Live Steam 
Single Cylinder "Marine" Model Steam Engine 
SHORT VERSION 
Fully Machined Kit in Brass, Bronze & Steel 

The single cylinder "marine" engine is a simple design, yet retains the basic mechanics of engines which powered boats, farm equipment, and workshops in the nineteenth century.

To accommodate more confined spaces, e.g. in a boat, this version is 15mm shorter (height) than the standard version of the engine, otherwise identical.

NOTE: Pictures are of the assembled model (unpainted/unpolished), this listing is for the kit of parts (the final picture is of the standard version's parts). The optional second flywheel includes a slightly longer crankshaft.

The marine engine layout has a double acting cylinder, eccentric driven piston valve and the brass flywheel offers smooth running and is capable of powering a range of accessories, in a variety of roles. The engine also includes double split bronze pedestal bearings for the crank shaft, tube slider and a substantial cast base.

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

The cylinder assembly and piston are manufactured from brass and the piston shaft, connecting rod, column screws 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 front or back of the chest.

The kit consists of a set of fully machined parts that can easily be assembled using simple tools such as a screw driver, allen keys, pliers and metal file. The parts are mainly unfinished metal and will also require painting, polishing, filing, etc. to achieve the appearance shown in the pictures.

NOTE: The kit is supplied with socket or hex head set screws, although some screws for ease of installation, have to be socket head screws. Some screws as provided may need to the cut or filed to length to complete the model, contact us if this will cause a problem..

When assembled the engine is fully working and can be run using steam or simply using compressed air e.g. from hand or foot pumps.

To power the engine with live steam, connect it to one of our Model Steam Boilers.
