1. [TowerTalk] how much rust is too much? (score: 1)
Author: Matthew Kaufman <matthew@matthew.at>

I've just acquired a property with a 150 foot tower, appears to be Rohn 45, guyed at 5 levels. It was installed in the early 1970s(!). Prior to climbing the tower, I want to be sure it is safe. I've

What is the center to center distance of the legs? It could be Rohn 25 - not model 45 from the photos. If my notes are right, I measured it at about 17 inches, and the joints are like Rohn 45 joints,

Hhmmm ... going only by the photo, I can't believe that there's enough good steel left there to properly support that tower. The rust is bad enough to be crusty and flaking off, and if half the steel

Gotta figure out a way to measure that... maybe find someone with an ultrasonic thickness meter? The guy anchor looks OK as well, but I would inspect it right where it goes into the concrete. Look fo

Easy way to paint is with a sheepskin covered mitt. Just dig in the bucket and wipe away ... With this technique, how many sections of Rohn 55 will a gallon cover? Matthew Kaufman ___________________

If safety is your first priority, then you would know that it is much safer to perform work on a tower with both hands available. Get a proper positioning harness and a secondary fall arrest attached

I'm not sure I see a good reason for RoHS solder on connectors, particularly for hand assembly. Plus for this application, you'd be RoHS-exempt (7b) anyway. The low-temperature melt and quick transit

OSHA requires 100% tie-in to structure. Can't meet that with a belay technique. Of course if you are a fire department doing a rescue and not an antenna installer, different rules apply. Matthew Kauf
