Along with stone, clay and animal parts, wood was one of the first materials worked by early humans. Microwear analysis of the Mousterian stone tools used by the Neanderthals show that many were used to work wood. The development of civilization was closely tied to the development of increasingly greater degrees of skill in working these materials.
If your shop is long and narrow, option 2 provides maximum space to the left of the fence for handling large sheets of plywood. If you often work with full sheets of plywood or other sheet goods, you might want to build the table saw into an extension table surround, as San Diego woodworker Pat Curci did in his small shop (see the photo). The surround offers support for large panels, as well as provides an ample work surface near the saw.
The thickness planer can joint a board's face. On this simple jig, the stock is supported by twin rows of wood screws driven into a platform and adjusted to meet the varying clearances on the underside of the board. The stock rides the sled cup side up. Slide the board slightly sideways to adjust the screws, then seat it firmly on the screw heads for planing.
