Jeremy, Jeff, etc,

	The paper does indeed make it sound like you can't tune it, but 
my info came from a Gleason engineer.  The bearing friction seemed 
to make sense too.  We never did change it becasue it worked better 
than the rest of the car, and certainly better than any of our 
drivers.  I think I would play with it though if I had another chance.
	Further, Gleason can change the torque BIAS alot by changing the
pitch of the threads on the spiral gears.  That changes the one-way aspect
of the gear train substantially. 

	But, alas, that is not something just anyone can do without 
tremendous machining capabilities.  :-0
