Abstract: A wood carving attachment that mounts onto a table saw provides a carriage for holding a pattern, and a workpiece that will be engaged by the circular saw blade to duplicate the pattern configuration on the workpiece. The pattern and workpiece are mounted on opposite ends of a carriage that pivots about an rocker axis generally parallel to the axis of rotation of the saw blade, and also is movable in direction along the axis and at the same time the pattern and the workpiece are both rotated about axes generally parallel to the rotational axis of the saw blade. A tracer wheel riding against the pattern will cause the carriage to be tilted about its rocker axis of the support as the pattern is moved along the rocker axis and rotated against the follower wheel so that by movement of the carriage the surface configuration of the pattern is duplicated by the saw blade engaging the workpiece.
