Arrows

I did get some info. It is from Carbon Express. Their techie informed me that the Terminator Lite Hunter shafts have a spine tolerance of "about" +/- 0.006". I'm still waiting to hear from the "big boys".

Yes , the hunter shafts are not what I would suggest but the select terminator lights are .002 I believe....I will check

[BT]

My bad... they are .003

45/60 - 8.2
60/75 - 9.1

0.003 ain't bad. In fact, from what I can see that is rather good. I read somewhere that arrows with a spine tolerance of 0.015" or less are OK. 0.015" Seems like quite a bit to me, but my experience with that data is very limited. As far as other arrows go, I have heard that Carbon Tech does a good job, but I haven't been able to get hooked up with them.

As speed increases the tolerances have made a real difference in my own personal experience.

My dad used to say that it is better to be thought a fool than open you mouth and remove all doubt - but I don't know what a weak side and a stiff side is.... Given that the cross section of an arrow is a circle, I don't even know what a "side" is!

If you float an arrow in water (A shaft with no fletch, insert, or nock), one half circle will be on top of, and the other below the water. The top side is the weaker side...(I believe due to a thinner amount of carbon thickness, thereby making it lighter), and the bottom ...the stiffer side.

Sometimes it's easier to just rotate your arrows on the nocks, or "index" them to find the right orientation of the shaft leaving the bow. If you have an arrow that is hitting "right" of the others, then sometimes rotating that arrow will "stiffen" it so that it hits with the others. Some people number their arrows, and keep track of where they are hitting, so that they can index their shafts. Getting a perfect Dozen arrows takes a lot of turning, and nock tuning....

Ah yes, it makes sense to me now...

Thanks!

Few shafts are finished in total.
Due to the wrap , most shafts have a beginning and end and therefore have a lapped area which causes a heavy side which is also stiffer due to that thickness.
