Chapter 37 Feathered pattern of flower steel

The vice was bolted to the table, and Su You tried to pull the threaded rod, and the entry and exit were very smooth.

Seeing that Shi Tong also gave oil carefully, he couldn't help but praise: "Good craftsmanship!" ”

Shi Tong looked at his finished product and felt very satisfied: "With the Yungang coke graphite crucible, this thing can be cast directly, Yungang is really good steel, and it is extremely hard after quenching." ”

Su You sighed with emotion: "The cost of this piece of stubborn iron alone is very high. ”

Shi Tong said with a smile: "If you want to do a good job, you must first sharpen your tools, and the Shi family understands this truth." ”

Su You rubbed his little hands and was a little excited: "That's good!" Today I'm going to teach you how to forge feathers! Are the cloud iron sheets and cloud steel sheets ready? ”

Shi Communication was full of heart: "It's ready." ”

Yuntie is the wrought iron smelted by Yungang with low carbon content, while Yungang is stainless steel with high carbon content.

Su You then instructed Shi Tong to clean the surface of the iron sheet with hydrochloric acid, and then grind off the pickling layer, and a layer of steel and a layer of iron were overlapped.

The two ends were drenched with molten iron and died, and they began to be tempered, folded, and tempered again.

Before each folding, sprinkle a borax brush to remove oxidizing impurities to avoid ash inclusion.

Finally, after eight forgings, the iron pieces are fused into a single bar.

The iron bars are chiseled into equal squares with steel chisels, stacked together, and the sides are also poured with molten iron to weld to death, and then forged together again when they are red.

The iron is then re-burned red, split from it with a steel chisel, then put together, and forged again together to form a piece of iron.

The hardness of the tempered iron square is not large, and the iron square is sawed into pieces of iron with a hacksaw.

The thing was not big, but the effort was quite small, and Shi Tong was tired and sweating profusely.

Arranging, forging, folding, forging, slicing, assembling, forging again, splitting, assembling again, forging again, he didn't understand why this little master was doing so much tricks on this little piece of steel.

But after Su You asked him to polish the sides of a piece of iron, wash it with acid water, and the magical pattern was immediately revealed.

Shi Tong held the iron piece and his legs were weak, his body was completely out of his control, and he sat on the ground with his ass.

got up and said in a trembling voice: "Mr. Divine Skill, although Ou Ye's cadre is not an exaggeration!" ”

His hands trembled violently, for fear that he would not be able to hold it steadily, so he quickly put the iron piece on the table again and looked at it respectfully.

On the iron sheet, the high-carbon and low-carbon patterns are interlaced, and there is a distinct feather vein in the middle.

Then the pattern is centered on the feather vein, bends to the sides, diverges, and expands to form a beautiful pattern like a feather.

Such a beautiful metal pattern, completely immersed in the metal, this is a beautiful product that has never been seen before, and the shock brought to Shitong is really incomparable.

Su You took Shi Tong's hand: "Hurry up, this is the first step." What does it look like to outsiders! ”

Shi Tong's legs were still weak, and with the help of his hands, he supported the table before he climbed back into the chair and sat down: "Tai...... It's scary, it's ...... This is what I forged? ”

After saying that, "snap" gave himself a slap in the face, and muttered: "It's not a dream, I'm not dreaming......"

Su You looked at Shi Tong's actions and laughed: "The reason is actually very simple, you go back and knead the glutinous rice flour, dye it one ball, one ball is not dyed, steam it until it is half-cooked, and then fold and blend it according to the method I taught you, and you can get the glutinous rice pieces with feather patterns." ”

"Master leads you into the door, practice as an individual, and then you will use this method to combine the dough to your heart's content, and then experiment with Yuntie and Yungang. Blades arranged in various patterns can be obtained. ”

In fact, Su You still knows a lot about the ways and methods of arrangement, but in order to inspire Shi Tong, he didn't want to say it for the time being, so he just gave an example: "Take the feather pattern just now, if we staggered some triangles above and below the blank, so that the blank forms a broken line, and then straightens the blank again, what will it look like when it is cut?" ”

Shi Tong thought about the changes in the lines in the iron material, and pointed his hand on the feather vein, drawing an S-shape.

