[00:03:11] <PetefromTn_> Well just got back from shopping for groceries. AMAZES me what a family of four can eat in a week around here.
[00:05:44] <XXCoder> lol
[00:08:10] <andypugh> It amazes me how long a singleton who hates to shop can last on the food in the house. :-) i have managed 3 weeks on a 1 week shop :-)
[00:09:13] <XXCoder> :D
[00:09:23] <XXCoder> you should check out soylent then andy
[00:09:36] <andypugh> I have “reserves” that I don’t want
[00:09:53] <XXCoder> can make homebrew version, buy month worth, cook only when you wanna enjoy food
[00:10:00] <XXCoder> just mix and drink otherwise

[01:02:57] <andypugh> How do you change the DRO format in Axis? I have at least once told someone how to do it (and it is easy) but I am struggling tonight.
[01:03:03] <Connor> neither one will run on my 12.04 LTS says something about libpci3
[01:03:35] <Connor> but, this isn't a linuxcnc install.. and no 5i25 installed.
[01:04:45] <andypugh> I don’t think Mesaflash needs anything except the hardware

[02:21:50] <andypugh> No, but it looks pretty stiff for the size and useful.
[02:22:37] <skunkworks> it is pretty stout - for a short thing...

[03:11:34] <zeeshan|2> iphone sux @ taking pics
[03:11:35] <zeeshan|2> :D
[03:12:59] <XXCoder1> lol
[03:13:10] <XXCoder1> I wonder if theres way to make sphere by 2.5 axis machine
[03:13:24] <zeeshan|2> yea
[03:13:27] <zeeshan|2> its called using a lathe!
[03:13:27] <zeeshan|2> :P
[03:13:28] <XXCoder1> I know half of one can be made but dunno how to secure it when its flipped
[03:13:32] <XXCoder1> lol
[03:13:36] <XXCoder1> true I guess
[03:13:47] <andypugh> Which iPhone? I sold my iPhone 4S to friend and he has largely abandoned his point-and-shoot camera. (and he is a keen photographer, he owns a http://kmp.bdimitrov.de/lenses/primes/extreme-tele/K1000f8.html
[03:13:50] <Tom_itx> epoxy in a fixture
[03:14:08] <zeeshan|2> the way i'd do it is machine a round stock with the imprint of a hemisphere
[03:14:20] <zeeshan|2> then i'd remove it, and put a stock and make a sphere as best as possible wit hthe lathe
[03:14:31] <zeeshan|2> then i'd stick the sphere in the hemisphere
[03:14:38] <zeeshan|2> and machine off the rest
[03:14:42] <XXCoder1> really if has lathe no reason to use 2.5 xis at first place
[03:14:53] <humble_sea_bass> the 4s was the first "ok" camera on an iphone
[03:14:54] <zeeshan|2> andypugh: iphone 4
[03:14:55] <humble_sea_bass> still p bad
[03:15:12] <zeeshan|2> i'm not much into phones
[03:15:27] <zeeshan|2> my phone is mainly for calling , web surfing when im at a shop trying to find a part
[03:15:33] <zeeshan|2> and email ;p
[03:15:42] <zeeshan|2> camera is just an added benefit!
[03:15:52] <humble_sea_bass> i use a crap ass galaxy nexus whuich i love love love
[03:16:03] <humble_sea_bass> but the camera is hot garbage
[03:16:06] <XXCoder1> I use touchpad modified to have cm11
[03:16:15] <XXCoder1> camera almost couldnt be shitter
[03:16:22] <zeeshan|2> haha
[03:16:43] <XXCoder1> weird thing is that it takes better pics than orginial webos.
[03:16:58] <andypugh> I actually use my iPhone more than my “real” camera because it is a shorter lens, and the image really is pretty good
[03:17:08] <humble_sea_bass> XX do you use a choclear
[03:17:23] <XXCoder1> what for? its been 38 years, lil late lol
[03:17:33] <XXCoder1> I literally dont have brain parts for hearing now
[03:18:10] <XXCoder1> well I still have some but you know what happens to body parts that dont get used.
[03:18:36] <humble_sea_bass> meh, you'd be surprised. my friend got the most amazing unit though with bluetooth, so her iphone beams everthing into her skull which is pretty rad
[03:18:50] <humble_sea_bass> like a fancy induction loop
[03:18:52] <XXCoder1> lol guess so, but was your friend late deafened?
[03:19:14] <XXCoder1> or had it since before 13 yr old?
[03:19:24] <andypugh> I have read that by the age of 4 japanese kids can no longer learn to tell “L” from “R”
[03:19:55] <humble_sea_bass> she always had hearing issues, but then got hit by a truck and lost sight as well, so technology and the choclear are supper important
[03:20:15] <humble_sea_bass> andypugh: stop that
[03:20:15] <XXCoder1> yeah even partial hearing allows brain to develop hearing centers normally
[03:20:40] <XXCoder1> I'm one of fairly rare 100% deaf. most deaf has slight trace of hearing. so they can hear boomboxes
[03:20:43] <XXCoder1> I cant lol
[03:20:59] <XXCoder1> I literally read book right in front of one boombox, it was great massage
[03:21:04] <humble_sea_bass> I understand the issue with pathways etc,
[03:21:20] -!- pcw_home has quit [Remote host closed the connection]
[03:21:58] <andypugh> humble_sea_bass: Stop what?
[03:22:17] <humble_sea_bass> spreading false fact about the letter R and L
[03:22:33] <humble_sea_bass> they are not equivalent
[03:23:15] KreAture is now known as KreAture_Zzz
[03:23:25] <XXCoder1> anyway I see no reason whatever to turn from deaf into crappy hearing person
[03:23:38] <XXCoder1> I got great deaf family, I work at deaf company, so on
[03:24:23] <humble_sea_bass> I also undestand deaf culture and how it is pretty tight

