when I borrowed a transit to plumb my Rohn SSV tower, I was surprised to
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".
