Intro: K'nex Counter

Hey guys, so here is the project I've been working on for the past three months. 

This is a counter that counts up to 99. It has two ten spoked wheels, that have the numbers 1-9 on them.  So when the first wheel get's up to 9, the next movement turns the second wheel to 1 and the first wheel to 0. It keeps doing this pattern all the way until both wheels get back to 0-0.  

The first thing I had to figure out when I was building this was how to get a wheel with 10 spokes.  That actually came pretty easy. (But they are kind of hard to put together).

The second thing I had to figure out was how to get the whole mech working. That it's self took a good month and a half.  The rest of the time was spent figuring out the face plate and finishing it up.

So, it might be a month or so after school started, but I hope you all like it.
Now let's hear some feedback.
