Catalogue entries


2-inch Bore, 3-inch Stroke, 150 c.c., Speed 900 r.p.m., 23 b.h.p.

This Engine is for the man who wishes to build an Engine of the simplest type and cannot spend a great deal of time and money in doing so.

The Crankshaft, Con-Rod, Bearings, etc., can be made of plain bar material, but Piston Rings and Valves are supplied with the Castings – they are the work of the specialist. One piece of machining we do in every set of castings – the facing and boring of the bed to take the cylinder. It is easily and accurately done on our machine tools, but is extremely difficult in the average amateur's workshop.

The "Sandhurst" has no governor, no "frills". it is thoroughly practical and is meant for serious work under load – i.e. driving dynamo or pump. at 900 r.p.m. drives a 250-watt dynamo.

The cylinder liner is floating, sealed by a rubber ring. The cylinder head is not water cooled; unnecessary in an engine of this size. Ignition can be by coil or magneto, we advise the latter.
