Zhao Xin had also thought about it before, laboratory products, it is definitely impossible to mass produce them, in Dingjun, there is a complete set of laboratory products, the process of conversion to industrial products, many times, it is enough to follow this process.

When he first saw this smoothbore gun, he thought so, for the premise that the longbow is the mainstream weapon at present, it is acceptable to slow down the production speed.

But no matter how slow it is, Zhao Xin didn't expect that it would be slow to such an extent, 2 a day, if this is a matter of scale, it is also acceptable, big deal, increase enough investment, increase the scale.

In any case, Zhao Xin didn't expect that not only was it slow to the extent of 2 per day, but it also directly limited the source, 4 master craftsmen, this is not all of the Dinghai Navy, it is already the majority.

It is unacceptable to use master craftsmen to build gun barrels, such master craftsmen, in the entire Dinghai Navy, among the 400,000 laborers, there are only less than 10 people, even if all of them are invested in making gun barrels, it is only 5 a day, that is to say, it will take more than a year to ensure more than 2,000 smoothbore guns.

This speed is too slow, not only is the speed slow, but if all the masters and craftsmen are put on the task of building the barrel, it will be a damage to the entire Dinghai Navy.

In Zhao Xin's opinion, master craftsmen should do more important things.

Zhao Xin doesn't know what level the eighth-level fitter is, he can make a qualified barrel from an iron pipe, it took 2 days to make a qualified barrel, such an ability, not to mention the eighth-level god-level level, the sixth or seventh level should be able to do it, under the production of the Dinghai Navy, with steel as the main body, such workers, there is a stage for them to perform, and they do those things with better results, and the help for the Dinghai Navy is also the greatest.

In fact, Dingjun's steel production is so huge, but many of Dingjun's products are not the structure of steel used, some so-called machines, only the key place is steel structure, and many other structures are not steel, but wood.

As the most important material of the earth's civilization, steel is cheap and malleable, which is its characteristic, and when steel is used as a machine, it is very durable, can be used for a longer time, and is also reliable.

Through the promotion of the steel plant, the output of the Dinghai Navy is now as high as 2 million tons, and this output is enough to support the machine replacement of the entire Dinghai Navy, but under such favorable conditions, the Dinghai Navy still gave up better materials and chose wood, the reason is very simple, the Dinghai Navy is already very good in the material, but it cannot be on the processing capacity.

Steel needs to be processed before it is used, and those steel castings that are directly completed are often less important materials, cast on large steel materials, which have natural advantages, but this thing must also wait until simple processing, for example, bulldozing some burrs, and polishing some connected places before it can be used.

In the production of some miniaturized and high-precision machines, there are few direct casting, and it is often a method of creating a rough blank and then processing.

In later generations, it was a very simple thing to process steel, and a simple handicraft workshop with the most advanced machine tools could process iron, but in this era, such an idea was almost impossible to achieve.

With a master of ferroalloy like Niu Dali, and Zhao Xin a strong man with a card system, on top of ferroalloy, the hardest alloy produced in the laboratory has exceeded the hardness of 6.3.

On the hardness standard, the hardness of 6.3, if you take into account wear resistance and toughness, can already be used as a cutter head for processing steel, even if it is not steel, there is no problem with iron.

In fact, such a thing as a cutter head has already been produced, and Zhao Xin was also preparing for the machine tool at that time, and the history of research is very clear about the improvement of the industry after the emergence of the machine tool.

At that time, Zhao Xin was also full of joy, and wanted to make Dingjun transform from a handicraft workshop and a simple machine to a real mechanization, but in the end he found that it was useless, there was not enough power to promote, and it did not have much effect.

The cutter head of the machine tool, only under the premise of stability and uniform speed, can be used, similar to the current animal power of the Dinghai, the error caused by the unbalanced use of simple animal power, has exceeded the knife itself, before there is no stable power, rashly enter the machine tool, that is the risk.

Simple manual machine tools, which have been made, can only be used for wooden structures, the power brought by manpower, the ability to cut wood, is already the reason why the cutter is good enough, steel, that is almost impossible.

Whether it is a drilling machine, a boring machine, or even a comprehensive machine tool, even if Zhao Xin does not understand its principle, the basic structure can still be made. For those professional researchers, a little research for a while, may not be able to make a high degree of accuracy, the basic is still okay.

These are all machines that have a huge role in promoting production, the world of later generations, the basis of the rapid development of all aspects, is the machine tool, in the high-tech field, the most cutting-edge machine tool, enough to affect a country's war strength, more than three axes of machine tools, for China's embargo, enough to make China's weapons, in a long time, can not solve the core problem.

Even if there is no way to make a machine tool for cutting metal, some forward-looking research is still being done, and even in practical application, because of the large-scale use of wooden machinery in the Dinghai Navy, some woodworking machine tools have begun to appear.

In the middle, there are ordinary processing machine tools, of course, there is also a drilling machine, Zhao Xin's initial theory is from the top of the inflatable drill, with a drill bit similar to an inflatable drill, similar shape, with a master craftsman grinding out, and then fixed on a platform that can be rotated, as long as the wood is fixed, you can rotate, pull, to punch the wood.

In fact, it is still a little difficult to drill wood by manpower, and a variety of transmission devices are used here, so that the power of several people can be concentrated together to form the current punching method.

In the original carpentry, the method of punching is very difficult, sometimes, it is necessary to separate the holes, and it can not be very small, like now, from the thickness of the copper coin, to the thinnest only the thickness of chopsticks, what can be.

Wood is OK, iron is also OK, and under the premise that there is no problem with the cutter head and structure, power has become the biggest problem, and general manpower and animal power are not OK.

The hardness of steel is far above that of wood, not to mention, the new smoothbore gun uses steel with a hardness of 5.7 standard, which is harder and has higher requirements for power.

