[00:00:02] <Valen> CASA here is all over everything :-<
[00:00:18] <SpeedEvil> It doesn't say anythin about a pilot, because you can't lift an adult pilot and keep to the unmanned category.
[00:00:38] <SpeedEvil> But - a self-upgrading craft that winches a pilot up later is now possible
[00:00:59] <ssi> possible perhaps
[00:01:01] <Valen> why not just have them all assemble in the air then have the pilot grab on
[00:01:01] <ssi> but feasible?
[00:01:09] <SpeedEvil> Valen: that works too
[00:01:39] <SpeedEvil> ssi: the other loophole in the regs is if you strap on a parachute, and then grab hold of tethers to 10 or so RC aircraft and drag yourself into the air.
[00:01:50] <furrywolf> ssi: here's your bigger robot: https://www.youtube.com/watch?v=YzaXMzYFtSM
[00:01:56] <SpeedEvil> Parachutes have the same 'none of the other regulations apply'
[00:02:11] <Valen> and a powered parachute?
[00:02:23] <ssi> or parasailing
[00:02:26] <ssi> all sorts of things like that
[00:02:30] <ssi> again, in the US they mostly don't care
[00:02:33] <SpeedEvil> Powered parachutes are under different regs because they have permentantly attached engines.
[00:02:37] <ssi> so long as you don't endanger other air traffic
[00:03:09] <ssi> furrywolf: that's a good start!
[00:04:23] <Valen> this one is good for spitfire noises https://www.youtube.com/watch?v=cUkAwQkdynA
[00:04:34] <Valen> you can hear the supercharger ;->
[00:05:02] <furrywolf> ssi: all you need to do is convert it to wood gas and tweak the AI a bit...
[00:05:07] <ssi> yusss
[00:06:31] <ssi> Valen: to answer your question
[00:06:43] <ssi> I think the best way for you to launch your D-21 sized ramjet
[00:06:58] <ssi> is to strap it on your blackbird-sized blackbird that you're gonna build along side it :D
[00:07:03] <Valen> hah
[00:07:11] <Valen> that is historically a very very bad idea
[00:07:14] <ssi> :D
[00:07:26] <Valen> even I'm not insane enough to think supersonic seperations are a good plan ;->
[00:07:29] <furrywolf> ssi: https://www.youtube.com/watch?v=dfqYCbcQcpY is the wheeled version... watch how quickly it processes a tree.
[00:07:54] <ssi> holy crap
[00:08:12] <SpeedEvil> Supersonic seperations aren't bad as long as Q=~0
[00:08:31] <Valen> what are you defining Q as there?
[00:08:35] <ssi> dynamic pressure
[00:08:49] <ssi> Q=~0 is the definition of space :)
[00:09:01] <Valen> ahh, at the point where "supersonic" gets "air" quotes ;->
[00:09:14] <SpeedEvil> If you're up where yes, there are supersonic shocks, but they have ~1PSI force, it's lots easier
[00:09:16] <ssi> yeah as Q goes to 0, the speed of sound goes to infinity :)
[00:09:24] <SpeedEvil> It doesn't
[00:09:29] <SpeedEvil> It stays at ~mach 1
[00:09:29] <ssi> or is it the other way around
[00:09:34] <furrywolf> ssi: I'm quite sure your forest-destroying robot made out of one of these can harvest fuel much faster than it can burn it. :P
[00:09:50] <ssi> mach 1 isn't a fixed speed
[00:09:56] <ssi> it's variable with altitude
[00:10:00] <Valen> it wobbles as you go up, but I believe it goes back down when you get really high
[00:10:01] <ssi> ie density
[00:10:02] <ssi> ie Q
[00:10:13] <ssi> furrywolf: I'm sure it can!
[00:10:30] <furrywolf> you could use the much-easier-to-find wheeled version, but the walking one is probably required for building an evil robot.
[00:10:33] <Valen> http://en.wikipedia.org/wiki/Speed_of_sound#mediaviewer/File:Comparison_US_standard_atmosphere_1962.svg
[00:11:21] <ssi> ah well
[00:11:33] <ssi> much like I don't think beyond mach 1, I also don't think much beyond FL600
[00:11:35] <ssi> :)
[00:11:47] * Valen has a degree in space science
[00:11:53] * Valen is itching to use it in anger lol
[00:12:00] <ssi> go play kerbal space program :D
[00:12:00] <furrywolf> lol
[00:12:06] <Valen> I totally do
[00:12:10] <ssi> it's so much fun
[00:12:24] <ssi> http://xkcd.com/1356/
[00:12:26] <Valen> then get shitty at it for being single threaded and having crap connections
[00:12:40] <ssi> I get mad because my stations always make the physics engine go to shit
[00:12:42] <Valen> also that graph is totally accurate
[00:12:45] <ssi> yep!
[00:12:52] * furrywolf has never liked games
[00:13:03] <Valen> KSP isn't a game
[00:13:10] <ssi> ksp is a game the way flight simulator is a game
[00:14:07] <furrywolf> yes
[00:14:39] <ssi> I'm gonna stay home from work tomorrow and hopefully go fly the RV6 a bunch more
[00:14:51] <ssi> I'm trying to get 30 hours in it before they sell it
[00:14:58] <ssi> it'll DRASTICALLY help with my insurance when I get mine finished
[00:15:02] <ssi> I'm at 9 hours thus far
[00:15:21] <Valen> ssi: My other reason for wanting the D-21 is it turns out I get quite airsick ;->
[00:15:25] <ssi> https://pbs.twimg.com/media/B9gMdjZIQAAlRQ0.jpg:large
[00:15:31] <Valen> so less time in the air seems like a good thing ;->
[00:15:33] <ssi> hah
[00:15:50] <ssi> a lot of people who get airsick have fewer issues with it if they're handling the controls
[00:15:56] <ssi> I get airsick in some conditions if I'm not flying
[00:15:58] <Valen> you say that.....
[00:16:03] <furrywolf> bbl, time for bed.
[00:16:07] <Valen> first flight, lunch inspection ;->
[00:16:17] * ssi makes a note to not take Valen flying
[00:16:18] <Valen> also I recently discovered helicopters are the devils work
[00:16:25] <ssi> haha how so
[00:16:29] <Valen> they wobble
[00:16:34] <ssi> yes, by design :D
[00:16:35] <Valen> in a totally unsettling way
[00:16:44] <ssi> ten thousand parts spinning rapidly around an oil leak
[00:17:10] <ssi> btw the reason that RV has a pink cowl
[00:17:15] <ssi> is because it used to have a GODFORSAKEN SUBARU ON IT
[00:17:16] <Valen> that aside, its just freaky how wobbly the ride is
[00:17:17] <ssi> :D
[00:17:29] <Valen> i mean you can feel trees from 500ft
[00:17:40] <ssi> I don't have any significant time in rotorcraft sadly
[00:17:44] <ssi> I would really like to get my rotorwing addon
[00:17:53] <ssi> but they're horribly expensive
[00:18:05] <Valen> also as a fellow husky gentleman you will need to go up a size in heli
[00:18:09] <ssi> my most significant time in rotorcraft was the lifeflight ride I got when I crashed my motorcycle :P
[00:18:14] <ssi> yeah I know
[00:18:19] <ssi> R22 has a seat weight of 235lb I think
[00:18:25] <Valen> the small ones have a max pasenger weight of like 90kgs
[00:18:26] <ssi> and the cost goes up exponenitally with size
[00:18:28] <Valen> something like that
[00:18:55] <ssi> aircraft in general are very unforgiving to the oversize or overweight :(
[00:19:17] <ssi> I want to build one of these really bad:
[00:19:18] <ssi> http://en.wikipedia.org/wiki/Eagle_Helicycle
[00:19:21] <Valen> I don't have as much of an issue on commercial flights
[00:19:23] <ssi> but I'd have to lose some ass for that too
[00:19:30] <furrywolf> they're especially unforgiving if you have to sit next to one of them in economy. :P
[00:19:34] <Valen> still not chipper but not too bad
[00:19:52] <ssi> economy is roomy compared to some experimental planes :P
[00:20:13] <ssi> the pitts I'm building is CG sensitive
[00:20:19] <ssi> I need to drop another 20lb or so to get it in limits
[00:20:29] <furrywolf> bbl
[00:20:33] * Valen wagers ssi like himself fits fine into an economy seat
[00:20:35] <ssi> good motivation at least
[00:20:42] <ssi> yeah I fit fine in an economy seat
[00:20:59] <ssi> my only problem there is I have screwed up knees from teh aforementioned motorcycle wreck, and they don't like to be penned in for long flights
[00:21:23] <Valen> its scary when you see the pictures of the people they make buy 2 seats and think, they don't weigh that much more than me....
[00:21:29] <ssi> when I was a kid I went for the window seat... nowadays I go for the aisle so I can stretch out as much as possible
[00:21:33] <Valen> but they are like 4x the size
[00:21:40] <ssi> Valen: yea I dunno about you but I'm dense
[00:21:43] <PetefromTn_andro> Well I got some freaking kerosene and a few gallons of milk just in case the sky falls heh
[00:21:47] <ssi> I'm relatively normal sized, but heavy :/
[00:21:50] <Valen> evidently I'm the same ;->
[00:21:52] <Valen> so is wifey
[00:21:57] <ssi> sucks
[00:22:10] <Valen> I'd rather be dense than super jumbo sized lol
[00:22:16] <ssi> yeah me too
[00:23:54] <ssi> but also I'm thankful I'm not terribly tall
[00:24:07] <ssi> I'm 5'11", which isn't short exactly, but not tall
[00:24:11] <ssi> and that RV6 is short for me
[00:24:20] <ssi> I have to run without the seat back in or my head touches the canopy without a headset on
[00:24:25] <ssi> anyone taller than me just can't fly it
[00:24:47] <Valen> 5'10" here
[00:25:13] <ssi> and mass?
[00:25:31] <Valen> hah crap thats a lot of pounds
[00:25:37] <Valen> 279lbs give or take
[00:25:43] <ssi> I'm about 125kg, and that's down 10kg in the last couple months
[00:25:48] <ssi> haha I like it in your units a lot better :)
[00:25:53] <PetefromTn_andro> They sure have the roads prepared here already for the ice that is apparently supposed to come tonight
[00:25:53] <Valen> lol same
[00:26:19] <ssi> need to be at 115kg to make the pitts balance
[00:26:28] <ssi> shit I might start embracing the metric system for that reason alone
[00:26:39] <Valen> I've probably gone up a bit, waiting for the gym to have their super discounts again
[00:26:58] <ssi> my roommate is 6'2" and 345lb
[00:27:04] <ssi> he's gained 60lb since I've known him
[00:27:10] <ssi> he's a pilot too :/
[00:27:55] <ssi> I've been seriously considering taking up crystal meth
[00:28:07] <ssi> I hear it's great for weight loss
[00:28:17] <Valen> its weird when you see the commando type though isn't it and you feel about 2ft high
[00:28:18] <ssi> and I've never been particularly attache dto my teeth
[00:28:28] <Valen> file that under plan-B huh?
[00:28:33] <ssi> yep
[00:28:34] <Valen> take a look at the fasting diet
[00:29:00] <Valen> worked super well for me, not so good for the missus
[00:29:03] <ssi> hm
[00:29:19] <Valen> basically 2 days a week you eat ~500 calories of "good" foods
[00:29:32] <Valen> then the rest of the time whatever
[00:30:12] <Valen> does lots of good things for insulin resistance and all sorts of other stuff
[00:30:23] <Valen> you learn the difference between hungry and thirsty
[00:30:28] <ssi> yeah
[00:30:33] <ssi> haha I heard a good quote recently
[00:30:41] <ssi> "If you're not hungry enough to eat broccoli, you're not hungry"
[00:30:59] <Valen> and its not a "starvation" diet or anything silly like that, so you don't have thyroid problems
[00:31:10] <ssi> might actually work well for me
[00:31:14] <ssi> I tend to forget to eat pretty often
[00:31:18] <ssi> friday I had one meal
[00:31:28] <ssi> today I had one and a half thus far
[00:31:49] <Valen> I think thats why it works, not eating for a little is easier than eating "the right amount all the damn time"
[00:32:54] <ssi> I think I've eaten approx 1500 cal today
[00:33:01] <ssi> and I'm currently hungry
[00:33:02] <Valen> it also is great for losing fat because during the fasting you have to burn it off, you don't have dietary calories to use instead. Then on your regular days you aren't in "starvation mode" from prolonged reduction in calories so you don't pile it back on
[00:33:04] <ssi> but I waited too long to eat
[00:33:04] <ssi> heh
[00:33:14] <Valen> the recipies are good for it too
[00:33:36] <Valen> meaty breakfast of smoked salmon and mushrooms, or fish and onion
[00:33:55] <Valen> then I have a huge bowl of beans, tomato and tuna for dinner
[00:34:08] <Valen> and an assload of coriander
[00:34:24] <Valen> turns out beans are low in calories, who knew?
[00:34:37] <ssi> I could go for that right now
[00:34:51] <Valen> lol same ;->
[00:35:02] <ssi> I'm guessing you mean coriander leaf, not seed?
