How to bend straight bamboo into a curve. Video by Gib Cooper. Originated in Mexico. BAMBOODIRECT.COM by Gib Cooper Bambusero: Victor Martinez Assistant Bambusero: David Martinez
I think the back splits happen because he is only heating on the inside or belly, the side under compression. If you look at the failure in the picture it occurs on the outside or back, the side under tension. IMHO, if you applied the heat more evenly and particularly on the far side some of the excess tension will be released. However if you into bow making then you will not want to loose the tension in the back of your bow. In this case during the heating and forming process you only want to release just enough tension so the bow will not fail when fired.
It would be useful to find out what Victor is getting the surface of the culm to, temperature-wise. If the culm would not dry out too much, putting it into a large solar kiln with an elastic forming jig and curve the culm more slowly. No danger of charring, and perhaps fewer failures since the temperature would be more uniform, not focused only on the inside of the radius.
Pablo Dal Monte the operative words are, located warming, if you boil the entire piece you dont have control of the bending, you need to make soft the exact spot where you make the bend, the steam or boil process is useful for make flat decks
ISAK ARIEL le colocan adentro de la caña de bambú arena por eso primero le quita los tabiques q la caña tiene por dentro con ese hierro redondo que le pasa por dentro , tal cual se hace como cuando doblas un tubo de metal, q se le pone arena seca ( para que no se apelmaze y corra mejor adentro del tubo de metal ) y así cuando doblas el tubo no se abolla y /o aplasta.
We could use a rocket stove to heat the bamboo. The fuel would be dried bamboo. I use dried bamboo all the time in rocket stoves and mass heaters (if you use a "J" tube, it's even gravity fed)!
Hey Alexander. I have often thought bamboo offcuts would be an ideal fuel for a rocket stove. Do you have any links to a favourite design? I have a small bamboo finca in Panama and would love to build one.
Very labour intensive and expensive to just bend a single piece of Bamboo! There has to be a quicker way of doing this, maybe by steaming a bundle all together in some sort of container and then bending them?
Embuste, todo bambu entorta desde que esteja verde, essa técnica é bem rudimentar, hoje existem técnicas mais avançadas. O bambu ao ser dobrado só lasca se estiver machucado ou como um pré corte. Tente o cozimento, é uma técnica que mantém a cor original da fibra.
El hombre creativo procura hacer las cozas lo mejor posible - el flojo siempre quiere trabajar menos - los muebles de bambu son una manera ecologica y barata para el consumo urbano
That's not the way bamboo grows...it grows too fast for that.. On the other hand they use box forms on sides to make bamboo grow square as it gets bigger diameter ... Lateral growth would be too fast to make much difference. Maybe a little..?
That was AMAZING..!! Thank you for sharing this video on how to do this. I'm building a tiki hut out of bamboo and definitely needed to see how this "bending technique" is accomplished. Thanks, again..!!!!
Labor intensive isn't this? How about we use the sand method and get pvc pipe that is wide enough to accomodate three of this diameter bamboo, cap the end of the pvc with small drip holes at the bottome for condensation and excess steam and hook it up to a little electric steamer or use gas stove to generate steam. Seems more practical.
Esuper1 it binds form faster than traditional woods like cedar.. Even with hardwoods like teak, mahogany or even oak, it takes a long time to steam because of thickness.... Dunno how it would be with the set time of bamboo...
Guru of Random is green bamboo, if you use a dry pne you need to soak it in water one die for make fibers wet and elastic again, thats why it looks shiny in the first heat
How stiff is the bent bamboo after it is bent? I would like to use this in the course of making a recumbent bike frame. Also I assume you have to start with green bamboo?
@wingituk The bamboo should be around 2 " or smaller. As it gets larger it gets more difficult.
Víctor gracias. La idea es hacer cuadernas de una canoa

excellente, gracias. muy bueno. This is an excellent video that rally shows how to work bamboo.

