When using laser to find the spine of a golf shaft how do you determine between the spine and NBP of the golf shaft.
My experience to definitely determine one from the other, you need a frequency analyzer/meter. The highest frequency will determine the spine, lower frequency the NBP. I don’t believe you can do it with a laser tool alone.
When i flo a shaft I seldom find what one would call an NBP and I’m not really concerned with the spine. I’m strictly looking for the best FLO. Once I detemine that, I usually (95% of the time) find FLO 180* on the opposite side of the shaft (not that it’s really important).
I orient the shaft to oscillate left to right, once i get the straightest oscillation, I mark the shaft on top (12:00), and orient the 3-9 position (FLO) to/from the target line.
there are a lot of threads involving this on this website. Popeye made my life a lot easier regarding this. see this thread: https://ralphmaltby.com/questions/question/puring-and-flo-questions/answer/7421/
If you bring this up on some of the other forums, it can get pretty intense!
I read this question with interest. I do it the same way , except when I flo the shaft, I do it top to bottom. I do mark it at the 12:00 position and then rotate the shaft 90 degrees when installing. Am I getting the same result ?
Maybe it depends on which 90*direction you rotate it.
Brad – your way is fine.
Also, the result should be the same regardless of direction you rotate the shaft.
Main reason i twang left to right is that’s the direction the clamp (GW0051) i use moves. I’ve done up and down with my auditor freq analyzer in the past, but it uses to much time. Same as my kaufman clamp I made.
