          Pretty exciting. It would be good to have an idea of the rpm. Also the design of the turbine. Sorry if you have posted details before and I missed them. A lot of fun, as you say.

            Thanks Simon, I forgot to take pics as I built it, just got too immersed.

            Its pretty simple inside, I made the vanes out of quite thick copper sheet and they are very heavily silver brazed into place on the brass section to with stand the force on them. I think I might have to invest in one of those el cheapo digital tachometers on eBay as I would like to know the rpm's.
            Hooked it up a little while ago to a small DIY genny and it lit up a gang of light bulbs without a problem.

              Did you see the recent series on turbines in ME? It was very detailed and would be a good guide for better efficiency. A turbine for say, a loco headlight, eg, DHR B, would want to be thrifty on steam. But if yours is just for fun, it doesn't matter.

                No unfortunately I didn't Simon.
                Its been ridiculously hot since I finished this and have had only limited time in my shed. I did hook it up to a DIY genny and it lit a bank of globes very easily. There's a fair bit of internal centrifugal weight when its up and spinning, but it won't have the same grunt as a steam engine.
