Bill,
Thank you so much for your deep insights and very interesting links. At first
glance, it looks like there are tons of incredible things there. I will
definitely explore them further when time permits.

I agree with all your points, which doesn't happen very often.

I'm not sure if free hobbing could ever work, but what about using two
sprockets, a chain, and a tensioner?

I'll get in touch about that industrial EM simulation idea, and I'm eager to
see what comes of it.

Ever so,
Igor
