Dave:

From that description, I suspect you are going to find all the bolt holes in
the tubing elongated from torque. We usually drill slightly oversize holes
for our fasteners, but in this high stress application, the holes should
start undersize so the fasteners have to be driven in and are tight from the
get-go. Also, it is necessary to select fasteners which do not have threads
where they pass through the walls of the tubes. This is often the most
difficult challenge.

It could be the masting, tho. I have a 3: diameter piece that goes into
the
rotator and is "pinned" there by a bolt, as well as clamped, then it goes
to a
"jackshaft" that is a smaller, about 4' length of 1 3/4" stainless steel
with 1
or 2 1/4" bolts thru it. That goes thru the 1 3/4" top section collar,
then a
3" heavy aluminum mast slips over the stainless jackshaft and is secured
with 2
quarter-inch bolts. There's probably some play in the bolts, but I don't
think
there's that much. Mounting bolts on the bottom of the rotator - I think
those
may be loose.

Thanks for the info.
