  • 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 twin cylinder Tandem mill engine is two single cylinder Mill engines connected via a large fly wheel on a steel plate and inlet manifolds, tee and elbow connectors. As such it is still relatively simple and retains the basic mechanics of engines which powered Mills and workshops and which needed the extra power provided by a twin cylinder engine.

    This Mill engine layout has two double acting cylinders, eccentric driven slide valves 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 each of the two crank shafts, two cast bases and a steel base plate.

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

    The cylinder assemblies and pistons are 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 and the steam inlet can be on the top or bottom of the chests.

    Included in the Tandem Twin kit are the brass inlet linking manifolds, which can be mounted on the top or bottom of the Chests, and steel base plate.

    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.
