well figure your gonna have the arrow pass the riser somewhere on middle of bow , right.... nock arrow on string at that point , raise nock of arrow slightly above 90 degree 1/4" up or so to start, mark your string there. take dental floss or wha have you, i use red fast flight string cause i have it, tie a overhand knot like tying your shoe lace, go back and forth upwards tie one facing you then next on back side go up several ties then back down if you want it thicker, tie square knot or surgeons knot and cut nock string, not bow string !!!!!! burn ends be carefull do not even touch flame to bow string,, press with finger to make a melted spot pressed into nock string, you can usaully twist it up n down your bow string then to set for your needed nock height , thats as best i can explain it.
