[TowerTalk] Mast install help

[gc]

Steve makes a good point.  The gin pole I use is 2in OD with a 1/2in wall
6106 aluminum.  The bracket for the tower was made locally and larger than
a Rohn model - the pulley is also rated for 600lb.  Many great suggestions
and I have a couple to try.  I hope that this may help others in the future
when they find themselves in a similar situation.
