Sheet1 General Arrangement (Version 000)
In this "First Hit" you can see that the drawing is composed of those dimensions I have been able to determine in mumeric form. These include the axle centres, wheel diameters, boiler diameter, overall length and so on.As I'm sure you'll agree, it's not much.
Much of the background information for this locomotive has so far come from text, pictures and drawings in the late Brian Haresnape's book "Stroudley Locomotives". Haresnape himself suggests that his book is aimed at railway modellers, and I know I am indebted to him for capturing and presenting so many excellent pictures of this locomotive and it's family. Many of these locomotives aren't preserved, having even this level of detail available is a precious piece of history.
In order to get at some of the dimensions that make the locomotive appear correct, I'm going to have to take measurements from the line drawings that I have. Whilst this is not ideal, it's way better than guessing. To this end, I have made copies of some line drawings and scaled them up. To take measurements I have a vernier caliper, readings from which I can scale numerically with a calculator. Just as a reminder, Stroudley didn't even have one of those. I guess the best he had was a slide rule and a well drilled mind; ...the time that a calculator would have saved him!
At this stage I'm assuming that the buffer height is fairly standard, but the visual proportions will undoubtedly make their impact as the drawing develops.
