Beam engine Sophie

The 'Sophie' balancing machine represents a steam engine as it was initially used during the period of industrialization. This model is equipped with the Watsche parallelogram, which is used for a straight piston rod guide. The feed water pump connected to the balancing beam can be made functional. All required parts (material & Grafi:Sil valve balls) are included in the scope of delivery. The model machine can run smoothly and elegantly at 0.3 to 0.5 bar. The balancing machine is a special feast for the eyes, especially at low speeds. With this kit you can build a beautiful live steam system. The 'Sophie' is also ideal as a showcase or desk model.

All materials required to build the balancing machine 'Sophie', model building screws and accessories are included in the kit included. All milled parts are prepared to such an extent that they only need to be deburred and possibly drilled.

To build the balancing machine, you will need a lathe, a small drill and a gas burner for soldering larger parts. There are also hand tools that should be in every “steam engine workshop” (tap M2, M3, M4, die M2, M3, Reamer 3H7, 4H7, 6H7) Files and a drill set are necessary.
