Bah!! Science?? Witchcraft, I say!!!!

@Satyrnine If you are going for the natural look with your cab, why not use baltic birch ply and just veneer the **** out of it. You'll get the functionality and strength of ply but the look of walnut.
Definitely thought about that. Hell, I have a bunch of Walnut burl veneer that even crossed my mind, but that's too extreme. If we did veneer, I think I'd have to cover the corners/edges with hardware, since that joining of thin veneers would be a weak spot for chipping and/or ugly unless it was done very well. Plus veneer can be a pain in the ass to apply.
