Because of the presence of the pentagram in many of Bessler’s drawings and his apparent obsession with the number five and 55, it’s been a bit of an obsession of mine too, to try and find some information concerning these apparent clues, that would be helpful.
Nearly every angle inside Bessler's wheel is based on the angle of 18 degrees, the smallest angle used in the pentagram. Others include 36, 54, 72, 90 and 108, all multiples of 18, except one which is 30 degrees. All the angles including some covering angular movement not normally required for a pentagram are also derived from the angle of 18 degrees.
Although Bessler stressed the need for five mechanisms it is clear that he also considered using the odd numbers 7 and 9. This gave him the alternative to fit more of them into the wheels without compromising the effectiveness of the wheel. To fit more mechanisms inside his wheel would require them to operate further out from the wheel’s centre, and make them smaller. But given the huge size of the Kassel wheel, that might have been an option he chose to make. Despite it being almost the same diameter as the Merseberg wheel it only turned at half the speed which might be because it contained more smaller mechanisms, with reduced length of movement in those parts which were designed to move.
Those numbers above 50 which contain the number 2 show the 2 as a Z rather than a 2, but only if they are odd numbers. So in the numbers 52, 72, and 92, the 2 is appears as a Z, but all the remaining numbers use a curved number 2. Notice that number variants start after number 50, this supports the notion that a minimum of five mechanisms are necessary.
I can't prove any of this until I have working model, but I firmly believe that the single number 5 denotes five mechanisms, and the 55 denotes two weights in each mechanism. So in the above image the odd numbers mean you can use 5, 7 or 9 mechanisms, and the Z-like 2s can be read as 2 - or two horizontal Roman numerals, V, representing 5, something Bessler does in numerous other examples. He also uses the letter W to convey two 'V's or 5s.
There are other implications in the above text which I have not touched upon which may help others to make progress in discovering some of Bessler's construction details.
