Zheng Anmin didn't finish speaking, Zhu Pingjin already understood that he was going to invite himself to be the manager of the Firearms Bureau and take the blame for Zhu Pingjin.

Zheng Anmin is right, this firearms bureau is inherently a place to cause trouble. No matter how secretive the research and development of new firearms is, sooner or later it will be revealed to the world after equipping the troops. If there is no heavyweight official in charge, the court and local officials will inevitably pounce on it and take a bite.

Although the Changshi Division was originally an errand for the vassal king, Zheng Anmin, a civil official of the fifth grade, was equivalent to the rank of a scholar in the current dynasty, and took the initiative to go to a place of right and wrong like the Firearms Bureau, which still shows his outstanding responsibility.

A faint sense of apology poured out of Zhu Pingjian's heart. However, this regret seeped into the heart and spleen in an instant, and dissipated without a trace.

"This position of the steward of the Firearms Bureau, this son was renamed the chief steward. Since Lord Zheng is so well aware of the righteousness, then he has wronged Lord Zheng to take the same position! Mr. Wang, would you like to help Master Zheng? ”

Zheng Anmin took the initiative to shelter himself from the wind and rain, and Wang Kunshan couldn't wait. Both of them said yes, and the matter was settled. The two immediately began to select their subordinates. There are a lot of things about professionalism, personnel, materials, funds, transportation, security, security, and the placement of craftsmen's wives and children. A non-mainstream official of the Gongzheng Institute is named Li Li, who was highly recommended by Zheng Anmin as the general office of the Firearms Bureau. Zhu Pingjin saw that this person was young, but he didn't know what he was capable of.

After the meeting was dismissed, Zhu Pingjin did not leave first. He quietly instructed Li Sixian to let Wang Kunshan, Li Li, and several major craftsmen come to the Jinde Hall tomorrow afternoon to listen to him expound his views on the research and development of firearms. Zhu Pingjin left his seat by himself, grabbed Zheng Anmin and said: "If Lord Zheng is willing to appreciate the light, how about this prince to drink wine at night?" ”

Zheng Anmin was taken aback. He knew that the prince rarely drank alcohol in the palace, and this invitation, there must be a big matter to discuss. He remained silent, but said with a smile: "In this way, the lower official will talk to the prince for a few glasses of wine, and during the banquet, he just asked the prince to solve a question or two for the lower official." ”

"Why?"

"In the instructions of the prince of Fangcai, there are two words 'cadres and innovation', and the lower officials think about it seriously, which must have a deep meaning. The lower official is foolish, and wants to ask the prince to explain to the lower official. ”

Why do you want to show off in front of the non-commissioned officer? Zhu Pingjin yelled at himself in his heart. Don't you know that only three or four hundred jinshi can be produced in the whole of China in three years? With an average of more than 100 a year, in terms of rarity alone, Jinshi far exceeds the doctors and postdocs in his previous life.

Maybe the majors of the jinshi are not right, but their IQ is not to be bullied!

As a member of the D committee in his previous life, Zhu Pingjian, who was deeply poisoned by Marxist-Leninist thought, firmly believed in a basic truth, that is, the productive forces determine the relations of production. In order to promote the improvement of the production efficiency of the whole society, it is necessary to have advanced tools.

When everyone is still digging the earth with a hoe, fantasizing about running into capitalism is pure foolish dreams. Without the advent of the Jenny spinning machine, an efficient spinning tool, the British textile industry could not have developed an overwhelming advantage over the European textile industry. Without the huge profits of trade, it is impossible for the sheep of Great Britain to eat people. So, without the Jenny loom, there would be no sheep eating man; Without Watt and his improved high-efficiency steam engine, there would be no so-called industrial revolution.

