It impresses me that your bellows has worked all these years without appearing to need repair or replacement. You can go months without needing it, but when you sit down it's ready to serve. When you originally made it I hadn't yet learned that Duong always knows what he's doing, and I thought the design was silly. I have since learned better, but this bellows is a particularly strong example of how wrong I was.

Your seed separator and the gears which make both pieces of round wood spin at the same time is genius engineering. What you do with the harvested rubber will be very interesting. All the best for the coming New Year.

I really like this channel one of true primitive channels everything He does feel genuine and in every video there is something new to learn from him.

You can do a proffesional paints from such latex rubber. You just need to add some fillers such as limestone and dyes. If you want to prepare a black vulcanized rubber then you need to add sulfur to white latex rubber. This vulcanization is usually carried out by mixing crushed rhombic sulfur with rubber, and the obtained paste is applied to hard pressure rollers called calenders, where the previously mentioned cross-linking reaction takes place at a temperature of approximately 150 °C. Depending on the vulcanization conditions, the type of rubber used and the sulfur to rubber ratio, harder or softer types of rubber can be obtained. The higher the cross-linking density of the rubber, the less flexible (harder) and slower the rubber wears.

I have a high respect with this guy. Very primitive way harvesting the mother nature's gift wow 😮

Theoretically, you should be able to use rubber to make rubber bands (rubber circles) and use those in more complex machinery. Now, I am not very knowledgeable when it comes to machines, mechanics, but you should be able to use rubber bands to store kinetic energy and release it to make certain jobs easier. Rubber bands can be used instead of rope, to hold things together. Rubber string can be used in the same way. You can also try to use the rubber to waterproof your tools, clothes, spaces, buckets, small cracks. Rubber also helps you grip onto things easier, so you could either make rubber gloves, or coat your tools in rubber to prevent your hands from slipping while holding onto them. I think rubber can melt if you expose it to high temperatures, which should make it easier for you to create different rubber shapes (cast rubber) or coat things with rubber. You can also make rubber molds. I think that Concrete doesn't stick to rubber, so you could make LOTS of concrete bowls or cups VERY quickly if you have the right rubber mold made. You could also use rubber to trap air. (I don't know what that can be used for, but I think an engineering/your mind could make use of this). You know Rubber Balloons? You could make those with the rubber you had made and maybe there could be a use for this? Could use rubber balloons to cast concrete bowls out of them. When the rubber is still liquid, you can actually color it too. Could make black rubber, brown rubber, green rubber if you want for more colors. You could make a long rubber string and add it to your forge fire air tube blower.. thing (not sure what to call it). You know, that thing that makes your fire grow bigger and stronger when you push air into it? You can use the rubber string, so that the fire blower handle will slide back into place on its own, without you having to push on the handle. Or, you could use rubber to make a fireplace bellows. It's another, alternative way to blow air into your fire.

Merry Christmas, Duong! Your projects on the homestead are truly wonderful to watch and I hope you have a lovely rest of your year!

Impressive! If you impregnate fabric with latex you will get an excellent waterproof material. It would be very interesting to see a water pump made from latex valves and latex fabric hoses; Latex also makes excellent bottle caps.

Always amazed at how sharp he can get these tools he makes

Make a cloth bag with only a small hole at one end. Then fill it full of soil. Now paint it with latex, allowing it to dry each time. Repeat this until the latex is thick enough. Now empty the soil out. Now you have an airtight bag for the bellows! You could make the bag in a triangular shape, and put wood over and under it to protect the latex. Like a traditional European bellows. You could also make a Rucksack that is totally waterproof!

I have been enjoying your channel for years and this is one of those videos that leaves me speechless. You are truly the most talented person on RU-vid. No one else does the primitive things that you do. Not even the original primitive dude. If I am ever in a plan crash and stranded in the forest, I hope it is near your farm. It is the only way I would be guaranteed to survive.😄👍💪🏼

Hi Duong, Looking forward to see what you're going to do with the rubber. Cheers from France ❤

Duong, this is amazing. Maybe next time, instead of leaving all the liquid latex to harden in the deep bucket, pour thin layers into shallow winnowing baskets and let it harden in thin sheets. Less cutting and much less pressing required. You are amazing. Thanks for sharing.

