Chapter 194
There is nothing fancy about artillery. To fire a hundred rounds without blowing up a simple cast iron two-pound gun, the barrel must weigh more than two hundred catties. A small one-inch-caliber gun with a two-pound-heavy wall was considered inappropriate by Lao Guan, so he simply didn't build it.

The copper cannon is light, with a caliber of one inch, a muzzle of two inches, a tail of three and a half inches, and a length of three feet and four. Get up, and then play it before it explodes, which can avoid danger.

It is expensive, a two-jin cannon counts the waste, and the material cost is 13 taels of silver.

It’s okay to use this for infantry guns. There’s no need to use such expensive things for ship guns. The cost of more than 200 catties of iron guns is only four taels, and it’s more suitable. The biggest problem is that the iron guns are not big enough to be made into big mules. Do not move.

Laoguan also has another cannon for Chen Mu to check and accept. It is a cannon with iron core and copper shell, which is thicker than copper cannon and more durable than iron cannon. The clay mold needs to be made twice, once for the iron core and once for the copper shell.

The new cannon is lighter, and the shells it fires are also less powerful. It can hit 270 paces, and the shells spread very badly beyond 270 paces, and are completely inaccurate beyond [-] paces.But its lightweight characteristics can also shine in the ensuing road wars.

A new type of gun carriage was also made. The gun carriage pulled by a horse has two wheels. The extended anti-crank iron gun carriage can fall to the ground when placed, which can help the artillery to remove the recoil force and Equipped with a handle for light gun screw adjustment, it is extremely easy to use.

Including a full set of cannon body and cleaning tools, 250 packaged shells and gunpowder, the copper cannon weighs [-] jin, and the iron-core copper-cased cannon weighs [-] jin and a half. The shells are ten solid iron bullets and two new-style shotguns .

At the same time, due to Chen Mu's request, in order to deal with the worst road conditions or the dilemma of mules and horses being exhausted, there are several detachable parts on the gun mount that only slightly affect the stability. In the worst case, it can be driven by life.

After all, there are too many mountains and rivers in the south, and Chen Mu doesn't know if there are any road conditions that allow him to transport troops calmly when the war is approaching.

Artillery is power, and his army must have artillery support in time of war.

If every general banner bearer had one two-pound cannon, and a thousand households had five five-pound cannons, the enemy would be defeated in a round of three hundred paces away.

What surprised Chen Mu was that Guan Yuangu's cannon had already been forged. He thought that for every inch of caliber, the length of the cannon would be three feet and three inches, so that the shells could be fired in a straight line as much as possible. This made him very gratified.

The co-authored new gun is still a 33 times caliber gun. This measurement method is relatively simple, because Laoguan calculates the length of the whole gun, including both the medicine room and the breech.

Generally speaking, it is a pioneering work, and it can be pushed to customize artillery in the future. In turn, the length of the gun body of the ten-jin cannon can be calculated, which will reach one foot—Chen Mu feels that when his ship cannon is built, there will be no red in this land. What happened to Yi Pao.

"Wei Balang's child soldiers will be stationed in the artillery factory in the future. No one is allowed to enter or leave when they have nothing to do. Anyone who violates the law will be killed on the spot." When leaving the artillery factory, Chen Mu issued such an order, "Use clay molds to test the cannon and try it out. For customizing, you can use an iron mold to separate the iron mold with mortise and tenon, brush the material that can separate the molten copper and iron, pour molten iron, and then hang it to another iron mold to pour copper water, saving the mud mold from breaking Do it again, it will be much faster.”

"As for what is suitable for brushing and how to do it, I don't know much about it. I have to rely on Carpenter Guan to try it out, as well as the temperature of the furnace." Chen Mu tapped his head and said, "I'll go back and think of something that blows the wind. It’s better to slow down the temperature of the cannon, so Guan Jiang should pay more attention.”

Guan Yuangu took a few craftsmen to send Chen Mu all the way outside, watched Chen Qianhu get off his horse and got off again, and asked, "Guan Jiang will find a pen official and compile the process of making guns into a book, so that it can be handed down to the world in the future." of."

On the way back to the Yamen, Chen Mu has been feeling deeply about this era. In fact, there is nothing magical about training soldiers. There is nothing special about a brand-new thousand households gradually developing into a thousand households that can fight wars and have elite soldiers. What really made him feel emotional was the Xiangshan Army Equipment Bureau and Xiangshan Shipyard.

