The total (half) is 20.5 grams 41gr before landing? It balances on my Buck Knife at 2.66",(67.53mm),from center hole which would be center of mass right?
Tip 6.9 gr
Ctr 13.8 gr
Center mass Dia 5.32" /135.06mm

It gained a couple grams at my Harbor Freight/ one car garage lab.
Worth while ?? or do I have to go sit in the stands?
Very Clever and simple solution which are often the best!

For years my company spent millions on complex inventory management systems to predict and replenish production floor stk. However far a simpler method was employed a box containing a predetermined number parts that when emptied on the production floor visually signaled replenishment. And the box (Kanban) works far better than any complex software algorithm. Simpler is almost always a better solution.

Again Nice work Frank.
