[01:33:02] <MacGalempsy> slow night in here tonight
[02:47:50] <_DJ_> moin
[03:55:25] <MacGalempsy_> morning _DJ_
[03:55:43] <_DJ_> good morning macGalempsy
[08:11:33] <Jymmm> Are industrial rubys cheap?
[08:16:36] <Tom_itx> cheaper than industrial diamonds
[08:17:35] <Tom_itx> FOB Price: US $49-105 / Kilogram
[08:17:47] <Tom_itx> min 1kg
[08:19:37] <Tom_itx> you making watches?
[08:20:01] <Tom_itx> lasers?
[08:20:38] <Jymmm> No, my trackball uses them but they've changed their mold-injection somehow so the holder deforms and makes it useless/course
[08:20:51] <Jymmm> coarse
[08:21:22] <Jymmm> I do have one where the ruby looks "chipped"
[08:22:13] <Jymmm> I was tinking of replacing them with chrome bearings instead
[08:22:28] <Tom_itx> i've never looked inside mine
[08:23:21] <Jymmm> I also want to replace their crap plastic balls in the scrollring with trustbearing if i can find the right size
[08:23:43] <Jymmm> apx 3" OD, 2.75" ID
[08:24:23] <Tom_itx> machine a new trackball from billet Ti
[08:24:59] <Tom_itx> that way it won't warp
[08:25:08] <Jymmm> Sure, let me get the Ti billet from ya
[08:25:21] <Tom_itx> i'll get some today at the scrap for ya
[08:25:22] <Tom_itx> :D
[08:25:38] <Jymmm> you do that =)
[08:25:47] <Tom_itx> they actually have 3' rectangular al there
[08:26:13] <Jymmm> oj, and Pt too while you're at it
[08:26:17] <Jymmm> oh*
[08:26:26] <Tom_itx> i don't think they have much Ti actually
[08:26:37] <Jymmm> s/much/any/
[08:26:53] <Tom_itx> maybe some sheet and small roundbar
[08:27:13] <Jymmm> Why would you use ruby over chrome balls?
[08:27:29] <Tom_itx> what's the hardness of both?
[08:27:37] <Jymmm> 9 ruby
[08:28:07] <Jymmm> Ruby has a Mohs hardness of 9.
[08:28:13] <Jymmm> Diamond - 10
[08:29:01] <Tom_itx> they must have taken a hint from watchmakers
[08:29:04] <Jymmm> http://periodictable.com/Properties/A/MohsHardness.al.html
[08:29:50] <Jymmm> Molybdenum 5.5MPa
[08:30:12] <Jymmm> Titanium 6.MPa
[08:30:27] <Jymmm> Platinum 3.5MPa
[08:31:37] <Jymmm> Maybe they did, but with a cueball sized ball, the ruby chips, and the ABS holder deforms over time
[08:36:23] <Tom_itx> get one from an old arcade
[08:37:03] <Tom_itx> http://www.itacsystems.com/38-50mm.html
[08:37:09] <Tom_itx> build that into your desk
[08:38:12] <Jymmm> heh
[08:39:57] <Tom_itx> i used to use a thumb ball but not so much anymore
[08:40:09] <Jymmm> If I'm ging to go all out like that, I might as well build a reverse galvinometer that reacts to my hand movement
[08:40:29] <Tom_itx> i was looking for such a trackball
[08:40:38] <Tom_itx> i know a dude that had one he used in Acad
[08:40:41] <Jymmm> a ballless one?
[08:40:55] <Tom_itx> it had a ball but you 'felt' it instead of moved it
[08:41:02] <Jymmm> ah
[08:42:19] <Tom_itx> i can't remember the Mfg
[08:44:06] <Jymmm> I'd still need a scrollring somehow
[08:45:08] <Valen> spaceball
[08:46:18] <Jymmm> That's just a cdconnex with a ball attached
[08:46:28] <Jymmm> not really a mouse/trackball
[08:47:03] <Jymmm> Valen: do you have one?
