I'm happy that I stumbled upon this site. I've been interested in model engineering and watchmaking for about 20 years, and saw some model steam launches and paddlewheelers at the Cabin Fever Expo in York, PA last year. I'm really interested in building a beam engine some day and a paddlewheer seems like a really elegant way to put it to work. I'm still in the research stage, but it looks like I've caught the bug. Thanks for making all of this information available. -Reid
