Chris's Slew-Crowd Engines
crueby:
And we are there! Got the drain valves made, just a small turned globe-valve shape with a length of screw loctited in, too small to be practical so they are just dummy valves. Painted them, touched up a few scrapes here and there, and got them plumbed up with a common air line. I can run them on my compressor all at once for a little under a minute before the pressure drops too much. The compressor cannot keep up with refilling the tank with all four going, and I had to take the needle valve out of the air line since even wide open it was restricting the flow too much.
First some videos of them all running:

That completes this build. Been a really fun one! I need to decide where they will go on the display cabinets. Either in front or above the Marion steam shovel in the shop, or somewhere in the Engine Room. Not sure yet.
And I know a question would be coming soon: what's next? Well, one that I've been wanting to do for a long time is the oscillating engine from the Diesbar paddle steamer. Michael helped me a LOT with details and pictures of the real thing, which runs on the river near him in Germany. A very interesting engine, uses the Penn valve gear with a slip eccentric for reversing. Here is a CAD drawing of what I've come up with:
I also have the paddlewheels themselves drawn up, would like to model at least one of those to go with the model. They would take up a lot of space to have both on the engine, they are a much larger diameter, but interesting since they have the paddle feathering mechanism on them.
Thanks to all who followed along! :cheers: :cheers: Chris

I follow the HomemadeTools.net forum closely and so get update emails almost daily. So I was surprised to see a note today about material in its new offshoot, BuildThreads.com...

Apparently, their bot is monitoring your excellent documentation of this latest project. Just thought you ought to know.
The engines are simply spectacular. Lots to learn from your descriptions, especially about the techniques and economies of making several similar models at the same time.
I'm really looking forward to the paddle wheel project.

Fascinating Journey Chris :ThumbsUp:
Thank you for sharing it all :praise2:

Appreciate witnessing your amazing talent and will be following the paddle steamer engine build closely.
