Thanks: wait, not so fast!
It was running well, until about a week ago, when all of a sudden it froze up: it was getting current, but no movement. What now? 
I thought at first it had something to do with the fact that I had attempted to center the axle gears, and in doing so, had over-compensated and that was causing the bind. So I took the whole thing apart again but it didn't seem like that was cause, as everything felt like it was ok.
I did notice that the "field winding" was getting hot, so I looked to the motor itself: I took it down to parts, cleaned everything, re-assembled, and nothing. I then thought about something I think one of you told me to look out for: making sure that the field is centered inside of the yoke.
Sure enough, if I tweaked the field a little, it would run again, so I knew that's where the problem was. I took a couple of flat toothpicks and shoved one into each side, between the field and yoke, to center it. Then tightened the screws (gently). That did the trick, so I left the toothpicks where they were (after snapping off the exposed ends) just to keep everything snug.
So there you go; thanks to you all, it's running again. Now I just need to get around to ordering that Dallee unit...
