        2x1 CYLINDER STEAM ENGINE 4k.png

        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. Iโ€™m assuming this is a scale model of what was in a full size steamboat. If thatโ€™s the case just how big would this wonderful machine have been in full size ?

            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.

              Another little engine. These are addictive.

              For reference, the flywheels are 100mm diameter.

                  LOL! It does look a little like a cannon.
