Abstract:
A dowelling jig adapted to be assembled from a kit of parts for guiding a drill to bore joint faces of work pieces for receiving dowels whereby a joint is formed when the work piece joint faces are brought together, the jig having:(a) an abutment plate having flat opposed sides against which a side face which is perpendicular to the joint face of a work piece can be abutted and held,(b) first and second generally planar drill guide plates each having a line of drill guide bores therethrough and extending along a line parallel to an edge face which is adapted to be clamped to the abutment plate,(c) spaced, corresponding transverse bores through a substantially central plane of each of the guide plates and through the abutment plate for receiving elongate securing screws,(d) each of the drill guide plates being about 15 mm thick, of hardened metal, of the order of 10 cm long, of rectangular form with all faces at right angles to one another and the line of guide bores being regularly spaced along the guide plates, the guide plates being identical and adapted to be assembled in mirror image relationship on opposite sides of the abutment plate,(e) wherein the securing screws are a clearance fit through the transverse bores, and(f) the jig further includes a clamping strip having threaded bores for screw threaded engagement with the screws and for clamping against an outer edge of one of the guide plates whereby the jig can be removably clamped in a selected assembled configuration.
