Second, how to sand and polish wood

1, usually draw a creative draft, and then enlarged to the wood with an ink line outline;

2, the rough blank is the basis of the entire work, it is a concise geometric form to summarize all the ideas of the modeling, the requirements of the level, There is momentum, proportionality and coordination, the center of gravity is stable and strong sense of integrity, the initial formation of the work of the outer and inner contours; chiseling rough: can be from bottom to bottom, from front to back, from the surface to the inside, from shallow to deep, layer by layer to advance. Chisel rough also need to pay attention to leave room for maneuver, as cutting clothes, to appropriate relaxation. Folk jargon says: "stay fat can change the small, but worry about the barren hard to regain fat, the distance should be small not big, remember that carving is subtractive." Chiseling fine blanks: first from the overall perspective, adjust the ratio and various layouts, and then the specific form of the gradual implementation and shaping, to leave room for the repair of light. At this stage, the volume and lines of the work have become clear. Article has tended to be clear, so the knife is required to be rounded and smooth, to have full expressive power;

3, repair light: the use of fine carving and thin knife method to repair the fine blanks in the knife marks chisel dirt, so that the work of the surface is detailed and perfect. Requirements for clear and fine knife, or smooth, or board straight, or rough, and strive to accurately express the intention of the work;

4, sanding: according to the needs of the work, the wood carving with different thicknesses of carpentry sandpaper rubbing. Requirements for the first coarse sandpaper, then fine sandpaper. To follow the direction of the wood fiber sanding, until the desired effect;

5, coloring and varnishing: with a hard brush, a small hard brush, a palette tank. The pigments for coloring generally refer to water-soluble ones, such as gouache, watercolor or shoe polish. They are characterized by small coverage and strong penetration. Acrylic paints for oil painting should not be used.

The method of wood carving coloring is mainly to master the wood and pattern in the pigment coverage is still visible, some wood grain through the coloring more clear. So in the deployment of color should not be too thick, the ratio of pigment to water is 30:1, to be appropriately thin, transparent. So that even if more than a few times, the wood will not be covered, if the color is properly blended, coloring the brush brush should not contain too much water, do not rush, otherwise some deep concave place to accumulate color easy to produce uneven results.

Coloring is not only to make up for certain wood deficiencies or defects, but also play a role in enriching the beauty of the texture of the material and the works of formal beauty. Therefore, in the work of coloring should be discretionary, the requirements of the work as much as possible to reflect the form of the content of the demand, and in line with the natural wood of all kinds of beauty.

Wooden sculpture coloring do not immediately wipe the light. Must wait for dry (about 12 hours later), with a clean cloth to wipe vigorously until a uniform luster, to achieve a smooth feel. Some works can be rubbed depending on the circumstances of some leakage, so that the base color of the wood is slightly exposed, the formation of a rich sense of color, but also strengthens the sense of hierarchy of the work.

The above gives you an example of woodworking grinding and polishing process of common tool selection, as well as specific steps and implementation methods, it can be learned, because the ordinary surface of the wood is rough, in order to be able to process them into a smooth surface and color with a sense of glossy furniture panels or other accessories, then it is necessary to grind and polish processing, and choose the right tool! Can improve our work efficiency, to ensure that the later satisfactory results, such as the above examples of several grinding and polishing power tools is a good suggestion.
