I have been using a Centennial Featherweight and just recently started having trouble with it. The thread jumps out of the bobbin case. I cleaned everything, took the upper tension apart and cleaned that. I thought everything was back to normal. It didn’t take too long until the thread started jumping out of the bobbin case again. I didn’t realize it was happening until I noticed the top thread was very tight and I could just slide it out of the line of stitching.

I am going to try a different bobbin case to see if that will help, but I would like to fix this one also, if the bobbin case is the problem.

Does anyone have any ideas about why this is happening and what to do to prevent it?

The screw to tighten the tension is too tight to tighten that. I cannot pull the thread out of the guides in the bobbin.

Thanks, Pam
