With small verticality errors, straightness is more important than
vertical perfection.
Keeping the tower "in-column" is more important than a little lean.

Doug,
In my opinion you should not lose an sleep over this project. If you were able
to suspend yourself in mid air, you could probably put a slight amount of
pressure with one hand (perhaps two fingers) and make it plumb. If it will
make you feel better leave that plumb bob on it and when you tension the guy
wires make sure it's perfect.
I have 13 towers up right now and have never in my life used a plumb bob on a
tower. They look pretty straight up and down to me :-)

OK,
I am using a plumb bob...First test attaching a plumb bob at 20 ft level (top
of 2nd tower section)...I see about 5/8 inch of deviation from Sight A and 1
1/2 inch deviation from Sight B

Subject: Re: [TowerTalk] My first tower section is not plumb...
Drop a string with weight (plumb bob) from leg at 20 ft point. How far is
string from leg at concrete base? Do it with no wind.

Hi,
I have a problem...i discovered my first tower section is not plumb...something
happen after concrete cures. Remember i have 3 ft buried in concrete and 7 ft
above concrete (1st section).
I add the 2nd section and i am planning install the 3rd section with the
permanent guy wires.
What to do to correct the plumbing ??
Thoughts?
