Arrows with different spine in different orientations.

(1/1)

gfugal:
If an arrow has different spine depending on how it is layed, how do you determine which side to face where? Where do you put the weaker side vs the stronger side?

Pat B:
Most wood arrows have different spine on all 4 sides. Put the stiffest side against the bow and if possible(rarely is) the second stiffest side down.

Just what I was looking for thanks. Just for clarification, what do yiu mean by the stiffest side. Is that "side" the direction the arrow bends towards or the side that faces up when you test it. Thise shod be opposite. In other words is the tension side or the compresion side against the bow?

Pat B:
When you put a shaft on a spine tester the up side is the side the tester measures so if that side is stiffer than the other 3 sides place that against the bow. Don't worry about the second stiffest side, it rarely works out resting on the shelf. The side against the bow is the important side.
 With dowel shafts you also have to consider the grain "flames" to determine the nock end. Once you have determined that then do your spine testing. With shoot shafts the butt end(bottom, bigger) is generally the point end because the grain is around the shaft eliminating and grain variation.
