Question about Kenmore Drop-In Bobbin 505S-21BH Mechanical Sewing Machine
I was sewing along fine for about two feet, then the needle jammed and had to be taken out. I cleaned the shuttle race and put it back in the machine (according to illustrations on p. 39 of manual). When I turn the wheel by hand w/o using the foot pedal, the needle works fine, but as soon as I step on the power, it jams.
I've taken the shuttle pieces apart and reinserted them about ten times. Each time, I think it will work, but it jams every time. Is this a timing problem?
I had the same problem with cleaning and jamming and this might sound silly, but when you're in the middle of trying to fix it remember to look up see that it is threaded up top. I did everything the pp's suggested and when they didn't work I realized the top thread wasn't still threaded around the tension thing anymore. After rethreading it, it worked fine. But I DID reduce the amount of thread on the bobbin at the same time as Drazil suggested.

Is your bobbin too full? Sometimes I have to take thread off my bobbin because of jamming problems. Sounds crazy but it has worked for me.
