Spinemeter

Today I tested my arrows for the right spine.

Flexibillity of the arrow , by putting the arrow on 2 point 28" apart
and putting a 2 lbs weight on it
Measuring the flexibility on a scale telling you how heavy a bow can shoot the arrow in lbs of pulling weight of the bow

This arrow has a spine of 43 lbs
