Another improvised "leverage amplifier" is a large tire iron used to
mount/unmount truck tires. Years ago a contractor gave me one of these, it's
about 5' long made of really hard 3/4" steel. It does NOT bend, and has a
nice tapered lip on it for where it's supposed to pry the tire rubber on/off
the wheel rim. Works great as a big pry bar and I have used it on the tower
to make all the bolt holes line up when using the tilt-over feature. I never
thought about using it to correct bent side braces but I'll bet it work
super, and is also small/light enough to fit between nested tower sections.
Don't know where a person would buy one, but it might be possible to rent
one for a couple bucks from any tire repair shop that services tires for
semi's.

Subject: Re: [TowerTalk] Crank up tower bracing rubbing against cable
Thats what I did to tweak my two bent round bar braces braces back out on my
tower. I used a pry bar and slid a 10 foot length of 2" water
pipe over it for extra leverage. Didnt need to be that long but it was what
I had on hand. Just a little nudge at a
time and keep checking does the trick.

Jonathan, this sounds like a recipe for disaster! 300 to 500 pounds of
force is one matter; making sure you don't exceed that with a vehicle is
another matter. I have seen no 500 pound fuses.
Another consideration is if the tower can handle that much force. 500
pounds at the end of a 20ft lever (telescoped tower) is 10,000 ft
pounds/12000
inch pounds of over turning force!
A longer crow bar can be as simple as the existing crow bar with a length
of pipe slipped over the end.

Hi All,
Thank you the replies. I also received many replies in private. Many of
you suggested of bending the bracing with a crow bar or hitting it with a
piece of wood. Well, I tried both methods today and neither of them
worked.
I would need a really long crow bar to bend that thing. The wood method
didn't work as the wood absorbed all the pounding.
I have an idea that might work and save me a lot of time. My tower is
very close to my driveway. I could tie a cable to the bracing and attach
the
other end to a winch or a vehicle. With a 300-500lb force I should be
able
to bend the bracing just enough to clear the interference. When
retracted
the tower should be able to withstand the pulling force, I hope. Since I
don't have a winch I will have to ask my neighbors for help. I will
report
back on my progress and result. Thanks and 73.
Best Regards,
