something preexisting that works
[08:29:17] <Wolf_> that thing has had about 4000lbs of steel through it already
[08:30:03] <malcom2073> Maybe you need the blade replaced?
[08:30:26] <Wolf_> new blade in it
[08:30:46] <Wolf_> but the blades I get are for steel
[08:33:10] <fenn> Topy44: how about using a socket head screw head
[08:33:35] <ganzuul> oh
[08:33:45] <Wolf_> 90% of the stuff that we cut here is c channel or square tube so I’m running 12/14 bimetal blades
[08:33:48] <Topy44> fenn: i thought about that actually
[08:34:27] <Wolf_> oops, 10/14 in the saw right now, 6-10 on the shelf
[08:35:16] <rootB_i> THANK YOU lINUXcnc
[08:35:23] <rootB_i> Now im understand the complex world of CNC machining.
[08:37:07] <malcom2073> Share your knowlege, because I still don't understand it heh
[08:37:11] * ganzuul tries to eat rootB_i's brain to gain his understanding
[08:37:21] <Wolf_> lol
[08:38:01] <rootB_i> this is literally the indusry of
[08:38:07] <rootB_i> "you get what you pay for"
[08:38:44] <Wolf_> to a point, pretty much, you can make do with cheap on somethings
[08:39:01] <malcom2073> And sometimes you can find good deals
[08:39:18] <_methods> auctions are your friend in this world
[08:40:09] <ganzuul> And moly lube too.
[08:40:15] <_methods> hahah
[08:40:17] <_methods> not that new shit
[08:40:23] <fenn> superlube
[08:40:27] <_methods> the old moly lube yes
[08:40:35] <fenn> black nasty stuff
[08:40:49] <fenn> my parents used to put it on my bike chain
[08:40:52] <malcom2073> Nonsense, Vactra!
[08:41:19] <_methods> anchor lube
[08:42:53] <Wolf_> I meant to order a sample of anchor lube (you all know they send out samples right?)
[08:43:22] <_methods> don't need samples when you have 1 gal bottles of it lol
[08:43:40] <Wolf_> lol
[08:45:51] <_methods> man i thought that episode of black mirror was just a joke
[08:45:55] <rootB_i> it takes me around 200 dollars
[08:46:00] <rootB_i> to rebuld my shapeoko
[08:46:05] <rootB_i> on mechanical parts
[08:46:09] <_methods> now i find out the PM is a porcine copulator
[08:46:21] <rootB_i> now i gotta see which driver to get and limit switches
[08:47:13] <fenn> rootB_i: you could make the wheels fairly easily out of delrin stock
[08:47:30] <rootB_i> i got no tools to get it machined
[08:47:41] <fenn> drill a hole for a bolt, grip the bolt in a power drill and machine it with a chisel
[08:47:57] <fenn> so-called "afghan lathe"
[08:48:12] <Wolf_> simple lathe is a easy build
[08:48:33] <fenn> yeah for bonus points make a lathe
[08:49:06] <fenn> it will be more useful than the shapeoko i bet
[08:49:54] <rootB_i> lol
[08:50:09] <fenn> there's nothing special about delrin either, it's just especially easy to machine
[08:50:23] <fenn> you can use cutting boards
[08:50:44] <Wolf_> cutting boards are HDPE I think
[08:50:57] <fenn> yes, of varying grades
[08:51:32] <fenn> shapeoko is aluminum V rails, so you can't run anything harder than aluminum or it will destroy the rails
[08:51:36] <Wolf_> I’ve used a few to make parts lol
[08:51:57] <rootB_i> fenn, Im aware of that
[08:52:16] <Wolf_> cutting boards that is, not the shapeoko
[08:52:30] <fenn> PVC is a little bit harder than HDPE
[08:52:53] <fenn> but higher friction
[08:53:28] <Wolf_> I bet the wheels are on bearings so that really shouldn’t matter
[08:54:37] <Wolf_> I have a i3v printer that uses the v slot extrude
[08:55:57] <rootB_i> well
[08:56:02] <rootB_i> I'll see how i can start fixing my shapeoko
[08:56:08] <rootB_i> its a little bit late so i gotta get ready for work
[08:56:15] <rootB_i> at least its not going to be godly expensive
[08:56:23] <rootB_i> I already go the drivers
[08:56:32] <rootB_i> they're the little chinese black boxes from Ebay, not the blue card.
[08:56:45] <fenn> you might also try making sliding bearings from cutting boards instead of wheels
[08:57:15] <fenn> i'm not sure which is worse
[08:57:20] <rootB_i> lol
[08:57:38] <rootB_i> don't 3d printers use sliding bearings
[08:57:46] <rootB_i> well 3d printings dont have to go thru all the stress
[08:58:29] <Wolf_> most use ball race linear, some use v grove wheels
[08:59:05] <rootB_i> But i mean, isn't that ok since it's a 3d priner
[08:59:10] <rootB_i> or it should use screws and all?
[08:59:19] <rootB_i> even the 3D system ones use bearings
[08:59:23] <rootB_i> i've take a look at them on expos
[08:59:32] <Wolf_> drive is belts on most printers
[08:59:52] <Wolf_> fast, no side load
[09:00:23] <malcom2073> If you use screws for X and Y, you need a high pitch screw
[09:00:30] <malcom2073> I have low pitch screws, and let me tell you, they have to spin REALLY fast
[09:03:16] <CaptHindsight> http://www.shapeoko.com/ but but but the website says "The Best CNC Machine in its Class. Period."
[09:03:28] <CaptHindsight> so it can't be a turd
[09:03:51] <Wolf_> thats cause its the only turd in its class...
[09:04:06] <fenn> kicksterter class
[09:04:55] <fenn> it really is better than a lot of the "CNC machine" being hyped on kickstarter
[09:06:14] <_methods> special ed class
[09:07:52] <CaptHindsight> "We don't want to sell you a machine if it won't work for you!" but no we won't take it back
[09:08:02] <CaptHindsight> if it doesn't
[09:08:29] <malcom2073> Technically your fault for buying a machine that doesn't fit your specifications :P
[09:09:28] <fenn> what bothers me is when they call it "a CNC" because it obviously isn't a milling machine, and it's a stretch to call it a router, and it's too inaccurate to call it an engraving machine
[09:09:32] <DaViruz> i'm sure their specificatinos on stiffness and wear rate is very.. specific
[09:10:29] <CaptHindsight> "we avoid telling you all that tech jargon so you can focus on making things"
[09:11:12] <DaViruz> Aluminum isn't an edge case for Shapeoko 3, and no special provisions need to be made to the machine. We eat aluminum for breakfast.
[09:11:17] <DaViruz> I think i want some salt with that breakfast
[09:11:49] <DaViruz> (though i am sure that machine will have a lot of uses for a lot of users)
[09:11:55] <Wolf_> foil still counts as aluminum
[09:15:48] <CaptHindsight> the router comes off so you can still use it as a router
[09:18:06] <CaptHindsight> http://www.automationtechnologiesinc.com/products-page/cnc-router/taig-gecko-cnc-mill-milling-machine-engraver-router
[09:18:19] <CaptHindsight> http://www.automationtechnologiesinc.com/products-page/cnc-parts/atc-tool-holder
[09:21:10] <CaptHindsight> looks like he stopped selling the shapeoko type machine frames
[09:21:38] <malcom2073> Nice tool holder, one of my first big projects after I make a table enclosure, is going to be converting my impact threaded draw bar into a proper air powered stud draw bar
[09:22:59] <CaptHindsight> http://www.ebay.com/itm/like/121395852283 MakerFoot - Revolutionize your Shapeoko or MakerSlide CNC
[09:23:53] <malcom2073> "We use knit gloves when handling to avoid fingerprints" "We do not technically deburr the cut ends,"
[09:24:18] <CaptHindsight> after minutes of study we realized that aluminum window frame can be sold as CNC machine framing
[09:24:31] <Wolf_> lol
[09:26:48] <fenn> 1 items similar to MakerFoot - shapeoko 2 pen holder attachment 3d printed $14.99 Buy It Now
[09:27:04] <malcom2073> The richest people make the most money off the fools
[09:33:35] <ganzuul> Brass brazing steel to steel with butane; no problem. :)

[09:56:15] * ganzuul found out his lathe has crash detection!
[09:56:33] <CaptHindsight> how so?
[09:56:55] <ganzuul> Ran the tool into the jaw when I turned the wheel the wrong way
[09:57:20] <ganzuul> Crappy jaw though so I'm not too bothered.
[09:57:24] <ganzuul> Tool's alright.
[09:59:21] <ganzuul> ...So the lathe just instantly stopped when that happened.
[09:59:42] <ganzuul> No gnashing of teeth.
[10:02:17] <malcom2073> That chicks name is dolphin....
[10:07:24] <ssi> ganzuul: is that "crash detection", or is that "not enough power to hurt itself" :)
[10:10:10] <CaptHindsight> I'd say "advanced anti-crash technology" or "crash protection"
[10:11:36] <archivist> the fun starts now, unloading a CMM on your own
[10:16:02] <ganzuul> :D
[10:16:07] <ssi> viel gluck
[10:16:51] <ganzuul> It chewed through the hex head of an M16 cheese grade bolt just fine. Just have to give it a steady supply of cuttin'ol.
[10:19:59] <ganzuul> ...but it might have been pointless. ;.;
[10:21:12] <enleth> ganzuul: is the lathe a Sieg?
[10:21:49] <ganzuul> enleth: yeah, Super C3, BLDC motor
[10:23:17] <enleth> ganzuul: yup, they all have crash detection
[10:23:40] <enleth> even the older brushed DC models had
[10:23:51] <ganzuul> cool :)
[10:24:12] <ganzuul> So http://imgur.com/MPVWfjq
[10:24:45] <ganzuul> The washer wobbles so much that if I machine it there will hardly be anything left...
[10:25:10] <enleth> it's funny on the C0. The motor is 120W, so I can actually stall it and trip the crash detection by grabbing the chuck hard with a bare hand.
[10:28:52] <ganzuul> It's weird though; when I machined the face the nuts sit on I had it aligned in the outside jaws directly.
[10:29:14] <Simonious> there's a joke in there somewhere..
[10:29:19] <ganzuul> So I would assume the error would have been corrected righ there.
[10:32:43] <Simonious> so if I do g92 x0y0z2 that defines the current position of the head assuming the offsets are set correctly, right?
[10:33:08] <fenn> ganzuul it looks like the nut is not seating correctly inside the washer
[10:33:19] <fenn> try turning down the end of the nut and flipping it around
[10:33:44] <ganzuul> hmm
[10:34:15] <cradek> Simonious: it sets a g92 offset such that the current coordinates become those given
[10:34:40] <gabewillen> Hello everyone, how do you add capture-position on the encoder component in pru-driven hal as there is no base-thread?
[10:35:34] <Simonious> cradek: ty
[10:35:38] <gabewillen> Its a simple counter-mode encoder and it does not require the qep interface.
[10:35:47] <cradek> you could just add a base thread if you need it
[10:36:00] <cradek> I don't know anything about pru or qep. are you asking about machinekit?
[10:37:00] <gabewillen> Yes this is my first time using it with ARM. I am very experienced with linuxcnc & hal on x86 and normally came here to ask a question. But if i'm in the wrong area i apologize.
[10:37:20] <sadara> what is the machinekit channel?
[10:37:52] <gabewillen> I didn't see one listed in the blog
[10:38:02] <cradek> I'm not sure if they have an irc channel. they use a google group thing I think?
