[00:10:58] <MrHindsight> sorry my math was way off earlier ~1/50 that of a vacuum gripper
[00:11:45] <MrHindsight> 14.6 psi not 14.6 oz/sq in
[01:35:39] <eren_> Hi All,
[01:36:01] <eren_> I want to use usb to parallel port converter
[01:37:04] <eren_> i don't have parallel port on my pc for that reason I am trying to use usb to parallel port converter
[01:37:51] <eren_> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Parallel_Port_Tester I follow this article
[01:38:17] <eren_> and I connected some leds to parallel port
[01:38:53] <eren_> but when the pins high the leds doesn't work. there is no problem at connections
[01:38:59] <eren_> ı have checked it
[01:39:11] <eren_> Do you think where is my error?
[01:45:27] <MrSunshine> are you sure you do not have a parport? is it a stationary computer ?
[01:48:34] <eren_> no it is a laptop
[01:48:38] <MrSunshine> ahh ok =)
[01:48:56] <MrSunshine> cause i know alot of stationary computers even tho they do not have a parport on the backside can have a header for parport on the mobo =)
[01:49:09] <MrSunshine> sorry and cannot help you with the usb to parport =)
[01:49:32] <smeding> i am no expert, but in my experience USB to parport adapters do not work well for general purpose I/O
[01:49:49] <eren_> ok:D is there another solution to work with linuxcnc?
[01:50:21] <Jymmm> many are using mesa cards
[01:50:33] <eren_> ahh ok
[01:50:39] <eren_> thank you so much
[01:57:12] <Deejay> moin
[02:07:02] <Jymmm> Is that all you have to say for yourself?
[02:15:01] <archivist> eren_, laptops generally dont work, they also have latency problems due to power management
[02:28:40] <smeding> hi there
[02:29:27] <smeding> someone might have asked about this before, but we've inherited an old gantry that we want to attach a plasma cutter to. LinuxCNC seems to handle a lot of the work involved in a neat way, so i'm wondering what the best way to go about this is in general
[02:29:45] <smeding> the gantry has DC motors so the parallel port doesn't seem like a great option (you probably would want PWM, no?)
[02:30:20] <smeding> easiest for us is probably hooking up an AVR or something over serial, would that be a reasonable option?
[02:33:41] <archivist> avr, cough splutter
[02:33:58] <archivist> yes you can do pwm on parallel
[02:34:08] <smeding> is that because of personal microcontroller preferences or is there a reason you don't like AVR
[02:34:19] <archivist> best is use a mesa card for servos
[02:35:24] <archivist> the loop for motor control is in linuxcnc and avr added would be making it hard work
[02:35:32] <archivist> and/an
[02:36:09] <smeding> even if it's just forwarding data?
[02:36:32] <archivist> mesa card has an fpga with the counters etc that make interfacing easy for servo systems
[02:37:16] <archivist> serial is too slow for the control loops
[02:37:48] <smeding> ah
[02:39:04] <archivist> although there is new work for an ethernet connected fpga card
[02:40:00] <smeding> this sounds far more fancy than i'd think we need
[02:40:19] <smeding> i'm surprised serial would be too slow
[02:40:38] <smeding> cheap is probably better than 'just works' for this
[02:41:46] <archivist> parallel port
[02:42:14] <smeding> oh, doh, that's what you mentioned, yeah
[02:44:05] <archivist> there are a number of people with linuxcnc plasma cutters, some have simple stepper drives
[02:44:32] <archivist> there is also a torch height component somewhere
[02:47:20] <smeding> yeah i saw that
[02:47:27] <smeding> i'm not the one running the project, it's a hackerspace thing
[02:47:45] <smeding> someone had an old gantry... it doesn't have 3 axes though
[02:47:52] <smeding> it will probably need some work
[02:48:39] <smeding> might just try no height control for a first revision... i'm having trouble separating "you need this because i've never tried it without" from "you need this because i tried and it doesn't work"
[02:48:43] <smeding> it's not a huge work area
[02:49:29] <archivist> I dont have a plasma, just seen all the others do it in here
[02:50:30] <smeding> i'm only sort of tangentially related to the project, someone else has taken charge a bit more, but i had the time to ask some questions
[02:50:43] <smeding> thanks for the help at any rate, i'll be afk for a bit to make some breakfast
[02:51:02] <archivist> I managed with a couple of manual axes when I started machining so getting away wthout an axis I understand
[02:51:26] <archivist> not had my crumpets yet either
[06:16:57] <LatheBuilder> malcom2073 happy to help
[06:17:40] <malcom2073> LatheBuilder: Found a website that asid it should work heh
[06:22:23] <LatheBuilder> malcom20073 cool. I am hoping to play with 3dp experiments on my mill when it is done. Assuming yours is fdm type?
[06:23:22] <malcom2073> Yeah it is
[06:36:20] <malcom2073> LatheBuilder: http://jv4779.blogspot.com/search?updated-min=2011-01-01T00:00:00-08:00&updated-max=2012-01-01T00:00:00-08:00&max-results=2
[06:42:18] <LatheBuilder> ever heard of metal injection molding, or the craft world equivalent "metal clay"?
[06:42:57] <malcom2073> I've not
[06:43:05] <malcom2073> Though I'm not up to speed on injection moulding technology :)
[06:46:16] <LatheBuilder> think metal powder mixed with just enough binder to make it flow like melted plastic. debinding and sintering the finished product yields fully dense metal parts with repeatable shrinkage. Many firearm parts are made with MIM. Fertile ground for fdm territory. Wouldn't it be cool to directly print metal parts on your 3dp? With some finish work admittedly
[06:46:44] <malcom2073> Hmm cool
[06:47:02] <malcom2073> I've seen someone did a wlding printer, which used welding bead to "build" up the part, and then milling to fine-hone it to the shape needed
[07:02:17] <LatheBuilder> Have seen those as well. I imagine pretty high internal stresses in those parts.
[09:04:37] <humble_sea_bass> also anisotropic
[09:12:32] <Loetmichel> soo, fuckup repaired... just took half the time of making a new part... -> http://www.cyrom.org/palbum/main.php?g2_itemId=14844
[09:13:03] <MrHindsight> LatheBuilder: the % of solid metal is much higher with injection molding than with any resin
[09:15:16] <MrHindsight> LatheBuilder: printing them with FDM and with a resin metal powder would be the slowest and lowest res way to make those parts besides maybe starting from a cast block and sanding them into shape
[09:18:01] <_methods> when all you have in your box is a hammer...........
[09:18:24] <LatheBuilder> mrhindsight: ya, I'm not suggesting that craft class metal clay will make parts near as well as MIM done with appropriate binder selection. I just wish the feedstock wasn't so expensive.
