A bit more friction than is ideal, but it'll work.

The VP output shaft actually doesn't quite reach far enough for that.

I can run it through some tests tomorrow but I guess I'm still a little skeptical that this issue would only crop up now, after our other changes. How much deflection in the end of the shaft are you expecting? All the mounts for the motor are still as solid as ever.
