The students turned their eyes to Awei again.
Seeing this, Ah Wei frowned and nodded:
"I'll go down and try..."
......
After a short break and meal, Class 9 finally recovered from their previous fatigue.
Now, they all looked at the wood at the back of the warehouse with interest.
I started to think about it constantly in my mind.
How can these woods be made into ships?
They were thinking about this question during lunch.
Although I asked my own teacher during this period.
However, the answer given by Ren Yan did not surprise the students too much.
"You have to do this by yourselves~"
"I'm just helping with some details."
In response, the students could only silently give the middle finger and take out the design drawings drawn by Xu Kai to start analyzing them during their post-meal nap.
After a period of brainstorming and data research, they temporarily divided shipbuilding into three steps.
The skeleton, the outline, and the final shaping.
By following these three steps, even if you make mistakes along the way, there will be enough room for modification so that you don't have to start over completely.
The first and most important step is the skeleton.
As the support for the entire ship, the frame must be rigid enough and the weight it bears must be perfectly dispersed.
Only in this way can the entire ship achieve the goal of being navigable.
This is not difficult with the help of Wang Yu's calculations.
Among the skeleton, the most important one is the keel.
It can be said that the keel is the core of a ship, which is equivalent to the backbone of the entire ship. All the scattered constructions originate from the keel.
The decks, cabins, bows and steering wheels all radiate from the keel.
After a brief hesitation, the students in Class 9 decided to start with the dragon bones.
Only when this thing is done can they carry out subsequent division of labor according to the specifications of this main vein.
Otherwise, everything you say will be in vain.
Do it when you think of it.
The execution ability of Class 9 was once again demonstrated at this moment.
After they picked out a suitable piece of wood, they took the electric saw and prepared to cut it according to the mark they had just drawn.
The dragon bone, in fact, is a long and straight horizontal beam.
As long as they cut the shape they want and polish it, there shouldn't be any problems.
However, just as they were about to take action.
There was an exclamation from the side immediately:
"Hey, you, put the fucking chainsaw down!"
When the classmates heard the sound, they looked and saw Ren Yan running over in a panic.
What happened to my teacher?
Is your butt on fire?
The students of Class 9 were somewhat confused.
Just as I was about to ask a question, I saw Ren Yan turn off the power without saying a word, snatched the chainsaw from a classmate, and said angrily:
"Is this how you play with chainsaws!?"
"He's holding the chainsaw straight up, planning to cut it in with brute force?!"
"Aren't you afraid that you might become disabled for life if you're not careful?!"
"I thought you had made a very thorough plan this time! You've taken all the necessary considerations into account!"
"But how come they didn't even think about the most basic safety aspects?!"
"Can a chainsaw be used in any way?"
"It's this extra-large chainsaw!"
"Even if it's an angle grinder, doesn't it need protection? Not to mention a chainsaw!"
"Do you want to die or live?!"
Ren Yan's angry words stunned the students. They could see that their teacher was really angry.
But the chainsaw...
Isn't it enough to just turn on the electricity and saw?
Any other questions?
Looking at the expressions of his students, Ren Yan sighed deeply in his heart.
These guys really don't realize this...
Helplessly, Ren Yan could only demonstrate like the student just did.
Ren Yan was seen holding the handle with both hands, standing straight, bending his waist slightly, and cutting the wood in front of him.
Later in his demonstration, the phone instantly "slid across" the wood, and finally "cut" into his leg due to inertia.
Then, Ren Yan picked up the chainsaw again and looked around:
“Did you see that?!”
"This is what happens when you use a chainsaw like this. It's a good thing the teacher didn't turn on the power just now."
"If this is electrified, what would be the consequences?"
"The chainsaw cuts so fast that the resistance of the wood is almost negligible."
"You guys are still holding your hands, cutting down desperately, who else can you cut if not you?!"
"Can't you read the instructions before using it?"
Ren Yan glared at the students with disappointment, then reconnected the power to the chainsaw. After pressing the button, the buzzing sound that broke through the air was heard again.
He began a new demonstration.
"Look, this is how you use a chainsaw correctly!"
"The bottom line is that you need to keep your body stable, and it's best to form a triangle with the ground. It doesn't matter whether you squat or stand."
"But make sure you stand sideways from the direction of the chainsaw. Don't just hold the chainsaw in front of you and start sawing."
"At the same time, the handle of the electric saw can be held with one hand, and the other hand should hold the raised area above the handle."
"This is where your second hand should be held, so that you can effectively control the chainsaw and prevent it from going off the track."