[00:35:06] <Valen> yeah
[00:35:11] <ssi> cause an assload of coriander seed doesn't sound appetizing
[00:35:21] <ssi> we'd just call it cilantro in leaf form :D
[00:35:24] <ssi> and I loooove it
[00:36:10] <ssi> dammit now I'm hungrier than I was
[00:36:15] <ssi> and it's well past time to go home
[00:36:16] <Valen> lol
[00:36:25] <Valen> I have to go pickup the wifey
[00:36:35] <ssi> do that; it's 1:15am and I'm at work
[00:36:37] <ssi> going the hell home
[00:36:38] <ssi> ttyl :)
[00:36:56] <Valen> also called 5/2 diet if you are googling
[01:39:42] <XXCoder1> holy hell piercing probes is so expensive'
[01:41:28] <XXCoder1> its expensive even at aliexpress
[02:21:51] <Deejay> moin
[02:25:44] <witnit> mojn
[02:28:02] <witnit> those threadless ballscrews are sweet
[02:31:42] <SpeedEvil> ?
[02:32:52] <witnit> oh, this guy over at reprap showed me them, simple, functional
[02:32:55] <witnit> https://www.youtube.com/watch?v=NA_9GeFxV0o
[02:33:32] <XXCoder1> any of you know cheap source of percing multimeter probes?
[02:34:07] <SpeedEvil> sharpen normal ones
[02:34:16] <XXCoder1> it wont hold on on its owb
[02:34:23] <XXCoder1> and mine is extremely sharp
[02:36:33] <SpeedEvil> http://www.ebay.co.uk/itm/Pair-of-Insulation-Piercing-HQ-Test-Probes-FANTASTIC-IP-Professional-Pro-Meter-/140904447169?_trksid=p2141725.m3641.l6368
[02:36:42] <witnit> XXCoder1, we should be producing these things
[02:36:58] <XXCoder1> expensive.
[02:41:26] <SpeedEvil> witnit: 20 thou drift isn't great
[02:42:41] <witnit> yeah but the cost of it, im sure some applications it would be fine
[02:43:37] <archivist_herron> drift will vary with load too
[02:44:01] <witnit> if you could put a magnetic encoder in the core of the rod
[02:44:07] <witnit> would it matter then?
[02:45:29] <SpeedEvil> that's going to be tricky.
[02:45:32] <archivist_herron> we used to get drive slip like that pulling paper through printers,
[02:45:36] <SpeedEvil> It's probably easier to add an encoder
[02:45:45] <SpeedEvil> Also- imagine a grease spot
[02:45:59] <archivist_herron> and wear
[02:46:05] <witnit> yeah but cost
[02:46:08] <witnit> to replace
[02:46:50] <witnit> if this were a laser etching machine
[02:46:56] <archivist_herron> flat spots on the balls
[02:47:00] <witnit> who cares about those things
[02:47:21] <witnit> im sure there are some ideas in this
[02:47:30] <archivist_herron> those that care about accuracy and repeatability
[02:48:03] <witnit> thats not always the goal luckily
[02:50:18] <witnit> it looks like an extremely useful device where you want slippage under excess loads
[02:53:53] <SpeedEvil> I suspect you'll get better results with oiled allthread
[02:54:23] <SpeedEvil> And standard nuts, adjusted to approximate a zero backlash nut
[02:54:59] <SpeedEvil> I keep meaning to test oiled allthread
[02:55:21] <witnit> for what?
[02:55:38] <SpeedEvil> Life.
[02:55:55] <witnit> im guessing allthread is made of 1020
[02:56:08] <SpeedEvil> Well - there are various sorts
[02:56:14] <SpeedEvil> there is 8/8 allthread
[02:56:24] <SpeedEvil> stainless rolled, lots of variants.
[02:56:33] <SpeedEvil> you probably want to steer away from hot-dip galvanised :)
[02:57:01] <witnit> you wil just buy allthread and a halfnut?
[02:58:18] <SpeedEvil> Make out of two ordinary nuts
[02:59:42] <SpeedEvil> I'm quite aware this would not be ideal. Good enough - well...
[03:00:30] <Jymmm> you need to spring load the nuts oposing each other
[03:00:31] <witnit> just think, you could go buy a fetti head and roll yourself a mile of axis
[03:00:34] <SpeedEvil> And yes.
[03:00:53] <witnit> brilliant,
[03:01:01] <SpeedEvil> I know in principle why it's going to be crap.
[03:01:12] <SpeedEvil> I don't know in terms of actual numbers how crap.
[03:03:04] <witnit> what kind of load is it?
[03:03:52] <archivist_herron> I used a bit for the leadscrew on my hobbing machine but that axis has little need for accuracy when cutting spur gears
[03:06:04] <SpeedEvil> witnit: Well - my canonical project idea is ~100kg or so maximum force on teh axis - 2.4*1.2m router table.
[03:06:46] <SpeedEvil> And on the accuracy front - why would I care about accuracy when I can trivially store corrections per .5mm of axis.
[03:06:51] <SpeedEvil> (I know there are issues)
[03:14:22] <witnit> 80/20 ?
[03:23:17] <witnit> http://www.ebay.com/itm/Industrial-Heavy-Duty-Erector-Set-Prototype-Machine-Robotic-Framing-123-Block-/200987615369?pt=LH_DefaultDomain_0&hash=item2ecbcba089
[03:23:23] <witnit> sooo awesome
[03:23:38] <witnit> play all day
[04:08:38] <SpeedEvil> that does look like fun
[05:45:33] <jthornton> now they say snow for the next 2 days
[06:17:19] <jthornton> logger[mah] log
[07:03:05] <Tom_itx> ~2" here so far, jthornton looks like you're getting the most of it
[07:05:51] <jthornton> yea, it's 3-4" and snowing hard
[07:27:46] <jthornton> make that 6-8"
[07:29:57] * Loetmichel just has mounted a chinese universal DVI->lvds board to a "vga only" Dell monitor... took a LOT of tinkering and solderning...and some signals had to be inverted... now it runs... *DINNER* ;-) (only 2 hrs late) and then i will have to do 22 of them... :-(
[07:56:00] <JT-Shop> fluffy snow too
[08:00:16] <jdh> buy new monitors
[08:02:34] * JT-Shop finally found a SW model of a Kossel
[08:06:34] <jdh> cool
[08:06:41] <jdh> whatd a kossel
[08:07:54] <Loetmichel> jdh: no option. boss has sold 22 new dell moniotrs to a customer... "yes, sure this specific model has Dvi in"... it hasnt...
[08:09:51] <SpeedEvil> Loetmichel: ...
[08:09:54] <SpeedEvil> Insane
[08:10:37] <Loetmichel> SpeedEvil: just a normal day here ;-)
[08:11:02] <SpeedEvil> At least it's fun.
[08:11:22] <JT-Shop> oh this is a bit bigger one with 420mm horizontals and 1,000mm vertical beams
[08:17:23] * JT-Shop suits up like Ralphie's little brother Randy to go shovel snow
[08:18:50] <jdh> I would not buy anything from you again.
[08:30:49] <Loetmichel> SpeedEvil: doesent look So well, have to do some more adapter boards to get rid of the wire knot, but it works: http://www.cyrom.org/palbum/main.php?g2_itemId=15657
[08:31:49] <JT-Shop> you who?
[08:33:41] * JT-Shop gets to assembling the dual fills
[08:35:12] <jdh> I applaud your ingenuity. but, that is just way too half assed for commercial work
[08:35:40] <SpeedEvil> yeah
[08:35:44] <SpeedEvil> needs more hot-glue
[09:08:33] <tjtr33> nasa tech briefs announced webinar on additive tech for 'concrete buildings in a day' http://www.techbriefs.tv/video/Contour-Crafting-Revolutionary; sign up soon if interested.
[09:10:11] <JT-Shop> snowing about 1" per hour
[09:10:22] <skunkworks> yikes
[09:11:23] <JT-Shop> not quite a white out but close
[09:14:49] <JT-Shop> skunkworks, you see my all metal Kossel design?
[09:17:31] <skunkworks> JT-Shop, no? what?
[09:18:03] <JT-Shop> http://gnipsel.com/images/3-D%20Printing/JT%20Kossel/
[09:18:28] <JT-Shop> delta with no printed parts for guys like me that don't have a 3-d printer
[09:18:42] <miss0r> I asked in here the other day, how to determin the speed of a stepper motor. i.e. how fast I can make it rotate, I got a link from someone, and i've lost it - and apparently I do not log my irc chat. help please :D
[09:20:35] <JT-Shop> how fast depends on the voltage and the driver and how fast you can make step pulses
[09:20:45] <JT-Shop> what size stepper?
[09:22:26] <miss0r> nema23 was the plan
[09:24:27] <skunkworks> JT-Shop, cool!
[09:25:00] <miss0r> brb
[09:25:05] <JT-Shop> miss0r, go to automationdirect.com and look at the spec sheets for steppers
[09:25:12] <JT-Shop> skunkworks, thanks
[09:26:02] <skunkworks> on the mk side someone is trying to make an auto-calibrator for the delta style printer
[09:26:56] <JT-Shop> I see auto calibrators on several of the kossel designs, but I'm not sure how that works
[09:29:29] <JT-Shop> my main interest is in lost PLA casting http://gnipsel.com/images/casting/
[09:30:38] <CaptHindsight> JT-Shop: SLA is much faster and higher res
[09:31:03] <CaptHindsight> if you need that
[09:31:41] <JT-Shop> what is SLA?
[09:32:30] <CaptHindsight> well SLA with DLP or LCD, you use a photopolymer with a laser+galvo (slowest) or DLP/LCD projector
[09:33:04] <JT-Shop> got a link to that?
[09:33:34] <CaptHindsight> https://www.youtube.com/watch?v=ygHVVKkJWlI video
[09:34:56] <CaptHindsight> https://www.youtube.com/watch?v=eKk2vRysioE this is SLA but using a projector like DLP/LCD prints a layer at a time vs just a point
[09:36:00] <ssi> morn
[09:36:30] <JT-Shop> not DIY I think
[09:36:49] <CaptHindsight> it's easy DIY
[09:37:00] <CaptHindsight> you just have a Z axis for motion
[09:38:26] <CaptHindsight> project the image 1 second, move the Z down below the surface of the resin, and then back up minus the layer thickness, project the next layer, repeat
[09:39:47] <CaptHindsight> the g-code is really simple
[09:39:50] <JT-Shop> got a DIY link?
[09:40:11] <JT-Shop> brb, gotta shovel more snow
[09:45:36] <SpeedEvil> JT-Shop: with g-code?
[09:45:41] <SpeedEvil> And if not - why not
[09:50:55] <JT-Shop> don't ask me I'm still trying to figure out what CaptHindsight is talking about
[09:52:55] <CaptHindsight> JT-Shop: here is one version http://code.google.com/p/lemoncurry/wiki/main but I'd suggest using the top projection to the surface of the resin vs up through the bottom of a vat
[09:56:49] <SpeedEvil> JT-Shop: I meant for the snow :)
[09:57:04] <JT-Shop> lol
[09:57:06] <CaptHindsight> JT-Shop: https://www.youtube.com/watch?v=8ehlWYfdS70
[09:57:08] <JT-Shop> I wish
[09:57:28] <CaptHindsight> JT-Shop: http://education.mrsec.wisc.edu/309.htm
[09:58:33] <SpeedEvil> I inadvertantly found the power of compressed air to dig
[09:58:49] <SpeedEvil> Blew a 4" crater in my compacted gravel path
[09:59:02] <SpeedEvil> And managed to lose the little drain valve of my compressor :/
[09:59:48] <JT-Shop> I had a blow out once on the back hoe and man that made a hole in the driveway when it blew
[10:02:46] <CaptHindsight> JT-Shop: https://www.youtube.com/watch?v=Ly4bbGY2-pI
[10:03:32] <CaptHindsight> https://www.youtube.com/watch?v=L-eSRdxjvD8
[10:11:23] <JT-Shop> looks like he is printing in a dish tub
[10:12:46] <CaptHindsight> low budget resin tank
[10:14:42] <JT-Shop> what makes the image?
[10:23:05] <CaptHindsight> JT-Shop: there is software that slices STL's and makes a stack of SVG's for the projector
[10:24:23] <JT-Shop> that makes sense to me
[10:24:43] <tjtr33> i see the wiper, and i read about 12um vertical steps. is there some 'nearly solidified' area above the 'really solidified' area that is aided by the wiping?
[10:25:01] * JT-Shop noticed the snow has stopped and neither tractor has the correct implement on it to grade the driveway
[10:25:16] <CaptHindsight> the wiping is for dealing with the surface tension of the resin
[10:25:59] <CaptHindsight> tjtr33: ever fill a glass to just over the rim?
[10:26:03] <tjtr33> ah, the wiping is not at the top of the part, its a skin thing at tank volume surface
[10:26:08] <tjtr33> menscus?
[10:26:32] <CaptHindsight> the wiping breaks the surface tension
[10:26:43] <tjtr33> add a drop of soap :)
[10:27:09] <CaptHindsight> it's a bit more complicated than that
[10:27:15] <tjtr33> very interesting videos, esp #1 from MrSec
[10:27:47] <tjtr33> joke @ soap ^^^
[10:29:00] <CaptHindsight> well surfactants are used in inkjet inks
[10:33:31] <CaptHindsight> if you're using a very high viscosity resin say 1K cps, like warm honey, it takes a while for the vat to settle, the wiper speeds that up
[10:37:57] <tjtr33> ah, i didnt see that part, leveling the mound, likely irregular over surface of part vs empty tank.
[10:38:13] <JT-Shop> how expensive is the projector?
