re: Wood movement for a box

I’m thinking it’s probably fine. Might not want to ship it to the desert or the jungle, but tangential shrinkage on white oak is 10%, according to the wood database, which is enough that it might be a worry for flat-sawn wood, but the movement is half that in the radial direction, so quartersawn is almost certainly fine. I can’t tell for sure the grain direction from the photo, though.
