Abstract A power tool accessory table for attaching portable power tools to convert them for use as table-mounted tools, consisting of a removable plate to which the power tool may be attached so that its cutting element projects above the plate's top surface, and a tabletop with an opening in which the plate and attached tool are supported when placed therein from above. The table also has detachable side panels for enlarging the work surface, a remote switch for controlling the tool, an easily removable safety guard, and a friction locked rip fence for guiding workpieces.