[10:40:14] <tjtr33> JT-Shop, i got mine from a school district upgrading theirs, newish epson for 100$. brand new off shelf can be >1K$, but lotsa people updgrading their smancy home theatres
[10:41:02] <tjtr33> i use it to watch movies on garage door in summer ;) have not done DLP yet
[10:42:12] <JT-Shop> yea 1k would be a bit tough to chew
[10:42:35] <CaptHindsight> I've gotten many on ebay for <$100
[10:43:05] <JT-Shop> so you have built them?
[10:43:21] <CaptHindsight> if you modify the projector to use an $10 LED vs lamp you can get projectors for next to nothing
[10:45:30] <tjtr33> yeah its the bulb that has limited remaining life that gets you on the used units. like buying a car with no odometer
[10:46:01] <CaptHindsight> the lamps are $100-250ea and they are very inefficient
[10:46:18] <CaptHindsight> been using LED for the past few years
[10:46:30] <tjtr33> btw newegg has a few 2500lumes for 300$ new
[10:47:18] <XXCoder1> CaptHindsight: what kind of led lamp
[10:47:19] <CaptHindsight> a 10W LED is <$10 now in the 405nm or 450nm range
[10:47:34] <XXCoder1> always wanted good projector. I use eyeclops for now lol
[10:47:56] <CaptHindsight> I think we pay $35 for the 100W leds
[10:48:04] <tjtr33> cool, an led bulb hack for my epson http://hackaday.com/2013/03/28/epson-projector-led-mod/
[10:48:11] <XXCoder1> chwap here, just $15
[10:48:25] <XXCoder1> special goverment deal, they pay for half led
[10:48:43] <XXCoder1> my room is led lit
[10:48:49] <XXCoder1> so are my alarm clock
[10:48:52] <CaptHindsight> http://www.ebay.com/itm/like/231176603288
[10:49:30] <XXCoder1> hmm uv? isnt that uselss for projector?
[10:49:36] <tjtr33> thx CaptHindsight (didja see the NASA concrete printer webinar ^^^ wed 10am est ) off to drywall! bbl
[10:50:53] <CaptHindsight> XXCoder1: >390nm work fine in the projectors, >400nm for the ones with UV coatings, 450nm is the Blue used in the LED RGB projectors
[10:51:16] <XXCoder1> interesting
[10:51:30] <XXCoder1> so end result would be fine?
[10:53:01] <CaptHindsight> and it also depends on the resin, I make them for UV as well as up to Blue/Green, well really up to IR
[10:53:54] <XXCoder1> cool
[10:54:41] <CaptHindsight> JT-Shop: an HD (1920 x 1080) projector gets you 0.004" XY res at 7.5" x 4"
[10:55:42] <CaptHindsight> 0.002" XY 3.25" x 2"
[10:56:18] <XXCoder1> eyeclops is fun projector lol
[10:56:20] <XXCoder1> tiny but works
[10:56:46] <XXCoder1> it was ugly hack to get my ancient captioning machine to work with it
[10:57:00] <JT-Shop> nice
[10:57:12] <XXCoder1> I use dvd machine - > vcr -> caption -> vcr -> eyeclops
[10:57:21] <XXCoder1> yes thats two vcr machines
[10:57:42] <XXCoder1> im using em as cheapass conversion of format (rca to coaxial then back(
[11:01:27] <CaptHindsight> cooling a 20W+ led is challenging for many
[11:01:56] <XXCoder1> bigass copper heatsink with stirling fan on it
[11:02:03] <CaptHindsight> many CPU heatsink and fans are good enough for 100W leds
[11:02:31] <CaptHindsight> just hard to find the space inside a projector for them
[11:02:42] <XXCoder1> http://media.treehugger.com/assets/images/2011/10/stirling.jpg
[11:02:48] <XXCoder1> too bad its just concept
[11:03:05] <XXCoder1> one awesome thing is that it means led wont die in sudden blackout
[11:03:10] <CaptHindsight> that would be ok for 10W or so
[11:06:08] <_methods> peltier coolers won't work?
[11:07:06] <CaptHindsight> peltier (like a heatsink or heatpipe) just move heat from one place to another
[11:07:44] <CaptHindsight> you could use a peltier to move the heat from the back of the LED to a heat spreader and then off into the ambient air
[11:08:26] <_methods> i have no idea i just thought maybe for space constraint situation maybe a peltier
[11:09:00] <CaptHindsight> or a water cooling system to move the heat outside the projector
[11:09:39] <CaptHindsight> http://www.legitreviews.com/images/reviews/1784/intel_rts2011lc_035.jpg
[11:10:00] <XXCoder1> bah just get bigger stirling cooler lol
[11:10:11] <CaptHindsight> http://www.ledwv.com/uv/uv-led-405nm-100w-p-738.html
[11:10:43] <XXCoder1> 100w
[11:10:53] <XXCoder1> challenging to keep cool I gess
[11:12:33] <CaptHindsight> http://ledsmater.en.alibaba.com/product/386149801-210832012/120W_UV_LED_area_light_source_curing_system.html
[11:12:56] <CaptHindsight> just like a cpu heatsink+fan combo
[11:13:41] <XXCoder1> dang
[11:13:50] <XXCoder1> how many lumens would that be
[11:14:20] <CaptHindsight> it's in a very narrow band
[11:14:37] <CaptHindsight> so you don't use lumens like you might for white light
[11:15:15] <XXCoder1> but how bright would end result be?
[11:15:22] <CaptHindsight> 4000mW/cm2 (385-400nm)
[11:15:41] <CaptHindsight> 4 watts /cm^2
[11:16:12] <XXCoder1> I guess thats like using 4w light a cm away
[11:16:20] <XXCoder1> hitting 1cmx1cm area
[11:16:34] <CaptHindsight> if the 4w lamp was 100% efficient
[11:16:47] <XXCoder1> yeah I used that assumation too
[11:20:31] <CaptHindsight> if you use 1 lumen/cm2 = 1.464129 mW/cm2 then 2700 lumen/cm2
[11:21:01] <XXCoder1> jeez thats powerful
[11:21:37] <CaptHindsight> yes a 10W 405 or 450nm led will leave you seeing spots for quite some time at 3ft
[11:21:45] <XXCoder1> im sure projector would cause some losses, it projects rgb after all
[11:22:11] <CaptHindsight> depends on the projector and optics
[11:22:25] <XXCoder1> CaptHindsight: guess what lumens eyeclops project lol
[11:22:48] <CaptHindsight> but a 2w led at 405nm can get you 1 sec cure times at 100um layers
[11:24:17] <XXCoder1> cool heh
[11:24:42] <XXCoder1> hm so you use projector to make circuit or what
[11:24:49] <XXCoder1> using uv to cure
[11:25:15] <CaptHindsight> http://education.mrsec.wisc.edu/309.htm
[11:25:29] <XXCoder1> oh yeah
[11:26:14] <XXCoder1> you make and sell projectors for that eh
[11:27:09] <CaptHindsight> photopolymers, components and systems
[11:27:33] <CaptHindsight> it's just another tool
[11:27:51] <CaptHindsight> you really need hybrids for most things
[11:28:20] <XXCoder1> I was thinking that it would somehow convert light to be useable as rgb projector lol
[11:28:20] <CaptHindsight> just like a toolkit vs a set of screw drivers
[11:28:28] <XXCoder1> bit misunderstanding on my part
[11:28:46] <CaptHindsight> you came in late
[11:29:14] <XXCoder1> lol yeah
[11:31:31] <XXCoder1> lol http://i.crackedcdn.com/phpimages/photoshop/5/3/8/371538_v1.jpg

[12:40:20] <jack16> can anyone recommend good Chinese carbide endmill (preferably on aliexpress)?
[12:40:46] <jdh> no such thing afaik
[12:42:06] <SpeedEvil> The sad thing is there almost certainly is
[12:42:10] <SpeedEvil> you just can't find it
[12:42:48] <SpeedEvil> http://www.alibaba.com/product-detail/Borosilicate-glass-beads-for-sandblasting_1801140597.html
[12:42:52] <SpeedEvil> amused me recently
[12:42:59] <SpeedEvil> Borosilicate, with no boron
[12:45:35] <jack16> Actually, this makes sense. There is no chlorine in table salt (NaCl)
[12:46:22] <SpeedEvil> Err - no.
[12:46:35] <SpeedEvil> There is no boron in the mixture at all - even chemically combined
[12:47:15] <jack16> never mind, did not see context
[13:10:34] <_methods> who was talkin about adventure time?
[13:11:09] <_methods> http://www.solestruck.com/search/Dr.%20Martens%20X%20Adventure%20Time
[13:11:17] <_methods> was that pete
[13:17:26] <CaptHindsight> part of that problem is the loss in translation from Chinese to English
[13:18:26] <CaptHindsight> i was wondering some of my partners there would use very odd phrases in English
[13:19:17] <Tom_itx> speak of the devil
[13:20:00] <CaptHindsight> when I asked I discovered that their English instructors and the textbooks were completely free native English speakers and writers/editors
[13:21:31] <CaptHindsight> what I see it lots of copying of English test from one ad to another without any edits or in their minds the description they use is what they believe to be accurate
[13:21:54] <CaptHindsight> sorry my spelling here went to hell
[13:22:12] <CaptHindsight> it/is test/text
[13:22:28] <Tom_itx> it's 'irc' speak
[13:22:57] <Tom_itx> if you read it quick enough your mind sees it correctly
[13:23:45] <CaptHindsight> my favorite was fuselage for body (non-aircraft) and "in my mind" vs "I think" or "In my opinion"
[13:28:13] <_methods> PetefromTn_: found you some boots lol
[13:28:23] <_methods> http://www.solestruck.com/search/Dr.%20Martens%20X%20Adventure%20Time
[13:31:01] <CaptHindsight> _methods: I wish I had saved your link to that 3d printable cosplay outfit
[13:31:30] <CaptHindsight> with raygun, helmet etc
[13:32:25] <Tom_itx> hah
[13:32:43] <_methods> jsjsj
[13:32:45] <_methods> oops
[13:32:50] <_methods> hahah hold on
[13:33:15] <_methods> http://www.thingiverse.com/thing:199786
[13:33:30] <_methods> my favorite use for 3d printing
[13:33:40] <CaptHindsight> yeah, thats the one
[13:33:59] <_methods> pretty much sums up #reprap
[13:34:11] <CaptHindsight> working on an article and I want to include that as an example
[13:34:16] <_methods> hahahah
[13:34:36] <_methods> the embodiment of the 3d printing world
[13:41:12] <_methods> this one is pretty lol
[13:41:15] <_methods> http://www.thingiverse.com/thing:684631
[13:41:28] <_methods> need a tap and die.....just 3d print one
[13:43:02] <zeeshan> lol wtf
[13:43:22] <_methods> don't think about it too much......your brain might implode
[13:43:30] <_methods> it just is
[13:43:53] <_methods> thingiverse is a source of much amusement for me
[13:44:02] <_methods> probably sorta like working at the patent office
[13:44:06] <Jymmm> ...and disgust for me.
[13:44:34] <CaptHindsight> how else to you cut threads for your cheese parts?
[13:44:43] <_methods> or tap your candle collection
[13:44:57] <zeeshan> i wonder if i bought a 3d printer
[13:45:07] <zeeshan> if ill turn into a tard
[13:45:18] <_methods> yes
[13:45:24] <zeeshan> =[
[13:45:34] <zeeshan> to me 3d printer is useful for printing covers
[13:45:43] <jdh> 'turn into'
[13:45:49] <_methods> great for quick enclosures and stuff
[13:45:50] <zeeshan> jdh: hush
[13:45:56] <_methods> prototyping for rough fit
[13:46:10] <_methods> super hero costumes
[13:46:12] <jdh> isnt JT making one?
[13:46:22] <_methods> he said buy one
[13:46:25] <_methods> making one is diff
[13:46:27] <JT-Shop> he's trying to
[13:47:09] <_methods> custom monopoly board pieces
[13:49:48] <JT-Shop> http://3dtopo.com/lostPLA/
[13:50:20] <_methods> why didn't he print the sprues too?
[13:50:42] <FinboySlick> Haha, just saw the Cyclops one... That poor guy needs to scale the straps down or bulk up.
[13:54:09] <JT-Shop> he probably didn't want to wait that long for the sprue and vent to print
[13:54:17] <_methods> ahh true
[13:54:17] <CaptHindsight> http://www.develop3d.com/blog/2014/09/making-stuff-lost-wax-casting-3d-printing-cnc-milling-solidscape-roland
[13:54:52] <FinboySlick> That lostpla thing didn't work so bad.
[13:54:56] <_methods> i would think he would get a better sprue pathway with them being connected together fully in print
[13:55:14] <_methods> looks like he lost one corner of that bracket
[13:55:16] <CaptHindsight> http://www.inside3dp.com/sla-oldest-method-3d-printing-still-best/
[13:57:11] <JT-Shop> crap it's snowing again and they are huge flakes
[13:57:58] * Tom_itx just thinks JT-Shop likes to play with fire and gunpowder
[13:58:06] <CaptHindsight> JT-Shop: PLA with glue gun is for low res and not in a hurry, SLA is for higher res and print rates
[13:58:25] <Tom_itx> sun is out and snow is going away
[13:59:39] * JT-Shop is all for fast and good and cheap
[13:59:57] <Tom_itx> pick 2
[14:00:17] <_methods> hehe
[14:00:21] * furrywolf wants all three!
[14:00:46] <CaptHindsight> Z-axis vs 3 axis
[14:01:00] <CaptHindsight> used projector vs extruder
[14:01:13] <CaptHindsight> materials are about the same price
[14:02:27] <tjtr33> any thoughts on sla for lost-'wax'? (mold cores) any preferable material?