Gracias Victor x compartir la técnica , quisiera saber k tipo de bambu x favor
El bambú es Phyllostachys bambusoides.
Una pregunta,como saber cuanto doblar para siertas curvas
Martinez numero uno
You are great
What about boiling it or steaming it ? that usually works with wood. Would it spoil the bamboo?
Pablo Dal Monte the operative words are, located warming, if you boil the entire piece you dont have control of the bending, you need to make soft the exact spot where you make the bend, the steam or boil process is useful for make flat decks
una pregunta que utilisas para dovlarla que le echas adentro te loagrafeseria si me pasase el tips
+Isak ariel Venturaramos arena
ISAK ARIEL le colocan adentro de la caña de bambú arena por eso primero le quita los tabiques q la caña tiene por dentro con ese hierro redondo que le pasa por dentro , tal cual se hace como cuando doblas un tubo de metal, q se le pone arena seca ( para que no se apelmaze y corra mejor adentro del tubo de metal ) y así cuando doblas el tubo no se abolla y /o aplasta.
would it work with a jig?
You can make a jig to bend out standard curve.
Sir please explain if you have easy way to bend bamboo

Ivo Bass o meu bambu já nasceu torto. Só fica reto quando enfio no buraco. De preferência no cu dia outros
que es lo que le echa al boambu maestro ? y gran trabajo
Arena
Oh, and also. When bending bamboo - does it have to be fresh bamboo or a set of canes that have sat around for awhile?
Fresh is more flexible
ok thank now if you make a jig could use bigger size of bamboo as you make it larger?
C est bien mais au prix du gaz c'est illusoire désormais.
La technique de petites découpes en " V" est plus rapide et gratuite✌

i know this is 9 years old but what's the purpose of filling it with sand?
oh, never mind
wouldn`t ya be able to start the shape of the bend you want when it is a young bamboo plant thus and let it grow into the bent shape ya wanted?
***** it seems to me really innovative, should be tried
yeah..I was thinking it would be fun to grow a house
hahahah
I`m serious...LOL

البامبو شجر ممتاز لكل اعمال الادوات المنزلية والمكاتب والمدارس وكثير جدا غير ذالك
The professor would have worshiped you
Why fill with sand? I don't understand
That's an insane amount of work and propane just to bend a stick.
THANK YOU ...VERY INFORMATIVE
I hope he doesn't get too close to the propane?

Lindo trabajo pero el miedo fue más fuerte el sopleteando alado el tanque y la manguera
Is more insane your car. Or do you walk to work?
Do they start w/ green or dried bamboo?
SuperBardley Victor started with green Bamboo.
es un vuen trabajo
I have seen this done in 3 minutes.
This is the same method for bending steel pipe.
You need to see my vlog of how it's done here in the Philippines, it's slightly different to this!
link?
How does the bamboo not catch on fire?
Guru of Random is green bamboo, if you use a dry pne you need to soak it in water one die for make fibers wet and elastic again, thats why it looks shiny in the first heat
It might be wise to edit out several minutes of things like tapping the sand down...
que tipo de gas usa?
gas propano
disculpa para que la arena porque le llenas de arena
sin la arena de daña, se aplasta
maybe a funnel would work

c siebester bamboo is HARD AS FUCK. It's been compared to steel in regards to tensile strength.
Watch videos on how difficult it is to break bamboo
Debe haber un método más sencillo, rápido y económico...
This is too long to bend a bamboo any body have easy way in less time to bend a bamboo please explain me
Maduro antes era artesano de bamboo , Maduro was
It is still very stiff.
wow
People here just heat it on a wood fire. I use a paint stripper.
Over hot coals.
BAMBOODIRECT I hope you realise you are just making random comments and not replying to individual comments
the important question is why is he wearing such nice pants while working?
Porquè es el hefe, the boss lol
that is very very expensive
what are product use under bamboo bending\
a garrafa de gas teria que está atrás do operador e não na frente do fogo tudo errado.
Comete un trozo lenguon
Need expert men to band this.
nice yob bravo-croatia -.
It would be LOT easier to boil the bamboo in hot water and then bend it.
+Mike Martin For how long?
+Mike Martin That is how it was done in its heyday of furniture making.
Make us a video like Gib did Mike Martin.. show us YOU know what you're talking about. Thank you.
@@cleenton ?. That's basic grade school science knowledge... why would you need a video for that?
I'm at 5:49, I'm so bored I'm going to kill myself (take that damn rattle away from him!).....good info on bending bamboo:)
見事です good
I don't own a car. I ride my bicycle to work... Nice try, though!
too much expensite in this time ...
er
professor girafales
looks like it comes out to 35 cents an hour. about as cost effective as the government.
