"Shipbuilding: From Raft to Black Lake Explorer"

I. Introduction

……

[-]. Preface (Principal Dumbledore, Professor Flitwick, etc. are invited to write the preface)

……

[-]. Theoretical study and exploration

……

[-]. Specific Exploration Process

Making the raft:

1. 4 pieces of wood with a diameter of 40 cm. The members search for suitable wood by themselves - material search and identification

2. Flatten the middle of the wood - precise use of the cutting spell and patience training

3. Side by side, with the plane facing up, tied together with a strong rope - the application of the binding spell

4. Tie suspended objects around, for example: bottle - Muggle common sense

Note: For 20 cm water depth only - ship tonnage estimate

The operation is too simple, only for trial use

Number of experiments: 3

Experiment result: success

The purpose of the experiment: familiarize yourself with the ship making process, understand certain basic knowledge, train cooperation awareness, and enhance the use of magic power

Failure experience:

The first failure: Even if it is repeatedly emphasized in advance, most people still do not realize the importance of materials, sizes, and operating specifications.Proceed to step 3, choose to give up after discussion and redo.

The second failure: the raft was launched into the water, and it fell apart halfway through the journey, which was found to be a binding problem.Instruct relevant personnel to learn and improve.

Achievement harvest:

The relevant staff clearly realized the difficulty of making ships, and promised to study and study the key points of shipbuilding knowledge drawn by me.

The teamwork spirit and operation awareness have been improved.

Making a wooden boat:

1. Choose the red heart fir that grows naturally on the top of the mountain - the material is obtained

2. Log cutting, board breaking, and board splitting—fine operation

3. Assembly of parts - drawing recognition, combination of magic spell and manual operation

4. The shape of the bottom of the ship - the difficulty is too high, skill learning and experience accumulation

5. Gap filling——patience and care

6. Water-proof and anti-corrosion - meticulous and repeated

Note: Experience and technology are required, and the difficulty is relatively high

Number of experiments: 6 times (currently)

Experiment result: failed (currently)

The purpose of the experiment: to be more familiar with the operation process, to lay a solid foundation for the next step of the Black Lake Explorer, to troubleshoot problems in advance, and to find methods

Failure experience: (due to too many failures, no explanation will be given, only a few important questions will be extracted)

1. The parts are not polished and smooth, so they cannot be assembled - the problem of the curse, I have consulted Dean Flitwick

2. The shape of the bottom of the ship cannot guarantee the symmetry of the flaps at both ends of the bottom of the ship—there is a lack of tools, and relevant information has been consulted

3. The hull is leaking, and the splicing gap has not been tightly plugged—the relevant person in charge and the acceptance team have been ordered to rectify

4. Water leakage on the ship deck - the reason is unknown, there are related speculations, pending verification

Alice sighed, put down the parchment in her hand, and turned to look at the busy people by the Black Lake.

Gryffindor was the most active, carrying the materials around with the Levitation Charm.It's just that many of them just run around without planning, which only increases the workload of transportation.

This experiment was in the morning, and Ravenclaw mostly studied in the library, so not many people came.A few are arguing fiercely over construction drawings.The battle was so fierce and the emotions so intense that Alice even felt that they were going to lose their temper in the next second.

There were surprisingly many people from Slytherin.In a way, they are quite united?Unexpectedly, Jarvis really took care of that Buster.

Alice didn't like the arrogant Slytherin.Although he is the president of the student union, he is still far behind Senior Sister Caroline.

But it was a wise decision to let Slytherin be the acceptance team.Perhaps because of the influence of the dean, they always give people the sense of sight that they will criticize in the next second.

Especially for Gryffindor, in the first two hours, Alice has seen three quarrels.

The Hufflepuffs were the most numerous and good-natured as always, except that they were extraordinarily busy at times like this.Passing Ravenclaw's task requirements, mediating the conflict between Gryffindor and Slytherin, really running around like a little badger.

"Did they fight?"

"No, no, they are scolding each other."

"Calling what? Slytherin's viper, Gryffindor's fool?"

"Yes, I can recite just a few sentences."

"No point, I'm betting they'll fight before it's over."

"Don't talk nonsense, do you want to see it or not?"

"Look, why don't you watch the fun?"

Well, Alice listened silently, and decided to give up the idea of ​​changing Hufflepuff's mission.

"Do you think it will work this time?"

"It can't be guaranteed, but the possibility is very high." Alice looked at Bill beside her, "Learning the lessons from the previous few times, there have been many improvements this time."

Professor Flitwick kindly provided a self-created smoothing charm, which at least ensured the splicing of the parts.

For the flaps of the bottom of the ship, experienced masters will use ropes, iron nails and other tools to align the bottom of the ship that weighs tens of kilograms little by little.

Of course they can't do it, but magic can make the impossible possible.The frame is traced first, and then the bottom of the ship is overlapped with the frame with a magic spell after fixing. There is no requirement for strength and angle, which greatly reduces the difficulty.

