Ma San has been by Qin Kai's side for the past few days, and Qin Kai also understands the role of this guy, this guy is just an on-site observer, he is busy to death now, and he doesn't bother to pay attention to this matter.

That drawing is actually imperfect to a large extent, after all, it is a drawing made according to holograms, and each part on the drawing is just a thumbnail, so he has been desperately drawing part drawings according to the holographic images in the light brain next to the shed for the past few days.

Xu Guofang, a small official in the machine tool workshop, was taking his polishing master Lao Liu to make the standard steel shaft that Qin Kai needed, but he was also surprised to see other mechanics keep receiving drawings of various parts from Lord Qin, the reason was naturally because the speed was too perverted, and the technicians saw Qin Kai burying his head in a simple workshop next to him and kept drawing, and then the two disciples sent out drawings one by one.

And the drawings drawn by this Lord Qin are obviously different from what he has seen before, but they are very specific in terms of size, process, and requirements, so what the mechanic needs to do is to consider how to produce the parts with this requirement according to the drawings, fortunately, the variety of machine tools purchased in Mawei Shipyard has been very perfect, plus more than ten years of technical accumulation, quite a few disciples of technicians, and the production of parts is also carried out in an orderly manner.

This period of time is the most diligent day for the governor Yamen Sun Master to run the ship master school, almost every two days he has to come to the school to take a turn, at the beginning, but also to inquire about Qin Kai to understand the progress, but later, the news passed by Tong Guò Ma San and those little officials has made him very relieved, everyone is surprised by Qin Kai's crazy drawing speed.

And Qin Kai has temporarily entered the stage of recuperation after frantically drawing parts drawings for more than ten days, because the drawings that should be produced have been completed, and the rest is Xu Guofang's business, making parts is a technician's job.

He now definitely belongs to the role of a free man in the school, and the status of the governor's envoy gives him a very large amount of autonomy, so soon, his two disciples Huang Xing and Sun Xiang found that their teacher soon became unprofessional, and after purchasing some inexplicable materials from the foreign company on the dock, Huang Xing and Sun Xiang were arranged by Qin Kai to start chemical practice.

Qin Kai abused his power a little, asked the mechanic to polish a few molds with iron sheets, and after two days of tinkering in a shed, after losing more than half of the raw materials, Qin Kai proudly made the finished product he wanted, a few pieces of soap pressed by molds, which was the most basic sulfur soap he made.

He asked the two disciples to continue to record the details of the parts processing on the spot, and returned to Fuzhou City with soap by himself, because of his excellent watch, Master Sun agreed to advance his salary, and first went to redeem his high-tech watch, and then he hurriedly came to He Xing, "no money, nothing can not" The famous saying of later generations made him always remember his current situation.

He Xing has obviously been very busy recently, looking tired, he hasn't seen Qin Kai for a few days, and as soon as they met, he asked: "Brother Qin, what have you been busy with lately, why haven't I seen you for a long time." After that, he went inside and took out a document of registration and a certificate of guarantee from He Xing.

Qin Kai looked at these documents, this was something that had worried him all along, and now he had finally become a Qing Dynasty man completely, after carefully folding the documents, he took out those few pieces of soap and molds, and said with a smile: "Brother He, can you see if this thing can make money?" ”

This strange-looking thing immediately attracted He Xing's attention, he picked it up and sniffed it, and touched it a few more times, "Brother Qin, is this Western soap?" I've seen foreigners use it in Guangzhou, but it doesn't seem to be the same!"

Qin Kai laughed, this He Xing can be regarded as well-informed, but the formula of his own soap will not appear in China until a few decades later in real history, and now even if soap has been used in Europe for more than 100 years, there is still no development in the formula.

"Brother He, this is soap, which is naturally different from Western soap, and in terms of process and cost, it is far lower than Western soap, I don't know if you are interested in operating it?"