[08:47:12] <Valen> nope
[08:49:13] <Jymmm> I *wish* they made it as a 3D/mouse
[08:51:10] <Tom_itx> http://www.3dconnexion.com/buy/shop.html?list_product_type=device
[08:51:11] <Tom_itx> bingo
[08:51:38] <Jymmm> Tom_itx: we were just talking about those =)
[08:51:51] <Jymmm> Tom_itx: they're not mice replacements
[08:51:51] <Tom_itx> i know
[08:52:05] <Tom_itx> well they should be
[08:52:15] <Jymmm> they should, but aren't
[08:52:46] <Jymmm> http://www.amazon.com/3DConnexion-SpaceBall-12-Button-Trackball-Mouse/dp/B003NYIGUQ
[08:53:21] <Tom_itx> that's somewhat similar to what he had
[08:53:53] <Tom_itx> they had very few drivers at the time
[08:53:53] <Jymmm> ah
[08:53:56] <Tom_itx> acad was one
[08:54:03] <Jymmm> still very few =)
[08:54:16] <Jymmm> well, limited actually
[08:55:46] <Tom_itx> that was back when you had a separate ram board in your pc to do cad :)
[08:56:06] <jdh> and if you were lucky, a FPU
[08:56:24] <Jymmm> and > 640KB
[09:49:49] <JT_Shop> a new low for me 15.285714286 stone
[09:55:25] <archivist_herron> 9 decimal places! one fart and that will be incorrect
[09:55:49] <PetefromTn> Hell I got ya beat LOL...
[09:56:29] <JT_Shop> it's already incorrect
[09:56:52] <PetefromTn> 15.7142857 stone
[09:57:05] <JT_Shop> ya beat me the wrong way
[09:57:16] <PetefromTn> But I just finished eating a glazed donut so who knows man....LOL
[09:57:39] <JT_Shop> lol my target is 13 stone
[09:57:40] <PetefromTn> Its all good unless you are a short bastard...
[09:58:24] <JT_Shop> I'm not short, just height challenged
[09:58:37] <PetefromTn> damn I have not seen 180 in years...
[09:58:50] <PetefromTn> USed to be a skinny bastard now I am "FULL"
[09:59:09] <JT_Shop> me neither, but 1hr of mountain biking a day makes it come closer every week
[09:59:25] <JT_Shop> my shape used to be round
[09:59:29] <PetefromTn> Are you on any particular die?
[09:59:32] <JT_Shop> got tired of that shape
[09:59:34] <PetefromTn> diet?
[09:59:56] <JT_Shop> no, I just manage my calorie intake to be less than I burn each day
[10:00:00] <PetefromTn> I ride my custom built home-made recumbent bike on the local trail and greenways.
[10:00:15] <JT_Shop> got a photo of it?
[10:00:33] <PetefromTn> never went actuallly mountain biking but have owned several including a Cannondale awhile back.
[10:00:40] <PetefromTn> Yeah somewhere.. Lemme see.
[10:03:39] <PetefromTn> http://imagebin.org/276207 This was before I added some better components, a bike computer, and an actual recumbent fork. It was wearing a mongoose BMX bike fork here....
[10:04:29] <PetefromTn> http://imagebin.org/276208
[10:05:48] <PetefromTn> Still need to get a set of matching brake handles LOL and I want to make a nice mount for my Smartphone so I can use the GPS while I ride.
[10:08:15] <jdh> I got a bag that mounts on the bar&stem that holds my phone
[10:08:29] <jdh> touchscreen works fine through the clear top
[10:10:21] <jdh> guess that won't work on an old-folks recumbent though
[10:12:35] <JT_Shop> PetefromTn, did you build it from parts?
[10:15:01] <JT_Shop> is there a link between the handlebars and the fork on the far side?