[09:20:30] <MrHindsight> depending on the size and detail of your parts printing a lost wax casting or resin/metal and SLA/DLP
[09:20:44] <LatheBuilder> _methods all your problems look like nails. =)
[09:21:03] <_methods> indeed
[09:21:22] <_methods> omg look at this bit of genius
[09:21:24] <_methods> http://www.foodiggity.com/the-chicken-pot-pie-cone-for-on-the-go-comfort-eating/
[09:23:53] <MrHindsight> the KFC version will be similar only in a paper cone to lower the amount of ~food yet keep the same size
[09:24:10] <_methods> heheh
[09:24:18] <_methods> the cone will be made from fried chicken
[09:24:43] <malcom2073> And have a layer of cheese on the inside
[09:24:49] <MrHindsight> or batter to lower the cost to make
[09:25:06] <_methods> hmmm i'm starting to like the sound of this kfc one more
[09:25:27] <_methods> cheese, friedchicken, batter chicken pot pie
[09:26:15] <MrHindsight> the masters of packaging as little ~food as possible into the greatest space
[09:26:39] <LatheBuilder> "Their only problem, is that it can be a bit challenging to eat them on the go, or in the shower". I always wish I could eat a chicken pot pie when I shower!
[09:26:57] <_methods> hahah
[09:27:27] <MrHindsight> I stopped since I'd forget which hand had the soap and which the pie
[09:27:38] <_methods> ah gawd
[09:28:26] <MrHindsight> LatheBuilder: http://www.3ders.org/articles/20140415-ecn-uses-new-dlp-technology-for-3d-printing-metals.html
[09:28:37] <LatheBuilder> and I as well. too many vegetable burns.
[09:28:40] <ubu_> hi everyone
[09:28:49] <ubu_> hi MrHindsight
[09:28:54] <LatheBuilder> hi ubu_
[09:29:58] <MrHindsight> LatheBuilder: DLP printers with a high wax resin can make molds for burnout in minutes
[09:30:39] <ubu_> I use cut 2d 10mm pocket square, but looked 9.1mm on emc2's screen.why?
[09:30:55] <LatheBuilder> MrHindsight and that is as high res as you could want. Nice find.
[09:31:17] <jdh> did you click 'outside' in cut2d?
[09:31:33] <jdh> or not... right tool diameter?
[09:33:16] <LatheBuilder> MrHindsight: have a formula you are willing/able to share?
[09:33:18] <ubu_> no,, pocket offset.
[09:33:28] <ubu_> not have out/inside
[09:33:38] <MrHindsight> LatheBuilder: for which app?
[09:34:11] <jdh> oh yeah. nevermind.
[09:34:17] <LatheBuilder> MrHindsight: high was resin for DLP curing
[09:34:26] <ubu_> I will do calibration, but my draw : 10mm, emc screen : 9.1mm, job :9,3 mm
[09:34:27] <ubu_> :)
[09:34:42] <jdh> I use cut2d + linuxcnc all the time. It works great.
[09:34:43] <LatheBuilder> MrHindsight: high wax resin for DLP curing, rather. typo corrected
[09:35:07] <ubu_> yeah jdh , very nice.
[09:35:14] <ubu_> how I do this calibration?
[09:35:35] <archivist> ubu_, did you set the right tool size
[09:36:02] <ubu_> yes,tool is right, I will check again now.
[09:36:03] <jdh> if it is actually cutting small, you have the wrong tool size selected or your linuxcnc scale is wrong
[09:36:04] <LatheBuilder> ubu_ does the tool diameter in lcnc match the real tool diameter you are using?
[09:36:37] <jdh> if you draw a 10mm pocket, the toolpath will be 10mm - tool-diameter
[09:37:47] <MrHindsight> LatheBuilder: http://www.google.com/patents/US5391460
[09:37:48] <_methods> http://cnc25.free.fr/documentation/programmation_en/crc1.gif
[09:41:06] <ubu_> I draw new
[09:41:52] <ubu_> I guess, best way calibration,make pocket
[09:42:36] <jdh> best is to just hand code a rectangle
[09:42:49] <LatheBuilder> MrHindsight: Thanks!
[09:42:58] <jdh> or measure with a dial indicator
[09:44:43] <ubu_> first I use, digital compas.
[09:44:58] <_methods> wut?
[09:45:21] <_methods> i hope that is some lost in translation shit
[09:45:43] <LatheBuilder> perhaps ubu_ means digital calipers?
[09:45:56] <_methods> i hope so
[09:46:25] <ubu_> yes yes :)
[09:46:27] <jdh> 10mm, north... same thign.
[09:46:32] <ubu_> digitall calipers
[09:46:36] <_methods> whew
[09:46:57] <ubu_> I do gcode, but , emc2 screen 9.1mm again, what wrong?
[09:47:10] <_methods> pastebin your code
[09:47:10] <jdh> are you using a 4.5mm end mill?
[09:47:51] <jdh> or rather, did you tell cut2d you were using a 4.5mm cutter?
[09:48:02] <ubu_> no 0,9mm end mill
[09:48:12] <_methods> ok
[09:48:14] <_methods> it's cutter com
[09:48:22] <jdh> yeah, that's what I really meant.
[09:48:28] <jdh> 4.5, .9... close enough.
[09:48:35] <_methods> .045 lol
[09:48:41] <_methods> .0045
[09:48:48] <ubu_> maybe ,linuxcnc tool table wrong?
[09:49:01] <ubu_> very thin mill
[09:49:36] <ubu_> my gcode is http://paste.ubuntu.com/7330182/
[09:50:09] <ubu_> emc2 arcs mm postscript.
[09:50:30] <jdh> a that's a tiny cutter
[09:50:43] <MrHindsight> LatheBuilder: http://www.google.de/patents/US4844144 http://www.google.de/patents/US5176188
[09:51:27] <jdh> to cut 10mm with a .9mm cutter, you travel 9.1mm
[09:52:30] <ubu_> finish job is 10mm ok?
[09:52:46] <jdh> right
[09:53:06] <_methods> oh he used the center of the pocket as 0,0
[09:53:48] <_methods> k pocket passes
[09:54:02] <ubu_> thanks all
[09:54:12] <ubu_> I'm wrong:)
[09:54:29] <ubu_> sorry
[09:54:40] <_methods> so no cutter comp in program
[09:54:45] <_methods> he did it all in software
[09:54:46] <MrHindsight> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Simple_LinuxCNC_G-Code_Generators#Rectangular_Circular_Pocketing_Generator
[09:54:48] <jdh> if your final cut dimensions are wrong your axis scales are wrong or tool diameter isn't what you think it is.
[09:55:03] <_methods> and you can't fix it since you dind't use cutter comp
[09:55:24] <jdh> it's trivial to recam this though.
[09:55:29] <_methods> yeah
[09:55:34] <_methods> lol
[09:55:38] <_methods> indeed
[09:55:52] <MrHindsight> ubu_: try the generator for comparison
[09:56:32] <MrHindsight> how do you guys cut those square corners?
[09:56:36] <ubu_> I looking now
[09:56:43] <ubu_> MrHindsight:
[09:56:44] <_methods> hehe
[09:56:47] <_methods> with a chisel
[09:57:06] <ubu_> which best way calibration, digital caliper or profile job or pocket job or generator?
