[TowerTalk] Fwd: How to fix crooked Rohn 45G short base?

[Hans Hammarquist]

Hi Blake,

That would give you an about 4 inch lean at the top. I wouldn't worry about that unless you are approaching a limit how much your structure can carry, and that wouldn't be a good idea anyhow.

Just leave it alone. If anyone later will tell you that they noticed your tower is leaning and expressing concern about it. Just tell them that it has something to do with: Improved propagation, compensation for prevailing wind or something like that.

You'll be fine.

Hi hi,

I’m putting up my first tower, a 40’ free-standing Rohn 45G (45SR040). I had my landscapers' help in getting the short base buried and cemented in, and unfortunately we’ve ended up crooked. I bolted the first section on top of the base and we’re about an inch out from top to bottom of the first segment.

What are my options for fixing this? I’m aware that Rohn doesn’t like drilling the bolt holes, even to get out the excess galvanizing, so I don’t imagine hogging out some holes would be the right way. In the archives I saw passing mention of bending the tops of a short base, but I wasn’t sure of the context so I don’t know if that’s the right approach.

I’m hoping we don’t have to jackhammer the base out and re-pour, so I’d be grateful for any other recommendations. Thanks!
