ABSTRACT:
A system of machining a workpiece with a router bit includes a base plate for 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 the bit projecting through a bit opening. Two suction openings through the base plate to the work surface are connected to a common suction duct with the openings being spaced from the bit opening so as to draw material from the bit over the work surface along 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 fastening screw. When using a centering system, the holes in the end plate can be aligned with the respective slot in the respective disk and the router clamped in place at a centered location.
