when I borrowed a transit to plumb my Rohn SSV tower, I  was surprised to 
see
that it was a lot like spaghetti.  The sections  leaned in all directions. I
ended up just aligning the very top of the  tower.  If one could get rid of
the wind, a plumb line from the top to  the bottom would be my preferred
method if one didn't have a  transit. 


        This is common. It mostly  happens when tower sections are 
assembled laying on the ground so the individual  tower sections aren't totally 
plumb when they're stacked. 
 
        Is it a problem? Not  really. Industry specs allow self-supporters 
to be out of plumb 6" per 100 feet,  which is a lot less than the guyed 
tower spec, which I think is 3".
