Cutting Arrows – Long Cut Those reasons are increased arrow weight and creating correct spine dynamics. Regarding weight, different arrow classes or models are normally presented by four sets of criteria; spine, straightness tolerance, matched weight and grain-per-inch (gpi) specs.
Why do you cut down arrows?
You cut arrows to lower the total weight. Shorter arrow equals more speed. Spine can also be changed by cutting which aids in tuning the arrow to the bow. You can also change the effect of spine by changing point weight.
Do you cut arrows to draw length?
A good rule of thumb is to cut it no shorter than the middle of the riser. At full draw, your arrow end would sit right in the middle of the shelf. The best way to determine how long you want your arrows to be is to nock a full-length, uncut arrow and draw it back.
What length should you cut your arrows?
The best safety practice is to make sure your arrows sit at least 1″ beyond your arrow rest when the bow is at full draw. A little bit of extra arrow length gives the arrows an important margin of safety. A little too long is okay. A little too short is not.
Why are arrows shorter than draw length?
Most are behind the riser slightly. So, if you cut your arrows off so they are at the front of the risr when at full draw, then they will be equal. If you cut off your arrow so it extends beyond the arrow rest 1 inch, then the arrow will always be shorter than the draw length.
How long should my arrows be for a 26 inch draw?
How to: Select the perfect arrow Bow Arrow length Draw weight lb. 25″ 26″ 15-20 700 700 20-25 700 700 25-30 700 600.
How long should my arrows be for a 29 inch draw?
it depends on the arrows you choose, you need at least 1/4″ of arrow overhang on the rest. so you can probably shoot an arrow that’s about 28 1/4 for rests that are set up normally. and go all the way up to full length 36″ arrows for indoor. i would suggest 1″ of overhang on your rest.
What length arrow do I need for 27 inch draw?
The arrow must be 29″ in length and supported by two points, which are 28″ apart. The number of inches the arrow deflects or bends due to the weight, is the spine size or measurement of an arrow. DYNAMIC spine describes the way an arrow reacts from the stored energy of a bow as it is shot.
Can an arrow be too long?
The longer the arrow, the weaker the spine. So to answer your question, yes an arrow can sometimes be too long. The spine cannot be weaken by the arrow being too long – the spine is based on the deflection of a 1.98 weight hung from the middle when suspended 28″ between two points.
Are longer or shorter arrows better?
Shorter arrows are lighter and can generally be made to be stiffer than long arrows. An arrow flexes as it flies through the air and a shorter and stiffer arrow will flex less and this also helps with additional speed and flight distance.
Is a longer arrow more accurate?
If from your bow and if a 32 inch arrow had the correct dynamic reaction vs a shorter arrow with the correct dynamic reaction then the longer will shoot better.
How do I know my draw length?
To measure your draw length, stand with your back to a wall stretching your arms out against the wall. Measure the distance from the end of your middle finger to the end of your other middle finger, basically the length of both arms, hands and chest. This measurement, minus 15 then divided by 2, is your draw length.
How long should my arrows be for a 28 draw?
If you’re a 28-inch draw length and want an arrow that ends at the front of the riser, your arrow length would be around 27 inches. However, your arrow length can be longer if you need to weaken the spine of your arrow. For safety reasons, your arrows shouldn’t be cut too short.
How does arrow length affect spine?
The longer the arrow, the weaker the spine of the arrow becomes.
How many grains is a 500 spine arrow?
Arrows with weaker spines generally weigh less than those with stiffer spines. The Gold Tip Hunter XT in a 500 spine, for example, weighs 7.3 grains per inch, while the same arrow model in a 300 spine weighs 9.3 grains per inch.
What does 400 mean on arrows?
The numbers refer to the spine of the arrow. The different spines refer to the stiffness, a 400 spine arrow is generally for bows 40-60 lbs. 350 spine is for bows roughly 55 – 75 lbs, and a 500 spine arrow is for bows roughly 30 – 50 lbs.
How do I know my draw weight?
The standard for determining their draw weight is taken at 28 inches of draw length. The draw weight is marked on the bow’s lower limb with the pound sign (#),such as 35# @ 28”. That translates to 35 pounds of draw weight at a 28-inch draw length.
Can an arrow be too long for a compound bow?
For just being too long, nothing wrong happens. If, however, by being too long, the arrow’s dynamic spine is too low, then the arrows will not be accurate as they will tend to “fishtail” in flight. They will also tend to fly to the right (for a right handed archer).
Does arrow length include Nock?
HOW DO I MEASURE CORRECT ARROW LENGTH? Correct arrow length is measured from the bottom, inside of the nock groove (deepest point where the string goes into the nock) to the cut end of the shaft, not including the point or point insert.
