Buoyed by the success of my first attempt at building an engine and boiler I needed something a bit more ambitious. Again free plans from the internet for the engine

As it's marine engine it needed a marine boiler. The Scotch boiler looked interesting but I couldn't find and plans, so did my own.

I'll admit that the burner doesn't stay alight that we'll and occasionally 'pops' out. Not good for a boat so it never got near one. But if you want the plans they are attached below

Yes it's JP Duvals design. He does some great engines

I also have this video of its first run. I now realise how noisy it is, but in my defence it was one of my earlier efforts. I particularly like the speed control and how effective it is.
