The sun has been out this week so not much got done on the Bernay. I did complete the Eccentric and the eccentric strap. The original plan did not have a shaft coupler so I added one because an engine needs a way to transmit its power. My phone was dead this morning so I used a different camera and the photos are poor, sorry about that. A week of rain just started so I should complete the the valve linkages soon.

Shaft coupler? Could you explain that? I can thimpfk of two or three things that might be.
 
Here are the valve linkages. This project is almost complete now. Next up will be the valves and a board for the base. After that I will make the steam manifold and then make a video. The end is near, always a sad day.

Normally I have a new project lined up but not this time. I have a lot on my plate this spring so it will be summer before I have to decide.

With your skills you can do anything. May I suggest a couple of really strange engines?
 
That is a sight to behold, i’ll Be waiting on the video.
Makes the small engines i build look kind of pedestrian:)
I know what you mean about the full plate.
I’m in the middle of a project, but the only machining/welding I’ll do until fall will be on tractors/implements.
So it goes.......

This Cross-Twin has me intrigued: I have it in my "Elmer's" folder, so it must be one of "Elmer's". I'll look for another you might be interested in.

There's another called a "Fuelless" which runs by a solar reflector. I don't know what magazine it is from but again is intriguing.

Ah, here it is: the ME 1923 compound condenser. I might say it is a double expansion. There is a triple expansion somewhere.

Have you considered the "Monitor"?

It has been an long and interesting build, wow it looks so good! Can't wait tell you lets us know what your next project has is store for us! On your next post the steam will be a flying!

Yes. Thanks for reminding me of that one. I have the drawings by Rich Carlstedt. The drawings are for a full size engine and will need to be scaled down and adapted for model making.

There has been a model made by someone, I thimpfk it is on this forum somewhere. I'm sure there are plans somewhere. Let me look in my pile.

OK, have in imperial and metric. Will send later.

This is a link to the drawings on this forum by Rich Carlstedt. USS Monitor Steam Engine Drawings

There are other drawings that are somewhat like the original engine and probably far easer to build but I would like an engine that replicates the original engine as much as possible.
