Adding a quiver changes spine?
 

I added a quiver to my LB.....and a respected trad archer here told me I have changed the spine on my arrows, now.

I have noticed some small change in flight......but I never would have dreamed it would change my spine.

Can someone explain why?

It won't change the spine of your arrows-it physically can't.It may change the shooting characteristics of the bow.A slide on quiver(or strap-on)that's sittingat the fade-outs could affect the way it shoots

RE: Adding a quiver changes spine?
 

I agree, the added weight changes the way the bow shoots, with any quiver, and bow! Jeff make sure you have quiver straps from the quiver off the working limbs as far as possible, have then close to the grip on the riser! I had to fiddle around with mine a bit to get it to shoot good!

RE: Adding a quiver changes spine?
 

yea, what they said.
A bow can be affected by making any changes it to, quivers,changing the shelf or sideplate material, adding/subtracting string silencers, etc.
You need to shoot it and see how things go, you may need to go back thru the tuning pricess.

I'm thinking you probably are going to shoot better with a quiver on, a little added weight and your bow shouldn't jump near as much when you release. Kind of like a stabilizer and a compound. The spine thing the Trad guy said to you, I've never heard of that.

Adding mass to a bow affects the tuning of the bow and will typically causethe arrow to act a bit stiffer. It's not that it changes the spine of the arrow, but it affects the dynamics of the bow during the shot. The slide on quivers usually have more an affect than the ones that bolt onto the risers. With the slide on quivers, you've got two things going on. The first is determinedbyhow far down you slide it onto the fade. The closer youslide it downtoo the riser, the less itaffects limb movement and energy transfer to the arrow.Conversly, the further up the limb the quiver is placed, the more of an effect is has on limb movement. It's like adding mass weight to the limbs. The other isadding mass to any bow affects the movement of the bow during the shot. When you release the string, the arrow isn't the only thing thatmoves and flexes. The whole bow does, not just the limbs, to a certain degree. This movement, even though slight,plays into arrow clearance.Increasing the mass weight of the bow changes the way the bow itself reactsby decreasing the effects of residual energy andthings likebow hand torque.

That's good stuff, Chris. I guess I should have said it affects arrow spine.....and not that it changes it (well....yaknowwhatimean).

That makes sense....and my arrows are acting a bit differently........ESPECIALLY on shorter shots (if that makes any sense). Longer shots.....it seems to correct itself.

Yep, I won't use a quiver attached to my longbows. Fully loaded with arrows, made it close to impossible to shoot well. It can cause you to torque your handle and get bad arrow flight.

Yep, the fletching drag starts kicking in and straightens things out.

I don't like bow mounted quivers either. When loaded up with arrows, it makes a bow feel really lop-sided and off balance to me. The only bow mounted quiver I've used is a Kwiky Kwiver that, once I get to my stand, I take off the bow and mount to the tree. I never shoot with it on the bow. I've never put one on a longbow. I opt for hip quivers instead.

Personally, I don't like how a bow quiver throughs the balance of the bow off. I don't think I ever had one on long enough to seehow the bow reacts concerning tunability.