[14:02:36] <CaptHindsight> like everything diy cnc, it all depends on your scrounging skills
[14:02:44] <JT-Shop> I'd have to find a projector...
[14:03:37] <furrywolf> wow, I just measured 229A into my inverter. that be a new record.
[14:03:43] <CaptHindsight> tjtr33: you use resins with very low to no inorganic materials so no to low ash when burned out
[14:04:37] <tjtr33> JT-Shop, https://stlouis.craigslist.org/search/sss?sort=rel&query=video+projector
[14:04:57] <tjtr33> thx CaptHindsight
[14:07:17] <zeeshan> anyone know how to place a stock 45 degree
[14:07:22] <zeeshan> from the x axis
[14:07:24] <zeeshan> in mastercam
[14:07:50] <JT-Shop> tjtr33, which one would be good for SLA?
[14:08:11] <Tom_itx> zeeshan what about smartcam? group all, then 2d rotate
[14:08:18] <zeeshan> no smart cam
[14:08:31] <Tom_itx> i'm sure it's similar
[14:08:36] <CaptHindsight> you just want to avoid any DLP projector with the "white dots" problem
[14:08:54] <CaptHindsight> the white dots are stuck micro-mirrors
[14:09:09] <_methods> why would you place teh stock 45?
[14:09:21] <Tom_itx> _methods so it will fit on his mill :)
[14:09:28] <_methods> if you need to do something funky with the stock make an stl
[14:09:29] <CaptHindsight> they will place unwanted spots/lines into your prints
[14:09:41] <_methods> of your custom stock and its orientation
[14:10:13] <_methods> then import the stl into your stock from file
[14:10:17] <tjtr33> about white dots http://www.fixyourdlp.com/2012/04/24/the-affordable-solution-to-white-dot-syndrome-on-your-dlp-tv/
[14:10:51] <_methods> if you're just trying to orient the part that is another story
[14:11:18] <tjtr33> JT-Shop, I'd say any of those epsons, but asking which one is like asking 'which mobo is good for linuxcnc' :)
[14:11:36] <tjtr33> really really moot
[14:11:51] <CaptHindsight> Epsons are all LCD so the only supplier for resin is me
[14:12:21] <tjtr33> oh! lucky im close, but whats the alternative?
[14:13:40] <furrywolf> why is resin so annoyingly expensive?
[14:13:43] <CaptHindsight> LCD's use color filters on the LCD's, Blue is at 450-460nm, and the other resins drop off >420nm
[14:13:52] <zeeshan> methods
[14:13:53] <zeeshan> you were right
[14:13:54] <zeeshan> that worked
[14:13:59] <CaptHindsight> furrywolf: it's the same or lower than PLA
[14:14:19] <JT-Shop> yea, my luck not having a PHD in SLA I'd get the wrong thing and just be tossing money in the fire
[14:14:25] <furrywolf> I mean compared to buying products made of plastic. the resin costs many times more than what a commercial finished product would cost.
[14:15:07] <witnit_> what resin are you all talking about?
[14:15:12] <furrywolf> any. :)
[14:15:20] <furrywolf> for anything.
[14:15:40] <jdh> where does the lost pla go?
[14:16:04] <jdh> isnt that a lot of volume to melt and displace?
[14:16:05] <CaptHindsight> up until now it's been the SLA printer makers charging $200+/kg
[14:16:15] <JT-Shop> jdh, you burn it out
[14:16:22] <CaptHindsight> the PLA or resin burns out
[14:16:33] <CaptHindsight> as gas
[14:17:05] <witnit_> so resin = treesap? haha
[14:17:14] <_methods> zeeshan: what worked lol
[14:17:25] <zeeshan> stl
[14:17:27] <CaptHindsight> some are made from plants
[14:17:28] <_methods> ah yeah
[14:17:30] <furrywolf> it's not just cnc stuff... even plain 2-part fiberglass resins are $100/gal...
[14:17:35] <witnit_> im not educated in such things
[14:17:37] <_methods> you can save your stl's from ops also
[14:17:40] <_methods> to use in other ops
[14:17:52] <_methods> like say you need to do work on lathe after mill
[14:18:01] <_methods> you can save your mill stl from ops on mill
[14:18:06] <_methods> then use that for your stock on lathe
[14:18:18] <_methods> when you run simulator
[14:18:25] <_methods> there is an option to save the stl
[14:18:38] <zeeshan> its still not fully working right
[14:18:44] <_methods> yeah it has issues
[14:18:52] <_methods> hard to align correctly sometimes
[14:18:57] <zeeshan> yes
[14:18:59] <zeeshan> its 45 degree
[14:19:05] <zeeshan> but its not aligned at the starting point of the stock
[14:19:09] <_methods> yeah
[14:19:31] <_methods> what version are you using
[14:19:44] <zeeshan> mastercam for sw
[14:19:51] <zeeshan> x7
[14:19:52] <_methods> hmm
[14:19:55] <_methods> i'm on x4
[14:20:14] <zeeshan> i have the origin defined in both my part
[14:20:20] <zeeshan> and stl raw stock
[14:20:21] <zeeshan> as the same
[14:20:23] <zeeshan> yet it doesnt align lol
[14:20:25] <CaptHindsight> furrywolf: photopolymers are ~$30/Kg and up in low volumes
[14:20:31] <_methods> i've had issues liek that before
[14:21:07] <_methods> i always have to mess around to get it lined up right
[14:21:18] <_methods> i usually just deal with the normal stock
[14:21:35] <CaptHindsight> thermoplastic pellets are $1-2/Kg since they are sold in such high volumes
[14:21:44] <_methods> not usually worth the grief of trying to bring in stl stock
[14:21:49] <zeeshan> hehe
[14:22:19] <_methods> i bring all my stuff in from solidworks with a "stock" block around my part
[14:22:57] <_methods> if i'm worried about fixtures and stuff or dealing with restricted travel situations
[14:23:26] <zeeshan> http://i.imgur.com/OA4XsTI.png
[14:23:30] <zeeshan> see the prob? :)
[14:23:33] <furrywolf> so I need to build a machine that takes pellets as feedstock, then? :)
[14:23:34] <_methods> i always model up my shops machines with a work envelope block on the table also
[14:23:35] <zeeshan> my x and y travel are correct to the machine
[14:23:39] <zeeshan> but the stock is retarded :P
[14:23:50] <CaptHindsight> furrywolf: for FDM yeah
[14:23:51] <zeeshan> with stl i can orient it right
[14:23:53] <zeeshan> but still doesnt line up
[14:24:03] <jdh> we dont say retarded anymore
[14:24:24] <_methods> yeah
[14:24:43] <tjtr33> CaptHindsight, would you recommend single chip DLP units for beginners? ( vs the LCD )
[14:24:58] <_methods> i'd bring the part in oriented normally
[14:25:04] <_methods> then do the stock
[14:25:10] <furrywolf> the epoxy resin I got at a yard sale sat has the original price labels on it... $35/qt for the resin and $11 for the little can of hardener... I really can't believe the materials cost that much more than generic plastic.
[14:25:20] <_methods> then make a angled work offset/plane
[14:25:25] <CaptHindsight> the LCD's don't die and leave spots
[14:25:33] <JT-Shop> http://www.buildyourownsla.com/forum/index.php?sid=4e145d571849a16f146fedb292e708e6
[14:25:45] <DaViruz> what is "generic plastic"?
[14:25:49] <JT-Shop> not a lot of traffic
[14:26:11] * JT-Shop goes to see if the Ferguson will start and try to drag some snow off the driveway
[14:26:20] <CaptHindsight> furrywolf: it depends on the components but the raw materials do start at ~$1/lb
[14:26:34] <furrywolf> snow?! we have the opposite here... it's so bloody hot I turned the a/c on in my van.
[14:27:01] <zeeshan> ah i see methods
[14:27:01] <furrywolf> Temperature: 63.1 F !!
[14:27:03] <zeeshan> lemmne try that :P
[14:27:08] <tjtr33> JT-Shop, good resource thx
[14:27:11] <CaptHindsight> furrywolf: and others are $20/lb
[14:27:17] <PetefromTn_> zeeshan you can just do Xform and then rotate no?
[14:27:31] <_methods> there's no need to really
[14:27:33] <PetefromTn_> _methods No thanks on the boots man...
[14:27:40] <_methods> hahah
[14:27:46] * furrywolf thinks it's more "we're selling to a specialty market so we can jack the price up as much as we want".
[14:27:46] <CaptHindsight> scorching 16F right now
[14:27:48] <_methods> he can just make a plane on that angle
[14:27:58] <_methods> a work coordinate system
[14:28:06] <PetefromTn_> I am not exactly sure what he is trying to do..
[14:28:20] <_methods> he wants the stock to work so he can see a correct simulation
[14:28:29] <_methods> and the work is on an angle across his table
[14:28:36] <_methods> but he's bringing the model in already angled
[14:28:45] <_methods> so mastercam is making a giant sq around it for stock
[14:29:00] <PetefromTn_> if the model is already angled why does he need to rotate anything?
[14:29:18] <_methods> he has it angled the way he wants but the stock feature is making a giant stock around it
[14:29:33] <_methods> his only other option for stock is to import a stock stl
[14:29:41] <_methods> but it's a pain in the ass to align
[14:29:45] <CaptHindsight> it's making a square around the outside of his part
[14:29:50] <_methods> yes
[14:29:56] <_methods> to the extents of the part
[14:29:59] <_methods> on a 45
[14:30:04] <_methods> or whatever angle that is
[14:30:12] <PetefromTn_> in the define stock tab you mean?
[14:30:16] <_methods> yeah
[14:30:21] <CaptHindsight> guessing 43.56 deg
[14:30:25] <_methods> hahah
[14:30:28] <_methods> calibrated eyes
[14:31:23] <CaptHindsight> zeeshan: what angle did you rotate it to, or did you create it ~45?
[14:31:54] <PetefromTn_> https://www.youtube.com/watch?v=y0NuzjlaWHk
[14:31:55] <zeeshan> 45
[14:31:58] <zeeshan> methods you were right again
[14:32:03] <zeeshan> all i needed to do was bring in ym part normally
[14:32:11] <zeeshan> set bounding box
[14:32:15] <zeeshan> rotate origin.
[14:32:27] <_methods> yea
[14:32:41] <CaptHindsight> thats why they pay him the big bucks
[14:32:44] <_methods> hahah
[14:32:47] <zeeshan> hehe
[14:32:57] <_methods> i rarely even rotate the origin though
[14:33:04] <_methods> i just make a work coordinate
[14:33:09] <_methods> and use geometry to define it
[14:33:11] <furrywolf> I want big bucks. :(
[14:33:33] <CaptHindsight> furrywolf: move, you should be able to find lots of work
[14:33:57] <PetefromTn_> I usually just rotate my part to wherever I need it. THe Xform options are amazing.
[14:34:11] <witnit_> I bought (3) 542-312 mitutoyo linear gages for my grinding room, whats a good homebrew sheath to protect the probes?
[14:34:38] <witnit_> also, is it safe to use magnetic bases for these?
[14:36:22] <_methods> i have never used those before sorry
[14:36:35] <witnit_> if they are wonderful and great i will let you know
[14:36:50] <_methods> um those specs are so far beyond anything i'm doing lol
[14:36:58] <_methods> how much were those things
[14:37:03] <witnit_> ebay
[14:37:09] <_methods> wow score
[14:37:11] <witnit_> 120 for all 3
[14:37:14] <_methods> jeebus
[14:37:17] <_methods> nice score
[14:37:28] <_methods> .0000005/in
[14:37:30] <_methods> wtf
[14:37:37] <witnit_> grinding room tho
[14:38:02] <witnit_> so anything that happens to the tool happens to millions of parts :P
[14:38:09] <_methods> well congrats i can only imagine what they go for new
[14:38:20] <witnit_> i dont want to think such things
[14:38:40] <CaptHindsight> $WOW
[14:38:40] <witnit_> probably like 4 each
[14:38:57] <witnit_> or double that i dont know
[14:39:07] <_methods> they use them for profilometers?
[14:40:07] <_methods> i guess using it for a height gauge is a bad idea lol
[14:43:22] <PetefromTn_> neato
[14:44:43] <witnit_> I thought about putting them in an enclosure and having a second probe which would be exposed
[14:44:51] <witnit_> but then, they are big
[14:46:09] <furrywolf> meh. I'm feeling tired and unmotivated today.
[14:46:30] <furrywolf> I'm tempted to go find an excuse to stretch out in the sun instead of doing anything useful.
[14:46:39] <CaptHindsight> inside diameter measuring laser micrometer
[14:48:18] <furrywolf> I might head to HF and pick up their $9 digital thickness gauge... I suspect my mitu is never coming back.
[14:49:43] <jdh> sun?
[14:49:45] <furrywolf> never, ever lend nice tools to people.
[14:49:59] <furrywolf> sun. you know, the big round yellow ball in the sky?
[14:50:35] <furrywolf> bah, the HF one is only .004"? my mitu was .000something...
[14:51:49] <DaViruz> i once lent my µm mitutoyo dial indicator to someone. i got it back with the plunger stuck solid in the innermost position
[14:51:50] <CaptHindsight> http://motherboard.vice.com/read/telescopic-contact-lenses-are-here-commence-newspapering-your-windows
[14:52:03] <DaViruz> i didn't think it possible before that
[14:52:11] <CaptHindsight> welded into place?