[10:38:35] <gabewillen> just a mailing list. I was looking for a quicker response as i'm hooking a machine up at work on the clock.
[10:38:56] <ganzuul> fenn: You're right. adding a third nut to lock two together in the middle of the thread didn't help either...
[10:40:41] <gabewillen> I'll use cradeks suggestion for now. I'll consult the mailing list and modify if needed.
[10:40:51] <gabewillen> Thanks cradek
[10:41:15] <sadara> ganzuul, google jam nut, they are more complicated then you think, and your probably doing it wrong
[10:42:34] <sadara> gabewillen, nm, that was really random,
[10:42:46] <_methods> heh jam nut google possibly nsfw
[10:42:47] <_methods> lol
[10:43:09] <_methods> jackie trehorn present JAM NUT
[10:43:40] <ssi> :D
[10:44:13] <_methods> http://i.imgur.com/mO7uX79.webm
[10:44:24] <_methods> don't see that every day
[10:44:33] <ssi> have you seen the bouncy house one?
[10:44:37] <_methods> no
[10:44:47] <ganzuul> derp, I don't actually need a third nut for this.
[10:45:02] <ssi> https://www.youtube.com/watch?v=3fEQMZNwZGc
[10:45:18] <_methods> hahahha
[10:45:23] <_methods> i need a trex suit
[10:45:27] <ssi> yussss
[10:45:40] <_methods> omg trex makes the bed
[10:45:41] <_methods> hahahah
[10:51:12] <ganzuul> fenn: I can't find any information about that I could have done wrong... I tightened the two nuts against each other harder than I tightened the workpiece to one of them.
[10:52:02] <ganzuul> derp
[10:52:08] <ganzuul> sadara: ^
[10:53:16] <sadara> ganzuul, ?
[10:54:30] <sadara> tighten the first nut
[10:54:43] <sadara> tighten the second nut and hold
[10:54:57] <sadara> LOOSEN the first nut
[10:55:56] <ganzuul> oooh, right. I can use two wrenches.
[10:58:09] <sadara> the torque between the two nuts has to be more than between the nuts and the workpiece. I've never actually seen anyone use jam nuts correctly
[10:58:49] <ganzuul> That's what I did. :)
[10:59:29] <ganzuul> The concept is pretty simple. It's an anti-backlash scheme.
[10:59:58] <_methods> wtf are you tryin to do? turn the washer OD down?
[11:00:13] <ganzuul> No, true up the face
[11:00:25] <_methods> the face of a washer?
[11:00:30] <ganzuul> yeah
[11:00:35] <ssi> how are you going to true under the nut?
[11:00:37] <_methods> why in the world would you do that?
[11:00:59] <ganzuul> To get my bench grinder to vibrate less.
[11:01:05] <ssi> if that's really a thing you want to do, you're probably better off with a superglue arbor
[11:01:14] <_methods> just make a washer from bar stock then
[11:01:20] <ganzuul> hm
[11:01:30] <malcom2073> Is the washer the problem, or the (significantly heavier) stone?
[11:01:41] <_methods> if you need a dimensionally perfect washer
[11:01:49] <ganzuul> I was going to get some Delrin today but balked at the price. :V
[11:02:13] <ganzuul> malcom2073: I think it's the washer. It makes the stone wobble.
[11:02:18] <ganzuul> It's stamped steel.
[11:02:33] <_methods> what about the bushing?
[11:02:47] <_methods> that's usually where wobble comes in on the grinder
[11:02:52] <ganzuul> _methods: Glued into the stone.
[11:02:55] <_methods> and a badly ground stone
[11:03:03] <_methods> just true up the wheel
[11:03:38] <ganzuul> I'ma try wrapping some copper tape around the axle.
[11:03:47] <ganzuul> Get the bushing tighter...
[11:03:54] <_methods> that's a good idea
[11:04:49] <CaptHindsight> why bargain grinders and stones might not be bargains
[11:05:06] <roycroft> bargain stones tend to blow up
[11:05:36] <CaptHindsight> heh, I needed one on a Sunday and the HF wheel just about did that
[11:06:15] <roycroft> if you're going to buy a bargain stone the prudent thing to do is to mount it up, then turn on the grinder and run away as fast as you can and wait about 5 minutes while it spins up to speed and holds speed for a while
[11:09:44] <ganzuul> I switched up the 200W/150mm bargin grinder for a 370W/200mm one.
[11:10:41] <ssi> my HF grinder is pretty ok but the stones that came with it I'm pretty sure they make by taking an 8" holesaw to the pavement behind the factory
[11:11:45] <CaptHindsight> the tolerance on the mounting holes mist be +/- .25"
[11:12:38] <CaptHindsight> I'm surprised there aren't lawsuits over the carnage caused by them coming apart
[11:14:08] <ganzuul> me too
[11:15:31] <_methods> yeah i had to make new bushings for my HF grinder
[11:15:50] <ssi> my hf grinder has some kind of chinese superbearings in it
[11:15:52] <_methods> that solved a lot of the problems
[11:15:55] <ssi> when I shut it off, it'll spin for two hours
[11:15:58] <ssi> not even exaggerating
[11:16:02] <_methods> hahah
[11:16:10] <_methods> it's a perpetual motion machine
[11:16:12] <ssi> yep
[11:16:13] <_methods> free energy

[12:20:31] <Tom_itx> you'd be nuts to fly with him
[12:20:42] <ssi> a friend of mine owns that airplane now
[12:21:02] <ssi> and I'd LOVE to have the opportunity to fly with the guy in the video :D
[12:21:05] <ssi> he was one of the best
[12:21:15] <Tom_itx> _was_ ?
[12:21:21] <ssi> I dunno if he's alive or not
[12:21:25] <ssi> he was a million years old in the 80s
[12:21:28] <Tom_itx> oh
[12:22:28] <ssi> yea they're both dead now
[12:22:29] <ssi> 2000
[12:24:09] <Tom_itx> accident on takeoff?
[12:25:15] <ssi> not sure what happened... some kind of accident training
[12:25:48] <ssi> midair looks like
[12:26:08] <ssi> which isn't terribly surprising... their signature was very very close formation aerobatics, often with Daniel inverted
[12:26:15] <ssi> https://upload.wikimedia.org/wikipedia/en/6/63/FrenchConnection.jpg
[12:28:29] <malcom2073> Hey, that guys post has Andy's mini mill
[12:28:34] <malcom2073> his hobbing video, I like that one
[12:29:22] <MattyMatt> ssi, I've heard that long spindown is a sign of worn out bearings. my tablesaw does the same. 2 minutes+
[12:29:34] <ssi> MattyMatt: interesting
[12:29:52] <ssi> I dunno that they're worn out, they were probably born that way
[12:29:54] <ssi> it's always done that
[12:31:21] <CaptHindsight> nah just no load on them
[12:31:41] <MattyMatt> if they had the preload you expect from good bearings, they'd have a tiny bit of rolling resistance. and all that grease they should be moving
[12:31:57] <CaptHindsight> is the balls and races are round but there's room between balls it should spin like that
[12:32:03] <CaptHindsight> is/if
[12:32:32] <CaptHindsight> I'm starting think I have some S/F key dyslexia
[12:32:40] <ssi> lol
[12:32:50] <MattyMatt> dystypian nightmare
[12:40:15] <SpeedEvil> I have an azerty canadian keyboard.
[12:40:20] <SpeedEvil> Set to US-english.
[12:40:22] <SpeedEvil> In the UK.
[12:40:39] <SpeedEvil> Actually looking at the keys _really_ confuses me.
[12:40:59] <ssi> I'm a dvoraker
[12:41:11] <ssi> I switched in 2000
[12:41:24] <ssi> originally I rearranged my keycaps but I found it kept me from learning, I would just look
[12:41:30] <ssi> so I removed all the keycaps and learned to touchtype
[12:41:34] <ssi> took me two weeks of being useless
[12:41:50] <ssi> but I can type considerably faster in dvorak than I ever could qwerty
[12:42:02] <ssi> and I was already developing RSI then, and I was 20
[12:42:11] <ssi> now, it's been 15 years and I don't have wrist pain
[12:42:27] <ssi> and I'm a programmer by trade :P
[12:42:59] <SpeedEvil> How many programming tasks are actually limited by typing speed though?
[12:43:10] <ssi> not many
[12:43:18] <renesis> programmers who can type are pretty impressive
[12:43:19] <ssi> but efficient typing certainly helps
[12:43:29] <renesis> its certainly in significant savings in time
[12:43:42] * renesis cant rly type, like 20-30wpm but errors
[12:43:51] <SpeedEvil> renesis: Sure - to a degree.
[12:43:52] <renesis> s/in/a
[12:43:54] <ssi> I can type 140wpm error free if I concentrate
[12:44:02] <SpeedEvil> I mean - if you're at 15wpm - that's going to slow you down.
[12:44:04] <CaptHindsight> I just avoid typing in general
[12:44:10] <SpeedEvil> 50WPM+ - not so much
[12:44:10] <renesis> which basically means he isnt thinking about typing
[12:44:21] <renesis> and i think thats the big diff
[12:44:44] <renesis> like, i think about syntax, formatting, programmers who are typing that fast cant be very much
[12:45:20] <ssi> that stuff becomes muscle memory
[12:45:23] <SpeedEvil> Especially when you should be thinking most of the time about ways to avoid typing.
[12:45:27] <ssi> and it's tied in heavily with the environment you work in
[12:45:32] <ssi> I'm an old school vi guy
[12:45:49] <renesis> i really loved vi when i was using it daily
[12:45:50] <ssi> SpeedEvil: it's not so much about avoiding typing as it is avoiding work
[12:45:54] <ssi> the best programmers are the lazy ones
[12:45:58] <SpeedEvil> (ways to avoid typing = thinking about the code, not thinking about typing the next line)
[12:46:04] <renesis> there was a point where id catch :wq at the end of word docs
[12:46:04] <SpeedEvil> ssi: yeah - that
[12:46:12] <ssi> renesis: yeah I do that constantly
[12:46:20] <ssi> I can only use editors that have vi bindings
[12:46:29] <ssi> I mostly use sublime text these days, and it has vi bindings
[12:46:35] <renesis> does vim fuck you up in non compatible mode?
[12:46:46] <ssi> no actually I prefer the vim extensions
[12:46:54] <renesis> okay youre not that messed up
[12:46:57] <ssi> I haven't worked on honest to god neckbeard vi in AGES
[12:47:09] <Sync> it is painful
[12:47:38] <Tom_itx> i remember waking up after dreaming of code in the middle of the night and coding it. some of the best ideas came to me then
[12:47:52] <ssi> well one of my limitations is, as a dvorak guy, the hjkl movement keys in vi don't work for me
[12:48:04] <ssi> so I am one of those non-pure vi guys that uses arrow keys
[12:48:27] <Sync> me too, I cannot stand the hjkl crap
[12:49:00] <Sync> but I also don't like to touchtype for a long time
[12:49:07] <malcom2073> nano!
[12:49:09] * malcom2073 hides
[12:49:10] <ssi> I exclusively touchtype
[12:49:16] <SpeedEvil> I do too.
[12:49:20] <SpeedEvil> And touch-mouse.
[12:49:29] <CaptHindsight> avoiding typing has helped my wrists and hands, and avoiding programming has helped my joy in life
[12:49:40] <ssi> my boss thinks I'm super weird because I'll be on IRC talking to you guys, and he'll walk up and want to talk to me, and I'll look up and stare at him while he's talking and be blathering at you guys at 80+wpm
[12:49:42] <SpeedEvil> I frequently use the keyboard - with a trackpoint - under the bedclothes. Nice and warm in winter.
