Chapter 16 Preliminary Design

Mr. Schmidt arranged the trial production area in a workshop in the easternmost part of his factory. The processing equipment in the workshop is covered with tarpaulin, and there is no equipment to be seen, which is estimated to be the result of the factory's reduction in production capacity. There is a two-story workshop office in the workshop, and when they come to the office, Gross and they are already waiting there.

After greeting her, Ms. Shalotte said directly: "Fang Wu, Mr. Schmidt agrees with you. Their confidentiality agreement has been signed, Fred, you sign it first, and I'll go through the notarization. You talk slowly. The three of them signed the paperwork under the direction of Ms. Shalotte.

After sending away Ms. Shalotte and Dawu, Gross introduced the tester to Bauer Stein, who was originally a test gun at the Mauser Arsenal and later worked as a porter in the factory after losing his job.

It's good, they're all very familiar with firearms.

Drinking the coffee brought by Bauer, I asked Gross to introduce the Mauser rifle, G98, K98, k98b, k98az ......, there are many models, and it is quite complicated. After listening to it, it became clear that 98k had not come out at this time, and watching Fred listen to it with relish did not interrupt Gross. It took more than an hour to explain the development of the Mauser rifle, and fortunately Gross was a true expert.

In summary, there are three different calibers such as 7.9mm, 7.65mm and 7mm, and the barrel is available in two lengths, 29.1 inches and 23.6 inches, and is produced in Germany, Belgium, the Czech Republic, and Austria.

"Fang Wu, what are we going to do?" Fred asked.

Ignoring Fred, he remembered that he had used a Mauser rifle with a bolt pull down at the club, and at the time he thought it was a 98k, so he asked, "Mr. Gross, what is the model of a Mauser short rifle with a bolt handle bent down?" About the same size as rifles of Czech production. ”

"I've seen it, it's Mauser's latest product, it is said to be for the Ministry of Posts and Telecommunications, and I haven't heard of the model yet!"

"Fred, let's sort out the problem, firearms, bullets, scopes, verification sites, and cooperation personnel, five parts. Let's come one by one. I said.

"Fred, what's going on with the scope?"

"Zeiss has 3x, 4x, 6x sights, 8x several samples, and there are no 10x yet." Fred said.

"Fred is in charge of the scope, 2 for 4 times, 2 for 6 times, at least 1 for 8 times, and 10 times to discuss with others to see if we can try to make a few." Seeing Fred nodding and continuing.

"The verification site should be able to place 100 yard and 200 yard target positions, and there should be a shooting table that can hold the firearm, and only the handguard part of the firearm can be fixed. Mr. Stein is responsible for this. ”

"Okay, call me Bauer."

"Cooperating personnel, who is responsible."

"To cooperate with the workers in the procurement and renovation, Mr. Schmidt arranged for me to communicate and coordinate." Gross replied.

"Who is responsible for filing a patent?" I asked again.

"Ms. Salotte is in charge of the declaration, and I cooperate with her." Gross replied.

"Okay, prepare 10 of Mauser's latest rifles, the kind used by the Ministry of Posts and Telecommunications, and 10 Czech Vz-24 rifles, 1,000 rounds of 7.92mm Mauser rifle pointed rounds. Bring in what you have. I commanded.

Gross wrote a slip and signed it, handed it to Bauer, and said, "Give it to Daniel, let him get as soon as possible." You go to prepare the field and the shooting table. ”

"Fred, Mr. Gross, I went through the whole project in several steps. You need to be clear, and you also think carefully about whether it is appropriate, and if there are different opinions, we will find time to discuss them.

