The specific method of erhu skinning:
1. Find the right size of unprocessed wood and select carefully.
2. After machine cutting, the appearance is not smooth and round enough and needs to be planed manually.
3. The headstock is pasted on the piano rod with strong glue and carefully smoothed and polished. The bonded joint looks perfect.
4. Select the best adult python back skin, soak it and stretch it to maximize its elasticity. Apply special glue to the piano tube and cover it with the python skin.
5. Use special tools to fix, tighten and iron, and attach a gasket made of celluloid to prevent the python skin from being damaged due to long-term friction of the bow. Remove the gasket after it is completely bonded. The excess part is smoothed off to be consistent with the edge of the inner piano skin.
6. When all the main parts of the erhu are completed, they will be rubbed repeatedly with coarse to fine sandpaper until the wooden surface is completely smooth. The handmade erhu is waxed with natural materials to eliminate paint and allow the wood to spread. The most natural and pure luster.
7. Carry out final polishing on a cloth wheel coated with beeswax and other mixed products. After polishing, add a carefully carved piano window, and a beautiful erhu can be assembled. .