[03:27:17] <XXCoder1> its oretty cool I guess. its bit hard to think of external view of culture LOL
[03:27:26] <andypugh> Photos: https://plus.google.com/photos/108164504656404380542/albums/5747722155741347649 has a mix of “real camera” and “iphone” pics (and you can read which in the right-hand pane, I think) Hard to see any systematic difference.
[03:28:25] <humble_sea_bass> i know ppl that live on different parts of the hard of hearing /deaf spectrum and the changes they've observed socially etc
[03:29:04] <andypugh> And the iPhone 5 camera is better again. it seems to break all the rules I learned in Optics at college.
[03:29:56] <XXCoder1> you heard of "ILY" handsign? lately I keep hearing that deaf stole it from hearing culture
[03:30:08] <XXCoder1> ugg yeah right. I have been using it since late 70s
[03:30:18] <XXCoder1> when I'm 4 or so
[03:30:34] <andypugh> (perhaps not, a very sensitive pinhole camera is almost ideal, so a tiny lens and a very good sensor might be great)
[03:31:10] <XXCoder1> I heard its sensor size that matters more, but then I'm no photography exper
[03:32:29] <andypugh> humble_sea_bass: Are you sure that the L/R thing is a false fact?
[03:33:40] <humble_sea_bass> it wouldn't be fair if it was true

[03:34:29] <zeeshan|2> dun dun dun
[03:34:33] <zeeshan|2> we see a selfie for andypugh
[03:34:36] <zeeshan|2> in the reflection
[03:34:45] <andypugh> zeeshan|2: A bar of white metal for re-surfacing engine bearings
[03:34:54] <zeeshan|2> ah

[03:34:57] <zeeshan|2> i know what this is!
[03:35:11] <zeeshan|2> a planer
[03:35:30] <zeeshan|2> i really don't see what it's application are
[03:35:35] <andypugh> actually, a shaper.
[03:35:42] <XXCoder1> in least its not acciental nude selfie :P
[03:35:43] <zeeshan|2> i call it a planer! ;p
[03:35:56] <zeeshan|2> like its basically a lathe
[03:36:00] <zeeshan|2> but moving in a straight line
[03:36:35] <andypugh> Planers and shapers are similar, but in a shaper the tool moves, and in a planer the work moves

