Do wood arrows lose spine over time?

[Zradix]

Just wondering if the repeated bending of the shaft weaken a wood arrow over time.

Thanks

From an engineering standpoint, short of the elastic limit, wood is considered to never experience fatigue, as does metal, for instance.

So, the answer is no.

Not that I have detected.  I have some plain "field arrows" I bought from Howard Hill Co. in the early 80's and still shoot them.  They spine now as the did then according to my scale.

Might depend on how they're stored.

I don't know about the wood, but I think carbon arrows do and an older man down at the bow shop asked me the other day if I though as it seemed to him they did.

I've heard comments about shooting the spine out of aluminums, don't think I've ever done it myself so it must take an awful long while to do.  I've never heard of or experienced it with woodies.