[10:17:55] <CaptHindsight> PetefromTn: http://imagebin.org/276211 custom built home-made recumbent bike?
[10:18:13] <PetefromTn> No I built it from scratch except for the rear triangle which came from a ten speed.
[10:18:30] <CaptHindsight> oh the red one!
[10:18:43] <PetefromTn> There is only the link on the left side with a ball mount.
[10:19:01] <PetefromTn> CaptHindsight: LOL exactly...
[10:19:12] <PetefromTn> My kids neglected toys LOL
[10:19:48] <Jymmm> PetefromTn: Uh, is that a passanger front seat? (6" red pipe)?
[10:20:01] <jdh> that would be a passenger 'mount'
[10:20:08] <Jymmm> lol
[10:20:24] <PetefromTn> Gotta go meet my six year old for lunch at school BRB..
[10:20:41] <Jymmm> jdh: and the sproket is.....
[10:22:50] <jdh> painful.
[10:23:23] <Jymmm> heh
[10:23:50] <jdh> I got new pedals for mine the other day, but it gets dark shortly after I get home.
[10:24:53] <JT_Shop> get headlights
[10:25:20] <jdh> I only have streets to ride on. I'm more worried about being hit.
[10:28:14] <JT_Shop> that sucks
[10:28:44] <jdh> yeah. I think they should make the time so it is always sunset at 9pm
[10:28:53] <JT_Shop> they are building 26 miles of mountain bike trails about 5 miles from my house, they have about 14 miles done
[10:29:02] <jdh> cool
[10:29:32] <JT_Shop> I rode the hwy (4 lane 65 mph) a few times but didn't like the noise
[10:30:07] <jdh> I try to stick to residential areas. Not much in the way of shoulders or friendly drivers here.
[10:30:47] <Jymmm> jdh: do you stop at stop signs?
[10:30:56] <jdh> they are working on a cross-city bike path, but it is currently unconnected and crosses some major roads.
[10:31:24] <jdh> Jymm: if I am on real roads I do. Not usually for inter-neighborhood ones though.
[10:33:02] <CaptHindsight> are they paved bike trails?
[10:33:39] <jdh> ours are (will be)
[10:34:26] <CaptHindsight> most here are paved withing 50 miles of the city, they connect with national trails that I hear are mostly gravel
[10:34:53] <JT_Shop> these trails are natural
[10:35:30] <jdh> mine isn't much of a city. 50 miles from here is either ocean, swamp, or middle of no where.
[10:36:14] <CaptHindsight> JT_Shop: is you area hills and valleys?
[10:42:02] <CaptHindsight> http://www.3ders.org/articles/20131107-world-first-3d-printed-metal-gun.html
[10:43:22] <CaptHindsight> yikes, use a better test stand
[10:45:08] <JT_Shop> CaptHindsight, yes
[10:47:23] <JT_Shop> CaptHindsight, http://www.mapmyride.com/workout/418597981
[10:47:51] <JT_Shop> you can see the route and elevation change
[10:48:01] <jdh> you have to be a 'friend' to see someone elses workout
[10:48:13] <JT_Shop> hmm that sucks
[10:48:49] <jdh> there is an option in the app to make it visible to you, friends, all (android version anyway)
[10:49:30] <JT_Shop> let me see if I can find it
[10:49:58] <JT_Shop> is there a place to get games for your andriod like solitare? I'm a new not know how android user
[10:50:27] <JT_Shop> see if you can view it now
[10:51:09] <jdh> there are billions of solitaires... play.google.com
[10:51:49] <JT_Shop> ok thanks, the eye phone has the app center thing so I was looking for something like that
[10:51:54] <JT_Shop> new not know how yet
[10:52:20] <jdh> it is listed as "Play Store" on the phone
[10:52:47] <jdh> but, if you are at a computer, you can do it via the web interface and also download to your device from there.
