03:51 Tom_itx that one's 3/8
03:51 rue_shop2 that could work
03:52 Tom_itx http://www.ebay.com/itm/V-Belt-V-BELT-vbelt-Singer-Juki-Sewing-Machine-3-8-x25-/250607020315?pt=LH_DefaultDomain_0&hash=item3a5957a91b
03:52 Tom_itx same.. cheaper
03:52 rue_shop2 cool

03:53 Tom_itx i stopped
03:53 rue_shop2 ah
03:53 Tom_itx i'll test it tomo...today
03:53 rue_shop2 :)
03:53 rue_shop2 you noticed its 1:30am eh?
03:53 Tom_itx i ohm tested it all though
03:53 Tom_itx i slept 3-4 hrs
03:54 rue_shop2 I'm really screwing up my sleeping schedule
03:55 Tom_itx i'm gonna try the old brushes
03:55 rue_shop2 did you know arduino is a programmer type for avrdude?
03:55 Tom_itx one was cracked a bit but i think it might wear in ok
03:55 rue_shop2 and buspirate!?....
03:55 Tom_itx yes
03:55 Tom_itx and no
03:56 Tom_itx i need a new round belt for a key cutter i have but seldom use
03:56 Tom_itx oh wait..
03:57 Tom_itx i don't need that cause i wrote a cnc program to cut keys
03:57 rue_shop2 hah
03:58 Tom_itx those belts end up the same cost about.. shipping on one free on the other
03:58 Tom_itx the first one is in LA Cali
03:58 Tom_itx the other NY
04:15 rue_shop2 bah, I'm going to sleep weather I want to or not
08:49 anton02 have any of you used robo-realm before?
08:50 iveevue What is that?
08:51 deshipu my pyboard just arrived \o/
08:55 anton02 pyboard sounds weird
08:59 iveevue deshipu, link to board site
09:04 Steffanx https://micropython.org/store/#/products/PYBv1_0 deshipu?
09:06 deshipu Steffanx: yup, that one
09:06 deshipu it's kinda expensive, but I consider it a donation for the author
11:23 GuShH Hyratel: so, the milling bed is virtually rust-free now, but it could use some resurfacing. biggest problem right now is making or finding a suitable leadscrew for the Y axis
13:39 rue_bed do you know the origional size/pitch?
13:39 rue_bed I have a bit for cutting acme, never tried it
13:39 rue_bed cause I cant do a nut
15:40 rue_shop2 ok, hmm somewhere there is a shopping list I have to deal with
17:27 rue_house I think I'v figured this out
17:27 rue_house if I have a nap, then its a new virtual day when I wake up, and I can start a new set of progress'
17:44 Tom_itx record high today 77
17:44 Tom_itx overnight 17
17:44 Tom_itx high tomorrow 39
18:22 rue_house the auto shop was able to order me in a belt
18:22 rue_house hope I asked for hte right one!
18:23 rue_house the auto glass shop did not have the clip for the window slider, the person who does it, or much interest in fixing it
18:23 rue_house so it looks like I get to do that one myself
18:23 rue_house temp is going down outside
18:24 rue_house inside toooo
18:24 rue_house maybe I should start a fire
18:24 rue_house everyone says the couch is scarry, maybe if I drag it to the middle of the livingroom and light it up, fix two problems at once
18:29 rue_house i want to build the current sense modules for the power supply next
19:06 Tom_itx now to reassemble the motor and hook it to 12v before i try the full 90v
19:20 rue_shop2 man, its cold out there
19:20 Tom_itx uh huh
19:20 Tom_itx it's headed this way with a feury
19:20 Tom_itx 35 mph SUSTAINED winds
19:20 rue_shop2 it seems I have a problem, if I build something that does not require the lathe I'm dissapointed and have to find a way to use it somehow
19:21 Tom_itx i used the drill press as a bearing press
19:23 Tom_itx if there were leaves left on the trees they'll be gone very soon
19:25 orlock rue: do you shred your wood yourself or what?
19:26 orlock i pucked up a ute load of wood from the side of the road last night
19:26 orlock interesting drive home - the ute is 4wd/fwd
19:26 orlock fully loaded it doesnt really like going or steering
19:26 orlock (no 4wd on hard surfaces)
19:28 orlock anyway, now the wood shed is overflowing
19:29 orlock i need to get a wedge and hammer
19:29 orlock i have an axe, but its a generic "axe" not for splitting wood
19:29 rue_house get an axe, its a wedge AND a hammer in ONE!
