text: Once you have your twist set up cut the wire with your dikes or with your safety wire pliers about anywhere from 1/2 inch to an inch. It's all a matter of taste and you can usually tell who safeties by where and how they form their pigtail.
  The pigtail is just bent over wire to keep itself from unravelling. Another safety feature of safetys. Here is my ruler to give you an idea of pitch of twist on a three bolt safety, just at 8 turns per inch. Anytime you're safetying more than two bolts the rule still applys, to safety if one bolt wants to loosen the others will tighten.
