  • Publication number: 20030075033
    Abstract: A workpiece support accessory in the form of a sloping extension panel is coupled for pivotal and horizontal displacement relative to a table-mounted power saw for supporting oversized stock. When an oversized piece of stock is cut, the extension panel prevents the workpiece from inadvertently falling or twisting. A horizontal roller at the delivery end of the workpiece support accessory reduces the friction between the oversized stock and work surface allowing for easy movement during the saw operation. The operator can adjust the horizontal placement of the workpiece support accessory, the slope angle of the extended support surface, the elevation of the horizontal roller and the separation between the horizontal roller and the delivery end of the extension panel.
