Thread: Any Archers out there??

At the moment I'm shooting a 60 lb Hoyt recurve and definitely want to set up my own arrows but there is so much out there. I have a 28" draw length so I'm assuiming 29" shafts would be ideal, target only for now. I want to use a 125 gr fieldpoint but I know there is much controversy between 100/125. And I'm not sure if 29" is best or perhaps 28".

I was looking at aluminum Easton shafts, was going to fletch them with 5" feathers, Easton knocks.

I would keep them at 29inches, and if you feel later that you want to go to 28.5 or 28 inches, you can experiment. 5 Inch feathers are the best, especially in recurve, where it will stabilize your arrow the quickest.

FOC refers to the middlepoint of the weight of your arrow. Remember, if you have an 28inch arrow, the middlepoint would be 14inches (middlepoint of arrow). However, FOC refers to the percentage that the weight point of the arrow is from the middlepoint of the arrow. Thus, if you have a 28 inch arrow with a 14inch middlepoint and a 10% FOC, this would mean that the balancing point of your arrow would be 10% (or 2.8inches) towards the fieldpoint or BH. Remeber, that the higher your FOC, the more leverage it gives the feathers to steer your arrow. Thus the more FOC, the easier feathers would correct your arrows flight path and stabilize your arrow. Please let me know if this makes sense.
Thanks

Thanks for the details SVMAD. It does make sense, so to increase FOC, simply increase frieldpoint/BH grain weight correct? I know eventually a dramatic increase in fieldpoint/BH weight will cause a curvature in the arrow's flight path and one has to aim a few inches higher to compensate for the downward trajectory.

Correct. The best way to increase FOC is make the BH/FP heavier. You can (if you had plastic vanes on) switch from plastic to feathers (since feathers ar far lighter than plastic), so you lessen the weight at the back.

Increased FOC also aids in penetration when hunting.

Just be mindful that if you increase your BH/FP weight, you have to take into account the static (and especially) the dynamic spine of the arrow. Doesnt help much if you increase your BH weight, and the moment you release the string, the arrow breaks up. Remeber that this is because the string is pushing the back of the arrow, while the point is still inert. That means the initial force has to go somewhere, and this is usually sideways. If your arrow spine is not strong enough, you will sit with arrow splinters in your hand.

throw your specs of bow pounds, draw lenght etc on here, so we can help you make a good decision.
