I have found so many useful things on this site. I teach High School Precision Machining and several of the tools I've seen here will be making it to my classroom to be projects for my students. Keep up the good work! Any and all suggestions are welcome. What do you wish you had the opportunity to have learned at High School that you didn't? What are some of your best projects from then that really helped you understand machining and/or logical, critical thinking and planning?
