I have lowered the big vertical. I have a few shots of it coming down. It
can be viewed at <http://www.geocities.com/lm2000us/chinagulch.html>
Look at the bottom of the links for the 3850 group.
Here is a example of taking down a large tower with a gin pole.
A couple of observations after 15+ years of service. I used "X" aircraft
cable on the sides for stiffening. While the cable survived well in general
terms, several of the X points where the cables get close together, showed
signs of wear due to contact during high winds. I suspect it would have
been better to have a fixed spacer or to tie them together. The "NOLOX" I
used to coat the joining of the aluminum tubing worked great even after 15+
years. The parts pulled apart with only initial resistance. The 1/4"
dacron rope that I used for insurance during storms showed no signs of
aging. The three of them were used as the strong back cable that goes from
the 88 foot level to the gin pole in the picture. The dacron did have
evidence of moss growing on it?
It is still for sale.
