Wilesco D2


At the time of writing, this charming little engine is Wilesco's smallest and cheapest, but is made to a higher standard of quality than most of their models. I'm not sure if it is actually made by Wilesco or if they have branded a model made by someone else. It is a tiny overtype engine mounted directly on the top of the boiler, which is supported by a tripod over a candle for heating.

The candle is a T-light sized candle in a glass container. The candle supplied is made from beeswax which, I'm told, burns with a hotter flame than the usual paraffin wax. It also has a larger diameter wick which gives a larger flame than the standard T-lights.

The boiler is supported over the candle by a tri-pod arrangement. It is a squat vertical cylindrical pot boiler, 45mm diameter x 30mm high. Apart from the engine itself, the only fitting on the boiler is a filler plug. There is no safety valve or water level indication.

The engine itself is mounted directly on top of the boiler with no pipework. The cylinder is a simple single-acting oscillating cylinder; 5mm bore x 7.5mm stroke. The crankshaft has a disk type crank on one end and a 30mm diameter machined brass flywheel at the other. The centre of the crankshaft appears to be running in a miniature ball race.
