ARRRRHHRRR!!!!! I just snapped a ring!!!! I feel like such a numb nutt. I didn't even do it while ringing the piston. I did it when I was turning the crank to get the #2 rod at tdc to get the piston on. As I turned the crank, the #3 piston got hung on the lower end and snapped the middle ring. But now that I type this, it seems unlikely that it happened like that and that I probably snapped it while putting it on the piston. Well either way, I guess it's good at least that I found it before I put it all together.
