Brace height and nock point

[acollins]

When setting my brace height, do I need to move my nock point every time I add twist to the string, or does it not effect it.   The bow is a DH Hunter 50@28. I started at 7.5 on BH.

Thanks

The real answer is to check it and see, each time. One twist may not affect it, several might.  Checking will tell you.  The fact that you need to shorten the string tells you something stretched or moved.   At least..... that's what I think.

I agree with Chuck

I like to use a tie on nock while setting brace height because it's easy to move, then just move it up and out of the way and add a brass one once brace is set.

If you change anything just assume everything is off until you confirm otherwise.

Yes . . . but.  The change will be minimal unless you are making a very large change in brace height.  


I'm not going to do the math, but if you think of a bow as two right triangles with the string being the two opposite legs (one being maybe 1-
3/8" longer than the other - however far your nock is above the perpendicular of the deepest part of the grip (not the shelf) to the string) and the brace height being the two adjacent legs.  If you change the base 1/4" you are not changing the difference in the two opposite legs very much at all.

Try bare shafting after you add any string silencers and get it approximately set.

And make sure you make the same number of twists on the upper half of the string as the lower half.

I have always assumed so. I break in a new string by leaving it strung overnight, shooting about 100 arrows, then overnight again.

I then use masking tape as my nock point while i figure out brace height. Masking tape is pretty stable while shooting, but super easy to tear off and do over should the measurement change.

I then tie on a permanent nocking point, but I don't try and tie the type guys talk about that will screw up and down the string. I want my nock fixed and permanent.
