I have been kickin' around ideas used in basic coding and encryption and I wondered if anyone had did extensive modulo arithmetic on the numbers surrounding the central glyphs on the various dials. I have begun some testing to see if I dig up anything. For the uninformed modulo arithmetic is expressed ( operator 1 % operator 2 ) where
op1 is your first number, the percentile stand stands for modulo,
and operator two is your second number. To arrive at the answer
to this expression, you divide op1 / op2 and the answer is the remainder
which is left over. This is a very common operation in both encoding and
programming and might help us figure out the second/third parts of the puzzle.

The second idea I have concerned the tic-tac-toe. I remember somewhere, I think in one of CB's clues, about 3D Tic-tac-toe
One possible explanation also concerns aligning the gears.
if you look at the numbers along the gear as a square rather than a
circle, then you could have this type of design

10
66 4
20 L 15
15 80

14

the four corners of the square are ten, twenty, fifteen, and fourteen. the central glyph would be the center of the square. I remember playing a tic-tac-toe game ages ago that had three of these type designs stacked upon each other.

I am not sure if this helps, but it occured to me that it might be usefull.
