some must have experimented this at least once?

 

I dont see why you couldnt i always polish cranks when i put in new bearings since it only 25 buck at a local shop here. They do it with a cork band

 

so u have polished your e-shaft correct?

 

No just piston cranks but i see no reason why not. Your not taking any material away just any minute imperfections
