ABSTRACT:
An apparatus adapted for use with a power jointer having a bed and rotatable cutting blade provides precise, finish cuts on the end edges of boards so as to form good joints in picture frames, window casings, door casings and the like. The apparatus includes a fixed support rail mounted atop the bed and above the cutting blade. A holder, movable with respect to the bed along the support rail, clamps the board on end so that its end edge is disposed substantially parallel to and immediately above the bed for movement over the cutting blade to plane the end edge. Several holders according to this invention are utilized to obtain the desired angle of cut on the end edge of the board. Each separate holder includes at least one clamping surface disposed at an angle relative to the bed, e.g., 90.degree., 45.degree. or 221/2.degree., against which the side edge of the board is mounted to obtain a finish cut of the desired angle at the end edge of the board.
