Title: Spine tester
Post by: mzombek on December 28, 2014, 10:03:00 AM
I am looking for a post about 2 weeks ago that  was posted. I did the search thing, but could not find it. It had to do with a spine test gauge chart that you would use on one of the testers that use a pointer, that could be printed to scale. It had different spines such as aluminum and wood.
Can someone direct me to the site?
Thanks for your help in advance.

I think you are referring to the spine tester made by Oak Creek Archery.  It was posted 12-19-14, new spine tester.

AMO has a chart by deflection measurement (2# weight hung between 26" centers)

I built a spine tester using their numbers.

The AMO (26" centers & 2# weight) chart is easy to reproduce.  Simply divide the measured deflection into 26 and the result is the pound rating.

Example 1:  If you have a measured deflection of .500 then ---  26/.500 = 52#

Example 2: If your measured deflection is .625 then ---
26/.625 = 41.6 #

That's how the above chart is made.
