Design.
As a semester project for MEAM2010 Machine Design and Manufacturing, I designed and machined a functional Stirling heat engine modeled after a bike.
All components were machined using primarily CNC and manual mill and lathe operations. Primary component materials included C360 Brass, 6061 Aluminum, and 316 Stainless Steel.
