As soon as the stuff arrived, Tock set to work. She pulled a table over to the middle of the room, emptying it of the trinkets and decorative items that it housed and setting them on the floor. Then she took out paper, ink, and quill from the items brought to her, and began to draw.
Any good creation began with a good set of blueprints. At first she hadn't been sure what to make. Valerius just wanted 'something to impress him.' But what would impress a man like that? She knew next to nothing about him, except for his secret code writings and his high and mighty attitude.
So she decided on something that catered to those features. A sketch soon followed, with careful numbers lined up in the side of the page to dictate dimensions. Then once the basic outline of what she had in mind was designed, she started with some basic geometry. What she had in mind required certain parts on the inside to fit together just so, without room for error. She had to calculate the total area of the inside of the device, so that she could be sure there was room for the right number of gears. Then she had to calculate the radius and circumference of the gears, to know that they had enough room to move, turn, and then lock the desired parts into place. The final design ended up with twenty metal strips, two inches wide by an four inches long, that had to fit between the gears cleanly.
Some more numbers had to be worked out to get the parts moving in careful unison. Each metal strip would have two gears connected to it, one on either side. The metal strips had grooves drawn in on them to allow the gear teeth to lock into. The turning of the gears would extend or retract each strip. She needed to work out the numbers carefully, in order to know how many degrees the gears would need to turn for the swing radius of the outer arc to move the metal strip exactly two inches in and out.
It took her hours into the night to finish the design. By the time she was finished, if Valerius looked over at them, he would see drawings of a square two feet on each side. The metal strips lined the outer edges, with gears connecting them all to a central point. A very large central gear connected them all. Arrows were sketched next to each gear to indicate the direction of movement. The large gear in the middle touched one of the gears connecting to each strip, as well as a secondary gear in between it and the smaller, tertiary gear connected to each strip. When the large central gear turned clockwise, each of the main gears it touched around the edges turned the opposite way, and the secondary gears turned the smaller tertiary gears so that they also moved clockwise. Once the design was interpreted, one could see that this design would cause the main and tertiary gears to move in unison, one clockwise on one side of a metal strip, the other counter-clockwise on the other side, pulling the metal strips inwards when the large gear turned counter-clockwise or extending them out when it turned clockwise.
The strips extended or retracted into a frame around the main piece, fitting into carefully designed slots. There was no apparent means to power the turning of the gears, no crank or winding device that would give the energy of motion. There was no handle to turn them. Just the large central gear that looked as though it would have to be manually spun in order to move the other parts.
OOCI have a specific design in mind for what these blueprints represent, but unless Val can deduce it by looking at them based on my descriptions, I'm not explaining what it does until I am finished. That way it can be a surprise!