I remember the day you used bamboo to bring water down from the mountain, there was a fire and a roof, not much else. Thank you for sharing

Beautiful work as always! Happy new year!

These are the only videos that I really enjoy watching. Using all the primitive and ancient techniques remind me the survival history of humankind. Thank you my friend tak tak. Best wishes from Istanbul.

Acho incrível suas habilidades 😊😊 parabéns por ser tão guerreiro. Estou a produzir alguns conteúdos meio que parecido. Mas sei que não chegará aos seus pés.

Super! Danke!😍🤗

Seus vídeos são tão maravilhosos, eu realmente relaxo assistindo. Obrigada por fazer os vídeos. Desejo que sua vida seja longa e próspera!

Thank you for sharing your skills and and knowledge. God bless you and your loved ones

You never cease to amaze me…what a creative mind.❤

Hello Mr. Duong, your videos are very good, you are a creative person and I really like everything you do. ❤❤❤❤❤❤

so sad to see your waterwheel broken... is there any plan to restore it in the future?

(11:20) Nghĩ lại, khi tôi còn trẻ ở Indonesia, tôi chưa bao giờ xem ai làm việc trên cây ở đồn điền cao su nơi bố tôi làm quản lý bảo trì! Thậm chí không một lần trong 10 năm đó! Vì vậy, hình dạng của con dao mà những người công nhân chắc hẳn đã sử dụng là một điều hoàn toàn bất ngờ đối với tôi! Vì vậy tôi cảm ơn bạn rất nhiều, Dương!😁😁😁 (11:20) Thinking back to when I was young in Indonesia, I never watched anyone working on the trees at the rubber plantation where my father worked as a maintenance manager! Not even once in those 10 years! So the shape of the knife the workers must have used was a complete surprise to me! So I thank you deeply, Duong!😁😁😁

(35:20) Xin thứ lỗi cho tôi, Dương, vì tôi chưa bao giờ quan tâm đến lĩnh vực cao su thực sự của các đồn điền cao su. Tôi quan tâm nhiều hơn đến khía cạnh cơ khí của máy kéo mà cha tôi quản lý việc bảo trì. Cộng với xe lửa mô hình điện và thiết bị điện tử của radio ống, v.v. Vì vậy, tôi rất biết ơn khi được cùng bạn tìm hiểu về mặt mủ của toàn bộ quy trình cao su!🤓😄 (35:20) Please forgive me, Duong, for never having been interested in the actual rubber side of the rubber plantations. I was more interested in the mechanical side of the tractors that my father managed maintenance of. Plus electrical model trains and the electronics of tube radios and such. So I am very grateful to learn with you the latex side of the whole rubber process!🤓😄

This guy is very organize and very talented i really admire for sll your doings keep it up bro God Bless you and your family

@PrimitiveSkillsNet did u add anything to the plant latex? Like formic acid? Thanks

Awesome and very fascinating.

Excelente. Usted y su esposa hacen cosas muy lindas para ayudar a personas de bajos recursos económicos. Dios los ha de bendecir siempre..

nice and very interresting video i hope next one will be for what you use this latex

Of course the forbidden milk gets turned into the forbidden mozzarella.

This is what i have been waiting.

also, there is something you may be able to do to the rubber called vulcanization, which may improve it's properties, though frankly I don't know if it works on latex. theoretically, if you heat the rubber with sulfur in a air-free environment (maybe a clay capsule with a tiny hole so it doesn't explode when heated) it will get firmer, but that is a naïve simplification of a process I don't fully understand

Its amazing !! 😃😃👏👏

Hello Duong! 👋🇨🇦 Wow this was a very interesting video, thank you for sharing! Can’t wait to see what you do with the rubber now! 😊

How long does it take for the trees to recover from the cuts? How often can you get the sap from the same tree?

