Also, different weights of arrow heads changes spine. If the arrow shoots well I keep it, if the arrow does not shoot well, I "foot" the arrow, add or lessen the head weight, sometimes add or change to different fletching. I hate science and math but love accurate accuracy. Good video and thanks Airborne!
Since I own bows from 35-55 lbs I made a dozen arrows of every possible spine. This makes it much easier to figure out the spine for a given bow. No calculations required. Just shoot them all until you find a favorite. I enjoy making arrows as much as shooting them. I would like to make a spine tester to test wood shafts for consistency. Something simple like this would be perfect.
I also have bows with various draw weights (30 to 55). I also have carbon arrows with different spines and used different field point weights to determine best results. By doing this I had a better form overall.
So far as a noticed, spine is kind of a preference thing. I use #60 wood arrows with a bow #45@30" that shoots exactly where I want with the sight picture I want. I used #40 arrows before that, but I found they were off to the left ( I'm shooting a hungarian bow right handed, on the right side with thumb), but I still managed to find the gold with those as well anyways, just had to adapt.
My bows are from 32-45lbs. I shoot 35-45 wood, #7 glass, .500 carbon, and 1916 aluminum from 26-29in and 350-500 grains in total weight. They all fly great, and I score about the same.
Nice can of worms you opened there. Even I am confused now. Isn´t measuring at 26" for wood arrows only and 28" for aluminum and carbon? Also, (quoting easton) the weight is 1.94oz and the arrow length has to be 29".
The old standard was 2 pound. That standard was used up to 2023. I also believe they standardized the distance. But I could be wrong on that part. As for arrow length, they use the same distance regardless of arrow length. The Standard is suppose to be 29” arrow, but everyone does not follow that.
Looks like to me this is just another marketing trick :P They confuse us so next time we have to buy the 'correct' arrows, we have to buy multiple to see what is the one we actually need :P
@@tiobi6633 Not sure about that. I buy the same Arrow since 2018 and they all tune the same. When I switched from VAPs to x10 parralelpro I still bought (nearly) the same spine and got them tuned within expected differences. You just try different spines at the pro shop and buy the closest one.
I really believe a broadhead on the front would be a determining factor. The fletching would not be able to correct like a target point. Indoor eeh, hunting a different story. Could probably see differences shot through paper, not so much with target tips shot into paper.
Not to sure about the broad head. There is a reason they put the fins on back of all projectiles. Many good target archers are also good hunters. The same cannot be said the other way around.
Its sadly not as simple as this, Greg. Modern and higher quality craftmanship also makes the energy build better in the limps, meaning it needs a lower spine to coop. But its true, it doesnt matter a whole lot for an instintive archer or if you shoot shorter distance in same weatherconditions. However it does matter for a "sighted" shooter, even if its stringwalk/facewalk or with an actual sight, if the weather changes and if shoot long distances. The reason for not mattering alot for an instinctive archery is, they get used to the flight of the arrow and compensate. Takes alot of experience with the equipment if the factors like distance or weather changes during the course. For a shooter who aims, like arrowpoint at the 11ring, you need the "true flight". As aimer you dont want to compensate. Also if the weather changes, the feather get wet. Then the flight of the arrow changes alot if your spine is wrong. I got a mate I shot up to in normal conditions. If it starts raining.. I take the gold no doubt because he didnt worry about bareshaft. Thats in 3D. On a targetface at 20 yards/18meters. Doesnt matter unless its outdoor. You should test that next time, but Im not sure YOU are able, being a good instinctive archer. Your brains gonna compensate on autopilot
Interesting I find that with modern materials people tend to use stiffer spines. A spine matters not so much in what your are doing, but at what level you are doing it at. A newer archer with inconsistent form and a large shot group, spine is not nearly as important as a skilled archer with consistent form and tight shot groups. Instinctive archers do not as a whole, have tight shot groups, that is why people use aiming methods such as GAP, Split Vision and String Walking to name the most common. I can shoot long distance, I just choose not to.
Shouldn't all spines be measured using the same distance between suspension points irregardless of arrow length? Of course an arrow measured from wider suspension points will diflect more than the same arrow measured at a narrower distance. Thanks for the video, and the explination that not all shafts are measured in the same way or by the same standards.

I fully agree they are a preference. I tend to favor a softer spine.
Ohhhhhh, Greg! So much information. 🎉

Spine is the cake; tip weight and length are the frosting, a.k.a. tuning.
