On your last picture you show the motor with a little rubber on the end - that is what drives that machine. You can get some shrink stuff at the hardware store's electrical department to go on the end of that - replace the rubber. Does the motor try to go at all??? Motors can be rebuilt if necessary. Bennett has a tutorial on rebuilding a motor. There are motor rebuild shops that can rebuild your motor if it you don't want to do it. Very mid-century modern looking machine and table. They must have been trying to get them more efficient about that time.
