The joys of being online: "Sisal, with the botanical name Agave sisalana, is a species of Agave native to southern Mexico but widely cultivated and naturalized in many other countries. It yields a stiff fibre used in making various products. The sisal fibre is traditionally used for rope and twine, and has many other uses, including: paper, cloth, wall coverings, carpets, and dartboards." Who knew dartboards came from cacti?
Here is the gist: Each individual thread is composed of fibers that are all spun together (like rope). This spiral shape means that when something pulls on the thread, each fiber is squeezed more tightly against the other fibers. This squeezing causes the friction between the independent fibers. Now, the fibers aren't all lined up, they start and stop randomly. This randomness means that where one fiber stops, another is starting, and the tension is taken by the other fibers in the area.
it's because the individual fibers are interlaced so much that the friction between them is massive. try this: take two books about the same size, and interlace them by taking the pages of one book and placing them one by one between the pages of another book (as though you were shuffling cards - search "phone book friction" if you're not sure what I'm talking about). they will be almost impossible to pull apart. ropes work under a similar principle.
Your interest is clearly in the technology of cordage. (Thread vs rope is a matter of scale). Your bias is fine. However, the technology makes *use* of friction and the huge internal surface area when small fibers are intertwined.
just think about it for a minute and picture the smallest fibres which become intertwined with each other and then the others become intertwined with them upon more and more intertwined fibers so that they are all interwoven with all their differents lengths being completely stuck together. It's the repetition of intertwining that does the trick.
@carmsbody2000 Friction. The individual strands of the rope are twisted so that they apply friction on the other strands. You can hear him at around 2:12 say that you can see the twists working against each other. If you've every twisted a string or a rubber band so much that it curls up on itself, the part that curls up is twisted in the same fashion as the rope they're making.
It'd make sense to show it - look for video on 'spinning'. Roughly: fibers are spun, the same way wool or cotton fibers are spun, into 'rope yarn'. By being twisted together, fibers lock enough to hold into a cord -called a ply- that can be twisted around several others as shown here. (Some cloth fibers are mutiple spun cords (plies) twisted together like rope - otherwise, the thing that holds cloth fibers together is the weaving or knitting preventing the spun threads -yarn- from untwisting.)

Old good technique! I'm assuming not too much people can do anything like this today, and it's really bad because it means that after couple of generations we will lose this technique.
john papple The problem is that any new technologist who specializes, for example, in rope making, will only be able to work and produce ropes (and rope is just an example could be anything else) with his modern machines and technologies. Our ancestors spent thousands of years developing this techniques and it took us 2-3 generations to forget everything that we knew and to rely completely on new machines and equipment. A quote from Gandhi: "The expert knows more and more about less and less until he knows everything about nothing."
artiyom It's kind of ironic really, the new technology killing it is also preserving it. The technique will never die so long as we have it online, via video or picture, people can do it themselves.
Would if you took those 3 of those original ropes and made that but then took 3 of the finished product and wove them together. And then do some same thing over and over
Take two phone books and interleave the pages one by one (how it looks when shuffling playing cards) then try and pull the phone books apart holding the spines, you cant.
It was the industrialization and mechanization - i.e. technology, that eliminated the need for child labor in the developed world - not government or socialism, which like to take credit for others efforts.
+David Chambers Yes and no. Check the National Archives: "The successful exploitation of child labour was vital to Britain's economic success in the 19th century. In 1821, approximately 49% of the workforce was under 20. In rural areas, children as young as five or six joined women in 'agricultural gangs' that worked in fields often a long way from their homes. Although a law against the employment of children as chimney sweeps was passed as early as 1788, young people - because of their size and agility - were still used in this role for much of the 19th century. It was also during this period that people started to recognise the importance of education for children (only a minority, mostly from the wealthy ruling class, had any kind of formal schooling at the beginning of the century). Under the Factory Act, textile factories were ordered to provide at least two hours of education daily for children under the age of 13. Towards the end of the 19th century attitudes towards children shifted further. The National Society for the Prevention of Cruelty to Children (NSPCC) was founded in 1889; and earlier, in 1870, the Education Act had brought huge changes. The Act put in place the building blocks for a free and compulsory education system. Gradually, every child in Britain was introduced to schooling. By the late 19th century, children's lives were beginning to be transformed. They were going to school instead of work, and being treated as children instead of 'little adults'. With the protection of the law, many could now avoid the exploitation of their childhood and gain an education. The case of Martha Appleton in 1859 highlights the terrible working conditions thousands of children across Britain endured every day in the 19th century. As a 13-year-old textile worker in Wigan, Martha was employed as a 'scavenger', picking up loose cotton from beneath machinery. On one particular day, Martha fainted and caught her left hand in an unguarded machine. In the accident, all her fingers were severed. Martha lost her job because she was no longer able to work efficiently. Changes came in 1833 when the *Factory Act* was passed. The Act not only created the post of factory inspector, but also made it illegal for textile factories to employ children less than 9 years of age. The Act came at a time when reformers like Richard Oastler were publicising the terrible working conditions of children, comparing the plight of child labourers to that of slaves. The timing was significant: slavery was abolished in the British empire in 1833-4. Further *legislation limiting child labour in factories* was introduced in *1844, 1847, 1850, 1853 and 1867*. After 1867 no factory or workshop could employ any child under the age of 8, and employees aged between 8 and 13 were to receive at least 10 hours of education per week. But such legislation was not foolproof. Inspectors often found it difficult to discover the exact age of young people employed in factories, and reports showed that factory owners did not always provide the hours set aside by law for education." Poverty creates desperation, and greed encourages exploitation. Love costs. Parents in the "developing" world *still* send their children to work, and still sell their children into prostitution.
"don't google friction. that tells you nothing in relation to this. friction is what holds the fibers together but not how the fibers are made into cord" wat?
Dang the old man was about to say where the siscel comes from and the narrator talks over him. Most people don't know what ropes made from.

