Part built Gauge 1 GWR Saint class loco, the engine is driven by a 12v dc motor with integral gearbox which will be radio controlled with battery pack and receiver in the tender. The model is entirely built including the wheels using a CNC milling machine.

Hi Mike,
That's a really sharp looking engine you've built there!
So, for us Gauge challenged folks, what would Gauge 1 translate to in scale? 1" to the foot? Or something completely different.
Thanks,
Kim

Hi Kim, Gauge 1 is 45mm or 1 3/4 inches. There are various scales that apply depending on the gauge of the 'full size' locos gauge. By way of example, standard gauge, 1435mm or 56.5 inches divided by 45mm or 1.75 inches gives us a scale of 1:32 (approx). Similarly, 36 inch or 915mm (approx) gauge gives us a scale of 1:20 (approx). Generally speaking scaling narrow gauge engines results in a larger model. Sometimes models that are very small i.e.. Asters Lion is modelled at a slightly different scale to make it a little larger, in this case 1:30. Regards Paul Gough.

Thanks for the Gauge vs. Scale primmer, Paul. That rings a bell - I'm pretty sure someone's explained that to me before. But even with my ill formed question, you answered it! Gauge 1 is 1 3/4". Trains have their own multi-dimensional complications, don't they? :)
Thanks,
Kim

Fresh out of Swindon A shop! almost complete Saint, the cab details and backhead left to finish the job.

Lovely work Mike, I would not know where to start doing that on a mill! Regards Terry

That's a lovely loco!

Thanks for kind comments, will post more pics when engine is completed.

The Saint is finished, and I am rather pleased with it. It was more complicated than other engines I have built, in that clearances between moving parts is minimal therefore the build up process has to be done in order as otherwise access is not possible, but it turns over nicely, there is a slight squeak per revolution that could almost be the slap of the vacuum pump!!!

Wow - very nicely done!!

Fantastic Mike. amazing details too, especially in the cab.

beautiful finish and paint, and CNC does not help for that ! Scale appearance of this loco is impressive.
Congratulations.
Painting on brass sheet needs lot of skill. I am far from getting this level of painting of my locos alas, gauge 1 too and also 16mm, but live steamers.

Thanks for your kind comments, regarding painting models I use scouring powder (pumice) with an old tooth brush to remove any traces of flux and abrade the surface, then gray primmer (spray can) followed by two coats of colour applied with a basic air brush then left in the boiler room for two days to harden.
