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 buy one of these from just about any of the woodworking stores. Or save the money by making this one from shop scrap using the table saw fence. It's a quick build, taking most woodworkers an hour or so to complete. There is a full free build video for reference.
