Rotary Table Stepper Motor Adapter

I purchased a 100mm rotary table for my milling machine, purchased from [here.](http://www.micromark.com/Milling-Machine-Rotary-Table,8218.html) I wanted to connect a [stepper motor](https://www.sparkfun.com/products/10846) from SparkFun, so I can use an Arduino to control rotating for making gears. The beauty of this setup is that 1 step of the stepper motor advances the rotary plate by 1/80th of a degree, and can do it relatively automatically.

The first step of this project was to design t
