Abstract: An improvement is set out in a table saw arrangement (10) which includes a generally vertically oriented generally circular rotatable saw blade (12) extending upwardly through a slot (14) in a work table (16), which work table has a fence (24) generally parallel to the slot (14), which fence is adjustably positionable on the table in parallel relationship to the slot (14). A leaf (36) is attachable against an edge (18) of the table (16) which is parallel to the slot (14). The leaf (36) has an opening (40) and a skirt defined by peripheral portions (44,46,48 and 50). One edge of the leaf (36) can be fastened against the edge (18) of the work table (16). An adapter plate (76) is mountable beneath the leaf (36) and is also mountable to any of a number of power tools. The adaptor plate (76) is also mountable via spacers to the leaf (36).
