Chapter 70 The first river

They tried various methods, and there were problems with the first few spiral groove rollers. The spiral grooves are always not standard enough, and the entanglement is either not enough or the error is too large.

Later, Zhang blacksmith came up with a solution to solve this problem. He used a few threads to wrap around the wooden roller in one direction, and finally marked these lines on the wooden roller, and then began to carve grooves. Finally, he finally made a qualified wooden roller with a spiral groove.

Zhang Blacksmith is an impatient person. If he doesn't do it, he won't say anything. Once he starts to toss something, he will get it out as soon as possible.

Now that after handing over the responsibility of managing the gunfire, he made time, so he simply rushed to this matter wholeheartedly, with several blacksmiths he picked out, several apprentices, and carpenters, all with bedding and rolled up in a gun shed.

Every day, under the leadership of Zhang's blacksmith, these people keep knocking and making various parts for this ripping machine, but the manual error is large. In addition, they have no standard design drawings, so they can only grope to dry. The parts are always not qualified, so they can only be made again.

It took about ten days, and this lair-pull machine tool has begun to take shape in the hands of Zhang Blacksmith and others, and has certain conditions for testing.

So Zhang Blacksmith invited Yu Xiaotian to watch the rifle machine they made.

As soon as Yu Xiaotian entered the experimental processing field as a blacksmith, he saw the horizontal rigging machine, so he rushed over excitedly and began to watch it carefully.

The shape of this worm machine is basically no different from the original machine tool he has seen in pictures and videos, so he began to look carefully at the structure of this simple machine and tried to operate it himself. When pulling the wooden roller with a spiral groove, the wooden stick was spiral The slot rotates slowly in the slot and pulls a long iron rod.

The front end of the iron is a well-structured knife. The knife can be removed and can be stuck in the gun with a gasket so that it will not shift when walking the knife. This aspect is not designed by him. All of them are methods conceived by Zhang Blacksmiths and others. The specific is exactly the knife used by Western gun craftsmen in history. He is not sure that it is different.

The knife is stuck on the iron rod and pulled as the wooden roller rotates. It can enter the knife in the barrel until it is pulled out from the other end of the barrel.

In this way, it is basically no different from the simple pulling of the rifled wire he knows. Next, we can conduct an experiment to see if this machine can pull out a usable barrel with a rifle wire for them.

So Yu Xiaotian immediately asked Zhang's blacksmith to get a few well-built, and drilled smooth-battered barrels and began to test them in the workshop.

The smooth-bouve barrel is stuck on the fixture of the machine tool. After correction, it is stuck on the fixture with an iron wedge and completely fixed firmly.

Zhang blacksmith nervously began to operate the ripper machine. First, he inserted the iron rod that fixed the knife into the barrel into the barrel from the front of the barrel until the head of the knife was exposed from the back. Then Zhang blacksmith took a knife they tried, fixed the knife on the base of the long rod with a gasket, and gently sent it into In the barrel of the gun, it was not until the knife was stuck in the mouth of the gun that he began to work at the other end.

He fixed the other end of the long rod on the wooden roller engraved with a spiral groove, stuck the long rod with pins so that it could not move, and checked it back and forth several times. After calibration, he was ready.

Yu Xiaotian did not do it himself, but carefully watched their operation. Judging from the order of their operation, the steps of the operation of the Western craftsmen in the video he had seen in his memory were basically the same until Zhang Blacksmith and others completed all the preparations and looked at the machine tool nervously. Yu Xiao God nodded and said, "Let's start! Try to see if this guy can use it! Don't be afraid of failure. If you fail, continue to modify it. Now it seems that there is basically no problem. It should be okay!"

Zhang blacksmith quickly nodded and answered, drove the others away, walked to the end of the machine tool in person, and grabbed the handle of the pulling wooden roller.

After Zhang's blacksmith began to pull the handle, the wooden stick with a spiral groove began to be in the slot, slowly rotating to the other end of the machine, and also driving the long rod stuck with the knife, and slowly entered the gun chamber.

There was a slightly harsh metal friction sound in the barrel of the gun. It could be heard that it was the edge of the hard broaching knife and the sound produced on the inner wall of the relatively soft mature iron barrel.

The wooden roller slowly rotated while being pulled out by Zhang's blacksmith. The long rod also drives the knife and rotates while entering the knife in the gun.

In fact, this process is not long, but in everyone's feeling, time seems to have solidified, until the knife was pulled out of the other end of the gun by Zhang's blacksmith. Yu Xiaotian realized that this first river line should have been created by him.

