Hi Billy....I have a question for you regarding my 1940 Singer 201-2 bobbin case. I have been cleaning my machine and finally took the bobbin case apart. I watched very carefully to get everything back the same way. But I can't get the the ring over the bobbin case to lay flat. When I turn the wheel by hand toward me, it is hitting something under the feed dogs. I have checked my instruction book over and over and tried different things and it still hangs up. I even had DH try and help. No luck. I appreciate your help. This thread is amazing. Thanks, Nancy O.
