Go to local range and paper tune, get about 5yards and shoot through paper to see if arrow shoots straight or has whip in arrow, you can really tighten groups by doing this.
Don't want to hijack the thread, but how do you tune with bare shafts? Is it by adjusting the brace height? I have a couple of sets of arrows that are in the right spine and group some, but I can see a slight porpoising sometimes in flight.

Check the link above your post.( Click on Bow Tuning ). Step by step to a great shooting bow.
I use Stu Millers free DSC program to give me a tunable arrow. Then I fine tune by adding or subtracting point weight and/or by raising or lowering the brace height. Then I paper tune. I don't bare shaft tune.
This calculator was developed to aid the traditional archer in defining the appropriate arrow setup to match a given bow design. That formulas are derived primarily from modern deflex/reflex longbow and recurve designs based on actual shooting experience coupled with basic engineering principles.
yeah I'm shooting consistent 4" groups sub 20 yards and 6" outside of it...it's consistent but not consistent enough. Todd you ever have a day we can meet up and go through the tuning process?
We have the shoot coming up Sunday. I adjusted my brace out quiet abit and the bow is significantly quieter and smoother already. I believe I will adjust the point weights out for right now and see how that does initially. Too much to change and relearn before the Cowtown shoot.

I live 15 mins from Cowtown and will be out there during the week preparing for the shoot. With work slow , I have also been hanging out at Smithfield alot. Give me a call , Todd 817-228-8061 when your free and we can arrange something.

the dynamic Spine calculator works really fine! First i choose an arrow i want to shoot and then trim it t the right spine via changing pointweight and lenght..
As the arrow is calculated i make three arrows with the data the DSC said.. and then i papertune... then if everything is ok i make a complete set arrows
Since I have two 66" bows, 42# and 37# recurves, I have 10 aluminum test arrows of different spines in 32" lengths. They are: 2013, 2016, 2212, 2114, 2213, 2018, 2215, 2117, 2216 and 2314. These spines will accommodate my 30" draw length shooting 32" arrows. With Stu's DSC program, all I have to do is change point weight and brace height to shoot any of the above arrow spines. It takes me 10-15 minutes to find me a tunable arrow using Stu's DSC program. Then comes fine tuning. I could never do this with the bare shaft tuning method.
Since yesterday was a warm day, I decided to play around with some lighter point weights for my 2114 and 2117 arrows. Using the DSC progam, after a little experimentation with point weight and brace height, I came up with the following which was confirmed by paper tuning.
I never would have thought I could shoot such heavy, GPP (grains per pound) wise stiff spined arrows out of both bows. But, the 2114s and the 2117s fly like darts out of both bows and there is surprisingly very little arrow drop between 10-20 yards. Both the 2114s and 2117s pound my bag target too with a nice heavy thudding sound. More like destroy my bag target.
With bare shaft tuning, I would never have considered the 2114 for my 37# bow or the 2117 arrow for my 42# bow. The only thing I ever got out of using the bare shaft tuning method was lots of aggravation. Stu's free DSC program, at least for me, is the greatest thing since sliced bread.