[10:59:16] <PetefromTn> Okay back again. We actually have some nice local trails and of course you can bike in the Great Smoky Mountains National Park around cades Cove Loop road too.
[11:31:06] <jdh> in Murville?
[11:34:01] <PetefromTn> yp...
[11:34:46] <PetefromTn> talkin road trail here but there are also lots of offroad trails around here too.
[11:39:32] <jdh> no hills at all here. One of the weirdest parts of moving here from knoxville
[11:39:43] <archivist> I prefer to get paid to exercise, voluntary exercise seems like effort :)
[11:40:12] <jdh> I prefer getting paid to think.
[11:40:53] <skunkworks> I perfer to get paid for whatever I want to do..
[11:41:12] <archivist> I can feel my muscles tonight after shifting a ton or more
[11:42:24] <jdh> Ideally, I would get paid for doing nothing but I haven't had much luck with that.
[11:42:46] <jdh> well... some days I guess I do.
[11:44:37] <archivist> and after some rough calculations over 2 tons
[11:51:35] <PetefromTn> You guys wanna hear a crazy freakin' Idea I had..
[11:57:04] <archivist> is the crazy infectious
[12:13:43] <IchGuckLive> hi all B)
[12:24:09] <PetefromTn> Actually on second though I just told it to my wife and she laughed at me so forget it LOL...
[12:31:00] <jthornton> in that case we really want to hear it
[12:31:36] <PetefromTn> ;)
[13:05:00] <IchGuckLive> im cutting the harvest videos
[13:20:51] <IchGuckLive> its heavy rain outside
[13:24:23] <IchGuckLive> not as heavy as in the philipines but its quite a bit for germany
[13:24:41] <IchGuckLive> http://www.nrlmry.navy.mil/TC.html
[13:25:02] <IchGuckLive> Haiyuan is a supercyclon
[13:33:41] <IchGuckLive> im off BYE
[14:56:45] <tjb1> KimK, sorry had to hit the bed last night
[14:57:00] <tjb1> It came out to $16 after coupon and rebate, still a good deal and Newegg is a good place for rebates
[15:23:14] <KimK> tjb1: Hi, hey great, glad you got a good deal. I don't know why they marked up the price for me, I guess I'm not on their "preferred customer" list... ("Who? Never heard of him. Tell him it's double!")
[15:27:03] <tjb1> Did you put in the coupon code?
[15:27:14] <tjb1> It would of dropped it to $26
[15:31:23] <KimK> No, I didn't bother, I don't like to help or encourage rebates. Like I said, if they want to lower the price, fine. Or else don't. None of this in-between stuff, I have enough extra work to do already. Hey, I don't mean to seem grouchy, how are you doing?
[15:33:18] <tjb1> Good, done with work. Get to relax all weekend and probably do BF4
[15:34:18] <KimK> BF4?
[15:36:12] <tjb1> Battlefield 4
[15:37:39] <KimK> Ah, it must be either a new movie or a new video game?
[15:37:47] <KimK> Maybe both?
[15:39:14] <WalterN> its a popular computer game
[15:39:26] <tjb1> I play it on xbox :)
[15:40:05] * KimK probably got an email offering to send an explanation, but they wanted me to send in a rebate form...
[15:40:19] <WalterN> what are you talking about?
[15:41:32] <KimK> Who, me? I'm just blathering, never mind.
[15:42:24] <tjb1> Maybe finish 3D printing my prototype CAT40 gripper :D
[15:44:10] <tjb1> Here's a preview - https://www.dropbox.com/s/h7w7ebbm772a1ij/2013-11-08%2016.27.32.jpg
[15:45:01] <PetefromTn> Hey thats pretty sweet man.
[15:46:30] <KimK> tjb1: Yes, looks good. And speaking of that bottle of water by your keyboard, don't I still owe you your CD case(s) and whatever was with them (bottle of water, something else)?
