I had done it already to my newest machine on Monday. I bought a Singer 221K knowing that I'd have to work with the bobbin area. The finger was to the left of where it was supposed to be and just swinging back and forth. I took the little screw out and couldn't figure out how to get the parts apart or how to get it fixed until I went on line and found a picture of just what to do to fix it. In the mean time, I used a pair of tweezers to get out all of the thread that was under the parts there in the area. Got it all fixed and even had to adjust the tension on the presser foot to get it to hold the fabric. That was the first time I ever had to adjust the pf tension. Not like fixing and rehabing a 'boat anchor' but a start!
Great tutorial, Miriam. You need to do one on some of the other types of machines too.
