I'm going to build 4 bookshelves approximately 7 feet high and 3 feet wide. My initial thought is to use standard 2x10's for both the sides and the shelves (I like the look of thick shelves, the 2x10's are easy to buy at HD, and the 2" thickness should make for a sturdy bookcase). I'm also thinking of making the back of the bookcases out of 1/2 or 3/4 inch stain grade plywood. I haven't done this before, so I'd very much appreciate any advice, including thoughts on:
1) Am I making a mistake using 2x10's from HD or L's?
2) HD I believe sells doug fir and L's additionaly sells redwood. Any reason to prefer one over the other?
3) What's the best/easiest way to join the frame pieces? I was thinking of just using long screws. I don't have the skills or equipment for dados/rabbets/biscuits, etc.
4) What's the best/easiest way to attach the shelves? I was thinking of drilling plug holes so that the shelves could be adjusted later. What would I have to use to be sturdy enough for the weight of the shelves/books?
5) All other advice/thoughts appreciated!
Thanks in advance.
