Tradhunter - Traditional Archery Bow Hunting Forums

Ok guys since im transitioning from trad to a little more modern arrow i need some help. I still want to use wood but with the correct size, weight, and with modern points/broadheads.

1. what is spine size.....is this the diameter of the shaft? and how do i choose the correct size?

2. weight and stiffness of arrow. How are these determined? and how do they affect performance?

3. do right/left feathers make a difference? (i have no idea what i just wrote and dont know what it means....lol)


Heres a pic of the arrows i make to give you an idea where im at.....this is obviously to lightweight for my modern longbow i have on order.



having trouble posting pic w/ imagelinky tells me cant determine size...as soon as i fiqure it out ill post it. using imgur instead

The spine weight is how stiff an arrow is .

The spine weight is how stiff an arrow is .
The diameter is just that .
Sorry my phone is not working on here so good .
I will try later .

Here's a good read that explains arrow spine, if I copied the link correctly...

What the others all said. Tony, your link is good.
Using left/right feathers is strictly personal preference (from what I'm told). Just don't mix up L/R feathers on the same arrow. Also, If you plan to use single-bevel broadheads, make sure your bevel is the same as your fletching (don't put a left bevel broadhead on a right-fletched arrow).

Glad you caught that cookies; I missed that question. Basically right wing feathers come from the Turkey's right wing, they will spin your arrows right, left just opposite. I use both and can tell no difference with field points, what cookies said on single bevel broadheads though.

Spine is the ability of the shaft to resist flexing/bending

See above....

No. It was once thought that right-handed shooters should shoot left-twist and vice-versa but that's been disproved as the arrow does not begin spinning until after it's cleared the riser. Choose either style as long as all three feathers have the same twist.

Thanks for the replies and the links. This is very helpful. After reading all the comments it made me aware of other things i did not know of, very interesting and alot of great comments. I guess i have some reading to do.

I really don't want to get into right/left thing if i don't have to, just spine size/weight/length. As soon as i educate myself i will post my arrow specs for my bow and let you guys confirm if im on track or or way off in left field.

Easier to post pics of your target block with arrows in it, than just listing specs (more fun too!!!) If the arrows group at or near where you intend them to, is say your gear is performing just fine!
You'll find that's the big separator between this site and most of the others: performance is measured more by accuracy, feel and enjoyment than by numbers and specs.
