"Teacher, is there any more advanced alloy formula? It is high temperature resistant, corrosion resistant, has high hardness, and is also flexible?"
Bolu's needle-in-a-haystack metal formula plan has yet to produce suitable results, but the need is urgent, so he decisively chose to seek help.
"Yes, you can just add a little fine gold." Landau replied casually without stopping his work.
"A cure-all?"
"The universal elixir!"
"So powerful? But at what cost!"
"Expensive, 100 kilograms is equivalent to 1 gram. The more, the more powerful it is."
"...How much is a hundred kilograms of iron? Isn't this cannon worth several kilograms? Is there a formula that is not so extravagant?"
Polu felt like he was punched in the face.
"Then I'm afraid you are overthinking. How can there be such a good thing in the world? How can you get good products without spending money? This is a recipe for making weapons and armor. In the past, everyone thought it was acceptable, but you have to use this thing
Are you afraid that you have lost your ambition in making cannons?"
Landau showed a look of disdain, as if to say who asked you to set such high standards.
"Here, some commonly used formulas for high-end alloys." He wrote something on a scrap of paper and threw it to Bolu.
Bolu took it and took a look. The formula metals for various large shields were of a slightly lower grade this time, but they still couldn't be used.
A pain called poverty stung him deeply.
"Also, are there any lower-end ones?" Polu, who could only choose the basic model, felt that he couldn't hold his head high.
"No, low-energy-level iron alloys cannot guide magic and are of little use. Wait, let me think about it. It seems that there are records in the literature that low-energy-level iron alloys have been used in some components. Let me look for it." Landau wrinkled
He frowned, as if he was recalling something.
He turned around, rummaged through the bookcase, and found out a book that looked quite historical: "Ha! Found it! Let me take a look. Well, adding this, adding this, you can get a certain degree of high temperature resistance and
You can give it a try for its wear resistance. This alloy was used in the mage tower structure hundreds of years ago. It should meet your needs."
"Hundreds of years ago? Well...don't they use this now?" Polu couldn't suppress his curiosity.
"The mages have stopped building mage towers on the island a long time ago. It's a waste of materials. The entire island is just a giant magic circle."
"...Okay, then I'll go to work first."
Soon, materials were found in the foundry workshop, and Bolu's head hurt when he conducted the first experiment: "This is also called a low-energy alloy? I can't even shape it! How can I process this thing! Just
Can it be played by high-end players? How awesome are high-level alloys? I’d better save this for turning tools!”
Forced to adjust the content, Bolu produced a large array of samples with various contents. Fortunately, Tris also compiled a large amount of metal properties information and collected many other metal elements precipitated from steel.
So after several experiments, we successfully obtained an alloy that added two metal components and had good overall properties.
"Tris, record the composition of this steel and try to find a better way to heat treat it. It's called T1 alloy."
With the help of this new material, Polu successfully remade two 20mm cannons. This time the two cannons were much more compact, but there was still no way to carry them around.
However, the remaining part cannot be wasted. After going through the manual equipment, a heavy machine gun full of history was placed on the long table in the studio. After all, the 20mm is probably a little too powerful to hit ordinary bugs. Eliminate those
For something that rushes out headlessly, .50 is just right. Of course, this name must be 12.7mm. This is a kind of belief.
It has a square receiver and a thick cylindrical barrel, which can be mounted directly to the quick-change heavy barrel in one step. However, the worse thing is to use a leather belt because the shipping industry is underdeveloped and there is no canvas here!
Although Polu still remembers the structure of the shotgun chain, the shape and required accuracy are actually not something that can be made with a wave of hands. Although it is definitely an advanced direction, let's put it aside first. Wait until it can be scattered
Once the bullet chain stamping is successful, it will not be too late for mass production.
"Hippolet, let's go to the dock!"
After the last experiment, the water in the dock has been drained again by several sets of water pumps driven by the steam engine, and the small sampan has returned to its support.
Polu stood on the edge of the dock and watched two long forged spindles being transported in by tractors, along with a batch of sand-cast propellers and a bunch of strange rough gears.
"Does this mean that I have to pick it up and use it, and I have to polish it myself? Forget it, let's start with the modification of the hull first."
The shipbuilding workers were summoned, and Polu explained to them several major changes: "Come on, friends, the keel and ribs will not move, dig a hole from this place, and make a bushing like this
.The same is true on that side! Let’s change the hull first, and then I’ll assemble the mechanical part!” He patted the drawing in his hand.
However, it backfired. After all the hard work, the best parts were selected from the accessories, the transverse crankshaft was cut off and changed into a bevel gear transmission, and the assembly was completed. Bolu, who had been worried for a long time, screamed in despair: "Ah
!You don’t need to look at this to know it’s leaking!”
