I need to make a pattern for a 10x10x4.5" box. I want to make it out of wood on my cnc mill. What kind of wood should I use? I was thinking of sandwiching a bunch of plywood together and just milling it out. Is this a good idea? I wanted to avoid having any joints in the material on the walls of the box, and if I glue and clamp the plywood together it should be plenty strong... right?
Or would I be better off making a rough box out of 2x6 lumber and cleaning it up?
BTW the box walls are .5" and I have given a 2% shrink allowance for aluminum.
