big cabinet door sag - prevention

I am finishing a double door tool cabinet/pegboard. Each door is made of
hickory frame with 3/4 plywood panel, roughly 3" deep. Overall dimensions
for each door is 33" x 26" x 3" - so they weight a bit. These doors sit on
top of the pegboard cabinet, also framed in 3/4" hickory, with vertical
pieces in the center for adjustable shelving.

I am using piano hinges the entire height on each door, but still think
gravity will eventually pull the doors out of alighment. Thought about using
a latch on the top, or something like a pull through latch made for table
leaves.

Any suggestions/experience?

If you use a good quality continuous hinge and one as large as you can
live with, I don't think you will get any sag from the hinge.

Good joinery will help, too. Tom

If the backs are let into the sides w/ good precision, they really
can't go anywhere themselves so the only place for movement is the side
frames or the hinges. A _good_, heavy piano hinge will support a lot
of weight, the specifics for any given choice should be available for
it. So, it seems to me the question boils down to making the
supporting frame sufficiently stout or reducing load.

One way to do the latter would be to use center stile and double doors,
but that may not be suitable depending on actual use envisioned.
Another possibility is I would wonder if the 3/4" backing is actually
needed but whether 5/8", 1/2" or even 3/8" would be sufficiently stiff.

With a plywood panel you could glue it in and gain some more racking
resistance.

thanks for the replies..I am using box joints all the way around. rails and
stiles are 3/4" hickory, with the 3/4" plywood face panel sitting in 3/8'
dado (free floating), even with top so one solid surface..will stick with
existing piano hinge and see if it holds..thanks all
