Oscillating Air Engine
Designed an oscillating air engine at George Fox — with no design instructions given. Researched how the engine worked, then produced SolidWorks drawings detailed enough to machine from, plus SolidWorks models of every part and the assembly.
Design choices for speed: Horizontal layout, two offset single-acting pistons for constant force, large aluminum flywheel, low-friction Delrin cylinder. Machined on mill & lathe, with laser cutting and press fits; modeled volume & torque in Excel.
