Tapered shaft facts?

[fujimo]

i started this topic over on Pow Wow.
i know many of you do not go there very often, but i would really appreciate any valid input on the topic- i value your opinions from here on the bench.

Is a glass half full, or Half empty?
What ever answer is given is wrong in someone's eye's   it could be 48 percent.

cheers mate

I put my $.02 in.

have heard many opinions and ideas on the subject- and have even been known to proffer an odd opinion too   :D  

but wanting to see if anybody has some facts- maybe to quell some of the mystique!
thanks fellas!

I like cold hard facts too, but unfortunately they're a little harder to come by than opinions and theories

When I was learning to make cane and hardwood shoots arrows from Art Butner(artcher1)he taught me that the natural taper of these shafts allowed up to 10# decrease in the effective spine over the static spine. He explained to me that the taper allowed the arrow to get around the bow easier thus making them more weight tolerant like adding or subtracting length from a 28" arrow can change that effective spine. I've used his calculations for quite a few years now and it works for me.
I have a set of fully tapered ash arrows that seem to fall in the same category. I also have a set of rear tapered(last 9")poplar arrows that act similar but don't seem as effective as the full taper. All I have to go with is my perception of how they fly for me. My brain is too simple for complicated mathematical formulas. I prefer to follow the K.I.S.S. rule!

Yup Pat, my brain haint a real whizz bang either.. LOL

But rear tapered shafts fly better because they recover from paradox sooner and have more foc.

so true Jeff!    
thanks Pat-need to think about that some!
i taper my shafts too- and by all appearance they do seem to help- but why and how, is the elusive answer!

I have broke so many wood shafts it makes me wonder..!  I'm going Carbon at least for shoots and practice.

That is pretty much it.

It seems to me that tapered shafts really shine, out of selfbows where you are not close to center shot. Asking an arrow to flex more to get around the handle, it helps when they recover faster.

Sorry, no hard data from me, just experience
