Liu Jun asked Zhao Shun, "What materials are still missing in the workshop?" ”

"The most lacking thing now is craftsmen." Zhao Shun was very grateful to Liu Jun for giving him a new life, so he didn't mean to be fooled at all, "To make a firecracker, you need skilled blacksmiths, coppersmiths, and carpenters, and you are not ordinary craftsmen, you have to be skilled firecracker craftsmen." ”

Liu Jun glanced at a group of people in the workshop, these were craftsmen who knew how to do their craft, and they were selected by him to establish this workshop with Zhao Shun. "If these people are right in front of you, how many bird guns can you make in a month?"

Zhao Shun looked at the surrounding people with some embarrassment, and said with a wry smile, "If it's just us, we can create a good bird gun in two months." ”

"What?" Liu Jun was shocked. There are more than a dozen craftsmen here, and it takes you two months to make a bird's gun? Isn't it a dream that the workshop he expects to produce and make the nine-headed bird self-sufficient?

"It's quite complicated to make, and it's a hassle to say." Zhao Shundao.

"Tell me carefully what is affecting the speed of production." Liu Jun really hopes that he can build a firearms workshop that can supply the surplus of the nine-headed bird. But if a dozen people can build one in two months, it's. Although he doesn't know much about the process of making firebolts, he may be able to offer some advice. At the very least, it can solve some needs.

Zhao Shun, a big man in Shandong, immediately came to the spirit when he talked about the method of making firearms.

"To make firearms, you first need Fujian pig iron, and Fujian iron is the most suitable for making firearms. With ten catties of Fujian pig iron, one catty of refined iron can be refined, and then it can be used to make firecrackers. ”

Of course, refining the fine iron suitable for the manufacture of gun tubes is only the simplest step.

Liu Jun said directly, "Now that we have few people, let's directly buy high-grade fine iron, which should save some time." ”

Zhao Shun nodded, but this could only save a little time.

As far as building the most equipped bird gun today, after the fine iron is prepared, there are still four major processes. The first major process is pipe making.

"My lord, Song Yingxing, a native of Jiangxi, published and printed in the book "Heavenly Creations" published in Chongzhen ten years, has a special sermon on how to make bird guns, which writes that where the hammer bird is hammered, the first iron is as big as a chopstick, and the cold bone is wrapped in a red iron hammer. The first is three connections, the interface is red, and it is trying its best to collide. After the combination, the quadrangular steel cone is used as a big one, and it is rotated through it to make the aurora clean, and there is no blockage in the medicine. This is a manufacturing process that has been used for many years. ”

"In general, the process of making bird guns is complex and requires highly skilled craftsmen."

"The traditional production process is to use a three-stage jointing type, which is the one that Song Yingxing Tiangong Kaiwu said, and the method is to make the gun pipe first, and the gun pipe is made of refined wrought iron section by section, generally two or three sections, and finally into one."

"In this process, we first prepare a round steel stamen about one foot long to make cold bones, first burn the wrought iron to make the pipe until it is red-hot, then take out the blank that has been burned to a certain temperature, and use a hammer to knock the hot wrought iron outside the steel stamen and roll it into an iron pipe. Then, in the process of cladding iron, the steel stamen is continuously extracted and cooled with water to prevent the steel stamen and wrought iron from being welded together. The thickness of the rolled iron pipe should also be at least three minutes thick, so that the pipe can be strong and withstand more than ten consecutive launches. ”

Liu Jun nodded, Zhao Shun said very straightforwardly, he heard it very clearly.

"The second step is welding. Because the long guns of more than three feet are welded together in sections. Therefore, this step of welding is very reused, and it is easy to blow up and bored the gun that is not well connected, and whether the gun tube can be connected is the most critical part of the success or failure of the gun making. In the past, because the craftsmen of the government were not strictly supervised, they often cut corners and cut corners when manufacturing, causing many accidents. Therefore, for a good bird gun, welding is of the utmost importance, and the most experienced craftsman is required. ”

Liu Jun hurriedly picked up the pen and recorded it.

