Tablesaw Miter Jig

To build this jig, first place one miter-slot guide into each slot on your saw table. Align the 1/2″ plywood base on top of the guide, long edges perpendicular to the miter slots. With the plywood resting on the table saw surface, drill 5/32″ shank holes through the plywood and into the guides just far enough to mark their positions. Remove the plywood and guides and drill 7/64″ pilot holes through the guides. Reposition these pieces on the table saw, and attach the guides with countersunk #8×1″ brass wood screws. Drive the screws about halfway through the guides, and lift the assembly off the table. Drive the screws completely, and sand off their protruding tips. Again, place the jig onto the table saw surface, turn on the saw, and cut a kerf about halfway across the width of the plywood.