19:30 rue_house I get smaller stuff I just have to cut to length, if that
19:31 orlock rue_house: but wedge and hammer is more effecient!
19:32 rue_house so is a hydraulic gas powered splitter
19:32 orlock when we did our pre-purchase inspection, there was one in the garage.. took a moment to figure outwhat it was
19:33 rue_shop2 easy to make
19:34 orlock one day i'll get a welder
19:34 orlock i opened pone of the shed doros for the first time in a year
19:34 orlock it had been jammed shut ever since the ute decided it wanted to come inside
19:35 orlock pone? doros?
19:35 orlock me no hablo espanol
19:36 rue_shop2 setting up the tig welder: 40 mins
19:37 rue_shop2 welding the project: 2 mins
19:45 rue_shop2 number of successfull arc-starts: 3
19:46 rue_shop2 number of tungsten resharpenings: 8
19:46 rue_shop2 bzt, bzt, DAMNIT!
19:46 rue_shop2 bzt, bzt, DAMNIT!
19:46 rue_shop2 bzt, DAMNIT!
20:00 rue_shop2 there, I have a T key for the bit holder on the lathe
20:01 Tom_itx i need to make one for my mill vise
20:07 rue_shop2 I should pile up tig projects so I can do a few at once
20:08 Tom_itx or make a tig bench so you can leave it all set up
20:08 orlock whats the setup?
20:08 orlock fiddling with gas cans and loading electrodes?
20:09 Tom_itx i keep my mig tucked away in a corner until i need it
20:09 Tom_itx how's baby orlock doing?
20:10 Tom_itx spoiled rotten?
20:10 Tom_itx must be 1 or 2 now...
20:10 orlock 3
20:10 Tom_itx wow
20:10 orlock just turned 3 a few weeks ago
20:10 orlock she's awesome, though potty training sucks
20:10 Tom_itx girls are easier than boys
20:11 Tom_itx for that
20:20 rue_shop2 done without about 400psi left in the shield tank
20:42 rue_shop2 ok, I have a current sense amp to make
20:42 rue_shop2 er, supper,
20:53 rue_house 4c. maybe I shoudl start the furnace
22:40 rue_shop2 hahaha
22:40 rue_shop2 the current sense amp was out by a factor of 10
22:40 rue_shop2 scratching my head for a while, walking the circuit easuring everything
22:41 rue_shop2 then it hit me, the scope probe was switched to x10
23:03 GuShH Hyratel: update on bed http://imgur.com/a/Unbsz I almost broke that chair, doesn't look too heavy but it is!
23:03 GuShH well, not bed.. table
23:04 Hyratel that looks sexy
23:04 Hyratel also dramatic improvement
23:07 GuShH still not finished, but getting there
23:08 GuShH it is iron, so it won't shine as steel would, however I want it to remain as flat as possible so I won't touch it much
23:16 rue_shop2 looks like you have a project for a while
23:16 rue_shop2 do you know the age of the machine?
23:17 Hyratel does the True of the table matter?
23:17 Hyratel because you could coat it in a drying oil
23:21 GuShH Hyratel: it does matter, the flatter the better
23:21 GuShH and the top is referenced to the back, which is what it rides on... so
23:21 GuShH rue_house: 60-70s most likely
23:21 GuShH rue_house: biggest I could find on it's class with square / dovetail column, but we'll get a knee mill later on and I'll bombard you with more pics!
23:22 GuShH I just need a new leadscrew and it is virtually finished
23:23 GuShH rue_shop2: all bearings were replaced, they were almost all bad due to grit and grime from sitting almost outside for two decades or so
23:24 GuShH shame since they were high quality bearings
23:44 rue_shop2 drive bearings?
23:44 rue_shop2 I'd think anything to do with the leadscrews would be bushing
23:45 rue_shop2 ok, the current sensor works, now I need 2 of them
23:49 rue_shop2 ohm -r 0.1 -i 3.0
23:49 rue_shop2 Wattage is: 0.900000
23:49 rue_shop2 Current is: 3.000000
23:49 rue_shop2 Voltage is: 0.300000
23:49 rue_shop2 Resistance is : 0.100000
23:49 rue_shop2 hmmm, 1W eh?
