The little peg is on the bobbin winder. It engages the notch on the inner edge of the bobbins shaft to spin it. They can wear or get broken.

I have a question about the class 15 bobbin cases for the zig zag machines.
There are 2 different part numbers for them, one for the side loading machines and one for the front loading, but I can't see a difference in the cases at all... of course the price is different on the 2, which implies that there is some difference....
As for the bobbins - there are a couple of different qualities of bobbins. I have about 5 different choices in the spreadsheet for my supplier, all of course with different costs. MOST places, Hancocks, Joann and even a lot of the the LSM places will stock the cheaper quality because (they think) people won't pay for the "better" cost, especially when they apply their 200 - 500% markup.
The newer machines don't care as much about the quality control on the bobbins. I have never had trouble buying the higher quality ones, even in vintage machines. The part number for the metal 15 bobbins I ordered is: 2518-A. I haven't had to order class 66 bobbins from my supplier because i have 3 parts organizer drawers of them from other machines.

Tammi,
One of the differences in the class 15 bobbin cases is the position and length of the slot. The needle at its lowest has it's the tip in that slot. If you use a case made for a side load straight stitch machine in a zig zag machine the needle will hit the case.
The width of the zig zag is the other differences. Wider zig zag stitches need a wider slot in the bobbin case.

Thanks Cathy! How the heck did I miss that? So am I right then in thinking that a BCase made for the ZZ machines would be fine in the SS machines? (Provided of course everything else is the same - i.e. it has the finger at 1 o'clock, etc.) I must have been very lucky the couple of times I've had to order the case for a machine, or else I managed to order the right one each time. The ZZ machines I'd been thinking of that I thought were side load are ones that have the whole hook move side to side, so the slot could be SS sized, yes?
THe ZZ width must be why I have 3 different sized slots on the BCases here.
I knew about the tip of the needle. I learned that when trying to take a BC out when a machine was thread jammed with the needle in the down position.
Scissors, thread cutter and a lot of muttering to the rescue.

Tammi,
I usually buy from my supplier the 11mm wide width ZZ bobbin case. I think it is #JO1313Z. It's listed as high quality.
Yes, the side loaders don't need the wide slot.
