So I enlarged this TV cabinet and I need to make cabinet doors that open to cover the TV. The opening is 72" x 49". I made two doors and I plan to rip them vertically to make a bifold setup that closes and slides into the cabinet on the geared hardware. I was going to use a piano hinge between the doors, but I really want to solidify the doors. They are poplar, edge glued. I am contemplating 1/4" plywood glued to the back of the panel (there is a recess on the back between the rails and stiles) and then even another sheet that I can glue and screw to the rails and stile. I'm afraid the panel movement might cause a mess. The individual panels will be less than 16", so not a lot of width. Priming the back before hand is a thought as well, to control humidity movement, am I over thinking this?
