Wang Zichao and Chen Fan are both old people, but when they saw this, they couldn't help but shake their heads, how could this machine, which is used to earn hundreds of thousands of taels or even millions of taels of silver, be so easy to make.

In any case, with Zhao Dagui's selection of 20 scholars and 20 workers from the Oriental Academy as the main force, the project of imitating Western steam engine silk reeling equipment has finally officially begun.

After deciding to start copying the steam engine silk reeling equipment, everyone found that one of the embarrassing things was that except for Chen Fan and the other three engineers who had basic mechanical drawing skills, could read and draw design drawings, and understood concepts such as errors and cross-sectional drawings, the others knew nothing about mechanical drawing.

Zhao Dagui is a science student in modern society, and has taken mechanical drawing and practical courses to some extent, but most of them have returned to teachers after graduation, and at most half of them can understand design drawings, and others include Sheldon, who is very good at mathematics, and he has no knowledge of these, and he doesn't even need to use vernier calipers.

If you don't have any knowledge of mechanical drawing, you can't understand and draw design drawings, and you can make simple machines just by describing them in words, but I always feel that it's not like that.

"Let's find a book on mechanical drawing, translate it, start with the basics, then make the design, and finally machine it. Zhao Dagui proposed a solution that was not a solution.

"It makes sense, we have so many Western books, we can learn them quickly. Sheldon said confidently.

Chen Fan couldn't wait to hold his forehead with his hand, although he said that he wanted to make a machine from scratch, but before he started to make a machine, he had to find a Western book on cartography, then translate, then study, then paint, and then start to study the reeling equipment, which was too thorough.

Since Chen Fan followed Zhao Dagui, he had always felt that this boss was terrifyingly shrewd, and he was suspicious of him for the first time at this time.

Wang Zichao and other scholars also felt that this matter was very unreliable, but they knew that they didn't understand anything, and they had no right to speak at all, so they could only let it go.

Zhao Dagui and Sheldon went to the library and rummaged through the books for two days before they found all the books on mechanical design and raw silk reeling equipment, a total of more than 30 books, all of which were brought to the project team.

Chen Fan knows some foreign languages, but he understands Portuguese, and he is not good at English, so he can only rely on Zhao Dagui and Sheldon for translation.

When Zhao Dagui was in modern times, mechanical drawing actually only studied for one semester, only twenty or thirty hours before and after, and drew a lot of complex tubing valve design drawings, which is also regarded as two knives, which shows that for people with basic knowledge of junior high school or above, it is not difficult to learn mechanical drawing, only to see whether they are familiar or not proficient.

Zhao Dagui compared the content of the modern version of the "Fundamentals of Mechanical Drawing in Universities" book in the main god library, and selected about 50 pages of content from these books, which was determined to be the content of the professor, including the use of measuring tools such as vernier calipers, scales, cross-sectional views, errors, etc., which should be enough for designing silk reeling equipment or something.

Zhao Dagui hired a number of people who were proficient in Chinese and English Chinese, such as missionaries and scholars from the Oriental Academy, to help him translate with Sheldon, and according to the explanation of the terms of modern books, finally unified the terminology, but in two or three days the textbook was compiled, and then began to teach to other scholars and workers.

This textbook book was named "Introduction to Mechanical Drawing" by Zhao Dagui, and after being translated into Chinese, the scholars of the project team first copied it and then studied it, and then borrowed the printing press of Maddox to print thousands of copies of the more than 50 pages of the book for more people to study.

Chen Fan and others learn mechanical drawing purely by accumulation of experience, and most of the knowledge is understood, but there are also some omissions, and they read books with relish;

Sheldon has always been a top student, who can teach calculus by himself, and is admired by mathematicians such as Gu Sheng and Li Xinlan, who has mastered all the points after reading the book once;

However, Wang Zichao and others did not have a sufficient foundation in mathematics, and even came into contact with concepts such as millimeters, microns, and errors for the first time, and learned hard, but they could only grit their teeth and survive, and then draw various basic graphics under the professors of Chen Fan and others.

After a month or so of hellish training, everyone drew hundreds of drawings of mechanical parts, and they were barely able to get started in mechanical drawing, and they were qualified to learn more about mechanical design, and they could also try to design the machinery needed for raw silk reeling.

Zhao Dagui also revisited mechanical drawing during this time, drawing various drawings every day, and consciously improved his ability in mechanical drawing, which was much stronger than the level of the two knives in modern society, so he decided to use one of his magical powers, or golden fingers.

In fact, for Zhao Dagui to learn mechanical drawing is very important, than the so-called raw silk reeling equipment development is much more important, after all, even if the reeling silk factory is established, that is, to make more money, but mechanical drawing is really to open the door to the mechanical world, the significance is extraordinary.

When he went to Hong Kong before, Zhao Dagui bought a high-precision copper ruler and a spiral micrometer and an angle measuring instrument invented by Watt, and finally brought them back to Shanghai to treasure.

On this night, Zhao Dagui brought all these high-precision measuring instruments purchased at a great price back to his room, and told his family that unless there was really a big thing, he should not come over to disturb him.

Sitting on the sofa in the room, Zhao Dagui pondered for a while before deciding to put his long-standing plan into practice.

As the successor of the previous main god, Zhao Dagui has obtained very few magical powers, and the most important special ability is to convert gold into spirit gold, and then use his mind to command the spirit gold to change various shapes.

Although this ability had saved Zhao Dagui's life before, allowing him to avoid Deng Xian's Blood Shadow Divine Finger, and then killing the other party in turn, but overall, it was pitifully thin.

However, after this period of exploration, Zhao Dagui has explored many ways to use spiritual gold, which can be roughly divided into five functions: "rubbing", "copying", "embodiment", "writing" and "printing".

The function of "rubbing" is well understood, which is to form a mold of a certain real object.

For example, if you want to rub a pencil and other solids, Zhao Dagui can use the spirit gold to wrap the pencil firmly, and then withdraw the spirit gold into his body (the pencil is still in the main world), and he can form a hollow spirit gold nugget in the main god space, in which the hollow part is highly consistent with the shape of the original pencil.

"Copying" is also very easy to understand, punch a hole in the spirit gold nugget formed by rubbing, then inject the spirit gold into it, fill the rubbing mold (but do not fuse it with the rubbing mold), and then withdraw the rubbing mold, you can get the spirit gold nugget that is exactly the same as the original rubbing entity.

Using the rubbing function and copy function, Zhao Dagui can use spirit gold to copy the shape of any solid in reality.

The function of "embodiment" is to use the characteristic of changing the shape of the spiritual gold nugget with your mind after seeing a certain object, and use the spiritual gold to simulate the shape of the object.

However, this is the same as a sculptor carving an object out of stone, there can be a large error, and it may be fine as a work of art, but the actual industrial value is very low.
