Just WHAT IS Arrow Spine, & How do you tell if your's is RIGHT for Your Bow Set Up.??
Arrow Spine is the Defliction in Inches of the STIFFNESS of a given arrow. No matter if its WOOD-CARBON. ALUMINUM or even Fiberglass.
What ever your Spine in INCHES is, Devide 26 by that Spine Number & it will give you the Pounds for that Arrow.!! CONFUSED YET.?? LOL
OK, Lets try one then. Devide 26x .520=? RIGHT!
It's a 50# Arrow. OK, What if the Defliction is a few digets Short.?? OK, Lets try one of those too.! Try 26 devided x.441= 58.9569 Now what do I do.?? If the Number AFTER the 58. is 5 or MORE you just go to the Next WHOLE Number. In this case Its (59#s NOT 58#s Same way you do TAX, 5 or more go to the Next Penny.!!
Now, Does Every one Understand how to Spine an Arrow now.??
To Help some of you out that is STILL CONFUSED I'll bring my Spine Tester Tomorrow.
Here is a Spine SCALE so Everyone can COPY it to use latter.!!
