Steve, woodworking magazines offer plans for box joint jigs but the best jig available by far is the one from Oak Park. By using a different push block it is quick and easy to make angled and even compound angled box joints. Wood glides over the polyeurethane jig. At a price of $50 for the three jig set it can't be beat. You can also cut sliding dovetails with uniform spacing for table supports. Give it a look.
