      Rohn specs allow 1.5 sq.ft. of 25G @ 70 MPH (20 psf wind force) for a
height of free-standing 40 feet. The inference is that at little or no wind
the tower has MORE than adequate ability to hold a climber or two during
construction at that height.

      Yes, there is some 'pucker factor' involved. It's like climbing a mast -
it's the ability to do these tasks that separate the 'professionals' from the
'amateurs'. 

     Not very many people are comfortable doing these kinds of tasks. Climbing
and working on a tower is 90% mental. If you're psyched out and uncomfortable
- that's fine, you know where your limit is. 

       This isn't too confuse professional capability with 'crazy', though.
I've heard of non-professionals doing some pretty crazy stuff that NO
professionnal would touch. 

       BTW, I "have safety belt - will travel" if anyone is looking for
someone to do professional tower work. I've worked on over 125 amateur
stations and many commercial sites.
