ABSTRACT:
A combination tool including a table base, a carriage mounted on the base and having a screw jack for moving it forwardly and rearwardly relative to the base, a main table top carried by and movable with the carriage, and an auxiliary table unit having a planar surface through which the blade of a power saw projects. The auxiliary table may be mounted on the carriage in a first position, in which the auxiliary table surface forms an extension of the main table for conjointly supporting work pieces to be moved in cutting relation to the saw blade, with the screw jack functioning to adjust the spacing bewtween the saw blade and a fence carried fixedly by the base, and a second position in which the auxiliary table surface is disposed vertically at an edge of the main table top and the projecting saw blade overlies the main table surface for grooving, edging or shaping the edge of a work piece supported on the main table. The saw blade may also be adjustable laterally of its plane in the auxiliary table to vary its elevation above the main table top. Also, cooperating vise jaws may be mounted respectively on the carriage and on the table base, the carriage-mounted jaw being movable toward and from the base-mounted jaw by the screw jack.
