or you could stuck some assorded stuff into the motor to jam the rotors and use the lathe as normal. Please don't try either of these things.
Seriously though, we need some help here.

The first thing (4 steps) might actually work. But I don't recommend it unless you have a spare. I would not try the second thing (jam the motor) at all. With pretty much anything other than pressing or pulling, you run the risk of getting metal chips or dust in the motor which coule run the bushings, cut insulation on the windings, and/or create a catasrophic electrical short.
I had an RC airplane motor with a pressed gear that I wanted to get off. I tried heating it up, that didn't work. Then I tried holding the gear (with a custom little plate) and tapping the motor back through it. That didn't work. Finally, I tried sticking a little piece of plate or little pliers or something in between the back of the gear and the front of the motor and using it like a lever prying the gear off the shaft. This worked. Now, this was a junk motor I was getting the gear off of, so I can't really say how the motor stood up to my torture, but the gear came out pretty much fine.
If you don't have a press or don't know how to set it up in there, you could try the leverage thing. That is the next least risky. But I really don't know how tight that gear is on there. In any case other than a strait press off, you should be at least prepared to get a new motor if something goes wrong. I have a link of where to get it if you need it.
I wonder if we sang songs to Bill Miller if that would get TIMS opened sooner, like the way it worked to wring game hints out of Dave Laverly. - rsisk [more]
