I am going to cross post this on several forums. So please forgive me if you read this again. I'm looking at building some bookshelves of sorts. They would be boards (sanded and stained) and laid on those brackets (?). I hope that makes sense. I know that some people here have built bookshelves. I am hoping they will chime in and tell me how they keep them from sagging.
My questions are this:
How thick does my wood need to be to prevent sagging? And/Or how far apart do the brackets supporting the wood need to be to keep the shelves from sagging and holding the weight?
I recently saw this information - sunset magazine? Better homes and garden? I don't know and can't remember. I've searched frantically for it. Can anyone help?
