I replaced the cap with a Cornell Dubilier 108-130 MFD 125V cap. It seemed better, but then tripped. There aren’t other caps that I see, so it sounds like a failure in the motor itself. I don’t see any point in trying to save a 70 year old motor, but am open to suggestions.
I need to decide if this machine is worth saving. I’d like to, but once the shutoff is solved, I need to address the runout, and the plan for that is to send the quill and spindle to a guy who will rehab them for $150. Looks like a motor is $150. So, that’s $300 to rehab a 14″ floor-stand drill press.
