ABSTRACT:
A dowel jig has two clamp rails of equal length pivotally attached to two cross-bars of equal length so form a series of parallelograms when the cross-bars are pivoted. A bushing holder bar attached to the center of each cross-bar, contains several drill bushings equally spaced apart from one another. Thus, when the rails are clamped to the sides of a workpiece the drill bushings are automatically centered upon the top of the workpiece. Further, the rails are located substantially below the bottom surface of the bushing holder bar and thus guidelines on the bushing holder bar and location marks on the workpiece are visible by the user for alignment.
