Large toy box: fixed or floating bottom?
I am building a large (48" wide, 22" deep, 20" tall) toy box for my granddaughter. The sides are 5/8 Baltic Birch plywood. The bottom is to be 3/4 Baltic Birch plywood. My question is: should the bottom panel float in a dado or can it be tight in the dado and glued/dowelled?
The advantage of fixed is that the bottom will help to keep this large box from racking, but will the ply expand and cause issues?
The outer corners are flanked with vertical 1x4 cherry boards that are joined to each other with a finger miter and these corner boards will be glued and doweled to the corners of the birch ply box.
Many thanks for any advice.