"It is very important to have a good skilled craftsman put the iron pipe that had been made in the furnace and burn it to the ashes, and also to prepare a steel stamen, the same thickness as above, and the length of the gun. Then the iron pipe that has been burned to red and bright is set on the steel stamen, and the iron pipe interface is smashed into one by the master craftsman, and at the same time of welding the iron pipe, special attention should be paid to sprinkling white copper powder at the welding mouth of the iron pipe, because the white copper powder can make the interface stronger and will not leave a fault or falsehood. The steel stamen should also remember to extract and cool it at any time, and the cooled steel stamen will be heated with the iron pipe at the same time, and the final iron pipe will be regarded as the prototype of the gun pipe. ”

Liu Jun looked at the process steps he had written down, and couldn't help nodding, "It's really complicated, isn't there a simpler process?" ”

"Yes." Zhao Shun's answer surprised Liu Jun a little.

Zhao Shun said proudly, "My father once passed on to me a new craft of making guns, which was passed down from Mr. Zhao. I was talking about the traditional technique of making guns, also known as the three-stage jointing type, but what my father passed on to me was the double-layer composite type. ”

"Double-layered?"

"Yes, in fact, the double-layer composite type is contained in Qi Shaobao's new book of Ji Xiao's siblings. This two-phase package is actually a double-layer composite type.

"Is the double-layer composite more advanced and convenient?" Liu Jun listened to the three-stage joint just now, and felt that it was too complicated.

"Well, the double-layer composite type is completely different from the three-stage joint type, the double-layer composite pipe making method is directly wrapped with red iron on a steel stamen more than three feet long, and when the first layer of iron is wrapped, another layer is wrapped on this layer of gun, so that the joint of the inner gun is wrapped by the outer layer of gunned body to form a composite body."

"The joint of the gun body created by this method is stronger, but this type of gun tube cannot make a very long gun tube, but the gun mouth can be made larger than the first type of gun tube, so the power is also greater at the effective distance. The people of Dongying call this kind of large-caliber short-bodied bird gun an iron cannon, but now many craftsmen in our dynasty still generally believe that the longer the bird gun, the more powerful it is, such as the spear in the adult team, which is actually developed and manufactured under this concept. ”

"Is this verified?" Liu Jun doesn't care what these craftsmen argue, what he needs is results.

Of course, Mr. Zhao has personally verified this. Both the Lumi Gun and the Switched Gun are made using a double-layer composite method. ”

"Then we'll use a double-layer composite type." Liu Jun made a decision.

However, Liu Jun was still happy too early, although the two processes of pipe making and welding are extremely complicated, but this is not the most time-consuming process.

The most time-consuming process in the manufacturing process of bird guns is actually trimming.

At the beginning, the bird guns were all octagonal, with one thick end and one thin end, the thick one made the belly, and the thin one made the mouth. The crosshairs are welded in the same way after the gun body is welded. The crosshair and the illumination are just two protrusions before they are processed and have no effect.

The fire table is drilled in advance on the gun body and the fire table before welding, and it should be welded on the position of the fire transmission hole and not blocked.

At this time, the bird gun can only be regarded as a rough embryo, and it needs to be drilled out of the barrel again to frustrate the crosshair.

However, the level of technology at this time is limited, the section of the steel is neither pure and round, the body is not straight, the boring is rough and uneven, and the boring is also drilled with a drill bit.

In the beginning, it was just a manual drill, and later there was a drilling machine.

According to Zhao Shun's introduction, this kind of drilling machine is made of wood as a frame, and the round stone disc is used as an inertia wheel, which is pulled by manpower after tying a leather strip, so that the stone disc drives the drill bit to rotate. The drill bit and the frustration knife are made of hard steel, but the bore has to be scraped after the bore. It is also recorded in the new book of Ji Xiao, the original hole of the bird gun is very small, drilled with a steel drill, scraped an inch a day, until the end, and the drill is light in January.

After drilling a gun pipe in a month, it is still fast, which shows how time-consuming this process is.

The most important thing that restricts the production time of the firearm is the process of drilling and scraping. A drilling machine can only drill one pipe in a month.

