A tree is one of those sources of land which provide wood which is used as shelter in the shape of houses, fruits in the form of food, shade in the sunlight, generate oxygen and absorb carbon dioxide. Apart from all these virtuous features, wood has been a truly enriched source that helps in the development of any nation. However wood characteristics and usage depend on its quality which varies from area to area and kind to kind. Different kinds of woods have been used lately in the production of different things. From the ancient times, improvising to make new things has become a custom. This custom enhances the span of thinking and made people believe that everything which can be imagined can surely be created!
This innovation leads to the ideas that how the wood can be used. Woods kept using in the form of boards, bars, round sticks, but was that the end? Was there anything new that still needed to be discovered? Or was every invention was just a mixture of these sticks, bars, and boards or in those shapes in which it was extracted from the trees. All these questions broke down by one technique named “wood bending”. Until now a lot of techniques have been developed for wood bending but let us have a look at the three most basic techniques named steam bending, laminating and Kerf-cutting method.
Wood Bending by Using Steam
The very first method for wood bending is by using steam, it has a simple phenomenon in which the steam makes the wood ripe for bending i-e the steam or the boiling water makes the wood flexible due to which it can be curved to any desired shape and when it cools it can retain that shape. However, steaming is an easy way for wood bending but still it needs a proper apparatus comprises of a steamer, and a box in which the wood should be placed to become pliable. Most importantly there must be some space from where the steam must get disperse easily rather than enclosing it in a close box causing damage to wood. Bending this way does give you a couple of advantage that there is no need of glues and the material is not wasted. But there are also some drawbacks that the world might not take the exact shape which is expected, also depending on the quality of wood it might break on certain critical curves because of instability in shape.
Laminating Wood Bending
Another method used for wood bending is by laminating the wood. In this method wood is cut in several pieces and is then laminated with the help of glue or sticking substance that will hold the wood in its bent form and is then clamped for the glue to dry. When the glue is dry it will hold the wood in bent shape. However, there is quite a loss of material in this type of bending as a huge amount of material is wasted at the saw blade. The more adhesive the material is; the more effective and exact shape is adopted by wood also laminating material also helps to strengthen the delicate curves. So all in all it does provide a more effective and stronger bent shape than steam bending.
Wood Bending by Wood Kerfing
Last but not the least; another technique used for wood bending is kerf-cutting method. The word kerf means to make a cut in the wood. Now in this case making a cut does not mean to cut the wood into pieces that would certainly be inappropriate. It means to specifically make a cut taking in regard of the thickness of that wood. Now the amount of curviness depends either on the amount of saw cuts or to the crushing angle by which the saw cut is being made. Most importantly these saw cuts becomes the inner side of the surface and is filled with adhesive material so that the saw cuts are closed and get more strength. Due to which we can certainly see the cuts from its sides but not from its upper or lower surface.
Other than above those techniques of wood bending, there are another wood bending methods which are as follows:
Compression Bending for Solid Wood
Cold Method of Solid Wood Bending
Hot Method of Solid Wood Bending
Wood Bending with Micro Wave Heating
Hence, all these techniques reveal a whole new world which is capable of producing nicer, stronger and more beautiful wood appliances. It is just a matter of fact that either we still want to keep on looking for new innovations or not.
