Wehrmacht Enigma


Descriptions, Pictures and Rotor Wiring Procedures.

{{ IN DEUTSCH }}

This exact replica Enigma has been built from parts that were reproduced with high accuracy using highly detailed measurements taken from original Enigmas and Enigma parts. Every part has been carefully measured and constructed out of the same metals and materials used in the original Enigmas or in a few cases out of materials that were as close as possible to the originals. Some of the parts are original new Enigma parts that were recovered from factories that were bombed during the war.

Calling upon over 20 years of experience in studying and working with Enigmas the designers devoted over 5 years to producing this accurate replica. The result is a fully working and absolutely complete replica Enigma that can not be told from an original. It comes in a superb reproduction of the wooden outer box and is complete with 12 steckers.



























ROTOR WIRING PROCEDURES:

The following pictures and descriptions explain how Enigma Rotors are wired.
As you will see, wiring a rotor involves a very complex set of procedures.


1. First, each of the 26 wires is cut to a length of 9 cm.
The insulation is removed from each end by heating it to 450 deg. Celsius.
Each of the ends of each of the wires is tinned with solder (pre-soldered).
One end is then cut to only 3mm length for soldering into the spring of the spring-mounted contacts.


2. The 26 flat contacts that are embedded in the fixed contact plate are cleaned with a drill and counterbore tool.
Then they are pre-soldered and then the wires are soldered into the holes.


3. The disk with the soldered flat contacts is stored for a few days to allow it to return to a completely even temperature.
The disk is then mounted in a special holder so that the contact side can be made perfectly flat.
This is necessary because the bakelite expands (grows) from the heat of the soldering and the contacts sink about 0.05mm deep into the bakelite disk.
The disk is placed in a special holder that holds only the outer edge of the disk.
This holds the disk securely and avoids vibration while the tool removes the excess bakelite material to make the surface completely flat.


4. The fixed flat contact plate with its wires is then mounted above the disk that will hold the spring contacts.
Temporary round spacers are used to hold the two disks apart.
Each wire is then inserted into the hole for the proper spring contact on the opposite disk.


5. The springs are then screwed onto the contact pins and each wire is soldered to its appropriate spring.


6. The wires are then turned in a loop around to the right.
The contacts are brought around into the correct position and then the cover plate for the spring contacts is mounted.
Each contact must be checked to ensure that it moves freely and that it comes all the way out.


7. The wires are then carefully brought into the gutter of the body part.
This must be done very gently, so as not to destroy the insulation on the wires.


8. Before mounting the fixed contact plate with its 3 screws, all of the wires between the touching surfaces must be removed and pressed into the gutter.


9. The wire ends coming from the fixed contacts and the spring contacts must be bent very carefully so that they do not touch the opposite contacts or wires in a conductive area.


10. Insulating tape of the old non-plastic type is wound around the contacts to keep moisture and humidity out.


11. A specially designed and built test device is used to check the rotor wiring.
Each connection is checked to ensure that it is correct and that there are no accidental connections between other wires or metal parts.