[12:50:09] <Sync> it makes my wrists hurt when I touchtype too long
[12:50:15] <Sync> and I'm plenty fast without it
[12:50:23] <ssi> Sync: switch to dvorak! fixed my pain
[12:50:23] <ssi> heh
[12:50:35] <SpeedEvil> I touchtype, but do not use a consistent home position.
[12:50:41] <Sync> well, if I type regularily I don't get any pain
[12:50:50] <SpeedEvil> At the moment, my fingers are over qwdf, kp=]
[12:51:26] <ssi> aoeu htns :)
[12:51:31] <Sync> I'd rather use qwertz with the neo sublayers
[12:54:10] <Sync> because they are useful when coding
[12:54:28] <ssi> dvorak isn't super useful for coding as a layout... it's optimized for english
[12:54:30] <ssi> but it works for me
[12:54:30] <Sync> but my muscle memory has huge issues adapting to different layouts
[12:59:07] <MattyMatt> chording keyboards are still a thing, allegedly
[12:59:21] * SpeedEvil prefers powerchording keyboards.
[12:59:30] * SpeedEvil turns his keyboard up to 11.
[12:59:33] <ssi> I have some time on a twiddler
[12:59:35] <MattyMatt> should be built into the arm of every chair
[12:59:45] <ssi> I don't think I still have it, it almost certainly was lost in the fire
[12:59:49] <ssi> but I got up to 15wpm on it at one point
[13:00:00] <SpeedEvil> I used to have a Microwriter Agenda
[13:00:18] <SpeedEvil> - the first commercial chorded keyboard thing
[13:00:28] <SpeedEvil> I think I only hit about 8wpm.
[13:00:36] <MattyMatt> if it was tapped on your forarm, you could still do it if your hands had been lost in the fire too
[13:01:12] <MattyMatt> finger muscles up by the elbow
[13:02:21] <SpeedEvil> The hand is a fucking awesome mechanism.
[13:02:31] <ssi> indeed
[13:02:36] <MattyMatt> christopher pike had less kit than steven hawking. 2 beeps for no?
[13:03:08] <SpeedEvil> https://en.wikipedia.org/wiki/Carpal_tunnel
[13:03:42] <SpeedEvil> https://upload.wikimedia.org/wikipedia/commons/f/f0/Carpal-Tunnel.svg
[13:04:07] <MattyMatt> if you tapped the nerves in the arm, you wouldn't have to actually move the fingers at all, at least not enough to draw the tendons tight
[13:04:26] <SpeedEvil> If only nerve interfacing was a bit easier.
[13:05:00] <MattyMatt> I thought eeg probes worked well enough stuck on the skin
[13:05:21] <MattyMatt> at least enough to detect if a whole muscle is firing
[13:05:25] <SpeedEvil> Sure.
[13:05:38] <SpeedEvil> i was meaning more bidirectional and sensitive, and many channel.
[13:06:03] <MattyMatt> one per finger, open loop will do for now. it's only typing :)
[13:06:24] <MattyMatt> cyborg gauntlets later
[13:06:45] <MattyMatt> bbl sausages
[13:40:26] <ganzuul> I'm not grinding another parting tool EVER again if I can help it.
[13:40:41] <ssi> lol
[13:40:58] <ganzuul> But I did discover that if I apply enough pressure, the tool bit doesn't get hot very quick.
[13:49:43] <JT-Shop> pos case power supply only has one sata plug... wtf everything is sata now a days
[13:58:42] <anomynous> ganzuul, why not
[14:03:05] <ganzuul> anomynous: It's very tedious. And the bench grinder makes a mess.
[14:03:26] <ganzuul> I need to construct some manner of containment for that thing.
[14:03:35] <anomynous> its tedious only after 3 first ones. After that they start to work ;D
[14:03:38] <anomynous> probably
[14:04:01] <anomynous> well, i cant grind either, though ive done... two? ;D
[14:04:16] <ganzuul> Then we're on par.
[14:04:55] <ganzuul> My first one, the usual workhorse shape, actually works well. Cuts the type of steel they make bolts of.
[14:05:21] <ganzuul> Nice tightly curling chips which break ok.
[14:05:21] <anomynous> i took a bit of a thick chip with drill today. I mismeasured the drill and it was feeding on slowest rapid ;D
[14:05:27] <anomynous> didnt break
[14:05:31] <anomynous> i was fast enough
[14:05:36] <ganzuul> :D
[14:06:39] <ganzuul> It's sort of awesome and humbling when you mistakenly push your tools and they still do what you ended up asking of them.
[14:08:06] <ssi> it's good to find your limits :)
[14:14:01] <archivist> a few cock ups during the learning phase is normal
[14:14:02] <ganzuul> Speaking of,
[14:18:22] <ganzuul> My brass/bronze brazing rod arrived. It works just fine to braze with a not-minmal butane torch.
[14:18:22] <ganzuul> So that's a pretty cool ability to have...
[14:18:24] <CaptHindsight> archivist: did you manage to get the CMM home?
[14:19:36] <anomynous> https://www.anony.ws/i/2015/09/25/20150925_120745.jpg
[14:20:46] <ganzuul> anomynous: That's a nail.
[14:21:00] <anomynous> really? its fe52 and it came out with the drill in the picture ;D
[14:21:31] <ganzuul> I have discovered a new way to make nails.
[14:21:46] <anomynous> ;D
[14:32:49] <ganzuul> ...I? I meant you.
[14:33:00] <ganzuul> weird
[14:33:17] <ganzuul> Coulda sworn I wrote 'you'.
[14:39:12] <archivist> CaptHindsight, its home, out the van, jacked downwards, about to go back on rollers then into the garage
[14:40:12] <archivist> its is never the 2 tons as the seller emailed more like 500kg
[14:40:59] <archivist> must make a universal wheeled trolley for this sort of occasion
[14:42:09] <archivist> CaptHindsight, despite the seller saying no probe, it had gained one today when I arrived :)
[14:42:10] <andypugh> archivist: Did you see mine?
[14:42:21] <archivist> your trolley, yes
[14:42:39] <andypugh> Yes, I meant my trolley.
[14:42:56] <CaptHindsight> archivist: \0/
[14:43:47] <archivist> have taken a few pics but getting dark and just getting a drink then onto rolling for an hour or something
[14:43:51] <MacGalempsy> good afternoon
[14:45:38] <andypugh> archivist: What be the machine?
[14:46:40] <archivist> andypugh, http://www.ebay.co.uk/itm/221868431124 the dalek
[14:46:58] <archivist> small working area though
[14:47:08] <archivist> volume
[14:49:24] <andypugh> What’s the plan for it?
[14:50:20] <archivist> will try its own software for a giggle and learning, then linuxcnc maybe
[14:50:49] <archivist> lots to learn first
[14:52:18] <SpeedEvil> archivist: 'universal wheeled trolley'. The hard part is the self-driving, so you can just have it drop the machine in your workshop.
[14:53:10] <SpeedEvil> archivist: nice
[14:53:31] <SpeedEvil> stupid title
[14:54:29] <ssi> http://www.xkcd.com/1579/
[14:54:36] <ssi> this is true for tech but it's also true of my machine shop
[14:54:42] <ssi> I spend FAR more time making tools than I do making products
[15:02:27] <malcom2073> SSI: I'm going on 6 months of working on machines to work on machines to work on machines
[15:02:41] <malcom2073> I bought a lathe, so I could make parts for my mill, which still isn't running :P
[15:03:05] <malcom2073> Amusing related: A friend of mine asked wtf these machines were for, best answer I could give her: Making parts for other machines
[15:03:05] <ssi> man I've been in that cycle for seven years
[15:03:17] <malcom2073> Hey, I'm new to the hobby, cut me a break :P
[15:03:36] <ssi> well I have zero fully functional cnc machines at the moment :)
[15:03:36] <malcom2073> Though you give me hope, that I won't run out of things to do with the machines :P
[15:04:09] <ssi> no, but you will develop a desire for bigger and more complicated machines :)
[15:04:24] <malcom2073> Hey, I went straight off for the CNC mill, I figure too much bigger and I'll need a thicker concrete pad
[15:04:32] <ssi> remind me what machine?
[15:04:37] <andypugh> I am finding that the machines you have are never big enough to make parts for the machines you have.
[15:04:37] <malcom2073> Clausing Kondia FV-1
[15:04:46] <malcom2073> Beefy knee mill
[15:05:00] <ssi> aha
[15:05:02] <ssi> that's a nice machine
[15:05:06] <ssi> about the size of by bridgyclone
[15:05:38] <ssi> see I'm up to this size now: https://scontent-atl3-1.xx.fbcdn.net/hphotos-xlt1/v/t1.0-9/10672253_10100490548539302_6407225546292985700_n.jpg?oh=34f31bdb74be027796e93c16365f7d6a&oe=56993952
[15:05:42] <andypugh> Currently trying to mill a 12”x12”x7” gearbox on a mill with a 12” x 8” x 8” envelope…
[15:05:42] <ssi> heh
[15:05:56] <malcom2073> Heh
[15:06:01] <malcom2073> This thing has a stupid large envelope
[15:06:01] <ssi> about 10klb
[15:06:09] <malcom2073> Haha nice
[15:06:16] <ssi> that one is 20x20x20" envelope
[15:06:17] <bjmorel_work> Does anyone know if the Spindle output on a 7i76 can handle -10/+10VDC ?
[15:06:19] <ssi> and 15hp, 10krpm
[15:06:21] <andypugh> ssi: Photoshop!
[15:06:21] <malcom2073> Nice!
[15:06:51] <ssi> andypugh: huh?!
[15:07:04] <andypugh> bjmorel_work: No, it’s a digital potentiometer
[15:07:28] <andypugh> ssi: The fork lift looks like it should be falling on its nose.
[15:07:50] <ssi> andypugh: the forklift weighs 20klb
[15:08:09] <ssi> it's a 12,500lb rated truck
[15:08:25] <ssi> and it was a tricky lift, because I had to get it from the front, but all the weight is in the back
[15:08:28] <ssi> with 8' forks
[15:08:40] <andypugh> Yeah, I wasn’t really saying I didn’t beleive it, just that forkifts often look wrong. They lift cars with them at work, from the front.
[15:08:42] <ssi> when I picked it up off the flatbed, I couldn't get all the way under it, and the back wheels came off the ground
[15:08:58] <ssi> I had to carefully scoot it back enough to reposition the forks deeper
[15:09:34] <bjmorel_work> andypugh: I mean using it like that, -10VDC to SPINDLE- and +10VDC to SPINDLE+
[15:10:01] <bjmorel_work> andypugh: The docs say it works for -5/+5, just wondering if it would reach.
[15:10:43] <andypugh> If it works for +/-5v can you reconfigure the drive to work at that scale?
[15:11:14] <andypugh> (It might be worth checking if the device is rated for 20V)
[15:11:20] <bjmorel_work> Not sure yet. Just got the AMC drive in via. UPS today. Waisting time at work thinking about it.
[15:15:25] <ssi> On Sunday, astronauts aboard the International Space Station got a sneak preview of a movie before it was released in theatres. The only problem is that movie was “The Martian”, a tale about an astronaut stranded alone on Mars, left for dead. It doesn’t exactly seem like appropriate viewing for those currently in space.