Liu Jun thought for a while, "How about getting more drilling machines, one drill a month for a gun bed, then we can get a hundred drill machines, at least one hundred can be drilled in a month, right, if you get a thousand, it will be a thousand a month." ”

Zhao Shun was stunned, he didn't expect Liu Jun to be so domineering, a hundred drilling machines and a thousand drilling machines, he didn't dare to think about the scene of so many drilling machines lined up to drill guns.

"It's not enough to have a drilling machine, you have to have a craftsman."

"If there are not enough craftsmen, we can recruit them and teach them ourselves."

"That's a lot of money." Zhao Shun wiped his sweat and reminded.

"Anything that can be solved with money is not a problem." Liu Jun waved his hand and said domineeringly. "What's next?"

"After the bore is drilled, the inside of the bore is scraped clean with a four-edged steel bar, so that the bore is completed. The next thing to do is the back door of the firebolt, that is, the plug at the end of the gun, also known as the screw turn, "Ji Xiao Xinshu" has a record: silk turn, left turn in, right turn out. The belly is long, such as lead or fire door, etc., take the door wire after opening it to make it easy to trim. ”

This is one of the finest parts of the firebolt, second only to the crosshair and plate mechanism.

By this time, the fire gun has been roughly completed, and the last step is the mechanism and assembly.

Under Zhao Shun's careful introduction, Liu Jun learned that the plate machine and faucet of the bird gun are a complete set of mechanisms, which must be manufactured by coppersmiths, and the plate machine, faucet, cover, and fire door cover are all made of copper materials, while the springs are made of steel.

After the pipes and mechanisms are manufactured, the final thing is the connection between the pipes and the bed. The bed is made of carpenters, and the wood is made of tough and less water absorption, and does not deform or crack after drying, and is fixed by two sections of copper hoops. Although there will be some inconvenience in cleaning, it can speed up the production and manufacturing time, and there are gains and losses.

"A handful of birds, blacksmiths, charcoal, copper, wood, and craftsmen's food and food, the total cost is three to five taels of silver."

"It's not too expensive, but it's too long." Liu Jun sighed.

After thinking about it, Liu Jun said to Zhao Shun, "If the various manufacturing processes are separated, and different processes are manufactured by different craftsmen, such as welding, the most important processes are manufactured by the most skilled old craftsmen, and some processes such as drilling, scraping, and knocking pipes are taken over by some craftsmen with slightly less experience, do you think it's okay?" ”

Liu Jun is talking about the assembly line operation method, which breaks down all the manufacturing processes of the bird, so that those skilled craftsmen are only responsible for the most important processes, and some of the simpler processes are handed over to some less experienced craftsmen, or even some apprentices. In this way, the demand for skilled craftsmen, especially those who are advanced, will be reduced, and the quality of production will not be reduced by having these skilled craftsmen take care of the core processes.

Of course, the most important thing is to increase the speed of production.

"That's fine, but I'm afraid that in this case, the quality will not be guaranteed." Zhao Shun said worriedly, a bird gun handles more than a dozen dozens of people, which is definitely not as good as the original old craftsman personally checked and manufactured.

Liu Jun smiled, "You don't have to worry about this, I have a way, each part must be engraved on the person who made it, and then it must be registered, and each piece of Cheng Gong must also be marked with a serial number and entered into the book one by one." In the end, when the bird gun is used, if there is a problem, the craftsman will be found in the end and held accountable. Good quality is certainly rewarded, but if the quality is low, it must be held accountable at that time. Of course, we also have to set up quality inspection, check the quality of each process, and refuse to enter the next process if it is not up to quality. There must be both inspection and general inspection, in short, the quality must be strictly controlled. ”

Zhao Shun was surprised by Liu Jun's endless ideas, but he did feel that these methods were very effective.

"In this way, we immediately went to various places to recruit craftsmen, and also sent people to purchase the drilling machines, drill knives and other tools we needed, and we purchased 100 units first, and copper and iron were also directly purchased." Liu Jun decided to make his own firearms, and he also made a bloody investment.
