I'm working on building a simple entertainment center, and would like some advice. The sides and back are to be 1/2" red oak plywood, and there will be three shelves the width and depth of the entertainment center (minus the sides).
I plan on putting a large screen TV that's about 100-200 lbs on the second shelf, and was wondering if the 1/2" plywood sides would be sufficiently strong. The shelves themselves will be 1/2" plywood supported by a 1x2 poplar frame with 1x4 red oak as a border. The top shelf will carry some wonderfully heavy equipment, too. It'll be less than 200 lbs, I think.
Any suggestions on attaching the shelves to the plywood sides? 1/2" isn't very much material for a screw to grab in to from the inside, and if a screw was inserted from the outside it'd show.
On a related note, this project marks my first real venture into hardwoods. I had a good experience with the hardwood store, but learned that 10' long boards just won't fit in a Prius. Next time, I'll peruse the shorter boards /first/ and save myself a trip back in the truck.