[03:36:48] <zeeshan|2> !!!!!
[03:37:00] <zeeshan|2> andypugh: ah
[03:37:08] <zeeshan|2> i was thinking of a shaper
[03:37:16] <zeeshan|2> cause i noticed the ways on the head
[03:37:35] <andypugh> And I am not a great welder. So what?
[03:37:42] <zeeshan|2> im a master aluminum welder
[03:37:43] <zeeshan|2> !
[03:37:58] <zeeshan|2> i know the problem right away
[03:38:10] <zeeshan|2> its not you
[03:38:13] <zeeshan|2> its the metal you're welding
[03:38:22] <andypugh> I am keen to learn
[03:38:30] <zeeshan|2> the bottom plate looks like shitty 1000 series anodized stuff
[03:38:33] <zeeshan|2> which doesn't weld well at all
[03:38:53] <XXCoder1> can anodize part be grinded off?
[03:38:59] <zeeshan|2> yea it can
[03:39:03] <zeeshan|2> but still doesnt change the fact its 1000 series
[03:39:07] <andypugh> It hasn’t broken yet
[03:39:12] <zeeshan|2> it won't break
[03:39:27] <zeeshan|2> it just looks bad and will be 30% of the strength of the base material
[03:39:30] -!- AR_ has quit [Ping timeout: 255 seconds]
[03:39:36] <zeeshan|2> (the 30% is a number out of my butt, but im trying to make a point)
[03:40:08] <zeeshan|2> and if you pressurize the top tube, i guarantee you'll see little air bubbles in a water tank at the black spots
[03:40:08] <XXCoder1> tip for android device noobies - if it adverises wifi as best feature its shitty
[03:40:16] <andypugh> It is the joint between the tube and the console here: https://plus.google.com/photos/108164504656404380542/albums/5747722155741347649/5754374155813339394?pid=5754374155813339394&oid=108164504656404380542
[03:40:18] <XXCoder1> example http://tech.woot.com/?ref=gh_tc_2
[03:40:31] <zeeshan|2> not a big deal then
[03:40:35] <zeeshan|2> doesn't look like its taking much weight
[03:41:03] <zeeshan|2> what kind of welder?
[03:41:06] <zeeshan|2> transformer or inverter
[03:41:36] <andypugh> AC HF inverter, but a cheap one.
[03:41:52] <andypugh> Probably my 3rd alu weld ever.
[03:42:15] <XXCoder1> even though its pretty shitty tablet I'm slightly tempted, it has 1 gb ram and has microhdmi
[03:42:23] <XXCoder1> might be cheapass smart tv lol
[03:44:18] <zeeshan|2> lemme show you some
[03:44:26] <zeeshan|2> portfolio!
[03:44:32] <zeeshan|2> i'm not a pro
[03:44:45] <zeeshan|2> well i do it a lot, but not for a living

