I thought it was about time I posted some of my stuff! This is a little steam loco I'm working on. I wanted to build a small live steam model and the old Mamod locos were always fun. I wanted to see how I could build my own rolling chassis with outside frames and try to get a loco that was far more scale than the little toy looking mamod loco!
It's based very loosely on a Kerr Stuart Sirdar 0-4-0 Tank Engine.
I've changed the dimensions a little to allow the use of 42mm copper tube as the boiler barrel and fitting of PPS Steam Models osscilating cylinders. I also added some crank weights to add something else to watch in the absence of valve gear!
The second image is a quick render of the 3d model of the loco which I've used to generate the toolpaths for cutting out the brass parts. The boiler in the background was a piece of 1 1/4" copper tube I used to practice my silver soldering on.
