I was hoping the folks that have built them could provide guide to how use one.
Maybe how to tell if it is working correctly?
How to find the stiff side of the arrow,(does the arrow have to be uncut to do this or can you find it on arrows already in your arsenal)?
What spine chart you should be using and where to find it.
Cause honestly I built one and I am not exactly sure if it works right or not.
I went to my local archery shop and bought a pile drive 350 uncut to see if it was working correctly. When I checked the spine it read 7.20 which converted to 360 something and I am not sure if it is correct.
So if someone could guide me along in this pursuit it would be greatly appreciated.

Can someone please tell me what the spine deflection (@28") is on a 2115? Thank you

Looking for a little help, I’m having a bear of a time with broadhead tuning, and I am curious if my arrows are weak. My specs are as follows.

2011 prime centroid
70lb dw
29" dl

Arrows are:
Easton axis 340
Cut at 28.25" carbon to carbon
Firenock aeroinserts @18gr each
125 gr points
Onestringer wraps with double dogs (I’m guessing around 10gr)
Easton xnocks
Blazer fletching a

Thanks for any input

Hi all,

Recently purchased a bear motive 6 70# the bow is set around (65), and have been fiddling around with tuning it today. I ran into some issues as i shoot gold tip ted nugent 55/75 at 28" 100gr tip but had alot of problems with groups going right of the target, which in my understanding is the arrow spine is to soft, therefore I need a stiffer spine. After doing some research on the net my dilemma is do i go with 340’s or 300’s? Keeping in mind that I intend to wind the bow up eventually and possibly use heavier tips. I thought as always you guys would have some great advice so please tell me what you think.

As this is one area that I find confusing, and am keen to learn more about.

Cheers,
Jack

So I go my new Vector Turbo, and had a friend run it with all my specs on his ONTARGET2 program. It calls for a 300 spine arrow, THEN I look at eastons spine chart and It calls for a 340 spine. Which is more likely to be correct? thanks
