Blacksmith Zhang realized at this time that the person behind him should not be the craftsman under him, so he quickly turned around, and saw Yu Xiaotian's angular face at a glance, so frightened that he hurriedly turned around, intervened and bowed to Xiaotian and said in fear: "I don't know if the little one is coming, there are many offenses, there are many offenses, and I hope that the big boss will not be blamed!" ”

"Ha Luha, it's funny, you're doing the right thing, I'm here to disturb your business, you don't blame me, that's it, how can I blame you and so on!" Yu Xiaotian waved his hand and said.

Blacksmith Zhang admires the most is that Yu Xiaotian rarely serves up shelves to these craftsmen, as long as they work honestly, Yu Xiaotian never troubles them, and came directly today without prior notice, which made him make this joke, but he still felt warm in his heart.

So he hurriedly began to introduce Yu Xiaotian to the manual drilling machine he had just transformed, this thing is very large, as big as a bed, there are many parts on it, the barrel that has been created can be stuck on it, the drill bit is inserted into the muzzle from one end, and a large wheel is shaken by manpower, and the drill bit is slowly drilled into the barrel, and the inner chamber of the barrel is bored. It's much faster than all hand-made.

This drilling machine is on the basis of the original, improve the fixture, so that the billet of the barrel is easier and more accurate to be stuck in the correct position of the fixture, so that it is not easy to clamp deviation resulting in boring deviation, in addition, the long drill bit is easy to be crooked, may deviate the gun chamber, even if it is not missed, the tolerance will be relatively large, Zhang Blacksmith is under the long drill bit, and several movable brackets that are stuck in the drill rod are installed, so that the drill bit remains concentric when rotating, and gradually drills into the barrel, so that the tolerance of the barrel bore can be reduced. There will be no more crooked drilling.

After Yu Xiaotian took a closer look at this horizontal manual drilling machine, he was very surprised by the improvements made by Zhang Blacksmith, although these small changes are not big, but they have effectively improved the performance of this drilling machine, making it more accurate and can effectively improve the yield of the drill.

This shows that the blacksmith Zhang has completely entered the role, and began to enter a new realm from knowing what it is, and has found a problem from it, and thought of a solution.

Yu Xiaotian also joined the ranks of Zhang Blacksmith with great interest, and began to personally test the working condition of this improved drilling machine, took a barrel blank made by craftsmen, clamped it on the clamp of the drilling machine, and personally observed the operation of this simple and primitive machine.

Blacksmith Zhang personally went into battle, injected some grease into the barrel for lubrication and cooling, inserted the drill bit into the muzzle, shook the handwheel carrying the drill bit, and the long drill bit began to slowly drill into the chamber.

After some operation, the inner chamber of this barrel was quickly drilled, after removing the drill bit, someone put a blank piece of paper at one end of the barrel, Yu Xiaotian and Zhang Blacksmith both leaned over to observe the situation inside the barrel from the other end, and Yu Xiaotian saw that the inner chamber of this barrel had been drilled very smooth, and the chamber was very straight, there should be no problem.

"Good! Pretty! Hehe! You have changed it so little, this thing is really easy to use, not bad! That's it for now!

And you apprentices, have you seen it too? Lao Zhang has put a lot of thought into it! You should also learn in the future, don't just learn their craft, the key is to spend more time pondering, finding problems, and then pondering how to solve problems, instead of teaching you anything, you will learn what you want, don't think about it, in that case, you can only be an ordinary craftsman, and you will never be able to become a great tool in your life!

Come! Write down this matter to Lao Zhang, tell the council hall, and reward it according to the rules! In the future, no matter what kind of craftsman it is, as long as he comes up with a good way, he must write it down, and he must be rewarded with what he should be rewarded! ”

After Yu Xiaotian saw the working situation of the manual drilling machine after the small change, he straightened up and said to the apprentices and craftsmen around him.

These craftsmen looked at Blacksmith Zhang enviously, both a little admiration, but also a little jealousy, it seems that this machine Blacksmith Zhang has not made much changes, but with such a slight change, it is much easier to use, and the result can receive a reward, now Blacksmith Zhang has improved a lot of things, and has taken a lot of reward, if they can also get it, wouldn't they also have to receive a reward?

Therefore, many people secretly began to work hard, and they were ready to use their brains more in the future, to see if they could also make a little name for themselves like Blacksmith Zhang and win some reward for themselves.

