Chapter Seventy-Four: Great Craftsmen

"That's not good, if you like it, let the deer carpenter make another one, syringe or syringe, you kid is not allowed to have other thoughts. Pen %Fun %Pavilion www.biquge.info Look at this needle again, it is matched with this syringe, Uncle Fang has also tried it, it is just right. Fang Qiong took out a small silver cylinder from the wooden box.

The small silver cylinder was only the thickness of a chopstick, Fang Qiong lifted the lid at one end of the silver cylinder, poured out a small silk cloth bag from the inside, opened the small silk cloth bag, twisted out a silver shining needle, and held it up in front of Gong Nian Huai, "Nian Huai, look at this silver needle, it can just be loaded on the syringe, and it can be lived." ”

Gong Nian Huai's little heart beat happily, and the craftsmen of the Song Dynasty described it as ingenious, which was a little insufficient.

In the Han Dynasty's gold-threaded jade clothes, a gold wire was only a fraction of the diameter of a hair, and this was not counted, but it was necessary to drill holes in the gold wires thinner than a hair, and then string these gold wires together. In the era when there was no microscope, and there was no magnifying glass available, the ancient craftsmen only relied on a pair of naked eyes, how did they make it, and Gongyi Nianhuai was always very curious.

The needle in Fang Qiong's hand was not much thicker than the gold wire, and it was not too shocking that the craftsmen of the Song Dynasty could make it.

It's just that this needle, from the perspective of workmanship, is no less than the products produced by machinery in later generations, and it has an artistic atmosphere that mechanical products do not have.

Gong Nian Huai took the needle and looked closer.

"Nian Huai, there is a font number engraved on it." Fang Qiong squinted her eyes and stretched out her finger to point at the end of the pointer.

"Pan's silverware!" Gong Nian Huai finally saw it and read it softly, "Uncle Fang, is this a bit redundant?" It takes time and effort to make this needle, and then engraving the words on it, this effort is expensive, hehe,"

"You kid prides himself on being a descendant of the Gongyi clan, why don't you say some layman's words. This font size is reputation, is a guarantee, no real ability, who dares to engrave words on it? If it is smashed in the hand, the family will have to eat and sleep in the open air, and even the ancestors will not accept it when they die. Boy, don't underestimate these extra words. ”

Fang Qiong looked at Gong Nian Huai painfully, and almost poked his finger at Gong Nian Huai's head.

"Hehe, yes. Kid understood. Overseas travel has broadened my knowledge and knowledge, and it seems that I have lost a lot of things that are more important than what I have seen. ”

Gong Yi Nianhuai scratched his head and smiled wryly.

When Gong Yi Nianhuai picked up the needle of the iron pear wood again, he not only felt the weight of the iron pear wood, but also felt the perseverance and pursuit of the craftsman.

The starting point of each little idea of these craftsmen is from a small point of view, they do their best, light lamps and boil oil, nothing more than to occupy a favorable position in the peer competition, let their works sell at a good price, and make a safe life for their families.

Just like this small torsion spring, from creativity to production, how many people's youth have been consumed. More people who want to try it have become pioneers who have been photographed dead on the beach, and latecomers have stepped on their corpses, still moving forward, pushing technology forward with difficulty and unyielding.

It is not an exaggeration to say that they have led the development of science and technology in the entire era. When the craftsmen consciously make and use springs, the smelting industry needs to smelt steel suitable for making springs. In the process, new smelting processes are created that can even awaken chemistry in a hazy state.

Gong Nian Huai can proudly claim that he is more than an order of magnitude higher than these craftsmen, but Gong Lose Nian Huai's height is precisely standing on the shoulders of these craftsmen.

From the perspective of innovation, we should be ashamed of our losses. Because whether it is penicillin or artemisinin, it is plagiarized from future generations, and there is no credit for the slightest credit of the public loss of Nianhuai, let alone innovation.

This syringe made of iron pear wood has the entire cylinder hollowed out from a single piece of iron pear wood. That's it, after all, the cylinder is thicker, and it takes some effort.

What surprised Gong Nian Huai was how the small hole at the front end of the syringe was drilled. This is iron pear wood, the hardness is extremely high, and the small hole to be drilled is extremely thin, what tools and what techniques can be used to drill through the iron pear wood to drill such a thin hole?

A syringe is essentially a piston. The piston is inserted into the syringe. How the piston is in close contact with the inner wall of the syringe without air leakage is the key to the syringe.

Gong Nian Huai raised the syringe to the window by the light, and glanced at the side of the syringe *** smooth as a mirror, but he couldn't see the unevenness, even if he used the most critical eye, he couldn't pick out even the slightest flaw.

Gong Nian Huai was not only impressed.

Look at the pistons again. About a centimeter above the low end of the piston, a dimple is cut out, and a thin strip of Eucommia ulmoides is embedded in the hollow. If you don't look closely, the strip is flush with the piston and has no protrusions. If you look along the outer wall of the piston, there is a slight protrusion in the insertion of the rubber strip, which ensures that the piston and the inner wall of the syringe are tightly fitted. Due to the toughness and elasticity of the rubber strip, when the piston is pushed and pulled, it is neither tight nor leaky, and it is no different from the syringes of later generations.

