[00:02:54] <asdfqwega> paul_c: I saw your post about BDI-4.08 and AMD stuff
[00:03:19] <asdfqwega> I don't know if it's any help, but I'm using your .debs on a Duron 600
[00:04:37] <asdfqwega> It's an older Asus A7V mobo that I had tried to use for a jukebox, but couldn't.
[00:04:56] <paul_c> As long as /proc/cpu doesn't report K6 or K7, it should be OK. ('cept for the homing bug)
[00:04:58] <asdfqwega> Any soundcard I put in it gave it fits.
[00:05:12] <asdfqwega> I'll check
[00:05:30] <paul_c> * paul_c disappears for 30 mins.
[00:07:00] <asdfqwega> CPU family: 6
[00:07:07] <asdfqwega> model: 3
[00:07:24] <asdfqwega> model name: AMD Duron
[00:08:02] <asdfqwega> I guess I dodged that bullet :)
[00:08:27] <anonimasu> :)
[00:10:11] <asdfqwega> Time to go hopper shopping / skip diving
[00:10:33] <asdfqwega> Need to dig out my flak jacket and hardhat, first
[00:10:56] <anonimasu> :]
[00:11:05] <anonimasu> haha flak jackets are good
[00:14:19] <A-L-P-H-A> stuck... need to get low profile #8 Socket Hex Head cap screws, that are about maybe 1" ro 1.5" in length. horray... and #8 nuts. [should have made the part bigger, so I could use what I have.
[00:14:32] <anonimasu> :(
[00:16:30] <anonimasu> a-l-p-h-a: what are you making?
[00:16:38] <A-L-P-H-A> :)
[00:16:54] <A-L-P-H-A> umm... nuk-E-lar bomb.
[00:16:55] <A-L-P-H-A> :)
[00:17:02] <anonimasu> haha
[00:17:13] <anonimasu> what do you mill uranium with?
[00:17:17] <A-L-P-H-A> I'm making an brack/spindle assembly for an rotary axis for my lathe.
[00:17:24] <A-L-P-H-A> uranium is soft. :)
[00:17:25] <anonimasu> ah ok
[00:17:35] <anonimasu> ah I havent machined that stuff..
[00:17:39] <anonimasu> I hear it's nasty for your skin
[00:17:40] <anonimasu> :D
[00:17:44] <A-L-P-H-A> http://www.lloydleung.com/EMC
[00:18:16] <A-L-P-H-A> I just finished the spindle portion of the thing... I'll photo it, and put it up.
[00:18:23] <anonimasu> ok
[00:18:27] <anonimasu> I'll look after I've had my shower
[00:19:10] <A-L-P-H-A> 'ight... in the mean time I'll create a nice backdrop for m part to be photographed. :)
[00:36:16] <anonimasu> iab
[00:36:16] <anonimasu> :)
[00:36:43] <anonimasu> I ordered a boring head today :)
[00:46:47] <A-L-P-H-A> uploading them now.
[00:50:00] <A-L-P-H-A> another 10 megs to upload.
[00:50:02] <A-L-P-H-A> :(
[00:53:27] <A-L-P-H-A> http://lloydleung.com/EMC/2005_01_19/
[00:57:58] <A-L-P-H-A> anonimasu, that was the link, if you wanted tosee. it's going to go all together with a bracket (yet to be made) to fit on my lathe's spindle, so I can have a rotary axis.
[00:59:35] <anonimasu> ok
[00:59:39] <anonimasu> I'll check it now
[00:59:43] <anonimasu> I'll be going to bed afterwards
[01:00:36] <anonimasu> very nice :)
[01:02:21] <paul_c> good evening Seattle
[01:02:38] <A-L-P-H-A> paul_c, so no hold ups in customs paul_c?
[01:03:09] <paul_c> wil let you know tomorrow.