[15:47:02] <tjb1> Thanks! Shop is a little busy to push through the parts right now so I am printing them at home to make 100% sure that everything works
[15:47:06] <tjb1> What's that KimK?
[15:47:37] <KimK> Did you leave a CD case(s) here? Or was that someone else?
[15:47:48] <tjb1> I think you have me confused with someone else :)
[15:48:01] <KimK> OK, someone else then. Nevermind.
[15:48:13] <tjb1> I live in NY
[15:52:02] <KimK> Back in a bit, need to restart
[15:54:36] <tjb1> PetefromTn: I printed the threads on the white pieces, 2-5/8 - 16
[15:54:45] <tjb1> Had to file the externals a bit to get it to work
[15:54:58] <PetefromTn> Hey man thats cheating LOL
[15:55:52] <PetefromTn> Oh if only we could really print them from a hardened tool steel or something. I know they are working with epoxy based metal but that is not the same thing I think.
[15:57:54] <tjb1> PetefromTn: http://www.youtube.com/watch?v=CsEqKbNalh4
[15:59:51] <PetefromTn> Yeah I have seen similar. Interesting but not sure it replaces the old fashioned subtractive processes LOL
[16:03:12] <tjb1> We can only dream!
[16:03:29] <WalterN> can I open a bobcad cam file with a normal text editor?
[16:05:36] <WalterN> herm, weird
[16:09:00] <tjb1> The g-code file?
[16:09:43] <WalterN> yeah
[16:10:01] <WalterN> it was all screwy, so I saved it as .txt
[16:10:36] <WalterN> instead of the default .cnc
[16:11:25] <tjb1> Screwy even in notepad?
[16:11:34] <WalterN> I opened it in Gedit
[16:12:00] <WalterN> it has a lot of extra 'jumble'
[16:13:29] <_DJ_> gn8
[16:15:52] <PetefromTn> sure I open TXT files all the time that way.
[16:16:39] <WalterN> PetefromTn: yeah, but it seems from bobcad, the CAM files that it saves as (.cnc) is not pure text
[16:17:08] <tjb1> Anyone have any experience with these? http://www.youtube.com/watch?v=RtLCbvUvhRs
[16:19:56] <tjb1> I may try to print one
[16:20:51] <andypugh> Am I being over-sensitive or is the commenter (Sirius) being a bit of an ass-hat here, talking about my video? (Yoi may have to expand his comment) http://www.youtube.com/watch?v=uycWEX3_eHA&feature=share&list=UUexvgsGz_QFvOublovDYoTQ
[16:22:37] <PetefromTn> WalterN: DUnno man don't have Bobcadcam sorry.
[16:22:42] <tjb1> " I know a lot about machining tools, but no hand on experience"
[16:22:54] <tjb1> Instant disqualification as an idiot :)
[16:23:06] <tjb1> Or qualification as an idiot?
[16:23:16] <tjb1> Dunno, he is an idiot lol
[16:23:45] <WalterN> tjb1: somebody said that on a job application?
[16:24:12] <andypugh> It's quite funny his suggestion that I should watch Keith Fenner videos, he is one of my subscribers :-)
[16:24:37] <tjb1> Where is U axis?
[16:24:41] <tjb1> WalterN: from comment on video
[16:26:23] <andypugh> Typo, I meant Y axis.
[16:26:47] <PetefromTn> Climb cutting with a huge cutter if there was excess slop you would know it pretty quick no?
[16:27:03] <tjb1> andypugh: Nice touchscreen setup
[16:28:13] <andypugh> The Gibbs probably do need work, in truth.
[16:28:13] <WalterN> oh heh
[16:29:19] <Connor> Okay, so, Thread going on the mailing list about a usb cam for edge finder.. But, I've yet to see one listed... Anyone know of a good one to use ? and how are they mounting it? Direct inline with spindle, or offset on it's own mount ?
[16:29:40] <andypugh> I think Ruffle gave the name of the one he used.
