Hey guys,
Flushed with my success with the Stuart 7A, I am beginning on my next project.
This will be entirely scratch built from bar stock, except for the fly wheel which I am turning from an old bar bell.
Please take a look at the plans I have drawn so far and see if you can find any glaring errors that might make it explode when I first plug the air in.
The cylinder build will follow Jason's idea of milling the top flat and fitting the valve chest base with the steam passages already milled in.
If the plan looks familiar it's because it's basically a Muncaster simple horizontal; turned into a twin. Although being a twin required a lot of changes to the crank shaft.
Thanks again.
