spine tester chart
« on: March 09, 2010, 08:55:23 pm »
hello all,

i have a general idea about how to build a homemade spine tester.  i am not wanting to use the dial calipar design but the other one(protractor style).  is there a standard chart  to go buy?  how do i mark my spots on the tester for a particular arrow spine?  i hope these questions make sense.

Luke,

Try 2Jays spine tester it comes complete with scale.

AMO spine is calculated as follows

26/(inches of Deflection) = Lbs Spine

Howdy L. Drifter,

Here is a link to the spine tester I built.  (It was easy ;))

This link has a downloadable, printable, colorful spine tester chart...
