I am in the process of putting in two new towers on my property (yes, I am blessed). I'm a little nervous about Cadwelding to the legs. I suppose you'll all tell me it has been done dozens of times,

Larry, can you connect some tinned copper lugs to the lower set of three (or six) leg bolts using the existing bolts? For added security, you could add six locking nuts. The ground wires would then c
That may be a nice alternative, but what advantage does it offer over simply connecting a regular ground clamp? It seems like a very nice idea, but I need to understand what I gain versus just clampi

You need not be concerned with the ground clamp loosening or damaging the galvanized finish on the tower leg. A regular ground clamp is likely just fine. I only mentioned it as an alternative to cadw
Copper direct to a galvanized surface isn't best practice... you need an "isolation" metal like bronze or stainless steel between them. Cadweld serves that purpose and gives you a mechanically solid
I got a private note indicating some real-world problems (holes in the pipe) when Cadwelding Rohn towers on at least some occassions. So, for the record, it doesn't look like a great idea to Cadweld.
I would never exothermic weld anything to a relatively thin wall tower leg. No way. Especially when you've never tried it before and have no skills in doing such! I've got a cast zinc clamp on my sit

I just use a large, solid "bolt on" terminal for the proper size wire on each leg and lots of noalox. As it's stranded #2 I have just splayed (fanned) the 7 strands out to close parallel and clamped
Cadwelding to Rohn towers ... it doesn't look like a great idea Great idea? I can't imagine anything more stupid. Taking an uncontrollable high heat source to a tower leg? Why not use a saw? Ken K5RG

Nervous would not cover my initial reaction... After having blown quarter sized holes in heavy chain link fence posts, I wouldn't even consider it. Not to mention that you have destroyed the galvaniz

In a previous life I was a certified R/D and production welder. Letting something so uncontrolled as cadweld loose on a relatively thin steel tube like a Rohn leg is just begging for trouble. Yes, th
