3 1/2" Steam Locomotive
Lumi requested that I post about this ongoing project of mine. I am currently about half way through builing a working 3 1/2" gauge live steam locomotive. This is built from plans, castings for the wheels and cylinders and various metals (steel, bronze, brass etc). This project is why I have not been building robots lately.
I originally bought my lathe as a way of adapting wheels and axles for robots, but somehow have never used it for that purpose! I had no previous Model Engineering at the time. I initially built a simple oscillator engine and since that worked first time have now started the Northumbrian as my next project. Luckily I am a draftsman by trade (though in Town Planning) so can at least read plans. I am totally self taught in regards all of the machining.
Rather than duplicate too much here it is probably best to follow my build log on MECH via the link. This shows all stages of my adventure in building this locomotive, including the mistakes. I will update here on major milestones - the next of which is the running on air, hopefully around Christmas.
Just to give an idea of size, the locomotive is around a foot long (300mm), excluding tender, yet should be powerful enough to haul my substantial corpus around the club track. I have been working on this locomotive since November 2011.
MAJOR UPDATE - yep I'm shouting. Chassis now running on air - see link http://youtu.be/7vVmGzOczFM
