I cant remember the last time I had this much fun with a
steam wagon, in any scale.
A four inch scale wagon, freelance construction underneath
but worked up to resemble a Sentinel on the outside. Its by no means an
exhibition piece, however the ingenuity of engineering in its construction and
the sheer driveability of the thing are remarkable.
Steel vertical boiler with expanded tubes, working pressure
175psi. Feed by twin crosshead pumps, backed up by a substantial
double-acting hand pump. Nabic safety valve.
Engine is constructed around a substantial pair of
locomotive-type slide valve cylinders in cast iron, driving an overhung crankshaft.
Drive by chain to an Albion three speed gearbox
more usually seen in ancient British motorbikes then by another chain to
the rear axle. Given the engine has a reverser, this gives three speeds both
forward and backwards, which is quite entertaining.
The engine steams freely and pulls well the previous
owner recently completed a twelve mile road run with it, which from my own
experience seems not only feasible but likely to be enjoyable. The wagon is
fitted with a powerful hydraulic foot brake, the regulator is coupled up to a
matching pedal on the other side (although you need to remember its brake on
the right, accelerator on the left, not like your car).

I rather like the way your legs hang out the bottom, Fred Flintstone-style.
