A dovetail joint jig for guiding a power tool for creating a dovetail slot in a first workpiece and a dovetail pin in a second workpiece includes a substantially flat main body portion having a slot portion on one side and a pin portion on an opposite side. The slot portion includes a pair of oppositely-disposed side projections which define a clearance space therebetween. A tapered router bit is guided along the inner edge of the side projections in order to create a dovetail slot in the first workpiece. The pin portion includes a slot- shaped portion whose planar shape coincides with the shape of the slot to be created in the first workpiece and accordingly in the preferred embodiment coincides with the shape of the tapered router bit. A generally cylindrical router bit is guided around the edge of the pin portion in order to remove material from the second workpiece and leave a dovetail pin which matches the dovetail slot in the first workpiece. The dovetail joint jig includes a longitudinal centerline and the main body portion, slot portion, and pin portion are each symmetrical about that centerline. By establishing a common centerline for the slot portion and the pin portion, the machined dovetail slot and the machined dovetail pin in the two workpieces will always have a proper and accurate fit. Additional dovetail joint jigs can be assembled onto a common tooling fixture and the centerline alignment remains unaffected.
