Hello all,
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.
