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 at either of two selectable pitches. The fixture includes a base equipped with a horizontal table or work receiving surface and a vertical apron or 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 the vertical work piece against the vertical work receiving surface in their abutting positions. A cutter guiding template is employed having one of its edges formed with a first series of alternating guide fingers and slots and having a second, opposite edge formed with a second series of alternating guide fingers and slots.
