Barnes Velocipede #2 (1886)

This is probably the most efficient scroll saw ever built. It was so well-designed that it was still being manufactured out of aluminum in 2004, well past the heyday of human powered equipment. Our model is a type three, characterized by the use of its flat perforated belt. It has a twenty-four inch throat, an optional boring attachment, and a turning radius so tight that you can turn the blade around on itself and just leave a pinhole. It was designed primarily for use in pine and walnut, but it cuts through redwood like a hot knife through cheap margarine. We use it all the time in the construction of quality gables and window casements. Original cost: $18
