ABSTRACT:
The Adjustable Work Piece Clamping System permits a work piece to be held firmly on a work surface. It employs a clamping member having a spiral outer surface, this clamping member being pivotally attached to the work surface, preferably by a pin linked to the clamping member and received in one of a grid of openings provided in the work surface. It may employ other members adjustably attached to the work surface, preferably by pins, these members including a fence, an adjustable clamping member incorporating a pivotally attached shoe, and various other components set forth in the following specification. By employing the clamping member and these other components, a work piece of most any material may be firmly and quickly fixed on the work surface in virtually any position for cutting, face finishing or assembly, then easily removed upon completion of the operation.