[15:15:30] <ssi> lol
[15:15:57] <SpeedEvil> ssi: Followed up by 'the andromeda strain'
[15:16:01] <ssi> :D
[15:16:11] <_methods> lol
[15:16:19] <_methods> and gravity
[15:16:41] <_methods> spaceman triple terror feature
[15:18:04] <ssi> Dr. Spaceman
[15:18:25] <CaptHindsight> and every Twilight Zone episode about stranded spacemen
[15:22:44] <malcom2073> Do any shops still use manual mills? Or is pretty much everything commercial cnc?
[15:22:50] <malcom2073> erm
[15:22:50] <malcom2073> lathes
[15:22:51] <malcom2073> not mills
[15:22:54] <malcom2073> Same question though
[15:23:14] <ssi> absolutely
[15:23:30] <malcom2073> I was standing at my lathe turning my motor sleeves, and I have my southbend set up across from the big one, and it looks like a shop, kinda cool
[15:23:34] <ssi> in fact I'd say only production shops really focus on cnc
[15:23:36] <[cube]> manual lathe is essential
[15:23:41] <roycroft> i would say that more machine shops use manual lathes than use manual milling machines
[15:24:05] <andypugh> Kieth Fenner certainly uses both
[15:24:11] <andypugh> (Keith)
[15:24:34] <andypugh> I rather suspect that capstan lathes are no longer used much for mass production.
[15:24:56] <andypugh> But for one-off and repair work a manual lathe is still useful.
[15:25:04] <malcom2073> Cool
[15:25:21] <malcom2073> I need to figure these DRO slides out and get this on my lathe, makethings much easier
[15:25:35] <ssi> andypugh: by capstan lathe, do you mean like the hardinge second-op lathes with the lever-op turret?
[15:26:00] <andypugh> Having said that, everything that can be done on a manual lathe can be done on a CNC more easily, with the right macros set up.
[15:26:35] <andypugh> ssi: Yes, the ones with a big slide and screw stops rather than mircometers.
[15:26:42] <ssi> yeah
[15:26:53] <ssi> that's a pretty antiquated production technique these days
[15:27:26] <andypugh> https://www.youtube.com/watch?v=EqRMwU1AuDg
[15:28:35] <roycroft> this is for sale locally:
[15:28:38] <roycroft> http://eugene.craigslist.org/tls/5216912026.html
[15:28:55] <roycroft> i could probably get it for about $2k, but i would have nowhere to put it, nor the means to move it
[15:28:56] <roycroft> it is HUGE
[15:29:24] <roycroft> i looked at it while picking up some other tooling at the estate that's being sold
[15:29:59] <roycroft> i think a wall of the bulding that it's in would have to be torn down to remove it
[15:30:56] <CaptHindsight> I come across similar ones for free if I will "just get it outta here"
[15:31:22] <roycroft> it would probably cost me $2k to move it
[15:31:47] <roycroft> it's been for sale for a while, and the folks do want to clear out the shop
[15:32:36] <CaptHindsight> warner swasey as well
[15:32:48] <roycroft> they have a frankenstein vertical milling machine that's actually interesting
[15:32:55] <roycroft> manex with a bridgeport head
[15:33:01] <roycroft> http://eugene.craigslist.org/tls/5216909807.html
[15:33:10] <roycroft> it's not in great condition though
[15:33:27] <roycroft> but it would be much easier to move
[15:33:36] <roycroft> and i would not mind getting a 9x42
[15:33:42] * ganzuul tricks out his lathe with the best bling. xD
[15:33:43] <roycroft> if i could get it for $1k i'd think about it
[15:33:55] <CaptHindsight> I wouldn't pay more than 2K together and delivered
[15:34:12] <roycroft> i don't live in the rust belt
[15:34:30] <roycroft> machinery is a bit more scarce in my part of the world than elsewhere, and more expensive for that reason
[15:34:45] <roycroft> if i were in ohio i would expect that to be almost free
[15:35:15] <CaptHindsight> yeah, WI, IL, MI, OH, IN
[15:35:22] <roycroft> pa
[15:37:54] <CaptHindsight> http://chicago.craigslist.org/wcl/bfs/5219944788.html
[15:38:55] <CaptHindsight> "also serves as a background prop for submarine films"
[15:42:42] <ssi> lol
[15:42:51] <ssi> southbends are better for that
[15:42:57] <ssi> every submarine I've ever been on had a southbend on it
[15:46:10] <roycroft> good ballast, those southbends
[15:48:42] <zeeshan> its the WEEKEND!!!!!!!!!!!!11
[15:48:58] <ssi> it is indeed
[15:49:11] <ssi> weather is crappy though :(
[15:49:22] <roycroft> it's kind of raining here a bit
[15:49:22] <jdh> super crappy here.
[15:49:27] <roycroft> but not enough to be useful
[15:49:56] <zeeshan> its pretty nice here all weekend
[15:50:04] <zeeshan> im looking forward to working on this vape handles
[15:50:08] <zeeshan> and hopefully finishing them off this weekend
[15:50:09] <zeeshan> long shot
[15:50:11] <zeeshan> but will try :P
[15:50:11] <jdh> damned druggies
[15:50:20] <zeeshan> i know =/
[15:50:33] <ssi> oh THATS what they were
[15:51:21] <zeeshan> ssi
[15:51:26] <zeeshan> why are you dissing my hairy hands
[15:51:32] <zeeshan> they are very useful in canada
[15:51:38] <andypugh> Bck to that video, it gets interesting when they get on to plugboard and actual early CNC: https://youtu.be/EqRMwU1AuDg?t=15m25s
[15:51:43] <ssi> yes I know they're functional
[15:51:51] <CaptHindsight> 72F here and sunny
[15:51:54] <ssi> and I wasn't dissing them, simply remarking on them :)
[15:51:57] <zeeshan> haha
[15:52:04] <zeeshan> dude
[15:52:06] <zeeshan> in grade 7
[15:52:08] <zeeshan> i had full facial hair
[15:52:13] <ssi> makes me want to go home and watch the hobbit
[15:52:17] <zeeshan> most people didnt even hit puberty
[15:52:20] <ssi> lol
[15:52:38] <zeeshan> which also meant i was messing with some highschool girls :P
[15:53:01] <malcom2073> And by messing, he means getting in trouble for peeping in their shower
[15:53:08] <zeeshan> haha
[15:53:16] <zeeshan> i always got made fun of for being hairy
[15:53:21] <zeeshan> i didnt mind :P
[15:53:33] <zeeshan> back then most of the girls were into hairy guys
[15:53:34] <zeeshan> ahha
[15:53:43] <zeeshan> now days they're into girly men :(
[15:53:48] <ssi> SWEET
[15:54:13] <zeeshan> i think i upset my coworker today
[15:54:21] <ssi> I do that on the regular
[15:54:24] <zeeshan> by calling a switch gear an overly sized residential panel
[15:54:25] <zeeshan> :(
[15:54:29] <ssi> I upset 70% of the people I talk to
[15:54:33] <zeeshan> -a switchgear
[15:54:46] <zeeshan> yes you have more eddys and stuff
[15:54:53] <zeeshan> but essentially i would think the concept is the same
[15:54:59] <zeeshan> they're circuit protection devices
[15:55:02] <zeeshan> and power routing devices
[15:55:08] <zeeshan> just very large ones
[15:55:20] <ssi> I'm sure they'll get over it :P
[15:55:21] <CaptHindsight> thin skinned engineers? never!
[15:55:28] <ssi> I'm going home!
[15:55:49] <jdh> excellent idea.
[16:20:19] <jdh> amazon is going to deliver 2 $0.91 thrust bearing washers to me sunday.
[16:20:31] <jdh> for free
[16:23:43] <andypugh> And that is one of many probles with this world :-)
[16:25:21] <jdh> the real problem is I am buying them for work because our purchasing system won't even get an order placed until Tuesday or so.
[16:28:55] <andypugh> Our purchasing system is great. It is absolutely impossible for me to buy anything, so I either don’t do it, or buy it with my own money. That saves the company a fortune, I am sure.
[16:29:17] <jdh> that could be the rationale for ours.
[16:29:46] <jdh> if a vendor will not accept our absurd terms, we have to buy through a third party that marks thigns up 18%
[16:29:53] <roycroft> i do a lot of personal purchasing and then expensing for a government that i work for on contract
[16:30:10] <roycroft> because their purchasing process is so difficult and excludes many vendors
[16:30:18] <roycroft> but it's easy for them to do expense reimbursements
[16:30:33] <roycroft> ebay is a good example - they cannot purchase anything off of ebay, even for $0.01
[16:30:37] <andypugh> Yes, everything we buy from RS Components is bought through a third-party company. I can’t see how that saves money.
[16:30:46] <roycroft> i buy them stuff all the time on ebay and save them heaps of money
[16:31:26] <SpeedEvil> andypugh: But they give the purchasing manager a new ipad.
[16:31:36] <SpeedEvil> With eight lines of cocaine already on it
[16:32:01] <andypugh> (I do work for quite a bg company, it’s probably a yacht)
[16:38:50] <andypugh> I have decided I like my SpaceNavigator 3D mouse thingy, it’s lovely for moving CAD models around
[16:43:24] <Deejay> gn8
[16:45:54] <JT-Shop> lovely to return the totally useless case it will cost me $25 to return a $49 case!
[16:45:58] <XXCoder> andypugh: I love my logtech darkfield mouse
[16:46:09] <XXCoder> jezz
[16:46:14] <XXCoder> as well as use it for various projects
[16:46:32] <XXCoder> (was thinking pc case but maybe not lol)
[16:46:58] <andypugh> I think that’s a different thing. The SpaceNavigator goes in the non-mouse hand, you use both at the same time.
[16:47:14] <XXCoder> ahh
[16:48:11] <andypugh> Pull it towards you, it zooms, twist it, the part rotates on a vertical axis, tilt it, on a horizontal axis, push sidways without tilting, pan sideeays. Etc.
[16:48:32] <JT-Shop> well I can use UPS and ship it back for $20...
[16:48:34] <andypugh> So, a full 6DOF (and two programmable buttond)
[16:48:53] <Tom_itx> JT-Shop, https://www.youtube.com/watch?v=g99lUtjLfMU&feature=youtu.be
[16:48:53] <XXCoder> andypugh: can turn it on or off? because wouldnt want end with mess as I type in irc or something lol
[16:49:50] <JT-Shop> Tom_itx, that you?
[16:50:02] <Tom_itx> that's me
[16:50:09] <JT-Shop> nice
[16:50:21] <JT-Shop> spindle complains a bit at that rpm?
[16:50:37] <Tom_itx> the spindle motor stalls until the PID gives it enough oomph to do it
[16:50:43] <Tom_itx> but it's a good thread
[16:51:05] <XXCoder> huh I see weight on one side. counterweight for spindle?
[16:51:11] <Tom_itx> uh huh
[16:51:18] <Tom_itx> for Z
[16:51:34] <XXCoder> nice
[16:51:35] <Tom_itx> works better with it
[16:51:38] <XXCoder> more accurate I guess
[16:52:00] <Tom_itx> may not do alot of tapping.. but it works
[16:52:19] <andypugh> XXCoder: It does specific things in specific apps.
[16:52:22] <JT-Shop> can you plug a USB 2 into a USB 3?
