Building a Trebuchet - Seeking Advice on Slings

In summary, building a trebuchet requires careful consideration of the sling mechanism, as it plays a crucial role in the weapon's accuracy and power. It is important to choose a durable and flexible material for the sling, as well as to carefully adjust its length and weight to achieve the desired trajectory. Seeking advice from experienced builders and experimenting with different sling designs can greatly improve the performance of a trebuchet.

hey all,
im building a trebuchet and i wanted a litte advice on slings. my trebuchet is about 7 feet tall with a 12 foot arm; i wanted to know if anyone had experience in trebuchets and if they could help me with the sling, or direct me to somewhere with that info. thanks

what exactly do you want to know?

usually the length of the sling is about the same length as the arm. do you know how to set up a trigger?

Sling Length

Did you ever get your sling length figured out?

A program to help you out

Nice start you got there. Having been involved in two trebuchet projects (my brother did the work, I just advised on the physics parts), I noticed three things are important.

1) The sling release mechanism: A ring that slides off a bent nail is easy and works well. The angle of the bent nail matters.

2) Structural integrity: From your picture, if that's only a 2x4 on the arm... how much weight are you planning on putting in the box? Also, what is that pivot beam made of?

3) Weight and length ratios: Check out the website below for optimal parameters.


This website, http://www.algobeautytreb.com/" , is by far the best site I've found. It even includes a computer program to model your trebuchet and help you figure out the optimal sling length. Very helpful.

Related to Building a Trebuchet - Seeking Advice on Slings

1. What material is best for the sling of a trebuchet?

The most commonly used material for the sling of a trebuchet is leather, as it is strong and durable. However, canvas, rope, or even metal chains can also be used.

2. How long should the sling be?

The length of the sling is dependent on the size of the trebuchet. Generally, the sling should be 2-3 times the length of the throwing arm. It is important to test and adjust the length to achieve the desired distance and accuracy.

3. How do I attach the sling to the throwing arm?

The sling can be attached to the throwing arm using a simple knot or by using a sling hook. The sling should be securely attached to the throwing arm to ensure it does not come loose during use.

4. What is the best way to test and adjust the sling?

The best way to test and adjust the sling is through trial and error. Start with a shorter sling and gradually increase the length to see how it affects the distance and accuracy of the trebuchet's throw. Keep testing and adjusting until the desired results are achieved.

5. Are there any safety precautions I should take when using a trebuchet with a sling?

Yes, it is important to always follow proper safety measures when using a trebuchet with a sling. Make sure all bystanders are at a safe distance and wear protective gear, such as gloves and goggles, when operating the trebuchet. It is also important to regularly check the trebuchet for any wear and tear and make necessary repairs or replacements to ensure safe use.
