Hello everyone. I'm new to the forum, and fairly new with woodworking as well. I have no aspirations to build fine furniture, but I do want to be able to build simple book shelves, built-ins, cabinets, etc.
I'm still learning the lingo too...so correct me if I'm wrong somewhere haha.
So, current project - book shelves for the wife. I've started building a set of shelves, approximately 5ft tall, 4ft wide, and 1ft deep. My question is :: will my shelves be stiff enough so they don't bow a noticeable amount. The shelves are 48" long, 12" deep. That's big I know. If I *need* to put a divider down the center I will, but I'd rather not if there are other ways to stiffen the shelves.
The shelves and sides are made of 3/4" plywood, and there will be a 2x1 (nominal) red oak face frame. The face frame is attached with pocket screws. The shelves are non-adjustable, they'll sit in 1/8" deep dados I routed into the sides, and they'll be secured with pocket screws as well. The bottom shelf will essentially sit on a base frame, so it's fully supported and I know it won't budge. The other shelves will have the face frame on the front for added stiffness.
Should I add another piece of 2x1 along the rear underside of each shelf as well? The shelves backing will be 1/4" ply that's nailed in with finishing nails, it's not really a load bearing piece.
I recently finished this little record player stand, the shelves will be a larger version. That's the plan at least.
Appreciate any advice/tips/etc!
