Bottom of barn doors are rusting out. Need to remove doors to effect repairs but don't know how best to go about it. The hinge pins have been painted over and are not responding to paint scraping and hammering. And I'm hesitant to remove the six threaded bolts that connect the door to the hinges for fear of alignment problems upon reinstallation. I've fabricated an "easel" of sorts (from a step ladder) which will hold the door in proper position, but I'm very unsure how best to remove the door........hinge pins, or bolts. I'm not afraid to get aggressive with the hinge pins if that is the way to go. I just want to make sure I'm not overlooking something. Appreciate any and all help. Thanks.
