In the past, although Chen Xian did something that was a miracle in this era, he himself didn't understand the truth very well, and it wasn't until he read the theory of the rich country that he understood these truths.

The foundation work of modern economics was written in the 18th century, and in terms of productivity, it is actually closer to the Great Song Dynasty than to the 21st century.

For people in the 21st century, this is nothing more than a popular science book, but in the Great Song Dynasty, this is an artifact!

Thinking of this, Chen Xian suddenly became full of confidence!

……

These thoughts flashed quickly in Chen Xian's heart.

With a satisfied, even triumphant smile, he walked through the apprentices at work to the northeast corner of the workshop.

Here there is a wooden work platform, the upper surface of which is covered with an iron plate.

On the iron surface of this workbench are a few things that look a little strange.

The first thing is a zigzag thing, this zigzag thing is made of iron, a wooden tray is mounted on one end of the zigzag, the wooden tray can rotate freely on the body, and the other end has a small square hole.

On the upper end of the zigzag, there is a wooden sleeve around the iron.

In modern times, few people know this thing, because this is a kind of manual drilling tool that has been basically eliminated, and its name is "hand crank drill".

The state-owned enterprise where Chen Xian once worked has a long history, and Chen Xian once saw this kind of thing in the old tool warehouse of the factory.

As a history buff, Chen Xian took advantage of his position to get this old antique out of the company and make his own collection.

When this kind of manual drilling tool is used, the wood disc behind the crank drill is pressed against the belly or waist hip part, the drill bit is tightly pressed on the workpiece, and then the crank in the middle of the drilling tool is rotated by hand, and the drill bit at the front end is driven to rotate and the drilling process is carried out.

This is a kind of non-powered hand-held drilling device that was still widely used in the fifties and sixties.

Next to the crank drill was what looked a bit like an office paper cutter, only larger and heavier than a regular paper cutter.

This thing, which looks like a paper cutter, is actually an iron sheet scissors designed by Chen Xian to cut thin iron plates.

The principle of this iron scissor is similar to that of a paper cutter, which is something similar to a guillotine, but compared with an ordinary paper cutter, the torque of the handle of this guillotine is greater, and the base of the head of the guillotine is cast with pig iron, which is very stable and heavy.

There are also a few chisels next to the iron scissors, but the front ends of these chisels are not sharp edges, but a spherical head that is concave inward, which looks very strange.

Chen Xian stepped forward quickly, he was the first to pick up the handmade crank drill, picked up a drill bit with a hammered end into a square from the side, installed it in the square hole of the crank drill head, and fixed the drill bit in the square hole with a few iron wedges.

Zhang Bai took a pair of pliers and clamped a thin piece of iron about an inch and a half wide and three inches long and placed it on a piece of wood nailed to the side of the wooden platform, and a finger-wide groove was opened in this wooden block.

Chen Xian nailed the wooden disc at the back end of the crank drill to his stomach, aimed the drill bit at the position where the wooden groove on the iron sheet and the wooden cushion block coincided, forcefully pushed the drill bit forward, pressed it tightly on the iron sheet, and then began to rotate the crank.

After about two dozen rotations, the sharp drill bit made a small hole in the iron sheet.

Of course, this efficiency cannot be compared with modern pistol drills, but compared with the drawing drill of this era, it is also a small improvement, and the accuracy of this crank drill is also much stronger than that of the pull drill.

Nodding with satisfaction, Chen Xian took the pliers in Zhang Bai's hand, clamped the iron piece, and sent it towards the edge of the iron scissors.

Yang Xiaoyi, who was next to him, hurriedly lifted the handle of the guillotine of the iron scissors and opened the edge of the guillotine.

Chen Xian sent the iron sheet into the knife edge, Yang Xiaoyi pressed the handle hard, Chen Xian stuffed the iron sheet into the knife edge and broke in response, Chen Xian raised the pliers to see that the knife edge at the front end of the iron sheet was neat, like a piece of paper cut by scissors.

At this time, the smile on Chen Xian's face, which could no longer be suppressed, gradually bloomed.

Seeing Chen Xian's heartfelt smile, Zhang Bai and Yang Xiaoyi and several other elite apprentices who were specially selected by Chen Xian couldn't help but laugh along, although they didn't understand why the teacher was so happy to laugh back.

Speaking of these two tools, we have to talk about Chen Xian's recent extremely tortuous mental journey.

Since that confrontation training, Chen Xian affirmed the combat effectiveness of the Mandarin Duck Formation formed by this group of young apprentices under his command, he began to consider updating the equipment of this group of teenagers, as a modern person, Chen Xian attaches more importance to the power of tools than everyone in this era.

The update of equipment starts with simpler weapons.

This is not difficult for Chen Xian, he asked each teenager to use the pig iron processing of 100 steel and Bao Gang method, according to their position in the mandarin duck array, to create a sharp spear head or boring palladium head for themselves, and then Chen Xian personally used the double liquid method to quench, which suddenly made the sharpness of the weapons in the hands of the teenagers rise several levels.

Compared with the head of the gun, Chen Xian was actually more dissatisfied with the bamboo barrel of the weapon in the hands of the teenagers.

At this time, Chen Xian found that Yang Yuanwai was very dissatisfied with the katana outfit he had handed over, and after Chen Xian delivered the goods, he would ask his skilled craftsmen to rematch the scabbard and handle with more exquisite blades.

After knowing this, Chen Xian simply stopped making the handle and scabbard, and directly sent the quenched and ground blade over.

In this way, the carpenters under Chen Xian were idle.

Chen Xian just asked the carpenter team to try to make some high-quality gun handles, boring palladium handles.

Instead of using traditional methods to make the handle, he opted for a more modern process.

Chen Xian hired a few people from the builders under Chen Laojia and bought some hardwoods such as oak and beech.

In this era, there is a lack of everything, but this wood resource is really rich, to be placed before he crosses, not to mention the hardwood in this Lu Mountain, even a decent mature tree can not be found.

Chen Xian asked the builders to take the apprentices of the carpenter group to sawn the hardwood into a five-meter-long section, and then dissolve the wood into planks, when unraveling the boards, he asked to follow the shape of the wood itself, the front of the plank is thin and the back is thick, the front thin part is less than an inch, and the back part is nearly an inch and a half minutes.

After dismantling the boards, Chen Xian asked his apprentices to use a carpenter's saw to cut the planks into strips after tying the line with ink cartridges.

These strips also follow the shape of the wood, and are sawn small in front and large in the back.

Next, Chen Xian asked the carpenter apprentices to file the small and large wooden strips into a cylindrical shape with a file, and finally polish them with homemade sandpaper.

Homemade sandpaper is very simple, that is, the porcelain pieces are crushed with a grinding groove, and then mixed in fish gelatin, and then the fish gelatin with broken porcelain powder is coated layer by layer on a thick linen cloth to dry, it becomes the original sandpaper.

The sanded and polished strips of wood become a high-quality gun handle.

The biggest feature of the handle made in this way is that it is hard, and this kind of hard-pole gun is most suitable for battlefield use.

On the battlefield, fight in formation, no matter how high your martial arts are, there is only one stick left, and the hard-pole gun is the most ferocious, and it is easy to master.
