I had to cut down a stepper motor shaft from 1/2" to a little less than 3/8" to fit an encoder. The motor had 1/2" shafts on both ends. The motor was a nema 34 with flying leads. I taped the leads to the body of the motor. I chucked the 1/2" shaft I did not want to machine in the 3 jaw chuck. I

Assuming the bearings come off, maybe dip the end you are machining in hot paraffin? After it sets up it should make a fair chip dam. On Mon, Sep 7, 2015 at 11:56 AM, rayj wrote: > Someone mentioned using modelling clay for removing chips from magnets > on this list earlier. > > I was thinking:

Someone mentioned using modelling clay for removing chips from magnets on this list earlier. I was thinking: Wrap it with cling wrap or maybe cover it with grease so the clay doesn't adhere and then cover it with clay. When finished, press all the swarf firmly into the clay and then remove the

I have a motor that would be about right for my lathe conversion, if it didn't have a brake on the back. (a nice short motor is useful for a Lathe X axis). I am considering re-machining the rotor shaft and the end cover to make it into a shorter motor without a brake. The problem, clearly, will b