[03:47:06] <zeeshan|2> 4th picture
[03:47:11] <zeeshan|2> to the right
[03:47:16] <zeeshan|2> i like that one
[03:47:39] <zeeshan|2> i like the intake manifold ones too
[03:47:49] <zeeshan|2> the tank ones with 3 fittings
[03:47:58] <zeeshan|2> i wanted to make them heavy welds cause that thing holds fuel in it
[03:48:04] <zeeshan|2> and it was going in a guys race car
[03:48:42] <zeeshan|2> theres 1 thing similar with all those pics
[03:49:23] <zeeshan|2> 6xxx or 5xxx series aluminum
[03:49:51] <andypugh> zeeshan|2: I am actually not too sad about _my_ welds, considrering I am absolutel not a welder.
[03:50:04] <zeeshan|2> im not trying to make you sad!
[03:50:15] <zeeshan|2> but i've experimented a lot with it
[03:50:31] <zeeshan|2> so i pass tips when i can :P
[03:50:40] <andypugh> 3rd down looks hard
[03:51:12] <zeeshan|2> you know when people say
[03:51:20] <zeeshan|2> "sand down the area you're welding"
[03:51:32] <zeeshan|2> with aluminum, when you try to do that with a dirty brush or sand paper
[03:51:36] <zeeshan|2> you actually end up making the problem worse
[03:52:00] <zeeshan|2> and since your sand paper usually is made out of aluminum oxide, some of it embeds onto the aluminum
[03:52:03] <zeeshan|2> when you're sanding it
[03:52:14] <zeeshan|2> even after you clean it with acetone and you try to weld it
[03:52:18] <zeeshan|2> you'll see those little 'black' spots
[03:52:20] <zeeshan|2> rise up
[03:52:29] <zeeshan|2> its the silly pieces of aluminum oxide breaking off
[03:52:34] <zeeshan|2> (at least thats my theory on it)
[03:52:51] <zeeshan|2> i just crank up balance to 50/50 (self cleaning 50%, penetration 50%)
[03:53:07] <zeeshan|2> if its fresh metal, i just clean with acetone and weld away
[03:53:39] <zeeshan|2> if its old metal, i heat it up with propane to burn off the oil and impurities on the surface and below the surface (aluminum is pretty porous so it absorbs oil/grease/dirt)
[03:53:48] <zeeshan|2> then acetone and weld
[03:54:08] <zeeshan|2> i've never been able to weld any aluminum that has been anodized
[03:54:14] <zeeshan|2> even after removing the layer of anodizing
[03:54:16] <XXCoder1> cant you use some non-alum stuff like steel mesh
[03:54:21] <zeeshan|2> it just doesnt look pretty
[03:54:29] <zeeshan|2> XXCoder1: again the same problem
[03:54:37] <zeeshan|2> if its steel wool, some of it likes to embedd
[03:54:50] <XXCoder1> HMM use cnc to mill surface? :D
[03:54:51] <andypugh> I tried to make an underfloor heating manifold for my parents. 12” x 1” tube, 12 x 1/4” nipples for the pipes. Stainless Steel. I tried to TIG it, but the nipples were so much littler than the tube that I couldn’t make it work. I ended up using silver solder.
[03:55:00] <zeeshan|2> XXCoder1: that would be the best
[03:55:24] <zeeshan|2> your text came up as a bunch of symbols
[03:55:24] <zeeshan|2> lol
[03:55:38] <zeeshan|2> 12x1 mm tube?
[03:55:39] <XXCoder1> me or andy?
[03:55:41] <zeeshan|2> andypugh:
[03:55:57] <XXCoder1> he used quotes imperial system inches
[03:55:59] <toastyde1th> Single point dimond surface planer! the only way to surface aluminum.
[03:56:47] <andypugh> Yeah, imperial. I am bi-unitular.
[03:57:00] <zeeshan|2> what do i set my language option to
[03:57:06] <andypugh> I measure in metric and guess in Imperial.
[03:57:11] <zeeshan|2> 'default text encoding: use langauge encoding'
[03:57:48] <zeeshan|2> you said
[03:57:54] <zeeshan|2> 12inch by 1" thick tubing right?
[03:58:06] <zeeshan|2> and 12 inch by 1/4 inch thick nipples
[03:58:19] <zeeshan|2> those are some huge pipes
[03:59:02] -!- tjtr33 [tjtr33!~tjtr33@76-216-190-185.lightspeed.cicril.sbcglobal.net] has parted #linuxcnc
[04:00:00] <zeeshan|2> tell meee
[04:01:46] <andypugh> 12” long. 1” diameter, 1/4” wall. then 1 nipple every .92037” which was 1/4” bore and 9mm OD, and machined down from that.
[04:01:55] <zeeshan|2> i cant seer the symbols
[04:02:08] <zeeshan|2> all i see is 12 weird symbol, another weird symbol then long
[04:02:26] <jdh> 12� long
[04:02:29] <zeeshan|2> jdh
[04:02:30] <zeeshan|2> damhn you
[04:02:52] <XXCoder1> ' " ~!@#$%^&*()_+
[04:03:06] <XXCoder1> whats it look like? all just weird symbols?
[04:03:14] <zeeshan|2> i just need to know the thickneess of the nipples
[04:03:18] <XXCoder1> you might just need better font. I use inconsula
[04:03:19] <zeeshan|2> 0.25 wall main pipe
[04:03:32] <andypugh> That’s very strange, all I am using are inch/quote symbos.
[04:03:38] <zeeshan|2> its my kvirc
[04:03:53] <XXCoder1> just assume double quote each time yous ee symbol
[04:04:24] <zeeshan|2> andypugh is killing me with inch dimensions and then a metric dimension
[04:04:24] <zeeshan|2> hehe
[04:04:51] <zeeshan|2> so nipples are .25 bore, .354 od
[04:05:01] <zeeshan|2> 0.052 wall thickness
[04:05:12] <zeeshan|2> do you remember what amps you were welding that at?
[04:05:17] <andypugh> In metric: 32mm OD pipe 6mm wall. 12 x 9mm OD 6mm ID nipples
[04:06:07] <zeeshan|2> you'd want to weld that at 40 amps to 45 amps
[04:06:21] <zeeshan|2> to get a max penetration of 40 to 45 thou
[04:06:24] <zeeshan|2> (inches)
[04:06:48] <zeeshan|2> if you set it to more than 52 amps, you'll blow right through
[04:06:52] <andypugh> I tried 20 / 30 / 40 amps, I couldn’t melt both at the same time.
[04:07:09] <zeeshan|2> and if its exactly at 52 amps, you'll still blow through unless you're superman and can move fast
[04:07:30] <zeeshan|2> you gotta start the puddle first at the thicker material
[04:07:38] <zeeshan|2> as soon as you see the puddle at the thicker material
[04:08:14] <zeeshan|2> at that point you wanna dump in some filler
[04:08:43] <zeeshan|2> and you'll see itll somewhat make a weak joint with the nipple
[04:09:04] <zeeshan|2> once that tack is there, you can go back to your normal 45 degree optimal angle between the two pieces
[04:09:16] <zeeshan|2> and keep filling in
[04:09:20] <andypugh> I kind-of know this stuff. But the puddle wouldn’t bridge and my filler rods have more area then the machined-down nipples
[04:09:21] <zeeshan|2> i dunno if that makes sense
[04:10:09] <zeeshan|2> its hard to explain
[04:10:14] <zeeshan|2> but that first tack is the hardest one
[04:11:01] <zeeshan|2> the scenario you're describing i deal with when im welding 0.0625 inch wall tubing
[04:11:20] <zeeshan|2> and trying to weld a npt fitting to it (which has roughly a wall of 0.25")
[04:11:54] <andypugh> I just decided that 1mm wall thickness small parts to 6mm wall thickness big parts was too hard.
[04:11:54] <XXCoder1> if nothing else, use bondo. ;)
[04:12:02] <XXCoder1> lay em on thick. :P
[04:12:13] <zeeshan|2> its not if you keep the heat at the big part first
[04:12:34] <andypugh> Too hard for _me_
[04:12:40] <zeeshan|2> PRACTICE!
[04:12:41] <zeeshan|2> or i will beat you
[04:12:51] <andypugh> I only had two parts.
[04:13:02] <andypugh> And both needed to work
[04:13:06] <XXCoder1> beating will go on as long as morale is down
[04:13:57] <andypugh> Silver solder was easy, net, and unlikely to leak.
[04:14:44] <zeeshan|2> i need to learn to silver solder
[04:14:47] <zeeshan|2> never done it in my life
[04:16:45] <zeeshan|2> make a video of you welding stainless steel

