OK gang, my google-fu is weak today. I know I've seen more than once here at BF a link to a scan of some english (australian?) cycling journal that illustrates an easy way to undo removable links, by working one link's worth of slack up on to the large chainring so the removable link is sticking up, and then tapping -- but now I can't find it.

Can somebody please drop me that link again?

FWIW, I think a better method is illustrated in the latest post on Dave Moulton's blog. This guy's a friggin genius. See also his homebrew headset press.
