Nock high no matter what

[jmar595]

I have been trying to get my bow tuned for a shoot this weekend for a good while ow. I have the nock left right down now. Now I cant get the nock high down. I tried all the way to almost 1" seemed to go down a bit but seemed excessive. I walked down the string also trying to get it. I shoot two under with a no glove under the nock point. Any help would be good. It is a Browning Nomad Stalker 44#@28" bow.I am shooting 5575 GT full length with a 225 point.

If your bare shafts and fletched shafts share the same mark at a reasonable distance, for ex...your max hunting distance, then further chasing the nock position is mute.

Another example...I enjoy bare shafting out to 40 yards. My interest is only in the bare shaft mark relative to the fletched shaft mark.

A little more info would help with a more educated answer.
What's your draw length?  RH or LH? Are you shooting off the shelf, or an elevated rest? Do you use one nock point, or two? Have you tried shooting split, three under, or with a glove or tab? Have you tried a different arrow set up?

Phoenix is really need more info.. If I had to guess ide say you need a second nock point under the arrow. How tight does your arrow nock fit on to the string. your arrow could be sliding down the string on release.

5575's for a 44# bow ???????, how long is your draw length ?

I have tried split finger when starting out, then tried three under. Just seemed not right, I switched to two under because it felt right. I tried the glove and the tab, but switched to no gloves on the string, again it wasn't right. I have one nock point and a no glove under that, they arent slipping down much, it's pretty much like two nock points with the no glove on.
 I have a 29" draw. I anchor to the back of my jaw. I am a RH shooter with an normal shelf. It is a little past center cut. I am using Velcro for the shelf.
 I got a bareshaft after shooting my regular setup forever, and watched it completely miss the target in a curveball-like effect they were 5575's. I went to the archery store and got a fletched and a bare 3555. It would tune well. I got a dozen 5575's for Christmas and had also just found out about FOC. With the 3555's I cant add much weight, but with the 5575's I have a 225 gr point on the end and it tuned perfect left to right, it's just the nock high now.
 The nock fits on the string about right, I can nock it and tap the string and it will come off. It's not too tight or too loose.
 The bare and fletched hit close, but that nock it too high, even the flecched you can see kick up, then flatten back out, but the bare stays that way. Around 20 yardswas the max I could try.

Have you tried raising or lowering the brace height?

I got this info from a wise old sage who is no longer with us. During paradox the back end of your bare shaft is bouncing of the shelf. If you build up your arrow shelf about 1/8" and no wider than the arrow (important) your problem will go away.

On a short bow like yours if you put much pressure on the lower part of the grip you over stress the lower limb which causes it to pull the nock of the arrow down on release which causes the arrow to bounce off of the shelf. That and using two fingers under the nock amplifies that stress on the lower limb. I experimented with different grip pressure using the high speed feature of my camera and you can see this effect on the arrow. Try using a straight wrist so the pressure is mostly on the web of your thumb and index finger and see if that helps. If it does you will either have to change the way you grip the bow, weaken the lower limb, or get used to a very high nock point. Try it and see.
I'll get some videos showing the effect of grip pressure later today.

Arrow appears too stiff, 2 under throw off limb alignment, and if your grip isn't correct it makes things even worse.

I still see nothing on brace height. If your brace height is too low, that can also cause a bunch of problems. Not saying that's the problem, but one more thing to look at. If your brace height is too low, the string is still holding the nock as the feathers arrive at the shelf and it will bounce.

[jmar595]

I will try different finger positions and retry the 3555's. Can I still get a high FOC with the lighter spined 3555's without cutting them down though?
 I will try building up the shelf up first. That makes sense, because as I moved down it would be high then would be a bit better but still be high and you can see it kick up and hear it a bit.
 I have tried moving the brace height around also, will just have to keep at it. I don't change more than one thing at a time.

jmar595 wait just a bit I've got videos uploading to youtube that really show what I said about grip pressure

[BenBow]

Ok here is the first video that shows the effect of putting pressure low on the bow grip. I intentionally pushed hard with the lower palm of my hand on this video. The bow is 63" nock to nock with equal distance between the top and bottom limb from the string. The nock height is 7/16" above the shelf. I also used and aluminum arrow because they flex more than carbons which helps show the effect. You can also see how much osculation there is in the limbs because the low grip pressure really messes with the limb timing.
I'll get the next video up as soon as it's ready

Here's the second video. Same bow same settings I just pulled on the riser grip with my lower 2 fingers which took the pressure off the lower limb. The arrow still flexes some but doesn't kick up like it did in the first video. Also the bow limbs settle down quicker.

Get rid of the no nock.

Go back to 35-55 with about 225 up front. You are way over spined.

Bare shaft for groups only. Your never gonna get a bare shaft to fly perfectly.

Broadhead and field tips with fletched shafts will give the same tuning results as unfletched field tips.

[BigHink66]

Set your brace first based on sound. Start around the manufacturers recommended height

Make sure you are not twisting the vow string. A lot of people so this. The bow canted or straight but the draw fingers are twisting the string sideways. This will cause the arrow to bounce off the riser or shelf every time. This is especially true on shorter bows.
