A dowelling jig (1) comprises a through-hole (5) for guiding a drill (18), abutments (12, 12) and cantilever springs (13, 13) for clipping the jig to one edge (10) of boarding (11) for drilling dowel-holes (2, 2, 2) in the edge, and a peg (9) for insertion in each dowel-hole (2) in turn for drilling the corresponding dowel-hole (3, 3, 3) in a face (14) of a second piece of boarding (15). The through-hole (5) extends between parallel faces (6) to which face (7) is perpendicular. Through-hole (5) axis is perpendicular to faces (6) and (19) while peg (9) is perpendicular to face (7). Abutments (12, 12) align face (19) of boarding (11) with face (7) for drilling of holes (2, 2). |
