   I don't know if this will help but I'd band the edges with the solid maple you mentioned. MLCS.com has bits that will allow you to insert edge bands of any type of wood into, not on, the edge of plywood. Heck, you could use a different wood for effect.

   Thanks for the response. I was unsure how strong banding would be. I have scoured the MLCS catalog a few times and noticed that they have bits that will basically let you create a channel or groove for solid material. I'll look into that. Thanks

   Adding a solid maple edge around plywood won't help to keep it flat. It can warp pretty easily itself.

   Putting a couple of substantial batten on the inside of the door would help a lot more, as far as the panel cupping or bending, but the door would still be able to twist. Keeping a 20 inch by 6 foot piece of plywood flat over time is going to be hard. That's a substantial piece of wood. I would think about making it into 2 doors. And I would prefer to do it as 2 frame and panel doors rather than one solid door.

   A 2 x 6' door of 3/4 ply will be heavy; MDF core much heavier. Think about the weight racking the carcase. How about 1/4" ply with the maple frame?

   sean111, their is a plywood available called appleply. This is a hardwood plywood and is considered the most stable. But I think for your purpose you would still need to back it up with some kind of frame work to stop the twist and or cupping. This product is available 1/4 to 1 1/2 thick, generally stocked in maple veneer.

   You can make the door as a torsion box. Use 1/4" maple ply for the face side and any other species (or the same) for the back. Cut 1/4" thick strips of most any wood (use plywood cut-offs if you like) for the interior grid. The resulting door will be about 3/4" thick and will be stable, rigid, and relitively light.

   Fantastic comments all. Thank you all very much. I suspected that at 3/4 ply, the door would be too heavy. I like the idea of the torsion box because it ll still look uniform on the inside. Someone also suggested that i make an upper and lower door type thing. MDF core with maple veneer. I appreciate all the comments and thankful that i haven't made a big boo-boo yet. I'd make a frame and panel door but all the other doors in the kitchen are slabs. Hoping to keep the appearances uniform
