Make a large (150mm) capacitive wheel

I’ve found over the web quite a few ressources for small (ipod like) capacitive wheels. I’m trying to build a large one for a project.

The electronic is easily made with an arduino and CapSense library. However I’m quite a beginner with the PCB manufacturing process and I don’t know if it’s possible at all to make the one I’ve designed.
Here is the fritzing project if someone has time to take a look :

My main concern is about the manufacturing of the wheel itself :

Does someone know if it will work as designed?

It appears to me that you are going at it the right way… What can’t you figure out and what is it that you want to do?

As far as if it will work… I have no clue…
