After an hour, Yang Sichen and the big shots of the shipyard had lunch in the small courtyard where Wang Dahai lived. Yang Sichen left Wang Dahai and Yu Tun behind and gave them the blueprint of the Flying Scissors Sailboat. He and Zi Juan were assembling the model of the Flying Scissors Sailboat.
After two hours, Yang Sichen and Zi Juan had finished assembling the ship model. Wang Dahai and Yu Tun had also finished looking at the blueprints. When they looked at the ship model, their eyes sparkled as if they had found a treasure. Both of them were old pirates and knew ships very well.
"Uncle Wang, Uncle Yu, how fast do you think we can build the first ship?" Yang Sichen asked politely.”
Wang Dahai thought for a while and replied,""Probably two and a half months, mainly because the wood cutting is too troublesome.”
"I will think of a way to deal with the wood. The two of you should take out the size and quantity of the wood you need as soon as possible. Grandfather said that he hopes we can build a ship as soon as possible. Now that we are in a hurry, any problem that can be solved with money is not a problem.”
The two of them nodded in agreement and started to get busy in the house. Yang Sichen began to meditate and cultivate his internal energy.
After two hours, Wang Dahai and Yu Tun took out a rough estimate of the size and number of wooden planks required and showed it to Yang Sichen. "How much does it cost to process a piece of teak wood like this?" Yang Sichen asked after looking at it.”
"If we process it ourselves, including the wood, it's less than 150 wen," Yu Tun replied.”
"How about this? "Uncle Yu, go find Uncle Zhong now and ask him to go out with you. We'll ask other shipyards to process them. As long as they pass the inspection, we'll charge them 225 wen per piece. If there's no wood, we'll get them from our shipyard. We'll pay 60 wen per piece if they pass the inspection. Using the same method, 75% of the oak processing was also contracted out. Please put in more effort and strictly check. Our shipyard only processes ironwood and a small portion of oak. I think this will speed up the progress.”Yang Sichen thought for a while and quickly said.
"Don't worry, Young Master. I'll be careful." Yu Tun nodded.”After saying that, she went out to look for Xia Zhong.
After a while, Wang Dahai said,""In this case, the two ships will cost 80,000 to 96,000 taels of silver.”
"As long as it doesn't exceed 100,000 taels.”Yang Sichen paused for a moment before saying to Wang Dahai,""Uncle Wang, this ship can sail fast because of the high bow. Unlike other ships that are completely submerged in the water, the bow seems to slide along the water. The main beam and side walls of this ship are very strong, so they need especially strong wood. I think only ironwood is suitable. How much ironwood do you want to add?”
After a while, Wang Dahai said,""We need to add about six or seven ironwood.”
"How long will it take for us to process the wooden planks this time?" Yang Sichen asked again.”
" It'll take about ten days if it's fast," Wang Dahai replied." Thirteen days if it's slow."”
Just like that, Yang Sichen spent half an hour sorting out all the matters in the shipyard.
However, from the model to the real ship. There were still many things to do. Circular saws, pulleys, lathes, sewing machines... but it wasn't difficult to achieve these. Since they already had the power waterwheel, they could just modify the other machines.
8th century B.C. Wheels appeared in China, 5th century B.C. A 40-toothed bronze ratchets appeared in China. Not long after, the iron ratchets appeared. Before and after the Han Dynasty. China had steel processing technology that was accurate to the millimeter. If the craftsman was given enough time to grind it by hand. The accuracy could be further improved…it could even be said that…Yang Sichen only needed to come up with ideas and draft a sketch. The craftsmen could make it themselves. In any case, it was a machine tool used for wood processing. The requirements for strength and accuracy were very low.
Only the sewing machine was more complicated. Fortunately, he only used thick earth needles to sew the sails. The components could be made to be " stupid, big, thick, and black." Anyway, the simpler the structure, the better. As long as it could be used. The design of the pedal through the belt to transmit power to the body. The eccentric wheel was used to convert the rotating motion into a reciprocation motion. Thus, the needle could pierce up and down.
Yang Sichen drew the sketch of the sewing machine overnight and the detailed modifications to the other machines. Then, he sent the purple silk to Wang Dahai.
In the evening, Yu Tun brought back the exact news. The teak and oak boards needed for shipbuilding were all contracted out, and the price was lowered to 235 wen per piece.
Yang Sichen and Zi Juan were busy working until the wee hours of the morning when they finally rested in Wang Dahai's courtyard.
…………
Yang Sichen thought as he lay in bed,"Other than tools, the form of production organization is also an important factor in determining labor productivity." In the Qin Dynasty, the weapons manufacturing industry had already achieved assembly line operations. China's shipbuilding industry had already achieved specialization during the Three Kingdoms period when Sun Quan, the king of Wu, built the ship Chang 'an. But for some reason. Perhaps it was the devastation of war, or perhaps it was the loss of written records. The Yang Family's shipyard didn't have assembly lines. He had to discuss it with Wang Dahai tomorrow.
The next day, Yang Sichen and Wang Dahai decided to change the production method after a discussion. They hoped to achieve a streamlined production process. Take carpentry as an example. Wang Dahai would set a list of the required wood size. Then, according to this list, Yu Tun would be in charge of cutting the boards, Zhan Dafu would be in charge of rounding and drilling, and someone would be in charge of polishing and painting. Finally, Wang Dahai would be in charge of the final assembly and acceptance.
Everything was based on the list. If it could not be loaded onto the ship, it was because the size were wrong. If the measurements were correct, the responsibility lay with Wang Dahai.
With such a person in charge, not only could the person focus on one task to improve, but the responsibility could also be assigned to the person. Coupled with the reward and punishment system, the efficiency of shipbuilding would naturally be greatly improved.
In order to further increase efficiency, Yang Sichen designed a simple portal crane. It was a frame made of ironwood that spanned across the dock. It was 80 feet high and 120 feet wide at the bottom. Three pairs of wheels were installed on both sides of the bottom. Wooden tracks were laid on both sides of the dock so that the wheels could be stuck on the paved wooden tracks. The top was 60 feet wide, and there was a simple roller crane in the middle that could move left and right. With a person pulling the rope on both sides, it could lift more than 5,500 kilograms of wood. After fixing the rope and pushing the wheels on both sides, the wood could be transported to any position in the dock.
According to Wang Dahai's estimation, if the supply of wood could keep up with the construction period of the first Clipper Sailboat, it would only take 28 days. If two Clipper Sailboats were to be built at the same time, the construction period would only take 41 days!
In the modern shipyards of the 21st century, it would take at most seven days or less to make such a " small sampan " with ready-made materials. But in the 17th century, this speed was already very shocking. With the use of new production tools and assembly lines, the productivity had increased by more than three times!
