Making Chairs Curved Legs

To follow and size ergonomic design, rear-seat leg often be set up such that the curve looks better and fits with the desired angle.The curved legs forming process through several stages of processing. For those of you who are involved in the production would have to know the process.
The process starts from the selection of wide planks that have been dried. Board thickness should be adjusted to the thickness of the straight leg plus the spelling of machines and abrasive planers. Minimum width of the board is the perpendicular distance from the tip of the foot arch to arch its biggest field. Wider board would be better for the cleavage results and saving wood.
S2SFor results and a better process, boards should be planed smooth on two sides, namely the width of the finished thickness, exceeded 0.5 mm for the sandpaper. This harvest will help the accuracy of the image forms the arch on the board.

Describe your desired curvature on the surface of the board using a curved scale 1:1. Mal used to draw on the board can be cardboard, plywood or plastic. Whatever the material used should have a stable nature and not easily broken.Tricks will draw useful in this process to save material by maximizing the entire surface of the board in order to produce the required curved shape. But the problem will sometimes occur depending on the type of wood you use. Wood that has many congenital defects (knots, sapwood, and other bluestain) will give little trouble and excess waste.
The next process is the cleavage of using band saw. Navigate blade 'OUTSIDE' excess lines so that there are still wide for waste processing. Note also that at the time did not cut sawing curved lines the other foot.

After each one foot visible arch shape, smoothing the thick side can be done with the engine side Frais, Copy Shapper, Multi spindles and thick sanding machine. Refinement can be done one at a time or all at once depending on the thickness of 4-10 stems. For best results we recommend it as well but this process requires a sophisticated machine that is able to bind more than one workpiece and capable of smoothing the excess thickness.When using this machine can also be done at an angle pingul process wood. Simply replace the blade types only.
Things to consider when making curved workpiece:1. Wood fiber direction: Think on which part of the component is mounted so that the direction of the fiber is aesthetically and construction will be good.2. Minimum distance between the lines for each workpiece is 5mm for spelling sawing and grinding.3. Use good stationery and sharp so it is not easily removed by hand or other object in the production room.4. Decay, avoid and reduce waste as much as possible to make a good cut line.5. Mall store in a safe place of collision.
