We have experienced a great demand for a highly efficient and powerful engine, on the lines of our world-famed winner of races - the "SIMPLEX" , yet smaller and suitable for boats built on the fine lines up to 3-ft. Long, and requiring a fair turn of speed.

The extraordinary success of our S.T. Twin Oscillating Engine has encouraged us to produce the "METEOR", which we feel certain will shortly find a place in the hearts of all lovers of Model Engines, with others of the "STUART" range.
We are enabled, by modern methods, to market this engine at the extremely low price of

18s. 6d.
Including our No. 155 Displacement Lubricator and Stop Valve, the price of which alone is 5/-.

Design

Another small marine engine of the 4 column type.This small engine has one of the simplest cylinder designs stuart has made. A simple extrusion with an egg shaped profile, made from a hard brass, the extrusion process hardens the brass even more. 2 holes are drilled down the extrusion for the cylinder bore and piston valve. a hole is drilled in the side for the steam inlet/ outlet. a few holes to fix the top and bottom cover and the cylinder is finished. A simple piston valve is fitted requireing close machining tolerances and plenty of lubrication via the specially designed displacement lubricator combined with stop valve. A simple round trunk guide for the easily machined crosshead. a single piece eccentric strap/ rod. A disc crank and simple shaft. Machined in bearings cast in the soleplate. Add a simple cast iron base and a small marine type flywheel with added prongs to engage in a propellor shaft A very simple engine. Boy does it run fast. The video and picture below are of my example, running on 20 psi, up the pressure and it will fly. A special double barreled boiler was created for use with this engine shown in the title bar above.
