Bobbin does not fill completely

Verify that you are threading the machine correctly for bobbin winding. Slow down the speed of winding.

I know this sounds like an insult, but check FIRST to be sure you have the bobbin inserted in the bobbin case correectly. If it IS in the case right, then check your upper tension. It generally needs to be at 3. Check also to be sure the top thread is between the tension disks. If it isn't, you won't have the right tension to connect the threads. You bobbin also needs to be wound tightly. A loose wind will cause problems with the bobbin thread. If none of these work, the bobbin tension might need to be adjusted by a professional. I hope one of my suggestions helps. If so, please let Fixya know by rating my solution.

This may help you with the threading and bobbin winding - http://www.suite101.com/reference/how_to_fill_the_bobbin_on_a_featherweight

go to the nearest singer sewing machine store. get some assistance.

After you put the bobbin on, push it over to the right. It should slide into position so that it spins correctly and winds the thread.

Sounds like it is out of time. I recommend you take it to your local repair center.

slide plate may be worn - i had the same problem. try holding down the center of the bobbin with a pin while slide plate is in the winding position.
