Tuning your Arrows to Your Bow

 

Nock Height

Nock height is a very personal issue relating to your release, shaft size and type(carbons, cedars, etc). We recommend that you start at 9/16“ and move up or down ( min. 1/4 ”max 1”) if necessary to get consistent arrow flight. You need to find the spot that is right for you. Nock height can cause “ porpoising ” as the arrow slaps off the shelf from the nock height being too high or too low. Point of impact can also be adjusted slightly up or down with nock height changes.

To start with there are several different ways to get your bow shooting properly. This is the way I prefer. Make sure your bare shaft is setup the same as your broadheads, as far as field tip and broadhead weighing the same. I like to shot a bare shaft into a foam target at 10 to 20 yards. You need a straight shaft with a field point, spin it to make sure it is straight, if it isn’t pick another shaft. This is important. You will probably need several shafts because you will probably bend or break some if your spine is way off. You should be using the same weight field point as your broadhead

Starting at 10 yards shoot a fletched shaft at your target; this will give you a reference. Now shoot your bare shaft.  Check the entry of the bare shaft compared to your fletched shaft.

1. If the point is high and nock is low you need to raise the nock point on you string tune2tn

2. If the point is low and nock is high you need to lower the nock point on you string.

3. It is possible to have #2 if nock point is way to low, causing it to bounce off shelf.

4. At this point get it as close as possible, don’t worry at this point if it isn’t perfect as spine with effect it also.

Now’s the time to get the spine right for your bow and your shooting style. Remember that every shooter is different so you can’t have someone else tune the bow you will be shooting.

This following is for right hand shooters. Left hand shooter is opposite. Make sure the shaft is straight; don’t be wasting your time with a bent shaft.

1. If the point is left and the nock is right your shaft is to stiff. You need to pick a lighter spined arrow or start with a longer shafttune2btn and cut off the end ” at a time until close and then ” until you reach the proper spine.

2. If the point is right and the nock is left your shaft is to under spined. You need to go to higher spined shaft

3. At this point your shaft should be entering the target the same as your fletched shaft.  If not, keep repeating all steps

4. If your spine is very close you can change your brace height slightly to fine-tune it.

I personally like my nock point to be where the bare shaft hits target with the nock a little higher than the fletched shaft.

Also, I like the shaft to be a little under spined. The actual setup of these pictures is of a Cougar 58" 53# @ 26" using a Carbonwood 3000 with a 250 grain field point. For me this is a perfectly tuned arrow, as I said for me. You may find you need a little different setup

I also move back to 25 yards or more the closer everything gets to being right and continue to fine tune the shaft to the bow. It is important that you are fresh and not tired when doing this. You need to be consistantt in your style.

Once everything is right write down the brace height and the setting for your nock point on your string. If you can not get it perfect I’m sure you will be a lot closer than you were. Go ahead and tune your other bows the same way, you will find every bow is different. It is very possible to have your field points and broadheads  flying the same.
