Spine; Grain?

[islandboy]

I am building some arrows from cedar, and maple.  Spinning them through a dowel maker and planning to taper.  I was wondering about arrow spine.  Do you measure wood Arrow spine with the grain vertical or horizontal? Or both and take the average? Does it even matter?

See the grain rifts in this picture?  Those points should be on the side of your shaft as it sits in the spine tester.

 

Hope that makes sense.

Like Grey Taylor said- that means your grain would be vertical, and when shooting the arrow it will be horizontal.

Here is an image of what I understand you to be saying:

   

The grain runout was a suggestion from another site.  Suggestion was that, should the arrow fail, the remaining shaft would fly up and away from your bow hand.   :eek:    Ideally there is no runout.

You got it!
