Abstract: A compound miter box is provided wherein the saw guides are pivotable about a vertical and a horizontal axis. Each saw guide includes a retaining mount having a concave bearing surface defining a locating tab thereon. A saw supporting arm is pivotally mounted to the underside of the saw bench. The arm includes a plurality of tab receiving depressions therein. Each tab receiving depression corresponds to a predetermined angle between the saw guides and the saw bench. A user may then select and secure the locating tab in a tab receiving depression corresponding to the desired predetermined angle between the saw guides and the work supporting surface of the bench.

Abstract: A miter box is provided with a simple demountable and adjustable board stop which operates in conjunction with the horizontal upper edge of the miter box backstop to position a board, such as a piece of cove molding, in an acute vertical angular position with respect to the miter box table which allows the board to be cut at the compound angle required for a mitered butt joint in which the cut pieces are mounted at the same relative angle in which they are positioned in the miter box. The box also includes a simple frictional locking mechanism to set the pivotable saw carriage in any selected horizontal angular position over the full range provided by the miter box.
