Dowel jig

A dowel jig for positioning first and second workpieces to permit the drilling of corresponding dowel holes therein comprising a first member having a flat surface and a wall extending essentially perpendicular to said flat surface, said wall including at least a first bore hole therein of a predetermined diameter which defines an axis extending essentially parallel to said flat surface, a second member slideably supported on said first member adjacent said flat surface and slideable in the direction of said axis, said second member having an upper surface facing said flat surface of said first member, said second member including at least second and third bore holes therein of substantially the same diameter as said predetermined diameter of said first bore hole, said second and third bore holes each defining an axis, the axes of said second and third bore holes extending essentially perpendicular to and intersecting said axis of said first bore hole in said first member, and locking means for releaseably locking said second member at a desired position with respect to said wall of said first member to permit simultaneous drilling of two aligned holes in the edges of said first and second workpieces through said second and third bore holes, respectively, said wall including two additional bore holes therein spaced laterally thereacross with said first bore hole, said three bore holes in said wall each having a different diameter, each said bore hole in said wall being spaced a predetermined distance from said flat surface, said second member including two additional bore holes laterally aligned with said second bore hole and two additional bore holes laterally aligned with said third bore hole, said upper surface defining an imaginary base line extending transversly thereacross essentially perpendicular to the axis of said first bore hole, each bore hole in said wall including a corresponding bore hole on one side of said base line and a corresponding bore hole on the other side of said base line, each said set of corresponding bore holes having substantially equal diameters, said corresponding bore holes in said second member having axes which extend essentially perpendicular to and intersect the corresponding bore hole on said wall.

A dowel jig comprising a first member having a flat surface and a wall extending essentially perpendicular to said flat surface, said wall including a first set of three bore holes each of a different predetermined diameter which are spaced transversely across said wall, the center of each said bore hole being spaced a predetermined distance from said flat surface, each said bore hole defining an axis, a second member removably slidably supported adjacent said flat surface and defining an imaginary base line extending transversely thereacross, said second member including a second set of three bore holes spaced apart on one side of said base line and a third set of three bore holes spaced apart on the other side of said base line, each said bore hole in said first set including a corresponding bore hole of said corresponding different predetermined diameter in each said second and third sets of bore holes such that the axis of a given one of said bore holes in said first set is perpendicular to and intersects the axes of the corresponding bore holes in said second and third sets, the centers of each corresponding bore hole in said second and third sets of bore holes being spaced from said base line by said predetermined distance of said corresponding bore hole in said first set of bore holes, said second member including a set of three slots in an edge thereof, each said slot being in alignment with one said corresponding bore hole in said second and third sets, and locking means for locking said second member in a given position when in said first member, said locking means permitting said second member to be removed from said first member.