For this new type of product, He Xing naturally understood the huge profits contained in it, and asked with wide eyes: "Brother Qin, did you figure this out?" How much does this bar of soap cost? ”

"This recipe is unique, but this production also requires some skills, I have recorded them one by one, as for the cost, it is very cheap, and a piece of soap is about 20 yuan!" ,

He Xing now understood that he was lucky, and he was secretly glad in his heart for the wisdom of befriending Qin Kai at the beginning, this cost 20 Wen, and it is definitely not a problem to sell dozens of Wen, with a little packaging, the price can go up a little,

He said to Qin Kai very sincerely, "Brother Qin, this is a big deal, if the market is opened, I estimate that within a few years, there will be at least a few times the huge profit, I want to go back and discuss with my father, as for this profit, what my brother can guarantee, at least leave you forty percent of the profit." ”

Qin Kai nodded, "Brother He, this is all up to you!" Then I'll take my leave, if you want to find me, just come to the Mawei Ship Master School. ”

Time flies, a few days later, He Xing came to the news, the He family has deployed manpower, devote themselves to the new business, of course, in order to conceal and secure the operation, according to Qin Kai's construction, the goods are not sold locally in Fujian, but through Guò Mawei Port, first in Guangzhou, Shanghai and other ports of sale.

In the machine tool workshop of Mawei shipyard, the processing of parts is in full swing, as the director of this workshop, Xu Guofang is the first batch of craftsman apprentices recruited by Captain Mawei, at the beginning of the establishment of Mawei factory, he followed a few British people to learn the operation of machine tools, more than ten years of personal efforts, to get the current position.

Today is the final stage of polishing the iron shaft, an iron rod sent by the steel mill under his skillful operation, constantly grinding by hand grinder, the grinding wheel and the steel surface of the fierce friction, making a harsh noise.

This is already the fifth iron shaft polished, the first four iron shafts have failed to meet the requirements of Qin Kai's design drawing, he and Lao Liu have discussed a few times in private, and there is no better plan, Qin Kai is naturally very concerned about the problem of this iron shaft, and also joined in to discuss the plan, today this is the product that is polished according to the new plan.

He naturally admired this newcomer Lord Qin, not only was he capable, but he was also polite to the craftsmen under him, and he worked overtime every night to invite everyone to have supper, so everyone was full of energy. Finally, before nightfall, the final polishing action of this iron shaft was completed, this time Xu Guofang felt very good, he removed the iron shaft from the machine tool, and then took out a steel ruler, and Lao Liu measured the outer diameter of the steel shaft by millimeter with Lao Liu.

After the measurement of the last inch of the steel shaft was completed, Xu Guofang and Lao Liu's tired faces finally showed a satisfied smile, and it was successful! A three-meter-long steel shaft, hand-polished through, with an error rate of less than 0.5%, is perfect for handmade products.

Ding Richang was confused by the land dispute between the British and the local people at these times, and the governor Wenshan did not agree with the Westernists' proposal of "mastering the skills of the Yi to control the Yi", so he did not support the Mawei Ship Master School, and many of these Manchu ministers thought that it was better to build a ship than to buy a ship.

He was thinking about how to continue to apply to the imperial court for the full allocation of funds for the shipyard to carry out some necessary technical transformation of the shipyard equipment, at this time, there was a voice from Sun Fu asking to see him, and he was naturally very concerned about Qin Kai's new mechanical grinder, and specially instructed Master Sun to pay attention to the progress at any time and report daily.

After a while, Sun Fu hurriedly came in, gave a big gift when he came in, and said excitedly: "My lord, Qin Kai has been working there for almost a month, I will bring you good news today, and tomorrow I will have a final assembly test." ”

"Oh! Which spindle is made? Obviously, Ding Richang always paid attention to the movements in the shipyard.

"Yes, my lord, it was done a few days ago, I went to the shipyard again today, Qin Kai is assembling and testing the grinder, he said it himself, he will test it tomorrow!"

This night, the shipyard's machine tool workshop was brightly lit, this epoch-making machine tool has entered the final assembly, although Qin Kai is full of confidence, but also full of expectations, and for Xu Guofang, this is the first time that their workshop has produced a machine tool that can produce machine qì, naturally very excited.

Xu Guofang and a few apprentices were busy assembling the parts according to the drawings, while Qin Kai carefully checked the drawings on the side, for fear that there would be a mistake and affect tomorrow's test machine.

Suddenly, Xu Guofang ran over with a gear assembly and said, "My lord, there seems to be a problem with this group of parts, I see that the gear bite is a little insufficient!" ”,

Qin Kai took the component, called up the hologram of the machine tool and compared it, and sure enough, he found that one of the main gears did have the problem that Xu Guofang said, this kind of lack of occlusion, for a high-speed machine tool, it is very likely to cause the collapse of the entire component.