The so-called "handmade" things in his previous life were actually mostly not handmade. They are nothing more than adding manual elements to an intermediate or final link in the production of the product. Is hand-ground bean curd made by hand? Definitely! The beans are genetically modified, and the beans are machine-grown and machine-harvested. What we can see is nothing more than one of the simplest and most eye-catching display links in the process of making bean curd - swinging the grinding disc round and round. The hand-ground beans at the entrance of the restaurant are often performative. What we really eat in the bowl is still ordered with soybean flour beaten from the kitchen machine. Thinking that the primitive is beautiful, thinking that handicraft is pure, thinking that the original ecology is staying in 5,000 years ago, these people should listen to what the real craftsman often says:

Three points of craftsmanship, seven points of tools.

Of course, Zhu Pingjin, who is under huge pressure to survive, will not think about how to let Daming enter the great blueprint of capitalism for the time being. What he urgently needs now is not to automatically defeat Zhang Xianzhong with the powerful productive forces bursting out of capitalism; Nor will they use parliamentary democracy to automatically eliminate the barbaric and backward Huang Taiji outside the Guanwai.

What he urgently needs now is a machine tool that can drill barrels.

That's right, it's a primitive toy machine!

Zhu Pingjin had a long talk with Zheng Anmin, Zheng Changshi, and Bingzhu last night, and drank a little wine. This morning he had to sleep lazily, until the third day of the day, his fierce wife lifted the quilt on the bed.

Zhu Pingjin ate breakfast and lunch together, and as soon as he finished eating, Li Sixian came in to report that Wang Kunshan, Li Li and a few craftsmen had arrived. He changed his clothes, took a few paper sleeves from a book, and then went with his wife to a new place of work, the Jinde Hall.

In addition to Wang Kunshan and Li Li, there were three craftsmen who were invited. In addition to the Feng brothers, there is also Shen Gui, the carpenter head of the Gongzheng Institute. Shen Gui is not like those two blacksmiths, he is lean and slender, and his eyes are bright. He was the carpenter's chief, and he used to build this and that in the king's house. Under the eaves, under the roof, on the beams, and under the table, his elusive figure was left everywhere, so Zhu Pingjin was no stranger to him. When they were done, the wife also went back to Wanfu very sensibly and returned to her office. Zhu Pingjin politely let a few people sit, and then in his wife's meaningful eyes, he smiled and sat on the dragon chair on the platform in the middle.

"This is a schematic diagram of a lathe used to drill a pipe." Zhu Pingjin handed over the paper in his hand to Wang Kunshan and several others to circulate, "Such a militaristic weapon. Don't make a big announcement, remember! ”

Looking at the simple diagram in his hand, Shen Gui suddenly said, "The villain has done something similar." ”

"You've done that?" Zhu Pingjin was very surprised. Could it be that this Shen Gui in front of him is also a traverser?

"Yushizi, exactly! What the villain made is not called a lathe, but a tuo bed, which is used to make jade. More than ten years ago, the villain followed the master to make a set of top beds for the jewelry of Gongzheng. Later, Qi Baozhai in the city also came to decide, and the villain made another set. There are many kinds of this set of tuo beds, including the tuo, the chisel, the hook, the rolling, the nail, the bowl, the bore, the bending, the grinding and so on. The style sounds a lot, but except for the grinding top, all kinds of other tops are similar.

A large table, this is called a bed. Under the bed there are two pedals, and the ends of the pedals are connected to a rope, which rises up from the square hole in the middle of the table, and circles twice around a wooden shaft, which is called a 'water shaft'. One end of the water shaft is cut thin and wrapped in an iron sleeve, and an iron rod is attached to the iron sleeve, which can be inserted into the round hole where the iron sheet is erected on the side of the table. The jade craftsman stepped on the pedal with both feet, stepped up and down, and the rope drove the water shaft to rotate back and forth. The tuo, the chisel, the hook, etc., are fixed at the other end of the water axis, and when the wooden shaft turns, the iron tuo also turns. By dipping it in sand and water, it is possible to cut or polish jade (Note 1). ”

Shen Gui gestured while talking, for fear that the prince would not understand. After finishing speaking, Zhu Pingjin immediately asked him: "The water axis of this top bed, one end is fixed and rotated, how to position the other end?" ”

"Positioning?" Shen Gui was stunned for a moment, but quickly reacted.

