Looking at the atmospheric and practical carriage, Ji Xinyu couldn't wait to pull it out and try it, first ran on the official road, the shock absorption effect is quite good, there is almost no bump in jogging, and the bump feeling is also very light when running fast, which is completely acceptable. I walked around the cement floor connected to the cement workshop, and I didn't feel any bumps, and Ji Xinyu, who was satisfied, began to ask the blacksmiths to start making parts such as steel pipes and iron sheets for the carriage.

Taking advantage of the waiting time, Ji Xinyu and Aiden began to build two freight versions of the carriage, and the shock absorbers under the four carriages were removed from the outside of the car and replaced with a semi-suspended support frame, so that the shock absorption effect was much worse after loading the goods, but the number of loading was increased, and the arc steel plate and solid tires under the car body still had a lot of shock absorption effect. There are no seats in the carriage, and all the decorations have been removed, and it has become an empty box with a width of one meter eight and a length of two meters, so that the amount of goods that can be loaded has been greatly increased, and because of the relationship between the bearings, the horses can be pulled up with a lot less effort.

Ji Xinyu and Aiden made bearings and springs, and the blacksmiths made various other parts, and in just six days, the two freight carriages were completed, and Ji Xinyu had the freight carriages pulled onto the cement road and began to transport cement from the cement factory to Lingchuan Mansion.

After testing, the four-wheeled carriage can transport more than twice as much as the two-wheeled carriage, and pulling cement once can allow dozens of craftsmen in Lingchuan Prefecture to use it for a day, greatly reducing the time it takes workers to carry cement. I heard that two days later, He Xingwang arranged for someone to deliver soap to the Xue family firm, and Ji Xinyu asked them to use a four-wheeled carriage to test the actual performance of the four-wheeled carriage on the official road stone road.

Let the blacksmiths continue to make more than a dozen sets of various parts for backup, Ji Xinyu came to the field where the irrigation canal was being dug and took a look. Ji Xinyu arranged 60 people to take care of the 600 acres of land by the river, plus the original dozen people, each of whom had less than ten acres of land, and at the same time, most of the displaced people also helped dig irrigation canals here, hoping that they would open up wasteland as soon as possible, dig the irrigation canals, and plant rice, and the remaining displaced people were arranged to various places to help build roads and houses.

He Xingwangxing hurriedly walked over and reported: "Young master, I heard that there is an old Mr. Guo Yunshan in Wenchang County, a hundred miles to the south, who is an expert in water conservancy, and his ancestors once followed the water conservancy expert Wugu Sun Zexing in the previous dynasty to repair water conservancy projects in Danzhou and Yazhou. ”

"Shall we send someone to invite the old gentleman?" Ji Xinyu asked.

He Xingwang said embarrassedly: "We sent someone, but the old gentleman said that he was old and didn't want to leave his hometown. ”

"Then send someone to invite it, if it doesn't work, I'll invite it myself." Ji Xinyu knows the importance of water conservancy in this era, which is directly related to the question of whether the people can eat enough.

Walking to the waterwheel that has been made, watching the fast-rotating waterwheel drive the bucket to bring a large amount of water to the reservoir on the shore, the homeless people are busy but happy, but a few children are involved, and Ji Xinyu is worried.

The appearance of the homeless people made Ji Xinyu realize the danger of this world, the rampant cruelty of the pirates and pirates, and the cowardice and cowardice of the Zhongzhou army.

He thought of the little girl Kong Xiaoling, who almost starved to death, this 16-year-old girl, who was forced to leave her hometown with her 18-year-old brother because of the war, wandered around, and almost starved to death on the road.

The war took place on the opposite continent, only more than a hundred miles away from Qiongzhou Island, if Qiongzhou also suffered a pirate attack, would he be able to resist it? Thinking of this, Ji Xinyu's sense of crisis is getting stronger and stronger, and if he wants to protect himself and the people around him, he must develop as soon as possible.

Ji Xinyu originally wanted to teach Niu Gu and others mechanical information step by step, so they started with gears and bearings that were easy to accept, but now it seems that they have to speed up.

