These three pictures illustrate the bandsaw mechanism for stopping the saw at the end of a cut.
There is a large hex head bolt with jam nut which looks like it should hit something, but all
it hits is the wheel cover (removed in these pictures).  Consequently the on-off switch is what
stops the saw's downward descent.

After assembly, I have a piece left over.  Maybe it attaches somewhere so that the bolt hits it instead
of the wheel cover?
