(1) need to use sandpaper polishing or soft stick bamboo clappers. In the polishing round or spherical surfaces, using soft stick can be a very good working round face and spherical radian. The harder wood, like cherry wood, is more suitable for flat surface polishing. Trim the ends of the strips so that they conform to the appearance of the steel, so that the sharp angles of the slats (or bamboo bars) are prevented from touching the surface of the steel, resulting in deeper scratches.

(2) when changing the sand paper of different type, the polishing direction should be changed from 45 degrees to 90 degrees. Such a type of abrasive paper can be distinguished by the stripes left behind. The change is not the same type of sandpaper before, it is necessary to use 100% pure cotton dipped in the cleaning liquid alcohol, carefully scrubbing on polished appearance, because of a very small gravel in appearance will destroy all the next polishing operation. This process of cleaning is equally important when it is polished from sandpaper to diamond paste. Before polishing continues, all particles and oil are necessary to be thoroughly cleaned.

(3) in order to prevent scratches and burns, the appearance of the workpiece should be particularly careful when polishing with #1200 and #1500 sandpaper. Therefore, it is necessary to load a light load and choose two steps polishing method to polish the surface. Polishing with each type of abrasive paper should be done two times in two different directions, each turning about 45 degrees to 90 degrees each time between two directions.
