In fact, the hydraulic boring machine in this world, like the steam engine, is also a prototype item that has been used for a long time, and has even been used in the production of firearms. Back then, when human beings were not enough in magical achievements, the early days of the Rise War relied on bronze artillery to make up for their shortcomings and shortcomings in long-range firepower.

However, the barrel is fundamentally different from the barrel, the barrel wall can only be so thick, it must be accurate to a few tenths of a millimeter, or even lower. The barrel is completely different, and millimeter errors like bronze guns are even acceptable, because one of the most important points is that the barrel can also be remedied.

For example, in the feudal period, if there was a large error in the barrel, it would be thickened, or it would be manually polished after boring the prototype. Even some of the labor-saving ones can also play a strengthening role in putting a few turns of steel bars on the periphery of the barrel to prevent the barrel from exploding.

But the barrel of these remedies can not be used, once there is an error tube wall is too thin, it is impossible to use anything thickening to solve the problem, originally the front-loading smoothbore musket in the face of this world's magic and other races talent long-range attack, there is no advantage, if it is still dozens of pounds, it is really not as good as a burning stick, the burden on the soldier will be amazing.

There is really a negative example of this situation in the Middle Ages, that is, at the end of the Ming Dynasty in the same period of the Middle Ages, all kinds of firearms were shoddy, and then in order to prevent the explosion from being infinitely thickened, in the end, even the soldiers gave up the firearm attack, and there was also an embarrassing scene that the firearm could not beat the Manchu cavalry, and the ending is also conceivable.

As a reborn through time, learning from history is a basic operation, and this shoddy musket Duke will naturally not be used, so you can only start from the boring machine to see if you can come up with any ways to improve it.

"Bruru, I'll go with you to the hydroelectric plant to see what the situation is. ”

In the end, Duke decided to go to the hydroelectric factory first, although he was not very familiar with hydraulic machinery, but he had some experience in later generations, and maybe he could find a solution.

When they arrived at the hydraulic factory, Copperbeard and several blacksmiths were already waiting in the hydraulic machinery laboratory, but in addition to the participants of the participants, there were many blacksmith skilled workers who came to welcome Duke after seeing the movement.

Because Duke gave these blacksmiths the highest courtesy and treatment, if Storm Castle used to be the world of knights and nobles, civilian craftsmen had a natural disadvantage in status. Now it has completely changed, the priority of Storm Castle will always be the researchers of each laboratory, followed by all kinds of craftsmen, as long as there are powerful technicians, even Duke is polite when speaking, which is completely different from the previous noble lords.

Respect for science and technicians has become the credo of Stormcastle.

Duke made them feel respected, and naturally Duke earned the respect of the workers who came to the hydroelectric plant. Moreover, Duke has not been to the hydroelectric factory for a while because he has been busy with other things and dealing with the attack of the Holy See army recently, and many people have been looking forward to it for a long time.

In the face of the warm welcome of these craftsmen, Duke naturally waved his hand very cooperatively, and even walked over to "cordially condole" the technicians, which is a means and routine that must be possessed as a superior, and it is very important to win people's hearts no matter what era it is.

In the crowd, Duke also saw Nicole and Rose and several little witches, who were also waving to him enthusiastically. After a while, the mental outlook of these little witches has changed a lot, at least they are no longer afraid of facing the crowd.

I remember that when these little witches first came to Stormcastle, they were afraid of facing strangers, and even in the relatively closed environment of the hydroelectric factory, they rarely left the blast furnace room, let alone waved and cheered in the crowd like this.

With so many people, Duke couldn't say anything, so he could only smile and nod at them.

"Sister Rose, the lord smiled at us, he didn't forget us. ”

"It's only been a long time, how can the lord forget us. ”

"But he hasn't spoken to us in a long time. ”

Hearing Nicole's words, Rose couldn't help but laugh and replied, "Lord Lord, how can you have free time to chat with us with so many things." As long as we do our job well, it will naturally be seen by the lord. ”

"Hmm. Nicole nodded heavily, she wanted Duke to feel worth and repay Stormcastle for taking care of the witches.

The condolence image project was almost done, and Duke quickened his pace and walked towards the hydraulic machinery laboratory, after all, he came to solve the problem today, not to comfort the masses.

In the laboratory, Copperbeard and a few dwarven craftsmen were already waiting for Duke, and even Martin, the old musketeer, was involved in the development of the barrel as a technician.

Seeing Duke come in, the faces of the Copperbeards were full of guilt, after all, their own research and development failed, and the lord had to clean up the mess.

Seeing the expressions on the faces of several of them, Duke comforted with a smile on his face: "What kind of expression do you have, isn't it just a failure, on the road of science and technology, failure is a very normal thing, but success is full of luck and suddenness." So you don't need to be afraid of failure, and you don't have to feel guilty about me, you've done enough. ”

"Now it's time to get down to business, you guys bored a barrel and show me what's going on. ”

"Yes, my lord. ”

Duke didn't give an order, and saw Martin, the musketeer, take out a solid iron rod with a diameter of about three or four centimeters from the material next to him, and then walked to the hydraulic boring machine. As the sluice gate is opened, the hydraulic force pushes the runner below, and then the force is transmitted through the crank shaft, which finally drives the boring head to start rotating.

The solid iron rod is held in place by the clamp and pushed little by little towards the boring head, and under the rotational force of the boring head, the iron filings begin to fall. The copper whisker picks up the water scoop and keeps watering to cool the boring head.

The start was smooth, and you can see that the hydraulic output is smooth and the iron rod is moving forward in a straight state. However, when the boring is one-third, the speed of the turning head can be significantly reduced, and the iron rod is no longer moving at a uniform speed, and it needs to be artificially controlled at an angle.

Halfway through, the hydraulic boring machine has begun to shake slightly due to the lack of torque. The precision defect caused by this jitter was fatal, and even if the musketeer Martin tried to adjust the angle, the barrel could not be stabilized, and finally the boring error broke through the barrel, and the barrel was completely scrapped.
