Title: cutting string angle on nocks question
Post by: dragonman on May 18, 2015, 05:47:14 am
what is the optimum string angle that should be cut into the nock for a 70" longbow? I usualy cut them at 45 degrees , this seems to work for my 26" to 27"  shorticsh draw,  but recently made a bow for someone with a 29" draw and the string pops out of the groove at full draw. Was wondering what angles others cut into their nocks?

The angle changes as the bow is drawn, you don't want a sharp edged groove.
45 degrees is ok for temporary nocks, but part of the finishing should be marking where the string sits at brace and full draw and blending in the nock to allow smooth string movement... unless of course you like to hear clicks and creaks like in the movies and to wear out strings >:D
See this blog entry of mine.

I use. Overlays and only file the back, not the sides because the tips are quite narrow.the string can slide freely without noise or wear.
