OK, so you have more than 2000 pounds bearing on the tower base.  What is
the design limit on the base as poured according to Rohn?

The bottom three sections were "belled" into each other to the point it took
a jack to get them apart. 

This has been posted before.  How are these sections connected?  Seems to me
if it is Rohn 25 or above, or equivalent, each log would be bolted at two
points.  If so, how could they "belly" without breaking the bolts or
elongating the bolt holes?
