Thanks Dan, I will check it out, but if it is as simple as the bobbin itself I'll try the local place first. Shipping time delay is killing me. I hope it is as simple as this. I am guessing that the tension spring I ordered if not the metal band itself, but a pigtail spring underneath somewhere or similar? I just got the # of it off the manual and it did not look like the band spring on the bobbin case.

I really do enjoy sewing and the end rewards, BUT we are gearing up for another line work (20 dressers) and have to put away soon to ward off all the sawdust.

The part you're looking for is called a bobbin case tension spring. If that's what you ordered, you'll get the right thing. There is no other spring in the whole hook-bobbin case assembly.

I still think there is a simpler reason for your problem. There is no logical reason why one minute you're sewing fine and the next minute you have no tension. Are you seating the thread properly between the tension discs on the tension assembly?

Awesome day! OK, so the spring I ordered was the one behind the bobbin latch, oh well, a cheap mistake. Actually, there was a little wad of oiley lint that my air gun did not get out, so the little screw couldn't tighten down and the thread just slipped out.
If I were doing this for a living (like I used to) I would look into the preloaded bobbins, but for now, we'll see where this takes me. I am enjoying doing this camper, though.
Thanks for your concern, help and timely reponse. I'll post my finished project.
