ABSTRACT OF THE DISCLOSURE A doweling jig requiring minimal adjustable for drill- ing multiple like-size mating dowel pin holes in workpieces of varying thicknesses, dependent on the configuration of fixed position drill guides or bushings. The jig is generally of channel construction, with reversible clamp- ing for use on double jigs of one or two channel. Each side of double jig may differ in configuration and size of its fixed position drill guides. Of the many contructi methods, two use interchangeable heads containing one or more drill guide configurations. The use of pivotal stop disks at each end of the channel lessens visual alignment.