[14:52:33] <DaViruz> probably not, that would require some degree of competence
[14:52:54] <furrywolf> probably crashed the machine into it or something
[14:53:21] <DaViruz> i need to take it apart some day and figure out what happened
[14:53:24] <CaptHindsight> I just turned the thumbscrew until it stopped then I used a pipe wrench
[14:53:50] <furrywolf> I bought a snap-on 3/8" drive torque wrench where the drive was bent 45 degrees.
[14:54:01] <CaptHindsight> I don't even lend out hammers anymore
[14:54:19] <furrywolf> overloaded it so much it bent the internal torsion bar and ran the rack clean off the gear it meshed with...
[14:55:07] <CaptHindsight> sk tools
[14:55:29] <CaptHindsight> did that with a 1/2 drive
[14:56:09] <furrywolf> I put socket on a bolt in my bench vise and big-piped it back to center.
[14:56:27] <furrywolf> works great, but of course the calibration is highly suspect.
[15:00:31] <jack16> Is there open-source tools that can generate gcode for something like this from 2d design? http://www.talkshopbot.com/forum/attachment.php?attachmentid=8114&d=1153234175
[15:01:11] <_methods> gcodetools maybe
[15:01:15] <_methods> and inkscape
[15:01:35] <_methods> seems to be oriented to the art side
[15:03:21] <furrywolf> I keep seeing reasons to use inkscape, but never have. one of these days I'll want to actually use my vinyl cutter instead of looking at it, and I'll need to install inkscape...
[15:03:44] <_methods> yeah i use inkscape for mine with inkcut i think
[15:04:51] <skunkworks> image-to-gcode?
[15:05:14] <Rab> I think trying to map those types of 3D contours in Inkscape in a way comprehensible to gcodetools would be nightmarish...seems like LinuxCNC's depth map functionality might be better suited? http://www.linuxcnc.org/docs/2.4/html/gui_image-to-gcode.html
[15:05:15] <_methods> i've never tried image to gcode but that may work also
[15:05:53] <furrywolf> I used an image-to-gcode tool on windows a number of years ago... it's just a simple scanning algorithm.
[15:06:09] <skunkworks> http://www.linuxcnc.org/docs/2.6/html/gui/image-to-gcode.html
[15:06:22] <furrywolf> at least the one I used made no attempt to follow contours or otherwise do anything other than scan a raster pattern.
[15:07:30] <furrywolf> yeah, about like that. lol
[15:08:32] <JT-Shop> well the box blade sucks... gotta swap it for the grader blade
[15:17:11] <furrywolf> why is there such a large jump in generator prices around 5kw? you can pick up a 4kw generator for $50 on craigslist, but a 10kw starts at $2000...
[15:19:06] <furrywolf> if I want to run this planer, I'm going to need a pretty hefty 240v output...
[15:19:17] <furrywolf> same for the plasma cutter
[15:23:13] <jack16> Raster way is not very appealing. I'd prefer pure vector way.
[15:24:06] <jack16> I used inkscape and gcode tools, but never tried "engrave" option.
[15:24:29] <jack16> It seems docs are lacking about this subject.
[15:25:27] <XXCoder1> yeah it gets annoying when internet dont know about something
[15:25:36] <XXCoder1> it took me LONG time to find this video https://www.youtube.com/watch?v=DRvLMVWwILM
[15:25:42] <XXCoder1> so I can finally check car pcv
[15:25:49] <XXCoder1> my car is damn rare
[15:26:55] <furrywolf> ... I've never seen a pcv valve that took a video to change.
[15:28:20] <furrywolf> look it up in your service manual. no video needed.
[15:29:13] <furrywolf> what makes you think yours is bad?
[15:30:12] <XXCoder1> egr errors
[15:30:19] <XXCoder1> many stuff is cleaned or replaced
[15:30:35] <furrywolf> egr is not realted to pcv
[15:30:40] <furrywolf> related
[15:30:50] <XXCoder1> and well like I said my car is rare, very hard to find info. my car bible dont really list how and where
[15:31:03] <furrywolf> do you have a service manual for your car?
[15:31:10] <XXCoder1> http://www.obd-codes.com/p0401
[15:31:12] <XXCoder1> it is
[15:31:34] <jack16> It's actually math problem, finding "straight skeleton".
[15:31:54] <XXCoder1> furrywolf: I has chilton book
[15:32:08] <XXCoder1> but no stright from company service book. service books is all 2.0l
[15:32:52] <furrywolf> what motor do you have?
[15:33:01] <XXCoder1> v6 3.5l
[15:33:05] <XXCoder1> 2.5l
[15:34:51] <furrywolf> dohc?
[15:35:01] <XXCoder1> dohc>
[15:35:03] <XXCoder1> ?
[15:35:09] <furrywolf> 24 valve?
[15:35:15] <furrywolf> there's apparantly a few different 2.5l engines
[15:35:23] <XXCoder1> ohh hmm not sure
[15:35:35] <XXCoder1> mine has round air filter I thought that was custom but..
[15:35:45] <witnit> Monarch lathe - $700 I got so excited when i saw the craigslist ad
[15:35:50] <witnit> not the model I want tho :)
[15:35:54] <XXCoder1> the cut cone anyway
[15:36:12] <XXCoder1> oh yeah
[15:36:15] <XXCoder1> years 1998
[15:36:37] <XXCoder1> mines auto (thats what makes it extra rare)
[15:37:54] <furrywolf> so you have ap0401, insufficient egr flow?
[15:37:59] <zeeshan> witnit
[15:38:00] <zeeshan> which model?
[15:38:01] <zeeshan> http://i.imgur.com/bciApEy.png
[15:38:02] <XXCoder1> p0401
[15:38:05] <zeeshan> yea baby!
[15:38:31] <furrywolf> a p... typo. lol
[15:39:49] <XXCoder1> yra
[15:39:51] <XXCoder1> yea
[15:40:27] <furrywolf> mine says fault in egr vacuum system, egr valve stuck, egr valve diaphragm bad, egr line plugged, bad solenoid, bad wiring, bad pressure sensor, bad pressure sensor hoses, mis-connected pressure sensor hoses, bad sensor wiring, bad "orifice tube". as expected, nothing about pcv.
[15:41:30] <furrywolf> my first test, when presented with that problem, would be to apply vacuum directly to the egr valve and see if the engine stalls.
[15:41:41] <XXCoder1> new egr
[15:41:53] <furrywolf> ok, so it's not the valve. hopefully. :P
[15:42:05] <XXCoder1> dont have anything that can do vacuum unfortunately
[15:42:15] <XXCoder1> trottle is cleaned too
[15:42:16] <furrywolf> any manifold vac line off the engine. :)
[15:42:32] <XXCoder1> I tested umm whats that thing for power and vacuum, its fine
[15:42:59] <witnit> zeeshan, http://fortwayne.craigslist.org/tls/4894057246.html
[15:43:04] <furrywolf> my personal experience is 90% of egr problems are clogged lines.
[15:43:13] <XXCoder1> I did find bit loose connector (in video you can see topmost connector)
[15:43:16] <furrywolf> and remaining 10% being actual failures.
[15:43:27] <XXCoder1> how do I test clogged lines?
[15:43:41] <XXCoder1> most of thin vacuum lines is new
[15:43:45] <furrywolf> first, you apply vacuum to the valve at idle and see if the engine stalls. :)
[15:43:53] <XXCoder1> (old ones literally shattered, took me while)
[15:44:41] <XXCoder1> I guess need clean hose so I can just suck it
[15:44:57] <XXCoder1> blowjob to be sure :P Im experenced with it I guess, what woith nes and all LOL
[15:45:12] <furrywolf> there's a tube that runs from the egr valve down to the exhaust. it's usually what clogs. yours apparantly has additional complication of an orifice tube that creates a restriction that creates a pressure differential that is measured to determine flow.
[15:45:24] <furrywolf> you can't provide enough vacuum by mouth.
[15:45:35] <zeeshan> ah cool
[15:45:55] <XXCoder1> which tube clogs, the thick one bottom or vaccuum on top?
[15:46:15] <witnit> zeeshan, http://s65.photobucket.com/user/macona/media/DSC03137.jpg.html
[15:46:40] <furrywolf> either use a handheld vacuum pump, or run a line from a manifold vac source straight to the valve. disconnect the valve, have a long line with enough room to move around. plug with something, start engine. remove plug, stick finger over end of tube. then stick tube on valve. the engine should stall or substantially bog down.
[15:47:01] <furrywolf> handheld vacuum pump is more precise and doesn't involve disconnecting unrelated vacuum lines for a vacuum source.
[15:47:07] <DaViruz> you can usually generate a pretty decent vacuum by mouth
[15:50:21] <witnit> I bet you could suck a golfball through a garden hose
[15:51:19] <furrywolf> XXCoder1: the one that has exhaust flowing through it and depositing carbon and crap on the walls. :)
[15:51:33] <XXCoder1> the thicker one then lol
[15:51:43] <XXCoder1> would trottle cleaner work?
[15:51:53] <XXCoder1> im not sure where to find other end
[15:51:55] <furrywolf> the vacuum test is a quick way to determine if the problem is actually related to exhaust flow, or is a problem with the control system or sensors.
[15:52:10] <XXCoder1> oxy sensor?
[15:52:11] <FinboySlick> witnit: Holy crap, what a beauty!
[15:52:20] <furrywolf> one end is the egr valve, the other end is your exhaust pipes.
[15:52:22] <witnit> yeaaaaahhh budday
[15:52:38] <XXCoder1> fun. thanks
[15:52:40] <XXCoder1> looking
[15:53:04] <furrywolf> if flow is good, opening the valve full open (by applying unregulated vacuum to it) at idle will usually instantly kill the engine, as exhaust doesn't burn.
[15:53:19] <furrywolf> if the engine dies, you probably have ok flow. if the engine keeps on running, your lines are clogged.
[15:54:01] <furrywolf> if the line is clogged, the usual fix is to run a coathanger down it. but, yours has an orifice tube, which is a complication.
[15:55:23] <furrywolf> unfortunately, my non-factory manual gives very few details.
[15:56:19] <furrywolf> ah, found more details... for some reason a basic system diagram was hidden under pinpoint tests. :P
[15:57:12] <witnit> does anyone know whats going on here? http://www.gadgetbuilder.com/Thomas2.jpg
[15:58:21] <furrywolf> I'll try getting a pdf of it for you
[15:58:33] <FinboySlick> witnit: Threading or an easily repeatable groove depth?
[15:59:45] <witnit> thats what i was thinking, like, easy pullout for locking down the traverse
[15:59:57] <witnit> so you can undercut
[16:00:03] <XXCoder1> thanks
[16:00:13] <XXCoder1> its too hard to apply enough vacuum lol
[16:00:55] <XXCoder1> do other hose to that part constantly supply vaccum? if so I can use it
[16:01:03] <witnit> isnt there a way to create vacume with an air compressor :)
[16:01:10] <XXCoder1> dont own any
[16:01:13] <andypugh> witnit: It’s for threading without disconnecting the nut
[16:01:16] <XXCoder1> brb
[16:01:33] <witnit> andypugh, got ya
[16:02:19] <andypugh> witnit: If you are threading on a metric lathe in imperial or vice-versa then you can’t use the thread counter, so you need to reverse the spindle to return for a second cut. But then you can’t work to a shoulder.
[16:05:16] <andypugh> XXCoder1: I guess you are talking about an EGR valve?
[16:05:27] <witnit> clever
[16:05:28] <andypugh> What sort of engine? Do you have an EVRV?
[16:06:07] <furrywolf> pdf is 1.2MB... got 300K uploaded so far... will be a while.
[16:07:45] <furrywolf> XXCoder1: http://fw.bushytails.net/1998%20Ford%20Contour%202.5l%20EGR%201.pdf yes, the colors are fucked up. alldata can't print properly, ever.
[16:08:10] <furrywolf> if the only code you have is p0401, start at test HE70, if you want to follow their flowchart.
[16:08:24] <witnit> I have an idea for dovetail toolpost, it works great, i been using it for years, but i think it would be easy to profit on if i had a way to harden the metal, anyone will cnc mill and kiln?
[16:08:36] <witnit> with*
[16:09:49] <andypugh> Looks like an EGR with no position loop. I gues it runs closed-loop on MAF alone.
[16:10:31] <furrywolf> andypugh: it uses an orifice tube and measures the pressure drop across it with a differential pressure transducer to determine actual egr flow, rather than caring about the valve position
[16:11:01] <furrywolf> or, as I see it, "more, smaller bits to get coked up"
[16:11:18] <XXCoder1> furrywolf: ok a ? first
[16:11:29] <XXCoder1> is manfold top vacuum source strong enough?
[16:11:35] <furrywolf> yes
[16:11:35] <XXCoder1> if so, it failed test
[16:11:53] <XXCoder1> I replaced one of hoses with egr hose
[16:11:53] <furrywolf> you connected manifold vacuum straight to the vacuum port on the back of the egr valve, and the engine kept running just fine?
[16:12:01] <XXCoder1> then another one to be sure
[16:12:09] <XXCoder1> yeah no change whatsever
[16:12:35] <furrywolf> stick your finger to the end of the vacuum line you used and make sure it has a good vacuum. (engine idling)
[16:12:48] <XXCoder1> it could hold on to my finger a little
[16:13:38] <witnit> get the wifes vacuum and just size your way down to something to work with if you need to keep testing
[16:13:41] <witnit> just an idea :P
[16:13:44] <furrywolf> ok, so either your egr valve is bad, or the line from the valve down to the exhaust is plugged. on your valve, can you visibly see the valve shaft, or feel the diaphragm? (some valves you can, some are enclosed)
[16:14:03] <XXCoder1> witnit: sure so first step is to be married?
