Modern bows are extremely adjustable, which permits you to tune your acquiesce your arrow and general setup. This offers you a great deal of versatility, however it can be rather frustrating when you are simply getting going. One action of tuning is to set the tiller, likewise typically called” tillering the bow”.
To comprehend how to tiller your bow, you require to comprehend what tiller height is and how the tiller works. For that reason, I will discuss in information whatever there is to learn about tillering.
What tiller height is
Tiller height is the horizontal range in between the string and the limb closest to the limb fitting. By comparing the tiller height of the upper and lower limb, you can compare the quantity of pre-tension of both limbs.
Comparing tiller heights
Looking just at the upper or lower tiller height does not state much. It’s everything about comparing the 2 measurements. In many cases, we desire the lower tiller height to be lower than the upper tiller height. This suggests that the lower limb is under more stress than the upper limb. I talk about why we do this later on in the short article.
To make this contrast, we utilize the following formula:
” tiller upper limb– tiller lower limb = tiller setting”
This formula will provide you the following outcome:
- Favorable tiller: the tiller of the upper limb is greater than the lower limb.
- Neutral tiller/no tiller: there is no distinction in between the upper and the lower limb.
- Unfavorable tiller: the tiller of the upper limb is lower than the lower limb.
Many archers shoot with a favorable tiller, however some choose a neutral tiller. In basic, shooting with an unfavorable tiller is not advised.
How to determine tiller height
A simple method to determine the tiller height is to utilize a bow square. If you do not have a bow square yet, I extremely suggest purchasing one due to the fact that you likewise require it when you are tuning your nocking points and it likewise makes it much easier to determine your brace height. I have actually purchased this bow square from Easton and general I am really delighted with the resilience.
To determine your tiller height with a bow square, you position the top of the T-shape on the limb near the riser. While holding the bow square in a straight line, you checked out off the measurement in the center of the string.
How to set up the tiller
Now you understand how to determine the tiller, it’s time to set up the tiller. Both recurve bows and substance bows have a tunable tiller. However specifically on recurve bows, it tends to be rather made complex. For that reason, I will talk about that a person initially!
To set up the tiller on a recurve bow, you should follow these actions:
1. Procedure the present tiller height: prior to you begin changing the tiller, you ought to determine the tiller height of both the upper and lower limb. Now deduct the tiller height of the lower limb from the upper limb.
2. Lookup the perfect tiller height: most producers have actually a suggested tiller height for their bows. For that reason, seek advice from the owner’s handbook to discover the perfect tiller height. If you can’t discover a suggested tiller height, you can utilize 5/32 inches (4 mm) which is typically accepted as a good tiller height. Later on in this short article, I will discuss this measurement in more information.
3. Loosen the locking bolt in the back of the riser: most recurve bows have a bolt that locks the tiller in location. Otherwise, the tiller might alter each time you keep your bow. In many cases, you loosen this bolt with a 5/32 (4 mm) hex wrench.
4. Change the tiller with a hex or your exclusive secret: on the majority of bows, you change the tiller with a hex screw incorporated into the tiller head. Turn the head clockwise to reduce the tiller height and turn the head anti-clockwise to increase the tiller height. One turn boosts or reduces the tiller height by about 3/64 of an inch (1 mm). However the real quantity varies per bow
5. Tighten up the locking bolts once both tillers are set up properly: for the most part, you can get to the advised tiller setting by changing just one tiller. However in some cases you should change both tillers in the opposite instructions. This may take a couple of shots.
- Eliminate the stress from the limbs while altering the tiller: I constantly suggest altering the tiller when the bow is unstrung, for 2 factors. The very first factor is that the turning tiller head can seriously scratch the limbs (see image). On the majority of bows, the tiller assembly can likewise be eliminated from the riser. If you mistakenly do this while changing the tiller, you can get hurt or harm your bow.
- When you have actually set up the tiller, make certain to compose both tiller heights down: because the bow vibrates a lot throughout your shots, the limb bolt may come loose every once in a while. If you have both tiller heights jotted down, you can utilize it to restore it to your old settings.
- Examine whether your limb positioning has actually altered: bows with an exclusive secret have an eccentric axle which likewise sets up the limb positioning. That’s why there is typically a marker on the limb head which assists you examine your limb positioning. If you alter the tiller, you will for that reason likewise alter your limb positioning. For additional information and a presentation, examine this short article. On these risers, I suggest very first tuning the tiller height and after that tune the limb positioning.
To alter the tiller height on a substance bow you turn the hex screw on the front of the tiller head. Turn clockwise to reduce the tiller height and anti-clockwise to increase the tiller height.
