After finishing the work of recruiting soldiers, Li Zhi began to make boring machines. Pen, fun, and www.biquge.info

A boring machine is a machine tool used to process the holes of a perforated workpiece, which appeared as early as the fifteenth century and is used to process artillery. The more mature boring machine in modern times was invented by the Englishman Wilkinson in 1774, which was originally used to process gun barrels, and later improved to process steam engine cylinders.

As an industrial designer, Li Zhi certainly knows the principle of boring machines.

Li Zhi has now made the bearing, and it is a matter of course to make a boring machine. Li Zhi made a manpower boring machine. After casting a few gears for the transmission, Li Zhi transferred the rotational force of the human rotation to the boring bar. The boring bar rotating in the bearing is very stable, and the boring bar gradually moves forward during high-speed rotation, which gradually expands the hole of the workpiece.

Using a boring machine to process holes in the workpiece is much more accurate than drilling with a drill bit, and can be used to drill holes with higher accuracy.

The boring machine made by Li Zhi is used to process rifle barrels, and the boring rod Li Zhi uses the best steel he can collect - Susteel. Although there is no alloy steel, there is no problem in cutting wrought iron from Suzhou steel after quenching and tempering.

Li Zhi took ten blacksmiths to work in the blacksmith shop for fifteen days and made the first boring machine of the Ming Dynasty.

After the boring machine was done, Li Zhi made a special fixing groove for the barrel on the boring machine, so that the gunsmith could use the boring machine to bore the barrel. The gunsmiths first used a thin boring bar and then a thick boring bar, and it took a day to bore a barrel.

The barrel was bored out, and it looked good, but Li Zhi didn't know the bottom in his heart. He asked the gunsmith to inspect the boring barrel with four times the usual amount of gunpowder, and found that there was no crack in the barrel after the gunpowder was exploded, and there was no problem.

After the experiment was successful, the gunsmiths looked around the boring machine and were amazed at the ingenuity of the machine. The general must be the reincarnation of Lu Ban, otherwise how could he invent a new thing every once in a while?

Follow the general to do things, and the future is bright.

"Your Excellency is clever!"

"My lord is really a fairy-like figure!"

"I've been making bird guns for ten years, and I don't know I can do this with a barrel!"

Hearing the admiration of the craftsmen, Li Zhi smiled proudly.

With this boring machine, the manufacturing speed of the Mini rifle can be greatly increased. Now the barrel can be bored in a day, and it only takes seven days for a gunsmith to complete the entire process of producing a Mini rifle. Compared to the previous speed of making a rifle in a month, the boring machine can make it three times faster.

In the past, there was no boring machine, so Li Zhi had to hire more craftsmen to make rifles. In fact, Li Zhi has already collected all the gunsmiths in several surrounding states and counties, and hired more gunsmiths to go to the capital or Shandong, which is very unsatisfactory in terms of operation and cost. But with a boring machine, the barrel can be processed much faster, and Li Zhi does not need to continue to expand his team of gunsmiths.

After making the boring machine, Li Zhi seemed to have seen tens of thousands of Mini rifles piled up in the warehouse.

With more rifles, soldiers will be able to organize more target training and not be afraid of shooting too many scrapped guns. Because of the regular target training, the four thousand veterans are now nearing the end of their service life and need to be equipped with new guns. Coupled with the fact that four thousand recruits require a lot of target training, the number of guns required for training is very large.

The scrapped firearm materials can be disassembled for recycling, and each part of the gun can be recast separately, which means that the scrapped firearm is remanufactured without much material cost, only labor cost. The boring machine greatly reduces the labor cost of making guns. So it doesn't take much silver to scrap and rebuild guns.

Li Zhi immediately asked all 500 craftsmen to stop making Mini rifles, and all of them organized to make boring machines, and they wanted to build 100 boring machines within a month. With 100 boring machines, and 500 craftsmen taking turns using them, more than 2,000 Mini rifles can be produced in a month, which can meet the training needs of 8,000 soldiers.

In mid-November, the temperature was already very low, and the cold wind was howling. The mud nests in the north of the city are no longer able to help the refugees withstand the bitter cold, and the wind is leaking everywhere. Fortunately, the houses for the refugees have already been built -- Li Zhi recruited 1,500 masons from the surrounding prefectures and counties in September, and the refugees have done their own work for the masons themselves, so that the new houses of more than 2,000 refugee families have been built by mid-November.

The refugee's house has a tiled roof, which is protected from rain and wind, but the bricks of the house are not plastered with lime in order to meet the deadline. The cement brick walls are bare, and they don't look so beautiful. However, the refugees are not so particular, and they used to live in leaky thatched-roof mud houses in their hometowns, and they are very happy to live in brick houses.

In the future, when the refugees have harvested food and lived a prosperous life, it will not be too late to find someone to paint white lime.

Not only that, but the houses built for the refugees were also relatively small, with 1,500 masons building 3,200 rooms, which would mean that three refugees would share a room. But this is not a big problem: the houses built for the poor are clustered in small villages, leaving a lot of room between houses. When the first year has passed, and when the poor have harvested food and silver in the second year, they can expand their houses on the reserved space.

In addition, the refugees did not have enough quilts and clothing.

Although the refugees also carried cotton clothes and quilts when they were plundered by the Tartars, this is the only valuable thing for the poor families, even if they were plundered by the Tartars to Liaodong, they would also carry cotton clothes and quilts. But judging from the standards of Fanjiazhuang, the cotton clothes and quilts of these poor people in the Ming Dynasty are very cold - tattered cotton clothes, quilts shared by several people. Relying on such equipment to survive the winter, it is inevitable to suffer from freezing.

Li Zhi didn't want someone in his territory to freeze to death, so in October, he asked people to go to the surrounding states and counties to buy 6,000 quilts, and ordered 6,000 sets of standard cotton jackets worn by Fanjiazhuang soldiers, and the cotton jackets were dyed with the big words Fanjiazhuang. These things were in place by mid-November. Li Zhi sent them to the poor people's villages and distributed them to the poor people.

These padded jackets were wide, and the poor people could put them on if they could. Of course, Li Zhi also gave needlework scissors to the poor - if the size of the padded jacket was too different, he would change the size by himself. Women in the Ming Dynasty were all able to do needlework, and they were able to change their clothes.

When the peasants heard that the Shogun had given them winter clothes, they rejoiced and took them.

Zheng Hui organized officials to record which families received a few quilts and several sets of cotton clothes -- these winter equipment Li Zhi did not give to the poor people for nothing, these quilts and cotton jackets Li Zhi cost 5,000 taels of silver, and they were to be returned to Li Zhi after the peasants collected the rent in the first year. When peasants plant spring wheat in the first year, it is estimated that each household can earn 23 or 4 stone of grain, and if they dig up food between five mouthfuls, they can still exchange 10 stone of grain for 20 taels of silver, and they can afford to buy some cotton clothes and quilts.

Seeing that the poor people were not well prepared for the winter and that all kinds of expenses were insufficient, Li Zhi was afraid that the peasants would lack miscellaneous materials for the winter, so he simply borrowed five taels of silver from each household to the peasant households, so that they could find their own vendors to buy what they lacked, and made an appointment to repay the money with grain when the wheat was harvested next year. The peasants took the silver with great gratitude, but one by one they were reluctant to use it, and saved it all.

However, with money in hand, these poor peasants really have to rely on when they encounter difficulties.

After settling the peasants, the weather immediately turned cold, and the cold winter came.
