Abstract
Abstract A cutting support and guide attachable to routers for use in cutting paneling. A workpiece is moved between two opposing plates, the top plate having a router mounted thereon with its cutting blade extending through an aperture in the top plate. A fence is disposed between the two plates and has a datum surface against which an edge of the workpiece abuts. The position of fence relative to the plates is adjustable, thereby determining the width of the strip to be cut from the workpiece. In one example, the two plates are connected by a series of connecting pins which pass through the cut in the workpiece as the workpiece moves through the guide.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
139 words
A cutting and support guide for attachment to a cutting tool for use in making a cut in a panel-type workpiece having a work surface and a reference surface intersecting said work surface by moving the workpiece past a cutting portion of said cutting tool, said guide comprising: an upper plate having an aperture for receiving a cutting tool and having means for attachment to said cutting tool; a base support plate opposite said upper plate, said plates having means for connecting said plates, in fixed relation to each other; a fence member disposed between said plates, said member having a datum surface for abutting said workpiece reference surface to direct the movement of said workpiece between said plates and past said cutting tool; and means for adjusting and securing the position of said fence relative to said plates.
Claim 2
Dependent Claim
