[[user:aaron|aaron]]: Took apart all the mechanics (with the exception of the spindle itself), cleaned/re-oiled everything, and put it back together. The leadscrew mechanism was quite stiff, but rotates a lot more freely now. I had to very slightly file down the edge of one of cog shafts, which seemed to have flared out a bit and was sticking. I've left it covered by a tarp, with the motor removed. | [[user:aaron|aaron]]: Took apart all the mechanics (with the exception of the spindle itself), cleaned/re-oiled everything, and put it back together.

The motor itself still has the problem of tripping the circuit breaker, and at low revs has a very noticable sparking around the commutator. Apparently there are lots of ways to mess up a motor when trying to clean it, so we should be careful. See [http://www.chaski.com/homemachinist/viewtopic.php?f=4&t=81428 this forum thread] for one potential cause of sparking and things not to do when trying to fix it. | The motor itself still has the problem of tripping the circuit breaker (it hasn't magically healed itself), and at low revs has a very noticable sparking around the commutator.