[04:17:42] <zeeshan|2> see the bunch of couplers?
[04:17:46] <zeeshan|2> (orange black)
[04:18:01] <zeeshan|2> right below it is .25 wall fitting welded to 0.0625 wall tubing
[04:19:39] <zeeshan|2> what you should try to do is take a piece of 1/16 inch stainless sheet metal piece
[04:20:00] <zeeshan|2> and weld it to a thick piece of stainless pipe
[04:20:16] <zeeshan|2> straight fillet weld and see what happens
[04:20:43] <zeeshan|2> once you're done with it, you will have yourself a stainless steel axe
[04:30:08] -!- lyzidiamond has quit [Remote host closed the connection]
[04:42:39] <andypugh> Part of the problem is that I have to accept that I cant see well enough to weld little stuff any more.
[04:44:29] <andypugh> When you can’t focus at less than 24 inches and are peering through a mask, it’s not easy,
[04:45:20] <XXCoder1> I'm starting to wonder why not create mask that uses cameras and filtering to see weld better
[04:46:28] <zeeshan|2> andypugh: how old are you
[04:47:26] <andypugh> Been done. Works wonderfully.
[04:47:42] <zeeshan|2> i use a miller helemt
[04:47:45] <zeeshan|2> mask
[04:47:48] <XXCoder1> oh. I guess still not common due to expense
[04:48:03] <andypugh> zeeshan|2: I think I am 47, but I keep losing count :-)

[04:52:06] <XXCoder1> really best thing to do is just adjust and move on
[04:52:22] <XXCoder1> my back fucked up in my middle 20s

[13:02:18] <zeeshan|2> just to get a feel
[13:02:49] <archivist> small bids sometimes get the item :)

