Vertical Mast

[Jay Pryor]

What's the best way to ensure a mast is vertical?  My plan is to use a
level and go around the mast, tweaking for the vertical position by
adjusting the thrust bearing.  The manual for the rotator talks about the
"eccentricity tolerance" but does not address how to minimize the
eccentricity. The manual for the thrust bearing is in Japanese! (?)

Thanks.
