I've just put together 160 chain master links. That much practice makes you
real good.

My favorite tool turned out to be a dentist pick for installing the spring
clip.

1.slide spring clip into place on one end.

2. put pick on inside of clip opposite end. Lift and rotate clip over other
pin on master link.

3. push down with thumb on back side of clip opposite dentist pick.

4. use pick to push other side of clip into place.

Goes faster than it took to write this. Or, least after you've done a 100 or
so for practice.
