This single-cylinder vertical oscillating steam engine was built by Les Cade. The engine was built from a bronze casting kit using Sherline miniature machine tools. An oscillating cylinder steam engine is a simple arrangement that does not require valves to direct steam in and out of the cylinder. Instead of valves, the entire cylinder rocks, or oscillates, such that one or more holes in the cylinder line up with holes in a fixed port face or in the pivot mounting (trunnion). Engines of this type with one or more cylinders were often used in early marine applications. The brass engine has a 1.75″ flywheel.
