As an undergraduate reader for ME 12S, the introductory machine shop class at UCSB, I acted as a supervisor for students who were learning to use manual mills and lathes. Each class would use provided engineering drawings to create a single cylinder air motor out of various aluminum, brass, steel, and plastic stock. My role was to guide students through the process and ensure their safety when using machinery. This experience gave me proficiency in machining operations, teaching, and troubleshooting machinery.