[09:57:06] <archivist> file/broach
[09:57:17] <archivist> depends
[09:57:43] <humble_sea_bass> you don't have an EDM in your shed?
[09:58:13] <MrHindsight> does Linuxcnc have broaching? hold a broach move Z up and down
[09:58:29] <_methods> lol
[09:58:52] <MrHindsight> humble_sea_bass: I keep it in the the shower next to the microwave
[09:59:24] <LatheBuilder> and the chicken pot pies
[09:59:30] <_methods> hahahahhahahah
[10:00:59] <LatheBuilder> =)
[10:01:30] <MrHindsight> http://www.fopat.com/index.php?page=new-foam-pattern-material
[10:04:09] <LatheBuilder> mrhindsight: that looks promising. thanks for the links!
[10:05:25] <LatheBuilder> I can't tell from my end, are usernames case sensitive on irc?
[10:05:52] <humble_sea_bass> they are not
[10:06:10] <MrHindsight> just some of the users
[10:07:40] <LatheBuilder> thanks humble_sea_bass. good to know MrHindsight =)
[10:20:55] <ubu_> 3d printing very funny, but difficulty
[10:21:23] <_methods> you summed that one up
[10:21:37] <ubu_> I draw 10mm square profile on cut 2d. emc2 screen 10mm is ok.
[10:21:46] <ubu_> thanks dearly friends.
[10:27:03] <ubu_> I don't linuxcnc camera
[10:27:19] <humble_sea_bass> Prog rock friday, or reggae friday?
[10:27:43] <jdh> no hiphop?
[10:28:37] <humble_sea_bass> on a friday? never
[10:29:11] <humble_sea_bass> not till 5PM when Afroman gets played as a goodbye song
[10:29:16] <ubu_> jdh: do you use cnc camera? psha.
[10:55:55] <ubu_> MrHindsight: , Is there anything else I should do? on camera?
[10:58:58] <_methods> hehe
[10:58:59] <archivist> ubu_, you need to ask better questions, how can we know what your problems are
[10:59:22] <_methods> and what you do on camera is private
[10:59:30] <ubu_> archivist: my grammar is very bad , sorry
[10:59:46] <ubu_> linuxcnc camera and camunits
[11:00:58] <archivist> not a grammar problem, it is no real question problem
[11:03:12] <malcom2073> heh
[11:03:27] <ubu_> problem is solved some
[11:04:18] <ubu_> I plug camera on cnc, but not open. I work other ways.
[11:04:53] <ubu_> now ok , but linux froze :)
[11:12:42] <MrHindsight> ubu_: we tried that install yesterday, we have the camera in the window but the extensions are broken
[11:13:01] <MrHindsight> I'll have to fix it in the near future
[11:17:09] <MrHindsight> his camview howto cleverly leaves out the details on editing the Linuxcnc configs to make it all work
[11:18:19] <MrHindsight> installing the repos and the packages does work, but that's as far it goes, no edits to linuxcnc configs
[11:21:39] <ubu_> I don't like cnccamera
[11:22:02] <ubu_> We install other camera program
[11:22:47] <ubu_> separately use
[11:23:23] <MrHindsight> I think it's better if the camera is in its own window vs a tab
[11:23:56] <MrHindsight> I want to see the camera and the position without an overlay
[11:24:40] <MrHindsight> camera view with simulation overlay would be good for preflight
[11:25:01] <MrHindsight> see what you are going to hit before you hit it :)

[11:55:31] <Jymmm> "Like a 3D Printer, it can chisel away..." *sigh*
[11:55:58] <MrHindsight> at your wallet
[11:56:25] <Jymmm> It's a nanorouter, nottttt a 3D fucking printer!
[11:57:34] <archivist> have to use teh right buzz words to get high in the search ranking
[11:57:46] <Jymmm> sadly, yes
[11:59:14] <MrHindsight> and it has an iphone app :)
[11:59:17] <Jymmm> But now I think that just took away some brownie points for doing that in no research was done nor fact verification.
[11:59:51] <MrHindsight> #nota3dprinter
[11:59:57] <Jymmm> lol
[12:00:46] <Jymmm> Man, I like this fishing pole I got even thugh I'm not going to use if for fishing, but now I just might! lol
[12:01:03] <Jymmm> 15" collapsed, extends to 14ft
[12:01:08] <MrHindsight> ocean fishing?
[12:01:18] <Jymmm> Heh, Nooooooooo
[12:01:42] <Jymmm> It's a panfishing pole, but I got it to use as a mast for y rollup antenna
[12:02:09] <Jymmm> s/y/a/
[12:02:33] <MrHindsight> panfishing? you lure them in close enough to whamoo with a pan or?
[12:04:40] <Jymmm> I got it for $20 shipped on sale http://www.cabelas.com/product/Cabelas-Telescopic-Panfish-Poles/738690.uts?Ntk=AllProducts&searchPath=%2Fcatalog%2Fsearch.cmd%3Fform_state%3DsearchForm%26N%3D0%26fsch%3Dtrue%26Ntk%3DAllProducts%26Ntt%3Dpanfish%2Bpole%26x%3D0%26y%3D0%26WTz_l%3DHeader%253BSearch-All%2BProducts&Ntt=panfish+pole&WTz_l=Header%3BSearch-All+Products

[12:11:03] <micges> asah: hi
[12:11:18] <micges> asah: did you figure out hm2_eth problem?
[12:11:55] <IchGuckLive> hi all B)
[12:15:01] <IchGuckLive> Loetmichel: heavy thunder overhead but no rain
[12:15:22] <IchGuckLive> itas a miss we are about 170liters short for this month
[12:50:26] <humble_sea_bass> i've got it
[12:50:36] <humble_sea_bass> 3D printed fishing line, i'll make millions
[12:51:57] <Jymmm> I'll buy and resell from china and underbid you by 40%.... PROFIT!
[13:16:33] <malcom2073> lol
[13:17:44] <CaptHindsight> and if the fishing line can be used as filament on smaller FDM printers that opens a whole other market
[14:19:35] <humble_sea_bass> http://www.theonion.com/articles/study-finds-owning-cool-leather-jacket-more-reward,27627/
[14:24:09] <malcom2073> I agree.
[14:24:35] <malcom2073> Oh, didn't read the whole title
[14:24:36] <malcom2073> lol
[15:29:52] <LatheBuilder> MrHindsight: Panfishing >> fishing intentionally for small freshwater fish shaped flat like a pan. Panfishing poles are light weight to make catching them more fun. They are tasty and fight like fish much larger.
[15:33:30] <PetefromTn_> Well I got my General Tap handles and some other tools today. Very pleased with them. got a new Starrett Edgefinder too. My LED edgefinder was just not cutting it. Waiting on a couple other tools I ordered.
[15:34:15] <LatheBuilder> nice PetefromTn_
[15:34:25] <PetefromTn_> Yeah I kinda think so LOL
[15:34:53] <PetefromTn_> I was quite surprised at the difference in quality of the Tap handles over what I have been using that I THOUGHT were nice.