[16:14:25] <witnit> it doesnt have to be your wifes vacuum
[16:14:29] <XXCoder1> lol
[16:14:51] <XXCoder1> I dont want to disconnect and buy yet another gasket
[16:15:01] <XXCoder1> I just gonna figure how to find other end
[16:15:10] <furrywolf> picture I found of what should be yours shows it's enclosed
[16:15:23] <furrywolf> disconnect the egr tube from the valve, leaving the valve on the intake.
[16:15:39] <XXCoder1> yeah
[16:15:52] <furrywolf> http://fw.bushytails.net/1998%20Ford%20Contour%202.5l%20EGR%202.pdf is the slightly-helpful section on the egr tube
[16:16:02] <andypugh> Have you sucked on the tube? You can at least feel a leaky diphragm that way,
[16:16:15] <XXCoder1> andypugh: it seals very well
[16:17:02] <furrywolf> andypugh: I'm disinclined to think it's the valve, as he tried the "replace parts and see if it helps" approach and it didn't. :)
[16:17:17] <witnit> if we all were in the same town, we could start a do all machine shop out of a scrapyard and turn profit all day
[16:17:39] <witnit> so many people knowing so much of each field of the industry
[16:17:43] <XXCoder1> I bought egr, then forgot about it as car couldnt run (many water stuff broken)
[16:17:44] <furrywolf> since you had the valve off recently, the tube is probably not TOO badly rusted in place. it might still be tough. do NOT round it. if you can't get it out, get a proper line wrench.
[16:17:53] <XXCoder1> then I used van for a while, fixing part a time
[16:17:58] <XXCoder1> by then return had expired
[16:18:25] <XXCoder1> yeah I made sure to spray wd40 so top part in least should be easoer
[16:18:27] <furrywolf> egr tubes without fail rust in place
[16:18:52] <XXCoder1> and yeah it was tough first time lol I soaked in wd40 few times and waited in order to slowly loosen
[16:19:33] <XXCoder1> picture on other end isnt too clear
[16:19:36] <furrywolf> next step is to remove tube from valve. leave other end attached, just pull tube enough out of the valve that you can rest it on the side of the valve instead of in the port. unplug the vacuum hose to the valve. start the car. does exhaust come out of the tube?
[16:19:37] <XXCoder1> need bit more context
[16:19:45] <furrywolf> it's the top of your catalytic converter
[16:19:58] <XXCoder1> ok be back
[16:20:00] <furrywolf> or manifold
[16:20:04] <furrywolf> might just be manifold. :P
[16:20:20] <furrywolf> whether or not exhaust comes out of the tube, repeat the vacuum-straight-to-valve test.
[16:20:31] <andypugh> Most folk are happy when their EGR valve stops working. Fuel economy tends to improve, though you won’t pass an emissions test
[16:21:23] <furrywolf> with the tube disconnected, if it still doesn't stall when vacuum is applied, the problem is the valve or the intake, or your vacuum source isn't. if it does stall with the tube removed, and there's no exhaust coming out of the tube, you've pretty definitively identified a clogged tube.
[16:21:58] <witnit> "pretty definitively"
[16:22:02] <witnit> hehe
[16:22:31] <witnit> thats the same as being 99 point 9 sure
[16:26:26] <Deejay> gn8
[17:02:24] <XXCoder1> furrywolf: back
[17:02:45] <XXCoder1> hose dont spray any air
[17:03:01] <XXCoder1> however its still pretty in egr
[17:03:26] <XXCoder1> just removed the "nut" and loosen hose but not out since impossible with egr still in
[17:05:18] <furrywolf> you might have to get to the other end, then. normally they can be bent a fair bit without damage, but I've never worked on that car...
[17:05:37] <XXCoder1> its solid metal hose
[17:05:41] <furrywolf> yes
[17:05:55] <furrywolf> I'd hope so, since it has hot exhaust flowing through it. :P
[17:05:57] <XXCoder1> I guess I gonna find other end then
[17:06:01] <XXCoder1> lol ok
[17:06:09] <Nick001-shop> <pcw_home> you around?
[17:06:18] <furrywolf> looks like either your manifold, cat, or cat/manifold combo...
[17:06:25] <XXCoder1> its really really nasty to remove hose from egr
[17:06:35] <pcw_home> Yeah for a bit
[17:06:38] <XXCoder1> good thing I got this special short tool from dad or grandfather
[17:06:43] <XXCoder1> it looks likw 80 years old
[17:06:50] <XXCoder1> looks like jaws but sideways
[17:07:10] <XXCoder1> dunno what its called but its wrench where you can adjust size
[17:07:33] <Nick001-shop> is there a manual for the 7i76? The site has it for an ethernet card.
[17:07:50] <XXCoder1> well out for now, working on car
[17:09:45] <pcw_home> The store might be wrong, the website is correct
[17:10:01] <pcw_home> or google 7i76man
[17:12:27] <Nick001-shop> OK - found it. Is there a 7i24 yet? Want to get that next Hardinge converted.
[17:21:35] <XXCoder1> furrywolf: back
[17:21:51] <XXCoder1> no way for me to access cyclyst convertor area
[17:21:57] <XXCoder1> no proper jack or anything
[17:22:07] <XXCoder1> wonder how much shop would charge to just clean hose
[17:27:27] <pcw_home> 7I24?
[17:28:17] <furrywolf> a lot. and you're not even sure that's what's wrong. :P
[17:28:49] <XXCoder2> yah
[17:28:56] <pcw_home> bbl
[17:29:19] <XXCoder2> woot finally made my vp work again
[17:29:26] <XXCoder2> half broken hardware
[17:30:01] <furrywolf> the manual does say you have to jack and support the car...
[17:36:49] <XXCoder2> > $150
[17:36:51] <XXCoder2> not surpised
[17:38:22] <zeeshan|2> why is the maximum number of entries in the tool table limited to 56?
[17:46:58] <jack16> Does artcam output gcode that linuxcnc can use?
[17:50:48] <Tom_itx> zeeshan|2 because 57 was taken
[17:50:56] <zeeshan|2> ?
[17:51:21] <Tom_itx> that's been discussed before
[17:51:32] <zeeshan|2> where
[17:51:33] <JT-Shop> it
[17:51:45] <JT-Shop> 's a limitation of something I forget
[17:55:52] <witnit_> anyone every dropped the spindle pulley from a hardinge dv-59?
[17:55:58] <witnit_> every*
[17:56:00] <witnit_> dang
[17:56:02] <witnit_> ever*
[17:57:04] <witnit_> I got the spindle but something is holding the pulley suspended still and im not sure how it comes apart
[17:58:01] <andypugh> Very high qulaity lathes have a separate set of bearings just for the pulley so that belt noise doesn’t affect the finish.
[17:59:40] <andypugh> There is a picture of such an arrangement on the Crowell lathe here: http://www.lathes.co.uk/cromwell/index.html
[17:59:43] <Crom_> Wow my phone has been running askchat since saturday
[17:59:59] <andypugh> (See the sectional drawing)
[18:02:21] <Crom_> Time to try making the flexable boning clamp press pieces out of 1/2 aluminum
[18:02:47] <XXCoder1> furrywolf: im kinda stick
[18:02:49] <XXCoder1> stuck
[18:03:08] <XXCoder1> cant access the other end without anything to lift car
[18:03:59] <Crom_> Xxcoder bigger hammer always works for me
[18:04:20] <witnit_> andypugh, Very similar design, see pulley in center is captured by flange on each side
[18:04:23] <witnit_> http://www.lathes.co.uk/cataract/img6.gif
[18:04:29] <Crom_> Cant block the jack up end on cribbibg?
[18:04:45] <witnit_> spindle slides into this pulley/sleeve
[18:05:34] <witnit_> once the spindle is out, the sleeve/pulley drops 1/8th inch and is still captured
[18:05:58] <XXCoder1> Crom_: lift car with hammer? lol
[18:07:00] <Crom_> It can be done using wedges
[18:07:56] <XXCoder1> think can use brick (large ones)
[18:08:02] <XXCoder1> but not sure if 3 inches is enough
[18:10:13] <Crom_> Dont use cinder blocks on thier sides and put a board underneath and a couple on top
[18:12:49] <andypugh> You probably need to extract the bearings too.
[18:15:54] <zeeshan|2> la la la
[18:15:58] <zeeshan|2> fu mastercam post processor
[18:16:07] <zeeshan|2> gimme g33.1!
[18:24:10] <furrywolf> XXCoder1: how do you not have a jack? do you just hope you never get a flat tire?
[18:47:58] <witnit_> andypugh, I got it, I was afraid to use the BFH on it but, it was just surface rust on the outer spindle(pulley vibration damper) and it had it froze tight, I put an aluminum hub over it smacked it rather hard and the whole thing dropped though the front
[18:48:13] <witnit_> through*
[18:49:30] <witnit_> I try to use BFH as last resort, luckily it will go back together nicely when i clean all this rust.
[18:50:20] <witnit_> my intentions are to remove the vbelt pully and add a toothed belt system and servo, any suggestions while i have this apart?
[18:51:18] <andypugh> TBH id you can mount an encoder on the spindle then a V-belt will be just as effective as a toothed belt with whatever motor you choose.
[18:52:16] <MacGalempsy> evening all
[18:52:25] <witnit_> I thought of this, but it seems attaching encoder will be hard as well, I want to do have a high accuracy on it, but not high cost
[18:54:37] <witnit_> I dont know how to translate the spindle revolutions into an encoder unless I add tooth pulley to it somehow, or a large bore rotary.
[18:56:01] <MacGalempsy> question, I see on the newest version of linux cnc, there is a selection for dual mesa 7i77. what would I need to do to the HAL file to make it a 7i77 and 7i84?
[19:13:05] <furrywolf> witnit: I'm planning on a large encoder disc, like http://members.shaw.ca/SWSTUFF/spindle-encoder.html
[19:13:22] <witnit_> tyty
[19:14:57] <furrywolf> the g-code file from that site is quite nice, and will generate discs of any size
[19:15:05] <XXCoder1> furrywolf: thankfully found onme
[19:15:20] <XXCoder1> looked all over the damn bottom. didnt find it
[19:16:06] <furrywolf> http://members.shaw.ca/SWSTUFF/spindle-encoder.ngc edit variables for any size disc with any number of slots
[19:16:29] <XXCoder1> one inch, billion slots
[19:16:44] <furrywolf> sure, as long as you have a small enough endmill. :P
[19:16:57] <witnit_> MacGalempsy, http://translate.google.com/translate?hl=en&sl=ru&u=http://www.cnc-club.ru/forum/viewtopic.php%3Ff%3D41%26t%3D2881&prev=search
[19:17:03] <witnit_> maybe that will help
[19:17:08] <XXCoder1> nah its finer than size of atoms lol
[19:17:13] <XXCoder1> impossible
[19:17:45] <XXCoder1> your pdf download is amazing but need context unfortnately
[19:17:54] <XXCoder1> I do suspect its closer than I thought though
[19:18:13] <furrywolf> actually, no, the g-code is smarter than you.
[19:18:13] <furrywolf> (DEBUG, Unable to cut encoder because #<_endmill_dia> cutter is too large for a #<_encoder_cycles> cycle #<_main_track_dia> dia disk)
[19:18:13] <furrywolf> m2
[19:18:23] <XXCoder1> nice
[19:18:44] <XXCoder1> try ricious size like .0001 mm
[19:18:48] <XXCoder1> em
[19:19:00] <furrywolf> also, if you think there's fewer than a billion atoms in an inch, you failed physics and chemistry. :)
[19:19:14] <XXCoder1> actually youre right lol
[19:19:28] <XXCoder1> theres very large number of atoms across thickness of paper
[19:19:35] <XXCoder1> let alone inch
[19:20:11] <furrywolf> as I said, it's a rather nice file.
[19:20:39] <furrywolf> nothing in it is incredibly complicated, it's just complete and easy to use.
[19:20:51] <XXCoder1> apparently (cant trust yahoo answers) paper thickness has 1 million atoms
[19:21:10] <XXCoder1> yeah best programs or scripts or whatever is simple to use, complex result
[19:21:19] <XXCoder1> bad programs has complex process to make something simple]
[19:22:31] <XXCoder1> http://www.physlink.com/Education/AskExperts/ae49.cfm
[19:22:38] <XXCoder1> probably more crediable answer
[19:23:03] <andypugh> 25nm for an atom? Sounds big.
[19:23:09] <witnit_> buffing compound is doing wonders to this spindle, this stuff must be 35 years old ahhahaah
[19:23:11] <XXCoder1> nm is tiny
[19:23:12] <witnit_> smells terrible
[19:23:41] <XXCoder1> unless maybe they really meant um
[19:23:58] <andypugh> Also foil is thinner than paper
[19:24:02] <XXCoder1> it is
[19:24:32] <andypugh> Foil is 40um and paper is 4 thou :-)
[19:24:34] <XXCoder1> paper thickness alum would be bit stiff, probably enough to make it hard to use
[19:25:06] <XXCoder1> heh I could imange some teenager anwering "umm um"
[19:25:10] <furrywolf> hydrogen is 53pm according to whatever source google uses for its factoid blurbs.
