Chapter 324

Now the whole gaoshu tribe is based on High-yield grain, steel and cement as its skeleton, and other refined salt, liquor, cigarettes, oil as its flesh and blood. It has formed the rudiment of an industrial tribe.

It is worth mentioning that the last time major hank left, he took some cigarettes and drinks with him. But this time major Adrian Fogg came, he specially asked to bring a batch of drinks and cigarettes back.

Obviously, compared with salt, which is indispensable in daily life, cigarettes and drinks are undoubtedly more attractive to the nobility.

However, Shixiong didn't ask major Fogg to bring back many cigarettes and drinks. He still understood hunger marketing.

Whether it's drinks or cigarettes, even in the UK, it's an absolute luxury in this era. This highly Baijiu and cigarette are rare in this era, especially cigarettes.

Therefore, stone bear plans to use these two things as its main attack in the last ten or twenty years to break into the aristocratic class in the old world, and then exchange a large amount of materials needed here.

As for whether we will add materials to cigarettes in the future, it depends on the specific situation.

For this kind of extra "material", to be honest, Shi Xiong is also in a dilemma. Guco has long been handed down from the South American continent, and the North American Indians also like this plant which can greatly enhance their energy.

However, stone bear knows how to purify guco. Once it is purified, it will not produce the same effect as the "white face" of later generations, but it is also highly addictive

This is Pandora's box. Once it is opened, no one knows what the consequences will be.

What if it spread among the Indians of the new world? Then none of these Indians can be saved

It is also for this reason that Shi Xiong has not made up his mind to add ingredients to cigarettes.

After getting rid of the horses traded with the British, the gaoshu tribe also prepared more and more weapons and equipment for the expeditionary army.

David Addison and Jack Williams are working together more and more closely, and under the guidance of stone bear from time to time, they have made a lot of breakthroughs in various research and development.

This French Alchemist is good at metal smelting. Although he is a man of this age, the stone bear can't catch up with others on horseback in terms of the level of metal smelting. Addison is a professional in metal smelting.

What he lacks now are some forward-looking things, such as how to improve the hardness or toughness of metals.

In this era, people do not know that the key reason for affecting the hardness and toughness of steel is the amount of carbon. At least they have not clearly concluded that carbon can affect various performance indicators of steel.

But under the guidance of the stone bear, adien has now begun to master how to add what proportion of carbon to the molten iron, and then to control the hardness and toughness of the steel. For example, it can be used to make carbon tool steel for drill bit.

The carbon tool steel used to make drills in later generations is T13 steel, which has poor toughness but high hardness, so it is suitable for cutting, cutting and drilling.

Shi Xiong told adian that the carbon content of this T13 steel must be controlled between 1.25% and 1.35%. If the carbon content is too high or too low, it is impossible to smelt this high strength tool steel. And the content of silicon, manganese, sulfur and phosphorus must be strictly controlled.

For this kind of high hardness carbon steel, Addison is naturally very interested. After more than half a year's test in his metallurgical laboratory, he finally produced a high hardness carbon steel with properties close to T13 steel.

Although this kind of steel can't be compared with the real T13 steel, it can be used to process other steels in this era.

Of course, Shi Xiong also told him that adding some other metal elements to the raw materials can also greatly change the performance indicators of steel.

Anyway, as long as it's something the stone bear knows, he will tell edian. Although stone bear does not know the specific performance values of most metal materials, he only needs to tell Addison what elements need to be added to smelt these alloy steels.

As for whether he can experiment, it depends on the skill of this French alchemist.

And Jack Williams got a lot of high-performance steel with the help of dean. With the steel, Williams can try all kinds of processing equipment.

With the joint efforts of the two people, the first deep hole drilling machine of gaoshu tribe was finally successfully made when it came to the full moon (December).

This kind of simple machine tool is driven by water, driven by gear and made of high hardness carbon steel. It can be said that it is the most advanced machine tool in the world.

This kind of machine tool can drill holes up to 90cm in depth. If the depth exceeds 90cm, the workpiece needs to be rotated twice.

Now the barrel length of Ferguson's rifle is 1.4 meters, so if you want to process the barrel of a Ferguson's rifle, you need to drill from both ends.

Before the production of Ferguson rifle barrel is cast, but in the case of using black powder as propellant, it is not a problem. However, in the future, the guns of gaoshu tribe must be fired with non flooded gunpowder (homophonic), so the cast barrel can not be used.

Compared with black powder, the power of non flooded powder is much greater. If the cast barrel is used again, it is easy to explode.

However, for now, the rifles used by the expeditionary army still use black powder as propellant.

But production of new barrels has begun. With specific data, the second, the third and the N drilling machines can be produced continuously.

As for the new broaching machine for rifling, Williams has developed it for a long time. This kind of broaching machine, which also uses water as power, is more efficient than manual broaching machine. If the broach is replaced by the newly developed carbon tool steel, the efficiency of broaching machine will become higher.

In any case, in the past five months, the weapon making of gaoshu tribe has never stopped.

Not only the rifle, but also the barrel. However, compared with the processing difficulty of rifle barrel, the processing difficulty of casting barrel is much lower.

Therefore, the production speed of the catapult is very fast. If it wasn't for the hard casting of the grenade, the stone bear would like to have a catapult by hand.

It's much more difficult to cast a grenade for a catapult than for a barrel for a catapult. From modeling to pouring, even a highly efficient skilled worker can only cast seven or eight grenades a day. The main limitation of casting speed is modeling.

Otherwise, the number of grenades will always be the bottleneck of the large-scale promotion of the catapult.
