I used to have a tree in my front yard that had the perfect fork in it for doing these jobs. I performed metalurgical deformation on many items. Everything from straightening pool skimmer poles to making a fender for a trailer to fixing a severely crunched running board. A storm took out my natural mandrel last summer.
Of course to do that with the door, you'd definitely need a helper.
