Unfortunately, I can't understand Sheldon's explanation. Way too many terms I'm not familiar with. I'm going to have to learn some basics first. A video would be extremely helpful, since I'm a visual learner and completely new to this.
Centering the chain ring as described by Sheldon should only be necessary if you find you have binding in some spots. That means your chainring is not perfectly centered. If your cranks turn smoothly with a tight chain and no slack spots then you don't need to do anything further.
