The end of the Ming Dynasty swept the world

Chapter 418 Forging and Modeling
The next day Ding Yi brought a spring wheel gun to meet Zhou Dahu and his wife, Li Zhongyi and others, and summoned twenty master craftsmen under his rule.

Ding Yi now has nearly 6000 craftsmen and workers. Since the beginning of last year, they have been graded according to their level. At present, only 20 people can be called master craftsmen, all of whom are first-class craftsmen with superb skills.

Different grades, wages and housing conditions and the number of fields are different, which also motivates everyone to study hard and improve their own level.

Because the number of places is unlimited, there is no need to compete, including the master craftsmen of the school, who are willing to pass on the technology to others, and there are rich rewards for master craftsmen who teach master craftsmen.

So in the past few years, Ding Yi's own training of craftsmen has been relatively smooth, and several new craftsmen appear every year.

In the morning, many craftsmen gathered around to look at this first-class wheel-wheel gun in Europe in turn.

This is made by a European watchmaker. The craftsmanship is absolutely exquisite, and each part is extremely delicate. Because of this, it is relatively delicate. Generally, it will be polluted and corroded after a dozen shots.

Ding Yi drank his tea without making a sound, just watching everyone take turns watching.

The craftsmen whispered to each other while watching, because it was the same way when they usually discussed skills, Mr. Ding didn't allow everyone to hide under their armpits, and discussed everything together.

The craftsmen in Lushun will not hide now, because many of them came to Lushun and found that their sons and grandchildren no longer need to be craftsmen. Some time ago, there were several sons of craftsmen who were sent to Jeju Island is the chief civil servant, which is no better than craftsmen.

Therefore, the craftsmen did not hide the technology they taught at all, unlike craftsmen in other places in the Ming Dynasty.

The blunderbuss was passed around and watched for nearly half an hour, everyone looked at it for a while.

Someone wanted to dismantle it on the spot, but was stopped, Zhou Dahu said: "I will call all the craftsmen later, and have a look at them again. There are many people and strength. In the words of Mr. Ding, it's time to brainstorm."

Li Zhongyi laughed: "Dahu, you can do it, now you can learn to speak like Master Ding."

Zhou Dahu's face flushed red: "I'm not wrong, am I?"

"Hahaha." Everyone shouted in unison.

After looking around, it's time to start speaking.

A master craftsman named He Atie took the lead in speaking.

He used to be a blacksmith. Chongzhen went to Lushun for four years. At first he only knew how to forge iron, but later he started to learn how to shoot guns. One piece, that is, to temper iron into steel, which is used to make flintlock guns.

The steel he practiced is very good, which is very suitable for making flintlock guns, steel cannons, and Lumi guns.

"I just checked. The inside of the gun is a little corroded. Europeans use a lot of copper, so it must not be durable. I guess it will take ten guns to replace the parts."

Li Zhongyi immediately said: "Copper is soft, and the parts inside are very delicate. If steel is used, it may be a bit difficult."

"Improve gunpowder. Our gunpowder feels better than Europeans."

Ding Yi bought guns from Pilut one year, and Pilut also sent gunpowder and shells. Ding Yi brought them back for comparison, and it was not as good as his granular gunpowder.

"It will corrode even if it is improved, and it will definitely be the case with copper."

"Then make more parts and replace them at any time. I checked and found that the main reason is that the parts are corroded, and the gun body is not a big problem."

"Then you have to tell Mr. Ding that you can use an assembly line and standardize, so that you can strictly replace it."

There was a lot of chatter at the scene, and everyone talked freely, and finally came to a conclusion for Ding Yi, Lushun must be able to make it, and it depends on Ding Yi's requirements for range and power to decide what type to make.

Ding Yi thought for a while and said, when I came back, I tried the gun on the boat, and his gun can break through the iron armor within ten meters, but not ten meters away.

I want to use it for cavalry, for close combat. It is best to have a powerful range of 20 meters. It is not necessary to break the armor and kill the opponent. After hitting, the opponent's cavalry may also fall off the horse.

