Hiya, Jim --
Tnx for your thoughtful comments in reply to KC0ERG's email enumerating
the potential problems with N5OT's tower installation.
The thing is that while OSHA rules are promulgated to promote a safe
workplace where people are getting paid to perform some sort of tasks, in this
case tower work. OSHA rules do NOT apply to anyone else, that is, anyone doing
it on their own for free. You know - amateurs!
Yes, fall arrest harnesses are a pretty good idea and I sell lots of
them to hams but if you want to climb with a clothesline wrapped around your
waist, it's (potentially) your funeral.
Mark's method of attaching the other guys to the tower via a big metal
plate spreads the stresses across 2 faces and since the guys come in from
opposite directions, the net horizontal force on the plate should be
relatively
small since the forces most likely cancel each other out. If he had attached
only one set of guys directly to a leg, I would've had a BIG problem with
that. The way he did seems to work. Actually it's a clever solution. I've seen
ground guy points that had guys from several towers attached to it but they
were typical heavy metal (pieces of railroad track) that didn't have any
problem
with the forces.
Cheers,