If it weren't for the fact that this was made of iron pear wood, Gong Yi Nianhuai would really want to try the effect of this syringe now.

The only drawback is probably opacity. Scales can be marked, but useless. It seems that we have to find another way to determine the amount of injection. Or instead of syringes, use hanging bottles for infusion. However, the question of how much injection is still not solved.

What worries Gong Nianhuai even more is the material of this syringe. The syringe is to be charged, whether there are side effects of the pear wood itself, whether it will cause adverse consequences if it comes into contact with different liquids, etc., are all problems.

And Eucommia ulmoides strips, do they meet the hygienic standards? Will there be a reaction when in contact with the chemical solution? It's all unknown.

Gong Nian Huai didn't dare to test human life casually.

Infusion with a hanging bottle is much simpler. A small porcelain vase with a cork, plus a Eucommia hose and a needle is OK. If you are worried that the hose is unsafe, you can prepare more, use it several times or specify how long it must be replaced, which can effectively reduce the chance of medical accidents.

With this syringe, Gong Yi Nianhuai has some confidence in the time and space of the Song Dynasty. Or maybe some of his ideas can be put out and implemented more confidently.

"How?" Fang Qiong was dazzled.

Gong Yi Nianhuai held a syringe to push and pull and sing, and had a lot of fun. Look at the inner cylinder wall for a while, stuff the piston in and push and pull it a few times, look here, look there, more concerned than the security check.

Fang Qiong's patience with this child is still enough. Since he is a descendant of the Gongyi clan, he naturally has vision and insight that ordinary people do not have. Of course, what interests him will be different from ordinary people. What he was interested in was not something that an ordinary butler could understand. Or what he can understand as an ordinary housekeeper, he is not worthy of his condescending flattery.

It's just that Gong Yi Nianhuai looked at the box with such interest and tried the needle, he Fang Qiong was a little tired when he accompanied him, and he saw Fang Qiong's sleepiness welling up, two tears rippled, not forbearing, yawning I don't know how many baskets I had.

"Very good. Wonderful. Gong Nianhuai gently placed the syringe on the silk cloth, carefully rolled it up layer by layer, and put it back into the box like a newborn baby, closed the lid with a click, and let out a long breath.

"Oh, then let Lu Yiming make a few more." With the sound of this click, Fang Qiong's heart also returned to its original position, and she could talk happily again.

"The little nephew has no opinion on the workmanship of the syringe, but the little nephew is not very relieved about this material." Gong Yi Nianhuai rubbed the wooden box and groaned.

"Material? Nian Huai said, I want the laurel tree in the moon, and Uncle Fang will also help you find it. When Uncle Fang heard this, it had nothing to do with the craftsmanship of the deer carpenter, and half of his heart was relaxed. Materials, only if you can say it, my Qiong can find it for you.

Gong Yi Nianhuai smiled, "Uncle Fang, you don't need to be so exaggerated, the materials that the little nephew wants are not there, but they are too expensive, we can't afford to use them, and we don't need to waste them." ”

"What? It's too expensive! Hehe, "Fang Qiong was anxious when she heard it, and she was also humiliated, and she was told to her face that she couldn't afford it, I, grandma!"

Fang Qiong was about to pat her chest, maybe she felt that her momentum was insufficient, she rolled up her sleeves, and stalked her neck, the green tendons on her neck jumped straight up, three points stronger than the aggressive rooster, "Nian Huai, say it, you still don't believe it, there are still things that we can't afford in the Great Song Dynasty, you just have to say it." ”

Gong Nian Huai saw that Fang Qiong was really anxious, and went over to remove Fang Qiong's sleeve, "Uncle Fang, you, don't get excited." The little nephew knows which material is suitable, it is really too expensive, there is no need. There is another way to use, which is simple and inexpensive. ”

"It's expensive or not, Uncle Fang has the final say, you kid don't have to save Uncle Fang on this. Which material, how expensive is it, and where can I buy it? ”

"Glass!" The public loses Nian Huai can't bear it, and there is no need to endure it anymore. Zhu lips opened lightly and spit out two words.

"Hiss---, hiss--Yo, Nianhuai, you want Uncle Fang's life. Glass is something that can only be obtained by maritime merchants who go to the South Seas, and it is all fancy such as cups and bottles, where will there be the syringe you want. When Fang Qiong heard this, she sat down on the maza, and it was really difficult. There is probably a little embarrassment of blowing the cowhide on the spot.

"Uncle Fang, those things in Nanyang, my little nephew can't look down on them yet. Isn't time tight, and the little nephew wants to find some emergency ways to use it temporarily. Gong Nian Huai turned behind Fang Qiong, stroked the old man's back, and said comfortingly.

"What? Nian Huai, listen to your tone, you can't look at the glass in Nanyang, don't say that you can get out of the glass, Uncle Fang's heart can't stand it. Fang Qiong tilted her head and squinted at Gong Nian Huai behind her, one hand had already been pressed on her heart.

"Hehe, Uncle Fang, you really have to take care of your heart. The little nephew may be able to drum out the glass for you one day. ”
