Patent ID: 7748420

Claim:
A dadoing system for guiding a router on a workpiece comprising: (a) a base constructed of rigid material with a substantially planar upper and lower surface, said base having a predetermined width, length, and thickness, having at least one open end for receiving a workpiece; (b) a plurality of squaring rails being of rigid substantially straight material, having a predetermined width, length and thickness, and said squaring rails being fastened on said base defining an area to receive a workpiece; (c) a first and second substantially straight, parallel, longitudinally extending tracks, being spaced apart on said squaring rails further defining the area for receiving a workpiece, and said tracks having calibrated measurement means associated with said tracks providing visible indication or location along each said track; (d) a plurality of sliding channel clamp tracks, having a predetermined length and being fastened to the upper surface of said base, each said track transversing the area for receiving a workpiece; (e) a plurality of sliding guide rails comprising of elongated, rigid, substantially straight stock, having at least one substantially straight horizontal surface, and at least one substantially straight vertical surface, transversely extending over the area to receive a workpiece, with one end of each said sliding guide rail being slidably engaged with said first track and the oppostite end being slidably engaged with said second track; (f) at least one sliding channel clamp being of elongated, rigid, and substantially straight material, having a predetermined length, width, thickness, and said sliding channel clamp being slidably engaged with said sliding channel clamp tracks; (g) at least one sliding guide rail track fastened to one of at least one said sliding guide rail; (h) at least one fliparm router stop, being slidably engaged with one of said sliding guide rail tracks; (i) a plurality of risers being of substantially straight, rigid material, having a predetermined length, width and thickness, each riser being fastened in a predetermined area of said base; (j) a plurality of sliding guide rail stops being slidably engaged with said first and second tracks; each said sliding guide rail stop being of a elongated, rigid material, having at least one substantially straight, horizontal surface and at least one substantially straight vertical surface, having a predetermined length, width and thickness, and the vertical side of said guide rail stops abutting one vertical side of said sliding guide rails.
