A 7 1/4 inch narrow gauge two truck Shay, scaled up from the excellent design by Kozo Hiraoka, with considerable modification and much added detailing.
The work of a retired engineer, a professional welder who spent his working life with Murex, latterly ESAB. A man with equal facility in design, machining, fabrication and sheet metalwork, his wide-ranging interests have seen completion of a 4 inch scale traction engine, replica AC Cobra, radically re-worked Morris Minor pickup with heavily-breathed on two litre engine, model internal combustion engines - including a beautiful Westbury Sealion on his bench when we visited - and, his latest project, a one quarter scale model of his Bridgeport milling machine, fabricated without the use of castings and being built to exhibition quality.
Initially built with plain axlebox and drive shaft bearings, these were deemed to create too much rolling resistance so were replace with roller bearings. The crankshaft runs in four bronze bearings fed by wick oilers housed in an oil trough in the cab.
The engine has effective steam brakes and is fitted for train vacuum, with a combined steam/vacuum brake valve. The ejector works efficiently, pulling 15 inches of vacuum reliably.
The boiler has had hydraulic and steam tests with new certification issued - the engine comes with club boiler history back to the first test when built. Water feed is by injector, hand and mechanical pumps - the injector is a delight to use, reliable in operation and picking up instantly.
Draincocks are steam-operated, with a lever in the cab, the ashpan and heavy duty grate are in stainless steel. A dummy toobox on the offside running board houses a large capacity lubricator, as well as a battery for the headlamp, switchable from the cab.
There is a snifting valve mounted on the main steam pipe from the dome which works effectively, closing with a satisfying "pop" as the valve chest pressure rises on setting off.
Offered complete with firing irons, starter kit of coal, oil and water treatment, with 12 months warranty. We would be more than happy to give half a day's instruction on the steaming, running and disposal of the engine to a new owner if required (any excuse to have another run with it ourselves, to be honest...)
