My 60' Universal Aluminum tower used to move when I climbed it. It seemed
like a lot of movement but as Jim said it probably was not. I sort of got
use to the movement and never had an issue.

## It appears his tower is a 55 ft Delhi. They came in 8 ft
sections..with
aprx a 4 inch overlap. Bottom section was aprx 29 inch C to C on the
bolts.
Aprx 16-18 inch wide at the top. Cross pieces are Xs...and all riveted.
Thats normal for it to start the wobble at the 45 ft level. Even the
bigger
Trylon free standing towers will do this...and esp if you weigh 200 lbs.
The
legs are sorta quasi U shaped...with 2 bolts per leg, one above each other
on
the upper sections...and 3 per leg on the lower sections.
Seen from the ground by a 2nd person, 2nd person wont see it budge. But
the
fellow on the tower will swear its moving a bunch. They all do that...
unless guyed. A buddy of mine who had guyed rohn-25 at the time, freaked
out
when he climbed
mine back in the mid 70s.... swore it needed guys...they dont at the 55
level.
Some sections will develop surface rust..and most dont.
