1. Standardization

Even if Wang Youzhen didn't hear the ridicule of Wang Youzhen with his own ears, he had already predicted it.

Whether it is the ridicule of the shopkeeper Qingshou or the rumor that was circulating in the middle of the night.

Wang Youzhen didn't care at all. His only idea now was to quickly return to the Industrial Academy to find his eldest disciple Jiao Xu.

The eldest disciple Jiao Xu has been creating a new flintlock rifle for a while.

The flintlock rifle he built from small parts with his own hands is very different from the flintlock rifle transformed on the original basis.

In addition, after this period of study on mathematics, physics and chemistry, Jiao Xu has had many new ideas and is making some new inventions, but he just doesn’t know what the results are now.

Wang Youzhen walked back to the Industrial Academy, and the north facing south was his own independent yard.

Two rows of small yards were built on both sides of the Industrial Academy, which was designed to be used by future talents.

When Wang Youzhen came to the small courtyard where his eldest disciple Jiao Xu was, the most eye-catching thing was a house.

There are stoves, bellows, chopping boards and other utensils used to create flintlock rifles, which look very much like a blacksmith shop.

But it is much bigger than an average blacksmith shop.

In Wang Youzhen's opinion, it looks more like a factory workshop, after all, there is a large Ming Dynasty drilling machine inside.

This Ming Dynasty drilling machine was used to trim the chamber of the flintlock rifle. When Wang Youzhen first saw this drilling machine, he was really amazing.

The drilling machine uses wood as a frame, and the circular stone plate is used as an inertia wheel. After being tied to a pierced strip, it is pulled by human force to make the stone plate drive the drill bit to rotate.

The only disadvantage is that the drill bits and stuttering knives should be made of hard steel, and the steel is made of fallen steel, which is relatively soft, so half of the time it takes to make bird guns to drill and scrape the gun.

To put it bluntly, the drill bit should be made of high-carbon steel, rather than softer low-carbon steel.

Wang Youzhen walked into the Jiangzuo room. It was already autumn when the weather turned colder, and there were still a wave of heat coming towards him.

Jiao Xu is building a flintlock rifle, using a three-stage joint type.

The method is to make the gun barrel first, and the gun barrel is made into pieces with cooked iron, usually two or three sections, and finally welded into one.

The first step is to control the pipe.

Jiao Xu picked up a steel core of a slender cylinder to make cold bones.

First burn the cooked iron made from the gun tube until red hot, and then take out the blank that burns to a certain temperature.

Chief Jiao used a hammer to knock the hot cracked iron outside the steel core and rolled it into an iron pipe.

During the process of wrapping iron, the steel core is constantly extracted and cooled with water to prevent the steel core from being welded together with the dry iron.

The rolled iron pipe should be slightly thicker so that the gun pipe can be strong and withstand multiple consecutive firings.

The second step is welding.

Since long guns above three feet are welded one after another, guns that are not welded are easy to explode and bore.

The head of the Jiao clan and other gunsmiths regarded whether the gun barrel was welded perfectly as the key to the success or failure of the gun making.

Wang Youzhen was clear about this point. As early as the mid-Ming Dynasty, when the Japanese pirates invaded, the Ming army craftsmen took advantage of tricks and caused many accidents.

These are even recorded in "Ji Xiao New Book": "Recently, there have been few people who have suffered from illness, but they do not complain about it. Ren Zhen instructed the craftsmen to roll it into an iron tube, with uneven thickness and thickness... and even single tubes are rolled into a single tube, and they will be damaged after being lifted."

Wang Youzhen stood in the room, staring at Jiao Xu and the leader of Jiao clan to build a flintlock rifle, and watched it for a full day.

During this process, Wang Youzhen discovered something that surprised him very much.

Jiao Xu was actually using something similar to a vernier caliper and micrometer.

Could it be that there were vernier calipers and micrometers in ancient times?

With doubts in mind, Wang Youzhen walked to Jiao Xu and Mr. Jiao squatted in the open space to have dinner together.

Wang Youzhen took a few bites of the pancake and couldn't help asking: "The two measuring tools I just used are vernier calipers and micrometers?"

What surprised Wang Youzhen was that Jiao Xu swallowed the fat meat in his mouth, smiled stiffly, and actually gave a positive reply: "Yes."

The head of the Jiao tribe who was also squatting beside him saw his grandson's appearance and was so angry that he almost slapped his grandson in the head.

Now, no one knows that Wang Youzhen is actually the master of the three villages and the young gentleman they admire.

The young man took the initiative to ask questions, but he quickly said something nice to bring the relationship between the man and his disciple closer.

Although Jiao Xu is already Wang Youzhen's eldest disciple, he is so close that he can't be kissed anymore, which is basically equivalent to his son.

But recently another Bo Jue came, and maybe he would accept more disciples in the future.

If there is only one son in the family, all the favor must be on that son.

If there are too many children at home, if you want to get the attention of your parents, you have to compete for favor.

In addition, since the Jiao clan leader knew the function of the vernier caliper and micrometer that his grandson invented, he was a gunsmith who had built bird guns for decades, he understood the function of these two things very well.

These two things can be said to have brought earth-shaking changes to the bird gun.

Clan Chief Jiao also understood his grandson's temper. He didn't like to talk much, and his nervous movements became stiff when he met people.

Clan Chief Jiao laughed and said actively: "These two things called vernier calipers and micrometers are made by my eldest grandson."

"It is used to mark......... what's the point."

When Chief Jiao said this, he suddenly got stuck because this was a new word he had never heard of.

At that time, he said it from his grandson Jiao Xu and didn't take it seriously. He forgot after hearing it once.

Wang Youzhen stared at Jiao Xu with his eyes, which was quite bright: "Standardization."

“Yes, yes.”

Clan Chief Jiao slapped his head suddenly and grinned, "It's this standardization."

The Jiao clan elder was afraid that Wang Youzhen would not understand the power of standardization, so he quickly explained: "With this standardization, the diameter of my eldest grandson and the diameter of the lead bullet can be established."

"To put it bluntly, it means turning the muzzle size of the flintlock rifle and the size of the lead bullet into the same shape."

When Chief Jiao said this, he looked back at Wang Youzhen.

Seeing that he did not show a shocked expression, he felt a little disappointed.

But it doesn't matter. Mr. I don't know how these two subtle changes will bring to the flintlock rifle.

The head of the Jiao clan pushed his grandson Jiao Xu, who was there, just eating stiffly, but still kept silent.

Clan Chief Jiao could only introduce himself: "Sir, don't underestimate these two changes that sound small, as they have played a huge role."