Although Blacksmith Zhang is no longer very interested in rewarding money or not, he is now living a very comfortable life, doing what he likes to do, his wife and children live comfortably, he wants to eat and drink, he really has nothing to ask for, but to be affirmed by Yu Xiaotian is still a very pleasant thing for him, so he thanked Xiaotian again and again.

Yu Xiaotian waved away those apprentices and craftsmen, making them urgently need to do their business, patted Blacksmith Zhang's shoulder, pulled Blacksmith Zhang to a quieter place outside the shed, and said to Blacksmith Zhang: "Old Zhang! I'm here this time to discuss something with you! ”

"Don't dare to be, don't dare to be! If the big boss has any orders, just give them, and the small ones must do it! Blacksmith Zhang hurriedly said.

"That's the case, I see that you are really too busy now, so I want to make it easier for you, this gun is in charge, I want to change someone to do it, you don't want to do this gun anymore!" Yu Xiaotian said.

After hearing this, Blacksmith Zhang only felt a little like five thunderbolts, isn't this equivalent to removing him? He was stunned for a moment, and the boss with his mouth open, stammered nervously and said to Xiaotian: "Big boss!" Be...... Be...... Did the little one do something wrong? This...... This ......"

Yu Xiaotian saw that Blacksmith Zhang was so nervous, and knew that he had misunderstood, so he smiled and said: "You don't have to be nervous, it's definitely not that you did something wrong to take you down and replace you!" You can rest assured that I don't want to use you! It's about giving you some time to do what you'd rather do! As for your salary, no one will give you less in the future, not only that, but I will also give you processing money!

That's what I thought, listen to ......."

As he spoke, he told Blacksmith Zhang in detail what he had thought about years ago.

After blacksmith Zhang heard this, this heart was put in his stomach at once, he breathed a long sigh of relief, a smile appeared on his face, he didn't care about dirty hands, raised his hand to wipe the cold sweat on his forehead, and laughed: "The big boss can scare the small ones to death!" Hehe! I see! That's great! Hehe! I'll have more time to do in the future! ”

Yu Xiaotian also laughed, patted the blacksmith's shoulder vigorously, and said with a smile: "You should wait for me to finish speaking!" People like you should do something that needs to be done, or else, it will be wasted!

So you just have to do what you want to do wholeheartedly, I have a manual here, all of which are some of the things I usually ponder, you can take a look at it, it will probably help you! It's better than digging around on your own, so you can save a lot of effort! ”

Saying that, Yu Xiaotian asked the guards to bring him a large hand-bound notebook, this notebook is very thick, and there are some sketches inside, which are when Yu Xiaotian is free, he collects the memories in his mind as much as possible, and simply draws out some sketches of the mechanical principles he understands in later generations, and even some are simply mechanical structural diagrams, things are very simple, but many of them have not yet been invented.

The reason why he did this was because he was afraid that after a long memory, he would forget a lot of things, and he would not be able to think about it in the future, so when he could still remember, he recorded it as much as possible, one can read it at any time to strengthen his memory, and it can also be used as a backup to pass it on when necessary.

Now he asked Blacksmith Zhang to take out of the miscellaneous gun management affairs, and let someone replace him to manage the gun, and Blacksmith Zhang can put all his energy into what he likes to do, let him toss some new things, and save a lot of his own time, and this note to Blacksmith Zhang, just to broaden Blacksmith Zhang's thinking and horizons, so that he does not have to waste more time in his own pondering and groping, constantly failing to hit the wall, in this guy's lifetime, try to "develop" some useful machinery.

It's a pity that Yu Xiaotian regretted that when he wore this time and space, he couldn't bring a set of mechanical books, and some of the mechanical principles and mechanical structures he remembered were not very many, otherwise, it is estimated that he would not be able to create a mechanical era in ten or twenty years.

But even so, this set of notes he sorted out can still bring a lot of help to the mechanical development of this era, and can more or less "invent" a batch of machinery, which greatly promotes the process of mechanical development in this era, which is much better than being gradually forgotten by him or rotting in the stomach.

He remembered that someone had said that opportunities were always reserved for those who were prepared, so he couldn't miss this opportunity, he had to seize it, which was why he had been very busy since he came to this plane.

Blacksmith Zhang stretched out his hand to take the notebook, but saw that his hands were oily, gray and dirty, so he quickly wiped his hands on the clothes on his body and wiped them again and again, until they were almost wiped clean and would not pollute the notebook, so he carefully took the notebook with both hands.