[16:52:26] <XXCoder> ok
[16:52:29] <XXCoder> JT-Shop: yes
[16:52:32] <Tom_itx> yes i don't see why not
[16:52:37] <Tom_itx> it's backward compatible
[16:52:44] <XXCoder> it wont gain much speed boost but it will work
[16:52:52] <XXCoder> it will max out usb 2.0 speed
[16:52:55] <JT-Shop> ok, looking for a new case for the gigabite
[16:53:24] <Tom_itx> i need about a 2hp spindle motor :D
[16:53:39] <andypugh> The fact that the spindle stalls and it still works makes it a better demo
[16:53:42] <Tom_itx> or a servo on it instead
[16:53:51] <Tom_itx> yeah i agree
[16:54:13] <Tom_itx> and once it goes, it speeds beyond the rpm until the pid levels out again
[16:54:52] <Tom_itx> i won't use it on thick material for sure
[16:57:25] <Tom_itx> i did have to adjust my accel limits on Z after updating to 2.7.0 with the TP
[16:57:36] <Tom_itx> X and Y seem to be ok
[16:59:20] <Tom_itx> mmm twin engine cessna crashed 2 mi N of the airport after takeoff today
[16:59:24] <zeeshan> andypugh: exactly
[16:59:26] <zeeshan> thats pretty awesome
[17:00:39] <archivist> first lump in the garage :)
[17:03:21] * JT-Shop wonders what size power supply a miniatx mb and dvd drive really need?
[17:03:26] <XXCoder> https://youtu.be/CCDIuZUfETc
[17:03:42] <Tom_itx> JT-Shop, get one of those PICO psus
[17:04:07] <Tom_itx> mini ATX? i've got one on my Mini ITX
[17:04:17] <Tom_itx> 120W
[17:04:21] <Tom_itx> 12v wart
[17:04:38] <JT-Shop> now my online store is going wonkers
[17:05:04] <Tom_itx> http://www.mini-box.com/s.nl/it.A/id.417/.f?sc=8&category=13
[17:05:11] <Tom_itx> i'm using that on this PC
[17:05:20] <Tom_itx> P1900
[17:05:40] <Tom_itx> runs 24/7
[17:06:02] <Tom_itx> err Q1900M
[17:06:07] <enleth> so *this* is making those funny noises - the upper spindle bearing is clanking and has 2mm of axial play.
[17:06:30] <enleth> fortunately it's a standard 6206
[17:06:42] <Tom_itx> enleth, my friend rebuilt his recently but i didn't see how it came apart
[17:06:57] <Tom_itx> the bridgeport?
[17:07:01] <JT-Shop> not enough plugs on that one
[17:07:01] <enleth> yep.
[17:07:26] <JT-Shop> now PHP upgrade to 5.6 is what hosed my store
[17:07:39] <Tom_itx> wonderful
[17:07:46] <enleth> Tom_itx: the spindle is super easy to remove and the upper bearing comes off easily
[17:14:23] <XXCoder> what do you think guys http://glowforge.com/
[17:16:30] <SpeedEvil> http://imgur.com/gallery/3oW9IgP sweeet machine
[17:17:20] <XXCoder> quite literally
[17:25:19] <zeeshan> lol
[17:25:22] <zeeshan> whats going onthere
[17:25:24] <zeeshan> im so confused
[17:25:32] <zeeshan> is that a candy maker
[17:26:25] <ssi> https://pbs.twimg.com/media/CPx9-LAWcAEEYq8.jpg:large
[17:26:29] <ssi> clampz!
[17:26:31] <zeeshan> nice!
[17:26:37] <zeeshan> flea market finds?
[17:26:40] <ssi> ebay
[17:26:43] <zeeshan> how much
[17:26:50] <ssi> like $30/pair shipped
[17:26:58] <zeeshan> exp
[17:27:01] <ssi> meh
[17:27:02] <zeeshan> but those starrets are brand new
[17:27:02] <ssi> i wanted some
[17:27:03] <zeeshan> nice
[17:27:13] <zeeshan> anything inthe starrett box?
[17:27:20] <ssi> no that's just the box the starret clamps go in
[17:27:23] <zeeshan> i had clamps that looked like that
[17:27:26] <zeeshan> but much rustier
[17:27:32] <zeeshan> it might be worth throwing em in some zep purple cleaner
[17:27:33] <ssi> I was thinking about making some
[17:27:35] <zeeshan> for an hour
[17:27:38] <roycroft> it's the weekend!
[17:27:44] <ssi> it'd be a fun heat treat / tooling project
[17:27:45] <roycroft> time to head out to the shop and have some fun
[17:28:07] <ssi> but those big 5" guys are pretty cool
[17:28:23] <ssi> they're shopmade I'm pretty sure, and the threads aren't super smooth, but they're big and beefy
[17:28:56] <JT-Shop> ssi what do you do for a gui in go?
[17:29:16] <roycroft> i made those parallel clamps in machining class
[17:29:22] <roycroft> one of the earlier projects we made
[17:29:24] <zeeshan> the bottom two pairs
[17:29:30] <zeeshan> dont look shop made
[17:29:36] <ssi> JT-Shop: web if anything
[17:29:37] <zeeshan> they're very much like brown and sharp
[17:29:51] <ssi> JT-Shop: there may be some toolkit bindings but I haven't messed with them
[17:30:04] <ssi> zeeshan: the medium sized ones? I agree
[17:30:25] <ssi> JT-Shop: I'm really hoping someone comes up with a nice binding for go to cocoa for writing native osx gui apps
[17:30:56] <JT-Shop> I looked but didn't see anything, however I can run go from python
[17:31:15] <ssi> lol for that matter you could have done the dxf parser in python
[17:31:58] <JT-Shop> I've looked at one done in python but it is very slow
[17:32:09] <ssi> ah
[17:32:31] <ssi> I was messing around yesterday with the idea of doing a state machine parser for dxf
[17:32:38] <ssi> I don't really know enough about the format tho
[17:32:49] <ssi> and i was too covered up with regular work to dive into the spec
[17:37:38] <Praesmeodymium> my 2 cents about glowforge, looks like a simple laser etcher, other than the mac level user friendly and some fancy software for those cameras the underlying concept is old.
[17:38:00] <XXCoder> Praesmeodymium: yeah price is pretty good too
[17:38:12] <XXCoder> is there cheaper nonchinese lasers?
[17:39:20] <ssi> Praesmeodymium: the concept of laser cutters you mean? nothing groundbreaking at all
[17:39:25] <ssi> it's interesting what they're doing with the cameras tho
[17:40:45] <Praesmeodymium> and cutting leather they nake look super easy its not, and its also stinky and may or may not release some nasty depending on the tanning method and dyes
[17:41:01] <ssi> I haven't found and real specs on it yet but it sounds like it's a diode laser
[17:41:04] <ssi> it can't be that powerful
[17:41:18] <XXCoder> Praesmeodymium: yeah I dont think I plan to do any leather
[17:41:54] <ssi> honestly the more I read the more it sounds like vaporware
[17:42:01] <ssi> I don't think they've selected a tube tech yet
[17:43:42] <ssi> hm maybe I'm wrong
[17:44:15] <Praesmeodymium> they have working models from the looks of it and that head could be a 2w laser or so I mean ya can jam a much larger bar diode in there with some lenses but something about that head shape reminds me of a 2w ir diode cutting thing I saw on ebay for 300$
[17:44:46] <XXCoder> interesting
[17:45:14] <ssi> yeah but a 2W diode isn't going to cut 1/4" plywood like they claim to
[17:45:21] <ssi> I'm sure they are using a 40W chinese tube
[17:45:36] <ssi> I found something that said the basic is 40W and the pro is 45W
[17:45:48] <ssi> but another thing they said was confusing was that the basic was certified as a class 1 laser product
[17:46:00] <ssi> and I didn't think you could have a 40W CO2 laser that was class 1
[17:46:38] <Praesmeodymium> I notice no real time cutting of cardbord. that shit is way tougher than most people realize when it comes to resisting a laser... oh the tube is shown across the back
[17:46:38] <XXCoder> does enclosure and protected mean can class 1 or does it depend on only strength of laser itself?
[17:46:39] <ssi> maybe they can consider it class 1 if all the necessary guards are in place and there's interlocks
[17:46:49] <ssi> XXCoder: yea that's what I was just thinking
[17:46:50] <Praesmeodymium> and I was wrong rewatching the vid
[17:47:16] <ssi> but that doesn't make sense either becaues they said the basic is class 1 and the pro is class 4... if the only difference was 40W vs 45W CO2 tube, there'd be no distinction in class
[17:47:39] <XXCoder> unless pro has MUCH less safe case. lol
[17:47:45] <XXCoder> honestly dunno
[17:47:47] <ssi> yeah but why would they do that
[17:48:06] <ssi> honestly the enclosures aren't that important
[17:48:10] <Praesmeodymium> 50% off preorder sale... thats som suspicous shit right there
[17:48:16] <ssi> I mean, they are for a commercial product like that because most people are idiots
[17:48:36] <ssi> but a running, aligned laser cutter doesn't pose much exposure risk other than actually sticking your hand in the beam
[17:48:40] <ssi> (which I did once)
[17:49:13] <Praesmeodymium> spckle from wood products under a 40w is certainly arc welding spot bright
[17:49:31] <ssi> eh maybe... it's tiny though
[17:49:36] <Praesmeodymium> I have a auto darkening shield in place on mine for that reason
[17:50:18] <Praesmeodymium> I wonder if it has air assist
[17:50:23] <XXCoder> im not too concerned about burns
[17:50:40] <enleth> Praesmeodymium: what kind of cardboard did you mean? I was cutting some corrugated cardboard on a chinese 40W and it cuts super fast and super clean
[17:50:42] <XXCoder> I'm VERY concerned about my eyes. I didnt get full senses array as you guys do lol
[17:51:03] <enleth> The edges are not burned at all, they look as if magic was used to disappear the rest of the sheet
[17:51:45] <Praesmeodymium> I was cutting something like the particle board of paper the heavy grey non corrugated stuff is tougher than acrylic by thickness
[17:52:25] <enleth> Ah, OK
[17:52:32] <enleth> This cuts worse than plywood
[17:54:01] <ssi> Praesmeodymium: doesn't look like it has air assist
[17:54:13] <ssi> in one of the videos the smoke looked fairly undisturbed
[17:54:17] <ssi> and they don't mention anything about shop air
[17:54:36] <Praesmeodymium> thats gonna eat lenses
[17:54:36] <enleth> How does it prevent the lenses and mirrors from getting fogged?
[17:54:52] <XXCoder> know what
[17:55:01] <XXCoder> I bet you software is properity as hell
[17:55:08] <Praesmeodymium> for sure
[17:55:16] <ssi> oh I'm sure
[17:55:19] <enleth> XXCoder: as is the chinese crap
[17:55:34] <Praesmeodymium> I have a damn security dongle lol
[17:55:36] <enleth> The one I have needs a hardware key to work
[17:55:39] <enleth> yeah, this one
[17:55:41] <ssi> HAH
[17:55:43] <ssi> that's horrible
[17:55:51] <enleth> It's a piece of shit that returns a static ID
[17:55:54] <enleth> But still
[17:56:00] <enleth> And the software itself...
[17:56:05] <enleth> There are three packages
[17:56:07] <Praesmeodymium> no shit
[17:56:08] <XXCoder> I bet you its emulatable enleth
[17:56:14] <ssi> my machine ran on linuxcnc
[17:56:18] <XXCoder> expecially if youre on linux
[17:56:29] <ssi> 24x48" working area, 120W RECI
[17:56:29] <enleth> One is a Corel Draw plugin that gets everything backwards
[17:56:44] <enleth> Second one is a chinese pseudo-CAD with no English language
[17:57:08] <enleth> Third one is a chinese pseudo-CAD with English language, but the only vector format it can import is WMF
[17:57:15] <XXCoder> ssi: nice!
