I looked all over but couldn't figure out how to edit my first post, so here is an addition:
Look at this picture [ATTACH=CONFIG]511578[/ATTACH]See the gouge on the inside of the handwheel? It's about 1/8" long and fairly shallow, but it could be causing some problems. What do you think? Should I try to get a replacement handwheel? I'm thinking $80 was too much for this machine!
