I use Norm's NYW plan for the size of the box, but what I do is make it as 4 raised panel doors and join them together. Got the parts cut out a week ago and yesterday ran them by the shaper cutter. I leave my 3/4" bore cabinet set double mounted on the spare 1/2" shaft. And with a Wixey mounted on it, I can record the height settings in case I have to make a replacement piece. Today I will make the raised panels.
