Abstract
A router plate for use with a router having a planar surface and an arbor projecting therethrough. The router plate comprises a flat plate member having an opening extending therethrough with a rabbet flange extending inwardly from the outer perimetric edges of the opening. The invention also includes a removable insert that resides within the opening in the router plate and is supported by the rabbet flange. A plurality of removable inserts may be provided, each having a differently sized aperture for accepting a particular router bit. The insert appropriately sized for a particular application is detachably mounted to the router plate.

A router plate for use with a router having a planar surface and an arbor projecting from said planar surface, said router plate comprising:
- a flat plate member having an opening extending therethrough, said opening having first and second axial ends and circular outer perimetric edges, an enlarged portion of said opening being adjacent said first axial end, a rabbet flange extending inwardly from said outer perimetric edges adjacent said second axial end;
- and
- a raised O-ring disposed between said first axial end and said rabbet flange.
A method of detachably securing one of a plurality of removable inserts to a router plate for use with a router having a planar surface and a router bit mounted on an arbor projecting from said planar surface, said router plate having a flat plate member with an opening extending therethrough, said opening having first and second axial ends and circular outer perimetric edges, an enlarged portion of said opening being adjacent said first axial end, a rabbet flange extending inwardly from said outer perimetric edges adjacent said second axial end, an O-ring disposed between said first axial end and said rabbet flange, each of said inserts having a top surface, a bottom surface, and a side edge with a grove between said top and bottom surfaces, said method comprising the steps of:
- inserting one of said removable inserts into said opening;
- said bottom surface of said insert being supported by said rabbet flange and said grove receiving said O-ring.
A woodworking apparatus for use with a router having a planar mounting surface and an arbor projecting from said planar mounting surface comprising:
- a router plate mounted on top of said planar mounting surface, said router plate having an opening extending therethrough, said opening having first and second axial ends and circular outer perimetric edges, an enlarged portion of said opening being adjacent said first axial end, a rabbet flange extending inwardly from said outer perimetric edges adjacent said second axial end;
- a removable insert having a top surface, a bottom surface, and a side edge between said top and bottom surfaces, said insert being disposed within said opening with said bottom surface being supported by said rabbet flange;
- and
- an O-ring being disposed between said outer perimetric edges of said router plate and said side edge of said insert.
