JE Howell Model Engine Plans

Welcome to the world's largest catalog of quality plans for model Stirling engines, atmospheric engines, gas engines and other model engineering projects.

All plan projects are machined by you from your own metal bar stock. No castings are required, however, most of the model engines are designed to look like they were in fact made from castings. The plan set drawings are high quality computer generated using professional CAD software and are laser-printed on 8-1/2" x 11" paper.