This is another amazing video. You can do so much with rubber. It is fantastic you are helping kids. Any mention of the lake not being full? How is the upland where empty rice was? Have a Happy New Year

Once again Doung you've out done yourself 👏🏾

Is it Just me who came back from night shift work and watched this video before sleep 🛌 #much love from north east India 🇮🇳 #happy new year ❤

C est génial ce que vous faîtes, c est vraiment super avec bien sur beaucoup de travail. Je vous trouve super, un bon bricoleur et ingénieux . Muriel de France

@ primitive Skills - Make your own rubber soled shoes! Or rubber sandals. Fun stuff. You come up with fun content and have good skills.

Greetings from Ontario Canada Wishing you and your family a very Happy New Year. All the best for 2024 Thank you for all the wonderful videos Have been watching your channel for several years

Good job man 👍 ... I hope you have a good day Am frim jordan 🇯🇴😘🇯🇴😘👍👍

Cool video!

God has blessed you with many gifts and wisdom. I cant wait to see what you make with the rubber sir!

Спасибо! Весьма познавательно!

I’m just curious, is there anything you can’t do? 😂😂😂 Amazing buddy.

even trees bleed. This entire planet is one living creature

Here in Thailand the trees are cut higher up the trunk, at the lowest point of the cut pegs are driven in to give the sap a point to drain into the collection cup which here is a half of a coconut husk ! Latex is losing its value against synthetic rubber so it’s losing popularity with land owners

Oi Duong, boa tatde! Moro na Amazônia Brasileira. Já tivemis um chamado ciclo da borracha. Assistindo a esse video, lembrei-me dos seringueiros da Amazônia. Muito bom o seu trabalho, bem primitivo, não passou pela defumação Feliz Ano Novo para você e sua família🎉🎯

Great video

¡Hi Duong! Depending on what you want to make, you better make molds. You work wood very well.

You are great 👍 x

Wow...amazing...now you can manufacture a shoe right...👍👍👍

What will you be using the rubber for?

Да, слава Богу! С Рождеством Христовым!😊

Latex rubber is most easily handled if allowed to dry in thin sheets .. A large mass of latex is good for some things but may be more useful if allowed to dry on a large surface in thin sheets . I dont know how it would work out though since its going to stick to everything it drys on . Still its great to see you constantly innovating new materials and methods 🤠

My man is making sneakers in primitive technology. What a legend

Hope you're doing well my friend.

Have a good and healthy New Year, Duong!

Will you Vulcanize it with sulphur and carbon black and then heat it in an iron press to make shapes?

i know it's not a priority, but with rubber you can definitely make better wheels. so might be able to make something like a bicycle =) another fine video and hope things go well for you. edit: you'll need sulfur as well to process the rubber won't you?

My question after years of watching is how you get the cameras to move like that wile your walking 😮

Great video 👍👌

Damn doung, you're amazing. whats the step? (Suggestion: gunpowder and flintlocks)

you have any sulphur deposits nearvy? if you cook the latex with it, it becomes moldable/shapable and then can make shoes or other perminant rubber things.

(31:20) Bây giờ tôi bắt đầu nhận ra tại sao mỗi đồn điền lại khá lớn. Thêm vào đó, sau một thời gian, bộ sưu tập mủ cao su đã giảm dần về mức gần như bằng 0. Điều này đòi hỏi phải chuyển việc thu hoạch sang đồn điền mới với cây mới. Và các đồn điền được trồng lại theo chu kỳ 2 (đến 3?) năm. (31:20) Now I begin to realize why each of the plantations was quite large. Plus that the latex collection faded to near-zero after some time. Which required moving the harvesting to a new plantation with new trees. And that the plantations were re-planted in a cycle of 2 (to 3?) years.

Thank you , Duong . 🐺Loupis Canis .

Muito bom ! Aproveitar os recursos da natureza é muito importante! Pra retirar o látex, vc precisa cortar só de um lado, fazendo uma linha vertical e varias na horizontal, como se fosse uma espinha de peixe! Do jeito que está fazendo, vc vai bloquear o fluxo da seiva!

