Greetings All,

I'm wondering if with your experiences in arrow tuning you see a wrap make an arrow show stiffer with bare shafting? I know they don't weigh much but seems I've heard it doesn't take much weight added to the tail of an arrow to change the spine and flight...

Thanks in advance, Jason

My experience is that very few people (and maybe none) are capable of seeing a difference in dynamic spine reaction based on the weight of a wrap.

But everybody is different, and everybody has a different opinion. The one thing that is for certain is that if you think it makes a difference then it will.

Wraps generally weigh about 6 grains max, even less for the smallest ones. You would have to be a shooting machine to see a difference. 3 5" feathers weigh about 10 grains plus the drag they add to the tail of the shaft. I have seen some add 15 gr of tape to the tail of a bare shaft to make themselves feel better.

Just put the wraps on a shaft when you start tuning. But I have not seen a difference

I just went to the 3 Rivers spine calculator and 6 grains added to the nock of a 63 lb. static spine wood arrow increased the dynamic spine by 1.6 lbs. Not much help if you are looking to increase dynamic spine.

Ttt archery has a good video about this. Basically if you are taking the time to bareshaft to get a perfect tune it’s worth putting tape on to simulate the fletchings and you might as well add 6 grains of tape to simulate the the wrap while you’re there. I did this the other day and it didn’t seem to effect left/ right but seemed helpful for fixing some nagging knock high problems.

The weight is one of the things that causes the fletching to affect the dynamic spine reaction. But the main affect comes from the drag created by the feather itself.

The drag of the feather has MUCH more influence on how the arrow acts in flight then does the added weight.

Something that affects the dynamic spine reaction of an arrow should have no affect on the porpoise affect or nock location in flight of that arrow.

I an’it that good, God knows but I tune a tad weak. That’s advice I picked up fro the Black Widow seminar years ago. But adding a wrap to bare shaft test shouldn’t be a biggie unless your cutting off rear of shaft during bare shafting.

adding weight to the rear of a shaft is equivalent to reducing weight at the front of the shaft by twice as much. Therefor 6 grains of weight added to the rear is equal to reducing weight at the front by 12 grains. You have to decide if that's significant to your tune.

It should be noted that most of the wraps I've used weigh in the range of 10-12grs.

It makes no difference

If you are bare-shaft tuning, there’s no reason not to put the wrap on before you start.

If you’re not bare-shafting, I don’t think it would make any difference , other than (as Frank said) if you believe there’s a difference, then there probably will be.

10 grains = 1/700th of a pound. About 1/44th of an ounce. That ain’t much.

In bare shaft tuning I absolutely see a difference. Especially if you back up beyond 30 yards and film In slow motion. I think it’s probably more to do with wrapping 7” of shaft more than with the weight. For bareshaft tuning I always add the wrap and wrap tape the same weight as my fletchings around the shaft, where my feathers will go. I trim from the front.

I'll never see the day that I could shoot well enough to tell a difference.

If correct, Floxter’s rule of thumb seems pretty helpful. That said, I have wrapped and unwrapped arrows I shoot together and can’t tell a difference.

Spine stiffness with wrap beats me. But for sure the leading edge of the wrap creates minute drag and that assuredly will slow the arrow. ha

Guys -

Not really sure I'm understanding the question. If you plan on using wraps, why would you even consider bare shafting without them? Kinda like perfectly tuning a bow and THEN throwing on a bow quiver full of arrows.

How much of a difference does a wrap make? Don't know, as I've never used them, but since I favor a slightly stiff arrow, it wouldn't be something I'd loose any sleep over.

Viper out.

Thanks for the input guys! I'll put a wrap on and go for it.

Happy hunting, Jason

I have messed with wraps a good bit. I like them and thank they look great.

If you going for foc then I wouldn’t use them. Personally feel like I have seen the effect on bare shaft tuning in certain situations but I am talking a heavy wrap. The one stringer wraps I shot added 20grs of total arrow weight.

I have read that adding weight at the back of shaft effects the spine more than adding point weight but not sure if that’s true.

Real world shooting doubt it’s a big deal.

When I plan on using a wrap on finished arrow I don't see any reason not to tune with it on a bareshaft, I will also place the lighted nock on as it also adds weight.

As for op question, don't think it makes much difference at my level of shooting at close ranges.

Yeah how true is that Viper the old bow quiver thing. Yeah guilty when I was young and stupid.Thought I lost form .In Asian traditional archery weight was more important to their arrow makers than spine.It generally give fairly close spine which is not critical with thumb ring shooting techniques.These arrow makers in the past would have known of spine but never measured as we do today.I have seen arrow makers vidios ( traditional Korean )with the only check of spine was a quick flexing of a finished arrow .Meditrainean draw is far more critical on spine so western archers have developed spine testers.I don't think wraps would be that important.I could be wrong though Keep shooting Cheers Osr

Agree with you, Osr144. I have been playing around with Asiatic archery and have been surprised at the way a good thumb release with good Khatra can almost eliminate spine sensitivity. Hard to learn but fun!

The reason a release like a thumb ring or thumb tab seems less sensitive to spine is because you are taking up less room on the string and the string doesn't have to roll off your fingers.

Yes but khartra is a special art.If not done correctly is just about the same as a mediteranean draw.If one knows khartra and how thumb release works and does it properly then you will know.I do both and probably still haven't really nailed it .It's just special movements made in conjunction with follow through.Far more to it than meets the eye.Good fun though.Highly recommended . Have fun Cheers Osr
