Good idea, Jonathan.

@Indianwoodchipper – If look at a bookshelf, there’s normally a face board attached to the shelve edge. The principle is to prevent the shelf from bowing under weight of the books. For tables, the apron serves the same purpose. Jonathan is advocating the same type of thing, and it adds a functional element at the same time. The maple is a heavy, stiff wood that would help bind the door in place once you have the ash straightened. The only real question is whether or not it will be enough to hold it? I would suggest that the maple needs a bit more mass than Jonathan has drawn, but the principle is solid. You could even figure a way to sandwich such a board to a piece of metal plate between the maple and the existing door. Or, for that matter, just use the plate itself.
