<p>A system of machining a workpiece with a router bit includes a base plate far mounting in a recess in a router table having a work surface over which the workpiece is to be moved. The router is mounted underneath the plate with th e bit driven about a bit axis which is at right angles to the table surface and projecting through a bit opening. At least one and preferably two suction openings through the base plate to the upper surface of the base plate are connected to a common suction duct with the suction opening or openings being at a location spaced from the bit opening so as to draw material from the bit over the upper surface along the cut shape in the workpiece. The end plate of the router is attached to the base plate by a plurality of rotatable disks each having a slot for receiving a fasteni ng screw. When using a centering system, the holes in the end plate can be aligned wit h the respective slot in the respective disk and the router clamped in place at an accurately centered location.</p> |
