I have always been fascinated by miniature steam engines and have wanted to build one since I first began metal working. For years I searched for a design that was esthetically pleasing and one that didn’t require a compressor. Recently I found this beautiful design by Jan Ridders<\/a>\u00a0who was kind enough to share his plans with me.<\/p>\n

This Stirling Engine uses neodymium magnets in the displacer and slide piston to control the return stroke of the displacer. A third magnet above the displacer balances the forces to minimize friction in the glass cylinder.<\/p>\n

All pistons are made of graphite, the main cylinder is a Pyrex test tube, the engine is machined in brass and aluminum, the base is Corian and the flame uses isopropyl alcohol.<\/p>\n
