Hiho,
I thought about that, but frankly, figured that was more of a hassle, and more expense than what I am thinking of. That said, I am still wondering what the right way to do this is. The idea is still more for fun than anything else. It is of dubious utility unless one has multiple tables to plinth and one only wants to use one motor at a time. It is a tinkerer's toy, not a music machine.
