David, Thanks for the welcome. I'm firmly in the tinkering class, so far having built a 10V, some Hemingway kits and various workshop aids such as Harold Hall's grinding rest. I've had an ML10 for 40 odd years, but haven't ventured into building anything of any significant complexity in that time. But what I do do gives me a lot of pleasure, and as far as I'm concerned that's what it's all about!
