This is a very superb model! I have seen it a number of times. As I followed his build over the years , he would have it at the N.AM.E.S. shows, in the different stages of build. I need to find my pictures of the progress that he made over the years.

Brian,
I could use your help on the Lower Valve Lever-2 of the Larger Simple Beam Engine. I've included a BAD rendering of the lever but I'm sure you'll get the idea. I have no knowledge of CAD and do not have CNC on my machines. Everything is manual. Is it possible, after you see the rendering, for you to give me the dimensions of X and Y distances? It's a slow build for me as I've made a few mistakes and had to make parts over again.
Thanks,
Grasshopper

I can see a light at the end of the tunnel for this project. Some parts do have a little binding and I'd rather have that than sloppy loose. Binding can be lapped away. I'm getting ready to finish the air valve and my brain just can't get around something. Where are the exhaust ports supposed to be? Anyway, here are a couple of pics of my progress. Yes, I did make a plate for the front of the cylinder to keep most of the air where it should be. And I did make a mistake when I ordered the base plate. Ordered 3/8 instead of 5/8 thickness. But decided to work around this and so far I believe it will work.

There is a hole right at the base of the square cylinder. It goes from outside into the round hole that the valve rod slides in. The exhaust comes out there.
