Thread: Bare shaft tuning

Hi there,
I don't shoot compounds so I can't help with the how corrections.
What I can tell you is the process to bare shaft tune to get to broadhead.

You first shoot 3 fletched arrows and 3 bareshaft from a close distance, like 3 meters to start with, angles and groups in between the 2 will tell you what to change.
Because you shoot a compound, if you are decent you are going to destroy your arrows, so shoot 3 different points on the target, one bare and one fletched arrow each.

For trad bows, we change the weight of heads and lengh of the arrow to play with the dynamic stiffness of the arrow. (basically, if you had some weight a front its more bendy, if you shorten the arrow its less, and vis and versa). On a compound, you can "cheat" by moving the alignment of the arrow.
The theory behind it is that fletching corrects imperfections, so you compare fletched (corrected) against bareshaft;
You can correct as per the image bellow

Correct until your bareshafts and arrows group the same, then go back a bit till you have a good group at 20meters (bareshafts won't fly with as a good ballistic, at some point the will shoot lower). When your group match both your fletched and bare should point in the same direction.
You then repeat the same process with Fletched arrows with BH and FP, the theory is a broadhead will work as a wing as well and mess with the flight. so your corrected is the fletched non-broadheads.
Things to consider if you have erratic results and out of alignment results.
Some BH shoot like S*** favor multi-blades and or really high ends double blades. If you cant get it to work it might just be that your shafts are too stiff or too flexible. You can only correct so much by moving the biscuit.
