I don't think the hinges are going to be the weak spot. 3 should be
fine. Be sure you use hefty screws and be sure you know how the door
carries the stresses..

Can you elaborate on this point? My plan is to use other doors in the house
as a model, with the outer hinges a few inches in from the top and bottom
and the center hinge equidistant between them.

Thanks.