In the era when there was no drilling machine, the reliability of the barrel was very low, and the production efficiency was not high, which was recognized, of course, Zhao Xin could also use the previous method, that is, the volume method, which was in fact, before the large-scale emergence and popularization of the drilling machine, the common production method of the barrel of thermal weapons.

Ding Haijun is different from the smelting method before the Northern Song Dynasty, he used the smelting method of open hearth, as long as there is a suitable mold, the molten steel can be directly injected into these molds, the difficulty of producing flat steel, is not as great as imagined, and even the production of steel pipes is not impossible to produce.

However, the steel pipe is different from the gun barrel, which is a two-concept thing, especially the thinner the steel pipe, the more the mold can not be used, in the steel pipe, any blast hole, a bubble and the like, will affect the overall performance.

If you add the method of the steel hoop that Zhao Xin saw, and use the method of external afterburner to improve the strength of the barrel, the unsatisfactory barrel that can be made is compared with the master's construction, the service life, and the accuracy of the range, there is a big gap.

If it is said that the Dinghai Navy did not have a longbow as a weapon, based on the weapons situation in the middle and late Ming Dynasty, it may be really produced head-on.

Muskets, especially relatively inexpensive muskets, once popularized on a large scale, brought a huge effect, but it still could not be compared with the longbow.

Zhao Xin saw a very good smoothbore gun, such a firearm, placed at the end of the 19th century, will not be outdated at all, but he was born in the Dinghai Navy, and he was still a little out of time.

No science and technology appear casually, science and technology have accidents, many outstanding inventions, at the beginning, often for another purpose.

For example, Bailang Duoxi is a dye, not a later sulfonamide, such as the famous, fearsome sarin, which was a by-product of a highly effective insecticide in the beginning.

In fact, in the field of pesticides and insecticides, such chemically lethal weapons are often born by chance, and their appearance, many times, is just accidental.

But by chance, there is also inevitability, in the era of alchemy, even if it is made of sarin, what about it, except for poisoning the alchemist, there is no other effect.

The same is true of Bailang Duoxi, which is a dye, and the scientist who discovered his effect is only a scientist who studies streptococcus, and his youngest daughter was infected with streptococcus because of acupuncture, and at that time, in the whole world, there was no drug that had a therapeutic effect on streptococcal infection.

In desperation, the scientist injected his youngest daughter with a large amount of Bailang Duoxi, but unexpectedly, he was successfully cured.

Bailang Duo Xi also became a miracle medicine at that time, and even because of taking it, his whole body was dyed red, and he did not hesitate to do it.

However, if there are not sufficient research conditions, if it is not for the large-scale application of these accidental inventions, these accidents are just accidents.

Zhao Xin's crossing was an accident, the longbow was also an accident, and so was the smoothbore gun, the difference is that there are no conditions for the large-scale use of smoothbore guns now.

Longbow has no problem in this regard, although China did not give birth to longbow, but in the Northern Song Dynasty, the appearance of longbow is suitable, longbow is very simple, China also has a large number of materials for making longbows, but if there is no Northern Song Dynasty accumulated many years of knowledge of bows and arrows, to make it, it is very easy, but from ordinary longbows, change to real war bows, this development takes time.

It must be explored step by step, and the longbow must be gradually applied to the war, and unfortunately, in the early days of his birth, there is any cognitive deviation, and this weapon will not come out.

Because of the simplicity of the longbow, Zhao Xin even has reason to believe that the longbow appeared in the early days of China, but when he appeared, it was only simple wood, not more elastic wood.

The longbow, which should be the simplest bow, uses a branch and a vine with good toughness, and after being tied, it is an early bow.

Primitive people originally took such weapons and began hunting, and later, perhaps using materials such as animal tendons, made it more and more powerful.

In ancient China, instead of climbing on such a scientific and technological tree as the longbow, under the combination of various theories, they embarked on another path, the recurve bow and the short bow, because of their strength, but restricted the continued development of the longbow.

Even the whole concept is different, if there is no such a traverser as Zhao Xin, without him to understand the development of Europe and Britain in later generations, he brought the mature longbow to the Northern Song Dynasty, which is also perfectly suitable for the development of the Northern Song Dynasty, making the longbow the most important weapon.

In this sense, it is not an exaggeration to call Zhao Xin the father of the longbow, but Zhao Xin put forward the basic theory of the longbow and also produced a terrible killing weapon such as the triangular arrow, but he did not promote the development of the longbow, but it was a super archer like Sun Ji, and the Privy Council specially studied it and proposed more improvement methods.

The replacement of the original trees with more elastic wood, or composite materials, was an aspect proposed by the Privy Council, and even a certain amount of research was carried out to produce composite on the basis of the original short bow.

Of course, Zhao Xin knew that such research was wrong, and that if something entered the compound realm, his cost would definitely surge, and it would lose the universality of the longbow.

Ordinary wood, his elasticity, is definitely not as good as the composite materials treated with a variety of materials, because of such a foundation, the Northern Song Dynasty has accumulated a lot of experience in the short bow and composite bow, applied to the longbow, the bow arm of the longbow in the future, will be stronger, but this will be less numerical advantage.

If it takes three years to make a bow arm, the cost of this longbow will definitely surge, which in fact, has deviated from the path of the longbow guided by Zhao Xin.

But Zhao Xin couldn't stop the Privy Council of the Northern Song Dynasty, and even the research of the Ding Navy was not organized, he knew very well that the longbow was not the direction of the future, but he couldn't change it, the longbow was the most important and the most important weapon in the Ding Navy and even the entire Northern Song Dynasty, and a little improvement in the performance of this weapon was enough to change the combat strength of the entire Ding Navy.
