Spine Testing?

[Rick James]

When ya'll build arrows and spine test do you put the stiffest side of the shaft against the bow? Or do you not worry about it and just put the fletching on so that it orients the grain perpendicular to the string?
thanks, Rick

That's the way I do it Rick, I buy the shafts from surewood, stain, seal, put points and install nocks the way you described the grain horizontal or perpendicular to the string, shoot two or three bareshaft make sure they spine test well for bow cause I have not yet built a tester and bareshaft is only way I can test spine. Have had no problems with surewoods at all so far, then fletch them up.I check and double check everything I can, but the way an arrow delivers broadhead is ultimate test, and the reason we have to support vendors that deliver a quality product!!!

I go with perpendicular grain. I feel that's the way an arrow should rest on the bow. I've checked spine in both perpendicular directions and not found enough difference to worry about.

grain lines should go parallel to the riser.  I believe that setting the arrow otherwise gives you less controll of the arrow spine = greater flex and greater potential for arrow cracking or splitting upon release.

If you are gluing the nock on so the string is perpendicular to the shafts grain then you are also putting the grain perpendicular to the riser of the bow...thus, you should measure spine perpendicular to the grain of the shaft since this is the way it will bend as it looses from the string.

Read again what Snag said.  He's right.
