How To Make Bungee Cords

Bungee cord consists of a core of elastic strands that are covered in a nylon or cotton sheath, and is commonly supplied in a wide variety of colours and weights. The majority of natural and synthetic cords tend to be knitted, braided or woven and can incorporate elements of stretch depending on end use.

Beside above,what makes a good bungee cord? Heavy-duty cords and longer options are designed to secure large items. Bungee cords can have either plastic, metal, or carabiner-style hooks or a ball at the ends. Metal or metal-core hooks are a good pick for extra security and strength. The best bungee cords are strong, durable, and keep their elasticity over time.

Things to consider

Below are some things to consider when trying to figure out how to make bungee cords.

What sizes do bungee cords come in?

Shock cord, commonly known as bungee cord, is available in a variety of diameters ranging from 1/8 inch with a tensile strength of 100 pounds to 1/2 inch with a tensile strength 450 pounds.

How many pounds can a bungee cord hold? The wider the diameter of a bungee cord, the stronger it is. A 2-millimeter cord has a tensile strength of 275 pounds. A 4-millimeter cord, on the other hand, has a tensile strength of 550 pounds.

How far can you stretch a bungee cord?

A bungee cord should never be stretched more than twice its resting length. Even with normal use, bungee cords will eventually stretch permanently, fray, or break as exposure to sun, rain, wind, and extreme temperatures can accelerate a cord’s deterioration.

How do you fasten a bungee cord? Push one end of your cut piece of shock cord through the bungee hook.

  1. Tie a Thumb Knot with the shock cord near the end to keep the cord from sliding through the bungee cord hook.
  2. Tie another Thumb Knot with the shock cord below the bungee cord hook to keep the hook from sliding along the length of your cord.

What means bungee cord? A bungee cord (sometimes spelled bungle; also known as a shock cord) is an elastic cord composed of one or more elastic strands forming a core, usually covered in a woven cotton or polypropylene sheath. Specialized bungees, such as some used in bungee jumping, may be made entirely of elastic strands.

What is the difference between shock cord and bungee cord?

According to Wikipedia they are the same thing. The one difference might be is that bungee cords normally have ends installed while this shock cord is just the cord part. Bungee cord/ shock cord is the same thing. It is a cord made of lots of thin elastic strings bound together by a woven nylon casing.

Bungee Cords

I learned on a mil. spec. system. In pirate jumping it has a number of advantages. You have a set of 5 individual cords that you group together in a set of 3,4,or5. So you can jump from 100-250lbs with one set of cords. They are covered in Nylon (or Cotton) sheaths that protect them from dirt when you lay them down. Also, the redundancy of multiple cords, as well as the sheaths which act as a static back up in the case of over elongation, provide (I believe) a greater degree of safety. Traditional mil. spec. cords have an elongation of about 110%. By the way, in the “bungy or bungee” page a common mistake is made about this word. Elongation refers to the change in length of the cord, not the ultimate loaded length. So 110% elongation in a 100 foot long cord is 110 feet for a total stretched length of 210 feet, or 2.1 times it’s original length. Since mil. spec. cord stretches less, a longer length is often used, resulting in more initial free fall.

After the 1995 X-games I realized that, because of the bigger rebounds, more acrobatic stunts were possible on all rubber cord. So I set about learning how to build that type of cord. New Zealand style cord is built with a ribbon, about 3 inches wide, composed of a number of stands of rubber. This is wrapped around teflon spools, tied together, stretched to it’s ultimate elongation and wrapped down it’s length, with the same type of rubber, to hold it all together.

The actual building of an all rubber cord, or tying loops on the ends of mil. spec. cord is not something that can be learned through words only. You need to learn first hand from someone who knows what they are doing. So you can watch them and they can check your work. The same goes for the bungee system, whether it’s a lowering system, a man basket on a winch, or a raising system, you either need to learn it first hand or start from scratch with the engineering done on all the materials, and many practice “jumps” done with sandbags.

New Zealand specification cord has an elongation of 200-300%, i.e. it will stretch to 3-4 times it’s original length. I believe the Kocklemans came up with the idea of building a length of webbing into all rubber cord. This back up is the length of the ultimate elongation of the cord. This gives it the redundancy that I like. The Kocklemans build their cords thicker than New Zealand specs. This gives the cord a long life (over 1000 jumps) but results in higher G-forces, and less ability to do rebound tricks. I believe their elongation is 150-200%.

It is difficult to determine actual elongation because many people will tell you the length of the all rubber cord before it is stretched out and tied down it’s length. This makes the cord a little longer (about 5-10%) than when the ribbon is first layed around the spools. For example, for a 100 foot jump you would first lay the rubber out at 22.5 feet, which would need to stretch to 4.5 times it’s original length to get to 100 feet. But once the cord is stretched and tied it would be about 25 feet long. So then it would need to stretch to 4 times it’s length to reach 100 feet.

Well, I’m starting to ramble so that’s all I have to say about that. Here’s some info for your bungee sites list. Total Rebound and Yesh in California are friends of mine that are no longer in the business. My company will be active again in Northern California in December 1996. I’ll update you later. The sites at Raging Waters and Big Bear were both temporary stops for Thrill Sport Productions, who produces our show in Taiwan. They will have arches at state fairs this summer in Wisconsin, Michigan, Ohio, and other places. Their Corporate office is 88 A Elm St. Hopkington MA 01748 Tel.(508)435-0420 Fax(508)435-6594. Total Hard Core Gear, in Redding California, makes what I think are the best harnesses. They make both ankle harnesses and chest and waist harnesses. They are fleece covered, well padded, and use self locking parachute buckles, which are easy to use and secure. Sorry, I don’t have their address or phone number. I used the N.Z. Bungy Knot ankle binding at the 95 X-games and didn’t like it. Like you said, you feel trapped. Also, the force is transferred to your legs with a 1 inch strap, which, even though padded, digs in after a while. The worst thing though is that when it tightens there is a 2 foot strap of webbing hanging off which can wrap around your calf on a rebound and then your are hanging from an unpadded 1 inch strap which really abrades the skin and can cause hematomas. This happened to three of my friends at the ’95 Extreme Games.

The Euro Cord

The European/New Zealand cords described above look like this

Read Post  Bungee jumping facts for kids

Steve who wrote that section above believes that the US mil spec system is safer because of the extra redundancy, but the Euro cords do have the advantage that they can be inspected after each jump for signs of rubber failure or possible problems. The sheath on Mil spec cords prevents this. Some Euro cords have an extra static line built into the core to prevent over stretch and provide extra backup. The term Euro cord is a little misleading – this cord is used and made in many countries.

Mil Spec Cord

Mil Spec cord is cord that is made to US military specifications, these specifications were designed to hold down tanks on boats and in planes rather than to suspend adrenaline junkies jumping off bridges. As it turns out they work rather well for both!.

Picture of Mil Spec Cord

Here is some mil. spec cord made by Glenn from Bungee Experience. The pink/white stuff is the cord, the blue webbing is attached in a very special way to the ends of the cords so that carrabiners can be attached to each end. The way the end of the cord is connected with a piece of webbing is called termination. The Red Tape is part of the special way the cords are terminated.


Lots + lots of people have asked me for bungee cords specs and I just got emailed this from J Kockelman (cheers!)

Most Bungee Jumping Cord is made from “natural rubber” whose physical constants are in most college libraries. The most common bungee cords stretch 2 to 4 times the original length and the jumper feels 2.5 to 3.5 G’s.

I found a page on (link expired) which had a technical paper on Bungee jumping.
