[TowerTalk] Thrust Bearing Installation

[john at kk9a.com]

Great answer Scott. I would just like to add with some rotators such  
as a K7NV Prop Pitch, it is recommended to have the full weight on the  
rotator.

Probably one or the other, not both. That's "overconstrained", which
means anything just slightly out of true can produce very large forces.
The easiest way is usually to let the rotator take the vertical load,
assuming it is within its rating.
