Working Pressure 45psi or 3bar
This engine has been engineered to give a balance between the aesthetic appearance and sound engineering practice. Miniature roller races have been utilised extensively throughout; in total there are twenty nine used for the crankshaft, valve shaft, reversing gears, big ends and little ends. The result being that the bottom end of the engine requires very little lubrication other than minimal lubrication for the eccentric straps. This lends itself very clean and smooth operation together with low maintenance.
In an effort to simulate materials of the age, the block, steam chest and engine bed have been manufactured from aluminium which is then treated to give a textured finish. The components are subsequently hard anodised to BS5599. Hard anodising has a hardness approximating "sapphire" and is therefore very durable and wear resistant. This combination gives a finish that closely resembles that of cast iron. Pistons and slide valves are manufactured from complimentary materials which offer extremely good sealing characteristics combined with very low friction.
Stainless steel, brass and bronze are used extensively throughout the engine. As a result of this the engine is light weight, compact and powerful, offering the modeller an engine that looks authentic and is highly functional which should give years of untroubled enjoyment.
