00 Scale Locomotion No 1 Loco Scratch Aid

Designed by George Stephenson, Locomotion No. 1 remains an icon of the early railways.  Hauling the inaugural train on the Stockton & Darlington Railway of 1825 – the first public railway – it was a notable advance in locomotive design, notably through the use of coupling rods linking the wheels.  This model originated as a jumbo-ised N Gauge engine, suitably altered to 00 operative tolerances and to fit proprietary parts.  

Combined with the 00 scale Locomotion tender and component pack (each separately available; the pack includes bespoke ‘plug’ wheels), this scratch aid enables an unpowered free-rolling model engine that can be ‘motorised’ by coupling to a power source such as: https://www.shapeways.com/product/F9H5PPBEC/00-scale-open-truck-motorised  If a spoked version is wanted, the model can similarly accept 17mm diameter wheels (including flange; without c.16mm as per the Alan Gibson catalogue).  These will require a different return crank, however, a link to which can be provided if requested.

(Note: various materials are provided, however, WNV and BNV will require more preparation for smooth painting that FUD and FED.)

The following additional parts need to be sourced separately to complete (web links given as examples only):

Coupling rods (various lengths are available via Alan Gibson which could be adjusted or these can be scratchbuilt to suit).  
Loco-tender coupling
Styrene strip (for feed pump lever)
Wire (for piston rods and operational feed water pump linkages)
Pins (for rod linkages)

Optional additional details to add (at the builder's discretion):
