Need some tuning help please
« on: May 31, 2010, 09:59:00 PM »
I need some tuning help for my recurve that I bought about 3 weeks ago. I've been trying to paper tune and I keep getting a high right tear that I can't seem to get rid of. I used the arrow sizing "program" that I found here on Tradgang and I checked and rechecked it. It says I need 30 1/2 inch 2213 arrows with 125 grain points. I bought 2213's and left them full length and I'm up to 140 grain points and still can't get rid of the high right tear. I have a 49 pound bow and my draw length from nock to deepest part of the grip is 28". Any suggestions would be appreciated as I'm getting a bit frustrated.

I'd say that you'd need maybe a 2016, possibly 1916.

With out knowing your draw weight I cannot comment on which arrow would be close but if your tear is HIGH and RIGHT then the HIGH indicated that your nocking point needs to be adjusted and the right indicates that your arrow spine needs adjusting. I would work on getting the nocking point right first then the arrow spine.

I couldn't get paper to ever work out for me. I went to bare shaft tunig and haven't looked back. I found it worked best for me. Here's a link to the O.L. Adcocks version of the bare shaft method.

good luck

The quest to improve is so focused on a few design aspects & compensating for hunter ineptness as to actually have reduced a bow & arrow’s effectiveness. Nothing better demonstrates this than mech. BHs & speed fixated designs

May have misunderstood, but I think he says 49 lbs. at his 28" draw.

I've read the bowmaker.net tuning column and I did try the bareshaft method. That showed the shafts shooting in pretty much the same place (or as near as I could tell with my shooting skills) but I still get that high right "kick". I've tried moving the nocking point and it does get a bit better but still can't get it better than about 1" nock high. Is there anything else other than spine and or nock point that may account for the high right tear?

Sometimes nock high is tough to get rid of. It can be a form issue (plucking the string will do it). I assume you are right handed since you don't say. If your bare shafts are grouping with your fletched shafts, your spine should be good. How far are you shooting? If you are too close, the arrow may still be in paradox when it hits the target or goes through the paper. I like to be 15 to 20 yards out when tuning.

One other method, the one I usually use, is to put a big wide broadhead on and see if that is hitting in the same area as the field point.

I don't know what your level of experience is, but it sounds like you need to do some form work before you worry too much about fine tuning. If I pluck the string, my shots go high right, even with perfectly tuned arrows. My advice would be to do some blank bale shooting to groove your form. Also, if you are new to traditional bows, 49# could be a bit heavy to start with, especially for form work.

Hope this helps, and welcome aboard. This is a great place to hang out and learn. It is the best site on the internet!

oh ya and form is more impirtant than any tuneing ever will be, or even can be accomplished.  :knothead:   :banghead:i found bareshafting to be a great indicator as to how my form is .

I'm with Davey Crockett, at 49 lbs your probably better off shooting a 2016 or possibly a 1916.

Jay,
I would agree with the previous couple of posts - I think you are over-spined with the 2213's.
A right tear for a right handed shooter = over-spined.
You might be over-spined enough - so the 140 grain point weight wouldn't bring it back in.  For a 2213 - you may need something heavier in a point weight - way heavier.
Looking at the Easton chart - and making the usual adjustments - you need a 2016 and keep your 140 grain points handy .......
