I'm not sure about the first one. I may have a friend look it over. If the motor is bad I wouldn't know what to do about that. And the rubber thing that moves the wheel is worn out pretty bad. I have a PM to Billy to see what his opinion is. I did find a book online about this machine for $17 so may get it. I haven't looked for a book on the grand rotary. It runs so well, though! I will look for one, I'm sure. LOL!