Su You said: "Clever! This will give you the feather pattern of wavy feathers! ”

Shi Tong immediately shouted: "Shi Laosan, Shi Laosan hurry up, according to what the master said, steam two half-cooked dumplings!" ”

After speaking, he said to Su You: "As soon as I think about it, it should indeed be so, that is, no one has tried such a complicated forging method before." ”

Su You commanded in an old-fashioned manner: "Isn't that the case, hurry up, choose a piece with the most beautiful pattern, cut out the blade pattern and paste it, and file the knife shape." ”

Shi Tong wanted to do it himself, but Su You pulled him again and said: "Don't worry, you have something else, first sheath these two pieces of boxwood and make a wax mold." ”

This stone is proficient, and at first glance he is a veteran of stealing bronze ware.

After that, a mixture of toner, calamine powder and copper powder is prepared, which is put into a graphite crucible, sealed with clay, heated with coke blast, and boiled copper juice.

The powder melted quickly, and it didn't take long for the pottery seal to be removed, the impurities were removed, and a pot of copper juice was obtained.

Shi Tong scooped a small spoonful of copper juice, poured it into the sand mold, and after a flame accompanied by the fragrance of wax rose, he opened the small sand box, and two golden copper pieces appeared in front of the two of them.

Shi Tong was shocked again: "This is ...... Is this the art of turning copper into alchemy? ”

Su You couldn't help but feel funny, and quipped: "That's so beautiful for you!" It's brass! ”

"There's something called lead, but it's not lead, it's another metal, zinc, which is the main component of calamine."

"When zinc is fused with copper, you get golden brass."

Shi Tong looked at the brass and sighed: "Pure copper is purple, this copper is really like gold......"

Su You smiled: "It's a lively look, I'm not familiar with the rest of the things, do you see the grooves on the top?" Fill it with silver to make it convex, and then carve out the petals of the flower vine, to be three-dimensional. These things are up to you. ”

Shi Tong turned out the burr of the small file to polish the brass casting: "That craft is called silver!" Look, Master, I promise to get it properly for my aunt and grandmother. By the way, Master, why does your folding knife have more parts than my father's? ”

Su You took an iron needle and pointed at the drawing and said: "Actually, it's not much - this is a reed, to ensure elasticity, you have to use soft steel; This is a tension spring, which is actually a switch; This is a lever-type back lock, which is actually a small steel bar. There is a brake groove on the blade head, which will be stuck on the bulge in front of the small steel bar when opened, and the knife can be used after it is locked. Finally, press down on the back of the handle, lift the front end of the back lock, and unlock the knife to retract it. ”

Shi Tong felt a little dizzy: "I can't understand ......"

Su You patted Shi Tong and said, "First make the parts according to the size, and after I put them together, you will understand." ”

Soon Shi Tong's apprentices cast all the parts, opened the holes, and Su You began to assemble the folding knife.

Instead of rivets that really kill the knife, they use a smaller wooden rod to facilitate disassembly and adjustment.

This thing is actually very simple, relying entirely on the ingenuity of the design of the cutter head part.

When retracting the knife, the steel bar used as a back lock should be pressed from the tail of the tool handle, and the small protrusion on the back lock should be loosened from the card slot of the blade, and the blade should be unlocked.

When the blade is retracted, the reed under the cutter head is compressed, creating stress and energy storage.

After the cutter is in place, the tension spring clip on the cutter head will be pushed into the brake pit on the cutter head by a small reed to lock the cutter and ensure safety.

Put away the knife, Su You pressed the tension spring on the knife head, the blade was re-unlocked, and the reed was ejected, and the round head of the blade was locked up in the slide, and then with a "click", the blade was locked again by the back lock after opening.

Shi Tongru got a treasure: "This ...... What kind of trick is this, Master quickly show me! ”

Su You put the knife away and threw it to him, Shi Tong took it, pressed the tension spring button, the knife popped out again, Shi Tong broke the blade and found that it was very stable.

The blade needs to be pressed down to allow the blade to be flexibly retracted, and finally a gentle "click" is heard, and the knife is re-locked in the handle.

Because the tool is not yet formally mounted, the mechanical movement of the entire head within the shank and how it interacts with other components can be clearly seen.

Shi Tongle played it several times without thinking, and couldn't help but admire: "Master, your mechanism design is so wonderful!" ”

Su You was secretly funny, just this thing, it was so wonderful.

Which secondary two teenager has not dreamed of a treasure knife, Su You has always liked this kind of fine handmade gadgets, and micro-technology folding knives have always been his dream.

But with his salary, he couldn't play such a high-end brand, so he had to download the schematic diagram of the deconstruction diagram of the local tyrants from all walks of life from the Internet, ran to the town where he was helping, and had two meals with the young man in the hardware factory, and then started work with great interest.

And then, of course, a shameful failure.
