Abstract

An improvement is set forth in a sawing apparatus having a workpiece support structure and an operator moveable electrically operated saw having a first normally biased off switch controlling application of electric power thereto, the switch being positioned to be controlled by the hand of an operator which controls movement of the saw. The improvement comprises a device adapted for gripping, positioning and clamping a workpiece relative to the workpiece support structure and a second normally biased off switch connected in series with the first normally biased off switch, the second switch being positioned to be controlled by the off hand of the operator while the off hand is utilizing the device. Since both hands of an operator must be holding onto normally off switches and since both switches are in positions removed from the area of movement of the saw blade, the operator is protected from accidently cutting himself. Yet, the device allows the operator adequate control of the workpiece being cut and further allows the radial arm saw to function as a ripping saw without interference.
