I recently purchased a maple workbench, 26"x84". It is a little over 2" thick and I'd like to beef it up a bit. My question is whether it is necessary to laminate another layer under the entire bench, making it 3"-3 1/2" thick or would it be sufficient to just beef it up on the edges and under the bench dog holes. I will be using this bench for planing, sawing and assembly as I have a small "joinery" bench that I use for chisel work since it is taller and thus easier on my back.
