Hi Folks. I was a member on this forum quite some time ago, but didn't post a lot. I am a retired design engineer, and have been designing/building model steam and i.c. engines for about six years now. I have successfully built and ran seven steam engines and seven i.c. engines, and am currently designing a 1" bore side valve gasoline engine that can (hopefully) be built from bar stock. I hope to be a good contributing member to the forum.---Brian Rupnow