[16:30:25] <WalterN> anyone know of any good places to host email and website, where I dont have to set up all the crazyness for the email?
[16:30:44] <cradek> I've heard good things about fastmail.fm for email
[16:31:01] <cradek> no idea where to host a website
[16:31:13] <andypugh> I have been with newbieite for several years, and it's fine.
[16:31:24] <andypugh> (newbiesite)
[16:31:50] <tjb1> www.000webhost.com is free
[16:31:51] <andypugh> You get lots of email addresses and a website (with the toys, like PHP and SQLite)
[16:32:10] <tjb1> http://www.namecheap.com/ for domain
[16:32:11] <WalterN> screw PHP
[16:32:51] <WalterN> I dont mind setting up email and spam prevention and stuff, its just kinda a pain in the butt
[16:33:26] <WalterN> esp. SSL for something like IMAPS
[16:34:55] <Connor> http://bbs.homeshopmachinist.net/threads/27425-A-mill-camera?highlight=lifecam
[16:35:05] <Connor> doesn't tell which camera.. and, it's a bit old.. 2008.
[16:35:16] <andypugh> I am happy enough with http://www.newbiesite.com I had another site with http://www.zyma.com and they were cheaper and also pretty good.
[16:36:12] <Jymmm> WalterN: US?
[16:36:21] <WalterN> Jymmm: correct
[16:36:26] <Jymmm> WalterN: https://www.bluehost.com/
[16:37:26] <WalterN> oh hey, ruby on rails
[16:38:17] <Jymmm> WalterN: unlimited everything, but you can't abuse the CPU's, so write clean code =)
[16:38:25] <Jymmm> WalterN: And you can get shell access too
[16:38:59] <jdh> there is another webcam mill article in a more recent digital machinist
[16:39:37] <WalterN> yeah, SSH access is kind of important to me :3
[16:42:48] <cradek> on the first shared-hosting system I used, the disk quota was 1MB
[16:44:00] <Jymmm> cradek: CAN YOU FEEL THE POWER !!!
[16:44:17] <cradek> > By the end of 1992 the Cleveland Free-Net had grown to over 36,000 active accounts handling over 11,000 logins a day.
[16:47:50] <andypugh> Had the Web even been invented then?
[16:48:14] <andypugh> I recall when it was pretty much unthinkable to transfer a 1MB file electronically.
[16:48:24] <WalterN> heh
[16:49:01] <cradek> andypugh: not that I had any access to. usenet and email were the thing.
[16:49:05] <andypugh> And I was late on the scene, the slowest modem I ever owned was 28k8
[16:49:42] <cradek> I spent many many hours behind a 300 baud acoustic
[16:50:19] <andypugh> cradek: Yeah, I thought so. I think it was 1992 when we got an email at work saying "there is this cool new thing called the world wide wedb, you might want to have a look, here are the addresses of the 5 current sites" :-)
[16:51:33] <cradek> in those early days, you could go to the bookstore and buy a book of URLs. there was no meaningful web search (although you could sort of search for files available by ftp)
[16:51:48] <cradek> I wish I had one of those books still, for the laughs
[16:51:51] <andypugh> Thinking about it, I don't know what the modem was in my Hall of Residence at college. That was acoustic, and you dialed out by dropping a plastic punched-card through a reader.
[16:52:07] <cradek> huh! I have never seen that.
[16:52:15] <cradek> I dialed with the rotary dial of course
[16:52:26] <andypugh> We heard about Chernobyl through that modem.
[16:52:38] <cradek> a touch tone line cost extra...