Because substance bows can’t be quickly taken apart, there are no locking screws. For that reason, it’s really uncomplicated to alter the tiller. You can likewise securely do this with your limbs under stress. On substance bows ought to be established with a neutral tiller. This suggests that the tiller on both sides ought to be the exact same.
The tiller on a substance bow ought to just be set when and examined just when you are configuring your draw weight.
As pointed out previously, a great beginning point for recurve bows is to set the tiller at 5/32 (4 mm). Whether you lower or increase the tiller depends upon your choice. I talk about how to do this in the next area.
I suggest remaining within 0 and 15/32 inches (12 mm). Having a high favorable tiller or an unfavorable tiller is not perfect for the most part. For that reason, just surpass these suggestions if you have experience and understanding of the characteristics of the tiller.
Finetuning the tiller
Among the excellent features of adjustable tillers is that you can tune them to your preference. In this area, I talk about 2 approaches on how to tune the tiller and some reasons you may wish to avoid this action in the meantime.
Technique 1: sight pin technique
The sight pin technique is typically utilized by coaches due to the fact that you can quickly tune the tiller and observe its results. However nowadays, the majority of archers believe that the 2nd technique is more perfect. The sight pin technique works as follows:
- Point the sight pin in the center of the target and draw your bow (without an arrow).
- Ensure to keep your arm unwinded while drawing the bow.
- Take a look at your sight pin and examine whether it’s beginning to wander upwards, downwards, or if it remains in location.
- If the sight pin increases you ought to increase the general tiller. If the sight pin moves down, you ought to lower the general tiller.
- Continue altering the tiller till your sight pin remains in the center throughout the draw.
This is a simple technique to utilize while finetuning the tiller, however it’s not best. For that reason, the majority of archers utilize the 2nd more contemporary technique. In addition, if you should alter the tiller beyond the advised borders from 0 to 15/32 inches (12 mm), you most likely ought to tune the nocking points rather.
Technique 2: Finger pressure technique
With this technique, you evaluate the finger pressure. Draw your acquiesce your anchor point and feel just how much pressure is put in on each finger. Is your forefinger doing all the work or does it begin to slip?
For instance, if your middle finger begins to slip, you may wish to increase the lower tiller. This decreases the force on this finger and makes it much easier to hold. This is all really individual and it’s finest to try out this to discover your perfect tiller setup.
In the video listed below, Jake Kaminski describes in more information how he sets up the tiller with this technique:
Why you may wish to avoid this action
If you are trying to find tuning guides you may begin to fall under a bunny hole. When I initially began tuning it certainly felt in this manner. There are numerous methods to finetune the bow and the general impact on the archer is typically overemphasized.
For the majority of archers, finetuning the tiller isn’t worth it. Simply set the till to the advised worth and forget it. In archery the maxim” if it ain’t broke do not repair it” certainly is true. Why would you finetune your bow if the arrows are flying directly?
For That Reason, I just suggest finetuning the tiller if you are experiencing concerns or if you have an interest in checking various settings. I think most archers would choose to invest that time on the variety rather.
Why you should set up the tiller
Tuning the tiller of your bow is essential due to the fact that this assists to adjust the quantity of force above and listed below the arrow. If the quantity of force is not equivalent arrow will fly less directly, which triggers errors in your shot.
On recurve bows, it’s advised to shoot with a favorable tiller due to the fact that the grip remains in the center of the bow. Because the arrow is shot above the grip, the arrow is more detailed to the upper limb than the lower limb. For that reason, without setting up the tiller, the upper limb would apply more power on the arrow, which triggers a disbalance.
For that reason, we lower the tiller of the lower limb. This basically increases the quantity of stress of the lower limb which makes up for this distinction.
On a substance bow, we shoot with a neutral tiller, which suggests that the upper and lower tiller is the exact same. On substance bows, the arrow is shot from the center of the bow, and the arrow is positioned listed below it. For that reason, tiller tuning is very simple on substance bows.
Why you ought to sometimes examine your tiller
Because the tiller height affects the arrows’ flight pattern, it’s a finest practice to examine it sometimes. You do not need to examine it as regularly as brace height, however I would examine it a minimum of every 3 months.
The tiller height should not alter much, however in some cases the locking screws may come loose. For that reason, constantly make certain that your tiller heads are repaired prior to you assemble your bow.
Extending of the string can likewise alter your tiller height. For that reason, when you change the brace height of your bow, you may likewise wish to examine whether your tiller height is still within appropriate margins.

Brace height– what it is and how to change it
In many cases, brace height is a set and forget element of bow tuning. If you, do it right when, you should not need to alter it, with some uncommon exceptions. I hope this short article assisted you to set up and comprehend how tiller height works.