[01:03:14] <anonimasu> :)
[01:34:27] <gezr> oh my gosh, I must get my bike back together and working, after seeing the turbo charged things videos its a must
[02:10:16] <CIA-temp448> CIA-temp448 is now known as CIA-9
[02:53:09] <paul_c> paul_c is now known as who_me
[02:53:14] <who_me> who_me is now known as paul_c
[08:59:23] <anonimasu> gezr: turbocharging it?
[11:26:32] <alex_joni> hello all
[11:27:03] <anonimasu> hello
[11:27:19] <alex_joni> hey an0n... what's up?
[11:39:27] <CIA-temp309> CIA-temp309 is now known as CIA-temp969
[11:39:32] <anonimasu> not much working
[11:39:55] <anonimasu> coding and thinking about a design of a supercharger housing, I finally found a good source for precision made gears..
[11:40:55] <anonimasu> and
[11:41:13] <anonimasu> and I've got a good design of the suport bearings aswell
[11:42:55] <anonimasu> the only problem will be that I might need ceramic bearings..
[11:43:06] <alex_joni> I see...
[11:43:21] <anonimasu> the max speed of the impeller will be about 25000rpm..
[11:44:30] <anonimasu> so finding any bearings might be a bit hard..
[11:45:07] <alex_joni> * alex_joni has also problems finding bearings, linear guides
[11:45:13] <alex_joni> rack and pinions, etc
[11:45:15] <anonimasu> yeah
[11:45:25] <anonimasu> we deal with skf at work so I can get bearings :9
[11:45:27] <anonimasu> but they are pricey
[11:45:31] <anonimasu> most likelyu
[11:45:36] <alex_joni> yeah...
[11:45:42] <anonimasu> I could go for oil film bearings.. but that solution sucks.
[11:45:49] <alex_joni> well.. better pricy but good ;)
[11:46:02] <anonimasu> I have too small shaft area to support that arrangement
[11:46:15] <anonimasu> I'd have to make the housing in 3" alu
[11:46:40] <anonimasu> and that still wouldnt solve the load issue the helical gears will have..
[11:47:13] <anonimasu> :)
[11:47:30] <anonimasu> the same oppinion as I have..
[11:47:41] <anonimasu> it's not for anything production wise, so the bearings can be pricey..
[11:50:28] <alex_joni> yup...
[11:50:28] <alex_joni> but I wanna design a plasma-cutter
[11:50:28] <alex_joni> still gotta learn a bit about mechanics
[11:50:28] <anonimasu> :)
[11:50:28] <alex_joni> and.. the final product needs to be cheap
[11:50:39] <alex_joni> so I can't choose pricy guides, racks, etc
[11:50:46] <anonimasu> I found a good company over here..
[11:50:53] <alex_joni> yeah?
[11:50:53] <anonimasu> the rails they sell are cheap..
[11:50:58] <alex_joni> got a link?
[11:51:09] <anonimasu> http://www.solectro.se
[11:51:20] <anonimasu> the expensive things are the carridges..
[11:51:45] <anonimasu> although not that expensive..
[11:52:27] <anonimasu> and they are in swedish :/
[11:52:43] <anonimasu> "mekanik"
[11:52:43] <alex_joni> I am a distributor for some swedish machines...
[11:52:49] <anonimasu> is where you want to go
[11:52:51] <alex_joni> SPT if you know them
[11:53:11] <anonimasu> http://www.solectro.se/Products/Category.asp?SectionId=854
[11:53:15] <anonimasu> never heard about them
[11:53:22] <alex_joni> plasma cutting
[11:53:28] <anonimasu> nope :(
[11:53:54] <anonimasu> there you have what you are looking for
[11:53:59] <alex_joni> yeah
[11:54:21] <anonimasu> they dont have prices on the web though..
[11:54:35] <anonimasu> but if you write down their part numbers I could check the catalog for you
[11:55:20] <anonimasu> the carriges are about 200$
[11:55:30] <anonimasu> most of them
[11:57:27] <alex_joni> I'm not very fond of those alu-extruded profiles
[11:58:41] <anonimasu> they have rails aswell.. somwhere..
[12:00:49] <anonimasu> or do you mean thoose that you build stuff in?
