Liu Xiaojun approached Master Wang and observed carefully, and found that Master Wang's hands were shaking a little.

Although it was well concealed, Liu Xiaojun still discovered it.

He himself has made great achievements in calligraphy. One of the key points of calligraphy is to keep your hands steady and steady. He has been practicing how to keep his hands steady since he was a child, which makes it easier for him to understand what people with unsteady hands are like.

Therefore, one can tell at a glance that Master Wang's hands are unsteady.

Liu Xiaojun continued, “The most important thing in filing is precision control, and a steady hand is one of the most important conditions in precision control.”

When he said this, he paused for a moment and observed Master Wang's expression.

Sure enough, the old man's eyebrows furrowed slightly when he heard the words "steady hands".

Why did this young man suddenly talk about the problem of steady hands? Could it be that he had already guessed that there was something wrong with his hands?

impossible.

Even my wife, with whom I have been married for so many years, didn't notice this. It's impossible for someone who just met me for a few minutes to see through it so easily. I must be overthinking it.

Master Wang raised his hand to wipe the non-existent sweat from his head to hide his emotions.

Liu Xiaojun looked at Master Wang's actions and felt a little relieved.

If his guess was correct, Master Wang's retirement might be related to this incident.

But I came here to become a disciple, not to cure my illness, so I didn’t think too much about it.

"Of course, what I've said is all theoretical knowledge, which is not enough to support my locksmith skills."

"Master Wang, you can freely polish some parts for me that a first-level fitter must be able to do. If you fail, I will naturally leave."

Master Wang had some doubts about Liu Xiaojun.

Although this young man has no experience in locksmithing, he is very knowledgeable about locksmithing knowledge.

There's nothing wrong with giving him a chance to practice.

He randomly picked out a part from the pile of parts, handed it to Liu Xiaojun and said, "Do you know how to scrape it?"

Scraping? Liu Xiaojun raised his eyebrows. Master Wang had just picked the most difficult first-level fitter skill for him!

However, Liu Xiaojun was not worried at all.

Because, he does!

Scraping is the most difficult part of the first-level fitter exam.

It not only requires physical endurance, but also requires the fitter to have absolute control over the feel of the hands.

During the scraping process, you need to constantly judge the degree and effect of scraping by hand. The cultivation of this feeling requires a lot of practical experience. If you don’t have enough practical experience, the probability of failure is extremely high!

Master Wang is worried that he is just talking big but not doing it!

Unfortunately, by the time he had integrated the first-level locksmith skills, he had already practiced the scraping skills in his mind tens of thousands of times.

Apart from anything else, he can scrape ordinary parts with his eyes closed.

After taking the parts from Master Wang, Liu Xiaojun was ready to start.

Scraping is divided into several stages: rough scraping, fine scraping, precision scraping, cleaning and inspection after scraping.

After choosing the right tools, Liu Xiaojun began to take action.

at first.

Master Wang took a quick look and found that the rough scraping stage was passable, which seemed to indicate that he had learned a little.

But this person is not from a steel rolling mill, so he certainly does not have a lot of practical experience. Scraping is not possible without sufficient practice. The precision of the scraped materials will vary greatly and they must not be put into use.

Maybe it’s not even as good as the last one who got a herniated disc from scraping!

The parts I gave to Liu Xiaojun were small parts, and it takes about four hours to scrape small parts.

But a guy like this probably doesn't have the patience to shave for so long, and will give up after a while.

Master Wang no longer looked at Liu Xiaojun, but instead lowered his head and focused on the parts in his hands.

This part was the last task assigned to him by the factory director before his retirement, and he had to polish it to a sufficient degree of precision.

This is the latest improved version of the Butterfly brand sewing machine part, but the precision requirement is too high, so it has never been polished out. He is also worried about this issue.

As for accepting disciples.

The young man in front of me is definitely no match for him. I’m afraid that my attempt to recruit a disciple today will fail!

Let’s think about how to cure this hand tremor problem!

Just as Master Wang was lost in thought, he didn't notice that Liu Xiaojun next to him had already finished scraping.

"It's done. Master Wang, take a look."

"Oh? It was completed in such a short time?" Master Wang raised his head, his face was not very happy, but rather angry.

Just over an hour had passed, and for an ordinary first-level fitter, the scraping progress had only reached the rough scraping stage.

Even for Master Wang, a seventh-level fitter, it would take more than two hours.

But Liu Xiaojun completed it in such a short time, which is simply impossible!

Unless this young man is impatient and perfunctory!

Master Wang snatched the part from Liu Xiaojun's hand and was about to curse when he suddenly found that the part felt surprisingly smooth!

When he looked down, his eyes widened.

this!

Something is wrong!

How was it possible for this young man to shave this part so perfectly?

Unless this young man has learned locksmithing before!

And he learned it from a machinist who was even better than him!

"Young man, do you know other fitters?" Master Wang asked in disbelief.
