(Ken Yee) wants to know:
I've found 1/2 plywood amazingly strong. I've got some knock-down
bookshelves, with about an 18" span, the work well as chairs. They'll
take around 300 lbs, no prob.
I'd support a piece, so it's as wide as your shelf would be, and put
weights on it, and see how it does. Of course, it may look OK, but
still bow a bit in time. If you're unsure, you can either go to 3/4",
or run a brace or two on the bottom side. You could probably even add
the brace later. Or, you could laminate two pieces of 1/2" - I do that
at times, because that's all I've usually got on hand. One of my kids
gave me a big chunk of that laminated stuff that's about 2" thick. No
prob about that stuff bowing, but it's almighty heavy.
