I asked my children if they want my old flat screen tv. My son wants it but has no place for it now so asked me to store it for him (ugh!) until he's ready. So I'm making a box for it-- 43" x 26" x 5". The box frame will be 3/4 x 7" pine, with two 1/2 ply sides (28 x 48). I will screw the pine box together but is it safe to pneumatically staple on the plywood sides?
