First wood arrow (shaft) - to be a flu flu nutter

<< < (5/6) > >>

Pat B:
Adding tip weight will reduce the effective spine of the arrow. Spine effects left and right wobble. Up and down is effected by nock point height.

Pat B:
Check out BowEd's thread, FOC%, on Shooting and Hunting. FOC stands for forward of center, referring to weight balance of an arrow, basically weight forward arrows.

Russ:
ok. i think i can do the FOC thing.

What is really confusing me is why my arrow is wobbling right and left. feeling the stiffness of the arrow, it is the stiffest arrow i have. none of my weaker arrows do this. could it be that my string tracks in the middle of the handle at full draw and to the left of the handle at brace height?

Pat B:
If you add tip weight you reduce the effective spine making the arrow fly like a weaker spined arrow.You can also sand the middle 1/3 of the arrow to reduce spine. I think shaft diameter also affects spine.
side to side movement is usually a spine problem.
Every string centers on the bow at full draw no matter if it is center shot or a 2" handle. Having the proper spined arrow can be shot from each well with a properly spined arrow for that bow.
 ...and you thought building bows was tough.  ;)

Russ:
Ok… my foc is around 6%.

Are you sure I should weaken the shaft even though the nock of the arrow is tracking to the left???
