White Rotary Bobbin Issue
Help. I have a White Rotary, approx 1920's, Krinkle finish. I cannot get the needle to catch the bobbin thread. I have been sewing 50 years, I know most issues, but this one eludes me. It's threaded correctly. Bobbin threaded and inserted correctly. Tension adjusted. Bobbin winder is disengaged. Tried several needles. Bobbin area is cleaned. Bobbin does not wobble. I know which way to turn the wheel. Have taken apart and reassembled bobbin several times. I'm at a loss as to why the needle won't grab the bobbin thread. It came with extra needles. Two are really long, tried one but it is too long and hits the bobbin threaded on the spool rather than catches it. Tried 3 of the 4 normal sized needles with no luck. They seem to be too short, but maybe that's just my eyes. Otherwise it works great. Any suggestions would be appreciated.
