Chapter 69 - Prepare for trial production of ceramic barrels

After staying up late to finish the first draft of the design, Ye Qing found out with regret. I lack equipment again!

I want to engrave a complete dragon, even a malnourished dragon, on a pistol. The area seems extremely limited, so natural. Except for the sleeve part, part of the derivation must be done under the grip.

In this way, the original shape of the firearm was completely destroyed. The original M1911 frame and sleeves can no longer be used. It had to be re-made. As a result, Ye Qing found that he was missing another CNC cutting machine.

After placing an order online overnight, Ye Qing's purse shrank again. I don't know if it was because of enough sleep or because of the sadness of Franklin's departure. Seeing the white fish belly that had already appeared outside the window, Ye Qing had no intentions.

Put on your clothes, wash yourself, and refresh yourself. Ye Qing got up and walked outside the store, looking at the bright yellow bull in the dawn. Ye Qing took out the key.

On the quiet street, a sudden engine roar awakened many men and women who were still lingering with Zhou Gong. Individuals who are grumpy, "Ma Jafak" blurted out.

And the initiator of all this, Ye Qingye, did not have the consciousness of disturbing the people. On the contrary, blowing a cool wind, racing. Extraordinarily Sa!

As if walking the dog, he lifted himself out for a stroll, and had breakfast by the way. After twisting two more cups of coffee back, Ye Qing opened the door in advance.

The job advertisement posted on the Internet yesterday still received a response, and the interview was scheduled for this morning.

Waiters and convenience store cashier jobs are mostly part-time jobs for students or unemployed aunts in the Silver Eagle Federation. So Ye Qing didn't look for Duke's brothers when recruiting this time.

After a while, a head came in outside the store. He has short pink hair, a large shirt on the upper body, and a pair of shorts underneath. Under the cover of the hem of the shirt, only two large white legs can be seen.

Well, that's a bit inaccurate. Mainly, this girl is a little short...looks even a little underage.

"Hello, can I help you?"

Ye Qing got up with some doubts, and asked as he walked outside the door.

"I'm Gina, here to apply for a waiter."

The girl looked a little shy and lowered her head, and then she seemed to have figured out something. Suddenly raised his head and looked at Ye Qing directly.

"Ah, hello. Please sit down, I'm sorry you look too small. I didn't recognize it."

The other party's words made Ye Qing a little embarrassed, and he quickly reached out to signal the girl to sit down and talk. It's just that this one looked at each other, Ye Qing suddenly felt a familiar feeling in his heart.

"I'm an adult! This is my driver's license, look at it!"

Hearing Ye Qing's words, the girl frantically pulled out her driver's license and handed it to Ye Qing.

Children on the federal side can get a driver's license at the age of 16, and they don't have an ID card. Therefore, under normal circumstances, a driver's license or social credit code has become a common use for federal people to prove identity.

Ye Qingshun, who was already aware of these things, took the other party's driver's license and looked at it. Employing child labor is a felony in the Federation, and Ye Qing doesn't want to capsize in the gutter.

But generally speaking, as long as you have a driver's license. High school students can also go out to do part-time jobs. The moment the other party took out his driver's license, Ye Qing felt a lot more relaxed. The rest of the work is to check whether the person on the driver's license is the opposite person.

"Well, it is. I'm sorry, I misunderstood you. But why do you feel familiar to you? Have you ever come to my shop before?"

After confirmation, Ye Qing returned the driver's license to the other party. At the same time, the familiar feeling came out again.

"Well...and, three months ago, you gave me milk and bread."

Gina was a little embarrassed,

But he nodded and said.  It's just that when she mentioned milk and bread, Ye Qing suddenly remembered. Isn't this the little sister? It's just that Ye Qing didn't react for a while after wiping off the thick smoky makeup.

But let's not say. After wiping off the smoky makeup, the little girl looked pretty cute. Legal loli, is there anything? !

"Ah, I remember. It's you, you look much better today than before. Oh, yes, the salary and working hours are the same as yesterday. The monthly salary is 4000 and two days off. The time is in the afternoon. Four o'clock until twelve o'clock in the evening."

With a smile and praise, Ye Qing began to talk about business.

"As for the work content, you have been to the store, you should know it too. It is to help serve the guests with drinks, and then clean up after the guests leave. It is simple, but a bit hard. If there is no problem, I will get the contract? "

Ye Qing's salary is relatively good. In the Commonwealth, the average hourly wage for part-time jobs is around $10, while Ye Qing's average hourly salary is $13.

Faced with this kind of work, Gina nodded without a doubt. After signing the contract, Ye Qing politely sent him away.

Then Ye Qing sat in the store for a while, and when Conn and Harris arrived, he returned to the studio to start trial production of ceramic barrels. U U Reading www.uukanshu.com

For the barrel, in addition to the hardness of the material, high temperature resistance, pressure resistance and toughness are indispensable. There is absolutely no problem with ceramic hardness and high temperature resistance. After all, the temperature of firing ceramics is not low. Therefore, all Ye Qing's doubts are focused on the latter two properties.

Let's talk about resilience first, which can be understood as elasticity in a simple and crude way. After all, the bullet head is in the barrel of the gun, it is shot out quickly, mounted on the rifling on the barrel, and then rotates along the trajectory depicted by the rifling, and finally leaves the barrel.

In such a process, if the barrel material is simply hard. Then, under repeated impact, the possibility of blasting will inevitably appear. This is unavoidable, including now.

If a gun is used for a long time and the number of shots fired reaches the end of the barrel life, the barrel will not be replaced. In addition to the reduction in accuracy, the risk of blasting will also be greatly increased. This also explains why when many guns are sent to the factory, the manufacturer will provide a spare barrel.

Although the porcelain made from the high-tenacity porcelain clay produced by the system, compared with ordinary porcelain, the toughness is much higher. But in the process of pulling the rifling, whether it can withstand the long period of polishing, Ye Qing is not sure about this now.

In addition to this, there is another thing out of Ye Qing's grasp, and that is the compression resistance. This pressure mainly refers to the air pressure in the barrel.

When the gunpowder in the sub-munition chamber is ignited, the high-pressure gas produced by the explosion will instantly strike the inner wall of the barrel. At that moment, there will be a large difference in pressure inside and outside the barrel.

If the pressure in the chamber is higher than the atmospheric pressure, the barrel will expand outward under the action of force. Therefore, can it withstand this pressure change and keep the shape and structure of the barrel from deformation?

It is also a major test of the barrel material.