[14:10:22] <humble_sea_bass> this track is crazy
[14:16:02] <PetefromTn_> Suzuka... Interesting. What the hell is that actually some kinda online f1 racing series?
[14:17:10] <humble_sea_bass> yeah. iracing.com -- it is simracing and these guys are beasts at it. I'm still driving the skip barber
[14:19:52] <PetefromTn_> Looks interesting...
[14:21:16] <humble_sea_bass> if you come across a used G25 or 27 racing wheel I suggest you grab it and give iracing a try. I remember you mentioning gokarting with the kids
[14:23:33] <PetefromTn_> haha never seen one of those before.. What do you set it up in your recliner and go F1 racing that is pretty sweet. From the sounds of it there are a bunch of folks racing in there. Do you have to start at the bottom in racing school?
[14:24:20] <PetefromTn_> haha it's got paddle shifters too!
[14:24:21] <humble_sea_bass> they start you with a rookie license and they have a thing called safety rating
[14:24:45] -!- pcw_home has quit [Read error: Connection reset by peer]
[14:24:51] <humble_sea_bass> so you can practice anywhere with any car you own, but you can only do official races which your license allows
[14:25:16] <PetefromTn_> so you gotta buy your cars etc... I bet someone is making some money in this.
[14:25:55] <humble_sea_bass> the more laps/races you complete without incidents (off-road, crash, contact, loss of control) the more SR you gain or lose, at a certain threshhold they upgrade your license
[14:26:21] <humble_sea_bass> you get plenty of fun cars and tracks for the initial subscription
[14:27:00] <humble_sea_bass> like you don't have to buy a new car to progress until you get a C license which is a long long long time out
[14:27:39] <humble_sea_bass> I bought the skip barber for 12 bux i think because it is just a fun fun car and I'm in an unofficial league for skips
[14:27:42] <PetefromTn_> how much is a subscription?
[14:28:09] <humble_sea_bass> for a first time signup you can get it for as little as 8 bux a month

[14:30:25] <PetefromTn_> I LOVE F1 racing and also Grand Prix Motorcycle racing and WSB but if I got one of those wheels and pedals and plugged myself into the TV I probably would never get anything done around here as it is LOL...
[14:31:08] <PetefromTn_> My wife would be beating me with rolling pins to get me off of it I LOVE racing games.

[14:31:59] <PetefromTn_> I remember years ago we bought my kids the first Playtstation 2 system and they had a SWEET F1 racing game. I tried it and before long I looked up and it was the next day and everyone was asleep on the floor around me hehehe
[14:32:02] <humble_sea_bass> Oh I know the feeling
[14:32:37] <humble_sea_bass> "oh guys, i just wanna what its like" *4 hrs later*
[14:32:53] <PetefromTn_> That game was awesome and being a big F1 fan I could not beleive how realistic the track was...
[14:33:24] <PetefromTn_> yeah 4 hours went by quick.... More like a whole day. I have a sickness.....:O

[14:38:10] <PetefromTn_> jeez man that is just nutz... I LOVE monaco I guess they musta lazer scanned that track too.... Nothing like the sound of those F1 monsters screaming thru the tunnel.
[14:39:51] <humble_sea_bass> they don't have the rights for monaco yet last i checked
[14:46:02] <PetefromTn_> sounds like they went to great lengths to laser scan those tracks they do have and spent a whole awful lot of money to do it. No wonder they need to profit from it now with subscriptions.
[14:46:16] <PetefromTn_> I remember one time when I lived down in South Florida.
[14:46:31] <PetefromTn_> I had a good friend who I often rode sportbikes with.
[14:46:41] <PetefromTn_> He worked at Che Fong racing.
[14:47:16] <PetefromTn_> He told me he could use their plastic drag knife machine to make me some custom graphics for my bike I had just repainted.
[14:47:38] <PetefromTn_> So I visited their shop and they had a real serious shifter Kart racing team there.
[14:47:54] <PetefromTn_> I got to drool over their Karts while the mech worked on them sitting on the stands.
[14:48:05] <PetefromTn_> Unobtanium and carbon fiber abounded LOL
[14:48:23] <PetefromTn_> I guess I was drooling so much the mech asked me if I wanted to take a quick ride in one.
[14:48:38] <PetefromTn_> I was like hell I would LIKE to wipe the tires down let alone ride in it..
[14:49:33] <PetefromTn_> He said let me get the brakes bled which he did with a SWEET custom built tall acrylic tube thing that allowed him to see the fluid and pump the brakes and watch the bubbles rise up the tubes.
[14:50:06] <PetefromTn_> Then he had me help him carry it out back to a narrow road that ran behind the industrial park.
[14:50:36] <PetefromTn_> THey had a sorta small track laid out back there and he got in it put on his helmet and gloves and racing shoes and went blasting down that road.
[14:50:52] <PetefromTn_> I about crapped my pants at how fast it was.
[14:51:06] <PetefromTn_> I was used to a 1000CC Yamaha Sportbike.
[14:51:26] <PetefromTn_> He got back and let me take it for a ride after going over the controls and rules etc...
[14:51:40] <PetefromTn_> He said don't try to get over about 120 LOL...
[14:52:03] <PetefromTn_> So I got inside this thing after he adjusted the seat a bit and tried to take off.
[14:52:25] <PetefromTn_> I stalled it initially and he restarted it. I gave it some more gas and let out the clutch and took off.
[14:52:49] <PetefromTn_> I got rolling a bit and tried to give it some gas and OMFG that thing was ridiculous fast....
[14:53:02] <PetefromTn_> I honestly did not have the balls to floor it.

