Nocking Point

[wingate_52]

Is there a relationship between the bracing height and the nocking point. e.g. If the bracing height is plus 5mm at the top limb, should the nocking point be 5mm above centre.
What do members do. Vary the nocking point between 4 and 15mm and shoot paper tear tests?

To set nocking point bareshaft at 30 metres. Fletched and none fletched arrows to hit at the same height.

Download Murrays guide if you need more details.

(agreed - on both points )
With a new bow, start at 10mm and work down to get the bareshaft in the group at 30.

You're +5mm reference is referred to as "tiller". There are some schools of thought which use this to determine the starting nock point height, but frankly it's irrelevant.

Bracing height (in the normal sense of the word), though may affect the ideal nock position as it alters the point at which the arrow leaves the string, so get the nock point right, adjust brace height to give best group, then recheck nock height is one way to go.

Ok. Heres the newbies guide (I would have thought though that most clubs have a coach/experienced archer who should have explained it to you). This time of year shooting indoors at 20yds. is ideal for getting a rough tune. First of all find the bracing height range (minmum to maximum) for the size of limbs you have, this information should be available from the limb manufacturer, the shop you bought them from, or from Murrays excellent guide. Make sure that you have the correct length of string for your limbs and start with the minimum recommended height and shoot a few (3) arrows.Then put five full twists in the string and shoot again. Keep on shooting and in between ends put five twists in the string untill you get towards the maximum BH ( by putting twists in the string you are effectively shortening it and increasing the BH) At some point in this process you will notice that the bow has less vibration on release and sounds quieter, you may also notice that at this point your arrows are hitting higher. Make a note of this BH with a BH guage or measure it with a ruler or mark it on an old arrow you dont use. This is your best bracing height and whenever you string the bow it should be set at this height.
The next step is finding your nocking point. Sorry to say but you are going to have to tear the fletchings off one of your shinny new arrows, this is called the bare shaft and it is always a good idea to carry a bare shaft to periodically check your tune (I check it about once a month or whenver anything is changed on the bow). Shoot a couple of fletched arrows and then shoot the bare shaft, if the bare shaft is hitting above the fletched arrows your nocking point is too low, if it is hitting below the fletched arrows it is too high. Move the nocking point untill the bare shaft and fletched arrows are roughly in the same verticle plain (only move the nocking point about 1/8" at each time). The bare shaft can also tell you how well tuned your arrows are to the bow by where it hits in the horizontal plain but thats a whole new ball game.

thanks

to set a nocking point i put the brace hight thing on then set the top of the bottom nock at 1 8th of an inch above the horizontle then put the top one on above your nock this will give you a good start then tune away

ok

heh funny
