I am a High School shop teacher and would like to build a board of all of the significant joints that my students would encounter and/or use. When I was in high school myself I remember having a 4x4 piece of plywood on the wall that was painted a light green color and had joints both assembled and disassembled. At the time I didnt give it much thought but the teacher probably didnt know much about it himself. I have not been able to find anything by doing a google search. I would like to make a similar board for my room and was wondering what joints everyone thought would be pertinent for high school shop students to know. Thanks for any input, I will try and post a pic when I get it completed. Thanks for the suggestions.
