  • DescriptionModel Engine

    All Chiltern Model Steam Engine kits are fully machined and can be easily assembled with basic tools. The model engines are fully working and can be run using live steam or simply using compressed air from foot or hand pumps.

    The horizontal single cylinder mill engine has a simple design, yet retains the basic mechanics of engines that powered many mills, factories and mine pits in the nineteenth century.

    The mill engine layout has a double acting cylinder, eccentric driven slide valve, slider and the large brass flywheel offers smooth running and is capable of powering a range of accessories, in a variety of roles. The engine also includes twin split bronze pedestal bearings for the crank shaft and cast base.

    The kit consists of precision produced parts each carefully made and checked to ensure reliability in service.

    The cylinder assembly, slider and piston are manufactured from brass and the piston shaft, Conn Rod and valve from stainless steel so are not susceptible to corrosion. The piston shaft passes through an adjustable gland and the steam inlet can be on the top or bottom of the chest.

    To power the engine with live steam, connect it to our Horizontal 3.5" Model Steam Boiler.

    In addition to the kit, subject to availability, a finished engine is available in black, red, green or blue. Please contact us for availability and pricing.
