"Yes!" All words can only become one "yes" in the end.

"Okay, let's talk about more important things now. How is the 16-pounder cannon going?" Alphonse asked again.

"Currently we are making wooden prototypes, and the design drawings have come out." Yasuo Chris took out a piece of Zou Baba's papyrus, on which was drawn a beautifully decorated cannon. The approximate dimensions were also marked, except for the cannon body.

The thickness has been increased by a full 0.5 inches! But it is a sample after all, so thickening means thickening. Just modify it when the finished product is finished.

"The painting is good, but my sample will be tested directly until it explodes, so it does not need any decoration." Alphonse glanced at Yasuo Chris calmly and said calmly, this rough man has an artist in his heart.

, whether it was the Falcon Cannon or the current 16-pounder cannon sample, he wished he could turn it into a work of art.

"Ahem... If you have to test fire until the chamber explodes, I think the barrel wall can be adjusted to the extreme." Yasuo Chris took the tissue paper awkwardly, and changed the size at once with a swipe.

I returned the portion provided by Alphonse...

"Where is the inner mold?" Alphonse asked again.

"This is the most troublesome part, Alphonse. We are molded in one piece. This time the gun mount is almost completely enclosed (only one air port is left to install the flintlock engine). This means that we cannot add water inside to cool the gun.

The body, the cannon wall cannot be strengthened, and it is not as smooth as before. I am still trying to think of a way." Yasuo Chris scratched his head and replied, taking advantage of the self-tightening of the cannon body, Yasuo Chris really couldn't bear it.

Give up.

In fact, for this kind of semi-enclosed gun barrel, the optimal solution should actually be hydraulic self-tightening and impact rolling. Both cost and quality are very optimistic. But this is something after the 19th century. Currently, even in the 17th century

Before it’s over, Alfons really can’t make an entire heavy industry technology tree directly span 300 years of time and space...

Suddenly, Alphonse thought of another terrible thing and looked at Yasuo Chris with wide eyes: "What the hell, are you still planning to use a cast iron inner mold?"

"Isn't it possible?" Yasuo Chris was stunned at first, and then he felt something was wrong. He picked up the design drawing and looked at it, and finally found that the barrel was wide at the bottom and narrow in diameter. If it were cast with a cast iron inner mold, it would be

Finally, how to remove the mold? "Ahem, mistake, a small mistake."

"Go away, it's a good thing you haven't started casting molds yet, otherwise I would directly deduct your salary to pay for the mold orders!" Alphonse complained viciously.

"Hehe..." Yasuo Chris scratched his head in embarrassment and accompanied Alphonse to inspect the artillery assembly line inside before sending Alphonse out. Suddenly he reached out and pulled Alphonse.

Si, whispered: "Alphonse, straighten the cannon body."

"Why?" Alphonse turned around and asked.

"Mold, if our gun barrel is straight, then our artillery can be produced as fast as a rapid-fire cannon." Yasuo continued in a low voice: "Now our output is so large, but the labor cost is so low, that's why

Our molds are very easy to use, but if we also used sand molds, the problem of trachoma would be fatal."

This sentence gave Alphonse a headache. The word "straight" becomes more and more false as the timeline goes forward. If there is no certain elastic range, in this era when even measuring tools cannot determine straightness, it is obviously straight.

When the iron pillar is put in, it may have become curved unconsciously when it comes out. Especially when the diameter is further enlarged, an iron pillar less than 13cm thick must be more than 300cm long, and it is also

It has to withstand countless times of heating, cooling, reheating, and cooling again. The variables are so large, and coupled with metal fatigue problems, it is hard to think of making it into a standard product, but most of the results are not even as good as defective products...

But after all, Yasuo is limited by the times and culture. It is difficult to understand these problems. He always feels that he can apply existing experience. This makes it difficult for Alphonse to explain. He was silent for a while, and felt that it was necessary to talk to Yasuo for a while.

To discuss technical matters, he thought for a while and said: "Yasuo, have you ever thought about it? This time the cannon is more than 3 meters long, and the caliber is only sixteen French pounds. If you make a cast iron mold like this, you can

How to ensure that it will not be bent or deformed by bumps and bumps during use?"

"This..." Mold damage is indeed a problem. After all, although the current technology can cast higher-hardness high-carbon steel, if the more brittle high-carbon steel is bumped, the loss may be even greater.

"As for the mold, I have thought about it. What do you think about using ceramics?" Alphonse asked.

"Ceramic? Isn't that more fragile?" Yasuo rolled his eyes and felt breathless.

"Ceramics are naturally more fragile, but their surfaces are smooth and will not deform. We don't need exquisite ceramics. The key is to have a uniform shape. After drying in the sun, they can be glazed and fired in large quantities. It doesn't matter even if it cracks. It is just a one-time use.

Although the mold is a little longer, there are no technical problems with the 3-meter length. The most important thing is that it is hollow. We can still fill it with water to cool it, and then crack it. The water will evaporate directly against the wall of the artillery tube. Of course

, we can only do this after it has cooled down a little and set." Alphonse said.