Qin Kai pointed to the big gear and said, "Old Xu, there is a bit of a problem with the cogging workmanship of this gear, you see, it needs to be reprocessed!" ”

Xu Guofang found that there was a problem with this gear set, it was because of his own feel when assembling, he didn't expect Qin Kai to find the key to the problem so quickly, and after taking the drawings of the big gear and measuring it, he found that it was indeed a problem with the tooth groove, and he was even more admirable in his heart.

The assembly progress of the grinding machine is not fast, but what makes Qin Kai very relieved is that the craftsmen brought by Xu Guofang are undoubtedly very outstanding in this era, and the small defects on the parts are quickly discovered and solved.

Seeing that the hands on his watch pointed to three o'clock in the morning, after hanging the transmission belt, the machine tool was driven by the power of the steam engine, and the test machine was a one-time success.

The first test product was Xu Guofang's carefully made steel shaft, which is a key component of the mechanical grinding machine, and due to wear and tear considerations, Qin Kai naturally wanted to have enough spare parts.

The head and tail of a steel rod are fixed on the workpiece frame, and the whole workpiece frame can reciprocate under the control of the steel shaft, and the grinding head of high-speed operation is fixed on the column, forming a fixed position for the grinding part.

After more than an hour of grinding, the first steel shaft completely completed by mechanical grinding rolled off the assembly line, at this time, except for Qin Kai and Xu Guofang, other craftsmen were arranged to rest, after all, there are more parts production work to be carried out tomorrow. Xu Guofang excitedly removed the polished steel shaft and took the ruler to measure it bit by bit.

After measuring for half an hour, he let out a long sigh of relief, and arched his hand towards Qin Kai and said, "Congratulations, my lord, I measured it, and the outer diameter of this steel shaft is almost no different from the one in use now!" Adults are really geniuses, you can polish one in this hour, and if you polish it by hand, it will take at least 10 days, and it will take a lot of luck. ”

Qin Kai patted him on the shoulder and said with a sincere smile: "Lao Xu, this is thanks to your craftsmanship, but this machine tool still needs to be tested, and you need to worry more!" He naturally understands that he can still be competent in drawing drawings based on gourds, and if he wants to make pieces of steel into parts, ten of them are not as good as this Xu Guofang.

"My lord, you don't have to worry about this, you can do research with peace of mind, how can you come to these rough jobs," Xu Guofang responded loudly with his red eyes that stayed up all night, and saw that the sky outside was already slightly bright, and the two of them each found a place to lie down for a while.

The sky was just dawning, Qin Kai was still sleeping at this time, more than 20 hours of continuous work yesterday, today naturally I have to add a little, in his sleep when he was tasting the food of the future generations, but he heard an inopportune shouting, and after trying to open his eyes, he found that the face in front of him seemed familiar.

"Qin Kai, Qin Kai," the person who came seemed to be very happy.

This...... Isn't it Master Sun, Qin Kai had just woken up, his brain was a little short-circuited, and it took him half a minute to wake up, and he hurriedly got up, "Master Sun, why are you here?" ”

Sun Fu looked very good, and happily pulled Qin Kai's arm, "Go and wash up, Lord Ding is in the workshop, I have seen the steel shaft you tried to polish just now, my lord is very happy!" ”

Qin Kai hurriedly rushed to the door, rinsed it with well water, cleaned up his clothes, and followed Sun Fu straight to the workshop.

The mechanical grinder was already in motion at this time, Xu Guofang was holding a ruler next to him and carefully measuring another steel shaft that had just been polished, and Governor Ding Richang also noticed that Qin Kai was coming and beckoned to him.

"Qin Kai, I've seen this polishing steel shaft, it's very good, but how to polish the cannon chamber, you can show me!" Ding Richang's old face was full of red light, he just listened to Xu Guofang's introduction, the efficiency of this mechanical grinder is 100 times more than that of manual work, if this grinder is used in the production of cannons, this is an amazing innovation.

"My lord, now this is an external grinder, because the grinding head hits the outside, you only need to hit the grinding head on the steel shaft column, and the barrel is fixed on the machine tool, it is the internal grinder, but now I don't have a gun barrel here for grinding, if you modify it, it only takes an hour to complete!" Qin Kai arched his hand and said.
