Large roll out drawer material
OK, I'm fairly new to wood work. Mostly just some shop benches and cabinets so far.
However, I recently jumped in and built a king platform bed with drawers. The finish is far from perfect, but it was a lot of fun and I have learned a lot.
Anyway, I built the bed with a center opening from the foot to run a large drawer into. The opening is 25" wide and 17" tall. My plan is to build a large drawer to use for items like a bedspread, Christmas throw pillows, etc. It will all be light items. The "drawer" will actually have non-castering rollers on the bottom rather than drawer slides. I will build the complete drawer box and attach a walnut front to match the rest of the bed.
My plan is to build the outside of the box 3/4" to 1" less than the 25" opening and install a runner on each side to guide the drawer in straight. So, by the time I allow for the rollers and some space at the top, the drawer should be about 14 1/2" high, 24" wide and I plan to build it 48" deep.
My primary question is what material thickness i should use for such a large drawer.
I have enough 1/2" baltic birch ply to use for the sides, ends and bottom. I also have enough 3/4" ply to use that for the sides and ends and then 1/2" BB for the bottom. Would 1/2 all around be sturdy enough for such a large drawer? Or should I go with the 3/4"?
Does anyone see any other problems with my plans?
