How many of you float your carbons in the tub to find the seam?

Not me. I was just never that anal about it. Being naive I figured the arrow companies all made a good product. Just like many other things there are good, gooder, and goodest. And not all arrows are up to their advertised specs.

So now I have a trusty, home made, spine tester and that's what I use. No now I'm getting more anal about such things when I can't shoot well enough any more to tell the difference.

Still, how can I express to others that all these little details make a difference if I don't apply them to my own testing and shooting?

I usually just put them in the shooting machine and get them to group in the size of a 50 cent piece. But it is quicker to tub them and find the seam faster.

Hey Barry how did you make your spine tester?

How's this? Disadvantage of using a spine tester is that it doesn't show the heavy side. It just shows the stiff side, of which there are two; 180 degrees apart. But does it matter?

nice tester...As per Hutch's question.. No, just started using carbon. and in fact never tested spine befor!
I was a back yard champion, a legend amoung my friends. I always bought a doz alum's then fire all 12 at same spot (in groups of 4) mark any flyers, that just couldn't have been me Just shot for fun and keep in tune for hunting.. Now once in a while I keep score when I think That score can be helped buy .0005 arrows with same exact spine. Then I will do that..

I ask this ...why is needed to find the seam? so one may set it 90 drg to the way the arrow bends @ shot ? I must know....lol

For those who don't know. Carbon arrows have a seam, and the old timers
and some new timers, stick them in the tub, and float them. The seam being the heaviest part floats on bottom (at 6 o'clock). They would nock them all the same, and Fletch them the same. So the seams would all be at the bottom. Thus in theory all fly the same.

Interesting stuff Hutch, that's a new one on me. I wonder if the olympic shooters do it?

[SonnyThomas]

Seems some are missing the point. Floating a arrow in water is finding the heaviest side of the arrow, thus what is said to the strongest or stiffest part of the arrow.

bf's, spine tester is just that a spine tester. Weak part of the arrow and indicator gives bigger reading. This is not checking for run out.

Now, I posed this to a few knowledgeable archery notables; Stiffest part of the arrow found, which way does it go to the bow, up or down? Answer most given; Doesn't matter so long as it is aligned to the power stroke of the bow string.

Personally, I shoot my arrows. Numbered, any arrow that doesn't impact as the rest is put aside. I'll spin test them if way out they are put aside for casual plinking. I then come back with nock tune to see if it can be made to impact as the others. Here, I index the nock to the next vane and when that's done and no improvement I'll install a new nock and try again. After this and no improvement I'll refletch the arrow. Usually the arrow is corrected.
