Bobbin wheel not in contact with Handcrank wheel?
I bought this machine, and my quarantine project has been restoring it. I've never had an antique machine before, so I'm not super well-informed on how everything is supposed to work.
The bobbin wheel is not in contact with the hand cranked wheel. In order to wind the bobbin, you have to tip the wheel up using your hand. I have tried tightening and loosening the screw for this to adjust the angle and I cannot get the bobbin to stay in the position where the wheels contact, it just drops back down.
The machine is a Singer 187K from 1901.
Do these two wheels always need to be in contact with each other when sewing, or just when winding the bobbin? And, if so, is there a way to fix it?
