Abstract
The invention provides a woodworking duplicator which is adapted to be attached to a standard radial arm saw. The device allows a rotating cutting tool and a stylus to be movably supported allowing the user to trace a pattern with the stylus while cutting the pattern into a work piece with the cutter. The invention provides a duplicator that may be mounted to a radial arm saw wherein the duplicator includes elements that may be moved in five different directions. The invention also provides a duplicator having a stylus and a cutter that may be easily locked into different parallel positions so that the user of the duplicator may more easily trace the item being duplicated. The invention also provides a duplicator that supports the weight of the stylus and cutter tool.
