Stuart Sirius Unmachined
Stuart Sirius Unmachined Set of Castings
The Stuart Sirius was originally designed for racing steam hydroplanes. Particular attention was given to the valve gear and steam passage design with the result that the engine produces great power using a surprisingly low volume of steam. Our tests have shown that running at 2800 rpm the engine produces 1/3 bhp. at 80 psi.
The Stuart Sirius is a very interesting model to build and can be completed on a 3 1/2 in. lathe. The kit includes a pair of finished gears, as these are difficult to produce even with specialist equipment. Please note that no materials are included in the kit.
Please remember our sets of castings require the use of a lathe and milling machine to turn them into a working steam engine.
