"Don't get excited, don't get excited, so you know something like a crossbow? Come on, do me a favor! "Hong Tao doesn't know why Carl has such a big hatred for the crossbow, probably because he has suffered a loss. This has nothing to do with himself, what he wants is his understanding of the crossbow, and then let him help him see if the crossbow he made is qualified or not.

Why don't you look for someone else? This is what I asked, the cross bow was contraband in later generations, Hong Tao felt that it should be similar in ancient times, and it was not safe to find someone else! It's not that they're afraid of betraying themselves, but they're afraid of scaring them, and the word rebellion is still terrible at the moment.

The crossbow is the crossbow, and both of these things are the same word in Latin and English. The crossbow is called by the Chinese, and it was first developed by China, and as for when it was transmitted to the West, Carl said that it was not long in the past. The first crusade of the Crusaders suffered the loss of the Arabs' crossbows, and a Crusader knight who had been trained for many years could be killed in an instant by an Arab peasant who had just entered the battlefield with a crossbow. Therefore, the Europeans, including the Church, hated this kind of thing to the core, and although they learned how to make crossbows with the Arabs, the restrictions were very strict, and they were not allowed to circulate at will.

Can Hong Tao make a hand crossbow? Not to mention the hand crossbow, on the Mouse Superman, he even made a mortar, and the mechanical and electrical female workers on the ship were all his personal companions, and he could teach him what he wanted to do. Tired of playing with guns, he sometimes played with antique weapons, such as compound bows and compound crossbows, and used them to shoot fish in the sea. After getting tired of playing, I began to think about dismantling, and after dismantling, I thought about doing it myself, and after making it, I was not interested, and I turned to find other fun things.

What Hong Tao made this time was a very tall modern composite crossbow, but the material was not carbon fiber and alloy, but whale baleen, whale bone, whale tendon, bamboo chips, hardwood and ordinary Song Dynasty steel. Pick the thick whale baleen and grind it into a thin and thick strip of five centimeters wide, one is longer than the other, the longest one is only about 4 cm, and they are perforated and fixed together, and tightly wrapped with fine hemp rope, which is the crossbow arm, commonly known as the flat shoulder.

The thickest rib of the whalebone is selected, processed into a rifle body more than one meter long with a butt, and equipped with a trigger carved from hardwood, which is the crossbow body. It's just that there is no spring, and when the strings are not hung, the trigger will rattle back and forth.

A straight shallow groove is carved on the plane of the crossbow body, high on both sides and low in the middle, which is the track of the crossbow arrow, after being put on, the two ends will be placed in the shallow groove, and the middle is slightly suspended, which is to reduce friction and make the initial velocity of the crossbow faster. However, there are also disadvantages to this, that is, the production of crossbow arrows is very demanding, a little not straight, and there will be deviations after shooting, and the accuracy is not high.

Three magnets are embedded under the shallow groove so that even if the crossbow is erected, the steel bolts on it will not fall. Buckling a straight piece of whalebone, which also has a shallow groove, is equivalent to covering the crossbow arrow between the two whalebones, leaving only a smooth gap, which is where the bowstring is walked. There is also a holster in front of the crossbow, which can be hung on the trigger by stepping on it with your feet and pulling the bowstring with both arms, which is also a lookout for measuring distance and aiming.

If such a crossbow alone is not a composite crossbow, the shooting distance and power are also very average, it is good to be able to shoot people more than ten meters away, but it can only be regarded as a toy and not a weapon. Of course, Hong Tao would not be so unprofessional, he is also a person who has built a modern composite crossbow with his own hands, and even designed it himself, the appearance of his crossbow is very different from other crossbows, even people who have never used a crossbow can see it at a glance.

This difference is mainly reflected in two aspects, the first is the crossbow arm. The arm of his compound crossbow is not bowed backwards, but like a small wing, folded forward from the middle and rear of the crossbow body, slightly opened, and placed together with the crossbow body, it looks a bit like a three-strand fork.

This is called the reverse crossbow, and it is the high-tech of later generations. It can reduce the width of the crossbow body, but does not reduce the firing force of the crossbow, and can also reduce the elasticity requirements for the crossbow arm material, which only needs to be elastic and tough, but does not need to be a long material to be used as a bow arm. Baleen just meets these characteristics, its elasticity is very good, the toughness is not enough, if it is made more than a meter long like an ordinary bow and crossbow, it will be deformed after being used more times, but it will be fine after shortening.

A normal crossbow relies on the force of the crossbow arm being bent backward and then ejected forward to drive the bowstring, while a reverse crossbow relies on the force of the two pieces of the bow being pulled inward and then bouncing outward to drive the bowstring. However, the movement distance of the bow blade of the reverse crossbow is very short, and it can't produce so much elasticity, what should I do? Hong Tao has a way, which is to make up for this shortcoming with a large eccentric wheelset.

