If ya got a vise, I stick a razor knife in the vise, (you could use just the blade), and pull the hide, (hair side down) against the blade towards you, while pulling out, just a little to the sides while your pulling.
Unstring bow, seperate in half the string, slip in the end of your silencer, then wrap around the outside of the string till you get to the other end, seperate bow string in half again and slip other end of silencer in that. Grap string above and below silencer and give a quick jerk, helps lock it in, sorta. Be sure you wrap the silencer in the same direction your string wraps are.
