ThermoForge™ Buildable Stirling Engine

ThermoForge™ makes thermodynamics tangible. Its exposed flywheel, connecting rods, cylinders, cooling fins, and crank mechanism let you follow every stage of the engine's movement instead of hiding it behind a casing.

The QX6 arrives as a reusable assembly kit, giving curious builders the satisfaction of constructing a functional mechanical model before operating and displaying it.

Features

• Working single-cylinder Stirling engine model
• Buildable and reusable all-metal construction
• Large three-spoke flywheel
• Exposed crank and connecting-rod mechanism
• Finned cylinder sleeve for heat dissipation
• Integrated alcohol-burner tray and wick
• Included assembly tools and fuel bottle
• Designed for ages 14 and older

Approximate Dimensions

• Length: 160 mm / 6.30 in
• Depth: 60 mm / 2.36 in
• Height: 60 mm / 2.36 in

How It Operates

1. Assemble the model and place it on a level, heat-resistant surface.
2. Check that the flywheel, linkages, and piston move smoothly.
3. Add high-purity alcohol to the burner.
4. Light the wick and heat the hot cylinder for approximately 20 seconds.
5. Gently turn the flywheel to start the cycle.
6. Extinguish the flame after use and allow the engine to cool completely.

Safety

• Adult supervision is required.
• Recommended for ages 14 and older.
• The flame and metal cylinder become extremely hot.
• Use only on a stable, nonflammable surface in a ventilated area.
• Keep fuel sealed and away from heat when not in use.
• Never add fuel while the burner is lit or hot.
• Allow the model to cool fully before touching or storing it.
• Contains small parts and is not suitable for young children.
