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
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
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.
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?
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.
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...
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
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.
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.
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.
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..?
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
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..!!!!
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?
