In fact, the engraving of printed drawings is usually carefully carved out of lead, and it takes a lot of effort to make, not to mention, after using it once, it is useless, and it can only be re-refined;

Zhao Dagui is equivalent to using spiritual gold to make engraving plates for printing, which seems to be extravagant and expensive, but it can be made instantly, and it can be used repeatedly, which is extremely convenient.

According to the above operations, Zhao Dagui obtained the design drawings and standard models of the machine tool screws, which can also be printed with a printing press in the main world.

Zhao Dagui didn't take much effort to do all this, and it only took a few minutes before and after, which took seven or eight hours to draw drawings compared to ordinary skilled cartographers, I don't know how many times faster.

Zhao Dagui then followed the above process to continue to make the design drawings and models of other components in the machine tool, and it took half a day to finally get out the design drawings and models of all the components in a machine tool.

In this way, Zhao Dagui's main god space used the made part model to assemble a machine tool with extremely high precision;

There is also a complete set of shooting drawings for all the parts of the lathe, the one in the main god's library, which can be kept for oneself, and the set printed with a printing press in the main world can be placed in the database for backup, or it can be used by other engineers or designers to look through and learn from.

After Zhao Dagui mastered the ability of "micron-level dimensional control", he quickly used this ability to make design drawings of countless objects such as machine tools, steam engines, and ship parts, many of which also used spiritual gold to show models and assemble them in the main god space.

In the project team of imitation silk reeling equipment, Sheldon is a real scholar, learning mechanical design very fast, many people think that his design ability can surpass Chen Fan, a seasoned engineer with decades of experience, within a year.

However, even with Sheldon's mathematical talent and employment level, his progress in design is much worse than Zhao Dagui's, not because Zhao Dagui's learning ability is stronger than Sheldon's, but because he has the same ability as the above-mentioned cheating.

Drawing drawings is also the basic ability of engineers, when Sheldon drew hundreds of design drawings at most, Zhao Dagui has drawn thousands or even tens of thousands of design drawings, and has also fiddled with countless mechanical models, and is familiar with machine tools and even various machinery and equipment, so that he is truly familiar with it.

Through a period of drawing and contact, and with the help of the memory aid ability of the main god library, Zhao Dagui's cognition of the mechanical equipment of this era has improved at a very terrifying rate, and he has an understanding of various machine tools and steam engines in shipyards, as well as the mechanical equipment structure of steamships such as the Dongfang, which is not inferior to that of most engineers.

Although this does not mean that Zhao Dagui has become an outstanding designer, after all, it is more a test of people's innovation ability and mathematical ability, but at least it shows that Zhao Dagui can be called a very good engineer, or the kind with very solid basic skills.

After having enough accumulation, Zhao Dagui can draw a full set of design drawings for the iron-hulled propeller steamship Oriental, and then use spiritual gold to make a 100:1 scale model in the main god space, and Zhao Dagui's engineering design ability will have a leap at that time.

Because of the limitation of machining ability, even if a full set of design drawings is made, it may not be possible to produce a practical steamship, but at least in terms of design skills, the gap between Zhao Dagui and the first-class ship designers of this era will be narrowed to a very small extent.

In the next period of time, Zhao Dagui was immersed in the pleasure of rapidly improving his design ability, and he couldn't wait to pounce on this aspect of learning every day, but unfortunately there were a lot of commercial affairs to deal with, and drawing design drawings and making models were actually very consuming mental power, and he had to replenish them with blood nerve true qi seeds from time to time, and he couldn't draw them around the clock, which made him feel very regretful.

In addition to learning mechanical design and compacting the foundation, Zhao Dagui had to be busy with the design of equipment such as steam engines and silk reeling machines, which was a good opportunity to actually test his design ability.

In fact, there were only three people who were the main force in designing the reeling equipment, Zhao Dagui, Chen Fan, and Sheldun, and the other three engineers lacked sufficient knowledge reserves, and at most they made some suggestions or started to do so; other scholars and workers were even more unbearable, and they were not even qualified to do so, so they could only study frantically and try to keep up with the progress of Zhao Dagui and others.

However, after all, the silk reeling machine is a relatively simple machine, and it is not much difficult to use the machine to complete the things that Chinese farmers can do by supporting their own pots.

It's just because most people have never been exposed to Western machinery that they find it very difficult at first.

After checking all kinds of technical information, after a period of busy work, the design of the silk reeling machine gradually became a little eyebrow.

However, after work, you also have to rest, and after a few days, on the Sunday that foreigners say, Zhao Dagui's commercial houses, colleges and factories all have a day off as usual.

One day off every seven days is extremely normal in the future, but at this time period, it seems to be very maverick, and the general business house is one day off every ten days, and more often than not, it is not allowed to rest at all.

Sheldon, who has been following Zhao Dagui to study silk reeling equipment, finally has time to rest, and by the way, he meets his friend Yang Willy, who he hasn't seen for a long time.

Shelton and Yang Willy are both from Wangxia County, and the two families have been close to each other since a long time ago, and in this generation, both of them are interested in Western studies, and they are equally intelligent, so they naturally become friends.

Zhao Dagui once called the two good friends, but Sheldon read a lot of books, and he didn't know the allusion to this.

During this time, Sheldon learned "Introduction to Mechanical Drawing", and tried to learn the design of Western machinery, imitating the silk reeling equipment of foreigners, and the rapid progress of Western learning can be described as very busy, watching his good friend Yang Willy go on the "wrong path" and failed to correct it, so I want to take advantage of the time now, and Yang Willy to nag and nag.

It turned out that Zhao Dagui invited a group of foreigners to come over, and he wanted to do some discipline training, and bombed all the craftsmen and staff who had nothing to do under him, so that the foreigners could take a good look at it, and asked the scholars of the Oriental Academy if they were interested.

This kind of thing, but anyone with a normal brain knows to avoid it, but Yang Willy doesn't know what kind of wind he smoked, so he followed seven or eight young scholars to participate in the so-called discipline training, and crawled on the ground with those craftsmen every day, which can be described as sweeping the floor.

"I heard that someone has been crawling on the ground all the time lately, like a mud monkey, but when I saw it today, it was quite clean. ”

"I heard that someone always hid in the house and read a book, and didn't bask in the sun for a whole month, and his face turned a lot whiter. ”

The two of them found a teahouse in the city to meet, and before they sat down, they didn't forget to hurt each other, and then looked at each other and laughed.

Sheldon thought that Yang Weili had suffered a lot outside the city during this time, and he should be embarrassed, but he didn't expect to see that the other party's body was clean, full of joy that he had never seen before, his face was more indescribably brighter, and there was a more vigorous and resolute atmosphere in his words and demeanor, and he couldn't help but be secretly surprised.
