​​​NOTES​​

​​1. The above chart is based on the use of a Scandium® shafts that have the same balance point on all 42" gram weight blanks and a tip insertion of 1.25".

​2. A grip weight of 52 grams and 2 grams for tape was used for this calculation. A change in grip weight
of 4-5 grams will change swingweight by 1 point. Lighter grips increase swingweight; heavier ones
decrease it.

3. A change in head weight by 2 grams will yield a 1-swingweight change in the club. Heavier heads
increase swingweight; lighter ones decrease it.

4. A change in shaft weight of 9 grams will yield a 1-swingweight change in the club. Heavier shafts
increase swingweight; lighter ones decrease it.

5. A 1/2" change in the length of the club will yield a 3-swingweight change in the club. Lengthening
the club increases swingweight; shortening the club lowers it.

6. The above chart is based on a standard golf club lie. A change in 2-3 degrees of lie will yield a
1-swingweight change in the club. A flatter lie increases swingweight; more upright will decrease
it. This change is caused by the position of the weight in relation to the balance of the club. By
flattening the lie or moving the toe and the weight away from the fulcrum of the scale, creates a
heavier swingweight. The above calculations above used a 14" fulcrum.