[15:51:51] <IchGuckLive> what size do you need
[15:52:38] <miss0r> I was thinking of buying a large sheet and cut peices my self
[15:52:56] <miss0r> large... hehe nothing larger than 2x2meters
[15:53:15] <IchGuckLive> 60x40cm is the main sheet
[15:53:42] <miss0r> I just have no idea where to get it, I have been searching quite a bit - I think I am calling it the wrong thing
[15:53:51] <miss0r> That will do fine, I can just order a few.

[16:10:08] <tjtr33> for engraving boards try http://www.eplastics.com/POLYCARVE-SIGNBOARD-outdoor-HDPE-sheet or if your in a big city look at signage suppliers like http://www.jfreeman.com/products.html
[16:11:33] <miss0r> I havent yet been able to find a danish supplyer.
[16:12:34] <tjtr33> when i made lithophanes, i needed single color white melamine, and used square dinner plates.
[16:13:17] <tjtr33> miss0r, look for a trophy/engraving business and ask where they get theirs ( they usually make nameplates in 2 colors )
[16:14:00] <miss0r> indeed. I will call someone Monday. I think I've got an idea now :)
[16:14:04] <IchGuckLive> miss0r: pfeister hanover or in Flensburg at Conrad
[16:14:38] <tjtr33> dont limit yourself to melamine unless you have to ( most nameplates i've see are not )
[16:16:37] <IchGuckLive> HDPE
[16:17:15] <PetefromTn_> Huh here in USA when you say Melamine I know it as an industrial sheet particleboard made from wood sawdust and glues that has a very thin layer of plastic skin on it that is typically white. They make cheap ass cabinets from it and often industrial cabinets are made using it and skinned with laminate sheet to make it pretty...
[16:17:58] -!- george2 has quit [Remote host closed the connection]
[16:18:27] <tjtr33> the dinnerware from the 50's was melamine, and Alf was from the planet Melmac :) ( yes melamine verneers are common today )
[16:18:31] <miss0r> that product takes it name from the 'plastic' cover which is made of melamine
[16:20:21] <archivist> but was that just a trade name for what is now known as some generic name
[16:20:23] <PetefromTn_> huh I musta processed a million sheets of that crap and never knew that.... I always just figured it was the particleboard completed called melamine.
[16:20:55] <miss0r> Now you are making me doubt :)

[16:27:26] <tjtr33> and IchGuckLive 's "Graviermaterial" in Deutsche
[16:28:05] <tjtr33> yeah thats what you make name plates with, the cut area is different color because its deeper
[16:28:21] <PetefromTn_> yup
[16:28:23] <CaptHindsight> not good for boat hulls
[16:28:30] <IchGuckLive> every good copy shop got this sheets even good model and hobby stores
[16:28:54] <miss0r> IchGuckLive, I'm not sure we even have 'good' shops in denmark
[16:28:59] <jdh> it's hard to cut well without a flat table and good Z
[16:29:22] <PetefromTn_> whaddya mean good Z?
[16:29:27] <jdh> mine is flat, but not well trammed
[16:30:04] <jdh> my router Z isn't so great. the colored width is Z dependent
[16:30:11] <tjtr33> right
[16:30:40] <tjtr33> PetefromTn_, same problem as your countersink
[16:30:41] <jdh> we have a sign/nameplate maker at work, the cutter floats on the material

[17:22:42] <CaptHindsight> http://www.mds-laser.com/renishaw/circlediamondsquare.html
[17:24:01] <tjtr33> look at the references at end of this http://utwired.engr.utexas.edu/lff/symposium/proceedingsArchive/pubs/Manuscripts/2010/2010-01-Cooke.pdf
[17:24:56] <tjtr33> yeah renishaw ball bar would be nice, or the heidenhain grid, but CDS is free
[17:25:45] <CaptHindsight> heh, their argument is that material is lost :) so not free
[17:26:42] <CaptHindsight> there is no substitute for measuring with actual tools and materials
[17:27:42] <CaptHindsight> but it's a faster way to get a new machine aligned
[17:28:12] <tjtr33> we used it to look for backlash at axis reversal on circle interp
[17:28:30] <tjtr33> backlash/stiffness
[17:29:00] <PetefromTn_> ballbar test is best but that NIST test is interesting. wonder how my VMC would perform in it..
[17:29:09] <archivist> there needs to be an opensource version of that test
[17:29:24] <PetefromTn_> sounds like it is open source no?

