I skipped a step in the photos which was to build the surround around the saw. It provides the vertical structure between the saw base, the work supports and the top shelf. This is where the measurements and calculations paid off. In addition to the surround, this picture shows the dry fit of the work supports on each side. My basement has a nice little bump out which allows the saw to sit flush with the walls on either side. Without that, the whole thing would have to sit further out from the wall /forums/images/graemlins/smile.gif
