Title: Nocking Point (too low)
Post by: Bowmania on March 10, 2007, 07:47:00 PM

I'm bare shafting and keep getting an indication of NP too high no matter where the NP is.  I know that a NP too low kicks the shelf showing it too high.  I keep moving and shooting, and moving and shooting, too high, too high, too high.

Anybody know of a way to get an indication of too low?  To me, then it would be a simple matter of moving it up a tad and getting it correct.

Unfortunately, it is not always possible to get a nock low, either because of your form or because of the tiller of the bow.  If you want to see which it is, you can temporarily mount an arrow rest 1/2 - 1" above the shelf, and shoot your bare shaft from the rest.  If it is a tiller problem, you may be able to get a nock low shooting from the arrow rest, when you couldn't shooting from the shelf.

If your shooting a canted bow it might be an indication of a spine problem. Hap

54 lbs at 29 and the arrows are a deflection of .500 with 125 gr tips.  Bare shafting show the spine good.

Shooting off the shelf it is unlikely that you will be able to get rid of all the nock high. For a right handed shooter, shooting from the shelf a bit of nock high to the left is normal. The reasons are that shelf and plate prevent the shaft from going in those directions. I start with my nocking point where I know it is a bit to high, like 5/8" then I lower it a 1/16" at a time until the nock high condition starts getting worse and then back it off to the best postion. On the bright side, mine have only varied between 3/8" and 1/2" over numerous bows and 40 years and I think all of that is due to different shaft diameters.

Are you canting the bow when paper tuning? I had a nock high tear I tried to fix for a couple weeks without sucess till a light went on upstairs! When you cant your bow at a 45 degree angle a tear straight up is a spine issue, not a nock point issue. All I did was switch to 150 gr points from 200 gr and I got perfect tears. Felt like a bit of an idiot when I realized that.

Try adding a second nock point below the arrow nock. This will eliminate one variable in your tuning quest.  It's not always necessary but it has been the ticket for me on a few occasions.  Now I shoot two nock points on everything all the time.  I'm 3 under though. Are you?

I'm split and don't cant.

Rick,  My best paper rips are about 3.5 inch and ocur about 3/4 to 7/8 OVER THE SHELF.  A fletch arrow shows a good rip in this area (3/4 to 7/8's).  Seems very high to me.  Odd that bare shafting is about 3.5 bare under fletched.

I have an old bow that shoots a bare shaft like a bullet hole through paper.  So this concerns me.
