Mortise and Tenon Setup Block

I always have a hard time getting my alignment just right when doing mortise and tenon joints for cabinet doors. With this I can easily adjust fence distance and blade depth quickly for perfectly centered cuts on my table saw or router table. The dimensions are 4" x 2" x 0.75". I designed this for use with ¾" lumber to achieve a ¼" by ½" mortise and tenon joint.