This is truly starting from scratch. Guan Yuangu made the first blunderbuss, and Guan Laoer made the first breech bed. Originally, it was said that Guan Zun'er would go to the Nanjing Ministry of Industry to take a small job, but now in a blink of an eye With the Arms Bureau, there is no need to go out to work.

The development of the Arms Bureau is really fast. It only needs technology and skilled craftsmen, and Guangdong can provide everything else.Compared with the output of Foshan, the largest iron smelting distribution center in the south, the iron materials consumed by Xiangshan Military Bureau are just a drop in the bucket.

As soon as he returned to the yamen, Shao Tingda, a thousand households in Shunde, sat on the threshold of the yamen with a depressed face, and a few flag soldiers of the Qianhu Shunde stood timidly beside him, begging for water with the soldiers guarding the yamen.

"Brother, you are back."

"Hey, isn't this Shao Qianhu!" Chen Mu smiled and walked around the bewildered Shao Tingda twice, and finally patted him on the shoulder and asked, "Isn't it beautiful to be a thousand households?"

Throwing the reins and letting the soldiers lead the horses to the stables, Chen Mu took Shao Tingda and walked towards the yamen and said: "Go in and sit, even if you go to Shunde, you are also my brother, why sit outside, and your soldiers, go into the yamen to rest, Zhengyan is going to ask someone to order some food and wine, treat him well."

Sitting in the main hall, the smile on Chen Mu's face still couldn't go away. No one in the Xiangshan Qianhu Office thought that Shao Tingda would be the first to become a thousand households. Based on their military exploits, the first ten hundred households were promoted to deputy thousand. It makes sense that the three hundred households in Haojing would be able to be promoted to official positions like Qianshi in Zhusuo at most.

"Brother Mu, are you ready?"

Chen Mu's splint was gone, he looked down, stretched his arms and said with a smile: "It's not finished yet, it will be soon—let's talk about what Shunde needs."

"Sigh, being a thousand households is not comfortable at all." Shao Tingda sighed long and hard, "Shunde Qianhu needs no money, no food, no food, only after I went there did I know how difficult it was for you when you first came to Xiangshan, and I also Without your ability, I can only find Brother Mu to rescue the soldiers."

As he said that, Shao Tingda pointed to the outside with a bitter face, and said, "Look at the ragged clothes of my Banner Army, this is already the most capable soldier in the camp. There are more than 400 people in the camp. Some old Banner Army soldiers think that I Thousands of them were killed, and they refused to accept it, and those new banner troops couldn't fight, so they couldn't handle anything."

"I want to borrow money, food, or people, Brother Mu help me."

Only Chen Mu can help with these things, and only Chen Mu is willing to help, he said with a smile: "Recruit soldiers first, you will stay in Xiangshan for a few days, and learn how the army weaves, Lao Bai and the others are also learning, wait The rewards will definitely be given out to be the deputy thousand households, I don’t know how the Ministry of War will arrange for Chen, if there is no accident, the silk weaved and the timber cut will be transported to Xiangshan, once a year.”

"The silver is divided into the military households, the storehouse and the future guard storehouse. All the guards in the storehouse can only get two points. At least let the flag army eat and wear warm, and the rest will go into the storehouse. In the future, the Xiangshan Armament Bureau and the shipyard will clearly mark the warships and ships. The price is marked, and it is supplied to every thousand households."

Chen Mu's words didn't sound like much at first glance. In fact, he wanted the guards to form a complete industrial chain and self-contained system from the supply of raw materials, the realization of materials to the return of output.

"Now the two offices are different from each other, and the treasury cannot be moved. I will pay you a thousand taels of silver from the private treasury, and transfer a hundred-household office from Xiangshan to help you recruit and train soldiers. The other things will be discussed after the imperial court rewards you."

　For the weight of the copper cannon, it is known that the height of the cylinder is 105cm and the radius is 4.7cm, so its volume is 7286.77 cubic centimeters.

　　It is known that the specific gravity of copper is 8.9g per cubic centimeter, and 594.6g per catty in Ming Dynasty, so the weight of the copper column is 109 Ming Jin.

　　The known caliber is 3.4 centimeters, calculated according to the bore of 85 cn, the same formula can be drilled out of the bore of 11.5 jin.

　　Under absolutely ideal conditions, the gun weighs 97.5 Mingjin.

　　The actual gunmetal is a tin-zinc-copper alloy, and tin-zinc is lighter in weight, maybe five catties lighter.
