Problem- Shorten the shaft of a servo??

[JerryFlyGuy]

Well guy's I've got one that I've never had before. I've got a MCG servo which has too long of a shaft. When I try and assemble it w/ my gear reducers, the pinion on the reducer won't fit all the way into the housing [it bottoms out] and there is ~1/8" of a gap between the motor and reducer flanges.

I'm tempted to take this servo over to the shop and mount it in our band saw and just take ~1/4" off the end of it.. while holding the shaft still w/ a pair of plyers..

Is there an easier/better way? I've never had to shorten a motor shaft before!

You could try the method I used once on a motor shaft. Wire it up, turn it on, pick up a hacksaw and use it as a kind of parting tool on the spinning shaft. Worked like charm.

We are supposed to get your leftovers!!

One method I have used if you have a rear shaft also, is to hold the rear shaft in the chuck and the front shaft in a tailstock centre and tie the motor body to stop it turning.
An slice it off almost all the way through.
I prefer to hold the cut end in the chuck, but you do not have much to play with.