The internet is amazing. One moment I'm looking at porn the next I'm learning how rope is made.

Thanks a lot for uploading these.
"In preparation for their trolling expedition..." .. the Brits be trollin' with rope since 1864
Excellent video on basic information. Regards,

Did I just learn how to make rope?
I think I just learned how to make rope.
wow! i had no idea making rope was such an art :)
Thanks for sharing this Technical Manual !
So can you only make a 20 yard long rope? Or is there a way to continue weaving in fibers?
Did he say trolling expedition? :)
They were planning on a fishing trip--the piscine, not the pestilential variety--as I recall.
archanth
haha I was kidding :)
lol
LOL you're pretty much everywhere on RUclips aren't you?
*****
Haha I think this rope making video is cool :)
he's got an opinel! awesome
Very interesting!! Now I know how to make rope!
What is the name of the acorn looking piece that slides inside the the 3 twisted strands?

Let see, 4.82803 km per day? That's quite a hardwork.

how do you first make the thinner strands from the short fibers
@carmsbody2000
Friction.

yeah, advancement of technology is such a bad thing. why would anybody want a more efficient, cost effective method of making rope.

Actually, we learned it in elementary school (Austria) (I went genius and used an battery drill because we used our hands in school.)

+artiyom
Normally I'd agree with you, but this same method is still used today. The only difference is that a machine does it.
What stops it from unwinding itself ?
OK but how do you make the sizel?
woow very cool, but what tipe of cordage you use in this video? thaks so much. ale
Would if you took those 3 of those original ropes and made that but then took 3 of the finished product and wove them together. And then do some same thing over and over
I went to morellem key place last weekend
У нас так делали веревку 20 лет назад.
Take two phone books and interleave the pages one by one (how it looks when shuffling playing cards) then try and pull the phone books apart holding the spines, you cant.
I can't explain it. The video plays for me. However, I occasionally encounter problems such as that.
We still do it to produce up to 50 mm rope
how much weight can that type of rope they made hold?
Look for the "rope strength" link in the "about" section below the video.
ooh ouch, just did the math dyneema is 18 times stronger than that rope, probably 18 times more money too tho lol.
Google "Chatham Historic Dockyard", and you can have both.
0:14 trolling expediton?????
how it's make english version
Ted baker looks like the captain from fort boyard
Very Riki Tiki Interesting! :)

@johnpetermalcolm cool
I love youtube.
horses are used to pull the rope
there is way of weaving fibers
"don't google friction. that tells you nothing in relation to this. friction is what holds the fibers together but not how the fibers are made into cord"
wat?
interesting
Oh! A flemish string, isn't it :D
Why would someone need rope for a trolling expedition? They can just use the internet for that.
google "friction"
First Germanicfolc....now they've terminated Zodiacza, too :((
You're projecting.
i came for the rope but stayed for the brittish
Nice to see Englishmen using English units of measure. We'll never give up miles in 'Merica!
The mask in opening scares my shxt out.
trolling expedition
I came here from "Mr President"....
Wow, you got a lot to learn about friction then, methinks you should ignore what WCherokeeW tells you and, proceed with googling friction..
If its not broke....
Dont fit it!
/watch?NR=1&v=KA9zDfYio6c (Y) ...
