Working tabletop heat engine model built for reliable demonstration and long term display Key benefits and why you need it Demonstrates real heat to motion conversion with durable components, making it suitable for education, hobby projects, and engineering displays. Solves common model engine issues such as poor rotation and rapid wear by using precision bearings and metal parts that resist deformation under heat and load. Stands out through materials and craftsmanship that combine visual appeal with functional performance. Main features and performance construction: solid hardwood baseplate, finely polished for a smooth, stable platform that resists warping and enhances presentation. Elegant bracket design: hollowed and visually detailed metal bracket provides structural support while creating a refined, collectible appearance. Smooth operation: imported precision bearings enable lowfriction rotation; the machined silver flywheel maintains momentum for steady, predictable motion. mechanical components: pure copper crankshaft for reliable torque transfer, stainless steel cylinders, valve baffles, and connecting rods engineered for consistent operation and longer service life. Heat source and fuel handling: included metal alcohol lamp with heatresistant wick delivers controlled heat for repeatable demonstrations and experiments. Improved conversion efficiency: combination of precision bearings, machined flywheel, and sturdy crank assembly enhances mechanical conversion and reduces energy losses during operation. Materials and compatibility Baseplate material: hard solid wood, polished finish. Structural and moving parts: metal bracket, machined flywheel, pure copper crankshaft, stainless steel cylinders, valve baffles, and connecting rods. Heat components: metal alcohol lamp and heatresistant wick designed for sustained use with liquid alcohol fuel. Compatibility: designed for tabletop demonstrations, educational setups, hobbyist collections, and small exhibit displays that require a compact, working engine model. Practical use scenarios Classroom demonstration: show principles of thermodynamics and mechanical conversion in physics or engineering lessons using a visible, working model that students can observe and measure. Hobby and display: integrate into a desktop collection or workshop bench to illustrate mechanical motion and craftsmanship while serving as a handson conversation piece. Science fair or workshop prototype: use the model to validate basic design concepts, demonstrate efficiency improvements, or compare the effects of different heat inputs and loads. Care and handling Operate on a stable, heatresistant surface and allow components to cool before handling. Use recommended liquid alcohol fuel with the provided metal lamp and maintain the wick to ensure consistent flame and heat output. Periodic light lubrication of bearings and crankshaft will help maintain smooth rotation and extend component life. This working engine model combines materials and precise machining to deliver a dependable, visually appealing demonstration of heat driven mechanical motion.
