I apologize for being slightly off-topic, though 'Alpharetta' sounds like a dodgy pre-release Cinelli track frame being tested by riders in the San José area of California.

Nah, the chain just had to much slack at the right time. But I solved the mystery though. It was the chain. Because I use the 60t most half link chains are not long enough. So the last half link I bought I added older links to it to make it long enough. Turns out that was the problem and why it would only loosen and tighten at certain intervals. A friend of mine was watching while I turned the crank and he noticed that when the chain was tight it was coming off of the chain ring at the top and bottom. So I went to the bike shop and got a sram single speed chain that was just long enough and bam. Problem solved. I had used a single speed chain before with different chainrings but I had linked it together as well causing the same problem. I am a Dork! It was something stupid easy.

Plus, how do we know that he, or someone else, hasn't spliced two chains together? Granted that is far fetched, but it would a) be another example of uneven chain wear, and b) explain how the chain tension might be tight for one revolution and then less tight. Which the conventional answers offered do not explain. Except for a bent BB axle .
