Early the next morning, Wang Xinyu went to the Alchemy Institute first, and spent a whole day teaching Song Yingxing and his son the method of hand-making Dana explosives by laboratory method.

Song Yingxing is worthy of being a famous scientist, and he only remembered the manufacturing method after watching Wang Xinyu operate it twice. At the age of seventy-four, he is even more proficient in operation than his two sons!

"The method of making sulfuric acid and nitric acid, the old man's two dogs have already learned." Song Yingxing stroked his beard and said with a smile.

Wang Xinyu arched his hand to Song Yingxing's father and son: "Old man Song, two big brothers, this place will be handed over to you in the future!" When the day of expelling the Tartars and reviving the Ming Dynasty, you will be the heroes of the Ming Dynasty! ”

"The old man just did a little bit of his best! And what merit is there! Song Yingxing said modestly.

Wang Xinyu turned his head to Li Rui and said, "You go to the king of Yanping and repay the merits of Old Man Song and his two sons." ”

"No!" Li Rui stepped back.

Leaving the alchemy institute, Wang Xinyu took out his pocket watch and glanced at the time, it was only four o'clock in the afternoon, and it was still early, so he hurried to the artillery factory to see the progress of the rifled rifle.

Yesterday at the banquet, Dai Cang talked about this incident, saying that Wang Xinyu's Mini bullet rifle has been completed, and now he and his son are working together to build the barrel of the second rifled gun.

When they arrived at the gate of the artillery factory, the guards at the gate saw Wang Xinyu coming over and hurriedly knelt down on one knee to salute.

Wang Xinyu walked into the artillery factory and saw that the workers inside were busy casting a brand-new cannon. Next to the gun factory, a new water wheel is running, driving the machine tools of the musket factory inside.

Due to the completion of the dam, machine tools and equipment were also transported to Xiamen, and the original blacksmith workshop in Gaoqi was also relocated to the vicinity of the gun factory, and a gun factory was established.

As soon as the forging equipment arrives, it is put into use. Chen Shuijie and Dai Cang also recruited a group of skilled carpenters and blacksmiths to study water conservancy machine tools and prepare to imitate a batch of water conservancy machine tools by themselves. Otherwise, there are not enough water conservancy machine tools now, and we need to use them to build guns, cannons, armor, and spring crossbows.

With a waterwheel, there is a hydro forging equipment, and a lot of effort can be saved by creating a barrel. The red-hot wrought iron plate was forged on a hydraulic forging machine to create a hollow iron pipe, which was then processed by a manpower drilling machine and measured with vernier calipers to drill a uniform caliber, so that a batch of flintlock barrels was produced.

Once you have the barrel, you can assemble a flintlock pistol with various parts such as triggers, springs, and lighters. Because many small parts still have to be built manually, in order to save time to build, some parts are made of copper.

The production of flintlock pistols was not very high, two workers took two days to produce a barrel, and other workers who produced spare parts completed the spare parts of a gun in one day. Due to the limitation of the number of drilling machines, the gun factory could only produce two flintlock pistols a day and 60 a month.

"The monthly output of sixty self-generated fire guns is too low." Wang Xinyu felt very dissatisfied.

Chen Shuijie replied: "General, we don't have enough forging machines and drilling machines. But don't worry, general, we have successfully copied it, and soon we will be able to produce our own machine tools, so that our production will soon be expanded. ”

Wang Xinyu handed over a new drawing: "This is the mortar cannon of the Taixi people, as well as the flowering shells of the mortar cannon, you take it and study it and make these two weapons." The king of Yanping will use it when the time comes. After the cannonball was made, it was handed over to Lord Song in the alchemy room. I'll help out then. ”

"No!" Chen Shuijie saluted.

The output of the cannon factory was okay, and with the technology of iron mold casting cannons, it was possible to manufacture six 24-pound red-coat cannons, 12 1,000-pound Franc machine guns, and 20 Franc machine cannons every month. At the same time, the gun factory can also imitate the British four-pounder copper cannon and three-pounder copper cannon, but due to the shortage of copper raw materials, it cannot produce copper cannons in large quantities.

According to Wang Xinyu's own thoughts, there is no need for the Francophone small cannon to be produced again, the air tightness of the cannon is too poor, the firing range is short, and the rate of fire may not be faster than the British three-pounder copper cannon. However, the king of Yanping had to continue to produce the Franc machine cannon, and Wang Xinyu had no choice but to let the craftsmen continue to produce this kind of chicken-ribbed weapon.

