Chapter 157 Machine Tools

"Squeak-" Craftsman Qian fifteen blew the whistle fiercely, his dark face tightened, as if he was facing thousands of troops and horses in front of him.

The four apprentice blacksmiths, who were naked in their upper bodies, quickly bowed down, carried the freshly cast bronze cannons with poles, and walked with small steps towards a long stone-faced platform not far away. The barrel of the cannon has not yet completely cooled, and the iron chains that pass through the front and rear lugs are steaming. The four apprentices were also sweating profusely. But everyone didn't dare to wipe it with their hands free, lest they be distracted and let the cannon tilt and touch themselves or their companions.

If you do, you have to lose at least half your life. The weight of the copper cannon is not large, only more than 530 catties, even if it is completely pressed on a person, it may not be able to crush him to death. But the temperature of the copper cannon is so high that it is frightening, and it is a burnt smell when you rub it casually, if you accidentally touch a sturdy, a small life will be announced, even if it is a fairy, it can't be saved.

In the last month alone, six apprentices were burned to death because they were distracted while working, and three others did not die on the spot, and are still lying alive in the medical hall run by the Semu people. However, there was still an endless stream of people who came to apply for apprenticeships in the workshop. Without him, the apprentice here not only manages the food, but also pays the salary. At the end of the two-year apprenticeship, you can get a regular job. If you accidentally smoke from the ancestral tomb and are exceptionally promoted to a craftsman or even a master craftsman, you will not have to worry about food and clothing for a few lifetimes.

Although he is not free to move after becoming a craftsman, you look at the losers in Huai'an City who spend the most money, how many men are not relying on being craftsmen? Even the three aunts and six mothers-in-law in Huai'an City all regarded the craftsman as the choice to choose a son-in-law. also summed up a few conditions that are most tempting to women, "First, make more money." Second, there is a workshop to manage food and clothing, and there is little spending. Thirdly, every day is either the day shift or the night shift, and they are as busy as a spinning top, so there is absolutely no need to worry about them going out to the casinos and kilns"

"Squeak-squeak-!" Qian Fifteen's whistle sounded again, and he ordered the apprentice to stop. stepped forward and rubbed his fingers on the pig iron track on the countertop, and he ordered loudly, "Lao Liu, is the pulley wiped well, get on the pulley, hurry up!" ”

"Coming, coming, coming!" An old craftsman with a beard commanded two apprentices to put an iron block with four wheels underneath on the tracks, "Wipe it three times to make sure it was clean enough to slip flies!" ”

"You talk a lot!" Qian 15 counted a sentence unhappily, and then quickly turned his head to the apprentices who were raising the cannon, "Hurry up and put the cannon in the pulley, quick." Zhao Da Zhao Er, the two of you fix the cannon ears in front. Zhang 5, Xu 6, the two of you fix the rear ear. Lao Liu, you take two apprentices to be responsible for leveling the body. ”

Six apprentices, a master craftsman, under his command, quickly put the copper cannon into the iron pulley, and tied it firmly with the chain through the cannon lug and the keyhole in the pulley. The pre-made triangular spacer was carefully tucked into the contact between the nose of the gun and the pulley, the muzzle of the gun was raised and stabilized in a straight line, and the barrel was aligned in a straight line with the grinding stone at the end of the track. Craftsman Lao Liu made another visual inspection and was sure that the barrel was completely level. Take a deep breath and stuff a large ball of mud into the gap between the pulley and the artillery.

"Shh The cement was scalded to the point of white smoke, and the smell of animal urine filled the air, irritating people's eyes. The craftsman Qian Fifteen, the craftsman Liu Laoshi, and the apprentices, but no one cared about rubbing their eyes. Keep your eyes fixed on the grinding stone at the end of the track.

The front end of the grinding stone is oval, with a maximum diameter equal to that of the breech. The second half of the grinding stone is ** on a thick and straight iron rod. The iron rod was about six feet long, and the end of the rod was forged together with a thicker iron rod. The thicker iron rod passed through a few fine iron supports and a thin wall to the outside of the shed, the large two-story waterwheel.

"Squeak!" Qian Fifteen's whistle sounded again. Everyone used their arms at the same time, pushing the pulley slowly towards the grinding stone. The muzzle of the gun is close to the millstone, close, a little close. Suddenly, there was a harsh grinding sound, causing everyone to tumble up and down. Golden sparks erupted from the muzzle of the cannon, dazzling.

"Squeak-squeak-squeak-" Qian Fifteen's whistle changed tone, short and agitated. One craftsman, one craftsman, six apprentices. Immediately following the rhythm of the whistle, continue to push the artillery forward, forward, forward. Concentrate and keep your eyes peeled.

Sweat flowed like a river over everyone's bronzed skin, illuminated by sparks, giving off a seductive hue. The shoes under his feet were soon wet, and the slate floor began to slip. But they did not dare to pause, did not dare to bow their heads, and continued to push the block forward with all their strength, and their angular faces were full of the peculiar piety of the creators.

