A duplicating system, especially for use with a multipurpose woodworking machine capable of performing lathe turning operations. The system includes a support table, a carriage adapted to be slidably mounted on the machine, and a locking rack and pinion for raising and lowering the table relative to the carriage. A tool support is positioned on the table and includes a base having a low friction pad for engaging the table top, a follower for contacting a pattern, and a multi-edge cutting tool rotatably mounted on a tool rod for engaging a workpiece. An insert guide is mounted on the tool rod to hold the cutting tool in position. The base has a set screw which engages a circumferential groove in the shank of the tool rod so that the cutting tool can be quickly and accurately positioned relative to the follower. The system also includes a pattern support frame which includes a channel, a pair of stanchions for attaching the channel to the machine above the workpiece, and a pair of brackets which are slidably adjustable along the channel and include clamps for engaging a flat template and spindles for engaging a three-dimensional model. The clamp is adapted to hold a template either parallel to or perpendicular to the axis of the workpiece for spindle or face plate turning, respectively. The channel also supports an adjustable chip shield.
