Another Machinist's Model of a Steam Engine.

Dave R

A twin cylinder steam powered donut delievery device? That would be cool.

In the meantime here's an idler sprocket for #40 roller chain.

Top notch work!

They always are mate.

Dave R

Thank you!.

Here's an animation I did as an experiment with scenes, native materials, and Vray.

What happens when you push the button?

Mike Amos

Another Kipling, I wonder if a little flag pops up with the word 'Bang' on it?

Dave R

BANG! :

Actually that's the cap for the fuel tank. It's supposed to have knurling on it but I was getting bored. There's a nother cap on top of the boiler for adding water that needs the knurling and I have to add a spring and some other details.

Most times when I see your models Jules Vern come to my mind

Dave R

@L-i-am I can certainly see that with this model.

Rich O Brien

I love seeing raw engineering. These days they spend more time compressing it into smaller spaces and then concealing it.

These older designs were purer and showcased the use.

Great modelling too.

Dave R

@Rich-O-Brien I agree. I also like seeing what is possible without electronics and computer controllers. Although it might be a bit anachronistic, modeling these steam engines in SketchUp makes it easier to understand how they work and appreciate the designs.

Thank you!

Bryan K

Incredible work as always!

Dave R

@Bryan-K thank you sir.

Mike Amos

Brilliant as ever, I always see this chap in my mind when I see your steam engines. https://en.wikipedia.org/wiki/Fred_Dibnah

I like Fred Dibnah. He was a cool guy.
