Title: Parallel vs Tapered?
Post by: stringstretcher on March 17, 2012, 01:52:49 pm

Here is a question for you arrow smiths that I would like an answer too. We all know how to measure spine of a parallel wood shaft. How is the spine measured and from what part of the wood shaft on a nock end tapered wood shaft? Let's just say a 14" taper? And would a full length tapered shaft be measured the same way as a parallel?

I'm not an arrow smith but find with my barrel tapered I need to go 5# heavier spine than with parallel. Spine is still measured from the stiff side center of the shaft. The barrel are tapered 10" from each end 23/64 to 5/16. If you like high FOC then taper the nock end only.

Spine is still measured the same way - 2 pounds at 26 or 28 inches. 

That said, I usually spine mine prior to tapering - and then never go back and re-spine them.  My way may not be yours.

A spine tester has 26" supports but the results are extrapolated to 28". Jawge
