L-S Loc Mini-Rocket

date ?






This is a small scale (HO) live steam model of Stephenson's Rocket. It is unusual in that it is mostly gold plated (typical of L-S Loc models).

The boiler is a simple pot boiler, 13mm diameter x 24mm long. It is fired by a single wick meths burner. The meths tank is mounted on the tender, connected to the wick holder by a length of flexible tubing filled with wick material. The meths tank is higher than the wick holder so the meths flow is a drip feed, regulated by a screw valve.

Steam is fed via two separate short pipes to the backs of the two port faces of the oscillating cylinders. The cylinders are single acting, 3.1mm bore x 7.5mm stroke, connected directly to crank pins on the two front wheels. Exhaust is direct to the atmosphere from the backs of the port faces, not even through the completely dummy exhaust pipes and chimney.

The engine is weighted by a block of heavy metal, probably lead, on order to lower the centre of gravity and increase traction.

Many of the main parts are made from cast brass, plated with gold (presumably only a thin plating!) There is, therefore, little corrosion, but there is some soot deposit from the meths burner.
