Chapter 268 Overtime work will damage money! [Please subscribe]

Time passes by minute by minute.

Ren Yan naturally didn't expect what kind of storm he had brought about.

Wait thirty minutes later.

Ren Yan slowly opened his eyes and started the next work.

He walked to the earthen fumigation device and opened the side door.

A large amount of steam surged out in an instant.

After the steam completely dissipated, Ren Yan came to the wood in three or two steps and touched it slightly with his fingers.

The texture of the wood is now very different from before. It is no longer as hard as before, but is a little soft.

Seeing this, Ren Yan nodded.

Take out the wood directly and extinguish the charcoal that is about to burn clean.

Then the wood was placed on the aluminum basin I prepared before, and some bricks were placed on the corners.

Under the aluminum basin, some lit charcoal was still placed.

After doing this, Ren Yan looked at the students in Class 9:

"The wood is fumigated so that it can be clearly felt soft inside and slightly darker in color."

“There is then a need to plasticize the wood by heating.”

"The fumigated wood alone is not enough to complete the molding, and the temperature must be maintained to one point."

"The plasticity point of each wood is different, and you can search or test this later."

"And you must be patient during the shaping process and complete it step by step. Never use too much force, otherwise, all you can get will be a piece of wood with a lot of cracks inside."

"This kind of wood is light if it is accidentally dispersed."

While speaking, Ren Yan used his hands to slightly bend the piece of wood in front of him.

The expression is particularly serious and the bending speed is also very slow.

If it weren't for a long time, there wouldn't be even visible signs of Ren Yan's hands moving with the wood.

But in this slowness, the wood gradually deformed.

About twenty minutes later, a curve that was so exaggerated that it was impossible to appear on the wood was completed.

Ren Yan took the wood that looked like a crescent moon and nodded with satisfaction:

"This is the arc wood you want. With the blessing of this arc, there should be no problem to make a suitable keel."

"As for the rest, the use of natural air-drying and mortise and tenon structures."

"I have talked about these things before, and I have actually done them, so I won't say more."

"You just need to know that the wood must be air-dried until the color is restored to 80% or 90% and has a perfect wooden feel to the touch."

"Otherwise, it will not be perfectly suitable for other woods."

After saying that, Ren Yan threw the wood in his hand towards the students in Class 9 and walked towards the chair again.

This time, the wood Ren Yan chose was not big. If it was huge, the time spent would probably be super doubled.

After taking the wood thrown by Ren Yan, the entire Class 9 carefully observed it and kept recalling Ren Yan's actions just now.

Soon, they felt that they had mastered this technique.

Start preparing to make some new fumigation devices.

With this technology, are they still afraid that they can't handle the keel?

Therefore, they quickly took action.

Only Wang Yu felt that things might not be that simple.

Before the action, I pulled my classmates and asked them to tell me how to play mortise and tenon.

He felt that only in this way could he consider it more perfectly.

However, the answer I got was:

"I can't explain it clearly to you now, you have to practice this thing."

"Do you understand the practice? It's the kind of thing you like the most!"

Regarding this, Wang Yu was speechless and could only act with the students in Class 9 in shame.

However, the uneasiness in his heart became stronger and stronger.

Is it really that simple to build a giant keel?

over time.

When night approached, Class 9 had completed all the fumigation devices.

In the fenced areas around the warehouse, one earthen fumigation equipment after another has been erected in all sizes.

And during this manufacturing process, they discovered how pitiful this method is.

The fumigation wood that my teacher chose at that time was only twenty or thirty centimeters, so the equipment used was naturally small.

You can make it by just using your hands, just like building blocks.

But once the volume of this kind of "building block" is over, the difficulty is not at the same level at all.

Any problem that is originally negligible will be infinitely magnified.

Assembling a shell alone took a lot of their time.

They were forced to review the mortise and tenon structure, although it was still the simplest way to connect.

But after all this afternoon of influence, he felt that his previous feelings had come back and even surpassed them.

In this process, Wang Yu also understood the actual use of mortise and tenon.

And in the afternoon, I used some small carpenter utensils to compete with mortise and tenon, but I could never make a perfect mortise and tenon.

The spliced ​​outlines are always shaking, and the analysis between them also appears and disappears with this shaking, but they just don't collapse.

It's really like a figure with poor workmanship.

It made him extremely tired.

Whether or not, Teacher Ren’s metaphor is always so appropriate.

In addition to the splicing of the shell, the bigger problem comes from humidification and fire protection.

Because the wood that needs fumigation is conservatively estimated to start from three meters, their fumigation equipment is particularly large.

Soaking all in water becomes a very tedious thing.

Moreover, the charcoal is needed for fumigation inside, so the heat energy generated becomes thicker.

Ordinary soaking may not have any effect at all. It will be evaporated by charcoal in minutes, which is much faster than the speed of water vapor generation.

They have done experiments on this.

After thinking about it, they could only choose to soak the wood before splicing the shell, so that the best fireproof effect can be achieved.

Or make a bunch of fireproof bricks again and use fireproof bricks to build the shell.

But this idea was extinguished by the students in Class 9 as soon as they were born.

I'm afraid they won't be able to start the action next week

And besides these, the most difficult point is the temperature control device.

It looks simple and the principle is not complicated.

The small balls on the cabin are just rotated by the size of steam in the cabin, and then the connecting wooden board is pulled by the rotation speed to achieve a balanced effect.

But when they really do it, they know how difficult it is to achieve this process.

They took a long time to make a spinning ball work.

Finally, after removing the control device of their teacher, they barely understood the structure and replicated it.

During this period, they wanted to listen to their teacher's suggestion and connect this thing with a thermometer.

For this reason, they also bought several large thermometers.

But no matter how hard they racked their brains, they would not be able to achieve their goals.

Either the thermometer is broken and cannot be used.

Either it is connected on the surface, but in fact the two are not related to half a cent.

In the end, they had to choose their own teacher's method and leave everything to nature.

This also allowed them to fully understand the differences between demonstration and actual operation.

No wonder many things are good during the demonstration, and they praise them as soon as they are actually in practice.
