CK #1


This delightful little engine is minimalism in the extreme. It's a simple oscillating cylinder mounted on the firebox along with the crankshaft and with a base that barely exceeds the firebox in size. It is made mostly of brass, the exceptions being the burner, flywheel and crankshaft. No part of it is painted.

When I acquired this engine, I was led to believe it was an imported Crescent model. However, I was later able to confirm that it has "CK Foreign" stamped almost illegibly on the base so it is, in fact a CK brand.

The galvanised steel meths burner has two wicks and a handle, which doubles, potentially dangerously, as a filler and vent. The boiler - 38mm diameter x 85mm long - has a safety valve and no other fittings. The steam pipe feeds from one end of the boiler to the engine frame, which is a thin brass bar riveted to the side of the firebox.

The single cylinder is a basic single acting oscillating type, 6.8mm bore x 23mm stroke. The crankshaft penetrates through the firebox and has a 36mm diameter lead flywheel on the other end.