[19:25:16] <andypugh> http://www.periodictable.com/Properties/A/AtomicRadius.v.wt.html
[19:25:27] <andypugh> 1 pm = 1e-12 m
[19:26:02] <andypugh> So, the milllion-atoms-to-a-sheet of paper is out by a factor ofd 1000
[19:26:04] <furrywolf> according to wikipedia, "Consequently, the smallest atom is helium with a radius of 32 pm, while one of the largest is caesium at 225 pm."
[19:26:20] <andypugh> Sorry, I missed one out.
[19:26:24] <XXCoder1> interesting that hyrogen is bigger
[19:26:28] <XXCoder1> atoms is weird
[19:26:38] <andypugh> The factor is 1,000,000
[19:26:39] <MacGalempsy> witnit_: thanks, I will give it a look
[19:26:54] <XXCoder1> andy thanks
[19:27:18] <furrywolf> bbl, need to empty out the back of my car and head to work.
[19:27:54] <andypugh> 1 millionth of a sheet of paper is 23nm. And I want to change my mind again because i remembered my previous figure as being in um and it wasn’t :-). Back to the factor 1000.
[19:28:19] <andypugh> A sheet of paper is 1 billion atoms thick.
[19:28:23] <XXCoder1> lol yeah sometimes its hard to keep track
[19:28:30] <andypugh> I used to have to know this stuff.
[19:28:40] <XXCoder1> yeah? what job?
[19:29:00] * furrywolf guesses the job was "finishing school"
[19:29:05] <furrywolf> bbl
[19:29:10] <XXCoder1> suppose paper was made from Cesium
[19:29:17] <XXCoder1> how many atoms would it be? lol
[19:29:20] <andypugh> http://link.springer.com/article/10.1007/BF00275452
[19:29:47] <XXCoder1> scientist
[19:29:54] <furrywolf> cesium foil is very much like paper, and easy to get... :P
[19:30:36] <XXCoder1> I do want the first/second most dense material in form of half inch dia tube, inch long
[19:30:45] <XXCoder1> I have samples of few elements in that form
[19:30:47] <andypugh> Osmium
[19:31:10] <XXCoder1> bet it would cost more than gold
[19:31:25] <andypugh> A pint of mercury is astonishingly heavy, and osmium is much heavier.
[19:31:47] <XXCoder1> andypugh: other thing I always wanted was tungsein "gold" bar
[19:31:53] <XXCoder1> like one they always show in tv
[19:32:06] <XXCoder1> I want one close to gold density to show how tv stuff is impossible
[19:32:14] <XXCoder1> like stuffing 10 gold bars lol
[19:32:19] <andypugh> http://www.ebay.com/itm/Osmium-metal-solid-1g-pellet-/391039127294
[19:32:45] <XXCoder1> unfortunately not in shape I want
[19:33:18] <andypugh> I have found myself wondering what “they” could do if you left a shipping contianer full of solid osmium somewhere inconvenient.
[19:33:41] <XXCoder1> lol it would crush shipping cargo bottom probably
[19:34:19] <XXCoder1> and if in pebbles, bust out and spill
[19:34:25] <XXCoder1> killing people if they was close lol
[19:35:59] <XXCoder1> http://www.periodictable.com/Properties/A/AtomicRadius.sp.wt.html
[19:36:05] <andypugh> A 40’ container is 67m3 (I checked Wikipedia). I am going to assume that Osmium is 28 tons per cubic meter. So thats close to 2000 tons in a single brick. I don’t think that there are many 2000 ton cranes. And osmium has a high melting point, is very hard, and so would be very hard to chop up. :-)
[19:36:08] <XXCoder1> interesting pattern
[19:36:43] <XXCoder1> wtf with that dip
[19:36:57] <XXCoder1> around element 60
[19:37:11] <andypugh> <chagrin> 22.6 kg.m3, I misremembered
[19:37:34] <roycroft> that sounds like an excuse for some good explsives, andypugh
[19:38:45] <andypugh> A 1500 ton brick of something that melts at 3000C would laugh at anything short of a nuke.
[19:39:16] <XXCoder1> tungsein is fun one. it would freeze in lava
[19:39:32] <XXCoder1> because lava is so damn cold compared to molen tungsein
[19:40:27] <XXCoder1> if we ever find way to "freeze" peices of space we could finally contain melted tungsein and test its properies
[19:40:31] <andypugh> Osmium is not far behind.
[19:41:05] <andypugh> 3695 for Wg, 3306 for Os
[19:41:24] <andypugh> W, I mean. Wg is something else
[19:41:49] <andypugh> (Though I know not what)
[19:42:01] <XXCoder1> I remember usa (or russia or both?) used nukes to weld 3 feet thick metal
[19:42:05] <XXCoder1> only way to do that
[19:42:12] <witnit_> this hardinge lathe i got was a military owned lathe, it appears they actually put new bearings in it instead of just buying a whole new lathe
[19:42:15] <andypugh> (I cheated on the melting points, I used Wikipedia)
[19:42:15] <witnit_> strange
[19:42:16] <witnit_> hahaha
[19:42:27] <XXCoder1> damn
[19:42:30] <XXCoder1> thats nice
[19:42:44] <andypugh> XXCoder1: not so. You can weld 3’ metals with electron beams.
[19:42:55] <XXCoder1> didnt think they had it then
[19:43:05] <XXCoder1> cold war early era
[19:43:32] <witnit_> somebody definately took it apart before, improperly it seems according to how deep these marks are from hammering on a bar, but these bearings couldnt be tighter
[19:44:01] <andypugh> witnit_: Sounds good.
[19:45:39] <andypugh> I did an electron-beam welding project once. My sample was 100mm thick slabs of stainless and carbon steel welded edge to edge with no weld-prep. But the machine used can do 1m (again, with no weld prep)
[19:46:34] <XXCoder1> thick.
[19:48:44] <andypugh> Don’t ask how I got there but: http://en.wikipedia.org/wiki/Thallium#Toxicity
[19:49:27] <andypugh> So, if you are poisoned by Thallium they feed you micrometer blue and it comes out the other end. That must be a sight to behold.
[19:50:38] <XXCoder1> ouch
[19:54:26] <andypugh> “Just eat this iron cyanide sir, it will make you feel better”
[19:54:35] <XXCoder1> lol
[19:54:48] <XXCoder1> well salt is made from 2 seriously toxic elements
[19:55:34] <andypugh> I don’t think sodoum is at all toxic. Though it would be hard to eat without injury :-)
[19:56:19] <XXCoder1> sodium true not toxic but not fun stuff either
[19:58:12] <LeelooMinai> It's highly reactive - sometimes causing explosions:)
[19:58:25] <witnit_> there are three kinds of people out there, ones who use phillips screws on machinery, ones who dont, and people who paint over phillips screws
[19:58:29] <witnit_> pricks
[19:58:34] <XXCoder1> lol
[19:59:03] <XXCoder1> there is 10 kinds of people, those who know binary and others
[19:59:50] <XXCoder1> there is 2 kinds of people, those who can figure from incomplete data.
[20:00:11] <witnit_> :)
[20:00:14] <witnit_> i like that 1
[20:01:40] <roycroft> i generally replace phillips head screws on machinery with button head screws or socket head cap screws
[20:01:47] <witnit_> SAMES
[20:02:45] * jdh takes another look at Z's encoder sensor bolts
[20:02:51] <roycroft> on some machinery, namely some of the chinese stuff that comes with pot metal screws, i replace them all as soon as i get the machine
[20:03:18] <roycroft> on machines that have decent screws in the first place i usually swap them as i have cause to remove them
[20:03:19] <jdh> slippery slope
[20:03:43] <roycroft> you have to think of the chinese machines as kits
[20:03:51] <roycroft> and the parts are held together for shipping with pot metal fasteners
[20:04:47] <andypugh> There is nothing inherently wrong with the Phillips head
[20:04:54] <roycroft> no, there is not
[20:05:29] <XXCoder1> andypugh: in least its not standard
[20:05:48] <XXCoder1> I can't adjust my van tps because of its damn standard screws
[20:05:52] <roycroft> which is why i don't swap them out immediately when they're well-constructed phillips head screws
[20:05:57] <XXCoder1> would love it was it was bolts
[20:06:17] <zeeshan|2> fak
[20:06:21] <zeeshan|2> i think my Y servo has a bad bearing
[20:06:30] <zeeshan|2> rattling :p
[20:06:31] <andypugh> I think the problems people have are due to the smaller sizes almost working, and that Pozi drivers almost work too.
[20:07:04] <witnit_> andypugh, except improper fit between driver and head resulting in extra rear pressure to keep the taper point from acting as a wedge and forcing the screw driver out of the hole
[20:07:10] <witnit_> no there isnt
[20:07:46] <witnit_> the problem with phillips is the angles of the head and seat, nothing else
[20:08:15] <XXCoder1> witnit_: if I recall theres 2 variants of philips? and chinese ones is halfway in between so it fits nothing perfectly
[20:08:16] <roycroft> use a properly-constructed screw and a quality, correctly-sized screwdriver and you're fine
[20:08:22] <andypugh> Pozi is more parallel, but even with the Phillips the angles are small.
[20:08:27] <zeeshan|2> robertson ftw
[20:08:44] <XXCoder1> do you guys mill philips screwdrivers? lol
[20:08:59] <roycroft> one of the biggest "problems" with phillips screws is that the average homeowner not only has just a #2 phillips screwdriver, but is also not aware that there is more than one size
[20:09:04] <andypugh> I think part of the problem is that Phillips is intended as a means to drive relatively low-tensile fasteners.
[20:09:30] <tjtr33> i thought Prinz bits were same angles as Phillips but came to complete point
[20:09:37] <andypugh> Yes
[20:09:46] <witnit_> agreed, but i dont think they should ever be used on machinery
[20:10:01] <witnit_> cap screw or flat head
[20:10:29] <roycroft> i prefer hex socket screws when i'll be removing and reinstalling repeatedly
[20:10:32] <andypugh> (well, Frearson / Reed / Prince ) http://en.wikipedia.org/wiki/List_of_screw_drives#Frearson
[20:10:33] <renesis> stainless button head cap screws ftmfw
[20:10:36] <renesis> big ones
[20:11:12] <roycroft> that said, socket head screws are significantly more expensive than similar size phillips head screws
[20:11:22] <andypugh> Actually, for button heads I might prefer a slot to the hex that fits
[20:12:05] <roycroft> for permanant installation i usually use phillips head
[20:12:18] <renesis> no way man hex socket buttons are hot sex!
[20:12:18] <andypugh> (Interesting page, I have not knowingly seen a “Mortorq”
[20:12:36] <malcom2073> phillips: For spinning off and making impossible to reuse the screw once it's tight :P
[20:12:52] <renesis> ya srs
[20:12:57] <witnit_> my only real complaint is having to apply backpressure to the driver 9 times out of 10 with phillips style
[20:13:25] <andypugh> Hex buttons (and hex countersunk) actually have rather a small drive radius for the diameter. I would bet on Phillips against Hex for the same screw material.
[20:14:12] <andypugh> But you don’t generally see them in the same material.
[20:14:22] <witnit_> nothing too high tech here, we can all talk about screws hahaha
[20:15:07] <witnit_> sometimes i see people in here chatting and am just so completely lost
[20:24:06] <_methods> screw that
[20:26:13] <XXCoder1> Jymmm: they did it. Only 71 hours left, they did 30 achievements. someone at college posted pic of 100 people with cat ears
[20:29:21] <andypugh> I do hoe that they were not real cats ears?
[20:30:17] <XXCoder1> lol
[20:30:24] <XXCoder1> nah but man that was hard one
[20:30:38] <XXCoder1> yet easiest one to complete to cover 30th and final one
[20:31:47] <XXCoder1> andypugh: https://www.kickstarter.com/projects/elanlee/exploding-kittens/posts/1137509
[20:33:13] <XXCoder1> they went far past 100 person requirement really
[20:33:23] <XXCoder1> if there was 250 one they probably reachjed it too lol
[20:35:16] <witnit_> im playing the "color the shaft with a sharpie, slide it in the sleeve and see where the rub marks are" game.
[20:35:54] <witnit_> every friggin place the last guy smacked the spindle edge with a punch it appears :/
[20:36:22] <andypugh> You need some Prussian Blue
[20:36:25] <witnit_> yep
[20:36:42] <witnit_> havent used the stuff since i was in highschool shop class
[20:37:26] <XXCoder1> got it cheap?
[20:37:41] <witnit_> the lathe?
[20:37:47] <XXCoder1> yea
[20:37:51] <witnit_> 250
[20:37:57] <XXCoder1> 250k?
[20:38:12] <witnit_> 250.00
[20:38:20] <XXCoder1> dang
[20:38:24] <XXCoder1> and new bearing?
[20:38:34] <witnit_> seems that way
[20:38:56] <witnit_> no tailstop,turret, crosslide, or collet closer
[20:39:02] <witnit_> stock*
[20:39:16] <witnit_> just the lathe and about 6 layers of paint
[20:39:42] <XXCoder1> selectly remove paint for cool finish
[20:39:54] <XXCoder1> assuming different colors
[20:40:04] <witnit_> well my options are, brown, orange and machine grey
[20:40:12] <witnit_> and rust
[20:40:17] <witnit_> lots of that color
[20:40:17] <XXCoder1> and bare
[20:40:30] <witnit_> oh yes but currently bare and rust are one in the same
[20:40:37] <XXCoder1> lol ok
[20:41:06] <witnit_> im pretty sure they stored it under a waterfall
[20:41:21] <XXCoder1> machine one with nature
[20:44:28] <andypugh> Does anyone know lots about beziers and splines?
