With Gu Yi's current ability, it is already the limit to be able to do this, and he can only hope that the iron used to make steel, which naturally contains these metal elements, can barely be used.

Fortunately, it is impossible to make the saw blades in Gu Yi's impression, but in any case, the saw blades made of these steel ingots are much stronger than the "wolf tooth sword" originally used by the craftsmen, right?

Even if the quality is poor, at most it is almost the service life, and it is not as easy to use as a high-speed front hacksaw blade, which he produces and sells himself, and does not need any cost, it is nothing more than to make more, and replace it if it is broken.

It is definitely not possible to use low carbon steel directly to make saw blades, Gu Yi can only use his pitiful little common sense theoretical knowledge, blindly instructing the masters, to carry out a series of annealing, quenching, tempering, carburizing and other heat treatment processes.

Because he was a little worried, Gu Yi simply asked the masters to use the folding and forging method as much as possible, "one hundred refining" may not be, but dozens of refining do, after all, it is just to make a saw blade, not to make a magic weapon.

In the face of Gu Yi's guidance, several masters who were named to participate in the research were extremely cautious, not only according to Gu Yi's requirements, the entire saw blade was made only three or four millimeters thick, but the saw teeth were also processed into wedges, and a master craftsman personally polished the saw blade to be extremely smooth and shiny!

During the whole process, Gu Yi originally planned to recruit more blacksmiths to come over and watch, so as to prepare for the large-scale processing later, but I don't know what kind of madness these masters smoked, let alone call their disciples to learn, if someone around the processing site dared to approach, they would rush over with a sledgehammer in anger to chase and kill others, and even Ziyu and Huhu, who were curious and wanted to come and see, were driven out of the city for hundreds of meters!

After Gu Yi's permission, they humbled each other for a while, and a master craftsman who looked the oldest and estimated to have the best craftsmanship carefully engraved his own name on the end of this one-meter-long saw blade.

Then Gu Yi watched the master craftsman, picked up the saw blade that had been polished to the cold light, and heroically pulled a hole on his arm, drenched the saw blade with the blood spurted out of the "poof", and threw it into the furnace for the last temper!

Gu Yi swallowed his saliva, he had heard that there was a divine blade that wanted "blood sacrifice" or "blood refining", but this is a saw blade, what are you doing so desperately? If the trial is successful, let you fight one hundred and eighty pieces, and you must not be anemic?

In any case, after a lot of hardship, the saw blade was finally made, and the relieved Gu Yi summoned a carpenter to install a frame on the saw blade, that is, a "円" shaped wooden frame, one end of the hemp rope, the other end of the frame saw with the saw blade, and then let the carpenters try it.

Gu Yi led a group of [Iron Battalion] masters to mysteriously tinker for a week before they came up with this thing, not only the carpenters in Limin Village, but even the craftsmen of other types of work have heard some "rumors".

The two [Wood Battalion] masters were extremely cautious, and from the [Iron Battalion] master who almost sawed off his arm, they took over this [high-grade treasure] level saw made of [dark iron] with a whole body, looking at the momentum, Gu Yi estimated that if the conditions did not allow it, they would also burn incense and sacrifice like the blacksmiths before doing it.

The two masters carefully put this "magic saw", erected on a log that is enough to have a hug of thickness, the scene is full of people on the three outer three floors, all of them hold their breath and watch the two masters gently push and pull a few times, gradually increase the force and slowly increase the speed, with the sound of "swish", the saw blade quickly fell into the log, the tender yellow saw foam accompanied by a fragrance of trees, snowflakes drifted out!

Although they were holding their breath and pulling the saw, it was obvious that the expressions of the two masters were getting more and more excited, and their emotions were becoming more and more excited, and the speed of the "swish" was about to catch up with the mechanical drive, and Gu Yi was a little worried that they would accidentally use their strength to pull off the saw blade that was finally made.

I don't know if the quality of the saw blade is hard enough, or the craftsmanship of the two masters is excellent, but after more than a dozen breaths, I heard a slight "click" sound, and a piece of log that was sawn off fell down, and the two masters seemed to have exhausted their whole body strength, and at the same time collapsed on the ground with tears in their eyes, and they all dragged the big saw to death and did not let go, and the crowd of onlookers suddenly burst into a burst of cheers and tsunamis, and they didn't understand what they were happy about.

