JOINT SPECIFICATIONS, GUIDE & BIT SELECTION

Directions: Joints routed with a single bit are shown shaded. In addition to the joint sizes listed in the charts, any tenon
width (mortise length) can easily be achieved by using the jig’s quick-acting table movement and limit stops as described
in Chapter 6, Longer and Shorter Joints. By using combinations of machine tool bits, even more sizes of small and miniature
joints may be routed. See information on small joints in Chapter 4.
