I used to repair aluminum street light poles. A car would knock them down and the base would be cracked, and when the 30-40 pole smacked into the ground it would often bend. I would straighten them and weld up the cracked bases, and put them back up. You would not believe how far I would have to overbend them in the reverse direction to straighten them! I'd tie one end down with a truck, the other with a forklift, and pull up in the middle of the bend with our crane. So unless something crashes into your mast, it really is unlikely it will get bent sitting on saw horses.
