Just when the Yang family and the Bai family were planning their own plans at a slow pace in this era, Chen Xian was busy in the shop.

In order to control the overall weight of the cloth face armor and not crush the fourteen or fifteen-year-old half-grown teenagers under his command, Chen Xian stipulated that the maximum thickness of the armor should not exceed 2 mm.

At the same time, in order to ensure that there are no too weak areas on the nail plate, he also stipulates that the minimum thickness of the nail plate should not exceed 1.5 mm.

In order to facilitate the control of the thickness of the nail piece, Chen Xian required that the final stage of the nail piece must be cold forged with a small flat hammer.

In fact, because the material used is wrought iron, the strength of the material is not large, so it is not difficult to use the cold forging method.

The reason why cold forging is chosen is because of the hot forging wrought iron sheet, a light hammer down, it is possible to cause a great change in thickness, it is difficult to control the accuracy, small hammer cold forging is just the opposite, the effect of each vertical is very small, it is easier to control the thickness.

In order to ensure the uniform thickness of the iron armor, Chen Xian made a simple inspection tool for the apprentices to test the thickness.

He threaded a planed strip of wood through two pins on a flat surface of wood that was also planed.

During the inspection, the nail piece is stuffed between the wooden board and the wood plane, the wooden board on it is gently pressed, and then the gap between the wooden board and the nail piece is checked and measured with a uniform thickness plug gauge made in advance, so as to roughly judge whether the thickness of the nail piece meets the requirements.

Of course, this kind of judgment error is relatively large, and it can only be said that it is roughly controlled, and in order to obtain a large number of uniform thickness and thickness of the nail sheet, it is necessary to develop a qualified rolling mill.

After the thickness of the cold-forged nail is checked, it is handed over to an apprentice who will operate the iron shears, who will cut the edges of the nail according to the specifications.

After trimming, the nail piece is riveted by a special drilling apprentice with a hand crank drill.

After drilling, a special team uses a file to polish and deburr the edges.

Finally, the processed nail piece will be smoldered carburizing and quenching.

Chen Xian threaded the nail pieces with iron bars, mixed them with toner and lime powder, put them in a clay pot and sealed them, put them in a furnace for a long time to heat and smolder, and finally took out the whole string and quenched it as a whole.

After smoldering carburizing and quenching, the nail piece changes from iron to steel, and the hardness of the nail plate increases significantly.

When Chen Xian was opening a farmhouse, he was curious to do some cold weapon tests.

In the test, he found that the same bow, the same starting weight, the same distance, and the same material hardness of the arrow can easily shoot through two millimeters of soft iron, but not one millimeter of medium carbon steel plate, which shows that the hardness of the armor has a huge impact on the defense of the armor.

……

Half a month after recruiting the new apprentices of the Bai family, more than 30 pieces of linen cloth cloth fabrics that Chen Xian had ordered in several tailor shops were also delivered one after another.

Chen Xian led the apprentices to rivet the made armor pieces onto the cloth.

He asked the apprentices to draw the nail on the cloth with chalk, and after determining the position of the nail piece, he used chalk to draw the riveting position.

The next thing is to rivet the nail piece to the cloth surface according to the chalk arrangement, this work is much simpler than the preparation of the armor, a cloth surface armor is only one or two hundred nail pieces, and the riveting of copper nails is much simpler than a piece of armor, and the relative workload is seven or eight times less.

After the first piece of cloth armor was made, Chen Xian personally tried it on, and he found that the weight of this cloth armor was slightly lighter than his armor, and the difference in flexibility seemed to be, the biggest advantage of this armor was that it was simple to make, cost-effective, and its performance was actually not better than that of Zaga.

In addition to flexibility and comfort, Chen Xian also tested the protective ability of the cloth mask armor with a wooden dummy.

Experiments have shown that the protective power of this armor is not inferior to that of piercing armor.

In general, this armor is considered unsatisfactory and can only be used as a transitional armor equipment.

……

It took more than half a month for Chen Xian to finally equip all the young apprentices with cloth face armor.

In order not to let people find out that these thick clothes were actually iron armor, Chen Xian asked the apprentices to sew another layer of thin linen cloth on the arms of the cloth armor that exposed the iron armor to cover the iron armor.

After completing the armor, Chen Xian immediately added the armor to the emergency response training, and he asked the old apprentices to wear the armor when they heard the whistle of the emergency assembly, and when they gathered according to the plan or entered the predetermined post.

In order to increase the speed of emergency response, Chen Xian formulated detailed military regulations, where to place the armor when working or before sleeping, in what way and in what order, where to place the weapons, in what order and manner to place the armor and weapons, and even in what posture to take the weapons......

The rules and regulations are as specific as possible to each step, and then let the apprentices train repeatedly according to the regulations, and then go back and revise the details of the rules and regulations again and again during the training......

It is also thanks to Chen Xian's high prestige and even worship among the old apprentices that the apprentices can willingly carry out this seemingly boring training.

These details and training have allowed this group of teenagers to gradually have the miraculous reaction speed and efficiency of this era.

Just when Chen Xian was secretly creating efficiency in his shop that people in this era could not understand, Bai Yuanwai's plan was also progressing in an orderly manner according to the slow pace of this era.

While Chen Xian was busy developing cloth face armor for the teenagers under him, he was still thinking about another matter.

He wanted to build a small Zhuangzi on the land that Yang Yuan gave him.

When Chen Xian realized that the katana was likely to cause him trouble, he felt that he was staying in Dongzhuangzi, like a turtle in an urn, and he couldn't even escape in case of an irresistible disaster.

That's why he went to get his own five or six semi-automatic.

But this did not give him a sense of security, although the five or six semi-automatic was powerful, after all, there were only more than thirty bullets.

Chen Xian felt that the best way was to establish a small Zhuangzi of his own outside of the East Zhuangzi.

Of course, there are more important reasons why he wants to build a small Zhuangzi outside the Zhuangzi.

Chen Xian wanted to try to set up a series of hydraulic forging workshops, but this idea did not work in the East Zhuangzi, where there was no river.

Water power is the beginning of human beings using natural energy, and in this era, water power is also the only natural energy that Chen Xian can use in addition to human and animal power.

Fortunately, in the farmland that Chen Xian exchanged for plate armor from Yang Yuanwai, there happened to be a small river called Beigou passing through it.

Yiyuan is a mountain plain, the terrain is lower than the surrounding mountains, there are dozens of large and small rivers flowing into the plain on the surrounding mountains, and finally converge on the plain Yishui River, the name of Yiyuan comes from this.

Beigou is one of these inconspicuous rivers, the small river is not big, but if a small reservoir can be built, it is still no problem to drive a few water wheels.

However, with the resources that Chen Xian currently has, if he wants to build a small Zhuangzi, he still can't do it.

If he wants to build a new Zhuangzi, Chen Xian must rely on the Yang family or the Bai family.

But neither the Yang family nor the Bai family will sit idly by and watch him go out independently, let alone help him build a new Zhuangzi.

If you want to get Yang Bai and the two families to agree, and help him outside the East Zhuangzi, within the influence of the Yang and Bai families, to start another small Zhuangzi, it is almost the same as the guest wants to break up with the host, and the host wants to help him build a house, it is absolutely whimsical.
