Rethinking what Steve has just posted, yah you bet some outside rings
and mast/rotor centering is solved big time in a very positive way solid
way. I'm all in now mm

I would plan on mounting the rotator and mast outside of the pole,
rather than inside.
I'd install a couple of "ring collars" - off the shelf weldments used
in the cell business - one at the pole top, and one down 6' or so. To
that you clamp a 4" or 5" pipe mount, which can be plumbed with no
trouble.
Then to this pipe you can attach shelves at any height - one for the
rotator, and a couple for thrust bearings for example. You can make
this as heavy duty as you want, mostly with off the shelf parts - just
a little ingenuity and fab work required.
BTW the ring collars come with three faces for clamping stuff, so you
could have some fixed yagis just below the tower top facing in
favorite directions.
Anyway, it gives you way better flexibility and serviceability than
having stuff inside the pole.

Yep, planning on a small crane. Not sure this type of flange is ideal
for a buried pier footing. I've not found specific details on those
beyond conceptual, though.
Also planning to fabricate a cross brace inside for rotator and also
for thrust bearing, and perhaps a fiberglass cover... Unless I can
find something field tested by others. Thanks for the reply.
