Time flies, and the years are like songs. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

Soon it was the month of Layue, the weather was even colder, and Yang He's quartermaster station made progress.

The lathe he needed and some parts and tools had already been made.

At this time, he was standing in the shop, steaming, the flames were blazing, a blacksmith was sweating profusely, he was busy, and it was still very comfortable to work in the armory shop in the cold winter, of course, it was very sinful in the summer.

"Tintin Dangdang ......"

The sound of hammers striking continued.

In the firearms shop, Blacksmith Yu and his son Yu Youtie, Blacksmith Li and his son Li Yougang, blacksmith Niu Jinliang and his son Niu Xiaozhuan all struck the pipe on the cast iron die, sparks flew everywhere, and the heat was overwhelming.

These old blacksmiths were led by Zhang Chuxun and Li Tiannan, and after the adjustment of this period in the village, it was no longer a problem to make the pipes.

The former exiled blacksmith Niu Jinting claimed that he was good at making armor and weapons, especially swords, and had a family handicraft, but for the time being, he still made firearms.

Seeing that they work very hard, it is obvious that Xin'anzhuang is their paradise, and the bonus system is also very attractive to them.

In particular, Yang He is not stingy with raw materials, and these blacksmiths make pipes, and they directly use fine iron.

This is very rare, and many guards and armory bureaus directly issue a pile of pig iron for you to slowly tap and forge.

It's a painful process, and fine iron is not easy to obtain, and wrought iron is not easy to obtain.

There are only two ways to obtain wrought iron, one is smelted directly in the furnace.

One is the so-called cast iron softening, in which pig iron is forged alive into mature iron.

Generally speaking, pig iron cannot be forged, but the ancestors have their own magic method, that is, as early as the Warring States Period, they thought of a solution: cast iron softening.

When the pig iron is heated to more than 1,000 degrees, the cast iron is close to the melting point and will soften into a semi-solid state, and it can be forged.

It's just that this method is very tiring, and it is necessary to forge the pig iron into mature iron first, and then forge the wrought iron into fine iron, that is, to make more good iron.

Many birds use forty catties of iron, which refers to this amount of pig iron, and they are forged to seven or eight catties of fine iron with cast iron softening, and the loss rate is amazing, and it is also surprisingly tired.

Therefore, the price of iron varies greatly, pig iron is only one and a half cents of silver per catty, wrought iron costs one dollar and three cents, and more iron is smelted and it costs six cents and six cents, and the labor costs are very different.

The village is happy, the system is attractive, and there are good materials, so why not work hard?

"Tintin Dangdang ......"

Blacksmith Yu and the others worked hard, all of them were happy, and they enjoyed their work very much.

Seeing that they all use steel cores to make cold bones, they keep knocking, and roll the hot thick fine iron into iron pipes, and the iron at the joints will be about an inch more, and the iron plate before striking is also small in the front and large in the back, which is because of the large pressure in the back.

Therefore, the gun tube is thick at one end and thin at the end, the thick one is the belly, and the thin one is the mouth, and the style is also octagonal.

When the reel closes, the seam will also be sprinkled with copper powder to make the seam more strong and friendly.

Looking at their efforts, Yang He nodded with satisfaction, the work is serious, the skills are in place, and the materials are sufficient and sophisticated, so there will be no problem with the quality of this firearm.

And because of the direct use of fine iron, within a day, each blacksmith and assistant can basically make one or two guns per person, and in the future, when their apprentices and apprentices slowly get started, they can have more.

After the control of standards and measuring tools, the length, caliber and quality of their guns are basically the same.

After the rough embryo of the gun tube was made, it was sent to Zhang Chuxun and Li Tiannan, drilling, polishing, and matching.

……

In front of me are two lathes, very long horizontal type, most of which are made of thick wood, but the trough is clad with iron, which is more durable.

One end of the bed is fixed with a drill pipe, and behind it is a large crank handle, which can actually be removed, and when you want to put it on, you can tighten it with a bolt.

At the other end is a movable ironwood platform with a tube that can be fixed in the middle.

"Let's get started!"

After looking at the rough lathe for a while, Yang He commanded.

Zhang Chuxun and Li Tiannan hurriedly responded, and each took a gun pipe and fixed it in the middle of the iron and wood platform, and the hole of the gun pipe was facing the drill pipe.

Then the front end of the drill pipe is the single-sided drill bit of Sugang.

Zhang Chuxun and Li Tiannan were both a little nervous, and according to Yang He's instructions, they each took out the vegetable oil filled with cooling oil from the tank and put it on the drill bit, and then Zhang Chugong and Zhang Chujing each held the rocker handle and shook the drill pipe of the two lathes.

