Illustration No. 3 is the last model I built, being an attempt to reproduce, in miniature, the new “K” class locomotive, K900. The gauge is 1 ¼ inches, the mechanism being electric {eight volts). As I had a spare 6-wheel electric chassis in my workshop I decided to utilise this in the building of the model, adding two additional wheels, specially cast from the originals, thus making it into an eight-wheeled; chassis. I took the mechanism page break page 43 to pieces, and made two new frames between which the motor was fitted. To enable the engine to take the corners easily, I turned off the flanges of the two back wheels. The cylinders being the next job, I made a wooden pattern and had two cylinders cast in aluminium. The cylinder covers were made of brass and turned and screwed into the aluminium. They were then bolted to the main frames. The next job was to make the front and rear bogies. As the front bogies of the “K” class locomotives have S.K.F. bearings, with outside bearings, I had to build up the frames to imitate, as near as possible, the real article. The leading wheels of the rear bogie are smaller than the trailing wheels. The axle boxes were made in white metal castings riveted to the trailing frame.
