In Peter Lieber's thread on 'Modular Layout Assembly' (1-07-09) and questions of connecting the modulars together the ending problem hinges around the swelling of the wood underlayment. By the way, Peter has built a very nice table.
My question is how much of the swelling problem will go away if a sheet of 2" pink foam is used, plus all foam risers, etc.? And if the design used a sheet of 3/8" plywood under the 2" pink foam instead of a heavier underlayment of possibly 3/4" wouldn't the expansion-contraction problem even be less? Maybe non existent? Maybe a part of the discussion needs to include the outside framing which would be 3/4" 1x4's?
Still trying to solve the problems before the build.
Thanks for all of your thoughts and input.
