When you're done, the wings should be almost equal in posture. Did you see how that guy's wing was pointing inward?
1) After you slide the each string (starting with the low E) through the cam slot, pull out all the slack, tighten the cam and bend the string (the end you're clipping off) the opposite direction of the turn. Leave about 1/4" of string when you clip it.
2) Tune the strings as you go (E, then A, then D, and so on)
3) By the time you get to the high three strings, the trem is already off the body (or nearly so). Pull the slack before you tighten the cam! Bend the strings the opposite direction, and clip them leaving about 1/4"
All of the wings will be lined up equally and the shouldn't slip.