The British three-pounder bronze cannon had a high rate of fire, and its power was much greater than that of the Franc cannon, and it was lighter. There is one point, the cost of copper cannon is high, but it is convenient to cast, and after it is scrapped, it is easy to recast it in the furnace, and the loss of copper in the recasting process is not very serious. However, it is difficult to rebuild the iron cannon to the furnace, and when it is scrapped, it is completely used as scrap iron to re-make iron.

As for the special weapons that Wang Xinyu wants, only Dai Cang's father and son and Claire can make them.

The Thunderbolt short gun used by the special combat team is very good if it can produce one in a month; If you switch the electric gun, you can only produce one piece a month; As for the rocket, the cost of manufacturing the rocket is too high and it cannot be mass-produced.

The rifled rifle that Wang Xinyu desperately needed had not been able to achieve before. With the drilling machine, Dai Cang and his son are making this new weapon. However, the barrel of this gun is too complicated, and none of the eight rifled barrels made before can be used, and all of them have become scrap and can only be recycled.

Wang Xinyu arrived at the gun factory, and Dai Cang's father and son had just made a qualified rifled rifle barrel.

This new type of barrel needs to be tested, forged, drilled several times, and then rifled with a drilling machine. During the test, Dai Cang first poured the granular gunpowder into the barrel, then wrapped the projectile in silk silk, stuffed it into the muzzle, pressed it into it with a strip, and compacted it. Then pick up the primer pot and apply the primer to the pool of the barrel.

The barrel of the gunpowder is tied to a wooden board, the board is placed on the ground, a fuse seven or eight meters long is directed, connected to the barrel of the gun filled with gunpowder and projectiles, connected to the primer position, and then the fuse is lit, and the person leaves, observing the effect.

"Boom" There was a deafening roar, and a puff of white smoke came out from the barrel of the gun tied to the plank.

Several people walked to the wooden target sixty meters away to take a look, and one of Dai Cang's apprentices exclaimed: "What a great power!" ”

The cone-shaped buckshot accurately hit the thick plank sixty meters away, and the plank was an inch thick and easily pierced!

"After my apprentice came, he didn't succeed in building seven or eight barrels, and they all failed. Either the barrel was blown up, or the gas leak was too serious, and those barrels were taken back to the furnace. So our apprentice had never seen the power of this weapon before. Dai Cang explained to Wang Xinyu.

"There's still a little bit of air leakage." Dai Zi walked over to the barrel of the gun on the ground, checked it and said.

Dai Cang said: "Take the barrel to heat it again, and use borax to weld the leakage." ”

Dai Zi disassembled the barrel, took it back and used borax to spot the leaking part, and then put it in the furnace to heat it and weld it.

Wang Xinyu inquired about the process of building this kind of barrel, which was the same as he had detailed on the drawings before: first the wrought iron was beaten into iron sheets, and then bent in the grooves. After that, it is taken to burn red, a steel core is pierced into the middle, and a prototype hollow iron pipe is beaten, and after repeated beating, the inner hole is enlarged with a drilling machine, and then the rifling is pulled out with a drilling machine. In order to ensure quality, the barrel is made of double iron, and it is completely handmade.

It took seven days for the father and son to take two apprentices, two skilled workers and two apprentices, and four people to create a barrel, which is not guaranteed to be a qualified product.

Dai Cang personally took a rifled gun that had been made before and handed it to Wang Xinyu.

Wang Xinyu took it and took a look, only to see that this kind of gun was very finely made, many parts were carefully polished, shiny, the whole gun was very slender, and there was a strip hanging under the barrel. The firing device of the gun is a dog-lock flintlock flintlock machine, which has a high success rate of ignition and exquisite workmanship. Part of the parts of the gun are made of copper, and the butt is also wrapped on both sides, and a layer of copper skin is also wrapped, and all copper products are polished, which looks very delicate and beautiful.

"Every part of this gun is finely made, and it's all made by hand." Wang Xinyu exclaimed.

"Yes!" Dai Cang nodded and said, "General Wang, try this new type of self-generated firebolt!" ”

Someone had already handed over a box of paper-shelled bullets and a pair of sharp-spouted primer pots.

Wang Xinyu took the bullet box, only to find that the box was actually copper! The lid of the cartridge box was opened, and inside lay ten cartridges wrapped in white silk wrapped in cardboard shells.

Wang Xinyu took out a bullet, uncovered the silk cloth on the outside, bit open the bullet case, poured gunpowder through the muzzle, observed the bullet, and found that the bullet was not the original spherical buckshot, but a short conical buckshot, the bullet was pointed, and there were two grooves in the back of the bullet. Wang Xinyu wrapped the bullet in silk cloth, stuffed it into the muzzle, and then pulled out the strip from under the barrel, pressed the bullet into the chamber, and compacted it. Take out the throughbar and put it back under the barrel. Then open the lid of the medicine pool, pick up the sharp-mouthed medicine pot, pour a little medicine into the medicine pool, and then close the lid of the medicine pool.