The drill pipe rotated slowly, and because of the sesame oil as lubricating oil, the sound was still very small.

Yang He instructed the two to pay attention to a constant speed, and then under his command, Zhang Chuxun and Li Tiannan each pushed the moving ironwood platform, slowly moved the fixed gun pipe, leaned towards the drill bit, and finally drilled into it, and began to drill slowly.

Yang He asked the two to pay attention to the situation of the drill bit, because a lot of heat will be generated due to friction when drilling, even if the steel village material is used, if you continue to drill at this time, it will also damage the tool.

The traditional practice is to wait for cooling, or even use a damp cloth, here is to move the hose back, the drill bit is exposed, and continue to coat the cooling oil, which also has some lubricating oil.

Then continue to drill, just keep soaking the cooling oil, about three hours or so, a pipe is finished, and the quality is very perfect, quite a mirror effect.

took out the gun tube to watch, Zhang Chuxun and the others were all amazed, and it seemed that since following Yang Xianggong, it was an endless surprise.

Yang He also picked up a gun tube and looked at it carefully, he was very satisfied, this speed, this quality, not to mention in Daming, is the first in the world.

The only pity is that there is no better steel with cooling oil, otherwise it will not take half an hour to drill a barrel.

Everyone looked around, they were very happy, and at the same time, Li Tiannan felt that with this lathe tool, it seemed that the drilling skills were greatly reduced, especially shaking the drill pipe, it seemed to ......

He plucked up his courage and said to Yang He that his younger brother Li Tianxi and sister Li Zhuniang also knew some things about the drill bore crank, and when they were usually in their hometown, the two of them helped him, I don't know if they can transfer the rocker?

Yang He said happily: "Okay, let the two of them come over and shake the handle, and give them the treatment of an intermediate technician." ”

With the lathe, shaking the drill pipe is more of an assistant's role, and the two of them know this aspect of things, and it is no problem to come over and shake the handle.

It also happened to liberate Zhang Zhugong and Zhang Zhujing to do other things.

After drilling, the following is the assembly of various parts, many of which need to use standard parts such as bolts, because the plate teeth and taps are made, this aspect is too easy, especially the quality standards are the same, and Zhang Chuxun and others feel that it is so easy and convenient to make bird guns for the first time.

……

There are also yin and yang machines and copper bolts in the key parts of Xin'an, which need to be carefully polished by the master, but unfortunately there are too few blacksmiths in Zhuangzhong, which is an important factor restricting the production of firearms.

However, there is still a production of more than 100 strokes per month.

These spare parts have been made by Zhang Chuxun and others one after another, and the completed guns and pipes have been tested, assembled one by one, and finally completed.

On the shooting range of the munitions, Yang He looked at the Xin'an gun in his hand, and when he held it in his hand, he could feel that it was sophisticated.

The swan-neck style of the gun holder is conducive to holding and aiming close to the cheek, and the fire rope is installed in the arquebus, which is no longer in the way, and the automatic opening and closing of the fire door device is not afraid of the strong wind blowing away the primer.

The body of the gun is coated with lacquer, with good luster, the uniform standard of each part, the basic tolerance is very small, and the polishing is very smooth.

There is also a copper bolt at the back, which is tightly plugged and pushed and pulled freely.

"Not bad."

Yang He nodded with satisfaction.

Although it has not been specifically tested, it is certain that the firearm in the hand has a shooting life of more than 4,000 rounds.

Especially now that the caliber standard is the same, the quality is almost the same, and the bore pressure of each gun is the same, you can use the fixed cartridge ammunition, and the complexity of this logistics will be greatly reduced in the future.

Everything was perfect, the only drawback, it was too expensive.

According to rough estimates, the cost of making a new gun is about eight to ten taels of silver.

The cost would scare off a large number of people, but Yang He thought it was well worth it.

He is not one of those short-sighted officials and warlords, his eight to ten taels of silver Xin'an gun has a lifespan of more than 4,000 rounds, and the soldiers can also fight and use it at ease on the battlefield, and maximize the power of firearms.

However, the bird guns used by many officers and soldiers cost two or three dollars, which is cheap, but the life span is only 30 rounds, and they are still blown up at every turn.

It's only five times the cost, but there is a quality gap of more than 100 times, and a fool only uses two, two, or three dollars of goods.

"In the future, Xin'an Gong will be powerful in the world!"

Yang He thought with satisfaction, choked, and pulled the copper bolt in his hand. (To be continued.) )
