NEW horizontal Twin cylinder "mill" 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 mill engine has a simple design but retains the basic mechanics of engines which powered many mills, factories and mine pits in the nineteenth century.
The Twin Cylinder mill engine layout has two double acting cylinders, eccentric driven slide valves and a brass flywheel and is capable of powering a large range of accessories, in a variety of roles. The engine also includes triple split bronze pedestal bearings for the crank shaft and a substantial cast base.
On the twin crank shaft, the cranks for each cylinder are offset by 90° which means the engine will self-start in any position.
The kit consists of precision produced parts each carefully made and checked to ensure reliability in service.
The cylinder assemblies, slider, inlet manifolds and pistons are manufactured from brass and the piston shafts, connecting rods and valves from stainless steel so are not susceptible to corrosion. The piston shafts pass through adjustable glands and the steam inlet can be on the top or bottom of the chests, left or right hand sides.
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.
The pictures are of the finished model after painting and polishing.
NOTE: The engine by default is now supplied with slot head screws. Socket Hex screws, as shown in the pictures, can be provided as a no cost option.
