On the booms, I had 62 ft booms for my Razors, they were tapered, starting in the middle with, if I remember correctly, 3.5" dia and 1/4 wall and tapering down, telescoping towards the ends. I had only one guy using philistran. Mounting plate was attached to the center piece with small mast to support the guy. Then the whole thing was lifted and mounted on the Bertha.

Cheapest source of variety of aluminum tubing are the old antennas and junk yards. Otherwise new stuff, telescoping I bought from Texas Towers.
