Well I think the way I proposed to do it is the easiest and most
accurate way to do it. Driving the leadscrew direct for best
accuracy, and a simple right angle bracket to hold the motor.
My 4" Makita grinder with cutting disc should make easy work of
cutting a rectangular slot in the knee for the belt.
I'll have to post pictures when finished.