The first step is to do verification, which is divided into two parts, one is to do preliminary verification after bringing the firearm and bullets, and the second part is to process the special barrel verification. If the initial verification is obvious, the second part will be carried out at the same time as the second step, otherwise the two parts of the verification must be completed, and if the two parts of the verification are not satisfactory and do not meet our expectations, then the entire project will be terminated. ”

Seeing that they understood, he continued: "The core of the second step is the transformation of firearms, the modification of bullets, the design and production of new guns, the registration of companies, and the formation of basic teams at the same time. A few guns can be modified, the purpose is to give Fred a preliminary practice and prevent the new gun from being too slow to form and affect Fred's participation in the competition. Of course, it's important for our business to compete with a new gun, so we can't afford to slow down. Of course, Fred will be busy, and Mr. Gross and I can't help you. ”

was despised by Fred.

"In the third step, while Gross continues to improve the new guns, Gross and I will develop other new firearms. Fred started marketing immediately after the race. ”

"The fourth step is to think there's a good idea to discuss and finalize together after Fred's game, and Fred can't be distracted until then. If it works, it's my last assignment before I return home. ”

Let's discuss the four steps in detail.

Seeing that the time was already noon, "Fred, I will discuss the matter of special barrels with Mr. Gross in the afternoon, where are you?" ”

"There is a restaurant in the factory, and in the afternoon I go to the Berlin branch of Zeiss and I will take you home when I come back."

The factory has a restaurant for senior executives, who are not interested in tasting anything, filling their stomachs, and Gross is back to work directly in the office. He made a pot of coffee and handed Gross a cup.

"Mr. Gross, although I like to shoot, I don't know a lot about firearms, I'm too professional, I still need your advice!"

"Mr. Li, you're welcome, I'll try to answer clearly!"

"Does the number of rifling on a firearm have a big impact on the accuracy of the shot?"

"Theoretically, a larger number is better, and we have done some verification, and the result is that the impact is not very significant."

"Well, what about the length of the rifling?"

"This empirical formula affects the speed of rotation of the bullet, the slow length of the bullet, and the fast of the short one."

"What are the metals that can be plated now? For example, chrome plating. ”

"Zinc, nickel, cadmium, gold, silver, etc. are also commonly used."

"I see, do you have a drawing of the barrel?"

"Yes!" Sure enough, Gross pulled out a full set of drawings for the firearm.

Looking at the barrel drawings, I thought about it for a while, and I felt that it was better not to make big adjustments at present, and some problems would be better for gradual verification and improvement later.

"Mr. Gross, the barrel of the verified gun should be heavy, and the wall thickness should not be lower than that of the machine gun."

"It's going to add a lot of weight." Gross said as he took notes.

"It's not a problem, the aim is to reduce the impact of vibration. The first is to consider the 29.1-inch and 23.6-inch lengths for the time being. ”

"No problem." Gross nodded.

"The second is to have two kinds of 4 rifling and 6 rifling, and the length of the rifling is determined by you."

"No problem."

"The third is to cancel the original sight. The muzzle part is designed with a thread of 1 inch to 1 and a half inches. Fourth, the guide slope in front of the rifling should strengthen the accuracy requirements. ”

"No problem."

"Half of the barrel is chrome-plated and hard chrome polished, how much chrome do you think is appropriate?"

"If it's too thick, it's uneven, 30 microns! It will add a lot of cost, which is estimated to be a third of the barrel. "I remember that in my previous life, it was generally hundreds of microns, forget it, people still know the current level of craftsmanship.

"Cost is not an issue at the moment. If you think of a flame suppressor that this gun can use, I would like to think about it too. We'll talk about that tomorrow. ”

"Okay, no problem."

Well, it's all fine, worthy of a firearms engineer.

"The barrels, preferably made in the Czech arsenal, are preferably 10 of each, half of which are chrome-plated. Or as little as they can accept. It's going to be hard for Mr. Gross to draw. Oh, and forgot about something, you considered adding some heat slots to the outer wall of the barrel. The anti-corrosion of the barrel is not treated at present. ”

"Alright, I'm going to work!"

Speechless, it's not work to discuss it together? Forget it, there's no way to deal with technology, let's go for coffee.

It's easy to wait until Fred comes back and says that the scopes, tomorrow their Berlin branch will send 6 times and 8 times, 10 times it will take time. Then I said hello to Gross and ran away, and it was almost five o'clock when I got home.