[12:01:07] <alex_joni> hmmm... seems I found a distributor in Romania for Rollon
[12:01:12] <alex_joni> http://www.rollon.com/
[12:01:33] <anonimasu> nice :)
[12:01:54] <anonimasu> I wish I could find somone that could cast me a machine base :]
[12:02:10] <anonimasu> in epucrete.de or somthing like that
[12:03:42] <anonimasu> building a stiff machine in somthing like that wouldnt be too hard
[12:05:11] <anonimasu> oh cool rollon is in sweden aswell
[12:05:40] <alex_joni> yes?
[12:05:48] <alex_joni> don't know how good they are thou...
[12:06:18] <anonimasu> if I were to build a machine from scratch, I'd go with skf..
[12:06:25] <anonimasu> but well, I could never afford SKF rails.
[12:06:32] <anonimasu> :)
[12:06:36] <anonimasu> not right now that is..
[12:07:08] <anonimasu> skf has insane precision on their stuff :)
[12:07:24] <anonimasu> unmeasurable backslash in screws.. :)
[12:07:31] <anonimasu> err ballscrews..
[12:07:37] <anonimasu> although by my means that is..
[12:10:23] <alex_joni> I like UNILINE
[12:10:30] <alex_joni> what do you think of those... ?
[12:10:39] <anonimasu> never heard of :9
[12:10:40] <anonimasu> :)
[12:10:51] <alex_joni> from rollon, one of their products
[12:10:56] <alex_joni> http://www.rollon.com/english/products/uniline.htm
[12:11:00] <anonimasu> ah
[12:11:15] <anonimasu> btw, what are your precision needs?
[12:11:25] <alex_joni> for plasma?
[12:11:35] <alex_joni> around +/-0.1 mm would be more than enough
[12:11:43] <anonimasu> ah ok
[12:12:04] <anonimasu> anything from rollon would probably be good then
[12:12:11] <anonimasu> anything sealed that is..
[12:12:39] <alex_joni> yup.. that's what I thought too
[12:13:03] <alex_joni> I like uniline
[12:13:11] <alex_joni> I would put a DC motor on one side
[12:13:14] <anonimasu> * anonimasu thinks about 0.003 repeatability when thinking about rails
[12:13:28] <anonimasu> nice
[12:13:35] <anonimasu> ungeared?
[12:13:36] <alex_joni> and a encoder on the other side
[12:13:41] <alex_joni> geared
[12:13:45] <anonimasu> ok
[12:13:57] <alex_joni> I have some nice 100W motors (used for wirefeeders on the MIG stuff I have)
[12:14:07] <alex_joni> 42V DC
[12:14:16] <anonimasu> if you are building a large gantry you will need to drive em from both sides..
[12:14:25] <alex_joni> yeah...
[12:14:33] <anonimasu> I talked to some enginner a while back about it..
[12:14:38] <CIA-temp435> CIA-temp435 is now known as CIA-9
[12:14:44] <alex_joni> how about a rod between the two sides
[12:14:46] <alex_joni> ?
[12:15:04] <anonimasu> you mean and drive the both sides with one motor?
[12:15:10] <alex_joni> yup
[12:15:15] <anonimasu> that'd work..
[12:15:16] <alex_joni> if the motor handles the load
[12:15:21] <anonimasu> yep
[12:15:26] <alex_joni> take a look at uniline.htm
[12:15:32] <alex_joni> there's a sample app there
[12:15:40] <alex_joni> plasma cutting ;)
[12:16:04] <anonimasu> looks really nice
[12:16:45] <anonimasu> I am kind of curious about the price
[12:16:46] <anonimasu> :)
[12:17:09] <alex_joni> me too
[12:17:11] <anonimasu> it's a nice deal when it's belt driven aswell..
[12:17:29] <alex_joni> I wasn't so enthusiast about belt drive... but if it works ;)
[12:18:25] <anonimasu> for about $800 per side for a longer screw I bet it'll rock :D
[12:18:34] <anonimasu> I dont know if that's enough for ballscrwes..
