QFT! I won't use clip on mater links for this reason. I've seen too many fly off! Btw AMJ aren't you supposed to press the plate into place on a clip master link? UKR mentioned that he just "held" it tight with vise grips to get the clip on... I did a guy's chain who showed up with a clip style. I pressed it together and then just popped the clip on with silicone. Still don't like it...:idk:

I've done it that way with a guy sitting on the bike to hold it in place... in my experience, an impact wrench works just fine for this job but I may be taking a risk and his way is the best/safest.:idk:

At the end of the day, it doesn't really matter how you get the clip on, as long as it locks into the detents on the pins. A press makes it easier to not bugger the clip up (bad), but if you're careful, vise grips will work ok-ish.

If you want to go whole hog, you can safety wire the clip in place, and then RTV it (SOP in some vintage race orgs, and a huge PITA).
