Steam engine Grasshopper
The half-balancing steam engine is a further development of the actual balancing steam engine. It was developed to reduce the space required by the steam engine while maintaining the same performance. The model has a 140 mm flywheel and a total height including the base plate of 190 mm. In this model, the balancing beam consists of two brass parts that have already been machined on the CNC milling machine. All assemblies are mounted on a base plate that has already been engraved. The flywheel is included in the material kit as a cleanly cast raw part.
All materials, screws and accessories required to build the steam engine are included in the kit. All milled parts are prepared to such an extent that they only need to be deburred and possibly drilled. To build the steam engine, you need a lathe, a small drill and a gas burner for soldering larger parts. You also need hand tools, which should be in every “steam engine workshop”, taps M2, M3, M8x0.75, dies M2, M3, M8x0.75, reamer 3H7, 4H7, 6H7, 8H7, files and a drill set. p>
