Claim:
In a panel saw having a frame comprising a plurality of generally horizontal frame members and a plurality of generally vertical frame members defining a generally upright and rearwardly inclined planar guide and support surface for supporting large workpieces on one edge thereof in a generally upright position, said generally horizontal frame members extending in a length direction of the panel saw, and tool guide means for supporting a cutting tool for movement along a face of the frame transverse to the length direction to perform cutting operations on a workpiece supported and guided on the panel saw frame, the improvement comprising: a supplemental frame mounted to a front lower edge of the panel saw frame, said supplemental frame having first quick release mounting means on an upper end thereof; and an edge stop assembly removably mounted on an upper end of said supplemental frame assembly, said edge stop assembly comprising: edge stop support means extending in the length direction of the panel saw in closely outwardly spaced relationship to the guide and support surface of the panel saw and upwardly spaced from a lower edge thereof; second quick release mounting means on an underside of said edge stop support means cooperatively engaged with said first quick release mounting means; elongate guide channel means mounted on the edge stop support means and extending in the length direction of the panel saw; and edge stop means carried by the guide channel means for engaging an edge of a workpiece supported on the panel saw to locate the workpiece in a measured length direction relative to the cutting tool, said edge stop means including movable stop means having a first position out of the way of the workpiece and a second position engageable with an edge of the workpiece, said edge stop means being adjustable along the length of the guide channel means and releasably attached to it so that different edge stop means can be quickly and easily substituted on the supplemental frame assembly.
