I am building an armoire from quartersawn white oak. It is a large piece and is solid QSWO. My problem, and my question has to do with the single door. It is a large piece, 29" X 56" rail and style construction with two panels. The rail and stiles are all 1" thick and the panels are 3/4" thick, setback 1/4" from the front, the stiles are both 6" wide and the top and bottom rail are 6" wide, with the center rail 5" wide.
To make up the panels, I bought a large piece of 8/4", 10" wide by 50" long. I resawed the piece into two 3/4" halves. I then bookmatched the halves forming a large panel which I crosscut into the two panels that I would need. I then sized both panels and left them for a week. From fear of warpage, I clamped them flat on my bench. You guessed it, they both warped. The panels are 18" wide. If I hold one edge on the bench, there is a 3/4" gap under the opposite edge. Since they are to actual size, I can't cut them and reglue.
I have to cut a rabbet around all four panel edges, each 3/8" thick and wide. They will fit into a 3/8" dado which is set back 1/4" from the front of the stiles and rails.
Now to my question: Am I inviting trouble if I force the panels flat into the dadoes cut into the stiles? I will have only 1/4" of material on each side of the tongue.
