Update! Update! Hubby applied man hands to the stop motion knob & got it to turn! Yip, yip, yahoo! I like to think it turned at least in part because of all the lubricating i've done. Anyway. Unfortunately, when I run the machine it still makes kind of a grindy noise that seems to be coming from the gear I can see looking down into the machine that's attached to the flywheel & stop motion knob. Should I try to take off both those knobs and find more things to oil there? Will I destroy the machine if I take those off? If I can get them off. Thanks so much for all your help!
