Thanks for the introduction, and welcome to the fold! I built a 531 bike frame back in 1978. I won a road race on it the following year, and the rather sad-looking frame is still hanging up in my garage, rusty, cracked and with a stuffed bottom bracket shell. Can't bear to throw it away…
Good luck with your steam project. Tubal Cain, aka Tom Walshaw, published a couple of books on "simple steam engines" and they're well worth acquiring for the gems they contain as to how to go about it. I built his steam crane "Hercules" for my nephew and it was a very interesting project.
