I am a new member of Paddleducks and would like to introduce myself. My passion is in live steam engines, I have just recently designed and completed a single cylinder double acting self starting oscillating steam engine. This engine has a 3/8" bore and a 3/4" stroke. The engine runs very well and will self start every time. I have built a open Launch boat that I scaled up from the Midwest launch plans to a length of 26" this engine moves the boat along very well. I will post some pictures in the near future. I also have interests in live steam locomotives and am currently designing and building a live steam logging ( climax) style locomotive in 7/8" scale that will run on gauge 1 track. I have been active in this hobby for many years and have built quite a few live steam engines and boilers.
