The end of the Ming Dynasty swept the world

Chapter 368 Epoch-making Products
At the end of November, Ding Yi came to Pig Island to work as a craftsman.

Zhou Dahu and his wife Zhao invited him to come. The Craftsmanship Bureau is the place where Ding Yi visits the most and he visits many times every year, but this is the first time that Zhou Dahu and his wife Zhao invited him here. Ding Yi is very happy .

Sure enough, when they came to the scene, they found that there was an extra machine here.

"Wow..." Ding Yi could not help squatting down as if he saw a beautiful woman, and stroked her gently.

This is a machine that Zhou Dahu and Mr. Zhao spent nearly a year building. They call it 'broaching machine'.

The broaching machine is made of steel and clam wood, using the gears drawn by Ding Yi more than a year ago, with more than a dozen gears of different sizes on it.

It took them half a year to make these gears alone. The water wheel can be connected to the right side, and the power of the water wheel can be used to pull the gears, and then the power of the gears can be used to pull the gears to form a spring.

Zhou Dahu cheerfully gave Ding Yi a bunch of newly made springs.

This is practiced three more times with Su Steel to maintain the proper toughness and strength. After polishing, it is pulled into a spring with a broaching machine. The strength is very strong, at least the best spring in this era.

Mrs. Zhao said that the spring problem has been solved by almost [-]% at present, and now it is mainly because the standard of the steel wire before the spring is made is difficult to be exactly the same.

They are all polished by craftsmen, and the standards will have errors, and it will take time.

Ding Yi asked them to take a look at the grinding site, and found that their process was like this. First practice Su Gang for the second time, and when the fire was fired for the third time, he pulled it out and hammered it at the same time, which is called high-temperature processing. It is very thin and narrow, and it can probably be drawn to the thickness of a ballpoint pen refill in later generations. This is the limit thickness, and if it is pulled further, it will break.

After cooling in water, the workers began to polish, and this step involved the largest amount of work.

So there will be errors in this step and it will take time.

A one-meter-long steel wire needs to be polished by one person for a day, and only a dozen or so finished springs can be pulled out. About half of them will affect the elasticity due to errors.

After Ding Yi saw it, he thought for a while: "Let's go, I'll take you to a place."

The craftsmen were baffled, but they still followed Ding Yi to another place.

This is where the guns are made.

In ancient times, long spears were made of thick wood, oak wood, locust wood, etc., and bamboo, tendon wood, ash tree, Kundian wood, etc. were used in different places and times. In the Ming Dynasty, Qi Jiguang said that the best way to make long spears Use thick wood.

Most of these woods are found in the south and the tropics, and some are relatively expensive. Ding Yi's south Liaoning side grows locust wood, which is also his main material for making long spears.

The craftsmen were quickly taken by Ding Yi to the place where gun barrels were made.

The carpenter fixes the two ends of an irregular piece of pagoda wood that has just been cut open and is as thick as an arm, and then starts to turn it.

Someone took a finger-thick shovel and put it on the pagoda tree. Swish, swish, sawdust rolled down like rain. After a while, the irregular pagoda tree just turned into a smooth gun shaft.

Zhou Dahu and other craftsmen of gunsmiths understood it in an instant.

"Wonderful, if the steel wire is processed in this way, the specifications will be exactly the same, and there will be no error."

Polished by hand, it is better to polish like this.

But the steel wire is very thin and metal, so the tool like a spatula needs to be carefully considered by the craftsmen, so that it can process the steel wire without cutting it.

Ding Yi meant that because the steel wire is easy to break, it can be processed in small pieces.

Calculate the length required to make a spring, so that it is not easy to cut off. After processing, it can be directly pulled into a spring.

Zhou Dahu and others nodded one after another.

Mrs. Zhao suddenly said: "If the steel knife is hard enough, can we also process the gun barrel in the same way, and it will be much faster?"

They were the first to process gun barrels, which were made into steel sheets and wrapped around iron rods to form a round shape.

