100 (hereinafter referred to as sandpaper) shall be molded in place at one time, and 300, 500, 800, 1000, 1500, 2000, 2500 and 3000 shall be polished step by step (a sign can be added in the middle, and the more grades, the more labor will be saved, and each level will be polished. The principle of grinding is that the last grade sandpaper removes the grinding traces of the previous grade sandpaper. Polishing according to the procedure is the fastest and most labor-saving method. If you don't polish it according to the procedure, for example, from 600 to 1500, you will have to hone your temper. I don't think I can get rid of 600 wear marks in a day. Ha ha laugh
Polishing support table is divided into rigid support and flexible support, and the polishing plane needs a plane rigid support with good rigidity, preferably steel plate or thick glass. Wooden countertops don't grind easily. Force evenly, control the four corners, or front, back, left and right, and don't be biased. Push hard before the rough grinding stage and push lightly at the end. Use new sandpaper first and old sandpaper last.
The next step is to remove the grinding marks of the previous step. First, wipe off the dust with a cloth and observe the grinding marks in the light. Every label should be polished in place and not sloppy. After 600 years, the golden thread began to appear slowly. About 800 is the key, which is exactly the hole size of Jin Sinan, so we should spend as much time grinding the hole as possible. Ok, Jin Sinan, it will be even more dazzling after 1500. I have tried many times, and 3000 is necessary. /kloc-above 0/000 must be patient. Polishing to above 1000, it is best to wear gloves to avoid the influence of sweat pollution on observation.
It is best to grind the sample by hand, and the speed needs to be greatly reduced by electric grinding. The high temperature of the electric mill will burn the wood, and the original fragrance of Jin Sinan will not be smelled if the smell goes into the wood, at least it will be seriously affected. High temperature will also accelerate the volatilization of Jin Sinan aromatic oil.
The process of polishing is also a process in which players are familiar with woody plants. Try to collect oily wood powder, which can be used for incense and restoration in the future. More knowledge about Nanmu can be learned through Sister Mu Gong Hao.
Grinding method supplement:
Dry grinding or wet grinding? Jin Sinan can only dry grind, but can't see water. Polished surfaces are prone to pilling and cracking when exposed to water.
Because the real Jin Sinan is oily and wastes a lot of sandpaper, it can be recovered by cleaning and polishing sandpaper, so that sandpaper can be used repeatedly. When reaching high grade, flexible support can be used and a piece of cloth can be put under the sandpaper, which is economical and can avoid the sticky particles of high grade sandpaper from scratching the wood.
It is recommended to seal the wax and block the eye holes to keep the fragrance longer. Natural beeswax itself has a slightly sweet fragrance, which is consistent with that of Jin Sinan. You can do without beeswax and paraffin. Methods: Dry-coat the surface carefully and evenly, fold the high-grade facial tissue properly and rub it until it is bright. Burning wax is not recommended, because wax will discolor wood. There are some different ways to play about whether to seal wax. My feeling is that Jin Sinan belongs to cork, which is easy to get dirty. In contrast, waxing is better.
Jin Sinan belongs to cork, so it is forbidden to scrape nails, touch hard, fall to the ground, get wet, etc. Don't put a bag with keys, etc.
Use pure cotton cloth or a plate with gloves for the first two months, and then get used to it gradually until it is wrapped. The patina is a layer of transparent perlite, which is very beautiful.