Chúc bạn nghỉ lễ vui vẻ, tôi đề xuất một gợi ý, hãy tìm những cành giâm hoặc phân lớp không khí của cây và trồng chúng để bạn có một ít ở gốc và bằng cách đó bạn không phải di chuyển nhiều.

Great❤❤🎉🎉

هذا مثير جدا للاهتمام لم ارى شجرة مطاط من قبل شكرا لك صديقي على هذا الفديو انتضر الفديو القادم حتى اتعلم منك ماذا يصنع من المطاط اتابعك من العراق 🇮🇶🇮🇶🇮🇶

What do you make with the rubber? Footwear? Raincoats? Etc?

A car engine has what is called a serpentine belt to turn the pullies so the engine can work. A bike has a chain. I wonder if you can make a rubber-pully mechanism to help you with your daily needs. Make like a bike to turn wheels or a complex pully structure to power your house more efficiently.

Bro, I am seeing you there, because I feeling myself there, you are living like anything, Enjoy the life

I will always watch you and your husbands video. I started watching your video when your husband was sick. Then I subscribed to your wife’s channel don’t stop helping the children.

awesome! time to upgrade your shoes with the new rubber 😎and maybe you can also try a slingshot?

Do you have to mix rubber tree sap with vinegar in order to transform the Latex from a liquid state into a solid state.

I recommend you to make an anvil. You can make one that is basically a really big nail that you can punch into a log and use the flat head of the nail as a striking surface to forge. Because you are striking against metal, it will retain a lot more force and heat so shaping the iron will be more easy than on rock.

Hoàng de verdad eres un pozo de sabiduría,hoy me gustó mucho saber de donde sacan el látex que usamos cada día,nunca me imaginé que pudiera ser de un árbol???? Un vídeo precioso.👏👏👏👏👏👏👏👏👏👏

I look forward to seeing what you make from this. I never fail to learn something from you from your videos, so thank you 😊

Wow good

That is fascinating. If i Imagine that my Latexcatsuit is made of this... The Rubberblob looks a little bit like mozarella😄

I wonder if mixing in some soot particles (like carbon black) would increase the UV resistance of the rubber?

Very interesting

I think that somthing called a "spile" desired for gathering tree sap from maple trees would be useful for extracting rubber from rubber trees.

Hola amigo. ¿Cuál es el uso para ese látex que usted preparó. ¿Saludos cordiales desde Costa Rica

(37:27) Ấn tượng của tôi là các con lăn ép hết nước, vâng. Nhưng kích thước tổng thể không tăng nhiều như độ dày cuối cùng cho thấy. Các tấm cao su cuối cùng có vẻ được nén nhiều hơn so với khi ở trạng thái ban đầu. Bạn có đồng ý với suy nghĩ đó không? (37:27) My impression is that the rollers squeeze out the water, yes. But the overall size is not increased as much as the final thickness suggests. The final latex sheets seem more COMPRESSED than when in their original state. Would you agree with that thought?

wow you made it to the medival era alone

How do you stop it from coming out the bottom of the bamboo poles

Steel, copper, rubber, wood, stone, ceramic, and cement - you could make your own hydroelectric power plant at this point ;-)

你好你好聰明太棒了❤❤

Make a pair of rubber shoe. Im eagerly waiting in your next video. ❤❤

Hey boss!...do you make the charcoal yourself?...if you do I would love to see a video😊

in the future straining them with cloth should help to get rid of the bits of bark and leaves so you don't have to do it by hand...

I read somewhere that aztecs and mayans in south america used to press the tree sap into clothing to give it water proofing. There is probably hundreds of uses just for the sap alone.

Good job

In Russia, birch sap is harvested in spring in April and May, it is delicious and healthy, and in order not to injure the bark of the tree, some tricks are used. You need to take a 5mm drill bit and make a small hole in the tree, then insert a cocktail tube into it. The juice will run through a tube into your container, while the tree is not injured in any way and in this way you can collect a lot of juice. 😉

The small knife for the rubber trees reminded me of a crooked knife used for wood carving. Their blades are bent in a smooth curve instead of at a sharp angle to make a blade shaped like the letter J. They are excellent for hollowing wood for making spoons or cups.
