2-Liter Water Bottle Rocket Assembly Instructions and Pictures

While trying to make thicker pipe so I could add a groove and an O-ring, I found that the 1/2" PVC pipe swelled up enough for a tight fit after I inserted the 1/2" CPVC pipe. This became the starting point for my current design. Here are the pictures documenting the process:
