      You probably won't believe it but here's another little steam engine. This is a 2-cylinder engine driving a duplex water pump.

          If you hadn't mention what it was I would've guessed it was this...

          Homer Donut Eating Machine

          At least I now know what it is you are building!

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

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

                          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.

                            For scale the flywheel is 166mm dia.

                                  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.

                                    @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!
