[QUOTE="waigy, post: 495262, member: 32627"] UPDATE. I just sorted the problem of blowing fuses and the motor is rotating in the direction I want. I fitted new bearings to the motor a couple of days ago and noticed straight away that the motor was more stiff to turn and wouldn't turn freely if twisted by hand. I thought that was just the bearings being a tight fit, but I slackened the 3 long bolts that hold the whole casing together by just a touch and it loosened the shaft a lot and it now can spin freely by giving it a quick twist. It now spins for a long time after the motor is switched off which it didn't do before. So I've tightened the 3 bolts just enough to keep the motor spinning freely. But I still have the problem of the capacitor starting the motor with too much force. I have a metal tapered spindle slid onto the splined end of the shaft which is a fairly tight fit. That is then held in position by a 6mm screw to stop it rotating on the shaft. The capacitor starts the motor so violently that the 6mm screw can't hold the tapered spindle on. I have managed a work around just now of spinning the buffing wheel by hand as fast as I can, then switching the motor on while the wheel is already spinning. [/QUOTE]
