Most plans come without joinery methods because there are so many ways to accomplish the task. All plans have complementary free YouTube videos showing you how I performed the task for that particular piece. If you'd like to explore other joinery options, you're welcome to reach out to me via email or join the forums where you can get input from multiple people, including myself, on the best joinery methods for a particular project. I try and use different joinery methods when I can, primarily to demonstrate how to do them.
You could certainly spend your hard-earned money to purchase one of these, but it's much easier and cheaper to utilize some of that shop scrap to build an over-the-fence jig for the table saw. I know we all remember seeing Norm use one of these in nearly every episode, and this version is easily just as accurate.
