Basically you have to force the mast to yield in the opposite direction of the bend. Do not underestimate the force that will be required. It takes a lot to kink a H16 mast. You will get quite a bow in the opposite direction before the aluminum will yield.

You could try using a hydraulic jack. Support the mast at the ends of the bend. Jack at the middle of the bend. Spread the load by using a 2x4 between the jack and the mast. Give it a good bow then back it off and check your progress. Repeat as neccessary.

Also, if you post on the Open forum you may get better response. Bent masts are a generic problem.
