I am building my first piece of furniture which will include what is basically a book case with a middle partition to create cubbies. The middle partition is 3/4 plywood. I am planning to dado the shelves into the sides of the frame (I don't want adjustable shelves). The trick is how to attach the shelves to the partition board in the middle b/c there will be shelves attached on both sides. If I dado 1/4 on 2 sides of the 3/4 plywood, am I asking for trouble, or will it be strong enough with the remaining < 1/4 wood that is left - the vertical board is not load bearing but will it bow or something? Another though I had was to dado one side and then drill holes through the dado to put dowels into the shelf on the other sides. Are there any expert opinions out there? Thanks!
