15:59 rue_shop2 yike
16:29 Tom_itx what are the odds...
17:15 Tom_itx so.
17:15 Tom_itx what did you get done today?
17:19 Tom_L http://www.sherline.com/dimen.htm
17:19 Tom_L what i can find on the sherline motor specs
17:19 Tom_L for sizing those pulleys...
17:19 Tom_L care to check it out?
17:20 Tom_L Output horsepower: .06 KW (60 W) at 10 oz. in. / 6100 rpm
17:20 Tom_L that's likely at the spindle
18:14 rue_house k
18:14 rue_house whats the target rpm?
18:16 rue_house hey, thats a lathe
18:17 Tom_itx i generally run around 3000
18:17 Tom_itx if i get the new belts it may run nicer at higher rpm
18:17 Tom_itx max is 5000 iirc
18:17 Tom_itx (spindle)
18:18 Tom_itx i think it will drag less with the timing belts
18:27 rue_house test
18:28 rue_house tet
18:29 Tom_itx i just re'measured the pulleys etc
18:29 Tom_itx center to center shaft distance
18:29 Tom_itx to make sure it will fit
18:30 rue_house k
18:42 Tom_itx ok they're on the way
18:45 Tom_itx really, compared to the pulleys you showed me on ebay they're just as reasonable
18:45 Tom_itx and i get exactly what i (think) i need
18:45 rue_house cool
18:45 rue_house toothed?
18:45 Tom_itx yes
18:45 Tom_itx 3mm GT2 series 9mm wide
18:45 rue_house cool
18:45 rue_house china or other?
18:46 Tom_itx GT2 makes better pulley/belt contact than other series
18:46 Tom_itx USA
18:46 Tom_itx sdp-si.com
18:46 Tom_itx local they were 1.75x as much
18:46 Tom_itx and they'd have to order them anyway
18:46 rue_house the china ones were pretty pricey, I'm not surprised if you can get soemthing at a sililar price from usa
18:47 Tom_itx i dunno, i ordered double flange on both pulleys
18:47 Tom_itx i've seen setups where just one was double flange and the other had none
18:47 Tom_itx i put double flange on my bot...
18:48 Tom_itx i don't remember what series those were though
18:48 Tom_itx i'll have to bore them both out
18:49 Tom_itx i wanted a 96 tooth belt but got a 98 since it was in stock
18:50 Tom_itx the range i measured will fit between a 89 to 103 tooth
18:50 Tom_itx to still have belt adjustment
19:12 Tom_itx gotta see if i have the right reamers now
19:50 e_house wake
19:50 rue_house !?!
19:50 rue_house maybe I'd better turn in
20:09 Tom_itx making a puller for the motor pulley now
21:23 Tom_itx ok well that was a complete waste of time.
21:23 Tom_itx i made the puller and pulled it off after backing off the grub screw to find out that there was a double grub screw in the friggin hole
21:24 Tom_itx one butted against the other apparently to keep it from backing out
21:24 Tom_itx never heard of that before.
21:25 Tom_itx the puller worked wonderfully though
21:26 Tom_itx left a nice groove in the flat of the motor shaft
21:27 Tom_itx it filed off ok though
22:54 rue_bed-aok ah, yea thats a nice trick, seen it