The gaps between the planks were tightly sealed with putty and hemp silk in strict accordance with the requirements in the book.The operator has been replaced by the most careful Hufflepuff from Gryffindor, and there are Slytherin inspection and supervision. Alice is still very confident about this place.

Pour the burned diesel oil on the boat, let the diesel oil permeate into the wood evenly, and then brush it with tung oil three times before launching it into the water after it dries out.

The process would have taken weeks, but with the help of the Quick Dry Charm, they only took a few hours.With this layer of protection, water leakage is no longer a problem.

Bill didn't interrupt, and listened patiently before answering: "It seems that the success rate this time is very high."

"You can't slack off." Alice looked serious, "Even if it succeeds, it's just a wooden boat, and it's still a long way from the Black Lake Explorer."

"But we have Alice, don't we?" Bill half-jokingly repeated the slogans that have been circulating at Hogwarts these days, successfully making Alice blush.

"That's what they were joking about." Alice refused to continue such a shameful topic, "I heard that you have been in a bad mood recently, what happened?"

Alice had taken the matter to heart since Charlie had mentioned it once.But after all, they are in different grades and different colleges, and the chances of the two meeting each other are much less than before.

She thought about looking for Bill after she finished her work, but today was reviewing for the exam, and tomorrow there was a problem with the experiment, so she dragged on until now.

"Charlie told you." Bill guessed the truth at once, "It seems that I have to have a good talk with him."

Alice touched her nose, I'm sorry Charlie, it seems that you need to feel your brother's love.

"So you're really in a bad mood, and even Charlie can't know why?"

"It's nothing, but he's still young." Bill felt helpless, "It's useless to know, it will only make him worry in vain."

"I'm not young anymore, I'm still one year older than you." Alice raised a finger, "So can you talk to sister Alice about brother Bill's troubles?"

"You really want to know?"

"Do you want to hear the truth or the lie?"

Bill smiled: "I'm curious about the truth and the lie."

"The lie is that I am a considerate senior." Alice skillfully showed a professional prefect smile, "It's okay for the junior to say it if he really doesn't want to."

"What about the truth?"

"The truth is that I am very worried about you, and I hope I can help you." She put away her smile, "Please tell me your troubles."

Bill looked at the sky, the sun was about to set, and the sunset covered everything with a red veil, and even the Black Lake added a bit of romance and tenderness.

Although the headmaster supported the students' exploration attempts, relevant regulations were formulated at the request of the professors.One of the most important ones is to control the duration of extracurricular activities so as not to affect normal learning.

"It's getting late now, is the boat about to launch?"

Alice restrained her urge to turn around: "It's not a good boy to answer the question directly and change the subject."

"Actually, you knew it before." The good boy Bill finally chose to answer the question honestly, "It's still about my going to Egypt to raise dragons."

"Mrs. Weasley's attitude still hasn't softened?" Alice was a little surprised.After so long, since Mrs. Weasley knew that Bill was serious, she shouldn't be so obstructive.

Bill shook his head: "The situation is a bit complicated, you don't need to worry about me, I just want to think carefully."

"After all, it's about the future, so it should be considered. If you..."

"Successful!" There was a burst of cheers not far away, Alice turned her head suddenly, and saw the small wooden boat under the sunset.

"Great! All the preliminary experiments have been completed, and we will start manufacturing the Black Lake Explorer tomorrow!" There was only this sentence left in the air, and when Bill recovered, Alice was no longer in sight.

Looking up, by the lake in the setting sun, Alice waved to him excitedly, her blond hair was even more dazzling under the sun.

Bill moved his mouth, but he didn't speak in the end. He smiled and waved in response.

--------

The making of Black Lagoon Explorer:

1. Dig out a large enough pit, supplemented by wooden piles and stones, and build a dock.

2. Production of components such as keels, side keels, ribs, and dragon tendons (pay attention to the use of magic spells and learn from previous lessons).

3. Installation of components:

Make sure the ribs are warped at the ends and straight in the middle.

Pay attention to the installation angle of the side keel to ensure the strength of the hull to withstand external forces.

The hull planks and pine boards enable the hull to withstand longitudinal bending force, water pressure, wave impact, etc.

The mast hole reinforcement plate is vertically interspersed between the deck beams and fastened with bolts to support the mast so that it stands on the inner keel.

4. To fill the gaps, apply diesel and tung oil evenly and multiple times (refer to wooden boat construction).

……

Times: 1 times

Result: success!

Purpose: Black Lake Adventure!

Achievement harvest:

Theory has a guiding role in practice, and scientific theory has a positive guiding role in practice!

The perfect blend of wizarding magic and Muggle science!

Make full use of the power of all Hogwarts students!

The author has something to say:

Various materials in the shipbuilding process are mixed, which cannot withstand scrutiny

I really don't understand this review. It was so slow a few days ago, and it was reviewed again after ten o'clock in the past two days.

It’s been a long time since I’ve been in the literature shortage. I revisited the previous novels and found that I really like gentle, courteous, and reliable male protagonists (only after I wrote this did I realize that he is a gentle gentleman)!

Sure enough, he is no longer young. Not only are his preferences and fashions different, but he can only read sweet and funny articles to get by
