    Abstract: A sawing apparatus for cutting dove-tail notches in boards includes at least one saw for cutting one or more back cuts of the dove-tail notch and at least one saw for cutting one or more head cuts of the dove-tail notch. The head saw is configured to be able to cut head cuts that are angled both with respect to a horizontal plane and a vertical plane that is generally parallel to one of the sides of the board. This type of head cut creates a Scandinavian or Finnish dove-tail notch. The sawing apparatus may be mounted on a towable trailer, may include a generator for powering the saws, and may utilize band saws for cutting the dove-tail notches.
