I am brand new to lumberjocks and consider myself a very amateur woodworker. I love the older, mostly pre-70’s tools. I recently purchased a Craftsman 103.23320 jointer. It is in good shape, and except for some surface rust on the tables, it mostly just needs lubrication to loosen things up. While I was checking it out, before buying, we had the motor running (it was not attached) and it seemed to run well with very little noise. After about 5 minutes, it began to smoke slightly and suddenly began to throw sparks from inside. We shut it down. I noticed afterwards I could barely turn the motor shaft by hand whereas before, it turned smoothly. Considering that, the owner dropped the price to $30 and I brought the jointer home. The motor is a Craftsman, 3/4 HP capacitor motor, ball bearing, 3450 RPM, 115 volts, 60 cycle, 9.3 amps. What are my options with this motor? It looks like the original motor so I would like to restore but I am also on a limited budget. Any advice you can provide would be greatly appreciated.
