Hi Eric, congratulations, it’s running really well.  It is an entrancing motion.

Timing the valve would be interesting to get your head around.

Thanks for all the comments! I had a good time building it and I learned a few lessons in the process. I'm already starting to think it looks fine the way it is, but I'm still going to clean some things up before I call is finished.

I think the valve timing is like most other steam engines. The valve is at full travel when the crank is 90 degrees from the piston rod. Just had to play around to find that point.

As for being and addiction, I think that ship has sailed! I was hooked the first time a made a part on a lathe.

Eric, If I understand correctly that this is your first engine effort, then I am very much impressed. A beauty and a good runner!   --Tim

Well it took me almost 5 months but I finally made replacement nuts for the steam connection. Now I'm happy with how it looks.
