Singer 30920 I just bought this old machine and it was supposed to work, but I can't seem to get it figured out. It has one of those black plastic bobbin cases with a drop in bobbin, and I wondering if it takes a special bobbin, because when the top thread wraps around, the bobbin it catches the top lip of the bobbin and wraps around it, instead of sliding over the top. Any help would be great, I'm stumped.

Bobbins are specific to machines.........if you are trying to use a non-singer bobbin, the diametre and depth may well be several millimetres different and will result in what you describe.

Ask for plastic singer bobbins for a top loader......if you contact Singer or an agent, they will give you a part number and will probably ship to you as well.........get a few and have all your colours ready, not all layered on just a couple !
