The master jade craftsman thought for a moment: "If we make two at the same time, we are not sure of anything, but we have four workers, the bronze and the iron, together with the pyrotechnics, we should be able to complete one before dawn, and the rest will be much easier." ”

When Lin Xi heard this, he understood what the jade master meant, in the past, they were often reluctant to cooperate with different types of work due to the remuneration system, but now this situation must be changed:

"I understand, Song Aoxing, and everyone listen, we must overthrow these things that are not conducive to production, not conducive to promoting efficiency, and not conducive to people's spiritual emancipation.

Song Aoxing, you need to actively coordinate and cooperate with the Cheli project leader in the telescope project, which is also a top priority.

In the car, you need to properly discuss with the team members, with the best speed and efficiency, to make the first finished product, in this process, you either record by yourself, or ask Tang Hanlin to help you, be sure to record your personal contributions, truthfully one by one, in the future, you will be rewarded for meritorious deeds, do not be biased. ”

Song Aoxing said with the car: "Oh"

......

At this moment, Mi Sanmei and Song Qing were about to enter the door, while they were still fighting, Lin Xi coughed, and the two of them stopped a little, walked in in in a proper manner, and took Qingxu Zhenren and a few other people.

All the personnel entered the cabin and saluted in unison.

Lin Xi said: "Sit down, Wang Zhong (Qing Xuzi), you know the matter, right?" ”

Wang Zhongdao, a pure and honest person, said: "The two young generals have already mentioned to the poor Dao, the Venerable Master is in urgent need of lead? ”

Lin Xi said: "Yes, there is no lead, we need to find another way to make batteries, then we need silver, of course, if we have to do so, we can also use it." ”

Wang Zhong, a pure and pure man, said, "Since the Venerable Master thinks that it is necessary to use the lead, we will do our best to find a way. Jingshan (note: the Dharma name of Wang Zhong's disciple), you are the best at alchemy, you are familiar with these things. ”

Jingshan takes a steady step forward:

"Back to the Venerable Master and the Master Hui, in my view, the method of making utensils is very unique, so there are many uses of lead, which are mainly used for casting brass vessels;

In addition, the disciple was secretly passed on by the Qing Illusion Dan Master thirty years ago, saying that the great chaos is coming, and I have a lineage, some kung fu, and I can't break the inheritance, so I have endured the thunderbolt and the thunder technique, and the disciple has a lot of speculation, although the kung fu is not as good as the Qing Illusion Dan Master, but it is barely used.

However, after seeing the Venerable Master's primer fuse, I realized that those refining methods were too coarse and could not be compared.

In my box, there are about two catties of refined lead, and I can only use these materials for tonight's production.

If you want more, you may have to go to some city companies or special mines to procure.

However, if I find a vein of lead ore, I will refine it. ”

[Note: The activity of metal zinc is higher, the metal zinc is ground into powder in the oil, packaged, if exposed to the air, encountering high temperatures, and mixed with sulfur and other items, it may cause explosions, so now metal zinc powder is a vulnerable explosive, according to the "Regulations on the Safety Management of Hazardous Chemicals" by the public security department. 】

After speaking, the Jingshan Daoist looked at it again, retreated half a step, stood aside, and stood still.

Lin Xi said: "It's so good, let's do it with two catties first, at most make it thinner, and make at least two battery packs, that is, 72 pieces." ”

Lin Xi had to go over a drawing board again, and said while drawing:

"Come, let's continue to see, you have to make a tool to test whether there is a voltage or not.

Find a small plank, cut it into two inches wide and four inches long, and see what size is most comfortable for you in the future.

Use copper sheets to make an elastic board, fix one side to the front end of the board, and knock it to death with nails on both sides;

On the other side, also use copper sheets to make an elastic contact plate, which can be made into a semicircle, and it is also necessary to use a nail to knock it to the back end of the board.

Remember: the platen is four inches long, and the free end is about one to two minutes away from the elbow of the contact plate, about one to two minutes (note: one point is about 3 mm), do not touch.

The pressure plate exceeds the contact position, and it should be extended out by one to two inches, and you can master your own feel.

When using, press your fingers against the platen, and when the platen touches the elbow of the touchpad, they will be energized.

This is called the send button. ”

Lin Xi marked the drawing instructions of the bulletin button on the drawing board.

