1. Find the silk screen on shaft.. Mark shaft and this mark goes at 12:00
In shaft clamp at each zone length.
2. Find the balance point of the shaft—measure the BP from the butt and expresse it as a percentage of total length.
3. Next find the weight of the shaft in grams.
4. Mark the shaft in beam lengths measured from the end of the 5” clamp. The lengths should be 41-36-31-26-21-16-11. Remember to mark the beam lengths along the silk screen of the shaft so the frequency stays in the same line.
5. Install the shaft in the 5” clamp on the frequency analyzer. I use the Golfsmith No. 236821. It measures using the strain gauge method and this way you can use the same clamp at all beam lengths.
6. Next using a 205 gram weight take the raw frequency of the golf shaft.
7. From there take the shaft and set it at the 41” beam length and install your 454 gram weight at the tip of the shaft. Use the bore through weight that you can order from the AGCP to be sure you get proper beam length and position on shaft.
8. Finally go through all the beam lengths, if you are using the Golfsmith analyzer anything after the decimal being .5 or greater you round the shaft frequency up, and anything lower than .5 stays the same. Example if a reading is 184.6 then the frequency would be 185 and if it was less than it would stay at 184.
