ABSTRACT:
An apparatus for cutting dado cuts in a board includes a first base member that includes an adjustment for surrounding a fence. A pair of rods extend away from the first base member and are attached to a first rail. A second base member includes a pair of spaced apart holes through which each of the pair of rods passes. A locking lever is used to secure the second base member in position relative to the pair of rods. The second base member is mounted over the rods in either of two ways. Each side of the second base member provides an indication as to where and edge of the dado cut will occur in a board. The width of the dado cut is readily adjustable by urging the second member into the desired position and by actuating the locking lever.
