Daqin Fusu: It is difficult to start the battle

Chapter 66 Hydraulic Sawmills

Li Shang opened his eyes wide and murmured, "Is it so magical?"

"Using a sentence that my father often said, it's so ingenious!" Gong Shupan finished with a smile, and continued to introduce.

"The structure of these two sawmills is not complicated. In His Majesty's words, the circular motion of the water wheel is converted into a reciprocating motion through the crankshaft, which drives the saw blade to pull back and forth to achieve the purpose of sawing wood."

Li Shang took a closer look and found that the saw blades were all made of steel. On the top of the saw blades, there was a line of small characters engraved, "In the first year of the second generation, he will be the Shaofu rail, Gongshi Li, Chengyu, Gongchang"...

Li Shang nodded slightly. This is Daqin's Wule work name system. If there is something wrong with this saw blade, you can ask the blame all the way to the point where you will be sent to Shaofu Gong!
Gong Shupan said: "These two saw blades are all long saw blades of the same specification. In His Majesty's original design, he originally intended to use circular saw blades, but after the trial, he found that the saw blades vibrated and could not cut out smooth wood. After the second revision, it was decided to use a saw blade that moves up and down."

"We raised the embankment by the river and built two waterwheels, each of which can drive two sawmills."

"The two sawing machines in this shed are specially used for sawing boards."

Gong Shupan took Li Shang to the side, pointing to the vertical tool holders installed on both sides of the main shaft of the waterwheel: "The frame-shaped tool holder can install a large row of saw blades vertically, and can also be adjusted according to the thickness of the required wood. Saw blade spacing."

"This is the linkage device when sawing wood. The saw blades are divided into two groups. One group goes up and the other goes down. As long as the log is pushed into the knife holder, the plank will come out from the other side. It is very labor-saving and only needs two or three people to go inside. Just send the wood."

Gong Shupan pointed to the platform opposite the knife rest and said, "This is what His Majesty calls a sawing machine. There are four iron wheels on the bottom, buckled on two wooden rails, and can move forward and backward."

Li Shang looked it up and down and said, "Can I try it later?"

Ziying said cheerfully: "Of course, it's a waste of labor, and of course I won't refuse!"

"Just before starting work, you need to wear special work clothes!"

Li Shang followed his fingers and saw the'work clothes' hanging on the wooden rack.

He recognized the pig's mouth structure, which is said to be used to prevent dust. As for the long and thick leather gauntlets, it should be used to prevent the arms from being sawed.

"Is it the same for the other two?" Li Shang touched the saw blade and turned to look at Gong Shupan.

Gong Shupan shook his head and replied: "The other waterwheel is connected to two single-saw saw tables, which are divided into upper and lower layers. The lower layer can be used to cut thick logs, and the upper layer can be used as a table saw." , make some special wooden strips or wooden squares, and you can also use a ruler to saw a shape that meets a specific angle."

"Is this how the door frame of the bamboo house was sawed out?" Seeing Gong Shupan nodding his head in acquiescence, Li Shang praised, "As expected of a descendant of Luban, this saw makes you understand!"

Gong Shupan smiled all over his face, cupped his hands and said: "This is all thanks to His Majesty, we are just making a slight profit or loss on this basis!"

Ziying waved his hand, and several slaves walked into the shed carrying the dried logs.

Gong Shupan directed Li Shang to stand behind the sawing machine to operate, turn the handwheel, and move the three pushers on the sawing machine to the inside, and said to the foreman on the side:

"Let them put the log on it, yes, pull it out from the front, and push it tight from the back!"

After the foreman led the slaves to move the logs according to his instructions, Gong Shupan walked over and smashed in the three iron wedges on the pusher.

Iron wedges inserted into the log like a bird's beak hold the log in place.

After Gong Shupan fixed the log, he went to the saw blade, opened the water tank above it, and put a bamboo pipe onto the saw blade, which was used to send water to the saw blade.

Then he checked whether the saw blade was fixed, finally nodded, and informed the engineer outside to connect the waterwheel.

Only the sound of rushing water could be heard outside, and the saw blade began to move up and down in an instant.

Gong Shupan warned: "Attention everyone, during the operation of the saw, you must not be approached by irrelevant people. Even the person who operates it should pay attention not to approach it within one foot of the saw cut, or you will die!"

Waiting for the foreman to finish translating his words, and after several slaves nodded, Gong Shupan returned to the sawing machine, looked forward along the edge of the log, and then said to Li Shang, "It's time to start."

Li Shang pushed it, and then said pleasantly, "It's so lightweight!"

Although the log required several slaves to carry it to the saw table, it took little effort for him to push the saw table.

Gong Shupan rolled his eyes at him, and said in his heart that you are a strong man who singles out predators, of course you feel relaxed!

Li Shang pushed forward two or three feet, and the front end of the wood had already touched the saw blade, and there was a series of 'creaking' sounds, and the saw blade moving up and down cut into the log.

Water flows down above the saw blade, washing away the sawdust and flowing into the trench dug in advance below.

Li Shang kept pushing the sawing machine forward, and there was a constant 'rustling' sound, and it seemed that he had almost reached the bottom of the wood.

While staring at Li Shang's movements, Gong Shupan ordered, "Quick! Catch the side boards that are about to be sawed off!"

After the foreman translated his words, four or five slaves hurried to the back of the saw to pick up the sawn side board.

Because it was wood that had not been barked, a small piece of bark was caught on the saw table by the saw blade at the end. It was not a serious problem at first, but a slave stretched out his hand to squeeze it off.

Gong Shupan hurriedly shouted, "Stop!"

Although the slave didn't understand, he was shocked and froze on the spot.

Foreman Luo Yue stepped forward, pulled him back, and then beat him with a whip.

There were many screams, but the Luoyue slaves standing in the same row turned a deaf ear to them, and instead showed gloating expressions on their faces.

"That's enough, that's enough...stop!" Ziying showed a look of unbearable expression, and spoke to stop it.

"Okay...here!" The foreman hurriedly stopped, bending over and saluting like Qin people.

Gong Shupan reaffirmed helplessly: "After the hydraulic saw is turned on, no one can stand in front of the saw, and keep a distance of at least one foot from the saw blade. Otherwise, this is the end. Raise your hands if you understand!"

After the foreman translated it, several slaves raised their hands to express their understanding.

Gong Shupan shook his head, and whispered to Li Shang: "Actually, I've warned them many times about what I said just now, but I can't remember it. Young Master won't let you beat me..."

Li Shang just smiled and didn't answer. He walked to the sawn board and looked at it for a while, and shouted: "It's so straight, there is no bend at all!"

After treating the wound of the Luoyue man who was beaten, Ziying said with a smile: "There is a track control below, so of course it won't bend!"
