A good buddy of mine brought me some 1" red cedar lumber from Mississippi. I am planning on making up some bottom boards to fit under my SBB. Reason being my SBB's don't have a panel or a way to close them up to do OA treatments.
Any advice? I was going to just make three sides, 1" x 2 - 3" then dado the side supports and then slide in the bottoms.
Any advantage making the supporting sides bigger than 2"?
