Abstract: A precision miter gauge that consists of a sine-plate assembly mounted on a guide bar for engagement in a conventional table-saw miter slot. The sine-plate assembly comprises a stationary plate substantially perpendicular to the guide bar and a hinged plate pivotally connected to the stationary plate by a hinge pin having an axis of rotation disposed at a predetermined distance from the hinged plate, so as to form a variable angle between the two plates. A gauge block adapted to produce exact predetermined angles is positioned between the stationary plate and a reference pin pivotally coupled to the hinged plate and having an axis of rotation disposed at the same predetermined distance from the hinged plate as the hinge pin's axis. As the gauge block is firmly secured between the reference pin and the stationary plate, the hinged plate provides a solid and precise fence for cutting a workpiece at the selected angle.
