Thread catches around bobbin race

I have a Sears Kenmore sewing machine and the thread keeps getting caught around the outside of the bobbin raceway after two times up and down with the needle. Then it is completely seized and will not sew. I can't find any visible thread. Any suggestions? Should I remove the shuttle and race and look under it? Thanks!!

Sorry for the late response!

Yes, do take out race ring and shuttle hook (refer to your users manual for the proper way to remove these) and use a paint brush (water paint kind, cheap ones kids use), lint brush (I use a 'duster' brush from the auto parts store for cleaning crevices in the dash - looks kind of like a stencil brush, but not flat at the tip) or compressed air to clean out in that area. It may not be a thread, but dirt stuck in there. It could also be a tip of a needle or pin.

While its apart also check to make sure there are no burrs on the outside edges while you have the pieces out. A broken sewing needle or pin can get down in there and burr it enough to cause the thread to catch. Clean the race ring, shuttle hook and bobbin case (if you have one on your machine - one of mine has one, the other doesn't since it has a drop in bobbin).

If there is a small rough spot or two, you can use the least coarse side of a foam emery board to smooth it out. Make sure it isn't a foam board for artificial nails or it will be too rough and cause more snagging. If there are many burrs or there is a gouge in it, then replacing it is your only option.

Wink Thread catching round bobbin race.

You have been given some very good advice by Kay. I woould also suggest you give the machine a light oiling while you have it apart.

Good luck

Also too.....make sure your needle is in the holding slot all the way.....also check to see if your tention on your bobbin thread is correct(it should be able to pull through with only the slightest tention to it.If after all this and you still have a problem........your timing might be slightly off.........this will probably take a service call.....good luck......Craftyboi
