An alloy jig with hardened steel bushes which will produce E, L and T joints with either 6mm, 8mm or 10mm dowels. Somewhat different to the Dowelmaster in that it has a clamp included which allows the work to be accurately located and drilled for greater degrees of accuracy. The jig is supplied complete with two clamps to ensure that the work cannot move when clamped and is equally spaced-especially useful when drilling large boards. Best used with a (lip and spur) dowel drill and depth collar. All-round accuracy in work up to 30mm thick.
