I am building a small game board, around 8×8 inches by 3 inches. The Top is going to be a piece of crotch walnut and that is currently about 1/4 of an inch thick. If I need to take that down I can do that on a drum sander. I need to put some kind of frame around this but I am worried about wood movement. I had planned on doing about 3 layers of walnut for the core, but I am worried about wood movement. I would prefer to stay away from MDF/ply if possible. I also plan to have a small drawer, something like 2×2x1 for the pieces in the board. Any tips would be greatly appreciated.

Alternate the grain of the core, and use 5 plys instead of three. Plywood gets its stability from alternating grain layers. Be sure that each layer is completely covered with a thin layer of glue. Maybe you can think that if you make the core yourself, you don’t need to call it plywood.

You are wise to be concerned about wood movement. What is your objection to plywood or MDF? For stability, they are hard to beat.

If you insist on a solid wood core, use the most stable, quartersawn stock you can find. But MDF/ply would work better here, IMHO

8 inches, three layers, alternating grain, IMHO there will be no problem. Miter away.

Thanks guys. My main reason is solid wood is cheaper and I already have it.

It turns out what had was quarter sawn. So I ripped the board in half and got them milled up. I glued the panels glued up and ran them through the drum sander to make sure they were good and flat. I glues the 3/16th vaneer to one part of the core and and I glued the other two part of the core together. I will do the final glue up today.