[12:18:37] <anonimasu> screws..
[12:18:45] <alex_joni> screws are not an option
[12:18:48] <anonimasu> yeah :)
[12:18:54] <alex_joni> too expensive for long ones
[12:19:03] <alex_joni> if I want to extend the machine to 2x12...
[12:19:14] <alex_joni> don't think I'll find a 12m screw D:
[12:19:15] <alex_joni> :D
[12:19:24] <anonimasu> haha
[12:19:25] <anonimasu> yeah
[12:19:27] <anonimasu> exactly
[12:19:41] <anonimasu> belt drives handle dirt better then screws aswell
[12:19:46] <alex_joni> belt neither
[12:19:59] <alex_joni> so I think the only thing would be rack & pinion
[12:20:06] <anonimasu> oh, I think they sell that long belts..
[12:20:07] <anonimasu> :)
[12:20:20] <alex_joni> but I'm not sure how elastic they are at 12m
[12:20:25] <alex_joni> and what precision you get
[12:20:43] <anonimasu> they dont flex that much if they are dimensioned for it
[12:20:56] <alex_joni> you think?
[12:21:17] <anonimasu> not that awfully much
[12:22:19] <anonimasu> I was surprised on how they were on my mill.. but that's not 12m
[12:22:56] <anonimasu> btw, isnt thoose uniline units with belts and all included?
[12:23:29] <alex_joni> yup
[12:23:34] <anonimasu> :)
[12:23:52] <anonimasu> then they will probably be good enough up to the max length they sell them at
[12:24:54] <alex_joni> that's what I'm searching now
[12:24:56] <anonimasu> we had some belts from a company for driving a compressor on a machine... toothed belts that would handle a couple of 1000N's ;)
[12:25:05] <alex_joni> jeee...
[12:25:06] <alex_joni> ;)
[12:25:35] <anonimasu> about 7000
[12:25:57] <anonimasu> but the length is the problem..
[12:26:19] <anonimasu> the company I buy stuff from has lengths up to 2m on warehouse..
[12:26:29] <alex_joni> I have no idea what N's I'd need :(
[12:26:33] <anonimasu> err 4m for some small ones
[12:26:44] <anonimasu> probably not that much
[12:27:03] <anonimasu> since you drive both sides that reduces the load on each side.. aswell
[12:27:20] <alex_joni> yup...
[12:27:28] <alex_joni> no idea how to calculate it though...
[12:27:34] <anonimasu> * anonimasu neither
[12:27:45] <anonimasu> brb need to work a bit
[12:28:26] <alex_joni> ok.. later ;)
[12:29:56] <CIA-temp158> CIA-temp158 is now known as CIA-5
[13:53:17] <CIA-temp934> CIA-temp934 is now known as CIA-9
[16:02:14] <alex_joni> * alex_joni goes home
[16:02:16] <alex_joni> bye guys

[21:23:15] <robin_sz> eveny
[21:30:54] <gezr> howdy
[21:31:34] <gezr> anonimasu : no im not turbocharging mine
[21:31:53] <gezr> anonimasu : oh and on a side you were saying yesterday your ball screw pitch is 2mm?
[21:35:23] <anonimasu> gezr: I said 5mm..
[21:35:51] <anonimasu> gezr: if I wrote 2 that's a typo.. :)
[21:36:01] <gezr> i was just thinking about it at work
[21:36:06] <gezr> I wasnt sure
[21:36:30] <gezr> so you get like what was that number .002mm resoultuion at 2000cpr?
[21:36:46] <anonimasu> I gear that 4:1
[21:37:11] <anonimasu> 2 was my spindle hp :9
[21:37:12] <anonimasu> :)
[21:37:33] <gezr> so 4 of the servo to 1 of the screw?
[21:37:54] <anonimasu> no.. 1 servo to a toothed belt
[21:38:10] <gezr> ah, servo one time, screw 4 times
[21:38:16] <anonimasu> opposite..
