<p>A doweling jig requiring minimal adjustment for drilling multiple like-size mating dowel pin holes in workpieces of varying thicknesses, dependant on the configuration of fixed position drill guides or bushings. The jig is generally of channel construction (10), with reversible clamping for use on double jigs of one or two channels. Each side of a double jig may differ in configuration and size of its fixed position drill guides. Of the many construction methods, two use interchangeable heads (14) containing one or more drill guide configurations (15). The use of pivotal stop disk (21 and 22) at each end of the channel lessens visual alignment.</p> |
