Li Wangyou knew that the spring steel of later generations is to keep the steel elastic in the state of quenching and tempering, and it is a steel specially used to make springs and elastic components.
As for how the spring steel was made, he knew nothing about it.
Li Wangyou recalled that he once visited Xi'an Terracotta Warriors and Horses, and there were bronze swords from the Qin Dynasty on display in the museum.He clearly remembered that the explanation of the museum once said that when the bronze sword was unearthed, it was bent at 45 degrees by the pottery figurines.
But when the archaeologists carefully removed the terracotta figurine and took out the sword, the bronze sword quickly rebounded and became straight again.
Since the Qin Dynasty could do it, there's no reason why the craftsmen of the Tang Dynasty couldn't?
He scratched his head angrily, and asked: "Liben, you don't know, is there any steel that can be elastic? Isn't there steel that can be restored after being bent?"
"Teacher, this... this disciple really doesn't know. How about I find a few craftsmen who specialize in making weapons and ask them to see if they know?"
Soon, several old craftsmen who were in charge of making weapons in the ordnance workshop were found. When asked by Li Wangyou, several old craftsmen also looked at each other in blank dismay, not knowing how to answer.
They forged weapons, and what they required was that the steel should be hard and wear-resistant, but they never thought of using steel to make the arms of crossbows.
Although China has iron-bodied bows, the bow body is not made of steel, but metal, bamboo, wood, and ribs are mixed, and iron bars are embedded in the back of the bow.As for the bow arms that can be bent under force, they are still made of bamboo, wood, and tendons.
Seeing all the old craftsmen shaking their heads one after another, Li Wangyou was naturally disappointed.
If this new type of crossbow is made of bamboo or wood, it is not impossible, but obviously its power is far inferior to that of a crossbow made of spring steel sheets.Moreover, if the crossbow arm is made of bamboo and wood, the weight will be much heavier. With his small arms and legs, he is not willing to carry a dead crossbow to hunt.
But since he couldn't use metal spring steel sheets, he could only settle for the next best thing, and fix the other parts of the crossbow first.
At least he had to make a crossbow that he could pull the string and shoot the prey to death from a long distance.Otherwise, after ten days, his bet with the dudes would be lost, and Li Wangyou couldn't bear to send those little nurses in the hospital to Cheng Chumo and his perverts to spoil them.
When he was depressed, an old craftsman rubbed his hands carefully, and said with some trepidation: "Uncle Huxian, the villain once accidentally made a useless sword, the blade can be bent..."
753 Magic weapon
The words of the old craftsman immediately cheered up Li Wangyou.
A sword body that can bend means that the metal used to make the sword already has high toughness and elasticity, otherwise it will be easily broken.
"Oh? Seriously? Where's the sword you made? Show me it." Li Wangyou hurriedly asked.
The old craftsman was a little embarrassed, and rubbed his callused palms again uneasily: "That sword is a waste sword, because it was unqualified, it has been refurbished. But the villain remembers that the villain was Because of mistakes in quenching and tempering, the wrong steps lead to problems with the forged sword body. If Hu County Bo needs a villain to re-forge, the villain is willing to try, but I am afraid that it will not meet Hu County Bo’s requirements. Require."
Li Wangyou was overjoyed. As far as he knew, spring steel was indeed quenched and tempered different from ordinary steel. Murphy, a craftsman, accidentally made spring steel with elasticity?If it is true, then his new crossbow is even more promising.
He quickly said: "Okay, okay, you can try again immediately, I need to make a crossbow arm out of fine steel, if you can make it, I will reward you a hundred taels of gold!"
Hearing that Uncle Huxian was willing to reward one hundred taels of gold, the eyes of the other craftsmen turned red, and they looked at the craftsman who spoke enviously.
They also knew that the old craftsman made a useless sword before.Because of the long sword that this person forged that time, the blade body would be deformed and twisted when it was swung due to an error in quenching.
In the eyes of Tang people, this is naturally a useless sword. For this reason, the old craftsman was severely punished by the workshop steward.
Who would have imagined that this old craftsman would be blessed by misfortune, and it was obviously a mistake that made a nobleman like Hu Xianbo fall in love with him.
This is not a small amount of money, how can we not make them jealous.
The old craftsman was even more excited, and bowed to Li Wangyou again and again: "Don't worry, Mr. Hu County, if the villain dares to be careless, he will definitely make that crossbow arm."
"Okay, what's the need, just tell Yan Shaojian, how long will it take you to make this fine steel crossbow arm?"
"Five days, no, three days, the villain will definitely be able to make it." With the stimulation of gold, this old craftsman is ready to fight.
Li Wangyou nodded in satisfaction: "Okay, since that's the case, then I'll wait for your good news."
