Aliens are my favorite small cam, but after years of use on my trusty set , I've have several recent trigger wires break, or nearly break. Here is an easy fix for Alien cams and it also works great on Master Cams. Do this before all the wires break, otherwise you're going to get your cam stuck.
Needle Nose Pliers
2 Small Safety Pins
Cut out the old trigger wires
Straighten out the 2 safety pins.
Put the points up through the trigger bar, then through the cam lobes, bend again once through the lobe to hold each in place.
Cut some of the material off of the "thumb guards"( which usually hold the pointy ends before you mangled the safety pin) and cut the pointy ends off, leaving a bit of wire to maintain the shape of the bend.
