Very nice ! One question is that a glass cup sticking out of the one end ?

[Dave R]

Thank you. The glass is part of the cylyinder. It gets heated with a flame underneath. The piston is the metal round-ended bit inside.

[Mike Amos]

I agree with t'others, really good to see these.

[Dave R]

@Mike-Amos

Thank you!

Another machinist's model. A 2 cylinder engine for a paddle steamer with reversing qear. The paddles are articulated so their angle changes as the wheels rotate. Still need to time the valves and properly align the eccentric straps with the eccentrics and of course add screws and nuts.

Rendering straight out SU2026 with a wee bit of simple post processfor the soft shadows and background color.

Fantastic. I’m assuming this is a scale model of what was in a full size steamboat. If that’s the case just how big would this wonderful machine have been in full size ?

[Dave R]

Thank you!

Yes. My model is based on a small desktop machinist's model. I believe it was based on a real one but I have no idea how large it would have been.

[Dave R]

Another little engine. These are addictive.

For reference, the flywheels are 100mm diameter.

[Rich O Brien]

Are you gonna shoot the 3I/Atlas as it passes?

[Dave R]

LOL! It does look a little like a cannon.

Here's a cutaway view.

Amazing little Gems. No doubt.

Top notch work as always. Model, style and choice of subjects. Top notch.
