Okay, certainly not the best suggestion you're going to get, but you brought back a fond memory . . .
When I first started quilting in the 90's, my MIL generously gave me her old sewing machine. It was a Singer behemoth, green metal, in a cabinet. The first thing to die was the bobbin-winding capacity, and it couldn't be fixed (again). Rather than have me hand-wind bobbins (there was no such thing as a Sidewinder in those days), husband got out his electric screwdriver. He put the bobbin on top of the screwdriver & held the thread in the other hand, feeding it gently & trying to distribute the thread evenly over the bobbin. He did that for several years, until we could afford a new machine. Such a patient, supportive husband! Thanks for the fond memory! Kathy B.