[16:52:47] <WalterN> I didnt come in to the internet world until the 56k modem days
[16:53:56] <WalterN> which is kinda funny, where I grew up, they still dont have any internet access available other than satellite
[16:56:13] <andypugh> I recall Gopher being a lot more useful for finding stuff than www
[16:56:15] <Loetmichel> WalterN: hrhr
[16:56:27] <Loetmichel> my first modem was a Discovery 1200+
[16:56:33] <Loetmichel> ... loooong ago ;-)
[16:57:03] <Loetmichel> cradek: a friend had a 300 baud acoustic
[16:57:23] <Loetmichel> .., even with a "post" eagle on it ;-)
[17:00:39] <Jymmm> Loetmichel: cradek had (has?) a 300 baud acoustic
[17:08:46] <tjb1> Inventor crashing never gets old...
[17:16:49] <WalterN> anyone know where I could get a fanuc O/OO/O-Mate PDF?
[17:17:13] <WalterN> PDF of the operator's manual
[17:24:24] <WalterN> I'm getting ready to make a generic program for a part that has a rather large range of sizes
[17:24:38] <WalterN> with variables and stuff
[17:25:30] <WalterN> I've done fun stuff with C and Java, but never tried it in G and M code... heh
[17:27:03] <andypugh> http://www.practicalmachinist.com/vb/machinery-manuals-brochures/fanuc-o-oo-o-mate-o-mc-oo-mc-maintenance-operator-s-manuals-247009/
[17:28:34] <WalterN> so I need to email thhat guy?
[17:30:48] <andypugh> Just the first thing that Google found.
[17:42:13] <Loetmichel> Jymmm: i have read it.
[17:43:21] <Loetmichel> btw: the modulation on 300 b/s was SO easy, i think i could build a working 300baud acoustic out of spare parts laying around here and a bit of software.
[17:43:46] <Loetmichel> even a 1200 baud, if i find some good speakers and mics ;-)
[17:45:07] <andypugh> This is quite a pile of cast iron chips: https://picasaweb.google.com/lh/photo/_G0r_v_xAMLbDRznCRhP-tMTjNZETYmyPJy0liipFm0?feat=directlink
[17:50:54] <Tom_itx> your pile?
[17:52:53] <andypugh> Yes
[17:53:44] <Tom_itx> what is it?
[17:53:49] <Tom_itx> gonna be...
[17:53:51] <andypugh> Making one of these from a solid lump" http://i227.photobucket.com/albums/dd52/drzipper/Rivett%20Accessories/RivettEccentricToolHolder002.jpg
[17:54:33] <Tom_itx> gave up on the brazing job?
[17:55:15] <andypugh> The brazed repair is functional, but hardly pretty. And it does actually get in the way.
[17:55:46] <Tom_itx> i bet it was more an irritation factor :)
[17:55:49] <andypugh> It makes getting the tool up to the chuck difficult.
[17:56:49] <Tom_itx> what did you use to program it?
[17:57:10] <andypugh> MeshCAM this time.
[17:57:31] <Tom_itx> i bet that's gonna take a while to cut
[17:57:51] <andypugh> It takes one evening per side.
[17:58:59] <andypugh> I am surprised that nobody has diagnosed my Y-axis as having a backlash problem yet, it's pretty evident from the machining pattern.
[17:59:45] <Tom_itx> i noticed
[18:00:29] <Tom_itx> are you cutting both directions on the body?
[18:01:06] <andypugh> I have a bigger, preloaded ballscrew. Special order from the manufacturer. When it arrived it has external ball transfer tubes not shown in the drawing. Which I suspect means it won't fit.
[18:01:32] <andypugh> Yeah, the CAM does a zigzag
[18:01:43] <andypugh> It also does a lot of air-cuts.
[18:02:41] <Tom_itx> using roughing cutters for the moment?
[18:02:45] <andypugh> Bit so far, they all do. I have not seen one yet that doesn't rapid to safe-height then feed to current height (when it should know that it can rapid to the previous cut level)
[18:03:56] <Tom_itx> you mean rapid to the next level as it cuts?
[18:04:02] <andypugh> That was done with a ball-end cutter.
[18:04:09] <Tom_itx> knowing the material is now gone..
