I've been thinking about this project a lot, probably too much, but these kinds of projects seem to take on a life of their own and become obsessions. By now, I have a pretty good idea of how to make this all work (thanks again to Eric Peltzer's great documentation), however, the one thing that was still missing in my plan was ... how to mount the motor/ jackshaft assembly so it wouldn't fall off at the first bump I hit.
