  • 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 model single cylinder Beam engine, though simplified, has all the basic elements of Beam engines which were widely used by industry in the early part of the industrial revolution. These, often huge engines, were used for pumping water from mines and extensively operated in many heavy industries.

    The Beam engine's Watts parallel motion, eccentric driven valve mechanism and large steel flywheel make this engine fascinating to watch, particularly at slow speeds.

    The engine includes twin split bronze pedestal bearings for the crank shaft and Beam shaft, split bronze Connecting rod bearings, cast steel column and substantial cast steel base.

    The cylinder assembly, chest, inlet/outlet pipes, eccentric rod, and piston are manufactured from brass and the piston shaft, valve, valve mechanism, connecting rod and parallel motion links from stainless steel so are not susceptible to corrosion. The piston shaft passes through an adjustable gland.

    All required Hex head setscrews are included in the kit. NOTE some setscrews will need to be cut/filed to length to complete the model.

    Each part in The kit is carefully precision made and checked to ensure reliability in service.

    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 can be produced to order. Please contact us for availability and pricing.