If the metal crossbow arms can be solved, the rest of the matter is easy to handle.
Although Yan Liben had never seen the shape of the crossbow body of a modern composite crossbow, it was not complicated. It could be made by a skilled craftsman in a day.
But Yan Liben didn't understand the significance of the eccentric wheel set and the lever-assisted winding device, so he could only ask Li Wangyou about its use and structure in detail.
After listening to Li Wangyou's explanation, only with these organs and structures, Yan Liben's head shook like a rattle drum after winding the crossbow with very little effort.
"Master, how is this possible? If the arm of the crossbow you designed is made of fine steel, the pulling force must be astonishing. The tension of the crossbow used in the military today is about two stones to two stones four, but this A crossbow, I guess it must have at least three stones, and it can’t even be higher. How can such a strong crossbow be stretched by manpower alone? My disciple estimates that such a strong crossbow is impossible to use alone.”
Li Wangyou could only be patient, and explained to Yan Liben what is a pulley block, what is an eccentric wheel, and what is the principle of leverage.
Fortunately, although he is a scumbag, he still remembers the physics knowledge in junior high school, and he can barely deal with Yan Liben's problem.
As for what he couldn't remember clearly, he could only prevaricate and let Yan Liben figure out a way to do experiments by himself.
Yan Li himself was a general and junior supervisor. Although he had no knowledge of physics and chemistry, he was also proficient in mechanism structure. After listening to Li Wangyou's general explanation, he understood the design of this crossbow.
Thinking about Li Wangyou's desire to build a crossbow, Yan Liben couldn't help but gasp: "Master, if such a strong crossbow can be built, it will be an amazing weapon. I guess this crossbow can easily hit even if it is a direct shot." A goal a hundred paces away."
There are several kinds of military crossbows in the Tang Dynasty, the Fuyuan crossbow has a range of 230 steps, the breaking Zhang crossbow has a range of [-] steps, and the horn bow has a range of [-] steps.
It sounds like this range is very scary. You must know that Datang's step is about 1.5 meters compared to later generations. In conversion, even the shortest range, the horned crossbow dedicated to cavalry has a range of 300 meters.
The assault rifles of later generations usually have an effective range of only more than 200 meters.
Naturally, this is not because the power of the crossbow of the Tang Dynasty surpassed the firearms of later generations, but that the range refers to projectiles.
Whether it is a bow or a crossbow, the main combat method in war is not direct fire, but projectile.
Shoot crossbow arrows into the sky at a certain angle, and use the acceleration of gravity and the principle of parabola to increase the range and lethal power of the crossbow arrows.Similar to the principle of later generations of artillery, the angle at which the bow and arrow will be fired, and the area where the bow and arrow will fall, have already been calculated.When fighting, crossbowmen will follow orders and shoot enemy troops at different distances from different angles and covering a large area.
Therefore, the bows and crossbows in ancient China often said that they had a range of hundreds of steps, but they all referred to the throwing distance.But if it is used for hunting or hunting individual targets, it can only shoot directly, and its effective killing distance is quite short.
For example, the breaking crossbow used by pawns in the Tang Dynasty can shoot 230 steps when projected, but the direct shot must maintain lethality, and the range is only [-] steps at most, which is about [-] meters.
No matter how far away, even if you hit the target, there is no lethality.
Li Wangyou believed that even if the new crossbow he asked Yan Liben to build for him could not reach the 200-meter range of the modern composite crossbows of later generations, it should still have no problem at 150 meters, and it could be called the most powerful crossbow in the world.
Yan Liben carefully put the crossbow blueprint drawn by Li Wangyou into his arms as if he had found a treasure.
"Master, don't worry, this crossbow, the disciple will be able to forge it!"
"Haha, that's good. I made a bet with Cheng Chumo and the others. After ten days, I will take this bow and crossbow with them to go hunting. Liben, please work hard. Be sure to help me get this crossbow within ten days." Make it out. Hehe, when you win the bet for the teacher, you must make those bastards look good!"
When Yan Liben heard this, the corners of his mouth couldn't help twitching a few times.
My teacher is too unreliable, such a magic weapon is not for building to equip the Imperial Guards of the Tang Dynasty, but for betting with dudes...
If Li Wangyou hadn't been his teacher, he might have exploded on the spot.
Such a magical weapon, can it be used for children's play?
Yan Liben's face was flushed red, but he really didn't know what to say, so he simply saluted Li Wangyou, out of sight and out of mind, and hurried away to find a craftsman to start making crossbows.
Li Wangyou didn't notice his disciple's expression. After leaving the matter of building a crossbow to Yan Liben, he began to think wildly again, wondering if he should build a set of more prestigious armor since he was going to hunt?
