Philcraft beam engine

As the maker, Phil Gravett, says, this is the flagship model of his range. It's certainly the most impressive looking and probably the most expensive. Not only is it unusual in being a beam engine, it is also the only one of the range that doesn't use the same oscillating cylinder as the Jenny Wren. It is mounted on a wooden base with cosmetic features like the bronze rope and engraved floor.

The boiler is similar to that used on the Lilliput - 46mm long x 22mm diameter. It has the same single flue arrangement for the chimney as the Lilliput. It has the safety valve fitted in the centre of the boiler, and a steam dome at one end. The burner is a 2 wick type, with unusual metallic wicks.

Steam is fed from the dome through a simple double loop superheater under the boiler, to a semi-rotative valve on the side of the cylinder. The cylinder is 8.75 mm outside diameter, so probably about 6 or 7mm bore. Stroke is 8mm. The piston rod is connected directly to one end of the beam with a slot to allow for misalignment due to the rotation of the beam. The beam is 32mm long between pivots, supported centrally on an ornate pillar. The far end of the beam is connected to a crankshaft by a 27.5mm rod. The crankshaft has an eccentric for the valve, immediately behind the main disk crank. On the other end is a 38mm diameter spoked flywheel. Exhaust steam is fed back to the chimney.

A version of this engine without a boiler and mounted under a glass dome can be found here. An interesting difference is that the configuration is a mirror image! I don't know if this was normal.