[15:35:35] <PetefromTn_> I also received a new 60 degree dovetail cutter finally so I can machine the scope mounts I am working on properly.
[15:35:39] <LatheBuilder> always a nice jump to make. Makes ya wish you placed the order sooner.
[15:35:59] <PetefromTn_> yeah but money is all it takes...usually a LACK of that around here LOL
[15:36:07] <LatheBuilder> need to make angle mounts for hipower?
[15:36:49] <PetefromTn_> No actually I am working on an elegant looking Custom mount for a precision Competition Air rifle for a customer and if it works out well I am gonna make them to sell.
[15:36:56] <LatheBuilder> high power as in long dist rifle, not browning hipower
[15:37:25] <LatheBuilder> Right on
[15:37:48] <LatheBuilder> precharged pneumatic?
[15:37:54] <PetefromTn_> yeah. PCP
[15:38:06] <PetefromTn_> FWB P series
[15:38:36] <LatheBuilder> ...ya, I spelled it out for the first mention so nobody would get the wrong idea what wee were talking about?
[15:39:27] <PetefromTn_> understood.
[15:39:36] <LatheBuilder> feinwerkbau, good taste
[15:40:42] <PetefromTn_> Yup but unfortunately I cannot afford one LOL...
[15:41:05] <LatheBuilder> Nor I. I hear you there. Day job gunsmith, or machinist?
[15:42:15] <PetefromTn_> Well currently I am working as a machinist in a local Job shop but on TV I run my own shop making cool parts for customers.
[15:43:02] <PetefromTn_> Right now trying to swing a new quality milling vise for the VMC. Not terribly happy with my CNC vise.
[15:45:21] <LatheBuilder> I can relate on both counts. Day job mechanical engineer designing automation and robotic tooling. Nights and weekends have a small shop (just me).
[15:46:07] <PetefromTn_> Ooh that at least sounds like interesting work.
[15:46:19] <LatheBuilder> My control broke just as I was getting into the swing of it.
[15:47:09] <PetefromTn_> I would love to machine some cool parts for automation and robotics companies or prototypes my machine is certainly capable of it.
[15:47:27] <PetefromTn_> Make money creating cool stuff. Enjoy doing what you do...
[15:48:59] <LatheBuilder> Nothing to complain about here. Originally started building my shop to make my own stuf, quit my projects to take on outside work. Decided I hated doing outside work and when the control on my vmc broke it was a good split. Now fixing it to work on my own projects exclusively.
[15:49:26] <LatheBuilder> What do you have in the way of machines?
[15:50:05] <PetefromTn_> http://imagebin.org/307482 Here's my scope rail thus far... Got four of them made just gotta cut the dovetails.
[15:50:21] <PetefromTn_> I have a Cincinatti Arrow 500 VMC with LinuxCNC Retrofit...
[15:50:44] <PetefromTn_> I also have a decent asian lathe 12x36 that works well but I am trying to get the funds up for a CNC lathe purchase.
[15:51:24] <LatheBuilder> Nice part.
[15:51:46] <LatheBuilder> Mesa hardware on the Cinci?
[15:52:28] <PetefromTn_> Yeah that is actually the first one I made and then realized it did not have enought headroom for the dovetails with built in droop I wanted so it is now slightly taller in that area with the following four I made.
[15:52:39] <PetefromTn_> yeah Mesa..Excellent stuff so far.
[15:54:12] <PetefromTn_> Been making parts in soft jaws almost exclusively since I got the CNC vise and then the Other day tried to setup the part to cut the dovetails and realized the bed is not flat on the vise.
[15:54:31] <PetefromTn_> Took it out of the machine and put it on my granite plate and checked it.
[15:54:50] <PetefromTn_> Shows it is out by .0007 across the width.
[15:55:12] <PetefromTn_> Checked it with a mic from bottom of vise to bed rail top and it confirms it.
[15:55:20] <PetefromTn_> Really kinda pissed about that.
[15:55:42] <PetefromTn_> I did not expect perfection from a cheap vise but I DID expect it to at least be flat across the damn bed.
[15:55:44] <LatheBuilder> have the same problem on my two cheap kurt knockoffs. They have raised lips along an edge/corner.
[15:56:01] <PetefromTn_> Funny you say that it is not the whole bed on mine either.
[15:56:06] <PetefromTn_> It is near the edge.
[15:56:23] <PetefromTn_> Not just the lip of the edge but gradually rises up near the edge.
[15:56:43] <PetefromTn_> I ALMOST took a flycutter to it the other day.
[15:56:47] <PetefromTn_> I was so pissed.
[15:57:12] <PetefromTn_> The place I am temporarily working told me I could bring it in and grind it flat for free.
[15:57:29] <PetefromTn_> But unfortunately when I looked at their griding machines it is not possible.
[15:57:52] <PetefromTn_> They have a HUGE blanchard grinder which would work perfect if it was a removable fixed jaw like a kurt.
[15:58:05] <LatheBuilder> flycutter is in store for mine. If you tear it down farther will it fit?
[15:58:14] <PetefromTn_> But alas it is a CNC style that has the more rigid assumably built in fixed jaw.
[15:58:44] <Deejay> gn8
[15:58:52] <PetefromTn_> Their bank of surface grinders even the big one does not have enough throat to grind up to that face and still reach the end of the vise ways.
[15:58:55] <LatheBuilder> nite Deejay
[15:59:07] <PetefromTn_> NITE MAN!!
[15:59:57] <PetefromTn_> whaddya mean tear it down farther?
[16:00:22] <LatheBuilder> was thinking it was a bolt on back jaw
[16:01:13] <PetefromTn_> Honestly it really sucks because OTHER than that problem I was fine with the vise and was considering getting another one.
[16:01:23] <PetefromTn_> what vises do you have?
[16:01:51] <LatheBuilder> how about doing it in two halves and leaving an intentional ~.001 gulley in the middle say half an inch. Still plenty of clamping surface left I bet.
[16:02:15] <PetefromTn_> Ya know that is not a terrible idea...
[16:02:21] <LatheBuilder> ENCO specials. Do not recommend, though I bought them over a decade ago
[16:02:25] <PetefromTn_> The grinding wheel is only maybe 3/8 wide...
[16:02:47] <LatheBuilder> enough throught to get close to half way?
[16:03:26] <PetefromTn_> If there was a small difference in height between the grinds it would only be a problem in a very small percentage of clamping situations at all...
[16:03:50] <PetefromTn_> Or rather not difference in height between the grinds but the gap I should have said.
[16:04:02] <PetefromTn_> The grinds need to be perfect.
[16:04:35] <PetefromTn_> They told me they had an older Kurt that was not that great and they ground it but it was not a permanent fixed jaw like this one.
[16:05:04] <LatheBuilder> maybe I have the wrong type in my head. Are you talking vertical spindle blanchard, or horizontal spindle surface grinder?
[16:05:07] <PetefromTn_> I was really looking forward to getting ANOTHER CNC vise and having them ground to be matched pair so anything I do on the table would be exactly the same.
