In fact, after having Pu nitrate and ammonia, there is basically no need to worry about ammonium nitrate explosives, such as mercury thunderate, nitrocellulose, nitroglycerin, potassium chlorate and the like. The soil method of sulfuric acid, nitric acid and hydrochloric acid is very simple.

What really needs to be worried is the personal safety and the problem of increasing output during the production and manufacturing, as well as the subsequent process improvement and facility and equipment improvement. Of course, in the short term, he would not dare to think of manufacturing a large number of ammunition products. In the early stage, it was mainly ammonium nitrate explosive products, mainly mining and smelting.

As for the processing machinery, the craftsman made and improved many samples according to his design drawings and ideas, which are the most primitive machine tools, molds, all kinds of processing and grinding tools, etc., of course, except for a few hydraulic forging machinery and a few hydraulic drive machine tools, most of them are operated manually. What he does is to constantly expand the thinking of craftsmen and cultivate their ability to innovate in the early stage of design.

At first, Li Chengqian wanted to try a hydroelectric generator, but the copper wire production process and insulation painting process were not up to standard, and the production process of iron core, shell, and roller bearing was also very rough. Soon after the power generation was generated, the coil burned out, and the roller bearings made by the machine tool were also seriously worn, so they had to give up temporarily.

But Hu Liwei, a few skilled craftsmen and stewards, did not think so, and they took Li Chengqian's design plan and principle explanation, and pondered how to improve the craftsmanship all day long, and invited the lacquerware workshop, the woodware workshop, and other interested craftsmen to study together. Dry paint, tung oil, insect wax, shellac, and newly refined coal tar bitumen were all studied. The wisdom of the masses is endless, and it is estimated that it will break through after a while.

Ordinary batteries are now on his agenda, Li Chengqian is not a professional, only understands the principle and the simplest battery production, so he directly explained the principle and use of the battery to a few interested craftsmen several times. Leave the idea and scheme design to these few enthusiasts who can understand it preliminarily, and let them toss.

As for the issue of guns, at present, as long as the quality of the steel is passed, the rest will be easy to handle. Most of the newly made steel is low-carbon steel, some medium-carbon steel, and very few are high-carbon steel. The new steels are processed into roller bearings, springs and tubes, as well as some small atmospheric boilers, and various tests, including strength, wear and fatigue, have been going on for more than a month. A group of craftsmen took the manufacturing principles and technical explanations handed over to them by Li Chengqian, and constantly pondered, constantly changed the processing methods, and constantly experimented and improved.

As for these things like guns and cannons, Li Chengqian wanted to do what he was most familiar with and was best at from the very beginning. The things he was most familiar with and had in his hands on were box guns, 54-style pistols, 56-type rifles, submachine guns, light machine guns, mortars, and the like, most of which were from before the 60s. More advanced weapons, although they have all been seen, and the principles are almost the same, but they have not been exposed to actual production, and he himself is not sure.

However, the ideal is very plump, the design is no problem, but the reality is very cruel, after several experiments, many of the small parts and ammunition of the firearms he designed can only be processed slowly by hand, such as standard parts such as springs, rifled barrels, bullets, etc., there is no advanced machine tool, and the manual can not make a uniform specification and strength of qualified products, and finally the gun plan failed.

When he announced some time ago that the plan would be postponed indefinitely, the craftsman was embarrassed, and after thinking desperately, he got him a souvenir, a large box gun, like a miniature version of a submachine gun, with more than two dozen bullets. In fact, hundreds of bullets were made, but only these 20 or so were qualified, and the pass rate was less than 5 percent.

After a shot, the power is not small, and I am reluctant to use it again. The actual situation is that unless it is a matter of life and death, I really dare not use it again. In fact, he was afraid of exploding, so he gave his life first. There is also the fear that the bolt will suddenly be cut off, blinding his eyes and ruining his face.

After observation and research, review and summary, the key is the forging and casting process, machine tool processing accuracy and ammunition production process problems, to put it bluntly, the current level of technology simply does not meet the requirements, need to constantly familiarize themselves with the improvement process. Later, we had to step back and began to develop incendiary bombs, grenades, mines, breech guns, howitzers, mortars, and other things with relatively simple manufacturing processes.

Although he hadn't done a lot of it, at least he had seen it, and the principle was very simple. Due to the failure to complete Li Chengqian's task in the early stage, the craftsmen are now secretly holding back their strength and want to fight for a breath. Everyone worked hard to learn the knowledge taught to them by Li Chengqian and stepped up the trial production.

Wang Xuance looked at the grenade on the table, remembering that some time ago, the gunpowder workshop was thundering, and the sound of explosions from time to time immediately understood most of it, and immediately thought of the value of this thing. I can't help but have a higher opinion and expectation of this little child.

Li Wujie looked at Li Chengqian's slightly distorted face because of his smugness, hurriedly walked over, filled the two of them with tea, and said with a smile to Wang Xuance: "Lang Jun, you only read the books of sages and sages, and you don't pay attention to these, which is understandable, unlike His Highness, who is fooling around every day and pondering indiscriminately. However, I have often heard His Highness say that everything he does is traced in ancient books. It is just to carry forward the knowledge and skills mentioned in the ancient books. After that, he gave Li Chengqian a blank look.

Li Chengqian was full of interest, and when he saw Li Wujie's white eyes, he couldn't help but be deflated, but as soon as he thought about it, in front of you and in front of outsiders, he couldn't lose his prestige. If you don't pretend today, when will you wait? I didn't have a chance in the future, pretended not to see it, and continued:

"Minghui is right, many things are recorded in books, just like the fire oil that is trying to be refined and processed in the past few days, and it has already been in ancient books.

Ban Gu recorded in his "Hanshu • Geographical Chronicles" that "Gaonu County has water that is combustible]. Fan Ye of the Southern Dynasty wrote the Book of the Later Han Dynasty and the Chronicles of the County in Yanshou County (around Yumen, Gansu Province), quoting the "Naturalist Chronicles" (written by Zhang Hua of the Western Jin Dynasty) as saying: "There are mountains in the south of the county, and there are springs in the stones,...... The ground is a ditch...... It is not edible, and the county people call it stone paint...... Water and fertilizer are also there, and it is not to stop Gaonu County to confuse water.

There is a similar record in the "Notes on the Book of Water" written by Li Daoyuan of the Northern Wei Dynasty. In fact, the thing is the same kind, but the call method is different. What I am doing at the moment is to learn from things, study their characteristics, expand their functions, serve the world, and benefit the world. ”

"Listening to your words is better than reading for ten years. Xuan Ce was truly taught. But what else can this oil do besides ignition? Wang Xuance was completely fooled by these two people this time and couldn't find himself. Dare to love all these things are written in books, why don't you know about it? Alas, reading too few books hurts self-esteem. But oil is not very useful except for making a fire.