Moreover, not all the Houjin soldiers have iron armor.

The damage range reaches 20 meters. It seems a simple statistic. From the barrel, the amount of gunpowder, and the size of the lead bullet, the gun weight will definitely change.

In Ding Yi's words, it doesn't matter if our guns are heavier or bigger. They will be hung on the cavalry's horses at that time, and each person will hang two guns. If you have money, you can hang four guns.

All installed in advance, you can pick it up when you meet the enemy.

And the ignition rate of this thing is higher than that of a flintlock gun, and it is rarely empty.

Everyone understood Ding Yi's needs, and soon a representative Zhou Dahu spoke: "Give us a month first."

Release the blunderbuss in one month, try shooting again, and improve. The fastest is three months, and the slowest is six months.

Ding Yi was overjoyed, but in this way, the progress of flintlock gun manufacturing will drop again.

Fortunately, nowadays, Ding Yi still mainly uses Lumi guns. The output of flintlock guns is low, and he has to rely on low-quality Lumi guns to be sold to Japan and North Korea in exchange for money. It has been a bit difficult to fully equip flintlock guns in the past one or two years.

Two days later, Li Zhongyi brought good news to Ding Yi. After the meeting, they organized craftsmen to observe and study, and one craftsman suggested it.

Modeling, it is said that some parts of this spring wheel gun can be mass-produced by modeling.

This craftsman used to be a printer, and he also did this in Lushun, mainly printing books for Ding Yi's school.

But this time when the craftsman was called for a meeting, he was also called because he was a craftsman.

It was only after he went there that he learned to study how to shoot guns. He wanted to leave, but he stayed and listened. Then they dismantled the wheel gun on the spot.

Everyone was researching with small parts, and the craftsman said that it can be modeled, just like printing a book, one at a time.

Some craftsmen also said that it can be made when the copper is heated and softened.

Everyone chattered and came up with a lot of ideas.

Ding Yi was overjoyed, and quickly explained the principles of modern related hydraulic presses to Li Zhongyi. Of course, he was not talking about making hydraulic presses. The platform is then pressed down. Considering that there is no way to achieve the effect of a hydraulic press in ancient times, it can only be pulled up, then lowered, and heavily forged.

If the copper is heated, it does not need to be pulled too high.

Even, some craftsmen said that you can try it with copper water and directly pour it into the mold to form it.

Ding Yi can only give a general idea. As for how to pull up and then drop the tens of thousands of kilograms of steel, that is the work of the craftsmen.

In theory, this can be used to make armor in the future.

Considering the need for modeling, Li Zhongyi stated that the delivery will be delayed. We need to see whether it is faster to forge or mold filling.

Ding Yi said there is no rush, take your time.

If this step is successful, not only the spring wheel gun, the flintlock gun, but also many parts of the Lumi gun can be accelerated.

The overall speed can be improved.

Not long after, another message came from the Craftsmanship Bureau.

The last time they used fuzed shells in a sea battle, the explosion rate was not high, and some of them would not explode when they hit the sea or encountered sea water.

Now some craftsmen have come up with the idea of ​​blocking the fuze tube with wax after it is ignited, so that even if it falls into the water, there is still a chance to explode.

Some ships are flooded, and if you shoot the second wave of shells into it, it will not explode without wax blocking it. If it is blocked, there is a chance to explode.

The principle is also very simple, the fuze is covered with wax in a thick layer.

After being ignited, the fire will melt the wax, and when it passes through the middle, the lower fuze will ignite, and the upper wax will fall to block the orifice.

The craftsmen tried it, and it was really useful.

Ding Yi was overjoyed again and asked them to make two kinds of shells, one for naval battles and one for land battles without wax.

Because it is used in land warfare, after it is shot out without blowing up, it can be retracted and fired again.

However, in order to prevent explosion when harvesting, water must be poured from the orifice to extinguish the sparks and damp gunpowder inside, so it cannot be blocked with wax.
