Heh, you're the only one I've ever heard of doing this. I did see an Anime movie on youtube called "Steam Boy" but that was a ride-inside-the-wheel mono wheel thing...and a cartoon....and set in the late 1890's...did I tell you I'm making a steam punk gas tank from copper?
Really, most don't know what to think of this, I'm sure, but I think it sounds interesting. Hope we get photo updates
Check out myfordboy on youtube. He casts and machines scale 1 lunger motors, I'm sure some of what he does would apply.
