Model LS313S Marine Two Cylinder Reciprocating Steam Engine Model Kit Overview A precision metal steam engine model made of copper, designed for adults and advanced hobbyists. This compact, working model is suitable for physics experiments, mechanical demonstrations, and collectible display. Recommended for ages 16 and older. Key benefits Working mechanical model: Operates under controlled steam or compressed air pressure for handson demonstration of reciprocating engine principles. Durable, precise construction: Precision cast base with electrophoresis surface treatment resists corrosion and provides a refined appearance. CNC machined components ensure accurate fit and reliable operation. Stable and long lasting: Ladder frame structure increases torsional resistance. hardness beryllium copper spindle bearings and a 0.08 mm red copper cylinder head seal improve durability and thermal resistance. Easy maintenance: Piston connecting rod includes a lubrication filling port so all friction surfaces can be regularly oiled to prolong service life. Compact and displayready: Small footprint and refined styling make it suitable for desktop display or inclusion in a mechanical model collection.
