  • 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 vertical single cylinder Bottle engine is a simple design, mechanically similar to the horizontal mill engine. The differences being that the crank shaft is turned through 90° and the cylinder is vertically mounted which takes up less floor space than the Mill engine.

    The engine has a double acting cylinder, eccentric driven slide valve 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 a cast pillar and base.

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

    The cylinder assembly and piston is manufactured from brass and the piston shaft and valve from stainless steel so are not susceptible to corrosion. The piston shaft passes through an adjustable gland which is readily accessible.

    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.
