A real gem of a live steam launch for sale. At 55" in length and 11.5" wide she is a nice size and built with loving care to an extremely high standard. The detail is superb.
The lauch has a professional made boiler with a wonderful vertical twin steam engine with reverse. The detail in the engine is also excellent and nice to have this engine as opposed to an oscillating engine.
This is a scratch built model by a surberb model builder who has also built a paddle steamer and two beautiful Thames barges. These other models are also available.
Seekadett 'Marten Howes & Baylis' boiler. Confirmed by Brian Marten.
NOTES FROM THE BUILDER
In this boat the water is carried in the boiler. There is plenty to drive the boat weighing 27 pounds at walking pace for 25 minutes.
The gas tank is really two parallel tanks joined by pipes to give a low profile to fit into the limited head-room. The tank has two electric heating coils that are powered by a 1200 mAh NiCad, the heater being controlled by a thermistor-operated switch. This is sufficient for a 25 minute run in winter. The gas, at steady pressure, is supplied to the burner through a burner-control valve that operates in response to a thermistor in the boiler to control the boiler pressure by turning down the burner to simmer. What we have is one boiler, powered by electricity, evaporating butane/propane mix that is supplied to the burner of a steam boiler to evaporate water to drive a steam engine. Both boilers are automatically controlled.
Steam is supplied to a two-cylinder engine through a throttling valve to control speed. The exhaust steam, which is wet and oily, goes into the first separating tank where most of the oil and water are separated and retained. The exhaust steam with the remaining oil goes into second separator where more water is collected and then to a discharge pipe in the chimney and to atmosphere as steam. The exhaust pipe in the chimney is about half way up so that it induces a flow of air through the burner to aid combustion.
