[Chapter 240 Calipers]

Yan City.

When the new products of the Wangfu caused a sensation in Jinling, Zhao Xu was admiring Dasong’s first vernier caliper with Wang Ying in the Military Division.

The caliper is cast from pure steel and polished to a bright white finish.

There are even scales on the edge of the steel ruler.

After the first original ruler appeared, it was much easier to make marks with reference to the original ruler.

So after mastering the vernier caliper technology, the scale becomes a simple matter.

“Well, it’s pretty good.” Zhao Xu looked at the vernier caliper repeatedly, very satisfied, “Our war department needs a group of craftsmen who can do fine handwork, you have to take that into consideration.”

The accuracy that can be judged by the human eye is 0.2 mm.

Therefore, human beings can manually polish the workpieces whose accuracy is required to be within the error range of 0.2 mm.

The existence of the original ruler and vernier calipers depends on the accuracy of the human eye.

If some tools are provided to people, the accuracy can be improved.

He still remembers a contemporary news report that a certain aviation aircraft industry often needs manual polishing due to the small number of fighter parts, high processing precision and high difficulty.

The next fitter even improved the hand-grinding accuracy to three thousandths of a millimeter.

This shows that human potential is unlimited.

Of course, this is just an example, and this fitter can only do it with the help of a contemporary high-magnification electronic magnification lens.

He can’t provide such advanced tools.

However, after the glass comes out, a magnifying glass can still be considered.

With vernier calipers, there is a magnifying glass.

These craftsmen can make fine parts such as watches, and their level is sufficient.

“Yes, Your Highness, this original ruler and this vernier caliper were both made by a craftsman named Mo Wen.” Wang Ying said, “This official has already raised his monthly payment.”

Zhao Xu nodded, showing a funny look , “Mo Wen? The name is interesting.”

Wang Ying also laughed, “Speaking of which, I have to thank Zhou Yi. This Mo Wen is a Jinzhou craftsman, and he was a sculptor before.”

Just as he was talking, he saw a The craftsman passed in front of him, and immediately stopped, “Don’t ask, come here.”

Zhao Xu looked in the direction of Wang Ying’s finger, and saw a very short dark young man, only about 1.5 meters, walking towards him.

The young man’s face was naturally dull, and when he came in front of Zhao Xu, he bowed to Zhao Xu under Wang Ying’s reminder.

Then he lowered his head and said nothing.

“Excuse me.” Zhao Xu helped Mo Wen up.

He said: “Making the original ruler is a great achievement, what reward do you want?”

“My lord Wang is too small.” Mo Wen replied.

“Lord Wang is Lord Wang, and this king is this king. Today, this king is happy, so you can just say it.” Zhao Xu said with a smile.

After hearing this, Mo Wen glanced at Wang Ying, and saw Wang Ying nodded.

At this moment, his body suddenly twisted uncomfortably.

After hesitating for a while, he said: “The young one is black and short, and now he is still a bachelor at twenty-five. Can His Highness reward the young one with a wife?”

“Hahaha…” Wang Ying and Zhao Xu laughed at the same time.

Seeing this, Mo Wen thought the two were laughing at him, so he lowered his head again.

But what King Yan said immediately made him excited, “My lord, I will leave it to you to ask Mo Wen about marriage. This king will give you a month, not ten days. If you can’t do it, I’ll fine you one month’s salary.”

“Oh, Your Highness, I’ll hand it over to the subordinate officials, if you can’t do it, you can be fined for two months.” Wang Ying said with a smile.

Don’t be overjoyed, thank you again and again.

Zhao Xu joked: “But having a wife, you can’t delay the work of the military commander.”

“It’s definitely not going to happen.” Mo Wenhan laughed.

But Mo Wenti’s request reminded Zhao Xu.

This military battle division is the same as the monk temple.

The ancients emphasized that there are three kinds of unfilial piety, the greatest of which is having no descendants.

If this problem is not solved, some older craftsmen may not be able to concentrate on their work.

During this period of time, Zhou Yi has been sending the slaves he bought to the Military Division every now and then.

The man stayed in the Bingzhang Division, and the woman was temporarily placed for use according to his request.

Thinking of this, he said to Wang Ying: “It’s not just Mo Wen’s business, but also craftsmen who have reached the age and have no family will be arranged for them.”

The conversation between the two was clearly heard by the craftsmen working around.

They immediately beamed with joy and winked at each other.

It seems that he has strength to work.

When Wang Ying saw it, he gave a wry smile, “Your Highness still has a unique vision, why didn’t the lower officials think of this matter, as the saying goes, one can feel at ease when one has a family.” The

two exchanged a few more words.

Zhao Xu and Wang Ying went to the workshop where the crucible made steel.

The vernier caliper was made, and the problem of fine parts on the flintlock was solved.

But this is only one solution in a whole set of chains.

The boring tool for cutting the gun bore and the drill bit for drilling the gun barrel have not yet been found.

And this has to rely on high carbon steel.

This time he came to Bingzhang Division, besides checking the vernier calipers, the most important thing he did was to ask Wang Ying to refine high-carbon steel.

The hardness of steel varies with the carbon content.

The less carbon, the softer the steel, and vice versa, the harder.

In the crucible steelmaking method, adjusting the carbon content of steel only needs to adjust the ratio of pig iron and wrought iron.

Zhao Xu is clear about these ratios.

So he simply asked Wang Ying to fetch a pen and paper, and wrote three ratios on the paper.

The first ratio is the ratio of producing mild steel, the second is the ratio of medium carbon steel, and the third is the ratio of high carbon steel.

While writing, he explained the significance of carbon in steel.

Because Wang Ying was busy, he couldn’t go to the school to attend lectures in time every day, so he could only take the opportunity to popularize science with him.

“I see.” Wang Ying suddenly realized.

What Yan Wang told him was a key to turn the hardness of steel.

In the past, Bing Zhansi used medium carbon steel to make armor, weapons, and cannons.

At this time, he asked the craftsman to vacate a crucible and weigh it. He weighed the pig iron and wrought iron, and put them into the crucible according to the proportion to melt them.

Under the high temperature of coke, the iron block melts quickly.

When it is turned into pure molten steel and the impurities floating on it are removed, Wang Ying asked the craftsmen to pour the molten steel into the mold.

When it was not completely cooled, he asked the craftsman to forge it into an awl.

“Take a steel plate.” After the awl was finished, Wang Ying couldn’t wait to ask the craftsman to bring the steel plate.

Then he took a hammer himself and smashed the awl into the steel plate.

“Ding… nailing…” After a few soft sounds, the awl penetrated the steel plate.

Then he found an awl made of medium carbon steel and smashed it a few times. The tip of the awl was bent and only went in half.

Wang Ying was completely convinced by the facts in front of him.

He said: “Your Highness’s knowledge really impresses the officials.”

Zhao Xu looked slightly smug, and he was about to talk about using high carbon steel to make drills and boring tools.

At this time, the guards of the Bingzhang Division came to report that Tsui Hark had come.

Ordering the guards to let Tsui Hark in, Zhao Xu picked up a brush to draw the specifications of the drill bit.

Before drawing a few strokes, I heard Tsui Hark’s eager voice.

“Your Highness, something has happened. The officials have probably figured out the conspiracy of the Yuan family, Xue Pan and Zhu Rong. I’m afraid they will take action within two days.”
