Mini Three-Legged Oscillating Single Cylinder Steam Engine Kit with Boiler
Hero Section: A Mechanical Jewel in the Palm of Your Hand
There is a unique charm to the "Swing" (Oscillating) steam engine. Unlike complex valve engines, this Mini Three-Legged model relies on the elegant dance of the cylinder itself to regulate steam. It is a masterpiece of minimalist engineering. Small enough to sit on your palm yet built with the precision of a Swiss watch, this engine captures the golden age of steam in a compact, glittering brass package. Whether you are a seasoned collector or looking for the perfect entry point into the world of live steam, this model offers a mesmerizing, rhythmic performance that you will never tire of watching.
Why Choose This "Swing" Engine?
This model is celebrated for its simplicity, reliability, and visual appeal.
- The Magic of Oscillation: The "Swing" design means the cylinder pivots back and forth to align with intake and exhaust ports. This visible movement adds a dynamic layer to the engine's operation that standard fixed-cylinder engines lack.
- Enhanced Inertia: We’ve upgraded the flywheel. By increasing its diameter and widening its thickness, the engine maintains better momentum. This results in a smoother, slower, and more consistent idle—the hallmark of a quality steam engine.
- CNC Brass Perfection: Mainly constructed from high-grade brass and processed via CNC machining, the surface is bright, delicate, and resistant to corrosion. It’s not just a machine; it’s a piece of desktop art.
- Ready-to-Run Kit: This isn't a puzzle; it’s a complete power plant. It comes with a matching boiler, a water injection port for easy refilling, and a base with pre-drilled mounting holes, making it easy to fix to a wooden plinth or a model boat.
Technical Highlights: The Expert’s View
- High-Torque Stroke: With a bore of 6mm and a stroke of 9mm, this engine is "under-square" (stroke is longer than bore). This design characteristic provides excellent torque, allowing the engine to overcome friction easily and run reliably at lower pressures.
- Three-Legged Stability: The unique tripod-style support structure ensures the engine remains stable during operation, minimizing vibration transfer to the base.
- Thermal Efficiency: The brass construction acts as an excellent thermal mass, preventing the cylinder from cooling down too quickly, which reduces condensation and ensures a "dryer," more efficient run.

Usage Scenario: The Desktop Ritual
Clear a space on your desk. Fill the boiler using the convenient injection port. Light the alcohol lamp and slide it under the brass tank. Watch as the water begins to boil. After about a minute, you see a wisp of steam. You give the heavy flywheel a gentle flick. The cylinder begins its hypnotic swinging dance—hiss-click-hiss-click. It’s a calming, analog experience that connects you to the history of mechanics, perfect for unwinding after a digital day.
Important Tips
- Lubrication is Key: Oscillating engines rely on the seal between the moving cylinder and the fixed port face. Apply a drop of high-viscosity steam oil to this interface before every run to prevent steam leakage and wear.
- Water Level: Fill the boiler to about 2/3 capacity. Overfilling can cause "priming" (water spraying out of the engine), while underfilling reduces run time.
- Safety: The brass components conduct heat very well. The entire unit will be hot during and after use. Handle by the base only or allow to cool completely.
