Steam Engine Model Kit Vertical TwinCylinder CNC Machined Aluminum with Brass Gears and Precise Steam Timing

K007 oneway piston vertical steam engine Overview K007 is a oneway piston vertical steam engine designed for demonstration, bench testing, and model engineering. Steam is generated in a CNC machined aluminum vertical boiler and routed by a copper conduit into the main engine. Steam enters the cylinder through a ventilation valve to drive the piston. The piston crankshaft and ventilation valve crankshaft are gear linked to coordinate intake and exhaust. Key benefits Precise steam timing and smooth operation Gear linkage between the piston crankshaft and the ventilation valve ensures accurate control of intake and exhaust for consistent, repeatable motion. Durable, lowtolerance mechanical components Brass crankshaft with semicircular balance and precision brass gears with axial runout below 0.005 mm provide reliable, lowvibration power transfer. Improved heat to steam efficiency Conical combustion chamber in the vertical boiler maximizes heat absorption to speed steam generation and reduce fuel run time. Safer, more reliable operation Builtin safety valve relieves excess pressure automatically. A water level observation system reduces the risk of dry firing, increasing service life and reliability. Reduced assembly variance Integral CNC molded aluminum boiler minimizes dimensional error that can arise from multipart assemblies.
