Huang Chengyan took the missing engraving back, pulled out the ruler, looked at it, and couldn't figure it out for a while, isn't the distance between each scale the same as the ruler of the subdivision moment, is this also a mistake?

Seeing that Huang Chengyan didn't understand, Fei Qian said: "Huang Gong, in fact, this question is not too big, but if it is more precise...... Generally speaking, there is nothing wrong with the scale being equidistant from the scale, but this scale is used on water, and like this cylinder, the drip speed is not the same as the speed of half full water when it is full, so this scale is ......"

Huang Chengyan reacted immediately, and immediately called his subordinates to take out two similar small wooden barrels, one was filled with water on the spot, and the other was only half filled, and then they all took a small iron cone at the bottom to open a small hole, and carefully observed the water flow from two wooden barrels with different amounts of water, and sure enough, as Fei Qian said, the size is not the same, and as time passes, the two water surfaces with different amounts of water have dropped differently......

"I see!" Pang Tong, who was also watching from the side, suddenly figured it out and said, "Water also has weight!" This bucket has more water, naturally heavier, and the water flow speed is faster than this bucket, so the scale of this benchmark should not be the same up and down distance according to this situation......"

Huang Chengyan also figured it out, and when he heard Pang Tong say this, he praised: "Shiyuan can, it seems that recently he has not only read the scriptures and history, but also worked Gewu?" ”

Pang Tong was not modest, but a little proud, and said: "That's nature!" ”

Huang Chengyan said to Fei Qian: "Ziyuan is meticulously observant, it's rare to know Gewu so well, it's amazing!" While thinking in his heart, Pang Tong Pang Shiyuan was originally not interested in Gewu, but now he actually understands a little, could it be that under the influence of this Fei Qian Fei Ziyuan?

And that small scale, could it be that it was also made by this Fei Qian?

This Fei Qian Fei Ziyuan really deserves to be a figure valued by Pang Gong, erudite and talented......

Thinking of this, Huang Chengyan said with a smile: "It's getting late now, you two might as well stay here." Pen "Fun" Pavilion www.biquge.info I have asked someone to summon craftsmen, and tomorrow Yuan can have people send the materials needed for arrows here, and then you can start making arrows! ”

Pang Tong doesn't matter, just stay and stay, anyway, the Pang family and the Huang family are so familiar.

However, Fei Qian couldn't help but be overjoyed when he heard it, and half of the stone in his heart finally fell, so he bowed his hand to Huang Chengyan, the head of the Huang family, and thanked him.

Speaking of arrowmaking, Fei Qian is actually a little curious, after all, the bow and arrow is a long-range weapon for individual soldiers in the Han Dynasty, and he happened to meet Huang Chengyan, a master of the Huang family, so he took this opportunity to ask him for advice.

As soon as he talked about the making of weapons, this was Huang Chengyan's strong point, and he had no intention of hiding it because of his bold personality, so he asked his subordinates to fetch a few arrows.

Originally, the party that fired with a bow was called an arrow, and the one fired with a crossbow was called an arrow.

These arrows are very exquisite, although Fei Qian does not understand very well, but the feeling of holding it in his hand is very good, the arrow is sharp, the shaft is smooth, the tail feather is also straight, the overall proportion is coordinated, full of beauty.

Fei Qian held arrows and arrows, and while observing and comparing, he listened to the introduction of Huang Chengyan, the head of the Huang family.

This time, Cai Mao said that he was going to train two thousand archers, so naturally he wanted to do arrows.

The arrows of the Han Dynasty are similar to the impressions of Fei Qian's later generations, which are composed of three parts, the arrowhead, the arrow shaft and the tail feather.

According to Huang Chengyan, since it is an ordinary arrow in the army, it does not need to be Seiko, it only needs to be qualified, so it is not too difficult, if you want to customize a bow and arrow for a person, it is called a complex, not only to have good materials, but also to consider from the length of the hand to the length of the arm, and then from the strength of the bow to the center of gravity of the arrow, all of which must be in line with the person who uses the bow to be called the best, these arrows are actually samples left by someone before they are......

Pang Tong let out an "oh" and said, "Presumably, Fang Cai Hansheng came over to find Huang Gong's arrows?" ”

Huang Chengyan nodded and said: "Exactly, Hansheng's bow is relatively strong, and ordinary craftsmen's arrows can be used, but after all, it is not as good as customized, so I came to my ...... again."

Hansheng? Huang Hansheng? Fei Qian was stunned, this is a cowman......

However, Huang Chengyan and Pang Tong didn't talk about Huang Hansheng anymore, so Fei Qian didn't want to ask, after all, he really didn't know him, and it was a bit strange to ask recklessly, and if he was lying, it would be even worse if he was exposed, so he could only wait for the next time he had the opportunity to understand......

Huang Chengyan pulled the arrow of an arrow off the rod, handed it to Fei Qian, and said: "The arrow is divided into two parts, one is called the arrow blade, and the other is the arrow collar......

The arrow blade is naturally the part of the triangular pointed blade used to pierce people, and the arrow collar is really the first time I have seen it.

According to Huang Chengyan, this arrow collar is used to insert into the shaft, and it must be thin and hard, and the length of the arrow collar must be longer than the length of the arrow......

The arrow is not the most elaborate part, nor is it the most troublesome, after all, the arrow is made of molten iron mold, made and polished in batches, although the requirements are high, but the process is not too much.

The most important process of the arrow is the production of the arrow shaft.

The material used to make the arrow shaft is spring wood.

It is not that there is a tree called spring, but it is better to cut down in the spring, and the tree that is easy to crack in the autumn is to be cut down, and it is a tree that is located on the shady side of the mountain.

But anyway, the materials are provided by the Iraqi, so there is no need to worry about the wooden one......

The most important requirement for the shaft is that it must be straight!

However, the wood is often not necessarily straight, if it is regardless of the direction of the wood grain, the arrow shaft made by direct cutting is easy to break, it is a lower grade, and a good arrow shaft must be along the wood grain.

Therefore, if it is a curved wood grain, it must be manually roasted first, and then straightened and corrected, which is very laborious.

In addition, the polishing of the arrow shaft is also a part of the main working hours, called the "pull rod", that is, the original square arrow shaft is polished into a circle with a special knife, and it should be divided into two times, one rough polishing, one fine polishing, and the wood must be adapted to the wood one day between the two times so that it will not be deformed......

Another point is that when the arrow shaft is processed, the weight of each arrow shaft is required to be basically consistent, otherwise the last arrow is heavy to death, and the next arrow is light and fluttering, and the archer does not scold the mother......

After listening to Huang Chengyan's explanation, Fei Qian knew why Huang Chengyan said it was clever before, if there were not a large number of skilled craftsmen, it would not be easy to make arrows that met the standards......

Although the ordinary arrows customized in the army do not need too many delicate things, after all, there is too much manual work and a lot of time consumed......

And this thing is a consumable, although it is recycled, but it is also easy to damage...... No wonder it is calculated in tens of thousands, Fei Qian's impression is that Zhuge grass boat borrowed arrows and stole how much at one time?

It was still pierced into the boat, and more fell into the water if it was not pierced......

Is there any way to simplify this......
