A friend has acquired a really old table saw / jointer combo that was apparently made in the 1940s/1950s. The motor is a dual shaft arrangement where one side runs the table saw and the other runs the jointer. Attached to the motor is a large capacitor that sealed and painted and has no markings. The capacitor is dead and I'm trying to figure out the best size replacement and whether it was a start or run capacitor. Because of the dual shaft arrangement, I can't see an easy way to get into the motor to see if it's got a start switch and I'm at a loss how to size the replacement capacitor.
A photo of the motor plate is attached.
Edit: Included more pics of the motor, wiring and capacitor. I had to destroy the case to get into it (which I was trying to avoid), and once inside the capacitor has no markings at all on any surface.
