Half an hour later, Gu Xiaobai came out of the old man with a bunch of flute materials, and also received a box of flute film and a box of flute film glue.

"I wrote down the formula you came up with, you go try it, and if it works, remember to come back and talk to me. The old man smiled as if he had taken advantage of it.

Gu Xiaobai held the flute material and walked to the direction of the school-run factory next to him, intending to borrow tools.

It is said that it is a school-run factory, but it is actually an internship workshop for students, specially for mechanical-related students to practice, Gu Xiaobai and others have similar internship courses in physics, which are arranged in the summer semester.

However, before this, Gu Xiaobai had not been there.

When he came to the side of the internship workshop, he saw several girls with hard hats, standing at the door and smiling and saying something.

"Hello senior sister. Gu Xiaobai stepped forward.

Several girls turned their heads and saw Gu Xiaobai, and they were stunned for a moment.

Then start screaming:

"Xiaobai-san?"

"Ah, it's junior brother!"

Gu Xiaobai blinked, how did he feel that someone knew me everywhere?

After screaming twice, several senior sisters hurriedly covered their mouths, forcibly suppressed their excitement, and said, "Xiaobai, do you need our help with anything?"

"Well, these are the two senior sisters, I want to borrow a tool to drill a hole......"

briefly explained her intentions, and a tall senior immediately beckoned, as if calling for livestock, and called a senior over: "Old Qin, old Qin, come here, help Xiaobai junior work!"

Qin Chuan was a short and stout boy who was quite dark, with a blank expression: "What are you telling me to do?"

This was the first time Qin Chuan had seen Gu Xiaobai.

"What are you doing, of course it's work!" The tall senior sister gave Qin Chuan a punch first, hit him in the chest, and slammed it.

Then he suddenly felt that he was doing this a little too harshly, blushed and closed his fists, and said, "Lao Qin is...... It's my boyfriend, he can't do anything else, he's the best at doing these rough jobs, and he is the first in every internship, just leave these jobs to him! The drill is so dangerous, don't hurt your hands!"

Qin Chuan: "......"

I can't do it, you don't know? What do you mean I can't do anything else?

And it doesn't matter if my hand hurts.

He looked at Gu Xiaobai and suddenly felt threatened.

Looking at his mother-in-law's face again, he felt that the previous threats must be delusions.

Thinking of her mother-in-law in front of Gu Xiaobai, she introduced herself as her boyfriend, and suddenly became a little happy, as if she was going to fly away even if she was worried.

The other seniors also summoned a few animals to come over, and a group of people gathered around to discuss.

"Is there a formula for making a flute?"

"It's fun, it's a lot more fun than what we do. ”

"Let's go, let's go together!" I don't know who buckled a hard hat on Gu Xiaobai's head, and then a group of students, surrounded by Gu Xiaobai, entered the internship workshop.

Dongyuan University was originally a science and engineering university, with more men and fewer women. When it comes to mechanical majors, the mosquitoes flying in the classroom don't bite, and even the boring holes look like males.

A few girls, although they don't look very beautiful, but each of them has several animals to call, and with such a greeting, the whole department seems to have come.

Gu Xiaobai came to the workshop, originally planning to borrow something like an electric drill.

But there are better tools in the workshop.

Now Qinchuan uses a precision bench drill. The bamboo flute was clamped with a clamp below, the position was adjusted with a ruler, the drill bit was selected Φ6, and the stroke of the drill bit was limited to 5mm, which was enough to drill the bamboo wall, but it would not be overdone at all, and even the speed was put to the low gear.

These bench drills, which are usually used to drill metal, make a hole in the bamboo flute, which is like playing.

If it weren't for the lack of suitable fixtures and woodworking boring machines in the workshop, Qin Chuan felt that he wouldn't have to be so troublesome at all, and he could directly input a set of data into it, and he could drill out all the holes in five seconds.

And now, everything is restricted, as long as you can press the stapler, you can make this hole!

But Qin Chuan still pressed down very seriously and slowly, and Qin Chuan always had an indescribable awe and love for musical instruments, or flutes.

The bench drill is pressed down and raised, and a smooth, rounded blow hole appears on the flute.

"Drill out, drill out!" cheered a group of girls who could drill 10 holes in metal in a minute, as if they had never seen a drill hole before.

"The first. Qin Chuan was still very serious under the watchful eyes of everyone, and raised his head and asked Gu Xiaobai: "Just according to the distance calculated before, and then drill down?"

"Drill. Gu Xiaobai was very serious, as if he was doing a physics experiment.

The flute in his hand is considered to be medium thick and long among all the flutes, and the whole is smooth and straight, and it is also considered to be of the highest grade in the flute.

Gu Xiaobai can be regarded as a tricky eye, and directly found this one from the middle, after Qin Chuan smoothed the inner chamber slightly, he measured the aperture with a vernier caliper, and calculated the length, intending to make a flute in C tone.

For a beginner, it is also necessary to consider which tune to learn the bamboo flute.

Theoretically, as long as you have a big enough bamboo and a long enough breath, you can do whatever you want to tune the flute.

But the flute in different tones has a completely different breath when it is blown.

According to Gu Xiaobai's formula, the lower the flute, the thicker and longer it is, and the larger the volume of air in the tube, the greater the lung capacity required to vibrate, and the greater the spacing between the holes, and the smaller the hand, the smaller the hand.

So the higher the tune, the easier it is to blow.

Beginners usually recommend using the flute in the key of F, but if you are confident in your breath, you can practice the key of D.

Flutes such as A and B are usually chosen by professionals.

Gu Xiaobai's purpose in learning the flute is to verify his formula...... No, it's to practice breath, so naturally you have to choose a big one.

The C-key flute is basically the largest flute that beginners can play.

The old man who gave Gu Xiaobai flute material was also very generous, and he gave Gu Xiaobai three pieces of light C flute material.

In his words, of course, there are consumables for physical experiments, and if you feel sorry for consumables, what other experiments do you do?

But Qin Chuan's hands trembled a little.

"It's a real drill? Qin Chuan was a little reluctant, "You are so confident in your formula, what should I do if the drill fails?"

Seeing Gu Xiaobai's incomprehensible look, Qin Chuan said to Gu Xiaobai: "Don't look at this is just a piece of bamboo, such a good material, if you make a flute in the hands of a famous artist, you can sell it for more than a thousand casually......"

"So expensive?" Not to mention Gu Xiaobai, even his classmates next to him were stunned.

"Well......" Qin Chuan said, "The flutes of famous masters are precious, if a set of flutes are all famous, it will cost more than 10,000 ......."

Studying music is very expensive.

"Just this one bamboo, drill a few holes, so much money? Then I'm going to cut down all the bamboos in our bamboo garden, are I going to make a fortune?"

Gu Xiaobai turned his head to look at the senior who spoke, and he felt that he had found the culprit!
