I have buil models of the Ruston & Hornsby 48DS type in 2mm,4mm, 7mm, Gauge One and now Gauge 3. This is my first build of anything in this scale and it's hard work. The nickel silver sheet that the frames and brake components are made from is so thick and hard that I have had to abandon the usual methods of removing parts from the frets and resort to a hammer and chisel!

It will be driven by a large Mashima motor/Slaters gearbox that is usually fitted into large mainline type locos in O gauge, via delrin chains and sprockets to both axles. No means of mounting the power unit is provided in the kit, so I'm going to have to get creative and probably make some patterns for profile-milling.

And just to illustrate the size of this thing, here is one of my own builds, a K's 4mm scale Hunslet contractor's loco, sat on the frames of the Ruston.
