In the art of making mitered frame members on a work table associated with an operatively mounted mitering saw, an improved device for use in mitering rabbeted metal type and wood type stocks, comprising: (A) a portable panel having a forwardly-rearwardly extending slot to receive the mitering saw; (B) a panel-mounted abutment means including, (1) for metal stock, a rear abutment wall extending on and along the rear side of a vertical plane which converges forwardly toward the panel slot at an angle of about 45 DEG on the rear side of said plane, and, (2) for wood stock, a front abutment edge extending on and along the front side of a parallel vertical plane, which converges forwardly toward the panel slot at an angle of about 135 DEG on the front side of said parallel plane; (C) common scale means associated with said abutment means to provide one set of length dimension calibrations for both types of stock; and (D) common stop means associated with abutment and scale means for determining the operative mitering position required to provide each stock with a mitered rabbet surface length equal to a desired mat-length plus a tolerance.
