Zhang Guoan's fire cap-type mini step/gun has a simple structure, which is conducive to the hand-made craftsmanship of the Great Song Dynasty. Pen, fun, pavilion www. biquge。 info

It has a caliber of 17.8 mm, weighs 4.8 kilograms, and the bullets are head-shot lead bullets, each weighing 32 grams, and the total length of the gun is 1.25 meters.

The gun through strip is also located in the butt.

At the same time, Zhang Guoan removed the safety lock of the firing part, because a fire cap must be installed before firing, and even if it is misfired, it is also a hammer air strike anvil.

This simplifies the overall structure even more.

Zhang Guoan drew each part accurately, and also marked their various data and overall appearance, of course, this fire cap type Mini step/gun is a little more complex than the arquebus.

Hu Zhenbei blacksmith and other blacksmiths looked at it for a long time and said, "It's not difficult to build, but this so-called anvil is directly connected to the upper and lower holes of the fire door, where is the fire/medicine pool?" Why was the original dragon head with a fire rope changed to a hammer? ”

Zhang Guoan smiled and said: "I have my own way, as long as you can build it." ”

Well, they pulled out two blacksmiths to build this one specifically.

Zhang Guoan went to solve the problem of fire caps.

He did prepare two methods, one is the wrestling/cannon/type fire cap, and the other is the thunder/acid/mercury fire cap.

Dropping/cannons were a common thing for everyone on that plane, and even if they hit people, they wouldn't do any damage, unless they were massively concentrated.

Smashes/cannons do no damage to man, but they are enough to ignite the projectiles.

And its processing is quite simple, in that world, many small / peddlers / / / ) are in the countryside at home to make their own.

Zhang Guoan asked people to file about ten grams of silver dust directly from the surface of some silverware, and then put it into a mixture composed of 70 grams of nitric acid and 100 grams of alcohol, and then heat it slightly. That is, a white precipitate is generated, and the precipitate is removed and washed.

Zhang Guoan used a bamboo knife to gently mix them with 1,200 grams of flour and water, and finally dried them and cut them into small pieces weighing about 0.25 grams each.

Then, he tried it and let it fall to the ground on its own from a height of 50 centimeters. It didn't blow up.

At a height of 150 centimeters, it let it fall on its own, and it did not explode.

He tried to throw himself against the stone again, but it rang.

He realized that he was a dirt road, not the hardened ground that the world was all about.

He tried to make Lei Ong again.

This is simpler, he directly produces nitric acid with water/silver and nitric acid, and then reacts with alcohol to make ash/thunder/gong.

He took the gray sediment that had finally gotten out and carefully collected it. Then gently put it on a porcelain plate and add some tung oil, this is to blunt its responsiveness/sensibility.

He stirred it gently, then spread the mixture flat on a paper-lined table to dry.

It is also cut with a bamboo knife into small pieces weighing about 0.25 grams each.

He tried it again, and found that the reaction was a little slower than the fall/cannon/style, he thought about it for a long time, and decided to use the former, this nitric acid/gong is too dangerous. There is violent/poisonous, although in small quantities. But for a long time, it was too bad for the gunners.

He went to the blacksmiths again.

He gave them the task of making a few small copper bowls, with a radius a little larger than the anvil, thirty millimeters deep, so that the fire cap could not fall off the anvil easily.

It's simple, while they go to build it. Zhang Guoan watched the two blacksmiths hammer a piece of iron slats wrapped in iron rods, and when they were re-burned, they had to sprinkle some charcoal powder on them.

They are replenishing the carbon lost through repeated hammering.

Really, it's too slow.

They did this in advance by beating all the so-called good iron into standard iron slats.

Zhang Guoan also thought about implementing assembly line processing in advance. However, they can't do it with machining accuracy, so it's better to let them work in pairs and build their own little by little.

Before leaving, Song Ziqiang made them a batch of various types of general stop regulations, as well as weight unit weights, which can be regarded as their forced implementation of their own standards.

Zhang Guoan thought, let them cooperate with the practice, and then let them be familiar with the process, and then start to engage in assembly/line production.

At this time, the original captains came to him.

They happily thanked Zhang Guoan that they had found a suitable hillside and began to dig and build a cave kiln, and this time they would dig a bigger one, and they also thanked the little brother he sent for his guidance.

One of the captains who took the lead said: "Captain Zhang, there is an uninvited invitation below, may I ask, can you also let me wait for the salt?" ”

Zhang Guoan said in his heart, sure enough, the people of the Great Song Dynasty want to share the profits when they see them, and this day will definitely come, but they didn't expect it to be so early.

Zhang Guoan nodded and said, "Yes, but where do you find so many people?" You see, who is idle here? Even children have to work------"

The captain who took the lead said happily: "Don't let Captain Zhang worry about it, we will naturally recruit people!" ”

In fact, they have already calculated the input and output of this salt pan, and ninety percent is labor costs.

The captain who took the lead said, "I have the good fortune to know a great salt merchant, and he will devote himself to ------."

Zhang Guoan is happy, look at it, as long as there is a profit, anyone can invest with all their might.

At that time, when I was in Lin'an City, where were the big businessmen to follow up?

The captain who took the lead said, "I know the rules here, and I will hand over 10% of the output------ but can I tell you the secret method of making refined salt?" ”

Zhang Guoan thought for a while and said: "It's easy to say, but I have one more condition, I want 20% of the refined salt you produce!" ”

He can't teach the Great Song people for no reason anymore, he always has to have something in return!

The captain who took the lead felt a pain in his heart, but he couldn't understand how they made it.

Salt, no matter where it is produced, there will always be a little bitter taste, it is born like some, but there is no refined salt at all, it is really a good product, or can it be operated by the official family of the Great Song Dynasty alone?

He agreed.

Zhang Guoan saw that his heart was distressed, but he ignored it.

How much more money can be sold for refined salt, and how much more can ordinary sea salt be sold? They know it in their own hearts.

When Zhang Guoan watched them leave, he was still in high spirits, which was a huge profit.

The blacksmiths made the copper bowl he wanted.

He stuffed the small pieces on the spot, then pressed the copper bowl against an iron rod, and struck it lightly with a small hammer, and the "snap" sounded.

Blacksmith Hu Zhen laughed at the time and said, "I guessed that Master Zhang's family would use this method!" ”

Zhang Guoan didn't bother to ignore him, if he saw a fire hat, it would be hell, bragging.

Then he went to the leather workshop.

At this time, the people in that workshop were very busy. (To be continued.) )
