Wow, you stole it. Congrats. Clean it well and check those gears.
Pat, I've had to remove the guts of this machine before to repair a loose knob that could only be reached by removing the cam follower mechanism and drive shaft. What a pain. I've also had to replace motor brushes and had to invent a technique so I wouldn't have to remove the bottom of the machine. Replacing motor brushes on it are not easy! I do agree with Miriam that it's not a beginner machine and I suspect the amount of people that will tackle these old gals dwindles by the day. They are not intuitive or easy to work on. I would suggest you keep your eye on ebay or CL for a donor machine to start with. Then, at least you'll have the parts to work with and then you can attempt to find someone who knows what they're doing.
