              Not a steam engine this time. Instead this is a machinist's model of a shaper. The top part reciprocates forward and back pushing a cutter over the work clamped in the vise. As the machine cycles the table with the vise on it increments to the side after each stroke.

                @Dave-R super slick modeling as is your usual. Curious what is the vintage of this mechanical marvel ? πŸ‘

                  @tuna1957 Thank you. Shapers were fairly common in the late 1800s and early 1900s. There are still some in use today, though.

                          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.
