Thanks everyone....I gave it a shot....but this machine is retiring for good. The rubber feed dogs look terrible, so they probably need replaced, but I started cleaning it, and pulled lots of "goo" out from under the bobbin casing...I think my FIL must have tinkered with it at some point and used automotive oil in it or something!!! I have 2 great machines, and a few other vintage machines waiting for some tlc. Time to move on!
