REFLECTOR: Castoring washer on nosewheel

[Laurence Coen]

Brian,

You haven't lost your fiber washer, you never had one.  If memory serves, 
you got into this game about the same time I did and the fiber washer mod 
didn't exist at that time.  I use the nylon washer and it works very well. 
Something I found about my set-up that I think is worth checking is that the 
torque was not constant as the nose wheel is rotated to different positions. 
I set my torque with the wheel straight ahead.  My first high speed left 
turn produced a slight shimmy.  I found that when set for a left turn I had 
a couple of pounds less torque and set for a right turn an increase in 
torque.  Find the loosest position and set that to spec.
