Design Brief: Design a chair for a specific task using only one piece of 8' x 4' plywood. No fasteners of any kind. Only wood joints can be used.
I designed a reading chair for the mornings and evenings. A chair that one would sit on to read the morning paper before going out into the day, or to read a novel at night before bed.
Kerf is the width between two teeth of a saw blade, and is also known as a method by which one can bend plywood. Cutting through most of the plys weakend the plywood so that it can be bent agianst a jig. Two pieces were kerfed and then laminated together to strengthen the seat pan. Perfecting the technique took many tests as the the depth and spacing of the cuts determined how well the plywood could be bent. Too deep and close together the plywood would snap under pressure. Too shallow and far apart the plywood would not accept the curve and break when clamped to the jig.
