The rotors consist only of a few different parts, but most of these are relatively complicated to manufacture. I started with the large wheels which are spin cast out of Zamak, a special zinc alloy. The small levers which will fix the so called 'Ringstellung' are also spin cast parts.

The small brazen parts are the contact plates. They are quite easy to produce, the challenge is the enormous amount which is needed. A single M4 Enigma machine with all its rotors requires 286 of those. I am very lucky to own such an excellent turret lathe to do that tiring job. A video of the contact pin manufacturing you can see below.