Then, Lin Xi said:

"You need to draw a lot of fine copper wire, divided into two kinds, one is a third of a part, and then wrap cotton silk on the outside, soak it in tung oil, and then dry it or dry it.

There is also a kind of only one-sixth to one-tenth, when you draw, control the temperature of the copper wire, pull it out here, and then you can brush it with tung oil, which can not only cool down, but also make the tung oil on the copper wire cover firmly. ”

At this time, the lacquer maker came up: "Dare to ask the Venerable Master, why is such a thin copper wire covered with tung oil instead of raw or cooked lacquer?" ”

Lin Xi felt very abrupt, but very happy: "May I ask what you do?" ”

The lacquer master hurriedly bent down and saluted: "Don't dare to ask, the old man is a lacquer master, the ancestors of the primitive Central Plains three generations ago, and then fled to Lingnan, married a local woman, and later mainly made lacquerware, so it is slightly familiar, the villain's surname is like Mu, and it is an allusion to the spring breeze." ”

Lin Xi said: "To be honest, I don't know a lot of things in the world now, and my understanding of the development of technology and technology is also very limited. I need you to let me know more and learn more from each other.

I have only seen tung oil and lacquer, lacquer, raw tung oil and cooked tung oil, but I have never collected, made or mixed it. So it's very superficial to understand.

Diao Rumu, you are very good, you just have to have such a spirit.

The slightly thicker copper wire I just talked about, wrapped with silk thread, cotton thread or twine, plus tung oil impregnation and drying, is to protect the copper wire with the shell of these tung oil and cotton silk, so that in use, it will not be electrocuted, enhance the strength, they will often move and touch, and even bear a certain weight and tension.

The finer copper wire mentioned later is only wrapped in tung oil, which is called enameled wire there, but I don't know much about paint, so I just want to use tung oil to do it, its characteristics are that the paint film should be firm and thorough, of course, it is good to be thinner. These enameled wires, after being made, will only be fixed in a container, and will basically not be invaded or rubbed by the outer ground.

Master Diao, what do you suggest? ”

Diao Rumu made another salute: "The Venerable Master doesn't care about our vulgarity, and he is so humble that it really makes the villain frightened, and he ......is grateful."

Lin Xi smiled and said: "Master Diao, now it is not above the court, but in the workshop, you just have to say it." ”

Diao Rumu said:

In this way, the villain is presumptuous.

There is a saying in "Zhuangzi • The World": "Lacquer can be used, so it is cut", which is why the lacquer comes from picking and cutting raw lacquer.

The lacquer liquid naturally secreted from the lacquer tree forms a black and shiny paint film when exposed to the sun.

"Book of Songs" cloud "set the square, made in the Chu Palace, in the Chu room, made in the Chu room, the hazelnut, chestnut, paulownia, Zizi, lacquer" of the tree, so the pre-Qin period has been widely planted, Chu land, Yizhou (note: today's Hubei, Sichuan and other places) is particularly so.

The benefits of lacquer are waterproof, insect-proof, sterilization, anti-corrosion, and the paint is resistant to acid, salt, moisture, and strong coverage, which can not only beautify, but also protect the utensils. The disadvantage is that it takes a long time to collect and mature, and it takes a lot of effort to dry the paint. And, expensive!

Later, it was found that tung oil, tung oil is easier to obtain than lacquer, the cost is much lower, the tung tree seeds are pressed, a pound of seeds can produce three taels to six taels of tung oil, and lacquer has to wait until the lacquer tree grows for at least eight years, and can only cut the tree to take lacquer.

However, the tung tree can bear fruit in two years, and it can enter the full fruit period in five to six years, and each tree can hang fruit five or six hundred catties per year. All the people who come and go often mix tung oil in the lacquer, and the oil is mixed with the lacquer.

Tung oil dries faster than lacquer, is lightweight, shiny, easy to adhere, has better heat resistance than lacquer, and has good permeability, so it can be made into oilcloth, but lacquer cannot. In addition, tung oil and lacquer have good insect repellent properties.

Raw lacquer is divided into raw and cooked, and tung oil is also divided into raw and cooked.

There are only two colors of lacquer, black and red, and the others are not good.

The color of tung oil is lighter, and the coverage depends on the pigment added inside.

If the Venerable Master needed a ritual vessel, then it had to be lacquered.

