That's the math I came up with. Depending on drawer width/depth, you could get anywhere from 8 to 12 4" tall drawers out of a 5' x 5' piece of 1/2". However, someone buying plywood in bulk at a cheaper price, could plink these out all day long at a competitive price for local suppliers or shops. Someone with a CNC setup could even do dovetails for pre-sized kits pretty reasonably. If priced reasonably I'd definitely buy them pre-milled. Might be worth looking at a bit deeper for some of you to make a buck or two on. Someone like Larry might be able to turn them out pretty quick with that woodmaster of his.
