Abstract
A dovetail fixture for guiding a cutting tool in cutting mortises and tenons is described which can be simply used in cutting mortises and tenons. The fixture includes a molded base equipped with a horizontal table or work receiving surface and a sloped apron carrying spaced apart bosses defining a vertical work receiving surface. The surfaces are adapted to support work pieces in orthogonal positions with the end of a horizontal work piece in abutting relation with the end of a vertical work piece. Also included is a first clamping means adapted to clamp the horizontal work piece against the horizontal work receiving surface and a second clamping means adapted to clamp vertical work piece against the vertical work receiving surface in their abutting positions. A cutter guiding template is employed having at least one of its edges formed with a series of alternating guide fingers and slots. The template is adapted to overlie one of the work pieces and to be clamped thereupon in a position such that the outer edges of said set of slots and fingers is in alignment with the outer surface of the work piece.
