New String Drastically Affecting Arrow Flight
« on: November 27, 2011, 03:43:00 PM »
Hello All!

A few weeks back I purchased a new string for my bow and I am having all kinds of issues getting it tuned. I was wondering if I could get your thoughts? I have always had excellent results from bareshaft tuning...this is the method I am using now. I have the fish tailing problems worked out perfectly...these shafts fly really straight.

The problem is porpoising...They fly nock high no matter how high, or how low, I set the nocking point. Any thoughts?

My first thought was that I had a form issue and was bouncing the shaft off the shelf. So, I put on my old string, shot a dozen or so bareshafts and had perfect arrow flight every time. Then I put the new string back on and shot nock high every time.

Info that may help: a)I shoot a recurve, b)I shoot three under with a glove, c)56"amo, d)Beman 400 Shafts...shot them for 3 years now with no issues, e)200 Grains up front.

I'd love to hear what some of you pro's might be thinking. Thanks for any help you can give!

Matthew

Is the string made of the same material as your last? and are the nock to tight on the string, that could keep the arrow on the string and make it jerk off and cause the arrow to porpois.

You might want to put your old string on and see if the problem goes away. If not it might be a form issue. You could also try a nock point below the arrow as well as above to make sure the arrow isnt sliding down on release.
Double check all the basics as well, string material, brace etc.
I have never had an issue with a string other than nock fit due to strand count or material.I started twisting my own a few years back for consistant results.

Your string may be a little smaller in the serving which could cause your nock to be moving down the string at release.  Try using a nock above and below your arrow and see what happens

Like the others have said......nocks to tight and or your nock point to high or low!
