02:02 GuShH_ the bearings flop about 2mm up/down in the assembly, circlip doesn't seem to be doing much
02:03 ShH_ will end up machining a thread on the shaft and quite possibly making a custom nut fo
10:21 rue_bed ANOTHER 12 hours later
10:22 Tom_itx wasted hours?
10:22 Tom_itx just finished painting the final side of the garage
10:22 rue_bed na, slept most the night on the deck, but the birds were getting noisy this morning I came in
10:23 rue_bed it was really warm out yesterday
10:43 Tom_itx gonna be warm today too
10:43 Tom_itx was ~50F when i started painting
14:58 MrCurious happy caturday!
17:36 blockh34d Me-yow
18:23 MrCurious that made my skin crawl, and not in a good way...
19:29 blockh34d sounds like you need some kitten mittens
19:30 blockh34d is there a good kind of skin crawl? lol
21:47 rue_shop2 bolts for the most part, but I keep grabbing metal to machine that hardens up really easy and starts destroying every bit that touches it
21:48 rue_shop2 I dont know if thats high or low grade metal
21:48 rue_shop2 and I tried to do a peice of stainless - fail
21:49 rue_shop2 and one of the taps I had seems to have been full of microfractures, even on someting easy after it was reground it snapped a few places
21:58 Triffid_Hunter rue_shop2: stainless is well known to work-harden :P
21:59 Triffid_Hunter if you have to cut it, go hard or don't bother but for your bit's sake don't slow down!
22:45 rue_shop2 interseting, not the oppinion I generally hear
22:45 rue_shop2 there is another metal that keeps comming up, it workhardens badly, but its not stainless
22:45 Jak_o_Shadows Doesn't copper work harden?
22:46 rue_shop2 no, copper is just evil
22:46 GargantuaSauce i think part of the answer is MOAR LUBES
22:46 GargantuaSauce pretty sure workhardening is largely a thermal effect, though the shear is also a factor
22:46 Jak_o_Shadows Nope, it's also a mechanical thing.
22:47 Jak_o_Shadows You're deforming the crystal structure of the metal.
22:47 GargantuaSauce yeah ok
22:53 Jak_o_Shadows and yeah, copper age hardens as well
22:53 rue_shop2 "WARRANTY VOID IF BROKEN" .. damit!
23:22 rue_shop2 somewhere in this shop is a rather large 3 phase motor, and I can fin dit
23:35 Jak_o_Shadows How large?
23:55 rue_more about 480 square feet
