Thanks chaps, I'm in Gillingham, so about an hour from you Martin, your hospitality is welcomed and may just be taken up on; thank you.
Howard; I'd heard the same about the rigidity of the VS, but as you say I think it's a matter of going gently. However this is the reason I was favouring the 10H; smaller bed to machine.
Nige, thats excellent news; I suspect it will be the 10H I go for. I like the look of the 10V but prefer a horizontal. Maybe when I make a steam launch I'll make a vertical setup.
Speedy Builder; the intention in the longer run is to make a boiler as well; my grandfather was a boiler maker/inspector among other things so have some great advice to draw from there. I like the idea of a cornish/lancashire style. All part of the fun is the drama of building up steam. To start with however I'll see about running on compressed air. I can run an engine without a boiler, but a boiler on its own may be a little redundant! I'm enjoying the process of researching it. I'd like to make a boiler that is suitable for any future models I may make; this means I may end up making something a little over the top for my first model but that future proofs me for things I make later.
My eventual goal would be to make something along the lines of a scale Foden overtype steam wagon, but I still haven't decided yet. I've got a long time before I need to decide…
Thanks for the warm welcome, and the advice is gratefully received.
