Abstract
A table saw is disclosed comprising a main saw unit and an air table attachment. The air table is mounted adjacent a main support surface of the main saw unit, and includes a body portion and a generally planar table top. The body portion has a plurality of subsections formed therein. The table top is substantially coplanar with the main support surface, and is attached to the body portion to cover the subsections so that a plurality of holes through the table top communicate between the subsections and the exterior. A shop vacuum produces either a partial vacuum or a stream of pressurized air, and a manifold attached to the body portion selectively communicates the vacuum or stream of air to one or more of the subsections to respectively produce either a suction force or a supporting air cushion over a variable portion of the table top. Preferably, the air table is movable along the front and rear guide rails in a direction transverse to the direction of rotation of the saw blade. The air table can also be moved from one side of the rotatable blade to the other side to accommodate the workpiece.
