I was an Aviation Electrician in the Navy. I still have my trusty wire twister. I can't count how many times I removed and replaced SS safety wire on all types of equipment aboard fighters and helicopters. It is nearly foolproof if done right. To this day, I still wire up fasteners where needed. I'm always surprised how many guys are unaware of how to do it right. But then, any wire is better than nothing. I have used springs in place of the wire. This is especially useful on air cleaner lids.............Bruce