"The other end of the water shaft is not fixed. A rope was hung from the beam of the jade craftsman's house, and a large weighing rod was tied. A water shaft hangs from one end of the weighing pan; Is there one end of the scale, or the scale is hanging. The villain said that this weighing rod is an analogy, but it is actually a long wooden stick. The reason for this is that the water shaft is upturned at one end with a scale. The water shaft is upturned, and the rope on the pedal is always tightened. It's not okay if the rope isn't tight, or ......"

Zhu Pingjin answered: "Otherwise, the rope will slip." The bottom two feet stepped hard, and the upper water shaft did not move. ”

"Exactly!" Shen Guixiang found his bosom friend and slapped his leg excitedly, "The villain later felt that the tuo bed made by the master was inconvenient to move, so he changed it on his own initiative. ”

"How to change it, come quickly!"

"Yes! The villain felt that the rope was easy to slip when pulled around the water axis, so he used cowhide to cut leather strips instead of the rope, and the effect was not bad. The most changed is under this bed. The villain installed an iron disc under the bed to make a flywheel, and the two small pedals became one big pedal. There is a connecting rod in the upper right corner of the pedal with a rotating shaft protruding from the edge of the iron plate. When the person presses the pedal up and down, the connecting rod drives the hinge and makes the flywheel rotate. As soon as the flywheel turned, so did the iron tuo. Is this the benefit of changing......"

"The iron top only rotates in one direction, not back and forth. The two ends are fixed, and the iron tuo will not jump up and down, and the jade pieces can be finely polished. In addition, the weighing rod and weight on the top of the head are also saved, and the machine can be moved wherever it wants. Zhu Pingjin said, and an old object with collectible value appeared in his head: a foot-operated sewing machine.

"Yes, yes!" Shen Gui was so excited that he spoke incoherently, "Shizi is really a natural craftsman!" ”

This Shen Gui is so ignorant, Wang Kunshan suddenly sank his face. "Born craftsman", is this a compliment or a curse?

The face of the leader sitting at the top changed, but Shen Gui, who was excited, didn't notice it, and said to himself: "But the villain has changed, and I always feel that there is still a problem." ”

"Bearings?"

"Bearings?" Shen Gui was stunned again.

"It's how the other end of the water shaft can take root on the bed! The villain also nailed an iron sheet on the other side of the top bed, drilled a large round hole, inserted the entire water shaft into it, and hung the iron top outside. ”

When Shen Gui said this, he suddenly understood the meaning of the so-called "bearing" of the prince, and hurriedly said: "Yes, what the prince said is right!" It's just that the bearing is not easy to do! As soon as the leather strip is taut and rotated, the water shaft rubs against the bearing. After a long time, a deep groove grinded out where the two sides met, and it was about to break. The villain went to repair it a few years ago, added an iron hoop (GU) to the worn area of the water shaft, and smeared lard lubrication on the iron hoop. But recently, I heard people say that this iron hoop is also not wear-resistant. The hoop was thinned, and the water shaft began to shake back and forth when it turned......"

"Iron piece to iron hoop is iron to iron, hard to hard, it is the result of losing both. This bearing should be hard at one end and soft at the other. The one that is easy to replace is a soft one, and it will be replaced when it is grinded. Bronze is more wear-resistant than steel, so the hard end is made of bronze, and the soft end is made of steel. Lard to do lubrication, there are also problems. As soon as the weather is hot and the water shaft turns, the lard melts and cannot be lubricated. If you can't find other lubricants with a high melting point, add graphite, talc or lead powder to the lard. These are solid lubricants that are not afraid of heat. ”

When Shen Gui heard this, he suddenly realized, and at the same time he was annoyed, why didn't he figure out this hard truth?

It must be that I am not good at learning! Or is the master not good at learning? Or did the master keep a hand for himself before his death?

Thinking of the master who was like a father, Shen Gui shook his head vigorously and shook out this disrespectful thought.

Note 1: For the schematic diagram of the top bed, Xiangmu suggested that all book friends should Baidu by themselves, so as not to be spoiled by the words in the text.
