Bending wood is a complex thing. Although trees have inherent curves, most wood does not naturally want to bend. However, there are some techniques that can be used to bend it, such as slit cutting and steam. [jar make] there is a clever technique that can use CNC drill bit to make better incision cutting.
Usually, a bench saw or miter saw is used to cut a cut on the groove. Many laser cutting boxes use notches instead to bend the workpiece. The disadvantage is that the incision is straight and the thickness of the whole incision is the same. This means that when the wood is bent into its shape, if you want the wood to look continuous, you need to fill a large gap. Hackers invaded by using a 6.2-degree taper router (not a network type). This means that the incision it forms is angled. By placing an appropriate number of cuts and evenly separating them, a perfect circular curve can be obtained. In order to make the interval more uniform, he quickly made a fixture so that the cutting can be repeated. Once all the cuts are cut, it’s time to bend, [jar make] uses some hot water and fabric softener to help bend. His bookshelves are beautifully arranged.
He made an important statement that this CNC bit did not use this use case in my design, and it has a high probability of breaking or breaking. If you try to replicate this technology, taking precautions to ensure safety is the key. Maybe you can dig some frame wood and bend it into beautiful furniture.
