     Well, it's pretty common. Assuming that they were manufactured
corrrectly, then shipping damage is the problem. Unless it's bad enough to
submit a damage claim, it's easy enough to remedy.

     BTW, the other new tower sections problem is excess galvanizing slag in
the bolt holes. Use your taper punch/alignment tool/drift pin to clear the
excess. Also check inside the leg couplers for ridges of excess slag. Use a
rattail or other round file to take that stuff off. The slag will jam the leg
as you try to seat it.

     Usually.

   For the most part, no.

    Using a turnbuckle or comealong or another method is a time honored
tradition.

    One of the 10 Most Common Tower Building Mistakes (a free copy is
available  from TOWER TECH) is NOT fitting the sections on the ground. It's
much easier to find a potential fit problem and fix it on the ground than it
is up on the tower. Don't assume that the sections all fit together. Use a
pipe or pry bar to bend the wayward legs into the correct alignment. Your
tower erection will go much smoother than screwing around with it up on the
tower. I recently installed 100 feet of new 45G and about half of the
sections needed persuading. 

    Put a dollop of anti-oxidant inside the leg couplers. They'll not only
slide together more smoothly but it'll retard any corrosion formation. Plus
if you want to shunt feed the tower, it'll provide a nice solid electrical
joint. 

    If the sections fit but won't slide down, use a comealong to pull it into
place. Yes, taking the sections apart in the future will be "interesting" but
maybe you won't have to do it - hi!