[16:05:19] <PetefromTn_> They have both.
[16:05:41] <PetefromTn_> The big Blanchard grinder is a MONSTER but only make flat parts flat.
[16:06:00] <PetefromTn_> The surface grinders are smaller and more like a mill with a horiz spindle and moving table.
[16:06:08] <PetefromTn_> Typical surface grinders.
[16:06:25] <PetefromTn_> that Blanchard I cannot even guess what that monster weighs.
[16:06:30] <PetefromTn_> It is a beast.
[16:06:54] <LatheBuilder> bought several blanchard ground plates for machine bases. can't fit one of those in the garage but wouldn't mind a surface grinder with a mag chuck and a spin fixture
[16:07:32] <PetefromTn_> Yup they have a bank of several of those at work. Nice machines. Even a slightly worn one can be made to make some real nice parts flat with.
[16:08:11] <PetefromTn_> One of the guys is very skilled with them and he gets all the real critical stuff. Makes them look almost polished....beautiful work.
[16:08:55] <PetefromTn_> I would not mind having one here in my shop but they made a mess....
[16:09:02] <PetefromTn_> make
[16:09:44] <LatheBuilder> Nice. make more mess than a full size laser cutter? That stuff gets everywhere
[16:11:14] <LatheBuilder> Didn't notice it at one place I worked until we moved something and realized the monitors were not beige but cream. 8' x 10' 2kw
[16:11:15] <PetefromTn_> Dunno the only fullsize laser cutter was in a friends shop I have ever seen. That was a sweet machine. They went out of business recently and all the machines were liquidated.
[16:12:19] <LatheBuilder> sorry to hear your friends shop went bust.
[16:12:22] <PetefromTn_> I did have them make me some sweet heavy gauge stainless way guards for my old RF45 tho. They cut them and engraved them in the same operation.
[16:12:32] <PetefromTn_> Yeah I was too they were cool guys.
[16:12:49] <PetefromTn_> I used to drop by and visit and they would sell me materials for good prices.
[16:13:16] <PetefromTn_> Used to chat about what they were working on and how they fixtured stuff up. Learned a lot from those guys.
[16:14:08] <LatheBuilder> ever use cerrosafe to fixture up something like a thin wall tube for machining?
[16:15:44] <LatheBuilder> old time machinist from a research hospital machine shop showed me that trick. Melts in boiling water
[16:16:18] <LatheBuilder> they used it for fixturing things that were too weak to clamp any other way, but still needed cut.
[16:18:51] <PetefromTn_> I have heard of some adhesives that work that way but have never used them before. I have used carpet tape before tho on thin aluminum parts tho. Worked better than expected.
[16:21:07] <LatheBuilder> I know, right? who knew fiberglass carpet tape would hold so well.
[16:22:07] <LatheBuilder> in your Cinci, did you go 5i20 or 5i25? Or perhaps something else entirely?
[16:22:24] <PetefromTn_> 5i25 7i77
[16:24:56] <LatheBuilder> To build your first lcnc config for them (same ones I have) did you use pncconf, or start from a sample and hack through it until it worked?
[16:26:32] <PetefromTn_> Well we started with PNCconf but moved on once the basic machine was working to add stuff.
[16:27:06] <PetefromTn_> Still have not gotten to the toolchanger need to get spindle orientation working first and have not gotten around the making the encoder mount yet. Life gets in the way sometimes.
[16:27:20] <PetefromTn_> I do use the machine all the time tho when I am not working in the other shop.
[16:27:44] <LatheBuilder> what version of lcnc? I hear you on "busy"!
[16:27:54] <LatheBuilder> (three kids, all young)
[16:28:02] <PetefromTn_> This summer my kids will be off from school of course and I THINK I will be taking a leave of absence to be with them and also to get the shop going some more.
[16:28:11] <PetefromTn_> I have two kids and two stepkids.
[16:28:20] <PetefromTn_> So yeah it can get BUSY.
[16:28:59] <PetefromTn_> Altho I am making progress to get the shop as well as the machine ready to work in a better manner.
[16:29:07] <PetefromTn_> Buying tooling and tools holders etc.
[16:29:41] <PetefromTn_> Thought I was gonna have to pay this year on my taxes but wound up not having to so that helped a bit.
[16:31:03] <LatheBuilder> 2.5.x? I couldn't dig up the xml file for 5i25 7i77 in 2.5.4 so upgraded to 2.6. Doesn't seem to work in 2.6, though pncconf does at least recognize the cards.
[16:32:12] <LatheBuilder> tooling budget sure likes having a tax refund
[16:32:27] <PetefromTn_> I went with master in the latest build as of about a month ago but they just came out with 2.6 so no idea.
[16:32:38] <PetefromTn_> Yeah I am getting a refund but not a big one.
[16:32:51] <Tom_itx> what was that android irc client you tried?
[16:32:51] <PetefromTn_> I MIGHT buy a kurt vise with it.
[16:33:03] <PetefromTn_> who me?
[16:33:40] <Tom_itx> i think so
[16:33:54] <PetefromTn_> I use Andchat on my Android phone.
[16:34:01] <PetefromTn_> Works pretty damn good so far.
[16:34:32] <Tom_itx> you like it?
[16:34:43] <LatheBuilder> (looks like i need to switch to master)
[16:34:45] <PetefromTn_> I would say so yeah...
[16:34:58] <Tom_itx> what phone?
[16:35:27] <PetefromTn_> I have an older phone here.
[16:35:32] <PetefromTn_> It is an LG G2x
[16:35:45] <PetefromTn_> I need to upgrade but it keeps working well so I have not.
[16:35:58] <Tom_itx> i upgraded from a flip
[16:36:20] <PetefromTn_> My stepdaughter bought one of those newer smartphones I think it is an HTC one...
[16:36:40] <Tom_itx> i got a Galaxy S4
[16:36:45] <Tom_itx> the S5 is way too big
[16:37:31] <PetefromTn_> She now wants to switch to another server and we were talking about me buying her phone out and use it and sell my LG G2X
[16:37:52] <Tom_itx> the speech to txt seems pretty good on it
[16:37:54] <PetefromTn_> That phone she has it quite a bit larger than mine which I think I would like.
[16:38:10] <PetefromTn_> Yeah my wife and daughter have the Galaxy S4's...
[16:38:14] <Tom_itx> the camera is excellent
[16:38:21] <PetefromTn_> agreed.
[16:38:39] <PetefromTn_> Hard to believe how far we have come...
[16:38:40] <Tom_itx> still like my Nikon
[16:38:56] <PetefromTn_> I remember when a cell phone was a huge brick and only the wealthiest have them
[16:39:09] <PetefromTn_> Now my 12 year old daughter has a smartphone.
[16:39:20] <Tom_itx> i had a brick
[16:39:40] <PetefromTn_> well you musta been a big wig or something LOL.