[17:57:28] <Praesmeodymium> moshidraw, the plugin for corel12, and I have something I cant remember the name of POS
[17:57:31] <ssi> I need to build another one
[17:57:43] <ssi> as soon as I get the money the bank owes me, I'm gonna start on it
[17:57:55] <enleth> Apparently what you do when you get a chinese laser is ditch the controls and retrofit your own
[17:57:56] <ssi> thinking about buying a 48x96" cncrouterparts motion kit and using that
[17:58:22] <Praesmeodymium> still have to do that part, but I have air assist now
[17:58:29] <ssi> or maybe I'll just do another 24x48" machine
[17:58:33] <ssi> it'd be a LOT simpler
[17:58:34] <enleth> Unfortunately, the one I have here was bough with European Union money so it needs to retain all warranty stickers for a year
[18:03:39] <XXCoder> anyway
[18:03:56] <XXCoder> is there any machines at 1k to 2k range that dont require me to rebuild?
[18:04:27] <ssi> you could scratchbuild one for 2k or so if you were really frugal
[18:04:35] <ssi> 40W tube and power supply is ~$200
[18:04:58] <XXCoder> the biggest problem is I wouldnt be able to run machine without enclosure and I suck on building
[18:05:09] <ssi> mirrors, mirror mounts, head, and lens is around $175
[18:05:25] <ssi> just get some laser goggles
[18:05:27] <ssi> $40
[18:05:42] <ssi> that's what I did... I wore the goggles while I was testing and aligning
[18:05:47] <ssi> and once it was running well, I quit wearing them
[18:06:12] <XXCoder> I would wear it at all times while its running
[18:06:20] <ssi> feel free
[18:06:29] <XXCoder> excepton is if its completely enclosed
[18:06:31] <XXCoder> and closed
[18:06:41] <ssi> also I built my machine out of aluminum extrusion, and the original plan was to put polycarbonate sheet in the slots
[18:06:45] <ssi> I even made a lid for it
[18:06:53] <ssi> but the polycarbonate never happened
[18:07:27] <XXCoder> does linuxcnc support stopping when lid is opened, assuming there is input
[18:07:35] <ssi> sure
[18:09:46] <XXCoder> gonna love hacker problem solving https://imgur.com/gallery/dcdGJ
[18:09:55] <ssi> https://pbs.twimg.com/media/Bsiuo-fIIAAPOu0.jpg:large
[18:10:11] <XXCoder> I see the towers
[18:10:28] <ssi> https://pbs.twimg.com/media/Bsxx-rSIAAAnbro.jpg:large
[18:10:35] <ssi> I was trying to find a pic of the lid but I don't see one
[18:10:49] <ssi> https://pbs.twimg.com/media/Bs4lnp8IUAITlXH.jpg:large
[18:10:57] <ssi> htere you can see the lid in the background with lexan in it
[18:11:01] <ssi> with the protective sheeting still on it
[18:11:04] <XXCoder> yeah
[18:11:16] <XXCoder> it looks strightforward. how much was it
[18:11:24] <XXCoder> roughly
[18:11:29] <ssi> I dunno
[18:11:30] <ssi> a lot
[18:11:40] <ssi> https://vine.co/v/M26PDi1d1Z0
[18:11:47] <ssi> testing cheap safety glasses to see if they're laser safe
[18:12:23] <ssi> https://vine.co/v/M26P0FjeqAz
[18:12:26] <ssi> test firing the 40W
[18:12:45] <XXCoder> wow
[18:12:54] <ssi> https://vine.co/v/M2ttM75gljp
[18:13:00] <XXCoder> theres lots of laser diodes at aliexpress
[18:13:01] <ssi> there's the infamous video that made zeeshan hate me
[18:13:06] <XXCoder> those claim 500w and so on
[18:13:07] <DaViruz> just don't set anything on fire again ;)
[18:13:18] <ssi> DaViruz: well setting things on fire is sort of the point of the process
[18:13:32] <DaViruz> i suppose
[18:13:46] <XXCoder> ssi: I can turn that into perfectly seamless loop lol
[18:13:52] <ssi> XXCoder: my lasercut sextant: https://pbs.twimg.com/media/BvAkHSIIMAE9PxN.jpg:large
[18:14:01] <XXCoder> easy. just do one direction, then run it backwards
[18:14:07] <ssi> with 1 arcminute vernier scale: https://pbs.twimg.com/media/BvAkPmGIYAAbdEh.jpg:large
[18:14:08] <XXCoder> it will loop without break
[18:14:21] <XXCoder> nice!
[18:15:01] <XXCoder> ssi: just slow down last 2 frames so it dont suddenly jerk to right again
[18:15:03] <DaViruz> just beware of humidity changes ;)
[18:15:09] <ssi> https://pbs.twimg.com/media/BwplQ4aIYAE0nCc.jpg:large
[18:15:14] <ssi> the 40W tube next to the 120W tube
[18:15:17] <XXCoder> also slow down first 2 frame and tweak timing a little
[18:15:22] <DaViruz> but that engraving looks pretty darn crisp
[18:15:25] <ssi> DaViruz: you measure the index error of a sextent on every reading
[18:15:31] <XXCoder> DaViruz: yeah!
[18:15:54] <ssi> https://pbs.twimg.com/media/BwtW8w4CQAAJDh6.jpg:large
[18:16:09] <DaViruz> but what's up with the inner rings on the zeroes?
[18:16:12] <DaViruz> looks a tad offset
[18:16:28] <ssi> that's a good question
[18:16:28] <XXCoder> oh its not gif
[18:16:45] <ssi> I think it has to do with the order of the toolpaths
[18:16:51] <ssi> and the material may have moved sligchtly between
[18:16:58] <XXCoder> ssi: or repeatability issue
[18:16:59] <DaViruz> that'd do it
[18:17:20] <XXCoder> outer then while later inside for example, after long movement error built up?
[18:17:28] <ssi> yeah maybe
[18:17:34] <ssi> https://pbs.twimg.com/media/BxXKXHtIIAAZJ_n.jpg:large
[18:17:39] <ssi> lazrcut speaker boxes
[18:17:47] <ssi> I'm very proud of that design lol
[18:17:50] <XXCoder> nice
[18:17:57] <ssi> no glue
[18:18:03] <DaViruz> ssi: did you salvage any of the laser machine?
[18:18:06] <XXCoder> im pretty sure theres a way to test repeatability
[18:18:09] <ssi> I mean they'd be glued on assembly, but tehy fit tight like a puzzle
[18:18:12] <ssi> DaViruz: yeah!
[18:18:16] <ssi> the linuxcnc configs!
[18:18:19] <ssi> they're in git :D
[18:18:24] <DaViruz> :D
[18:18:29] <XXCoder> what happened to machine
[18:18:36] <XXCoder> oh fire?
[18:18:36] <ssi> there were some chunks of extrusion that didn't melt completely
[18:18:44] <ssi> and I found one end of the tube, and the inner resonator tube
[18:18:48] <XXCoder> yeah I remember you saying about fire
[18:19:17] <DaViruz> i keep two co2 extinguishers i my basement shop ever since..
[18:19:25] <ssi> I'm glad I could help :)
[18:19:32] <XXCoder> ssi: I noticed odd thing though. 6 has no hole
[18:19:34] <ssi> I have two extinguishers in my hangar too
[18:19:38] <XXCoder> makes it bit odd
[18:19:39] <ssi> XXCoder: yea I saw that too
[18:19:42] <ssi> could have been a sheetcam issue
[18:19:51] <ssi> or whatever I drew it in
[18:19:57] <XXCoder> it may be also reason for 0
[18:20:01] <ssi> yep
[18:20:21] <ssi> https://pbs.twimg.com/media/Bz3pFfnIEAAjxJd.jpg:large
[18:20:49] <XXCoder> do you put something under the mesh so it dont cut floor?
[18:21:05] <ssi> well, that's a sensitive subject :)
[18:21:08] <DaViruz> :D
[18:21:18] <XXCoder> lol
[18:21:53] <zeeshan> only fools need 1338ipm
[18:21:56] <ssi> the bed was 1/2" aluminum honeycomb (expensive shit!) sitting on 16ga expanded steel
[18:22:01] <ssi> zeeshan: DIAF
[18:22:05] <zeeshan> hahahahahaha
[18:22:19] <ssi> and then 20mm of air gap, and then 1/4" plywood on the bottom with a fan duct in it
[18:22:42] <ssi> and the cause of the fire was changing to a longer lens that caused a more focused spot on the plywood, and doing loooong cuts
[18:23:39] <XXCoder> ouch
[18:23:42] <ssi> originally I didn't have the expanded steel, the honeycomb sat directly on a piece of 1/4" ply that I lasercut a million 1" holes in, like a wood grating
[18:23:52] <ssi> and I was using short enough lenses that even that wasn't an issue
[18:24:29] <ssi> with a 1.5" or even 2" lens, it's diffuse enough after 1/2" to 3/4" beyond the focal point that there's not much power density
[18:25:13] <ssi> but start pushing 100W through a 4" lens at 2ipm, and you're putting a lot of energy in even 2" below the work
[18:25:55] <ssi> zeeshan: https://pbs.twimg.com/media/B0F0o0kCEAAX5XE.jpg:large it's been almost a year since I got the spindle in the vmc running
[18:29:34] <zeeshan> nice!
[18:29:41] <zeeshan> what vfd is thgat
[18:29:48] <ssi> zeeshan: 25hp hitachi
[18:29:58] <zeeshan> nice
[18:29:58] <ssi> wj200 I think?
[18:30:04] <sector_0> hey guys
[18:30:15] <XXCoder> ssi: is there such material that can eat any laser and desperse with energy so it dont cut but dont heat to fire either
[18:30:17] <ssi> zeeshan: did you see the spins video I put up yesterday?!
[18:30:41] <sector_0> I'm building a corexy machine for light milling
[18:30:47] <zeeshan> no
[18:30:49] <zeeshan> link?
[18:30:49] <sector_0> my machine looks something like this
[18:30:50] <sector_0> http://designwiththemajority.com/sites/default/files/inline-images/gantryFull.jpg
[18:30:50] <ssi> XXCoder: metal
[18:30:55] <ssi> zeeshan: https://www.youtube.com/watch?v=5glC4r38UPM
[18:31:10] <XXCoder> ssi: makes sense. up to a point I suppose?
[18:31:18] <XXCoder> can there be lasers that can cut metal?
[18:31:24] <sector_0> but the 2 y axis carriage unfortunately has a bit of slop so one moves a slight distance without the other
[18:31:27] <ssi> XXCoder: sure, but you can't afford them
[18:31:35] <XXCoder> for sure yeah
[18:31:43] <ssi> XXCoder: you need 1kw+ to cut metal
[18:31:45] <sector_0> I've decided to correct this problem by using a cross bar
[18:31:59] <sector_0> would epoxy be good enough to hold this in place?
[18:32:17] <XXCoder> I really need to get myself some 8020 or some extrusions
[18:32:29] <sector_0> the bonding surface is approximately 1 square inch
[18:32:30] <ssi> XXCoder: 8020 is expensive... I use a lot of the 20mm stuff
[18:32:34] <XXCoder> I need something to surround my cnc router in very least.