[21:38:31] <anonimasu> servo 4 times screw 1 time I have tiny servos :)
[21:38:37] <gezr> haahahah, 4 servo one screw, ah okay
[21:38:50] <anonimasu> 4:1 ratio ;)
[21:40:21] <anonimasu> But I dont run em on full resolution right now that gives me a too slow speed to be acceptable..
[21:40:39] <anonimasu> err I use the multiplier of the geckos..
[21:40:44] <anonimasu> g340's..
[21:43:18] <A-L-P-H-A> it's SOOO nice to be a regular at a place you buy tools. They know me by name, and yet I don't know theirs at all. But they give me discounts, and don't charge me tax. :) I love them.
[21:43:30] <A-L-P-H-A> Nice old ladies that work there...
[21:44:29] <anonimasu> haha
[21:44:30] <anonimasu> neat
[21:45:08] <A-L-P-H-A> I get a quoted price from them... and when I get it, they charge me even less. :)
[21:45:30] <anonimasu> haha
[21:45:32] <anonimasu> very nice
[21:46:02] <A-L-P-H-A> so far this whole bracket assembly thing, I think I've spent... around $100 bucks, in new tools, and materials and parts.
[21:46:06] <A-L-P-H-A> Canadian.
[21:46:17] <A-L-P-H-A> and I think $70 of that was on the worm and wormgear.
[21:48:02] <anonimasu> :)
[21:48:04] <A-L-P-H-A> $8.75 on an drill bit... used 6" on a 3ft segment of O1 drill rod. And stock material I have kicking around.
[21:48:17] <A-L-P-H-A> the whole drill rod was $25 for 3ft.
[21:49:00] <gezr> cool
[21:49:08] <gezr> got off easy at the store :)
[21:49:19] <gezr> i pretty much have to order what I may need
[21:49:29] <gezr> I love to touch stuff too
[21:49:47] <A-L-P-H-A> The stock that I have came with this home shop this I knew was selling.
[21:49:53] <anonimasu> hehe
[21:50:44] <anonimasu> I need to leave for a bit
[21:50:49] <anonimasu> I'll be back soon
[21:50:53] <A-L-P-H-A> so I have a Schaublin 102 lathe (cnc'd already), a crappy benchtop mill that I've converted [which I need to fix], two rotary grinders, a medium duty mig welder with ArCO2 bottle that's full, a drill press, TONS of tooling, and TONs of alumium, and brass stock. :)
[21:52:01] <anonimasu> :)
[21:52:01] <anonimasu> nice
[21:52:11] <gezr> nice indeed
[21:52:20] <A-L-P-H-A> all for a very sweet deal... $4.5K Cdn.
[21:52:26] <anonimasu> that's a good deal
[21:52:43] <A-L-P-H-A> I sold off the old controllers, and made my own...
[21:52:58] <anonimasu> brb
[21:53:17] <A-L-P-H-A> oh yeah, I got tiny little air compressor which I sold off as well.
[21:54:17] <A-L-P-H-A> what else? hmm... gear cutters, carbide indexable turning tools, a very nice collet set for the mill. a few stepper motors... a bunch of different sized endmills.
[21:54:24] <gezr> I need a vertical mill, my little horizontal doesnt hardly ever get used
[21:54:37] <gezr> yummy gear cutters
[21:54:39] <A-L-P-H-A> so, all in all, a NICE hual.
[21:54:54] <A-L-P-H-A> yeah, I've got a sandwhich bag full of gear cutters...
[21:55:11] <A-L-P-H-A> i don't make gears... so I don't know what to do with them. :)
[21:55:12] <A-L-P-H-A> hehe.
[21:56:00] <A-L-P-H-A> I want a 12x19" benchtop lathe...
[21:57:36] <A-L-P-H-A> nice thing is, I've made my money back on the toys already. :)
[21:57:54] <A-L-P-H-A> so everything else is gravey now... make money to buy more toys for it.
[23:03:42] <gezr> hllo, sorry I was on the pone getitng some stuff for my bike
[23:59:40] <robin_sz> meep?
