Stirling Engine, Double-acting Steam Engine

Stirling Engines

A Stirling "coffee-cup" engine. Stirling Engines are
facinating devices that I find far more interesting
than steam as they are self-contained devices, using
more exotic materials, requiring much tighter
machining tolerances & are thus, harder to build.

Double-acting Steam Engines

A double-acting bronze steam engine machined from a rough castings kit.
Click on photo for a v
ideo showing the engine running on compressed air. A
mill & a lathe are needed for this project. A problem with kits is that they
minimize the amount of material per part making it harder to grip when
machining, possibly necessitating making a fixture, which in general is not
a beginner's project. The base is red oak with routered radius edges.
