I'm trying to re-use a Rohn hinged base that is damaged but still quite
solid. The holes were elongated.
The 25G tubes on the base are 1.25" OD nominal. I found some Aluminum
6061-T6 to be exact, that has a 1.25" ID with a 0.200" wall thickness. It's
anodized and some pretty beefy stuff.
I have three concerns:
1) Strength of a sleeve of this aluminum slipped over the tubes between the
base and the first section of 25G. Will this aluminum be able to take the
stresses of a 40' guyed tower with a tribander, mast, rotator, etc?
2) Electrolysis. I know a little less than nothing about electrolysis
between a galvanized steel tube and an anodized 6061-T6 aluminum tube. Is
this asking for trouble?
3) The fit is so tight, I'll have to pound the sleeve onto the first section
and then onto the base. I doubt that the galvanizing will survive. In
addition, I may be forced to lightly sand the zinc smooth just to make it
fit. Once again, is this asking for trouble?
Thanks for the help.
