Abstract
A woodworking apparatus with a base for retaining a work piece and a bridge for mounting a tool. The bridge is pivotally mounted to the base by two arms and is adjustable towards the top, side and bottom faces of the work piece. Since the bridge, and hence the tool, is adjustable within a wide range of different angles, the need for multiple bit pieces is greatly reduced. The woodworking apparatus further includes a pivot pin, attachable to the base and to the work piece, for pivoting the work piece along an arcuate path with a predetermined radius measured from the pivot pin to the tool. The pivot pin is movable along a guide within the base, allowing a rough adjustment in the radius of the arcuate path. Further, the guide itself is movable along the base, allowing a fine adjustment in the radius. Because of this fine adjustment of the radius, the time-consumption and imprecision inherent in the conventional techniques in the art of creating a curved work piece with a constant radius or with multiple cuts along the same piece has been greatly reduced.
