"Joints That Swing" was the name of the class, and Bill Anderson was the instructor. Bill is unbelievable with both a chisel and a plane. We learned how to make a rule joint and a barrel joint. The only electric tools in the shop are the lights. All cutting is done with wickedly sharp planes, chisels and hand saws. If you get a chance, I highly recommend taking one of their classes (see: https://www.woodwrightschool.com ).
