1901 to work the narrow gauge mainline over wooden
viaducts between the North Devon Clay Company
works at Peters Marland and Torrington. Avonside
is distinctive in having a wheelbase noticeably
disproportionate to its driving wheel diameter.
Maintaining daylight under the boiler and
a clear cab on this model proved quite a challenge.
A Nigel Lawton 10 x 12 motor and belt drive proved
to be the solution. The motor fitted within the
white metal boiler and the belt drive within the
firebox. The first chassis was cast in white metal
and whilst it ran well the design did not faclitate
simple belt changing and was replaced with a folded
etch chassis. The wheels I turned and pressed
in nylon centres to provide the required isolation
to the coupling rods.