"Boom!" The muzzle of the gun touched the baffle at the end of the tracks, and there was a sound of emptiness. Qian Fifteen's face was happy, and he quickly turned the whistle around and blew it from the other end, "Shh-shhh

The crowd followed the whistle and began to push the iron cart back in great stride. The red star was still emerging from the muzzle, but it was much dimmer than before. Suddenly, the muzzle of the cannon lit up again, and a golden river burst out, and then, the contact between the cannon body and the grinding stone was completely detached, and under the action of inertia, the position from which it came quickly slipped away.

"Lao Liu, test the barrel of the cannon. Zhang 5 and Xu 6 went to water the grinding stone and checked the grinding stone by the way. Zhao Da and Zhao Er, go and prepare the chisel. ”

"Yes!" The craftsmen and apprentices breathed a sigh of relief and trotted on to the next link. Soon, Liu Laoshi took a large wax of butter and returned with a cross made of wood. First, he held a candle and shone it into the muzzle of the gun several times. Then he slowly rotated the wooden cross and leaned in, and as he probed, he reported loudly, "The surface is smooth!" The burr was not felt in the anterior probe. There are no burrs in the middle section, and there are two, three, and four protrusions in the last section, and the last section near the tail of the gun. It is not clear from the muzzle of the gun, and it needs to be taken to the outside to be polished by hand. ”

"Okay, Zhao Da, Zhao Er, mark the barrel with the number of our group! Send it to the next shed. Lao Liu, you take someone to continue to clean up the pulley! Zhang Wu, Xu Liu, the two of you go to the last shed to take a look, when will their next round of gun barrels be cast? Qian 15 continued to command loudly while holding a pen and writing in a notebook.

"Yes!" The apprentices happily agreed, engraved the words "No. 2 shed, fifteen, money" on the tail of the gun, and then unloaded the barrel from the pulley, loaded it into a trolley, and sent it to the next shed. Craftsman Liu Laoshi handed over the matter of cleaning the block to the apprentice, looked around, quietly approached the craftsman Qian Fifteen, and asked in a very small voice, "Qian Smith, you said, at the end of this month, how much bonus can we get!" ”

"Bonus, bonus, bonus, bonus, you're big!" Craftsman Qian 15 smashed the account book in his hand on his head, and said loudly, "I said Lao Liu, can you think more about serious things?" This month, our group has been returned with three cannon barrels, and if there is one more, my grandmother's will have to be demoted to an ordinary craftsman, and your old Liu will have to be an apprentice again. Going to be an apprentice at such an age, don't you feel panicked! ”

"Well, isn't that because of the night shift, no, not used to it?" Craftsman Lao Liu flashed two steps, rubbed his smashed red head and whispered a defense. "Besides, although three of our guns have been returned, we have made seven more than others. Don't count the three reworked, but four more! ”

"My Uncle Liu, how many times have I told you, the account can't be calculated like this!" Qian Fifteen's eyes were so angry that his eyes darkened, patted his head hard, and begged loudly, "Make a few more, just make a few more barrels." But if you blow up the chamber during the test of the gun, you will not only smash the rice bowl of our group, but also the people who built the guns in the previous class and those who are in charge of manual grinding in the next class. When the time comes, even if I don't trouble you, they will have to find you! ”

"They dare, the bald king of the third shed, when he first entered the workshop for the exam, I recruited him. By seniority, he has to call me Master! Liu Laoshi glared at him, seven dissatisfied, and eight were angry. But soon, like a deflated toad, he softened. He looked around again, and asked in a lower voice, "I said money maker, money craftsman, Huang Lao crooked he won't really be ruthless." We were the first to follow him! ”

"The key is that this batch recruited by Huai'an is easier to use than us!" Qian 15 glanced at him and sighed helplessly, "You used to be a hoe, and I followed my father to make door knockers, beast heads, and locks." We're not very crafty. And on the Huai'an side, they either make hairpins and flowers, or they make gold chains, silver bracelets, and copper mirrors. The worst of them are also made of wine jugs, silver cups and bronze night jugs. The work under the hand, that is called a fine. Then use these water hammers, rhinestones, and horizontal and vertical grinders made by our Dudu and Jiao Dajiang, think about it, can the things made be bad? ”

"Then, then let's let the people who come after us climb their heads!" Liu honestly sighed and muttered in protest.

"If you don't want others to climb on top of your head, let's work harder!" Qian 15 knocked him with the ledger again, and reprimanded him in a low voice, "Usually work hard." After work, don't keep thinking about messing around. Hurry up and recuperate and wait for the next shift. We are all the fairest, as long as you work under your hands, he will never treat you badly. Ah, the Governor. The Governor has come to see us again. Quickly stood up for me and wiped my face clean. The Governor is coming to us, and he's coming right away! ”

Note: At least during the Tang Dynasty, Chinese craftsmen had begun to manipulate all types of primitive lathes. In the Ming Dynasty, there were monographs describing the structure and usage of grinding machines. It can be said that until the beginning of the Qing Dynasty, China's industrial exhibitions did not lag behind the world too much. And then
