|7 1/4" Gauge Bagnall|
0-4-0 Saddle Tank
These engines were made and supplied to customers all over the world and had to put up with indifferent fuels, drivers & climates. Therefore they had to be extremely rugged and easy to maintain, with a minimum of spare parts.
Our prototype was number 1842, built in 1907. It was one of a class of 18" gauge locomotives, and was supplied to Alfred Herbert Ltd. of Coventry. The only departures from the original design are the provision of an axle driven feed pump, and the use of Hackworth valve gear for its simplicity, although Bagnall Price valve gear can also be fitted.
The boiler is of the simple marine type, thus eliminating the need for a lot of complicated flanging of plates. It has been designed in accordance with BS 2790 to be of welded steel construction, and is a very free steamer.
All of the castings including the cylinders are fully cored wherever possible thus saving builders a great deal of difficult machining, and ensuring even steam distribution.
It is just possible to build this engine on a 3 1/2" lathe (e.g. a Myford 7) but a larger one for some of the parts will make life easier. MJ provides a machining service if required.
To assist you to build a first class model with the minimum of trouble, a builders manual, giving a step-by-step guide on machining and construction is available for this locomotive.
