The mortise and tenon structure does not need to use any iron nails, it is reinforced by the mortise and tenon structure, mainly by making a hole in the wooden equipment to install the tenon, which is a very commonly used structure in the building, in which the beams, columns, fangs, backing plates and other components need to be connected with mortise and tenon joints.

Therefore, being able to make mortise and tenon joints is a compulsory course for a carpenter.

Don't look at Tian Zhifu's chubby, less than 1.7 meters tall, weighing about 180 pounds, his movements seem to be very clumsy, but when the chisel and hammer are in his hands, he immediately seems to be a different person.

Agile and precise, he first flicked a standard square eye with an ink cartridge on the wooden board, and then began to chisel......

This is a socket eye, and after chiseling, Tian Zhifu made a corresponding tenon.

Wang Jing was on the side, and explained to the apprentices who were watching the excitement, and said:

The type of mortise and tenon, according to the different needs, is divided into many kinds, such as notch tenon, tongue tenon, dovetail tenon, wear belt tenon, tenon and so on.

The other type is the structural method as a point, which is mainly used for horizontal and vertical T-shaped joints, angular joints, cross joints, and extension joints of straight and arc materials, such as lattice shoulder tenons, double tenons, double clamp tenons, hook tenons, wedge tenons, half tenons, through tenons, etc.

There is also a kind of construction method that combines three components together and connects with each other, this method in addition to the use of some of the above mortise and tenon joint structure, are some more complex and special practices, such as the common supporting angle tenon, long and short tenon, shoulder tenon, zongjiao tenon and so on. ”

Wang Jing is also a treasure.

The apprentices listened with admiration.

I didn't expect Wang Jing to usually talk much, but he understood so much.

Liu Wan was also shocked by her son.

It turns out that Wang Jing's genius is a real genius, but he is also really diligent.

With so much knowledge of mortise and tenon structure, it is difficult to understand how he obtained it in ancient times when information was so poor, which shows how attentive he was.

At this moment, Tian Zhifu finished the mortise and tenon joints, and when he inserted the finished tenon into the socket, it was tightly knit and the score was exactly right.

After Tian Zhifu finished doing it, he looked at Wang Jing's appreciative expression, and said expectantly:

"How about it, Master Wang, can you take me?"

"You can accept it, but you have to get the consent of the elders in your family."

At this time, Liu Wan put forward a reasonable condition.

When Tian Zhifu heard this condition, he muttered:

"If my father had agreed, I would have stopped going to school a long time ago and would have gone straight to becoming a carpenter."

Liu Wan smiled. If this guy were placed in the modern world, he might have become a master of woodwork.

It's a pity that in these years, all those who do crafts are listed as the bottom nine popular columns.

Since Tian Zhifu's father is rich, he will definitely not let his son do this kind of ninth-rate work.

Tian Zhifu is self-aware, and he just asks to be able to enjoy it.

Liu Wan saw Wang Jing's admiring expression, so she said:

"How? Tian Shao's craftsmanship is okay, right? ”

"In good conscience, it's good." Wang Jing said to Tian Zhifu Yan Hong, "Like my mother said, if your parents agree, I can teach you, but we can't be commensurate with master and apprentice, so you should come and play." ”

When Wang Jing talked about this, Tian Zhifu knew that it was impossible for Wang Jing to accept him as an apprentice for a while, he could understand Wang Jing's situation, and it was inconvenient to embarrass him anymore, so he said:

"Well, I'll get my father's consent, and until then, I'll come often when I have time, and you'll have to teach me the woodbirds' techniques."

Don't worry, I won't pass it on to outsiders, I'm just thinking about it myself and learning to play. ”

Wang Yi'an also vouched for his classmates and friends at this time, saying:

"Brother Tian has always kept his word, do what he says, don't worry."

Tian Zhifu took the initiative: "If you teach me the skills of making wooden birds, I will pay you 50 taels of silver for tuition, and I promise not to pass on the production skills to outsiders, only I understand and play." ”

Liu Wan didn't expect that this little fat man was quite generous and interesting, which was equivalent to paying a patent study fee.

So, she nodded at Wang Jing.

Seeing Liu Wan's permission, Wang Jing pondered for a while and said, "Okay." ”

Tian Zhifu was overjoyed, and immediately took out a silver ticket for 50 cars, respectfully handed it to Wang Jing, and said:

"Master Wang, while you are free today, I am also here, you can teach me."

Wang Yi'an, you saw Tian Zhifu's obsessive appearance of scratching his ears and cheeks, and said with a wry smile helplessly:

"Brother Tian, you have fun here, I'll go back first."

Wang Yi'an cherishes time like gold, and it is impossible to waste precious time on carpentry.

Tian Zhifu had an interest in sustenance, and he also knew that Wang Yi'an was the one who was going to participate in the imperial examination, so he waved his hand and said:

"Go ahead, I know how to arrange."

"Okay, call me again if you have something." Wang Yi'an also left.

Wang Jing happened to be assembling the abacus beads, and he was already very experienced in this process, and he could install it with his eyes closed, so he could teach Tian Zhifu with two minds.

Wang Jing taught Tian Zhifu two essential parts for making wooden birds.

Tian Zhifu is really talented in carpentry, and after studying for a while, he can really do it.

Liu Wanhe and Wang Yi'an left the woodworking workshop together, and she said to Wang Yi'an:

"Yi'an, your classmate and friend are so obsessed with carpentry, so let him eat at my house at noon, and you don't have to come over to call him."

"Okay, then it's going to trouble Aunt Liu."

Wang Yi'an was not polite.

Wang Li is about to go to the Xiuxian Academy, and Liu Wan seems to be interested in making friends with these fellow students, and Wang Yi'an doesn't need to be polite to her, this is also a chance for Liu Wan.

Originally, he also planned to suspend school for a day to receive Tian Zhifu.

It's good now, Tian Zhifu has something he is interested in, and he doesn't want to pay attention to him, Yi An just went back to read poetry and books, and the two of them have their own place.

Liu Wan tossed for a long time, and then remembered that she hadn't seen Wang Li, so she asked the system:

"System, have you seen Wang Li?"

The system didn't reply for a long time, and it is estimated that Liu Wan used it as a locator, which made the system feel very down.

This guy is stingy, and now it feels that Liu Wan uses him as a locator and disrespects its performance, so it doesn't want to answer.

Liu Wan hated the inexplicable self-esteem of the system, so she didn't bother to beg it anymore and went to find someone by herself.

Fortunately, people are not difficult to find, Wang Li stayed in his room, sitting in front of the window, in front of him was a spread out "Three Character Classic", on the table there was a note written by him, it turned out that he was studying diligently.

Liu Wan's heart moved, and she entered the house.

Wang Li heard the movement, looked back and saw her, his eyes lit up, and he shouted:

"Mother."

"Li'er, how's it going? Did you sleep well last night? ”

Liu Wan saw that he had calmed down a lot and his complexion was as usual, so she asked distressedly.

"Very good, mother, don't worry, I was really scared yesterday, but fortunately, Uncle Xie and they were too brave, and they beat each other back at once.

If it weren't for the fact that they covered their mouths and noses, stuffed them into a cloth bag, and blinded their brains, I would have had a lot of fun watching the excitement. ”
