Modelling the geometry

The technical drawings that we have indicate that there are two tuning plungers attached. There is also a pumping hole and some device that might be the coupling loop. We ignore the pumping hole and the coupling loop now and model the two plungers.

**Figure 5.1:** The technical drawing with the plungers, pumping hole and feeding loop.
