[TowerTalk] raising Rohn 20

[Fred Roberts]

When I had to run a rope over the peak of the roof between the tower and a friend's 
tow truck winch, I made a 2"x4" x-frame and mounted a steel wheel (looks like it came 
from a generator).  Running the rope over the pulley worked just fine - the tower 
weighed 900 pounds (88' crank-up).

So a steel pulley from the auto junk yard worked fine.