[18:32:50] <sector_0> ...one either side
[18:33:07] <DaViruz> an acquaintance has a mazak x48 for sale, that'll do up to 10mm carbon steel, fairly reasonably priced at $15k
[18:33:44] <sector_0> I'm planning on create 2 cross bars, one at that connects to the back of each carriage and one that connects at the front of each carriage
[18:33:47] <DaViruz> it eats nitrogen gas like crazy though, both for the laser resonance chamber and for cutting gas
[18:33:57] <ssi> DaViruz:that's a good price
[18:34:20] <DaViruz> he's upgraded to a machine that'll cut 20mm stainless
[18:34:21] <ssi> what's the power on his?
[18:34:24] <DaViruz> that's pretty crazy for laser
[18:34:25] <ssi> the one I'm looking at is 2500W
[18:34:27] <DaViruz> i'm not sure
[18:34:46] <ssi> is that all up, running, control and everything?
[18:34:54] <DaViruz> yeah
[18:34:59] <ssi> shit maybe I need to just get that heh
[18:35:01] <ssi> where is it?
[18:35:04] <DaViruz> sweden ;)
[18:35:07] <ssi> doh
[18:35:09] <Tom_itx> pfft
[18:35:14] <DaViruz> http://www.blocket.se/dalarna/Laserskarmaskin_Mazak_X_48_62805047.htm?ca=9&w=3
[18:35:51] <ssi> uhm
[18:35:55] <ssi> that says $125k
[18:35:58] <ssi> that sounds WAY more in line
[18:36:07] <DaViruz> swedish kronor yes
[18:36:12] <ssi> ohh
[18:36:14] <enleth> ssi: holy crap that wiring in the VMC ,_,
[18:36:15] <DaViruz> 9 of those to a dollar
[18:36:30] <ssi> about 19k
[18:36:40] <ssi> enleth: haha it's on its way OUT in that picture
[18:37:19] <enleth> I sure hope so
[18:37:20] <DaViruz> it's a beast of a machien though, id like to have it but i have nowhere to place it
[18:37:31] <ssi> yeah that's bigger than I'd like to have to deal with
[18:37:35] <ssi> BUT I'd make room for it at that price
[18:37:39] <DaViruz> ssi: but if you come and get it i'll give you a good deal on my vmc ;)
[18:37:41] <ssi> if it were anything like possible for me to move here heh
[18:38:11] <DaViruz> (that's equally unwieldy)
[18:40:20] <Contract_Pilot> Anyone want the path pilot torrent need seeds
[18:40:33] <ssi> sure
[18:41:51] <Contract_Pilot> just dcc me your e-mail i will send it.
[18:44:30] <Contract_Pilot> Torrent is slow.
[18:46:50] <ssi> I'm doing pretty well right now
[18:46:54] <ssi> especially with how horrible my internet is
[18:50:36] <Contract_Pilot> Need 2 mesa 7I76's like yesterday going to be a long 3 weeks
[18:51:26] <PetefromTn_> kinda surprised Mesa is that far behind on boards
[18:51:47] <Contract_Pilot> Yea, 4 weks behind as of monday
[18:52:17] <PetefromTn_> glad I got my 5i25/7i77 awhile back for the lathe
[18:52:20] <Contract_Pilot> and I am bad at saving machine funds for that long when i have it i like to spend it.
[18:52:53] <Contract_Pilot> they ahve the 7I77's
[18:53:09] <PetefromTn_> well there ya go man...GO SERVO!!
[18:53:14] <ssi> PetefromTn_: :D hahah
[18:53:24] <PetefromTn_> ;)
[18:53:32] <Contract_Pilot> Cannot afford servo and machine already has steppers
[18:53:58] <Contract_Pilot> Teady to rewire.
[18:53:59] <ssi> is this for the g0704?
[18:54:13] <Contract_Pilot> My 12X36 lathe
[18:54:16] <ssi> ah
[18:54:51] <PetefromTn_> I miss my 12x36 lathe
[18:54:58] <ssi> I miss your 12x36 lathe too
[18:55:02] <PetefromTn_> hehe
[18:55:06] <ssi> that was a nice machine
[18:55:08] <PetefromTn_> that was a nice little machine
[18:55:13] <PetefromTn_> LOL
[18:55:15] <ssi> I'm super super happy with my sb10 tho
[18:55:20] <ssi> that was a GOOD FIND
[18:55:38] <PetefromTn_> once my CNC lathe is running I will probably grab a good deal on manual lathe locally
[18:55:46] <ssi> yeah
[18:55:52] <ssi> it's nice to have a manual around
[18:56:40] <Contract_Pilot> Yea, i been working on this for a year now.
[18:57:12] <Contract_Pilot> never will go mach again
[18:57:18] <ssi> Contract_Pilot: don't feel bad... I started converting my g0704 in 2009 and it's still not done
[18:57:41] <Contract_Pilot> hahaha my 704 is just awaiting screws to be turned.
[18:57:42] <PetefromTn_> hehe Mach SUX
[18:57:49] <Contract_Pilot> worked on it a little last night.
[18:58:11] <ssi> yeah I bought mach for my first machine, the plasma cutter
[18:58:41] <ssi> at the time that was a decent setup because I bought a candcnc torch height control that had mach screens for it
[18:58:53] <ssi> that's the only mach machine I've ever run
[18:59:15] <ssi> I went linuxcnc for the next one
[18:59:39] <Contract_Pilot> may need 3 of the 7I76's hahaha
[18:59:57] <Contract_Pilot> Right now for sure 2
[19:00:06] <Contract_Pilot> once for the lathe one for the mill.
[19:00:30] <Contract_Pilot> Not sure i want to start in on the other 2 sherlines
[19:00:46] <Contract_Pilot> But 1 would work with both of them.
[19:00:46] * ssi considers selling his on-hand 7i76s for a substantial profit
[19:01:41] <ssi> samsung vr headsat for $99 ships november
[19:02:12] <ssi> Contract_Pilot: have you seen the GRT hud glasses?
[19:02:36] <Contract_Pilot> Nope
[19:02:39] <ssi> http://www.grtavionics.com/grtvision.html
[19:03:43] <Contract_Pilot> Cool but STC or TSO?
[19:03:49] <MacGalempsy> well damn, neither of the touchprobes I bought seem to work...
[19:03:57] <ssi> you wear it on your head so I don't imagine it needs to be either :D
[19:04:08] <MacGalempsy> I wonder if they had been crashed before I got them
[19:04:09] <ssi> but it integrates with their efises which are experimental
[19:04:17] <Contract_Pilot> Right
[19:04:30] <Contract_Pilot> or a field approval hahaha
[19:04:35] <ssi> yeah good luck
[19:04:59] <Contract_Pilot> What luck just have to kave a good inspector..
[19:05:15] <ssi> yeah, which I do, and I imagine you do too
[19:05:26] <ssi> but even then it'll be tough cause the inspectors have oversight, and that's a pretty big one
[19:05:35] <ssi> grt actually has a "ga approved" efis now
[19:05:45] <ssi> http://www.grtavionics.com/mini-ga.html
[19:05:59] <ssi> but the way it's approved is the way the mount works, it's considered a portable
[19:06:32] <ssi> but also, the way they do air data is probably going to be hard to do in a certified airplane legitimately
[19:06:39] <ssi> it would be easy to get away with, but it wouldn't be anything like legal
[19:07:38] <MacGalempsy> what do you guys think one of these things goes for? http://www.renishaw.com/en/am250-metal-additive-manufacturing-3d-printing-system--15253
[19:08:10] <ssi> god more than I could afford I'm sure
[19:08:50] <MacGalempsy> just says >$250,000
[19:08:52] <MacGalempsy> heh
[19:08:56] <ssi> hahah
[19:09:00] <MacGalempsy> if you got to ask....
[19:09:04] <ssi> yep
[19:09:23] <MacGalempsy> the quality in the brochure is pretty amazing
[19:10:20] <MacGalempsy> i just hope they still repair these models of touchprobes
[19:10:33] <Wolf_> big macs look good on the order board as well…
[19:11:18] <Wolf_> :) that does look cool tho
[19:12:04] <MacGalempsy> the video shows a giant gas chamber on the right
[19:13:21] <Wolf_> damn just the powder feed looks $$$$$$
[19:13:50] <MacGalempsy> looks like it fills a long hopper then dumps and spreads
[19:14:46] <Wolf_> yup
[19:15:14] <MacGalempsy> the rendering video is pretty sweet
[19:16:02] <Wolf_> 250 mm × 250 mm build area, up to 365 mm deep lol same as my 3d printer…
[19:16:32] <MacGalempsy> yeah, so there is vacuum chamber that purges atmospher and brings in argon
[19:17:13] <MacGalempsy> it is not that much different than the kickstarter one
[19:17:18] <MacGalempsy> just on steroids
[19:17:33] <Wolf_> http://www.renishaw.com/en/metal-powders-supply--31458
[19:17:52] <Wolf_> amazing part is what it can make stuff out of
[19:18:35] <Contract_Pilot> Posted wanted ad's on nearly every cnc group i could find.
[19:18:38] <MacGalempsy> it would be interesting to see some stress testing on the parts
[19:19:14] <MacGalempsy> think you could get linuxcnc to operate that thing?
[19:19:18] <Wolf_> I think spaceX uses inconel printed rocket nozzles
[19:19:27] <Contract_Pilot> I have a lot of stuff to barter also.
[19:19:39] <PetefromTn_> jeez wth is going on with my connection today LOL
[19:20:19] <Contract_Pilot> my daily bandwith sesets in abotu 4 min
[19:20:42] <Contract_Pilot> I can allow 4 direct downloads of path pilot.
[19:21:10] <MacGalempsy> Contract_Pilot: so tell me about set up in PathPilot
[19:21:29] <MacGalempsy> easier than PNCCONF?
[19:21:32] <Contract_Pilot> I have not set it up yet.
[19:21:43] <Wolf_> really someone just needs to unpack the setup, probably shed about a gig of un-needed files
[19:21:44] <Contract_Pilot> More involved
[19:22:06] <Contract_Pilot> Yea, somone will make it work.
[19:22:12] <MacGalempsy> can you program a turret with it easier than lcnc?
[19:22:39] <Contract_Pilot> Not sure have no way to play as i need mesa cards
[19:22:59] <Contract_Pilot> leave the programming to the pros
[19:23:03] <MacGalempsy> what platform does it run on?
[19:23:14] <Contract_Pilot> Would be cool to see a small package
[19:23:22] <Contract_Pilot> Linux
[19:23:37] <MacGalempsy> is it an iso?
[19:23:37] <Contract_Pilot> it is LinucCNC with a nice user innerface
[19:23:52] <MacGalempsy> i dont care about the interface, the hard part is the programming
[19:23:52] <Contract_Pilot> I made an ISO of it.
[19:25:03] <MacGalempsy> well, im off to watch a movie with the wifey. catch you all later
[19:28:51] <Sync> MacGalempsy: usually the electronics die in them
[20:09:08] <sector_0> I'm building a corexy machine for light milling
[20:09:13] <sector_0> my machine looks something like this
[20:09:17] <sector_0> http://designwiththemajority.com/sites/default/files/inline-images/gantryFull.jpg
[20:09:27] <sector_0> but the 2 y axis carriage unfortunately has a bit of slop so one moves a slight distance without the other
[20:09:34] <sector_0> I've decided to correct this problem by using a cross bar
[20:09:46] <sector_0> I'm planning on create 2 cross bars, one at that connects to the back of each carriage and one that connects at the front of each carriage
[20:10:06] <sector_0> would epoxy be good enough to hold this in place?
