The whole family travels through time and space, and the three of them struggle together

As for Zhou Dajiang, ever since his father-in-law took away his position as teacher, he has been more relaxed at night. After all, he has to submit an article in three days, so he just needs to submit it.

There was just the end left today, so he quickly finished it and handed it to Master Chen. He said goodbye to Master Chen and left the classroom, no, he left the room.

While his third brother is at home, he has to arrange for the meat grinder sample to be delivered.

At this moment, Zhou Dahe and Zhou Dahai were operating a stamping machine to process holes.

Just like modern men like cars, Zhou Dahe has been obsessed with the stamping machine since his second brother explained to him the working principle of the stamping machine, and has been thinking about what else can be processed using the stamping machine.

When he saw his second brother coming over with the blueprint again, his eyes immediately lit up. What new thing needed to be processed?

So, Zhou Dajiang turned into a technical instructor and explained to his older brother and younger brother the working principle of the meat grinder and how to install it.

This time, there are more parts to be processed, and they are much more difficult than the previous small tools. Zhou Dajiang asked his brother to pick out the drawings he could print out first, and then study how to process the remaining parts.

Zhou Dahe first picked out the blade and the shaft core, then the fixed base, and then nothing else happened. He couldn't process the rest.

Zhou Dajiang asked him to choose again and give it a try.

Zhou Dahe shook his head like a rattle. "No, no, I can't do it. The core inside is fine, but the tolerance requirements for the outer sleeve are too strict. I can't do it!"

Seeing that his brother had even considered the tolerance, Zhou Dajiang knew that he had thought it over carefully. He did not force him. After all, if the tolerance could not be met, there would definitely be clanging between the shaft core and the sleeve. Instead of that, it would be better to use wooden products instead.

So, the next day Zhou Dajiang took the remaining drawings to Carpenter Tian's house.

Tian Youcai was working on the lid of a meat grinder. He thought Zhou Dajiang was coming to get the handle, so he pointed to the parts box next to him and said, "It's all done. Take it away."

Zhou Dajiang took out a few drawings from his arms and said, "I'll take the handle away later. The main reason I came here today is to ask you to help look at these drawings and see if you can process them." As he said that, he spread the drawings on the table.

Tian Youcai put down the work in his hands, picked up the drawings and studied them one by one.

"Are these parts from a meat grinder? The tolerances are pretty tight!"

Zhou Dajiang: "Yes, these are the shaft sleeves. The main purpose is to ensure that after the cutter shaft is installed, the shaft core and the shaft sleeve can fit tightly together. The smaller the gap between the two, the better. It would be best if they can achieve a perfect fit."

Tian Youcai nodded. "This is a bit difficult. Let me give it a try. What kind of wood should these parts be made of? Are there any requirements?"

Zhou Dajiang: "I originally planned to make it out of iron, but my third brother said the tolerances were too strict and he couldn't make it. So, I'm thinking of using wood instead. I haven't decided on the specific material yet. However, since this is the shaft of a knife used to process food, the wood needs to be high-quality and resistant to decay and insects. Could you help me think of a better wood?"

Tian Youcai thought for a moment and said, "Caltha, oak, and ash, these three types of wood can all meet your requirements. However, they each have their pros and cons. You can take a look at them.

Let's start with catalpa wood. It grows in cold regions and has a tough, dense, fine, and resilient texture. It also has good workability and doesn't warp easily. The only drawback is that it's too rare and very expensive. I don't have any of this wood.

Next on the list is oak, which has a hard texture, dense structure, smooth cut surfaces, resistance to moisture and wear, and retains its color even after long storage. Its downsides are that it's prone to cracking, warping, and drying quickly. I don't have this, but if you're interested, I know where to buy it.

Finally, there's Manchurian ash. It's slightly harder and more wear-resistant than pine. Its greatest strengths are its clear grain, corrosion and water resistance, ease of processing, and high toughness. Furthermore, it's relatively affordable. I have this one.

When Zhou Dajiang heard the types of wood he mentioned, he realized that the last one was the only one he could choose. He felt a little unwilling and asked, "Are there any other types of wood?"

Tian Youcai said, "As for other hardwoods, there's elm. Elm, along with beech from the south, is known as 'Northern Elm and Southern Beech.' It has moderate hardness and strength, but also has significant drawbacks: a coarse grain and a dark color. I also have this wood."

Zhou Dajiang listened to the various woods he mentioned, weighed their pros and cons, and ultimately chose Manchurian ash. It's relatively hard, corrosion-resistant, and water-resistant, and most importantly, it's relatively affordable, which means the cost of the meat grinder can be relatively low.

The two men selected the wood, agreed on the price, and agreed to deliver the barrel body, lid and handle together in three days.

After the two of them made an agreement, Zhou Dajiang took the last 100 sets of controllers back home.

These three days are just enough time to assemble the 200 sets of parts in hand, and then we can deliver the samples together.

During these three days, except for Chen Xiuying who went to the construction site to cook every day, Zhang and Li would also go over to help when they were not busy.

Zhou Sisi tricked Zhou's mother and Chen's mother into sewing cushions, throw pillows, and headrests for her. In Zhou Sisi's own words, life is about enjoyment. Only when material conditions are good will creative inspiration flow, and she will be able to paint faster.

In reality, she just felt the weather was cold and the stool was a bit chilly, so she tricked her grandmother and grandmother into sewing her cushions, pillows, and bolsters so she could be more comfortable. Moreover, if there were any extras, she could sell them at a fabric shop. She even called it developing a market for handicrafts.

Time flies when you're busy. In the blink of an eye, it was the afternoon of the third day, and Zhou Dajiang went to Tian Youcai's house to retrieve two sets of samples.

Zhou Dahe also completed the meat grinder's shaft, blades and fixed base and sent them back.

Finally ready to assemble!

Zhou Dajiang assembled the parts one by one according to the order of the drawing, put on the lid, and installed the crank handle. And hey, the size was just right. There was no gap after the shaft core and the sleeve were connected, and the blade did not shake. Including the shaft tip part with the mortise and tenon structure, everything was just right.

In order to test the effect, Zhou Dajiang asked his daughter to pull a carrot from the vegetable garden. There was no pork at home, only a whole chicken that had been killed with bones, which could not be used to grind meat. In the end, he had to try it with vegetables.

Zhou Sisi was willing to do this kind of work. She imitated her modern mothers, peeling the carrots with a peeler, cutting them into pieces, and throwing them all into the meat grinder. Then, she closed the lid, installed the handle, and started to crank it happily.

That little look made all the younger brothers and sisters extremely envious. They all stared at it eagerly and wanted to try shaking it.

Zhou Sisi shook the shaker and counted at the same time. When she counted to the 100th number, she stopped, opened the lid and saw that the carrot pieces were almost turned into carrot flakes. She was too excited and accidentally crushed the carrots!

However, this also indirectly proves that the sample is finally completed!
