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.

    \$\begingroup\$ We could use extra pics of the capacitor and any labels on it, and pics of the motor from a wider view. Pics of the wiring harness as well. \$\endgroup\$ – Sparky256 May 8 '18 at 0:38
  • \$\begingroup\$ @Sparky256 - added more pics as requested. That is the only label on the motor. I destroyed the capacitor housing to get at it and there are no markings on the cap. \$\endgroup\$ – James May 8 '18 at 7:04
  • \$\begingroup\$ Honestly, it looks like something you should take out back and shoot. If it was not for the pervasive rust, it might have a chance of running again. If the insides have this kind of rust, you now have a hefty paperweight. \$\endgroup\$ – Sparky256 May 8 '18 at 7:35

    \$\begingroup\$ Measure the capacitance, or is it shorted? \$\endgroup\$ – Dirk Bruere May 8 '18 at 7:55
