ABSTRACT:
A lever lock hold down mechanism for clamping workpieces to a miter gauge is disclosed as including a workpiece supporting base or bar and a generally vertically directed workpiece supporting head extending upwardly from the base or bar. Extending further upwardly from the workpiece supporting head is a clamping frame having a vertically adjustable clamping rod slidably mounted to the frame and also having a clamping foot at its lower end. A spring biased apertured gripper plate is mounted over the rod in the vicinity of the clamping frame, and a lever lock is pivotally mounted to the clamping frame for engaging and disengaging the apertured gripper plate relative to the clamping rod. The lever lock and apertured gripper plate is configured, arranged and dimensioned so as to be moved out of engagement with the rod when the lever lock is moved upward to a released position, the lever lock also being capable of being pivotally moved into engagement with the apertured gripper plate so as to apply continuous gripping engagement to the clamping rod for clamping workpieces through the clamping foot against the supporting base and head.