[16:39:54] <Tom_itx> before that i recall an aquantance with a bag phone
[16:40:03] <Tom_itx> no not really
[16:41:41] <PetefromTn_> my dad had a bag phone in his corvette back in the day. 1986 I think....
[16:42:00] <PetefromTn_> Then he said he did not like it and had a permanent phone installed in the car.
[16:42:35] <PetefromTn_> I remember calling my mom to tell her we were coming home from a soccer practice driving with my dad with the targa top out thinking how cool we were LOL...
[16:42:53] <PetefromTn_> Good old days...
[16:44:09] <PetefromTn_> I got the Starrett singe edge finder this time over that two ended one I sold with the RF45 like a jackass..
[16:44:53] <PetefromTn_> I have been using one of the guys at work and I found the action on the single ended one I like better for some reason. Hopefully the one I got here in the mail today works similarly.
[16:45:34] <PetefromTn_> I never really understood the pointy end that much.
[16:46:08] <PetefromTn_> You would have to know exactly the depth you went from the surface to determine the angle to find the offset to use once you located the edgte.
[16:47:02] <PetefromTn_> I used to put it in the hole and then CAREFULLY jog down until it was seated and then adjust X and Y until the body was centered to located holes sometimes. I know not how you are supposed to use it.
[16:47:37] <PetefromTn_> But locating the center of parts from each side it would be nice if you cannot fit the square end one in there.
[16:47:56] <PetefromTn_> I figure I will just use my DTI for that.
[16:51:03] <Loetmichel> cradek: seen the repair?
[16:59:05] <PetefromTn_> http://nashville.craigslist.org/tls/4431072176.html Not a terrible deal...
[17:18:07] <andypugh> Hi chaps.
[17:18:22] <andypugh> Not been about much, I have been busy with my Ner-a-Car
[17:19:25] <andypugh> I made a rivet-squeezer which worked out pretty well. Last night I re-assembled the chassis. 70+ rivets. I am glad I wasn’t doing that by hand.
[17:20:03] <andypugh> My rivet squeezer: http://bodgesoc.blogspot.co.uk/2014/04/hydraulicrivetsqueezer.html
[17:20:31] <andypugh> A _real_ rivet squeezer: http://www.practicalmachinist.com/vb/antique-machinery-history/hydraulic-riveter-111732/
[17:24:50] <jdh> that's a funky looking bike
[17:25:19] <skunkworks_> andypugh: neat!
[17:32:13] <PetefromTn_> Nice man... How did you cut that c shaped part?
[17:33:28] <_methods> +alex_joni
[17:33:59] <_methods> oops sorry
[17:34:31] <andypugh> PetefromTn_: I didn’t have any material, and at that point I have found that rather than buy the material it’s nearly as cheap to send a dxf to the local laser cutting co.
[17:37:18] <PetefromTn_> I was wondering I know you could probably make it but it would take awhile LOL.. Looks nice tho. Solid rivets are STOUT....
[17:37:38] <skunkworks_> andypugh: did you see http://bbs.homeshopmachinist.net/threads/63198-Electronic-Gear-Hobber?highlight=electronic
[17:37:44] <PetefromTn_> I thought I saw someone use an air hammer setup to install them at one point.
[17:37:47] <skunkworks_> was that you that helped the help?
[17:39:20] <andypugh> Hmm, he has asked me for advice, then not deigned to reply. Twice.
[17:39:33] <skunkworks_> andypugh: odd
[17:39:46] <andypugh> (JS, that is)
[17:41:26] <andypugh> I am actually confused, because I definitely am the chap that the second post refers to. All I can assume is that my replies had all the required info…
[17:44:03] <PetefromTn_> Well ya see there you were such a helpful fellow he did not even need to get back to ya...what a jackass.
[17:45:45] <andypugh> I do wonder if he sees me as a threat to his “most expert” crown.
[17:47:05] <PetefromTn_> perhaps he is not wanting his THUNDER stolen....
[17:48:00] <PetefromTn_> Just texted a chap in West Knoxville that is selling a bunch of machining tooling and tools. Gonna head over there after dinner and check out what he has for sale. Hoping for some great deals on good tooling and measuring tools.
[17:48:36] <andypugh> PetefromTn_: I think you can set rivets with an air hammer, but it needs to be quite a big one, and they need to be backed-up well.
[17:50:36] <andypugh> A lot of these rivets had really tight access to the back: https://picasaweb.google.com/lh/photo/qZ-CWLk7HEVogw_4jz6suNMTjNZETYmyPJy0liipFm0?feat=directlink
[17:52:04] <andypugh> And it was handy to take the rivetter to the chassis, not the chassis to the rivetting dolly: https://picasaweb.google.com/lh/photo/CtGYt6s76gjzdxqgV6OMGdMTjNZETYmyPJy0liipFm0?feat=directlink
[17:53:30] <andypugh> (I need more space, I have the workshop and two bikes in a single garage)
[17:53:35] <PetefromTn_> I am sure man... I think it can be done tho. I THOUGHT the guy used a heavy duty pneumatic impact hammer and fashioned a special anvil shaped the way he needed and then had it hardened. As far as the backing up yeah that is another story I am sure. Needs to be done against an anvil or something but your solution is MUCH prettier.
[17:54:11] <PetefromTn_> What I don't understand is what do you need this NERACAR for when you have an R1 LOL...
[17:54:14] <andypugh> Quieter too. Which was an advantage at midnight last night, in a residential area.
[17:54:35] <PetefromTn_> yeah I am sure the impact would make a helluva racket.
[17:55:33] <PetefromTn_> I remember building my Suzuki samurai Rock crawler in the driveway of our last house I had to grind a bunch of rivets and welds off the frame of the front shock mount and it made a HELLUVA noise. I am sure my neighbors were cursing me that day.
[17:57:12] <andypugh> It’s a complete fluke that the C-frame tightens up exactly aligned with the pump handle :-)
[19:12:19] <Tom_and> Wonder why I couldn't use my regular Nick
[19:42:49] <somenewguy> question on putting a 4th axis on my mill
[19:43:00] <Meduza> yes?
[19:43:04] <somenewguy> what is the typical sign conventionand axis naming?
[19:43:33] <somenewguy> obviously I can doit however I want, but if there is a "normal" way of doing it Id rather try and coform
[19:43:56] <somenewguy> like should A rotate normal to X travel or Y travel etc
[19:43:56] <Meduza> If the 4th is a classic rotary axis mounted in paralell with the X axis i would call it a A axis
[19:44:15] <Meduza> on a classic mill type machine
[19:44:19] <somenewguy> ok
[19:44:39] <somenewguy> so traveling in the X direction would move you towards or away from the face of the rotary plate
[19:44:44] <somenewguy> if it were the A axis
[19:45:07] <somenewguy> I would take it B would be off the Y and C off the Z?
