7 1/4 inch narrow gauge petrol mechanical shunter

An 7 1/4 inch "minimal gauge" style shunter, comprising a rolling chassis with takeup bearing axleboxes and spoked iron wheels, the axles fitted with chain sprockets.

The Honda overhead cam engine, sourced from a "Supercub" style step-through motorcycle, features automatic transmission and centrifugal clutch.

Of robust construction, it already weighs over two hundredweight - fitted with a set of 3mm laser cut steel bodywork we could see it tipping the scales at twice that when finished.
