I would have no problem trying my loosey-goosey welding skills on refilling the egg-shaped hinge pin holes for the front doors, and then drilling out fresh ones. The biggest problem I see with it is trying to determine where the original hole centers were (and new ones should be). Won't help to have new perfectly sized holes if they're a 1/16" off in different direction. I've searched off and on for months to see if there's some kind of printable template I could lay on top of the hinges to mark the new hole centers, but can't find anything.

Does anyone know how everyone else does it? Have you done it? Any tips or advice would be welcome.

 

Did you try making a copy of the opposite hinge with cardboard?