[17:29:59] <CaptHindsight> I'd like to see results posted from DIY 3d printers
[17:30:10] <tjtr33> oh (scusa)
[17:30:21] <CaptHindsight> the +- would me in mm
[17:30:24] <PetefromTn_> you can but one and run it yourself but they are NOT cheap LOL..
[17:30:53] <tjtr33> CaptHindsight, use the wooden balbar for carpenter accurate gluegins
[17:32:52] <tjtr33> i think the ballbar is two magnetic ball sockets and an lvdt, likely could make a linuxcnc diy version

[20:11:33] <tjtr33> no need to spin object , no need for background pattern
[20:12:31] <XXCoder2> "low cost"
[20:12:44] <XXCoder2> man we need real low cost scanners.
[20:14:14] <tjtr33> true, its expensive, then it gets understood, then it gets hacked ( CaptHindsight may already have the DLP projector ( major chunk of the monies))
[20:14:36] -!- AR_ has quit [Ping timeout: 240 seconds]
[20:14:51] <XXCoder2> for type iof scanner that uses grid of light to figure shapes?
[20:15:24] <tjtr33> not sure, they dont say much
[20:16:31] <XXCoder2> ok
[20:16:44] <XXCoder2> I wonder if my eyeclops one could be abused for that lol

[20:23:34] <XXCoder2> https://en.wikipedia.org/wiki/Structured-light_3D_scanner
[20:25:38] <tjtr33> i agree it looks like structured light ( project a pattern , look for pattern deformation) http://www.youtube.com/watch?v=Qn5e2Zz2EEM
[20:27:33] <tjtr33> hmmm, scan the Parthenon, push into google Glass in big dark room = holodeck for architecture students, cool
[20:27:34] <XXCoder2> that videos pretty cool
[20:27:44] <XXCoder2> 2 cameras seem to really ramp up accuracy
[20:28:04] <tjtr33> i think they 'stitch' multiple scans
[20:28:11] <XXCoder2> it is.
[20:28:36] <XXCoder2> they rotate newly scanned part till close enough and it auto stitches
[20:29:26] <XXCoder2> https://www.youtube.com/watch?v=c07iM1Unkfk
[20:29:51] <XXCoder2> more facy, its all automated
[20:29:54] <MrHindsight> I get HD DLP's for ~$100 (just the DMD)
[20:30:17] <tjtr33> hehe cant rotate relief carvings on ancient temples http://www.shining3dscanner.com/en-us/case_anguosi.html
[20:30:43] <tjtr33> good deals, my epsons were 200 and i thought i was doing great
[20:31:31] <MrHindsight> I get Epson HD LCD's for ~$70
[20:31:52] <tjtr33> and mibe are not hd ( good enuf for tiny drive in theater )
[20:31:54] <MrHindsight> it looks like structured light, 1 projector and 2 cameras

[20:34:38] <XXCoder2> https://www.youtube.com/watch?feature=player_detailpage&v=ZP8IP8WydAw
[20:34:56] <MrHindsight> so even with off the shelf projectors and cameras ~$1500 in parts with good lenses
[20:35:31] <tjtr33> any open src projects that you'd recommend?
[20:35:54] <MrHindsight> with bargain parts and VGA res maybe $500

[20:45:05] <PetefromTn_> That is some pretty cool stuff. I wonder what the precision of the model is after it is scanned.
[20:45:35] <XXCoder2> from what I see, stuctured light is easiest to do with crappy hardware
[20:45:43] <XXCoder2> webcam and some $100 projector lol
[20:46:40] <PetefromTn_> We got a part in at work yesterday that was a simple arc'd steel bar with bored holes at each end. They had to make another dozen of them to match it. It went on the CMM to get a model to work from but it took awhile. This looks like it is MUCH faster and easier but like I said I wonder how precise the model actually is afterwards.
[20:47:17] <XXCoder2> no idea. probably not percrise enough if you want to accurately repoduce something
[20:47:34] <XXCoder2> its good if you wanna make something like orginial, if not exact

[20:55:12] <XXCoder2> "glass" got screwed up though lol
[20:55:59] <MrHindsight> how well a laser or structured light scanner works has a lot to do how well you put it together...
[20:56:17] <XXCoder2> indeed
[20:56:21] <MrHindsight> just like any other machine, printer, etc
[20:57:10] <XXCoder2> the better projector, camera(s), the better resolution
