Thank you for the replies so far, both on and off list. Scott knows the
person who owns the crane, so it can be had for fuel costs, I suspect.
I like the temporary guying ideas, and I feel that this would work to make
the tower safe to climb for rigging a crane lift or conventional
We are leaning toward a crane lift and laydown, since there will be little
cost for the crane and it will be safer. The base is a pier pin with a
single bolt. Since the joint bolts may have been overtightened during
installation, I expect difficulty in separating the tower sections. I do
have a tower jack.
If we take the tower down with a crane, the work of removing the rusty bolts
and separating the joints can be distributed among a larger ground crew than
having one or two climbers perform this work up the tower.
The best suggestion I heard for removing the rusty bolts is to carefully cut
off the heads with an abrasive disc and tap the bolts out with a punch.
Any more ideas are welcomed.
