15:47 Tom_L for me.
19:37 rue_shop2 ran out of diesel trying to cast something today
19:38 rue_shop2 but at the same time, it seems something might have goten jammed in the blower
19:38 rue_shop2 have to check it out tommotor
19:38 rue_shop2 tommorow
19:38 rue_shop2 tommorow is last vaccation day
19:38 Tom_itx rue_shop2
19:39 Tom_itx i pressed the bearings back in
19:39 Tom_itx i applied 12v to the motor......
19:39 Tom_itx ...
19:39 Tom_itx ...
19:39 rue_shop2 ...
19:39 Tom_itx ...
19:39 Tom_itx it works!
19:39 rue_shop2 yay!
19:39 rue_shop2 smooth?
19:39 Tom_itx don't do that again!
19:39 rue_shop2 no cogging?
19:39 Tom_itx no it's fine
19:39 Tom_itx both ways
19:39 rue_shop2 lucky dude
19:39 rue_shop2 you are
19:39 Tom_itx once i got 2 wires i could see a pattern
19:39 Tom_itx and followed it
19:40 rue_shop2 yup
19:40 Tom_itx good experience really
19:40 rue_shop2 you gonna line up to find another motor as a spare?
19:40 Tom_itx already did
19:40 rue_shop2 cool
19:40 Tom_itx the bearings aren't that good in this one
19:40 Tom_itx it will become the spare probably
19:41 rue_shop2 you changed them, right?
19:41 Tom_itx no
19:41 Tom_itx the front one isn't replaceable
19:41 Tom_itx it's pressed in and has a washer on the inside that's swedged in place to hold it all in
19:42 Tom_itx i didn't take pics this time
19:42 Tom_itx the rear bearing i could get out but it was the front one that was noisy
19:43 Tom_itx some of the wires to the commutator were a bit short but i was able to solder them
19:45 Tom_itx would it make a generator?
19:46 rue_shop2 yup
19:46 rue_shop2 permantent magnet motor I presume
19:47 rue_shop2 not a wound field
19:47 Tom_itx yes
19:47 Tom_itx permanent magnet
19:47 Tom_itx hooked to the control it drags when i try to turn it backwards
19:48 rue_shop2 most of th time the brushes get or are set to an angle that make forward hapier
19:48 rue_shop2 oh,
19:48 rue_shop2 nevermind
19:48 Tom_itx yeah i'm sure
19:48 Tom_itx they look pretty square though
19:49 Tom_itx would the timing be 0 if the brushes centered on the commutator winding?
19:49 rue_shop2 possibly are, its rare to see a motor thats optimized or worn in to work one way better than the other
19:49 rue_shop2 its all about the windings/brush angle/field angle
19:50 rue_shop2 so, I cant say much
19:50 Tom_itx the replacement has external brushes i think
19:50 rue_shop2 I should get my old cnc happier
19:50 Tom_itx yes you should
19:50 rue_shop2 or finish my new one
19:50 Tom_itx 2.6.4 is out now
19:50 Tom_itx the new iso has a USB fix on it
19:50 Tom_itx i'm still using 2.5.x
19:50 rue_shop2 I'v been getting a itch to make a small ridgid cnc mill
19:50 Tom_itx scratch it
19:51 Tom_itx i wish i had time and funds to make a heavy one
19:51 rue_shop2 cnc mill 3.0 is going to be obsolete and I'll finish 4
19:51 rue_shop2 I'm gathering ideas on making sliders
19:51 Tom_itx it's probably the thing i enjoy doing the most of all
19:52 rue_shop2 I'd buy an XY table for $100 if I heard that any of the $100 ones are worth more than scrap metal
19:52 Tom_itx i have an x y table in the attic still in cosmolene
19:52 rue_shop2 (xy tables for mutant drill presses)
19:53 Tom_itx i'm really not sure why i ever got it
19:59 rue_shop2 http://www.princessauto.com/pal/en/Vises/6-in-2-Way-Cross-Slide-Vise/8128159.p
19:59 rue_shop2 I hear they are crap tho
20:02 Tom_itx more than likely
20:02 Tom_itx i think mine was just a table
20:02 Tom_itx can't remember now
