Well I'm done with this post but one last thing, I have you beat on the nail and hammer method by 40 years I did that when I was 9 or 10 once, bought a chain breaker a few years later so even at 12 years old I did learn their was a faster and better and easer way to get a chain apart. Maybe one day you'll also figure that out also. I'm done good luck with what ever.... since you don't seem need any help I won't bother with your questions anymore. Good Luck!
