Building the jig and using it are very simple. The jig consists of a fixed fence and a movable fence with a registration pin. By sliding the adjustable fence towards or away from the blade of your table saw (or router bit in a router table) you can achieve an attractive utilitarian joint with a very large glue surface area.