[20:44:56] <XXCoder1> ask 2005 me
[20:45:00] <XXCoder1> he should know
[20:46:04] <andypugh> Right, so I should finish off this time machine I have been working on?
[20:46:12] <XXCoder1> why?
[20:46:16] <XXCoder1> just use timeirc client
[20:46:29] <XXCoder1> though I forgot what irc server I used to use then
[20:46:40] <XXCoder1> I wasnt on freenode then
[20:46:46] <andypugh> Does 2015 you know anything?
[20:46:54] <XXCoder1> unfortunately forgot a lot
[20:47:03] <XXCoder1> I do know theres quite a few node types
[20:47:10] <XXCoder1> those control how line bends around
[20:47:11] <andypugh> Like, for example, how Boehm’s algorithm works in practice?
[20:47:21] <XXCoder1> boehm heh forgot that
[20:48:49] <andypugh> I am trying to reprsent a b-spline in SVG, which only does quadratic and cubic beziers, you see.
[20:49:18] <XXCoder1> yeah utterly forgot that lol
[20:49:29] <XXCoder1> I think some of node types do that?
[20:49:44] <XXCoder1> just draw a line and delete all nodes but 3
[20:49:53] <XXCoder1> set middle node to one of those types
[20:50:43] <andypugh> Yes, all very easy to say, but what does that mean?
[20:51:21] <XXCoder1> lemme load inkscape
[20:51:50] <andypugh> Inside the Autodesk API I can split a spline into sub-curves, but they never have fewer than 5 knots, and that can’t be a cubic Bezier, as fas as I can tell
[20:51:57] <XXCoder1> https://www.dashingd3js.com/svg-paths-and-d3js
[20:52:00] <XXCoder1> any help?
[20:52:32] <andypugh> XXCoder1: https://bugs.launchpad.net/inkscape/+bug/1421865
[20:53:09] <andypugh> Err, no, I got that far
[20:53:20] <XXCoder1> yah was pretty sure
[20:55:04] <witnit_> what do you need to know exactly andypugh?
[20:55:58] <XXCoder1> this converts list of points to cubic spline http://www.inkscapeforum.com/viewtopic.php?f=16&t=11671
[20:56:22] <XXCoder1> it has link to pdf about splines and bezier curves
[20:56:28] <XXCoder1> might be useful
[20:59:08] <andypugh> XXCoder1: It’s too late to get too far in to this tonight. But: http://forums.autodesk.com/t5/inventor-customization/inventor-sketchspline-to-svg-bezier/td-p/5499976
[21:00:30] <XXCoder1> good article
[21:00:40] <XXCoder1> nurbs to b-spline seems complex
[21:00:52] <andypugh> XXCoder1: Hmm, that might be the paper I need, I will have a look tomorrow.
[21:01:14] <XXCoder1> hope its usefyl
[21:01:30] <zeeshan|2> f autodesk alias
[21:01:34] <zeeshan|2> abd bsplines !
[21:01:42] <zeeshan|2> it was confusin :P
[21:01:44] <andypugh> I could probably use the Autodesk Inventor “spline to strokes” method to get points and then arc-fit them and that would be fine, but unsatisfying.
[21:02:01] <zeeshan|2> """"
[21:20:01] <witnit_> these hardinge spindles are significantly more robust than i was expecting.
[21:27:53] <XXCoder1> andypugh: I wonder about physics of one thing
[21:28:09] <XXCoder1> can you make some strong metal ballon thin enough to hold vacuum inside
[21:28:12] <XXCoder1> would it float?
[21:28:21] <andypugh> I wonder about the Physics of _everything)
[21:28:40] <andypugh> Yes
[21:28:51] <XXCoder1> why dont anyone ever make one
[21:29:00] <andypugh> Why bother?
[21:29:09] <XXCoder1> it would last forever I would think
[21:29:33] <andypugh> Even quite a thick balloon full of vacuum would float.
[21:29:49] <jdh> you just need a container rigid enough to hold vacuum and be lighter than air.
[21:29:56] <witnit_> metal balloon that would float? you mean a boat?
[21:30:02] <XXCoder1> creative folding would do it I guess
[21:30:04] <witnit_> ahjahjahj
[21:30:24] <XXCoder1> folding to increase strength is quite old
[21:30:31] <XXCoder1> witnit_: I didnt say boat
[21:30:37] <XXCoder1> float in air
[21:30:44] <witnit_> ohhhh
[21:30:46] <XXCoder1> density must be lower than air
[21:30:50] <andypugh> Ah, sorry, witnit asked the right question. What do you want it to float _in_
[21:31:06] <XXCoder1> yeah guess didnt give full details
[21:31:09] <XXCoder1> srry
[21:31:29] <andypugh> Floating in water, no trouble at all.
[21:31:34] <witnit_> maybe if you fill it with a helium
[21:31:38] <andypugh> Floating in air. Harder.
[21:31:43] <XXCoder1> witnit_: helium is easy
[21:31:58] <witnit_> but a vaccuum does not mean lighter by volume does it?
[21:32:00] <XXCoder1> vacuum is harder since it would have to stay full size
[21:32:05] <witnit_> like enough
[21:32:18] <XXCoder1> it is lighter, nothing has zero densiry
[21:32:28] <andypugh> Why not equalise with Helium, which is only a bit more dense than vacuum but can have equal pressure.
[21:32:35] <XXCoder1> pressure is huge though and would crush metal thing down
[21:32:49] <XXCoder1> andypugh: helium that low density
[21:32:58] <XXCoder1> hyrogen is even lower but interesting
[21:32:59] <andypugh> Yeah,
[21:33:19] <andypugh> Actually Hydrogen is not that mucj less dense
[21:33:27] <XXCoder1> wonder if can cheat a little
[21:33:29] <andypugh> H2 v He1
[21:33:35] <XXCoder1> hot helium
[21:33:40] <XXCoder1> enough to hold pressure
[21:33:54] <XXCoder1> till it gets high enough and cool and would be balanced high up
[21:34:02] <XXCoder1> so it will last longer before exploding
[21:34:22] <witnit_> I wonder if it would make an earth shattering kaboom
[21:34:28] <andypugh> That’s an interesting idea. Do the analysis
[21:34:37] <zeeshan> anyone know what kind of oil a cnc machine gear box should take
[21:34:40] <XXCoder1> unfortunately I cant do it lol
[21:34:43] <zeeshan> usually i dumped 75w90
[21:34:47] <zeeshan> in my lathe spindle box
[21:35:40] <andypugh> This is a bit like an argument I had at work. “This is at 99% vacuum, but it would need to be 10x as strong to support 99.9% vacuum….
[21:35:49] <CaptHindsight> http://www.batteryspace.com/lifepo4-26650-rechargeable-cell-3-2v-3300-mah-19-8a-rate-10wh---un38-3-passed-ndgr.aspx anyone have any problems with their Lithium iron phosphate batteries?
[21:38:23] <andypugh> (To be fair, that vacuum discussion was in units that made it less clear what the difference was)
[21:39:40] <andypugh> CaptHindsight: No. But a more relevant battery chemistry discussion for many of us is: http://www.truetex.com/buttons.htm
[21:40:17] <andypugh> The cheap calipers come with LR44 and those are not the same as the SR44.
[21:40:48] <XXCoder1> andypugh: would cheap batteries affect caliper accuracy?
[21:41:33] <andypugh> No, They still work, but have you noticed how they spend about 1 week OK then 9 months flashing for low battery?
[21:41:45] <XXCoder1> mines lasting just fine
[21:41:57] <XXCoder1> $25 calipers lol
[21:42:07] <XXCoder1> accuracy I wouldnt trust it past .01
[21:42:09] <andypugh> I bet you an LR44 that yours has an SR44 in it
[21:43:28] <XXCoder1> dunno maybe lol
[21:43:42] <XXCoder1> furrywolf: hey whats those strip thing that help me connect wires together
[21:44:02] <XXCoder1> one with screws parallel with strips of metal
[21:44:09] <XXCoder1> *called
[21:44:18] <andypugh> Anyway, I should have been asleep hours ago.
[21:45:19] <witnit_> I will need toothed pulley with 3.200in bore
[21:45:21] <witnit_> :/
[21:57:01] <XXCoder1> hope you find it
[22:14:02] <witnit_> okay, who wants to make me timing pulley with 3.2 bore? =D
[22:17:36] <bobo_> zeeshan: Maho for vertical Quill - vertical head drive - horzintal work spindle drive ger - main transmission , uses CL46 lub oil
[22:19:24] <bobo_> CL 46 =Mobile -- DTE mediam =Mobile DTE 25
[22:38:01] <bobo_> zeeshan Shell Tellus oil C46 =Cl46
[22:39:01] <bobo_> Maho slide way oil =CG LP 220
[22:41:49] <bobo_> CG LP 220 ---- Mobile =slideway oil 220 , Shell = Tonna oil TX 220
[22:44:31] <bobo_> I do remember Nick Mueller saying Shell slideway oil reduced stiction
[22:59:35] <zeeshan> im gonna use a bit thicker
[22:59:39] <zeeshan> iso68
[22:59:43] <zeeshan> mobil vactra2
[23:00:17] <zeeshan> witnit: just buy a pulley
[23:00:18] <zeeshan> and rebore it
[23:01:22] <zeeshan> http://princessauto.com/en/detail/tellus-s2v-all-season-68-hydraulic-oil/A-p8337123e
[23:01:50] <witnit_> yeah i can but my lathe is trash and i have not a 4 jaw chuck so i will have to indicate it on my mill and bore it
[23:02:07] <zeeshan> gotta use what you got :P
[23:02:22] <XXCoder1> witnit_: hammer and chasel ;)
[23:02:47] <witnit_> if anyone has an appropriate pulley they dont need and want to bore it and mail it to me I wont complain =D
[23:06:01] <zeeshan> bobo
[23:06:03] <zeeshan> 220 is some heavy oil!
[23:06:18] <zeeshan> its almost like motor oil
[23:12:33] <bobo_> zeeshan CL46 and CG LP 220 are old designations , don't know what they = in present day equiv. big thing is not to desolve seals
[23:17:53] <XXCoder1> wish im electrician

[23:18:00] <XXCoder1> fun with hacking
[23:18:22] <zeeshan> bobo_:
[23:18:26] <zeeshan> 46 is the weight
[23:18:29] <zeeshan> same w/ 220
[23:18:31] <zeeshan> shrug :P
[23:23:31] <bobo_> zeeshan you are correct , but it is also what was added vers what is now added to the oils that can also help or hinder these old machines
[23:23:55] <zeeshan> im gonna grab some of that s2v
[23:23:56] <zeeshan> oil
[23:24:12] <zeeshan> do you know how much quantity it takes?
[23:24:14] <zeeshan> i put a gallon in
[23:24:17] <zeeshan> and its still not full :P
[23:24:28] <zeeshan> i notice there are 2 inspection glasses
[23:24:38] <zeeshan> one near the input pulley from the electric motor
[23:24:44] <zeeshan> and one near the Y glass scale
[23:27:11] <bobo_> I don't know . guess half way on both sight glasses. front glass may be horz spindle ?
[23:27:30] <zeeshan> i dont see a seperate fill hole fo rit
[23:27:32] <zeeshan> ill keep adding oil
[23:27:35] <zeeshan> till i see em change :P
[23:29:39] <bobo_> glug-glug-glug ,,,,,, why is the floor slippery?
[23:30:23] <zeeshan> lol
[23:30:26] <zeeshan> no leaks :P
[23:30:38] <bobo_> good
[23:30:44] <zeeshan> im a bit annoyed though
[23:30:47] <zeeshan> i think my y axis servo
[23:30:50] <zeeshan> has a bearing motor bearing
[23:30:53] <zeeshan> its gotten louder
[23:31:06] <zeeshan> ill need to take it off
[23:31:08] <zeeshan> and try to spin the pulley
[23:31:10] <zeeshan> and see whats up
[23:33:06] <bobo_> motor may be easier than ball screw end bearings/thrust bearings
[23:35:22] <zeeshan> before i take anything apart
[23:35:31] <zeeshan> i wanna try lubricating the entire system :P
[23:35:50] <zeeshan> they charged my credit card
[23:35:55] <zeeshan> so i think fittings are in :)
[23:37:56] <bobo_> lub fittings ----where did you order them from ?
[23:38:44] <zeeshan> https://www.flocomponents.com/
[23:40:52] <bobo_> they are on your side of the border . Great-----less hassel
[23:41:01] <zeeshan> yes
[23:41:06] <zeeshan> and cheap too
[23:41:27] <zeeshan> devco wanted min order of 400
[23:41:27] <zeeshan> lol
[23:41:47] <zeeshan> these guys cost me $60 for 10 fittings of each kind
[23:41:50] <zeeshan> and some hose
[23:43:49] <bobo_> guess who got the sale now and mayby future sales . got to wonder about the Big business thinking
[23:49:59] <bobo_> zeeshan l "T" nuts ---looked as if you were making some . will you be threading them for metric hardeware or inch hardeware ?
[23:50:12] <zeeshan> 3/8" :)
[23:50:50] <bobo_> that is my thought also
[23:51:40] <zeeshan> metric is ok to find
[23:51:45] <zeeshan> inch is easiest
[23:51:52] <zeeshan> every store has it
[23:53:04] <bobo_> metric hold down "kits" are more $
[23:56:38] <witnit_> I think this is great idea and should probably consider it more often myself "<zeeshan> before i take anything apart
[23:56:38] <witnit_> <zeeshan> i wanna try lubricating the entire system :P"
