Another thought just hit me.  Perhaps it might be possible to straighten the
mast back upright with
less stress than previously talked about.

Tie a rope about 3-4 feet ABOVE the bend.

Make a pipe that will clamp to the bent mast AT THE BEND and go out
to the mast, at the knee of the bend. This should be about 2-3 fee long.
This could be done by cutting a hole in the pipe about 1/2 inch from the
bottom and feed a flat bar through the hole.  Put a pipe clamp around the
mast and clamp it the flat bar.

Loop the rope OVER the end of the pipe that was added and send it down the
side of the tower.

Now pull DOWN on the rope, not outward.  And you don't have to be on the top
of the tower to do it.

Just a thought...
