After I had measured and delineated all parts of the Falk engine during its repairing, it was only a matter of time until I started building this half-scaled model. Instead of using cast iron parts for the base, I made by bending and hard-soldering several thin plates, with the other mountings being made of aluminium by milling. The power cylinder consists of a piece of a telescopic antenna tube which is hard-soldered to the displacer cylinder together with the connection tube. The engine starts without problems, but it gets relativly hot because of its horizontal mounting, as the annealing colours of the upper part of the chassis show.
