ABSTRACT:
A jig used to support and guide a cutting tool has a base frame provided with an elongated support. Mounted on this support is a plurality of guide fingers which collectively serve as a template for the cutting of joint members in boards. The guide fingers are individually secured to the support so that the lateral spacing between the fingers is adjustable. Along one side edge of the support, the overhanging ends of the fingers are shaped to allow the cutting of common joint members. Along the other side edge of the support, the overhanging ends of the fingers are shaped to allow the cutting of complementary joint members. The jig has a clamping arrangement which allows the boards to be clamped to the base frame with the board ends disposed in selected positions relative to the shaped ends of the fingers. By suitable adjustment of the guide fingers, it is possible to provide the board with joint members of varying size and spacing as is sometimes desirable although the fingers can just as readily be arranged to produce joint members of uniform size and regular spacing.
