Hey folks. I want to build a shelf as you see it in the sketchup rendering. I'm using pine which I have in abundance at the moment and I want to use relatively basic joinery. The shelves will be solid wood so I was wondering how to attach them to still allow for expansion and contraction. I was thinking of pocket screws hidden under the shelves and screwed into the stiles of the bookcase sides. I want to make sure that the front of the shelves stay put, so could I still use pocket screws at the back of the shelf but maybe back them out a bit to leave some wiggle room?
While I have your attention , do you think tounge and grooved or shiplapped boards for the back would look OK in a simple design like this? The other option I was thinking of was AC plywood or something similar.
Thanks for the help!