"I have never thought about it, or in other words, no one has ever done this, using expensive ceramics to make disposable molds?" Yasuo smiled bitterly and continued: "Okay, even if I accept it, you can find a suitable one.

Does the factory make such large quantities of ceramics for you?"

"Yasuo, it's actually not much." Alphonse also smiled bitterly and shook his head: "This is 1,000 livres. No matter how stupid the Dutch are, they can't purchase it in large quantities. We have a hundred artillery pieces a month.

Thank God for the orders, and its orders are easily saturated. I even only plan to produce 60 doors a month. In this case, as long as we find a factory that can place the order, they may be able to complete our order in a week.

."

"Uh... that's right. If you're free enough, you can even find a few people to customize it yourself. After all, just one stove is enough for you." Yasuo thought about it. This is an 18-pound cannon, which costs at least five or six hundred dollars.

The profit of livres, even if you deliver two doors a day, you can make thousands of livres! I just don’t know how much I can get...

Early the next morning, Alphonse, who had written letters to Darren Desai and Will Morty respectively, saw Alfred leading a handsome and tough young man into the study.

"Mr. Alfred, help me send these two letters to Uncle Darren and Uncle Will respectively. I have something urgent and need their help." Alphonse decided to entrust the matter of the ceramic mold to these two trustworthy people.

Uncle helps. After all, they have many years of social relations. They can easily find ceramics masters who can make molds, and at the same time they can help themselves hide their identities. After all, no one knows what they are doing making these ceramics. If possible, Alfons even

I plan to stock up on thousands of molds at one time. As long as I store them carefully and produce them again every two years, God will not know and ghosts will not notice.

"Yes, sir. In addition, this is Mr. Bardis de Gaulle. He is here as invited." Alfred bowed and said.

"Hello, Major de Gaulle." Alphonse stood up and handed the envelope to Alfred. He walked up to Badis de Gaulle and stretched out his hand to express welcome.

"Hello, Mr. Moller, just call me Badis. I have retired." Badis de Gaulle shook hands with Alphonse, while Alfred calmly went on his own.

Leave.

"Although you have retired, the experience you have is still enviable, Badis." Alphonse motioned for Badis to sit down, smiled and walked to the small bar and continued: "What do you want to drink? Brandy?"

Champagne or whiskey?"

"Just red wine, Mr. Mohler." Bardis also sat up straight on the sofa.

"Just call me Alphonse, that's what all my friends call me." Alphonse smiled, poured two cups of coffee, came over, put one cup in front of Badis, and then went to the other side of Badis to mind his own business.

He sat down and said with a smile: "Is this your first time in Calais?"

"No, it turns out that when I was serving on the Marigold, I often had to dock in the Port of Calais, but that was a few years ago." Badis was obviously taciturn and only answered Alphonse's questions matter-of-factly.

There is no intention to expand at all, which shows that his unpleasant personality is also one of the reasons for his retirement.

"I remember that the Marigold is a small frigate. Are there pirates near Calais?" Alphonse continued to ask with a smile.

"They are mainly privateers. The sea has never been peaceful, and we are not the strongest party." Badis thought for a while and replied. In a very simple way, they are the military's fault, mainly to beat other maritime powers.

privateer.

"What do you think of Marigold's naval gun? You can introduce it to me in terms of accuracy, range, power or rate of fire. You probably also know that I have an artillery factory and I need to constantly improve my products." Ah.

Fang Si smiled.

"The Marigold is a small ship with a single gun deck. It has a 36-pound mortar at the bow and two 12-pound guns at the stern. The deck is equipped with four 24-pound long-range guns, eight 18-pound long-range guns and four 9-pounder long-range guns.

Judging from the literal data, the pounder gun has no shortcomings in terms of firepower, range, and rate of fire." Badis slowly said: "But if you break it down and analyze it, it is actually no stronger than a large armed merchant ship."

"Oh?" Alphonse expressed great interest and motioned for Bardis to continue.

"Because the range is less than 300 meters, during the two years I served, the 36-pound mortar was fired in less than a quarter of the naval battles, with a record of 0. This shows the intimidation effect of the company.

, are very worrying." Badis complained: "The real threat is the 24-pound long-range gun. As long as it is lost within 30 meters, just the waves can kill one or two of the opponent's artillery, but when the 24-pound long-range gun is fired,

The speed is not very high. It takes an average of five minutes to fire one cannon. The four cannons are placed on both sides. Although the French artillery has the highest hit rate, the hit rate of about 3% means that there is basically no hope of hitting in a whole naval battle.

."

"Well, what else is there?" Alphonse smiled.

"On the contrary, the eight 18-pound long-range guns are the real main output. They can fire one shot in two minutes. Although the power of near-missile ammunition is reduced, the hit rate at a distance of 300-500 meters is quite high. If you only hit the enemy once in a naval battle,

If you fire artillery shells, they must be fired by 18-pound cannons." Badis continued: "As for the 9-pound cannon and the 12-pound cannon, they can really only hit pirates. Near-miss shells fired within 300 meters have no power.
Chapter completed!
