In the previous post I showed how to make the actual snare. Here, I'll show how I make and attach the support wire and how the snare is used.
My support wires are made of 14 gauge trappers wire. Cut an 8 ft. piece, fold it in half. Put the 2 ends in a vice, grab the other end, the loop, with vice grips and twist. You end up with a 4 ft long, 2 strand, twisted wire with a loop on one end. Here's a pic showing the roll of wire, aircraft safety wire pliers, a folded over wire, and the finished, twisted wire:
