I need some assistance in properly wiring up this motor. I am thinking of setting it up as a 'Foredom' type tool. I've got a few hand pieces and am hoping I can get one to work for polishing wheels. The motor has been kicking around for over 20 years, and I even forgot I had until I was unpacking an old box of clutter. Firing it up 'as-is', it spins up nicely. However there seems to be a 50-50 chance of which direction the shaft will rotate. The labeling states CCW but it is going in both directions. I figure that I need a capacitor or something a bit more than just an extension cord spliced to it. Thanks!
