What about something like Slipp-Nott (not the sports mat!)? I think it
is being sold by Tennadyne. Not sure but it may only fit a 2 in mast
which wouldn't help you of course.

I have 2 large Yagis attached to a 3 inch OD ¼ inch wall thickness Chromoly
mast running down the tower to a ProSisTel PST-71D. On a windy day, I hear
creaking sounds from the tower. The mast is slipping slightly in the rotator
mast bracket. I’ve already tried to tighten the 6 bolts, but it still slips.
I don’t want to tighten them to the point where they might snap. I’m
thinking that what I need to do is to go up the tower, drill a hole through
the mast (the rotator mast bracket already has holes), and pin the mast and
bracket. I understand that it’s not easy drilling through Chromoly pipe, so
before I try this, I thought I would ask if any of you have any other
suggestions.
