How do you propose to lock the ratio at 1 to 2, John. I mean, 
physically, what are the details of that?

The reason I ask is that if you take a bicycle wheel and hold it up at 
one end of the axle, you'll see both the spinning and the precession. 
The other thing you'll notice is that the faster the bicycle wheel 
spins, the slower it will precess. And unless you've got a bright idea 
otherwise, you're going to find that you won't be able to change that 
behavior, so that locked 1 to 2 ratio is going to be a problem.
