Is it really so hard to get the thrust bearing in alignment with the
When I put up my tower with a pointy top, I did some ground work to
achieve alignment. I temporarily mounted the top section at ground
level. Then I placed the mast in the top section, then the rotator the
end of the mast, then the attached the rotator shelf to the rotator,
then the shelf to the tower.
In this way, the shelf is aligned at the right angle so the rotator
axis is the same as the collar.
Result - no binding.