[18:04:16] <andypugh> Yes.
[18:04:31] <Tom_itx> i would probably have to manually do that on mine
[18:04:51] <Tom_itx> i could connect the layers so it would be one continuous pass
[18:04:59] <Tom_itx> which i do quite a bit
[18:05:11] <Tom_itx> it doesn't go to z clear that way
[18:05:35] <andypugh> Like this: http://www.youtube.com/watch?v=GU3jcyPze0U The previous cut started from the same point, it really doesn't have to go back to the start at the feed rate
[18:05:35] <Tecan> (GU3jcyPze0U) "Silly Air Cuts" by "andy pugh" is "Tech" - Length: 0:02:57
[18:05:38] <Tom_itx> but i would probably cut all one direction so in which case it would
[18:06:04] <Tom_itx> i know what you mean
[18:07:59] <Tom_itx> i don't know if newer cad cam do that or not but mine doesn't. i'd have to manually edit the layers then post it
[18:08:15] <Tom_itx> might be worth it on that
[18:08:45] <Tom_itx> it doesn't automatically do it
[18:11:04] <Tom_itx> i may have used a roughing cutter before the ball mill until i got a bit closer to the finished cut
[18:11:14] <Tom_itx> i'm not sure how much you had to remove there though
[18:11:34] <andypugh> I roughed with a 20mm then semi-finished with a ball-nose.
[18:12:09] <andypugh> It started as a 4" x 2" cylinder of continuously-cast iron
[18:12:20] <Tom_itx> we had some large open areas it proved quicker to drill down to near depth then clean it out instead of using a mill cutter
[18:12:45] <Tom_itx> with less warpage on aluminum
[18:13:16] <andypugh> If I was doing more than one I would make the same part at 102% out of model board and send it to the foundry.
[18:14:32] <andypugh> Working in cast-iron with HSS tooling you can only really work at 800rpm, and then that means feeds about 80m/min and long cycle times.
[18:14:56] <Tom_itx> much like Ti
[18:15:02] <andypugh> I could probably have knocked that out of Aluminium in an hour.
[18:15:25] <andypugh> Or 20 mins from HPPU.
[18:15:34] <andypugh> (HDPU I mean)
[18:23:09] <Tom_itx> what would you consider a good press fit for a bearing?
[18:23:43] <Tom_itx> .001" ?
[18:24:15] <andypugh> The bearing catalogues go into great detail. It depend on the mounting.
[18:24:17] <Tom_itx> smallish bearing R6 R8
[18:24:30] <Tom_itx> standard dimensions
[18:24:53] <Tom_itx> 1.125 for the 8 and .875 for the R6
[18:25:19] <andypugh> I think it varies for static inner or static outer, and if it is interference both sides.
[18:26:15] <Tom_itx> http://tom-itx.dyndns.org:81/~webpage/kat/Bellhousing7.jpg
[18:26:18] <Tom_itx> is one
[18:26:27] <Tom_itx> http://tom-itx.dyndns.org:81/~webpage/kat/Bellhousing6.jpg
[18:27:55] <andypugh> I have typically either guessed for my own stuff, or worked through the bearing catalogue recomendations for work stuff.
[18:30:51] <Tom_itx> i guessed
[18:31:03] <Tom_itx> and hoped for the best on that old lathe
[18:31:44] <Tom_itx> http://tom-itx.dyndns.org:81/~webpage/kat/bell_brushend2.jpg
[18:31:49] <Tom_itx> R6 end
[18:32:46] <Tom_itx> end housings to replace bushings on some old mower starter motor
[22:05:13] <MacGalempsy_> evening
[23:53:42] <jesseg> LOL. I don't know if this kind of question is allowed, but If I'm on a budget la grande, and I need to buy a 5mm0.8 tap, would master mechanic or Irwin/Hason be better? :P LOL
[23:54:11] <jesseg> Irwin's are etched USA, master mechanic china or something
