Mini V4 Steam Engine Model - Metal Physics Science Experiment For Adults

About This Product

For all you engineering enthusiasts and steam power fans, this mini V4 steam engine is seriously cool! Measuring just 9x8.5x7cm and weighing 180g, it's a perfectly detailed miniature that fits right in your hand but packs some impressive engineering. The metal construction feels solid and high-quality with a bright surface finish that shows off all the intricate details. This isn't just a display piece though - it's a fully functional model with four cylinders (8mm bore × 8mm stroke), 3mm axle, and Walschaerts valve gears that actually work at 2-4kg/cm² pressure. Now, important note - you'll need to provide your own boiler since that's not included, plus you'll need steam cylinder oil for lubrication and a φ4mm copper pipe to get it running. But once you've got it set up, watching this thing operate is absolutely mesmerizing. It's perfect for learning about steam engine principles, adding to your collection of mechanical models, or even incorporating into larger steam-powered projects like ships or generators. The precision engineering is impressive - you can see every moving part working in harmony. Recommended for ages 14 and up, it's that perfect blend of educational value and pure mechanical fascination. Whether you're a student learning about thermodynamics, a hobbyist who loves mechanical things, or just someone who appreciates finely crafted miniature engineering, this V4 steam engine delivers both beauty and function in one compact package.
