problem winding featherweight bobbin
I have a featherweight identical to the one in this image. [ATTACH=CONFIG]507152[/ATTACH] When I try to wind the bobbin, after pulling the mechanism down into contact with the belt, the slick black plastic wheel slips against the leather belt making sporadic, incomplete contact. The bobbin spins in fits and jerks instead of smoothly. What to do?
Yes, the mechanism is all the way down in contact with the belt. Yes, I have disengaged the fly wheel.
