New Vertical Twin cylinder "marine" 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 second version of the vertical twin cylinder marine engine is basically two single cylinder marine engines connected via a common crank shaft. As such it is still relatively simple and retains the basic mechanics of engines which powered larger boats and other applications which needed the extra power provided by a twin cylinder engine.
This marine engine layout has two double acting cylinders, eccentric driven slide valves, tube slider, and a brass flywheel offers smooth running and is capable of powering a range of accessories, in a variety of roles. The engine also includes triple split bronze pedestal bearings for the crank shaft, steel top plate, eight columns and cast base.
On the twin crankshaft, 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 assembly and piston is manufactured from brass and the piston shaft, valve and column screws from stainless steel so are not susceptible to corrosion. The piston shafts pass through an adjustable gland.
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.