"Put the target one hundred and fifty paces away." Wang Xinyu said to Gong Xiaoda.

"Can you hit that far?" Although Gong Xiaoda was suspicious, he still did as Wang Xinyu said.

Seeing that the target was up, Wang Xinyu picked up the gun, aimed at the target, and pulled the trigger.

The dog-lock bolt collided violently under the action of the spring, and the flint spewed sparks, igniting the primer. Only a crisp and loud gunshot was heard with a "bang", and a cloud of white smoke erupted from the muzzle.

"Hit!" Gong Xiaoda ran to the target to take a look, and shouted excitedly.

Although it didn't hit the bull's-eye, at such a long distance, the bullet didn't miss the target, which is already very powerful! If it were an ordinary smoothbore gun, it would not be possible at all!

"Let's take a few shots." Wang Xinyu handed the gun to Gong Xiaoda.

Gong Xiaoda first tried firing three shots, and by the time he fired the fourth shot, he had already found his senses. He held his breath, aimed at the target a hundred and fifty meters away, and pulled the trigger.

"Bang" a gunshot rang out, and the high-speed spinning bullet flew out, accurately hitting the bullseye one hundred and fifty meters away!

"Good!" Gong Xiaoda's marksmanship won applause and applause from the audience.

The manufacturing method of this rifle was kept in Wang Xinyu's mind after watching a video of hand-manufacturing a front-loading rifled rifle in his previous life, and after coming here, he drew a drawing. But Wang Xinyu didn't know that the rifle he drew was not a real Miney rifle, but a Kentucky rifle!

Like many netizens, Wang Xinyu regards all front-loading rifled guns as Mini rifles, but in fact, Mini rifles are just a type of front-loading rifled guns, and they are also the last front-loading guns.

The Kentucky long-barreled front-loading rifled gun, a dog-lock flintlock flintlock pistol with a repetition line, does not require a modern industrial base to support like a Mini rifle, and only needs to be built by hand, plus a hand lathe to manufacture. Of course, compared with the Mini rifle with high requirements for basic industry, the biggest disadvantage of the Kentucky rifle is that this kind of gun bullet is not a sub-caliber bullet, it is difficult to load, and it needs to be loaded with a silk wrap bullet, and a skilled gunner can only load one round a minute at the fastest speed.

In fact, at the level of technology of those years, without a steam engine and without stamping equipment, it was simply impossible to achieve a real mini-rifle. First of all, the Minny rifle has very strict requirements for accuracy, the bullet must be less than 0.2 mm of the barrel, and a deviation will lead to the accuracy being inferior to the smoothbore gun! In this way, the accuracy of the bullet is very high, and the manufacture of the bullet is much more difficult; Secondly, because of the expansion effect of the bullet skirt of the Mini rifle, the rifling wear is extremely serious, and the requirements for the barrel are very high, and it is difficult to create it by manual methods, even if it can be manufactured, the construction period will be too long, and the cost of the gun will be ridiculously high.

The production of real mini-rifles requires basic industry to support. When the basic industry of mankind developed to the point where it was possible to manufacture mini-loading rifles, breech-loading rifles were already available, and for this reason, mini-loading rifles only existed for a short period of more than ten years before being replaced by more advanced breech-loading rifles.

The Kentucky rifle, on the other hand, has very low requirements for basic industry and can be manufactured by hand, requiring only a set of blacksmith shop equipment, plus a manual drilling machine and measuring equipment, to make this primitive long-barreled front-loading rifled rifle.

But as a rifled rifle, the Kentucky rifle has an effective range of up to an astonishing 400 meters, and its accuracy is extremely high, making it particularly suitable for use as a sniper rifle. As a sniper, it doesn't matter how fast or slow you reload.

Kentucky rifles, in real history, during the American Revolutionary War, on October 7, 1777, the American sniper Murphy killed the British general Simon Fraser at a distance of 500 yards, or about 450 meters.

Wang Xinyu didn't know about the Kentucky rifle and took this gun for a mini rifle. However, he did not use the name of the Mini rifle, but called it a sniper rifle.

However, the production of this kind of gun was extremely costly and costly, and directly tied up three outstanding talents including Dai Cang, Dai Zi, father and son, and watchmaker Claire. And this gun is complex to operate, and only the best shooters can use it. Wang Xinyu expects to produce one to two pieces a month, equipped with monoculars, to equip elite sharpshooters, specifically for shooting enemy commanders.