[20:10:11] <sector_0> the bonding surface is approximately 1 square inch
[20:10:14] <sector_0> ...one either side
[20:10:22] <sector_0> s/one/on
[20:12:14] <Praesmeodymium> I suspect the issue of getting an answer to this one is both people dont haveenough info on the forces nvolved and the epoxy in question, and even if all that info is in hand I think the answer is going to end up... let us know how it goes
[20:12:49] <sector_0> pfft
[20:13:01] <sector_0> my thoughts exactly
[20:13:26] <sector_0> I was hoping that I won't have to ruin my carriages with epoxy and then it doesn't work
[20:13:35] <Praesmeodymium> shapelock?
[20:14:46] <sector_0> Praesmeodymium, wish I had access to that
[20:15:36] <malcom2073> Yeah, it depends entirely on how much force, but I'd bolt it rather than using epoxy, since those cross bars are going to take the majority of the force when cutting near the edge
[20:15:37] <sector_0> I'll have to order it, which would take about the same time it takes for me to try out the epoxy and have the part machined again with a build in cross bar
[20:15:44] <Praesmeodymium> its pcl it comes under a couple names
[20:18:20] <sector_0> I'll have to check
[20:18:58] <sector_0> malcom2073, I would do that but the carriage is actually pretty small and I'll need at least 2 bolts to stop any kind of slop
[20:19:17] <malcom2073> sector_0: Lightweight is the bitter enemy of milling :P
[20:19:19] <sector_0> I'll have to check for the pcl
[20:19:48] <sector_0> malcom2073, well it's just for light milling, of soft plastic
[20:19:58] <sector_0> more engraving than anything else
[20:20:10] <sector_0> and 3d printing
[20:20:33] <malcom2073> Yeah you'd be ok with with engraving as long as you don't need super small detail
[20:20:55] <sector_0> malcom2073, what you mean?
[20:21:01] <sector_0> in terms of the slop I have?
[20:21:12] <malcom2073> sector_0: Not slop, flexability
[20:21:26] <sector_0> oh
[20:21:56] <malcom2073> Smooth rod is really flimsy, put a dial indicator on your axis, then push on it with a pound or two of force, see how much it moves
[20:22:18] <sector_0> oh ok
[20:22:31] <sector_0> will have to do that once I have the system setup
[20:23:43] <Praesmeodymium> reprap stuff is really not built with the rigidity of milling in mind. the average goal for reprap is cheap as fuck, if it prints ok then great if not I will print better parts for it till I get better prints lol
[20:24:23] <sector_0> at this point, just the thought of adding a cross bar seems hacked together, so I'm just gonna do something temporary until I can get the part machine with a built-in cross bar
[20:24:39] <malcom2073> Right, but even then, a cross bar will only help minimally
[20:25:13] <sector_0> malcom2073, really?
[20:25:14] <malcom2073> Even for engraving, unsupported smooth rod will likely not give you the results you want, but it'll be a good learning experience, and you'll still have a good printer at the end of it
[20:26:21] <sector_0> malcom2073, just so we're on the same page, my current concern is actually the slop between the 2 y axis carriages
[20:26:49] <malcom2073> Right, and a cross bar properly secured to the end carraiges will solve that particular problem
[20:27:22] <sector_0> malcom2073, but you're referring to the flex in the z axis?
[20:27:30] <malcom2073> No, the flex in both the X and Y
[20:27:42] <sector_0> ohhh
[20:28:30] <sector_0> yeah and my rods are 8mm smooth rods
[20:28:33] <sector_0> ...fuck
[20:28:35] <malcom2073> Heh wowza
[20:28:41] <malcom2073> yeah that's flimsy, I have a set of 8's on my 3d printer
[20:29:11] <malcom2073> Anything you do to strengthen it will make it better as a 3d printer as well, so you're not wasting your time
[20:29:32] <sector_0> well at least I have that going for me
[20:29:49] <sector_0> will have to rethink my CNC design
[20:30:06] <sector_0> what about does slide rails by THK?
[20:30:22] <sector_0> are they superior in any way to smooth rods?
[20:30:49] <sector_0> for example 12mm rods
[20:34:49] <Wolf_> lol
[20:36:19] <Wolf_> THK rail might be better then a 12mm rod...
[21:14:54] <Wolf_> fun, I think i can get this x block/stepper mount done in 2 pieces
[21:20:21] <Contract_Pilot> http://www.stevenrhine.com/wp-content/uploads/2015/09/Bulk-80s-1024x576.jpg
[21:21:49] <Contract_Pilot> My Interests What I am Looking for?
[21:21:49] <Contract_Pilot> 5C Collet Chuck D1-4 Mount (China Made OK)
[21:21:49] <Contract_Pilot> 5C Lever Type Collet Closer Must Fit MT5 Nose. (China Made OK)
[21:21:49] <Contract_Pilot> BXA lathe XL quick change tool holders (China Made OK)
[21:21:49] <Contract_Pilot> 2 Nema 34 Stepper Motors 600+ oz in
[21:21:49] <Contract_Pilot> Ar-15 Upper (PSA Quality Cheap)
[21:21:51] <Contract_Pilot> Mesa 1 5I25 2 Mesa 7I76 boards for CNC
[21:22:00] <Sync> pew pew
[21:22:38] <Contract_Pilot> Love to Barter!
[21:25:20] <Wolf_> love the random ar upper in the mid of cnc/tooling
[21:26:14] <Contract_Pilot> hahahaha.
[21:26:27] <malcom2073> Ooohhh I saw you on facebook Contract_Pilot
[21:26:30] <t12> i just got a 4jaw
[21:26:33] <t12> i wonder how this will work out
[21:26:36] <Contract_Pilot> Yep.
[21:26:40] <malcom2073> I thought you were SELLING the mesa boards :-P Was about to ask how much then I realized you wanted to buy :P
[21:26:54] <Wolf_> I need a bigger lathe so I can put my AR on a diet
[21:27:29] <malcom2073> Wolf_: How big of a spindle hole do you need for that?
[21:27:44] <Wolf_> non, between centers
[21:28:17] <malcom2073> Ohhh, how big?
[21:28:34] <Wolf_> iirc the barrel is 1.25” under the hand guard, little over 16”
[21:28:46] <malcom2073> Buy my southbend :P
[21:28:53] <Wolf_> lol
[21:29:12] <Wolf_> if it had a gearbox for threading I would...
[21:29:15] <Wolf_> :P
[21:29:35] <malcom2073> Heh, it has a full changegear set
[21:29:44] <Contract_Pilot> Cat checking quality control. http://airplanemanuals.com/ak-kits/Cat%20Inspecting%20Mags.jpg
[21:29:51] <Tom_itx> what's the low thread on it?
[21:30:02] <Tom_itx> my buds will do 3 tpi
[21:30:09] <Tom_itx> most don't go that low
[21:30:24] <malcom2073> Unknown, whatever the 12 gear set for southbends gives ya :P
[21:30:45] <Wolf_> I know my 7x10 won’t do 5tpi, I think I busted a gear trying it
[21:34:27] <Tom_itx> http://tom-itx.no-ip.biz:81/~webpage/temp/thread1.jpg
[21:34:30] <Tom_itx> 3 TPI
[21:38:21] <Praesmeodymium> the combination of cat and pilot made me think of this http://www.today.com/video/watch-stowaway-cat-clings-to-the-wing-of-ultralight-aircraft-469814339726
[21:38:58] <Praesmeodymium> I would never ride with said pilot again because in my non understanding world he obviuosly did not inspect the aircraft carefully before take off
[21:40:26] <Sync> well, a cat is quick to hop on
[21:40:50] <Praesmeodymium> on another note... damn prepping for the zombipacolypse?
[21:43:20] <malcom2073> Murca
[21:43:33] <Contract_Pilot> Seen that one
[21:43:48] <Contract_Pilot> Bad preflight
[21:43:51] <jdh> I don't understand the attraction to 80%, but... how much for one?
[21:44:14] <Contract_Pilot> The attraction is they do not exist!
[21:44:26] <jdh> nothing has to exist
[21:44:54] <Contract_Pilot> Expecially in states where a BG check is required
[21:45:00] <jdh> oh.
[21:45:31] <jdh> I can buy anything (normal) I want from any random stranger, it effectively doesn't exist at that point.
[21:45:32] <Contract_Pilot> No gov does not need to know how many firearms i have hahaha
[21:45:43] <Contract_Pilot> Right.
[21:45:53] <malcom2073> jdh: They're about $70 iirc, I bought a couple like a year or two ago
[21:46:02] <Contract_Pilot> 60.00
[21:46:07] <jdh> or a complete psa blem for $35
[21:46:22] <Contract_Pilot> + Ship + FFL
[21:46:44] <malcom2073> Ah I misunderstood what he was asking, sorry heh
[21:47:33] <Contract_Pilot> I am in to them for what i am in to them for they sell good here since we passed a BG Check law.
[21:47:47] <Contract_Pilot> + People like to make things
[21:48:16] <Contract_Pilot> 7075-T6 Broached Mag Well.
[21:48:48] <Contract_Pilot> But right now they are trading stock.
[21:48:49] <jdh> so you sell to people who can't pass a bg check?
[21:49:01] <Contract_Pilot> It is just a hunk of metal.
[21:49:12] <t12> yeah the main attraction is no-list
[21:49:22] <t12> though i'm sure you end up on some other list really
[21:49:42] <malcom2073> Most people who buy stuff aren't the people who can't pass a BG check, they're the people who don't *want* to have to
[21:49:49] <t12> stolen/black market is likely the most practical no-list way
[21:50:02] <malcom2073> The kind of people who can't pass a BG check typically don't buy legit anyway
[21:50:21] <Contract_Pilot> I can pass a BG Check no problem prefer not to do one so i build...
[21:50:32] <t12> my grandfather was an early anti-gov prepper
[21:50:42] <t12> while simultaniously being a .mil contract negotiator
[21:51:05] <t12> he was convinced the gov was going to do suppression and disarm of population in response to the 60s
[21:51:11] <malcom2073> Heh
[21:51:19] <Contract_Pilot> Stolen markey can = the clink if you get caught with it! if you build it no possesson of stolen firearm
[21:51:24] <t12> so he stockpiled arms
[21:51:26] <malcom2073> That reminds me, isn't the world supposed to end again soon?
[21:51:32] <t12> the world is over!
[21:51:59] <t12> dont get caught with it!
[21:54:03] <jdh> do they anodize them?
[21:55:31] <Tom_itx> malcom2073, it ended already
[21:55:40] <malcom2073> I missed the blood moon?
[21:56:02] <Tom_itx> this isn't reality
[21:56:04] <Tom_itx> it's all a dream
[22:25:45] <Wolf_> well, this should be almost simple to make http://i.imgur.com/fzcaAfq.png?1
[22:41:37] <Contract_Pilot> I give up for the night!
[23:37:24] <PetefromTn_> getting the last of the recent orders finished tonight. Also anodizing a few at the same time.
[23:37:39] <PetefromTn_> Got a BUNCH of Steel plate to machine next week if all goes well.
[23:51:32] * furrywolf flops over completely exhausted
[23:54:56] <furrywolf> good news is UPS finally found my new wobblelight... yay. now I have a new one, that will be nicer than my other two well-used ones that are held together with lots of jbweld. :)
