Magnetic auxiliary fence jig
To avoid drilling into your expensive tablesaw fence to attach jigs, mount them instead to a wooden fence attached to your real fence with rare-earth magnets. Because the magnetic attachment grabs the steel body of the fence, you don't have to work around clamps. With no clamps or screws, installing and removing the fence takes only seconds.
Adhere the magnets by cutting a filler strip of wood to fit on top of the fence between its faces. Then, bore holes through the filler strip to fit the magnets, glue and screw the strip to the auxiliary fence, and epoxy the magnets in the holes. To prevent the jig from sliding as you feed stock through the saw, attach a steel L-bracket end stop to the jig, where shown.
