Be sure you check the integrity of the tower
itself AND the guy anchors/guys.
Amen to that. One of the local guys was seriously hurt when a tower he
was taking down fell with him on it. One of the turnbuckles parted.
The widow said the husband used only stainless steel hardware. This
turned out to not be true.
And keep in mind that towers made with tubing rot from the inside out.
You can't check the outside and know if the tower is in decent shape.
A local ham, as well as business-band tower owner, looked up at his
tower one day and saw that one leg was bowing out. This was tubular
tower as in the Rohn 45 or 55 stuff. He replaced it with a tower made
from solid rod. There is no 'inside' to rot with solid rod.
Since one cannot see the inside of a tower leg, and since tubing rots
from the inside out, it is good to be cautious.
If I were going to climb an old tower I would guy it securely every
10' on the way up. I dunno that that would prevent it from collapsing,
but it would go a long ways toward preventing that. Old tower is
dangerous stuff.

Called the "Yellow Jack".
That said, be EXTREMELY careful disassembling an old tower,
particularly one that you may not know much of its history or if it
was installed properly. Be sure you check the integrity of the tower
itself AND the guy anchors/guys. The safest way to take it down may
be with a crane. If you can..a sawzall/torch may be a better solution.
Be safe and understand what you're doing. I would check the Towertalk
archives on this subject.

I remember seeing that tool in magazine ads. I have a modified
light weight
scissor jack to loosen tower sections. It loosens all three legs at
the
same time. It works very well. If you don't find the rohn tool you
might
consider the jack.

Subject: [Elecraft] OT tower disassemble tool
I have to take down a 60ft Rohn-25 tower that's been up for 20 plus
years. I remember seeing a tool advertised in QST and CQ for just this
purpose. It resembled a long "lever" that was dimensioned for Rohn-25
specifically and helped to pry the sections apart. Any leads to this
"tool" would be greatly appreciated. Thanks in advance.
