I'm building a 3'x5' desk out of 1" thick end-cut bamboo plywood from Smith and Fong and some adjustable legs from IKEA. Should I add some structure to the bottom to keep it from sagging, or should it be okay at that size without sagging?
I've never heard of bamboo ply - interesting... but as Chris stated, 1 inch is thick ply... but if you're going to put stacks of books and desktop computer with a big monitor... well now you're stressing that ply and it wouldn't hurt to add a skirt and maybe even a cross member or 2 on the underside if your design can accommodate the extras. Rule of thumb is "don't skimp and be sorry - overbuild and never be sorry" :smile:
