Thanks Joe for this link. It really is filled with tons of information. I was saddened to read the part where all of those bobbin cases were stolen at that class. I do plan on telling all of my friends about that recommendation.
I would like to thank you for all of your knowledge that you share with everyone on this board.

The 50 bobbin hook assembly won't work right with the 51 case if I understood what I read correctly.
I'm not an X-spurt on this but I recently rebuilt a bobbin case and it's hook assembly rather than drop the big bucks for a repro replacement assembly. The bobbin case part number ended in 50 and the hook assembly parts are a wee bit different from the hook assembly for the case ending in 51.
