ABSTRACT:
An assembly for facilitating the cutting of matching panel joints includes a base body which is adapted to be secured to the lower surface of a router or the like and has a lower ramped slide surface defined therein, and a slide member having a topped ramped bearing surface defined therein for contacting the lower ramped slide surface in the base body. The base body and slide member are mounted for sliding relationship relative to each other so that a lower bearing surface on the slide member is vertically adjustable relative to a corresponding lower bearing surface on the base body. In operation, the base body and slide member are adjusted so that their respective bearing surfaces differ in elevation to a degree equal to one-half the wavelength of a cutting bit to be used in the router. In this way, a first cut may be effected by using the bearing surface in the base body, and a complementary second cut may be formed by using the bearing surface on the slide member, without the need for readjustment of the assembly between cuts.
