Abstract
Present invention teaches to build a woodworking table saw where, a splitter/riving knife move with the saw blade in a synchronized manner, with an idle gear engaging in planetary circular action around a fixed quadrant gear and the outer gear teeth portion of a support arm, so that any height adjustment or angle tilting done to the saw blade will result in the same movement of the splitter/riving knife, maintaining the constant linear difference (usually 5 mm) between the saw blade and the splitter/riving knife. In addition, to facilitate the installation, changeover, and/or removal of the splitter/riving knife, a spring pressure plate mechanism is used, along with lug bolts and a spring loaded secure pin device to easily set the splitter/riving knife in a pre-set position without using tools and in shorter time duration.
