Any way to separate Rohn tower sections that have gone through galvanic corrosion and rust in the connections?
I have a short tower made up of three sections that was used primarily for an OTA TV antenna over the past 25 years. Our neighborhood trees have long since grown too tall to allow OTA digital signals to reach the antenna so I have gone to a streaming service for television. I would like to take the tower down and either offer it to someone if they can reuse it or, barring that, send it to a recycler.
Unfortunately, the three sections of the tower (2 straight and a tripod) have fused together and the homemade steel base that was given to me when I acquired the tower sections has rusted inside the lowest section. I've tried pouring oil into the tower legs and then hammering it and that has not yielded any results. Would heating the joints improve my results? Am I going to have to just cut the tower apart and send it to scrap?
