Bow piece material of laminated split bow

The laminated opening sheet is made of hard maple wedge, hard maple thin sheet or bamboo sheet, glass slide and polyester adhesive, and pressed into glass wood glass or glass wood bamboo glass by laminating method.

The traditional bow in China is a composite bow made of various materials. Its manufacturing process is complex, and the materials used are varied. The workmanship and materials should be suitable according to the season and climate.

(1) Bamboo: Bamboo used to make bows is mostly produced in Jiangxi Province, where bamboo is relatively strong, sturdy and durable. Usually, the quality of bamboo is evaluated by beating it to hear whether its sound is clear or not. It is best to use bamboo that has been cut and dried in the shade for one year. Bamboo with uneven thickness at the upper and lower ends or wormholes in the middle can't be used to make bows. Consider the loss when buying bamboo.

(2) Horn: A bow should use two horns, and buffalo horns with a length of more than 60 cm should be selected. At present, the purchase price in Beijing is about one in 30 yuan, and most of the horns come from Hubei. Because Yang Fuxi often entrusts people to buy horns, it is not easy to know when to cut them and whether they are all in pairs, so he can only choose pairs with roughly the same length.

(3) Beef tendon: Beef tendon is a very important elastic material for making bows, which is taken from the tendon ① on the back of cattle near the spine of cattle. Bought beef tendon, air-dried on the edge of the room, air-dried to 890%, wrapped in coarse wet cloth. The next job is to mash the beef tendon, which is convenient if you live in the countryside and can be ground on a roller. But there is no grinding in Beijing, so you can only hit it with a wooden hammer. Not too hard, but slowly. Crush it because it is too powerful. Crush it slowly to crush it. After smashing, you can see that the tendons have been split into strips. Then tear it bit by bit, to the required thickness, and finally become a trace. The process of tearing tendons is a slow job, which used to be done by women. People in the Archery often say, "A good man can't tear four tendons in one day." Tie the torn tendons and soak them in water in advance for later use. The longer the soaking time, the better. In the past, there were soaked tendons in front of the shops in the Archery. When it is used, it needs to be washed with clear water, and the effect is very good. The paved bow ② is also very smooth. If the tendon is not soaked for a long time, the master will say that the tendon is "dirty, hard and moist", and the arch surface made of it may have cracks, which they often call "water crack".
