[TowerTalk] Mast alignment was:refurbish a Thrust bearing?

[RICHARD L OWENS]

So, how about locating the open side of the rotor bell such that the
set-bolt is opposite, and loosening the u-bolts a bit at a time while
tightening the set bolt till the set bolt has the mast clamped solidly? 
Seems that would avoid any centering problem.