The eccentric wheel set is the main component on the modern composite bow and crossbow, which is generally composed of three to five eccentric wheels combined into a group according to a certain structure, and is installed at both ends of the bow and crossbow arm. When you pull the bowstring, the eccentric wheel rotates with it, saving you the slightest effort. But the more you pull, the shorter the center of the circle becomes, and the less effort it takes, until you can wind it with one hand at the end. This is the opposite of a normal bow and crossbow, which is the most labor-saving when it is first drawn, and as the bend of the bow arm increases, the more difficult it becomes.

When the trigger is pulled, the pair of eccentric wheels is at the highest point of torque, and with the help of the elasticity of the bowarms on both sides, the force of the bowstring will be increased a lot, and when the eccentric wheel is turned again, the bowstring will stop moving.

Speaking of the principle of this eccentric wheel set is very complicated, the size and axis position of each wheel in a combination are strictly regulated, and it will almost reduce the effect, or even not work. They are all computer-aided designed, from a group of three wheels to a group of five wheels There are N sets of combinations, and Hong Tao only remembers two of them. One set is entry-level, with three wheels in a group, which is not very explosive but can make the bowstring pull up with a lot of effort. One set is a high-level combination of five wheels, which was developed by the bow and crossbow enthusiasts themselves, and there is no finished product to sell outside, so they all have to rely on their own processing. Its characteristics are the opposite of the combination of three wheels, which is not helpful for drawing the bowstring, but it has a high explosive power, more than half of the compound crossbow of the same level.

"What is this?" Carl followed Hong Tao to the east side of the island, which was a forest where no one usually came. When he saw Hong Tao pluck a strange thing with three strings and two pairs of large bowls from a small tree, he didn't recognize it as a crossbow that he hated so much.

"The crossbow I designed, you can help me identify the difference in range and accuracy between it and your imperial crossbow, so I can continue to revise it." Hong Tao didn't embarrass Carl, but stepped on the holster with his feet, hung the bowstring with both hands, and then lifted the protective cover above, put an iron chopsticks with a sharp end and a round end on it, and clicked the protective cover, and lifted it with one hand.

"This is a crossbow? Great Song's? Karl still didn't quite believe that it was a crossbow, he didn't understand, the bow arm of this crossbow not only did not open, but also shrunk back, and it was almost attached to the crossbow, how to fire the crossbow arrows?

"No, I invented it myself based on the Australian crossbow, come on, let's try the power of the 10-meter distance first...... It's about 11 yards, that's how your yards are counted, right? Hong Tao pointed to a tree in the distance, the trunk of which had been nailed with a rag by him, the size of a human body. Unit! It's still a unit, and now Hong Tao is about to be tossed and stunned by the unit of measurement at this time, and different people want to say different units, no wonder Qin Shi Huang wants to unify weights and measures, it's too necessary!

"Bang...... Airplanes...... Boom! Three different voices sounded almost at the same time, and the crossbow arm in Hong Tao's hand suddenly opened outward, like a flower, and the two auxiliary strings and one main string shrank together in an instant under the drive of the eccentric wheel. Carl was so dazzled by these changes that he didn't even think to see if the bolt had hit the target.

"Hey, what do you see? Look where! Hong Tao saw that Carl's head was a brain collapse before he woke him up.

"Oh...... It...... It can't be pulled out......" Karl ran towards the tree in the distance, and as he looked back to ponder the principle of the crossbow in Hong Tao's hand, the wheels on it really puzzled him. When he ran to the trunk of the tree, he found something even more puzzling, half of the steel chopsticks had already disappeared into the trunk, even if the trunk was softer, the power of this crossbow was too great, if it was shot at a person, even if he was wearing full body armor, it was estimated that it would be doomed! The thought that someone might take this thing at him in the future made Carl, the knight's spine, numb, and he couldn't speak neatly.

"Then don't, I still have it, this time it's 20 meters, probably ...... 21 yards more! I said Carl, you can't learn Chinese, is it so difficult to learn weights and measures? I'll give you two months, and if it's spring, and you still can't figure out the relationship between meters, rulers, yards, and feet, I'll shoot you three times with this thing, and if you don't die, you'll pass the exam, not a humble guy! Hong Tao took out the same steel chopsticks from under a small tree, pulled the string, flipped the cover, put on the arrow, and buckled the lid in one go, and took the time to intimidate Carl, raised his crossbow and aimed at a tree farther away, and quickly pulled the trigger.

"Oh God...... I still can't pull it, it's 21? After Karl heard the three voices, he immediately ran over, his face was even more ugly, the crossbow arrow was no different from just now, it still shot into the trunk of the tree less than half, and the manpower could not pull it out at all.
