"Old man, I will use your room and those things these days." Guo Tailai ignored the expressions of the people in the room and said to Old Liu: "Also, you promised to teach me the skills that you can keep in mind, and don't be fooled!"

Guo Tailai left the thing and left. He didn't stop working for three and a half hours. He was so hungry that he had already put his chest on his back. Basically, after saying these words, it was the fat man's limit of tolerance. Without waiting for a few people to respond, Guo Tailai ran away. If he didn't go to the cafeteria, he would have no food.

The anxious Director Li and Manager Wan and his son who were waiting in the office were completely speechless. Have they finished doing it?

Director Li is not just in the office. He also has a skill. Otherwise, how can he be sure how long it takes for fitters to polish manually? Needless to say, Manager Wan is responsible for the front-line production and communicates with senior fitters in the factory in advance. The time is estimated to be much different.

It took only three and a half hours to complete the workload they estimated to have to be a sixth-level fitter for a month. Their first reaction was that it was impossible!

However, this job was done by Mr. Liu, a retired ninth-level fitter, who was supervising the work, and they could not say anything to question, so they could only shout in their hearts. How could it be possible?

"Take it!" Old Man Liu pointed to the box on the table and walked to the chair next to him and sat down.

Not to mention Director Li and Manager Wan were extremely shocked, even Mr. Liu himself was still in fear at this time.

That fat man Guo Tailai took action too quickly, and he was not the kind of method of fine processing at all. He learned basic skills solidly, but his courage to do it was too great, which made Mr. Liu sweat in a cold sweat.

There was only one wire processing allowance. When Mr. Liu went there, he thought the fat man was still carefully measuring the various sizes and compared the drawings. As soon as he entered, he found that the fat man had already clamped the semi-finished crankshaft, holding the finest diamond file in his hand, and filed it on the outer circle of the small head hole of the connecting rod as soon as he filed it.

Mr. Liu almost screamed out loud. Finally, he knew that when hand polishing, he was most afraid of such external factors being distracted, so he forced himself to hold it back. He waited until the fat man's file was in place before he spoke.

"What are you doing?" Mr. Liu closed the door of the small room and then asked angrily at Guo Tailai.

"Machining the crankshaft!" Guo Tailai looked at the angry old man Liu with an innocent look on his face: "Isn't this the job you asked me to do? Don't say, your tool is so powerful, it's so many times more refined than those outside."

"Is there anything you did?" Liu Lao was furious and squirted at Guo Tailai: "Do you know how much processing allowance is? You also need to apply a file. Such a small amount of spare is only enough to grind it! I was really blind yesterday!"

"Please!" The fat man was not used to Old Man Liu's habit of relying on his seniority: "Didn't he just leave a 1-wire processing allowance? What a big deal, do you care if I grind it in place or file it in place? Come on, measure it!"

While talking, the fat man took out a dial meter from the tool box next to him and threw it to Old Man Liu. Really, I had to whine while working. What's wrong with it? If it weren't for seeing the entire fitter workshop respecting Old Man Liu, Guo Tailai wouldn't have been angry.

Of course Mr. Liu needs to measure it. If the fat man doesn’t know the weight of the slight and weight of the diamond file, no matter what the hardness, if you put it on at least three wires, the crankshaft will be useless.

However, Mr. Liu measured several times in succession and measured several positions of the file. The reading of the dial gauge was exactly the same, all 30.010 mm, not bad at all. If one thread was filed off the opposite side, it would be exactly 30 mm in diameter marked on the drawing.

In other words, the fat man filed no more or less, and just 1 thread was removed. The feel and control accuracy were amazing!

Even Mr. Liu, at his peak, dared not say that he could file a thread just right. He had to carefully divide it into multiple times, and file the outer layer bit by bit. Each file had to accurately measure it several times to get the average value before he would dare to continue to do it. How could he do it with a light file like a fat man?

When the fat man changed his position and filed it again, Mr. Liu measured it several times and confirmed that the fat man's hand was so stable that it was beyond the limit and accurate that it was jaw-dropping, Mr. Liu was sure that he had definitely found the treasure.

After three times, Mr. Liu never measured it every time. He just watched the fat man filed and filed the crankshaft that originally required a high-precision CNC machine tool to complete the final finishing step, and filed it bit by bit to the size.

The fat man has a digit in his hands and a digit in his heart. The plane is fine, just need to file it accurately. However, the inner and outer diameters of the large round holes of the connecting rod are round, which is very difficult to process. But in this way, the fat man will do it by filing along the arc curve.

This is no longer the pinnacle, but the skills are almost like the Tao and the magical skills. Old Liu didn't know how to describe the fat man's craftsmanship. Although he was a level nine fitter, he didn't dare to say that he was compared with the fat man in this regard.

The only thing that can be better than Fat is the rich and rich experience over the past few decades. Since the Fatty has such amazing skills, Mr. Liu wishes he could instill everything he knew into him immediately.

So, the fat man started work aside, and Mr. Liu told him in advance what to do, how to do, how to process various corners and curved surfaces, and stuff them into the fat man's mind like indoctrination.

Guo Tailai has a solid basic skills. The two of them are actually very relaxed in their work. They are not as cautious as they are as people outside imagined as they are facing a great enemy. They both chat with Guo Tailai while doing things, studying and working, which is relaxed and comfortable.

During the chat, Mr. Liu learned about Guo Tailai's name and the purpose of coming to the fitter workshop.

Guo Tailai also knew that Mr. Liu was definitely a master. The things he learned from his father were more exquisite, more reliable and more creative implementation methods and techniques, and he was simply a treasure house. Even if Guo Tailai was unlikely to engage in front-line manufacturing in the future, these valuable experiences were definitely what Mr. Guo Tailai dreamed of.

The two chatted relaxedly, and before they knew it, they completed the file and hand-made grinding behind them. After the fat man was about to polish it quickly, the two of them did not waste any more time and took the things back to the office.

It was not until this moment that Mr. Liu realized that the finished product had not been measured by him.

What made Mr. Liu even more shocked was that from the beginning to the end, he had never seen the fat man move the dial meter and had been working, but he had never measured it once.

"Quality...Quality...Quality..." Manager Wan and Director Li held a crankshaft and a dial gauge, and kept measuring the drawings, saying that they were qualified one by one.

In the end, all marked dimensions were qualified, and the inner circle and outer circle were completely standard. They expected that a crankshaft would require a sixth-level fitter to grind for one month, and the fat man completed two in three and a half hours. How could it be?

"How did he do it?" Director Li was going crazy. Is this still a human being?