Turning around and going to the workshop to find Ushitani, he decided to make a manpower boring machine first in the absence of energy power, and began to find a way to speed up the production of guns, only in this way can he deal with the danger that will come at any time, and the sudden arrival of the enemy Lingchuan Mansion around him will not have the ability to protect himself at all.

Now there are bearings and gears, it is not difficult to make a boring machine, the manpower boring machine is the rotation force of the manpower rotation, through the gear set to change the speed transmitted to the boring bar, the boring bar is in the middle of the bearing, the stability of rotation can be guaranteed, the boring bar drives the front end tool to gradually rotate forward at high speed, you can gradually grind out the size of the accurate and smooth hole, so as to quickly complete the primary grinding of the barrel.

The boring cutter and boring bar are synthesized from various ores that Aiden has recently found over the mountains and mountains, and in Aiden's words, both the wear resistance, hardness and heat resistance are very good, and it is easy to deal with the current earth steel. This can be regarded as allowing Ji Xinyu to experience the convenience brought by a golden finger, and the most difficult grinding process of gun barrel processing is easily handled by the machine.

With Ushiya and a few blacksmiths, he was busy in the workshop for more than ten days, and finally made the world's first boring machine. Then, using gears and couplings, a linkage device was made between the boring bar holder and the gun bar holder of the boring machine. At the same time as rotating the boring bar, the gun holder holder moves forward to the boring bar at a constant speed, so that the required gun bar can be ground out as long as it is one or two times, and then the grinding head can be completely smooth after fine grinding, and a qualified gun bar can be completed.

Then Ji Xinyu tried to use a boring machine to draw rifling, but found that it was very troublesome to use a boring machine to draw rifling, and Ji Xinyu had to find a way to make a rifling machine with Aiden.

The working principle is similar to that of a boring machine, except that instead of rotating at high speed, it is required to reciprocate at a constant speed. Add a lever on the manpower runner to drive the boring bar located on the track to reciprocate along the track back and forth, and the rotation of the boring bar is controlled by the gear and the rack connected next to it, and the rack is connected to the control angle arc card groove above the rack.

On the other side of the gear, a boring bar with a diameter smaller than the barrel is driven, and the boring bar passes through the barrel fixing frame, and there is a card slot at the top of the boring bar, in which boring tools of different sizes can be placed. By turning the wheel by manpower, the metal bar can be moved back and forth, and rotated at equal distances under the action of the gear, so that a threaded rifling can be drawn inside the barrel.

A pusher connected to the gear part is installed on the side of the barrel fixing frame, and the pusher pushes the one-way gear with reference to the revolver structure, and each time the push rotates to fix the equidistance, the boring bar in the steel pipe drives the boring cutter to rotate, and the spiral rifling is drawn out one by one, and the depth increases little by little until the depth reaches the standard. By adjusting the height of the rack by controlling the angled arc slot, it is possible to pull out an unequal number of equidistant rifling in the barrel.

The structure of the rifling machine is not complicated, but it requires more parts. Niu Gu didn't have time to carefully test the boring machine and began to build the mold, plus the jade craftsman next to him cooperated with the polishing accuracy, Ji Xinyu asked Aiden to secretly fine-tune the precision devices, and he was busy for five whole days, and finally made the rifling machine.

Looking at the two machines, Ji Xinyu believes that they are the first people to batch process gun barrels in this era, and at the same time, they also have confidence in the mass production of guns.

Under the power of the Aiden brand knives, a barrel can be processed in only 20 minutes, which also includes the time to change the tool.

Then began to test the rifling machine, Niu Gu and the others didn't know why they wanted to pull out scratches in the barrel, they just listened to what Ji Xinyu said and they did it. Ji Xinyu adjusted the distance of the barrel and the rifling angle to make people start to rotate the wheel, this time Ji Xinyu set up six equidistant rifling, this is the best plan for Aiden to calculate the current barrel is more labor-saving and can enhance the power.

The barrel changed six angles in a loop with the rotation of the runner, and it took only 30 minutes to make the six rifling wires, but even then Aiden felt slow, and in his opinion that if there was good material, it could be formed in one go.
