1. First use a compass cutter to score the lid plate, then smooth the edge by hand or with leather, fur cloth, or hemp. 2. Flip the lid plate over and polish it, then use a wire rib tool to finish it. The hemp wire rib should be ground on a wooden turntable, which makes it easier to observe the rib tool. When making any tool, you can only gauge by eye (meaning you must first check whether the wire rib fits properly) and cannot test it directly. The posture for using the wire rib tool must be correct, otherwise it will affect the result. The wire rib should be angled slightly outward. **Scraping ribs**: Both the body cylinder and lid top must be scraped with ribs. The purpose of using compound ribs is to shape the body cylinder and lid top, achieving smoothness and refinement. ## Uses of the Small Bamboo Paddle - Large end — for making spouts and pushing the base - Small end — for pushing knobs The two corners of the small end are different, and when needed can substitute for clay application and covering ribs. The back of the paddle can serve as a cutting rib. The edge of the paddle is uniform from end to end, so this paddle can be used to compress reinforcing ridges. When making female molds, it can create false bottoms. It can also be used to smooth spout surfaces and spout tips. --- *[Note: The final line appears to contain corrupted or unclear characters in the original Chinese text and could not be reliably translated.]*