What can be done? There is no way. I tried to use high-viscosity lubricating grease to plug it, but there was none. In the end, I could only use a copper bowl supported by a spring to buckle it to minimize the water seeping from the bushing. However, a
It was obviously not enough, so I had to buckle another one. Unexpectedly, after buckling two or three like a matryoshka doll, the amount of water leakage seemed to be acceptable?
"Maybe it's because the draft is shallow and the water pressure is not that strong? The shaft is not too thick. Besides, the hole is not big, and there is a bushing on the outside to block the water. The lubricating oil project must be started later. I feel like now
There is a shortage everywhere." Bolu thought to himself, and installed a fence on the tail warehouse, and also installed a double-door water pump on the left and right sides that he had prepared when he felt that there might be a water leakage problem.
.
Just leak it! Just leak it in this basin! I will treat you as a counterweight in the tail position! As long as I pump it faster than you leak it, it will be fine!
After experiencing a series of horrific incidents including but not limited to the rudder being stuck and unable to turn, being unable to reverse, the boat tilting as soon as the propeller was turned, and emergency water leakage repairs, etc., this line has been pulled back by tractors many times.
The experimental boat, which is just a fishing boat and the size of an inland river fishing boat, was finally capped and decked.
"Fortunately, this thing doesn't need to be loaded with coal, otherwise this size would be really impractical. But even though it doesn't need to be loaded with coal, it still has to carry distilled water, which still takes up enough space. It's okay, it can be used at least! You can go out for a run tomorrow.
Let’s take a look.”
The next day, the people Polu invited yesterday were waiting at the small dock used to transport food.
Polu drove directly out of the dock today. He stood on the operating deck on the head of the steam engine. When he saw the people on the dock, the smiles on their faces were like a rich man returning home. He was still far away, so he rang the ship's engine.
The whistle!
He maneuvered the experimental ship to float closer to the pier, and Pauleicht threw a thick cable to Leonardo: "Captain, do me a favor, first pull it closer, and then tie the cable!" Several people
Working together, it took a long time to get the boat to the dock.
Yes, Polu is a newbie, but who is not a newbie in this place?
Pauleicht was about to move onto the gangplank of the ship when he saw Leonardo "Hey!" jumping onto the bow of the ship.
"?...You will definitely be a good dancer in the future!"
Seeing her teacher's bad example, Leah jumped over without hesitation. Little Irene hesitated, then also held up her skirt and jumped over on tiptoes.
"..." You guys make me feel uncomfortable like this.
"It seems that the teacher didn't come." There was no figure of Landau on the pier, which was a little regretful.
However, there is still a rare visitor left on the pier at this time: the magical otaku Zhu Yiwei.
Yesterday I met her when I went to greet the teacher, and I invited her by the way. I didn't expect that she would actually come today. Although she was still wearing the same robe, she seemed to have tied her hair?
When she saw the three people jumping over, she showed a slight look of disgust on her face, as if to say: "Rude!". However, she couldn't afford to offend these three people, so she had to pretend to wave her hand gently to block her own.
expression, and at the same time cast a spell on himself.
Just the hem of her skirt was fluttering, and she was already floating in the air, stepping onto the deck lightly. Without hesitation, she walked around the strange long strip-like object covered with cloth on the deck and came to the operating table.
Then he looked at the surrounding settings with a critical look: "I'm very curious about the power of this ship. How does it move?"
The Master should never be offended, and women should never be offended. The female Master should never be offended. With this mentality, Polu briefly explained to her the principle of operation.
During this period, Polu originally wanted to start the boat and leave the dock. Fortunately, Leonardo found that the cable was still tied to the dock. Before Polu could stop the boat, he jumped back to the dock and untied the cable, and then used force again, high
He jumped back high, fully demonstrating his muscular qualities.
Another position on the small operating table was occupied by Zhu Yiwei. After Brecht returned, he found that he had nowhere to go. He could only squat in the engine room and watch the operation of the steam engine and the leakage of the propeller.
Polu stood in the driver's seat on the left, wearing a big-brimmed hat, with the word "Zhi De" written on his face. Under his feet was a new model of 4-cylinder steam engine pushing the crankshaft to drive the rotation of two main shafts.
There are four flat windshields in front of him, and there is a searchlight on the right, which really brings out a lot of new things.
There is no doubt that Polu was not involved this time. Out of long-term considerations, he often just prepared the design drawings and gave them to the workers to process on their own.
At this time, it was time to harvest! He held the steering wheel in his hand and shouted to everyone on the deck: "Get ready to go! Bicycles enter one!"
But he was thinking in his heart: "Later, we should let the workers who built it come up and have a sit."
