[TowerTalk] Crank up tower bracing rubbing against cable

[K0DAN]

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.

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.
