Hi Ken:
Thanks very much for the tip. It took only a gentle push after I opened the needle plate to find a spot to apply force with a screw drirver. I got bobbins out from both machines!
The 2nd machine is running back to normal. However, my first machine (Union Special 63400B) has more trouble because I had tried to remove the bobbin case from the shuttle hook. When it didn't work, I put the screw back but now I know I lost the right position/timing at then. Do you know where I can find the diagram to show me the right position of various parts with correct timing? I knew that the timing requires higher level technique to fix it and I am willing to try... I am already very grateful to you for getting one machine back to life! thanks again.
