1 inch 'square' engine

I call this engine my Square engine because its 1 inch bore and stroke and because its.... Square. Its dated 1952 on one side.

Its a flash steam hydroplane engine, with a piston valve for inlet and again a uniflow exhaust. Its also ballraced, and has a fully adjustable eccentric driving the inlet valve. I intend to have this engine in a boat and racing in the A/S class for the 2015 season.

Bassett Lowke Uniflow poppet valve engine

It is beautifully made, and relies on a crankshaft driven cam to actuate the inlet poppet valve. Its another uniflow design. The cam has slipped on the shaft so it currently doesnt run. I need to work out how to adjust the timing, the cam is hidden between two ballraces in the main casting.

It dates from around the early fifties. Heres an ad i found in a 1952 edition of ME–

3 cylinder valveless engine

This is my favourite engine. Its big, and wierd, and sounds like a spitfire when its running. I have no idea who made it, it is unsigned.

It has three cylinders of 1 inch bore and stroke and a grand total of 12 moving parts, and roughly two dozen parts to the engine as a whole. It works by covering and uncovering ports in the spigots at the tops of the cylinder heads. Its also a uniflow design. It is brutally powerful, and did i mention it sounds like a spitfire?