[19:45:35] <somenewguy> notthatthethird location would actually add any utility to a cnc mill
[19:46:10] <Meduza> yeah
[19:48:47] <somenewguy> ok cool
[19:49:59] <somenewguy> now I just need to find my stash of DE-9 connectors and I'll have a 4 axis mill
[19:50:30] <somenewguy> just got some din rail so I can actually mount my misc components inside my controls box, good by zip ties, hello almost professional looking
[19:57:28] <jdh> machine built wheels. I think the rim tape is manual though
[19:58:02] <jdh> <urk>
[20:01:41] <andypugh> jdh: I can’t help speculating. Machine-built sounds like bicycle wheels. Rim tape (manual) sounds like motorcycle (cast) wheels. Except for the rim liner tape on bicycle wheels, but I don’t knw why that would be notably manual or machine.
[20:03:02] <andypugh> I made a wheel building stand today, hopefully the post office has the spokes. Odd wheel, 50mm through the bearing.
[20:03:06] <jdh> had 3 flats before I noticed the rim liner (bicycle) was not centered on one part. someone asked who built the (faulty) wheels.
[20:03:55] <andypugh> I had some Shimano rims that needed a strong cloth tape to bridge the nipple holes.
[20:04:45] <jdh> this tape is fine, it was just not in the right place.
[20:05:21] <andypugh> A new departure for the wheel I will build tomorrow, beaded rim.
[20:05:39] <andypugh> Bits of the tyre itself act as rim tape.
[20:05:57] <andypugh> Sorry, “beaded edge”
[20:08:23] <andypugh> http://www.northhantstyres.com/faq-tyres.html
[20:17:39] <jdh> looks like a nice design, but heavy and more expensive
[20:29:48] <andypugh> There is no strong bead loop, they do actually fall off sometimes, which is almost never a good thing. But as the Ner-a-Car has only 3hp that’s probably not too much of a worry.
[21:44:13] <witnit> I need some more high production turning jobs to quote, my machines are getting bored.
[21:44:38] <toastyde2th> wut
[21:44:44] <toastyde2th> how high is high production
[21:44:46] <toastyde2th> 10k parts a month?
[21:44:53] <witnit> 10,000 is good
[21:44:57] <witnit> 100,000 is better
[21:45:12] <toastyde2th> screw machine shop?
[21:45:15] <witnit> yup
[21:45:19] <witnit> acmes, and davenports
[21:45:27] <witnit> some single spindles hanging out too
[21:45:31] <toastyde2th> always wanted to run an acme
[21:45:40] <toastyde2th> never got the chance
[21:45:51] <witnit> well, bring a job with you and you can run mine
[21:45:59] <toastyde2th> hahaha
[21:46:01] <witnit> :)
[21:46:15] <witnit> you ever ran other multispindles?
[21:46:17] <XXCoder> bored enough to make sweet titanium pen for me? lol
[21:46:29] <witnit> 100,000 titanium pens?
[21:46:38] <XXCoder> sure if still free
[21:46:44] <witnit> ill check with nasa
[21:46:48] <XXCoder> lol
[21:47:00] <witnit> grants and all
[21:47:23] <XXCoder> I'd be surpised if it worked
[21:47:25] <witnit> I hear they have some ussr spacejunk they are planning to gravitate
[21:47:35] <witnit> Ohhh..... too soon?>
[21:49:21] <XXCoder> lol
[21:50:33] <witnit> I really like this 7i90, I think I want another one.
[21:51:03] <XXCoder> whats it
[21:52:22] <witnit> one of the mesa cards with three 50 pin connectors and it has serial and epp printer port options
[21:54:48] <toastyde2th> witnit, never
[21:55:31] <toastyde2th> ran some lathes but never more than 200 parts in a run
[21:55:58] <toastyde2th> job shop type stuff
[21:56:22] <toastyde2th> mostly chucker crap, from about 1"x3" to 20"x20"
[21:56:27] <witnit> ohh, toasty, imagine pumping out a brass compression sleeve every .8 seconds
[21:56:52] <witnit> just bangin em out =D
[21:57:00] <toastyde2th> i've seen em run, just wished i could learn setup
[21:57:17] <witnit> its not too bad, in fact the more spindles and tooling, the easier
[21:58:17] <toastyde2th> my co-worker used to run a multispindle, he made artillery fuzes
[21:58:25] <toastyde2th> 4"x8"
[21:59:03] <witnit> you may have to set three different chamfer tools up but you only ever are working on one spindle at a time so its like, setting up three small lathes instead of 3 things on one lathe
[21:59:08] <witnit> :)
[21:59:16] <toastyde2th> i got out of machining and went back into IT after like 3/4 years
[21:59:17] <toastyde2th> so
[21:59:47] <witnit> yeah, I dont like getting too dirty anymore
[22:00:18] <witnit> I prefer to get a little dirty on a setup and let the other guys keep them loaded
[22:00:27] <toastyde2th> yeah
[22:00:30] <toastyde2th> that was the one thing i didn't like
[22:01:10] <toastyde2th> the stuff we did was mostly our own product, so there wasn't enough programming and drawing work for me to do those things dedicated
[22:01:35] <toastyde2th> kinda dumb, actually - we had just as many machinists as machines, no operators
[22:01:40] <toastyde2th> kinda dumb way to run a shop but whatever
[22:08:27] <witnit> http://199.168.73.34/davenport.3gp
[22:08:53] <witnit> noisy during machine time
[22:10:10] <witnit> I ran miles of steel through that machine
[22:10:15] <witnit> MILES
[22:11:14] <witnit> quickly too, something like 8" every 5 seconds
[22:11:34] <toastyde2th> hahaha
[22:12:03] <witnit> Its hard to pay for a good machinist
[22:12:12] <witnit> they are quite valued
[22:13:35] <witnit> and one thing I learned is a good machinist can make good parts on bad machines and bad machinists will make bad parts on good machines.
[22:17:12] <cradek> that's two things
[22:17:40] <cradek> (#3: really bad machinists can make bad machines out of good machines)
[22:21:20] <PetefromTn_> Well pretty happy guy here fellas...
[22:21:51] <PetefromTn_> I just got back from Knoxvegas.
[22:22:03] <XXCoder> as a winner? lok
[22:22:12] <PetefromTn_> Went to look at some tools a retiring machinist was selling.
[22:22:23] <PetefromTn_> He had some GOODIES in there...
[22:22:29] <PetefromTn_> ;)
[22:22:48] <XXCoder> ah you cured your light wallet syndome eh
[22:22:54] <XXCoder> er HEAVY wallet
[22:23:12] <PetefromTn_> He had a BUNCH of stuff I would like to have gotten but I did not have enough cash.
[22:23:30] <PetefromTn_> But what I did get I think I got GREAT deals on.
[22:24:13] <PetefromTn_> I got a BRAND NEW in the box Mitutoyo 8" coolant proof digital caliper complete with battery, certs everything never been used.
[22:24:38] <PetefromTn_> I got a nice condition Brown and Sharp best test DTI .0005
[22:24:55] <PetefromTn_> I got a decent 0-3
[22:25:02] <PetefromTn_> depth micrometer I have been needing.
