Helpful Guide To Bare Shaft Tuning: What You Need To Know

Helpful Guide to Bare Shaft Tuning

New archers often experience problems with an arrow flight. Since every archer wants to shoot consistently accurately. One of the things they must learn is how to bare shaft tune is their bow. Correcting flight issues by knowing how to tune is necessary, as this process helps you match your bow choice with the right arrows.

As a new archer, you should understand what a bare shaft tuning is, why you need to do it, how to do it properly, and how to make the proper adjustments to get things shooting correctly.

Welcome to your guide through preps for hunting! The goal in this article is for you to know the importance of knowing bare shaft tuning.

The term “bare shaft” refers to a shaft without any type of bushing or sleeve. The whole length of the shaft is to exposed. It has a larger contact area with a bearing, which results to a better heat that will transfer a less friction. This allows for a faster acceleration and a smoother power delivery.

Bare Shaft Tuning, also referred to as “BST,” is a tuning technique that uses the entire length of a shaft without any kind of bushing or sleeve.

Bare shaft tuning examines how the arrow is flying out of your bow. It’s a method that allows you to see an actual true flight path of an arrow. Making these tuning adjustments also helps you to fine-tune the bow.

Bare shaft tuning is a method for tuning an arrow. By comparing the impact points of regular field tipped, fletched arrows and unlatched the arrows. The ultimate goal of a bare shaft tuning is to have both arrows to be impacted.

Bare Shaft Tuning is becoming more popular in the modern archery world. It offers more flexibility in regards to arrow designs and performance. The downside of this style of tuning is that it’s harder for an archer to keep their arrows in tune. They have no protection against weather and wear.

Do you need to bare shaft tune?

A shaft tune is a process that involves the adjustment of the propeller blade angles in order to maximize thrust. This process is usually carried out by an experienced airman, who has undergone training and certification.

In most cases, a shaft tune will be required when the propeller blades are not set at the right angle. This may happen if there has been damage to the blades or if they have become misaligned after an accident.

In some cases, a shaft tune may not be required if there are no problems with the propeller blades but it may still be a good idea to carry out this maintenance procedure as part of regular aircraft maintenance.

What is the tuning distance for bare shaft?

The tuning distance for a bare shaft is the distance from the outer edge of the propeller to the centre of its hub.

This is measured in millimetres and it will vary depending on the size and type of propeller you are using.

The tuning distance for a bare shaft is important because it tells you how far away from your boat that you need to be when you are turning, if you want to avoid contact with your prop.

How do you tune a compound bare shaft?

Tuning a compound bare shaft is not as difficult as it sounds. This article will help you understand the basics of tuning a compound bare shaft.

The first thing to do is to remove the string from the bow. You can see that there are some small holes on each limb, these holes are called nocks and they hold the string in place. The string is threaded through these holes in both limbs and then tied on either side of your bowstring loop (the leather piece) at the end of your bowstring.

The next step is to decide which limb needs more tuning, this can be done by looking at how much the limbs are bending after you have pulled back on them, if one limb bends more than the other then that means that it needs more tuning than the other limb.

How to Bare Shaft Tune your Bow?

Bare shaft tuning is a setting of your arrow rests to improve the hit. The arrow rest adjustment is made after you notice the tear marks on the target. Bare shaft tuning is not also difficult to perform. It’s a straightforward process that allows you to use your bow to the best of its abilities. The procedure requires not just making an adjustments.

It also makes your arrow shoot at different distances. Learning exactly how the arrow is flight. The mark indicates when the arrow hit the target at an angle. You will also have to observe, if the arrow bent on the right or left before impacting the target. This tear will determines whether the arrow rest has need to be move right, left, up, or down.

Here are the steps to bare shaft tune your bow:


To make a bare shaft, remove the fletching from one arrow with a sharp knife. If you want the best possible tuning results, weigh your fletching and then weigh an equal amount of painter’s tape. Then wrap the painter’s tape onto the shaft where your fletching would attach.


Shoot your bare shaft and three fletched arrows at about 10 yards. Do your best to execute good shots, especially with the bare shaft. Fletched arrows are much more forgiving of small release errors.


Note where your bare shaft hits the target in relation to the fletched arrows. For a right-handed archer, if the bare shaft hits left of your arrows, your shaft spine is too stiff. If the bare shaft hits to the right, its spine is weak.

If you shoot left-handed, a bare-shaft impact to the left means its spine is weak. A right impact means its spine is stiff.

If your bare shaft hits low, your nocking point is too high. If your bare shaft hits high, your nocking point is too low.


Your first adjustment is to get your bare shaft’s impact point on the same horizontal plane as your arrows. Barely change your nocking point and shoot your arrows again to check the adjustment. Make changes in small increments and keep checking the result.

Once the bare shaft consistently hits on the same horizontal plane as your fletched arrows, begin correcting the left or right impact point.

If your arrow spine is too stiff, the easiest way to weaken the spine is to increase the point’s weight. You can also weaken the spine by increasing your draw weight, shooting longer arrows, or buying arrows with a weaker spine.

If your arrow spine is weak, you can decrease its point weight, shorten the arrow by a ¼-inch, decrease your draw weight, or buy arrows with a stiffer spine. As with the nocking point, make these adjustments in small increments.


Shoot your bare shafts and fletched arrows at 10 yards. If your bare shaft groups with your arrows, step back to 15 yards and shoot again. Continue bare-shaft tuning until you reach the distance where you no longer get consistent bare-shaft impacts. The farther back you go, the smaller the changes you’ll need to move the bare shaft into your fletched group.

If you hit a snag while bare-shaft tuning, revisit the archery shop. The shop’s pro can provide excellent help throughout the process.

How to Bare Shaft Tune a Compound Bow

The bare shaft tune is one of the most important aspects of a compound bow. It determines how well your arrows fly and how much they will be affected by wind or other elements.

To start bare shaft tuning your compound bow, you’ll need to prepare the following:

  1. Your compound bow.
  2. Two unfletched and four fletched arrows. The arrows that you’re going to use must have the exact same spine, length, weight and nocks, and fletchings (for the fletched arrows).
  3. Bag target or bag foam.
  4. Once you have prepared all the items that you need, you may start by shooting four fletched arrows then followed by two unfletched arrows at the bag target at 20 yards.

Once you have prepared all the items that you need, you may start by shooting four fletched arrows then followed by two unfletched arrows at the bag target at 20 yards.

It’s recommended to use a bag target when doing bare shaft tuning to avoid the arrow from getting bent during contact.



Bare shaft tuning is ideal when it comes to matching your bow with the right arrows. The method of doing it isn’t that difficult to do. It doesn’t take long to perform and making this a must-do process for all archers.

Be sure to carefully follow all of the above guidelines and take notes if necessary. Once you’ve properly tuned your bow, you can expect your consistency and accuracy to improve drastically.
