There is no such thing as Spines
I suggest this simple test for doubters and customers alike. Take a steel shaft and a graphite shaft. Place in your spine detector and mark the spine. Now take the marked shaft and put it on your deflection board with the mark facing you. Place the weight one inch from the tip and allow shaft to bend. Mark on deflection chart where the center of the tip comes to rest. Rotate the shaft to have the mark up or down and repeat the deflection measurement. Mark where the center of the shaft tip comes to rest. Most often you will find the two deflection marks about one half a flex apart. HOW CAN THE SAME SHAFT HAVE TWO DIFFERENT FLEXES? The weaker the "spine" the less flex difference you will see!.
This is a great sales tool to use on your customers! Show the value of your services.
Try it!
