Issue with shaft/gear linkages

Bill:
It appears top be related to the pinions. The crash can be stopped by deleting the bottom right bevel, but all the pinions seem to be creating the
rotational instability. Have a few web issues to deal with, but Ill look into it shortly.

Bill:

Problem seems related to fusing. The shafts on the objects are not in place properly, you'll find them almost impossible to select.
So when run is pressed, they move quickly to position causing weird forces all over., Im trying to reproduce an dIll see where that leads.