So Zhang blacksmith took off the long pole, and someone immediately took a piece of white paper and came to the other end of the gun. Yu Xiaotian couldn't wait to get to the other end of the gun, closed one eye and began to look through the muzzle of the gun and the inside of the gun.

Because there is a piece of white paper at the other end, he can clearly see the inside of the gun.

In the smooth and round barrel that was originally polished, a clear rotating spiral groove appeared to form a regular yin carving line. Yu Xiaotian almost jumped up happily on the spot and laughed with his big white teeth: "Haha! It's done! This first river is carved out! Haha..."

The whole shed was full of Yu Xiaotian's wild laughter. At this time, he was so happy that he could almost forget it. He couldn't wait to hug Zhang's blacksmith and kiss him hard. He was so shocked that everyone quickly took two steps back, worried that Yu Xiaotian would be crazy, which was troublesome.

The good thing is that Xiaotian's nerve is still big enough, and his endurance for this kind of happy event is still acceptable. He didn't lose his mind on the spot. After laughing for a while, he began to find problems.

"This wire is very uniform, and there should be no problem! It just looks a little shallow! You need to pull it a few times to pull this shady line deeper!"

The blacksmith Zhang also came over and carefully observed the chamber from the mouth of the gun. At this time, he was also very excited and happy. The line looked simple, but it condensed his painstaking efforts of more than ten days and nights, and he did not expect that such a simple method would solve such a big problem by relying on this spiral groove wood. Roller can actually carve such a uniform worm line in a small gun. He really can't figure out how Yu Xiaotian figured out this method.

So he stood up and said to Xiaotian, "Big head, the little ones are really convinced by you! You can actually come up with such a method. If we think about it, I'm afraid we can't think of such a way for a few more years!"

At this time, the craftsmen and apprentices who participated in the trial production of the rifled machine also came to watch the rifled wire in the gun. They were all excited and surprised.

Yu Xiaotian was a little proud, but immediately realized that he didn't invent this thing, and he was just plagiarizing the technology of his predecessors in history, but he immediately thought that the person who invented this kind of engraving has not been born yet. Since he has made this thing, it is even plagiarism. Stealing can only be counted on his head, so he said righteously, "There is nothing difficult in the world, but I'm afraid of people with intentions!" As long as you pay attention, you can actually come up with a lot of good ways! The key is to think more and think more!"

Zhang Blacksmith nodded repeatedly, and then said to the craftsmen and apprentices around him, "Have you heard the words of the big master? You have to pay more attention. Don't just think about eating and sleeping all day, look at the big man. In your busy schedule, you have to think about so many things. You also have to learn more and use more snacks in the future..."

These craftsmen and apprentices quickly said yes. Now in their eyes, Yu Xiaotian is simply a god. With them, he made guns and cannons, made sharp killers, and made a lot of convenient tools and machines. He also came up with the current production method, which can be said to have created one by one. The miracle, if they let them do this kind of thing, they dare not dare to think about it at all, but under the guidance of Xiaotian, they have been done one by one.

So these people admire Xiaotian. They are willing to do whatever they want them to do at this time. They just want to learn a scale and half claw from Yu Xiaotian, which is enough for them to eat for a lifetime.

Next, Zhang blacksmith adjusted the thickness of the gasket of the knife, pulled the handle again, and pulled the knife back and forth several times. After observation, the shady line of the river line had become deeper, and Yu Xiaotian was satisfied.

Zhang Blacksmith continued to work hard, adjusted the knife head, and began to pull the remaining rifled line. After tossed back and forth for a long time, the barrel was completely pulled into a rebar by him.

Yu Xiaotian lay in front of the muzzle and looked at the circle of wires in the gun. He only felt that this was the most beautiful thing in the world. He couldn't wait to sleep with the barrel in his arms. His saliva almost flowed to the ground and danced excitedly.

But he finally controlled his emotions. Now although the wire barrel has been made, there are still some problems with this machine. The base of the knife head is a little difficult to use, and it is very troublesome to adjust, and the quality of the knife head does not seem to be very good. Then he pulled a barrel and the knife edge is It is already a little too sharp, and it still needs to be polished before it can continue to be used.

In addition, there are still some minor problems with this machine, which will not be repeated. Zhang Blacksmith has also found these problems and decided to continue to modify them one by one until these minor problems are completely solved.

But anyway, the first rifle barrel was still taken out by them, and then they waited for the test.
