I'm looking to make some relatively large boxes for tools (currently one for a bunch of air tools, and one for a router, plunge base, and bunch of bits) out of 1/2" (~12mm) baltic birch plywood.
The sides will be joined with glued box joints, but I'm a bit unsure about attaching the bottom. My original plan was to cut a 1/4" (~6mm) deep groove about 1/2" up from the bottom on each side and end and inset the bottom panel (also 1/2" plywood) in that, much like a drawer bottom but glued in place. The other option is just to do a flush bottom glued in place and reinforced with some brad nails.
Essentially... thoughts on how the strength would compare between:
- a glued bottom set into a 1/4" deep groove, 1/2" up from the bottom
- a flush bottom glued inside the sides/ends and then reinforced with some brad nails