Later, there was a drilling machine, which was made into a square iron rod, then drilled holes, and then polished into a circle.

Today I saw the way a carpenter makes a spear, and I immediately felt that I could learn it, and the gun barrel can also do the same.

"En." Ding Yi thought about it, of course it is theoretically possible: "This is called a lathe, but the turning tool is not easy to make a steel car into a circle."

"We must study on this." Zhou Dahu said: "Master Ding said this turning knife, try it a few more times, it is all made of fine steel, and it needs to be hard but not brittle. If it is made, it will be fine. The time for making guns can be at least several times faster."

Of course Ding Yi knew it, but he didn't know what material the turning tool was made of in his previous life. However, when the turning tool was processed, the temperature was extremely high, and ordinary steel probably wouldn't work. In this era, it is difficult to have such a skill.

But Zhou Dahu is willing to research in this direction, he is very happy.

"Yes, you can think about it, if you can succeed, you will definitely be rewarded."

Mrs. Zhao covered her mouth and smiled softly, "My Xin'er, he wants to be the study committee member in the class, can you accommodate me?"

Everyone around is in a hurry.

Ding Yi disturbed his head in embarrassment: "You can't openly ask the official to open the back door like this."

Zhao suddenly pursed her mouth.

"However, I'm sure. It's a good thing to want to be an official at such a young age. Hahaha." Ding Yi laughed.

All around immediately burst into laughter, and Mrs. Zhao also smiled.

"You bitch, how could you openly ask for an official?" Zhou Dahu murmured, the request was also private.

Soon Ding Yi returned to Zhou Dahu's workshop and saw the new flintlock.

This spear is four feet five in length, a bit shorter than the Lumi blunderbuss, but the barrel of the blunderbuss is made of fine steel, and it can fire thirty rounds in a row before deforming.

If you don't fight continuously, you can hit more than 60 guns. They have tried to hit more than [-] guns, and there has been no change until now.

After using the new spring, the ignition success rate reached more than [-]%.If you hit ten guns, you can hit seven or eight guns, and sometimes with luck, you can hit nine guns. This success rate is very high.

The key is that the difference between him and the Lumi gun is that the Lumi gun did not fire for the first time, which is more troublesome. It takes at least a few seconds, or even more than ten seconds to fire the second time.

The flintlock didn't fire for the first time, but with a little adjustment, it could be fired again in two or three seconds, or even within one second after being proficient.

This gun is definitely an epoch-making product. Ding Yi feels like a handicraft when holding it in his hand. The barrel is all stainless steel, and the handle is made of clam wood. Can continue to use.

The total weight is eight catties and two taels.

The maximum range is about 200 meters, and the limited damage is best at 100 meters to 150 meters. It is very easy to break heavy armor within 120 meters.

In fact, the range of the flintlock is not much longer than that of the Lumi gun, but the armor-piercing range is one-fifth higher. Another advantage is that it can be used in rainy days, and the speed is faster. A well-trained shooter can shoot every minute Hitting two or three rounds is not a problem.

This is the most powerful weapon of this era.

At the same time, Europe also had flintlock guns, but Ding Yi's style and performance technical level have surpassed those of Europe.

It was not until the middle of the 17th century that Europe recognized and equipped flintlock guns on a large scale.

The flintlock had many advantages, but it also had serious disadvantages.

First of all, it is expensive and uses more steel. In fact, the manufacturing process is complicated, especially the flintlock guns on Ding Yi's side.

The gun body is made of fine steel, and it needs to be tempered several times with Suzhou steel. It will consume a lot of steel, labor, and time in the early stage, not to mention the production of small parts such as springs.

According to Zhou Dahu and his wife, the cost price of such a flintlock gun (Ding Yi's labor is not counted, only material consumption) is 12 taels, twice that of the Lumi gun.

If you give up Lumi guns and focus on making flintlock guns, you can only produce [-] barrels per month.