[22:25:31] <PetefromTn_> I also got a bunch of cool DTI indicator holders for mounting in and on the spindle
[22:25:57] <PetefromTn_> I got a couple nice condition vise stops that clamp on the jaws,
[22:26:23] <PetefromTn_> I got a brand new pistol grip air nozzle like comes on the Haas machines for my Cincinatti.
[22:26:44] <PetefromTn_> I got a brand new bottle of Diekem and tap magic
[22:27:00] <witnit> tap magic
[22:27:11] <PetefromTn_> some nice old lathe inside calipers
[22:27:11] <witnit> that stuff is like gold
[22:27:19] <PetefromTn_> yup its good stuff.
[22:27:26] <XXCoder> nice
[22:27:37] <witnit> so you took pictures right? :)
[22:27:39] <XXCoder> not sure what half those stuff is but sounds nice lol
[22:27:45] <PetefromTn_> a couple other things I cannot think of right now.
[22:28:10] <PetefromTn_> Got it all for $200.00
[22:28:29] <XXCoder> oh today was my first day at machinist shop job
[22:28:38] <XXCoder> wow, I saw the largest surface ever
[22:28:41] <PetefromTn_> sweet man how did it go?
[22:28:48] <XXCoder> It must have been 6' by 10'
[22:28:57] <XXCoder> I can't imange how much it was
[22:28:59] <PetefromTn_> no pictures yet just got back home
[22:29:35] <toastyde2th> how thick was it
[22:29:41] <PetefromTn_> I am pretty sure that 8" brand new Mitutoyo coolant proof caliper costs more than what I paid for everything.
[22:29:44] <XXCoder> but yeah mostly boring stuff like videos orention and such. i'll start on assembling wire holders so not too fancy. I do want to evenually train on cnc machines there.
[22:29:54] <XXCoder> toastyde2th: looked like 8 inches, but I was pretty far off it
[22:30:11] <toastyde2th> 10-15k
[22:30:35] <XXCoder> hm was thinking around car-ish (more fancy) prices lol like 30k
[22:30:50] <toastyde2th> nah, big granite doesn't cost a ton if it's thin
[22:30:59] <toastyde2th> usually big plates like that will be feet thick
[22:31:10] <XXCoder> it could be, I was more than 15 feet away
[22:31:13] <toastyde2th> we had a plate that was 5x12 or so, but it was 4' tall
[22:31:21] <XXCoder> so my eyeball has around 20% error rate
[22:31:38] <XXCoder> whoa thats hella thick
[22:31:51] <toastyde2th> ya, big plates need to be thick so you can put heavy parts on em
[22:32:08] <toastyde2th> something that size that's only a foot thick will bend a lot
[22:32:19] <toastyde2th> most shops are fine with this because they're not dropping parts that weigh a ton
[22:32:27] <toastyde2th> it's usually just awkwardly sized stuff
[22:32:43] <XXCoder> it looked like it had massive amount of support
[22:32:57] <XXCoder> like it'd hold up couple tons
[22:32:59] <toastyde2th> it does, but that doesn't help the accuracy because of the type of support it has
[22:33:01] <PetefromTn_> http://www.penntoolco.com/catalog/products/products.cfm?categoryID=6988 that is the caliper I got...
[22:33:02] <XXCoder> but then what do I know
[22:33:05] <toastyde2th> the issue is not "is it supported"
[22:33:12] <toastyde2th> the issue is "does the reference surface move when you add load"
[22:33:14] <PetefromTn_> the 8" hardened jaws model brand new in box.
[22:33:27] <XXCoder> nice pete :)
[22:33:47] <XXCoder> considering that alone covers half of $200 you used
[22:34:03] <toastyde2th> if you pay for a plate to be AA grade or whatevs, it's a waste of money if the plate goes out of spec because the part weight makes the table concave
[22:34:14] <PetefromTn_> yeah I am pretty pleased....
[22:34:16] <XXCoder> makes sense
[22:34:53] <XXCoder> I'm glad I dont need all that much precision. I hope my cnc reaches around 0.1 mm precision which is enough to learn
[22:35:05] <toastyde2th> you can buy AA grade plates that are tiny
[22:35:15] <toastyde2th> and they do just fine because you aren't able to fit a half-ton part on them
[22:35:25] <XXCoder> since I plan to make boxed gantry it probably would easily surpass that
[22:35:32] <toastyde2th> a 12x24 plate or thereabouts is like 200-300 brand new
[22:35:39] <XXCoder> interesting
[22:36:04] <PetefromTn_> http://www.ebay.com/itm/NEW-BROWN-SHARPE-BesTest-Dial-Test-Indicator-0005-0-15-0-599-7030-3-/191128084799 Thats the same indicator I got...
[22:36:47] <XXCoder> heh if I ever have plety money i wanna try make expoxy grinate
[22:36:52] <XXCoder> cant spell that word :P
[22:36:54] <toastyde2th> plate accuracy only gets expensive on larger plates because the laps they use to surface the plates start to get wavy at like 3"
[22:37:08] <toastyde2th> or rather will put a waviness in the plate at about 3'
[22:37:26] <toastyde2th> flattening a 24" plate is like hitting the side of a barn
[22:37:40] <toastyde2th> hard to miss
[22:39:04] <XXCoder> cool
[22:39:10] <PetefromTn_> http://www.mscdirect.com/product/01297076 Got one of these in there too...
[22:43:25] <PetefromTn_> also got some of the indicol spindle mount holders too. I am like a kid at christmas here LOL..
[22:50:06] <PetefromTn_> Going to look at a Fowler set of depth mics tomorrow. They look brand new too. trying to get some decent quality tools here for my work. Tired of the chinese crap I have been using.
[22:50:57] <XXCoder> :
[22:50:59] <XXCoder> :)
[22:52:51] <witnit> good for you pete, money well spent
[22:53:36] <PetefromTn_> Thanks man I have not had tools like this and it sure was nice to get a good deal.
[22:53:54] <PetefromTn_> looking at new prices on some of it I got a REAL good deal I think.
[22:54:13] <PetefromTn_> Still hurt to blow the money but as they say cry once and enjoy a quality tool for years.
[22:54:38] <toastyde2th> recommendation, get everything combination vernier and digital
[22:54:49] <toastyde2th> all my mics no matter what type have both
[22:54:58] <toastyde2th> (depth, internal, external)
[22:55:53] <toastyde2th> but unless you buy mitutoyo or similar, the batteries will die constantly
[22:56:35] <witnit> I have some carbide faced mitu digial calipers
[22:56:45] <witnit> digital*
[22:56:55] <witnit> but the digital part is broken..
[22:57:00] <toastyde2th> ya, mitutoyo calipers are really the only way to go
[22:57:13] <witnit> so, just carbide faced yardstick ;)
[22:57:19] <toastyde2th> lol
[22:57:21] <PetefromTn_> yeah that is what I got carbide faced coolant proof 8:
[22:58:07] <PetefromTn_> They seem really nice and smooth. Will be nice to NOT have to worry about getting coolant dripped on them
[22:58:28] <witnit> oh nope, these are starret carbide faced
