This is a great article I came across a couple of years back, but which I think is still very relevant for India. Bamboo grows all over India, but is a difficult wood to work with as its shape and structure limits its usability. Here is a machine invented by a Imli Toshi north eastern India that prepares Bamboo logs for carpentry work. The machine removes the knots, does the planning and polishing of the surface of the Bamboo so as to prepare it for usage. This is a great innovation for a country that has plenty of Bamboo but little timber resources.
