Sun Hang just shrugged his shoulders and said,"
" This is the 20mm picatini system on the gun. It can be used to install flashlights, sights, and so on…"
After hearing Sun Hang's words. Hu Qinghe quickly looked down at the tactical rail system that Sun Hang had just sketched out.
When he saw the details, he realized that he was overthinking.
In the next moment, Sun Hang could clearly see the disappointment on Hu Qinghe's face.
In order to hide his embarrassment, Hu Qinghe quickly pointed at the structure that Sun Hang had just drawn and said,"
"There seems to be something wrong with your three-dimensional view. This place should be a right angle, but you used a circular angle. You can take a look…"
Sun Hang took the paper from Hu Qinghe's hand and looked at the place Hu Qinghe had pointed out. His eyes lit up.
Indeed, the three-dimensional view of this place was because he had made a mistake when he drew it.
What Sun Hang didn't expect was that Hu Qinghe only took a glance and immediately saw the mistake.
As if he could see the look in Sun Hang's eyes, Hu Qinghe quickly shrugged his shoulders and said,"
" My main job in the military factory is drawing. I can easily draw the structure of a 20mm picatini system like yours..."
Sun Hang didn't expect his roommate to be a drawing expert.
However, drawing was his weakness, so Sun Hang quickly asked Hu Qinghe if he could help him draw.
Hu Qinghe was also generous, saying that he had nothing to do in the military factory during this period of time, so he went to the factory every day to read.
At the same time, Hu Qinghe patted his chest as he listened carefully to Sun Hang talk about the function of the tactical rail system and the standards of the various size materials. He said,
" Give me this blueprint. I'll be able to draw it all for you before noon tomorrow…"
Hu Qinghe and Sun Hang discussed for a long time. They only went to bed late at night.
……
The next morning, when Sun Hang woke up, Hu Qinghe had already left the dormitory.
Sun Hang went to the cafeteria to buy two steamed buns. After eating a sumptuous breakfast, he immediately went to the labor service company.
When he passed by the washroom, he immediately saw a familiar figure washing clothes there.
It was Mo Xinyu.
At this moment, Mo Xinyu was boiling a pot of water. She placed a piece of cloth in the basin and poured it over the pot.
In the 1970s, regardless of whether it was men or women, everyone in the factory liked to wear a kind of cloth called the Ministry of Labor.
The fabric was usually dark blue and very durable.
Some fashionable youths just liked to use hot water to heat the entire piece of cloth.
The dye on the fabric would turn light blue under high temperature.
This light blue fabric was similar to the material of jeans nowadays.
Then, they cut the darker fabric that had not been ironed into patches and sewed them directly on the knees and other places that were easy to wear.
This way, it could embellish the simple denim clothes and pants, and it could also wear them.
In this era, apart from the Ministry of Labor, there was also a kind of high-end fabric that people thought was very expensive…It was indeed cold.
This kind of modern chemical fiber fabric, which was refined from crude oil, was like a luxury item at that time.
The boy made a shirt out of Dusk, which looked even better than Dior.
The girl wore a dress made of duster as if she was wearing Chanel.
Sun Hang greeted Mo Xinyu from afar.
Mo Xinyu immediately raised her head when she heard that.
However, the next moment, Sun Hang saw Mo Xinyu's pretty face turn slightly red as she nodded her head slightly, which was considered as a greeting.
Just as Sun Hang was about to turn around and continue walking toward the labor service company, he heard Mo Xinyu calling out to him from behind.
"Sun Hang, do you want to have lunch together?!”
Sun Hang stood still and turned his head. After thinking for a moment, he smiled and nodded.
Anyway, there was no point in him eating alone.
It wasn't a bad idea to have a meal with a beauty like Mo Xinyu.
When they arrived at the labor service company, the others had not gone to work yet.
Sun Hang went straight to the boring machine.
" Congratulations, Host. You have successfully signed in…"
" Reward: Level 8 National Boring Machine Skill..."
Sun Hang immediately felt a warm current flowing through his limbs and bones.
Then, he had a deep understanding of the usage of the boring machine.
Boring machine was a machine tool that mainly used a boring knife to bore the existing pre-fabricated holes of the work piece. Usually, the boring tool rotation is the main motion, and the movement of the boring tool or the work piece is the feed motion.
It is mainly used to process high-precision holes or complete the finishing of multiple holes at one time. In addition, it can also be used to process other processing surfaces related to hole finishing.
Using different tools and accessories can also be carried out drilling, milling, cutting processing accuracy and surface quality is higher than the drilling machine. The boring machine was the main equipment for processing large box parts. Thread and processing of the outer circle and end face.
Sun Hang slowly let out a sigh of relief and directly found an aluminum alloy plate from the pile of materials.
In order to make the 20mm picatini system, it was naturally best to use a lighter aluminum alloy material.
