[TowerTalk] Guyed + self supporting /2 ??

[Patrick Greenlee]

Right, John, so out of consideration for the wisdom of your comments and 
oodles of folks saying NEVER guy a free standing tower, I only guyed the 
bottom section.

Somehow I'm reminded of Woody Allen's comment, "How about if I quit when I 
get near sighted?"

Anyway guying the bottom section doesn't add tension to the cables and 
pulleys, just some compression to the legs of the bottom section.  I put 
only a little tension on the guys.

It is the weaker legs near the top that are the problem,
the severity of which depends on how much the tower tapers.
