I designed this engine to avoid using any machined components. It uses a laser cut & 3D printed components, as well as a graphite piston/glass cylinder from air-pot.
I used a bell crank mechanism to allow the power piston and displacer to share a single crank pin.

Fantastic work, looks like it runs great. Any pics of components?
