This simple, affordable jig makes light work of 1/2'' and 3/4'' box joints—ideal for making anything from boxes and drawers to beehive ''supers.'' Leigh's elliptical e10 bushing lets you adjust the fit by as little as 0.001'' for tight joints that slide together with a whisper. The flip stops provide the correct offset for the pins and sockets—just flip the stop open to go from routing sockets to routing pins. The comb template is attached to a shop-made beam, which can be made out of 2 pieces of 3/4'' MDF glued together, or a length of 2x4 jointed square.


  • Make fast, accurate 1/2'' and 3/4'' finger joints on boards from 1-7/16'' to 17-13/16'' wide
  • Useful for anything from boxes and drawers to casework for small furniture pieces
  • May be used with handheld or table-mounted routers (table-mounting requires an insert that accepts a standard 1-3/8'' guide bushing)
