ABSTRACT:
A large panel surface planer is provided. The planer has a flat platform d as a mounting base. A pair of channel rails are clamped to the mounting base using c-clamps at the ends of each channel rail. A workpiece is secured to the flat platform using one or more pairs of back-to-back clamps which clamp both the workpiece and the flat platform. A pair of rectangular guide bars are clamped to and aligned orthogonally with the channel rails using a c-clamp at each end of each guide bar. A tool stop is also clamped at the channel rail-guide bar intersection providing both a tool stop and a spacer for alignment of the spacing between the guide bars. A cutting tool, such as a router, is then manually moved across the surface of the workpiece using the guide bar to hold the tool in position (both height and lateral position). After planing a particular set position, it is necessary to manually reposition the guide bar for the next cut and to continue sequentially until the entire workpiece has been planed.
