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
aprx a 4 inch overlap.  Bottom section was aprx  29 inch C to C on the
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
Trylon  free standing towers will do this...and esp if you weigh 200 lbs.
legs are sorta quasi U shaped...with 2 bolts per leg, one above each other
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
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
when he climbed
mine back in the mid 70s....  swore it needed guys...they dont at the 55
   Some sections will develop surface rust..and most dont.