Without waiting for Gu Yi to react, several figures rushed out of the crowd, regardless of the desperate obstruction of the two masters, they snatched the big saw directly from their hands, almost causing a riot among the carpenters and blacksmiths.

Surprisingly, the first to grab the big saw was not Amber Tiger or those black-armored guards who looked very strong, but Ziyu, who seemed to be weak, he carefully stroked the saw blade for a while with a surprised face, and only came to his senses for a while, smiled at the Amber Tiger who was eyeing him next to him, and quickly left after handing over the big saw to him.

And Amber Tiger also touched the big saw for a while, tried the blade with his fingers and stretched out his fingers, listening to the pleasant buzzing sound and sighed: "It's a pity!

As he spoke, he looked at Gu Yi with surprised eyes, shook his head and returned the "magic saw" to the masters who couldn't bear it anymore and began to move, opened his mouth, as if he wanted to say something to Gu Yi, but in the end he couldn't speak, and walked away in frustration.

Gu Yi looked at the two groups of people with different expressions, smiled, didn't care about them, and directly gathered the masters together, handed them a stack of drawings, and asked them to think about making the big saw, medium saw, small saw, hand saw, plate saw, and various saws he designed according to the specifications.

This time, Gu Yi couldn't let them play by themselves, not only forcibly ordered them to bring all the apprentices, but also formulated a strict assembly line process, according to their meticulous and slow work, the year of the monkey and the horse month can gather enough saws for work.

Moreover, in order to prevent them from being anemic, Gu Yi strictly forbade them to see their arms again, but allowed them to engrave the names of the saw blades they made.

Although several iron wrought masters were very disappointed that Gu Yi strictly forbade their blood sacrifice, they did not dare to disobey and took the entire [Iron Battalion] craftsmen under their command, and went triumphantly in the envious and hateful eyes of the craftsmen in other industries.

After tossing for so long, Gu Yi, who was about to go to the rest meeting and breathe a sigh of relief, inadvertently saw those [carpentry battalion] masters happily taking turns to try the "divine saw", suddenly fluttered, and after a while, he slapped his head, and hurriedly went to the blacksmiths.

He found himself making a common-sense mistake, just thinking about making regular saw blades, but forgetting that this kind of saw was okay for carpentry, and it was useless to process large boards, and the logs they cut down were all big guys!

Besides, even if it can be used, manual sawing is slow and laborious, and he should have made a "disc saw lathe" from the beginning!

After telling the blacksmiths to study and study how to make saucer-shaped saws of different sizes according to his requirements, Gu Yi suddenly remembered that the water-driven disc sawing lathe he originally expected seemed to be a little difficult, and the water volume of the [Trap River] was quite good, and it could be used after connecting the water wheel, but it was impossible to carry the logs from the front mountain to the back mountain, and then hang down from the cliff nearly 100 meters high, and then transport it back to the front mountain after sawing, right?

There is a water source in the front mountain, but it is just a small river flowing down from the mountain, both the water volume and the flow rate can not meet the requirements, unless you go to a distant place to find a suitable water source, otherwise you can't use the hydraulic disc saw lathe!

This made Gu Yi scratch his head for a while, and he could only think about it with a sad face for several days, trying to recall what skills could come in handy in the information recorded in the "Goldfinger Usage Guide", and he hated himself for being Mao back then, not a technical house, but a novel house.

After racking his brains and almost scratching himself bald, Gu Yi finally found a roughly feasible method, and after several days of writing and drawing, he designed a geared and chain-driven turn-sawing lathe composed of two rows of winch devices similar to exercise bikes.

But when Gu Yi went to the blacksmiths with a thick pile of fool-like design drawings drawn, he stumped the craftsmen who were about to catch up with the eighth-level fitters in Gu Yi's opinion.

The problem is that the chain that Gu Yi wants, even if it is not as fine as a bicycle chain, it is difficult to combine so many fine parts together without falling apart, and it can accurately fit with the winch gear without making mistakes!

Gu Yi, who was about to vomit blood by himself, could only swallow back a mouthful of old blood, and let the masters help find a way to solve the problem.