If the Venerable Master does not need to make ritual vessels, then tung oil can be used for both types of copper wires, and cooked tung oil must be used in order to dry quickly.

I am good at refining tung oil, but I need the cooperation of a copper master to draw copper wire and hot tung oil.

But I wonder how many of these copper wires the Venerable Master needed. ”

On the one hand, Lin Xi listened to the introduction of the lacquer master and was interesting and knowledgeable, so he paid special attention to and praised them for introducing it like this, which was conducive to their own literacy, and on the other hand, it also gave them full respect, which was beneficial to them or a happy to say something at home. When I heard how much I wanted, I said: "The thick copper wire, let's call it three milli cotton silk tung oil copper wire, referred to as three milli copper wire; The other is about one millimeter thick, which is called one millimeter copper wire. If you ask how much, then, three millimeters of wire should be made at least two or three zhang, and one millimeter wire should be made at least three or four zhang, and it should be used urgently. ”

At this time, the copper master spoke: "Venerable Master, the smallest one we usually make, that is, the thickness of three milli wires, and the thinner one has not been pulled. ”

Lin Xi said: "Go and try it, I really can't pull it out, three millimeters or two millimeters, so I'll make do with it first." ”

Lin Xigang wanted to say that they should go down and do it first, but suddenly thought of a specific question: "Master Diao, how do you dry and collect the tung oil on the copper wire?" ”

Master Diao was obviously stunned: "Master, the villain doesn't know what you mean?" ”

Lin Xi said: "The copper wire we make needs to be dried in tung oil outside, right?" ”

Diao Dajiang said: "Dry, yes, after we pull it out, we will use two big nails on the boat gang, one end is wrapped, the other side is wrapped with another nail, and then the yarn to be wrapped, then let people wrap it, and then brush tung oil, after brushing tung oil, find someone to use a small carbon stove, bake while walking, and so on." ”

Lin Xi asked, "How do you collect it?" ”

Diao Dajiang said: "Collect? This, but never thought that in the past, I have not used tung oil wrapped wire, if it is dry, you can use a wooden brace, and gradually wind the wire to close the line. Feasible?

No, the copper wire is fragile and should not be bent too much, so make a disc or octagonal reel, with a minimum inner diameter of eight inches to one foot, so that the wire is closed, and it is safe. ”

Lin Xi thought about it, and it was estimated that it would be like this for the time being, and the rest was actually more difficult for copper wire drawing. Then he asked the copper master: "Copper master, copper rod drawing, do you have any difficulties in doing it?" ”

The copper master is really unambiguous:

"What the Venerable Master said is that drawing copper wire is also a mystery that has not been passed down from house to family.

Generally, the wire is easy to pull, and that thing is stronger.

Copper wire itself is much less strong than iron.

Wire drawing needs to heat the iron rod or copper rod first to soften, and then clamp a head, and then put it in the middle of a column and a pressure column made of steel, while it is hot, draw, if it is a short line, the force may be more even, if it is long, the line will sink and bend, the force is very difficult to grasp, and the size gap between the column and the pressure column, I can't see it, I want another person to grasp it by hand, and two masters need to do it at the same time.

And the column is thin, and there is a problem, that is, the last line, which is a flat line.

Therefore, there is also a small hole drilled with a steel plate, in that case, the copper or iron should be burned softer, and one end of the copper rod should be knocked fine first, so that the hole can be pierced, and then drawn while it is hot.

Nowadays, it is necessary to make only one millimeter of wire, only a round wire, a milli hole, open on the steel plate, itself needs no more than one millimeter of drill bits, no more than one millimeter of drill bits, how can you drill half a point to a minute thick steel plate? ”

Lin Xi asked: "If it is less than a millimeter, then the line is very soft, why do you have to make holes in the steel plate?" ”

The coppersmith asked, "It's soft?" Could it be that the Venerable Master meant that the method of pressing the column and the column was used, but in this way only a thin slit was filed on the column or the column? ”

Lin Xi said: "That's the truth,"

The master brass suddenly realized: "It's not the Venerable Master's reminder, we are still entangled." It's much better. ”

Lin Xi said: "Thin wire, don't pursue it in place at one time, you should pull it out a few more times, use a red-hot copper rod and copper wire every time, wear it, don't cool it quickly, you should degrade and keep it soft, you go down and do it first." ”
