[TowerTalk] Thrust Bearing adjustment

[Jon Pearl - W4ABC]

Funny... I just had this very same conversation concerning loaded masts 
on folded over towers with Mike, VE3YF.

Rather than using a completely empty rotor plate just above the rotor, 
I'm going to bolt a square piece of UV resistant UHMW (Tivar) with a 
center hole slightly larger than the outside diameter of my 2" DOM mast, 
in the space where a bearing would normally be utilized.
