ABSTRACT:
An apparatus for use with a table saw to decrease a clearance of a surface surrounding a saw blade includes a throat plate that is inserted into an elongated slot that is provided in the surface of the table saw. The throat plate includes an enlarged opening with a pair of spaced-apart rails that, together, are adapted receive a replaceable T-shaped center portion. The center portion is cut by the saw blade as the blade is raised from below the center portion resulting in a space around the blade having a clearance that approximates the kerf of the blade. Screws secure the center portion in the enlarged opening. A pair of cam screws secures the throat plate in the elongated slot. A side to side adjustable splitter is attached to the throat plate.
