      Doodling the other night while listening to a Zoom meeting I wasn't really into it but had to "be at". Based on a technical drawing from the late 1800s. Not as cool as Tuna's village but good practice especially for working with multiple curved surfaces.

                      Could be Jim. At least if the wheel was smaller. The one I modeled is 32 in. in diameter and 6 in. thick. It would weight nearly 745 pounds not including the crank pin. Maybe that's more than the mower weighs. πŸ˜‰

                        At that size and weight I would take a guess that it is the flywheel for an oil or maybe hot air engine? Nice technical execution as always!

                          Probably from a steam engine.

                          Thank you.
