New to me....1957 Singer 99K
I just picked up a Singer 99K for $20. It worked before I tore into it....but it was filthy. I have is apart and followed Billy's suggestions of cleaning it. The only problem is I can't seem to get the bobbin lifter, the feed dogs and the hook out. There is gobs of black gunk that I have been steadily chipping away. I took out the screw in the center of the bobbin lifter (although I am not sure that was the right thing to do), and the small screw under the hook as well as the screw under the machine that supposedly holds the feed dogs in place. Still after a kerosene soak, and WD40, I can't get the pieces to budge. Any suggestions?? Thanks, Marilyn
