Owl Castings UK

Over the last decade Owl Castings have become one of the UK’s largest producer of full size and scale model castings for live steam locomotives and traction engines. We have cast every possible casting that would be used to build live steam traction engines and locomotives in both ferrous and non-ferrous metals. Our metal castings span brass, bronze and iron, we even work in aluminium. We regularly cast metal components for all scales of live steam locomotives including, 2.5”, 3.5”, 4.75”, 5”, 7.25” and 10.25” also including 45mm narrow gauges.

Steam Powered Model Helicopter Project


A project to make a non-flying model Helicopter powered with a steam engine with a flash boiler

This has been an ongoing project with very little time spent on it - I reassembled the heli to make this video clip and ran the engine on compressed air for ease.

The engine is a single cylinder double action wobbler and will turn the rotors at 10psi and has a surprising amount of torque on start up. I have not had the pressure above 25psi with the rotors engaged but the engine has been tested at 90psi. .... More details and Plans for the Steam Powered Helicopter here

Ayesha - 2 1/2" 4-4-2 Live Steam Locomotive Plans by LBSC

"LBSC" was the pen-name of one of model engineering's most prolific writers. Lillian "Curly" Lawrence was born in 1882 and died in 1967.

Ayesha (The name Ayesha comes from a character in "She", a novel by H. Rider Haggard) is one of the more famous model locomotives by LBSC and was used in a challenge to prove that the 2 1/2" scale Live Steam Locomotives where capable of pulling human passengers. LBSC designed a boiler for his model and set out to prove the point.

Ayesha Plans Ayesha Model Ayesha Plans

The PDF Plan Set Consists of

4 Drawings sized 11.69" x 24.8"

2 Drawings sized 16.53" x 23.39"

3 Drawings sized 11.69" x 16.53"

All parts are detailed including safety valves and boiler valves - the plans are a complete set guiding you to produce a vintage 2 1/2" gauge Steam Locomotive capable of pulling passengers.

The plans assume that the builder has access to normal workshop tools.

This plans set is for experienced model engine builders although a novice builder would be capable of building this engine.

Home made Steam Engine Boilers should be tested before use. It is very important to use Silver Solder or Brazing Alloy for all joints on a model Live Steam Boiler.

Normal Lead/Tin solder is not suitable for the considerable pressure created in a Model Steam Engine Boiler.

Model Steam Engine Boilers can be fired with Alcohol, solid fuel tablets, wood or even coal. Consideration must be given to which fuel type is to be used when choosing the free boiler plans.
