Bent rotor / shaft
 

My vampire motor shaft has a slight bend in it , I did it trying to remove a pinion that was stuck on , has anyone tried to straighten one ? A new one is £35 !

need special equipment to straighten something like that, at 10's of thousands of rpm the thing has to absolutely straight.

I'm afraid that probably needs to go in the £35 lesson learned drawer. :thumbdown:

I've got a new one on order from mike Parker

Unlikely you will straighten that. The are hardened shafts so require a lot of force, and you need to apply that force right where the magnet is so that could easily crack. New one... and a better pinion to go with it??!!! :)
