ABSTRACT:
Miter joint cutting apparatus includes a base, and an adjusting member mounted on the base for relative sliding movement to a position along the direction of a saw line. A workpiece locating mechanism is mounted on the base for angular adjustment with respect to the saw line, and includes a pair of elongate guide boxes wherein each box has a lower lateral wall parallel to the base for supporting a workpiece with a forward end of the wall pivoted to the adjusting member, and a vertical wall extending from the lower wall. The lateral wall is coupled to the base via a projection which slides in a lateral slot in the base, as the guide box is moved by operation of the adjusting member. The forward end of the lateral wall is shaped so that an adjustment gap is defined between the forward end and the saw line over a range of angular adjustment settings for the guide boxes wherein the boxes pivot symmetrically over the range of settings relative to the saw line, including settings to either side of one where both boxes are perpendicular to the saw line. Accordingly, either an internal or an external miter angle cut can be defined by a guide box for a workpiece clamped in one position in the box.
