How to Make a Code Wheel

Step-by-Step Guide

1. 1

   Step 1: You need two concentric circles (one circle should be larger than the other).

   Punch a hole in the middle of both and attach with a brass fastener so the top wheel (the smaller one) can move independent of the bottom wheel.
2. 2

   Step 2: Drawing over the entire circle

   Use a protractor to get each segment the same size
   -- they should be about
   13.8 degrees each ,,, When writing the letter, look at the inner wheel and write down the letter that is matched on the outer wheel. ,
3. 3

   Step 3: divide into 26 sections.

4. 4

   Step 4: Write the letters of the alphabet

5. 5

   Step 5: in order

6. 6

   Step 6: on both circles.

7. 7

   Step 7: To use

8. 8

   Step 8: determine a number to use a cipher

9. 9

   Step 9: for example: 4.

10. 10

    Step 10: Turn the inner wheel that number of turns (so A >> E

11. 11

    Step 11: B >> F

12. 12

    Step 12: For additional complexity

13. 13

    Step 13: use a cipher that changes on each letter (such as the digits of pi or the numerical digits of a sentence).
