Every now and then the bobbin thread would break, a be tight at the "top" end of the bobbin. It felt "notchy" when pulling the thread through the bobbin. I felt the bobbin for burrs or rough spots and there weren't any. Bobbin winder seemed to work well. Looking in the bobbin case, I saw deep down in the bottom, a partial disc of "felt". I wondered if it was supposed to have a full one, hadn't read any where that there should be. Checked my other bobbin case, and it had a complete disc of "felt". So I pulled out the partial one, and PROBLEM SOLVED! It now pulls nice and smooth. So I pulled the "felt" out of the other case also. Yeay, progress...I think...

Do you suppose someone used some bobbins that were just a bit shorter than the Singer bobbins, and used the felt to make up the length difference?

I have cleaned a lot of lint and fuzz out of the shuttles for my machines but I've never seen one with a felt disk in it. If it wasn't a build up of thread lint I'd be agreeing with CD that someone tried to compensate for a too short bobbin.

If I remember right, it DID come with the shorter bobbins. However, it was it the shuttle cases from 2 different machines, purchased from different sellers, at 2 different times. Pretty sure what I was seeing was compacted lint. I've since gone in there with toothpicks and q-tips to get residual gunk out of the bobbin cases.
