Steve, no question...any amount of bolt height reduction does get me closer
to the right distances...and that will make the base section easier to
install. It's certainly one solution to consider, and perhaps one part of
the final solution.
Prior to this message thread, some folks have suggested that since there's
1/8" wiggle room, the tower base may just fit anyway. All 140 Ft. of tower
is bolted together on the ground. A 200 Ft. crane then hoists the entire
tower onto the base. The tower legs are *solid* steel, not hollowed out.
This adds a significant amount of weight to the tower and that weight can be
leveraged to conform the bolts -- that's IF it's close enough. The J-bolts
are so strong that if even a tiny fraction of an inch of the bolt top lays
onto the foot, it ain't going on, even with all that weight.
