N-A-A Chapter 406
Chapter 406
If a worker wants to do a good job, he must first sharpen his tools!
For building ox carts, Lu Zhe has quite clear ideas.
The first is to divide the trees:
thin abaca rope as ink thread, chicken blood as ink.
There is a tape measure in the toolbox.
Lu Zhe used a straight bamboo strip to reproduce a long scale.
Then use the steel wire to carve the dent to make a wire saw!
A simple set of woodworking tools is basically complete.
Draw the dividing line with ink lines and you can see wood.
First cut the 5-meter tree segment into two segments, one 3 m and one 2 m.
Logs 3 meters long and 50 cm in diameter, sawn from top to bottom into 10, 8, 8, 6, 6, 4, 4 cm thick wood chips.
There are many losses large and small, and they are normal.
Then smooth these chips with a planer as much as possible.
Take a 10 cm thick piece of wood and cut off the two corners to form a thick wooden block 10 cm thick, 20 cm wide and 3 m long.
Then use a pencil to draw two large wavy recesses on the thick wooden board, sawing off the excess, like a giant recurve bow.
This is the "Hengmu", also known as the "ox martingale", which is mounted on the back of the cow's neck to provide power.
In order to better control the course of action of the ox, Lu Zhe gave up the rope pull and connected a "yuan" wood in the middle of the ox martingale as a pull transmission.
This does not require nails, only a simple mortise and tenon structure to fit tightly.
The skeleton structure of the car is very easy, with a "by" shaped main frame of purple nan wood, which is also a mortise and tenon structure.
The top end of the word "by" is connected to the martingale, and the middle one is "horizontal" under which is framed with a wheel axle.
In order to reduce weight, the rest of the material is made of lighter bamboo.
For example, the car board made of bamboo pieces, the fence and handrail built of bamboo segments, and the awning woven from bamboo.
The bearings can be directly disassembled from the bearings of the aircraft and are quite rounded.
The key is the wheel.
This is also the most complicated step in the entire oxcart!
Lu Zhe tried to use a lazy method, he sawed two log segments directly from the 2-meter-long log as wheels, but found that this thing was too small and bulky, the center of gravity of the car was low, it was not fast to walk, not to mention the loss of a lot of kinetic energy, and it was easy to be hindered by the bushes on the ground.
Give up and throw it to Asa and Yaoyao to make a cutting board.
But because the installation test was carried out, there was a small hole through the bearing in the middle of the two cutting boards, and the two girls had to cut two more small sticks to block the small hole.
It seems that if you want to be lazy, you can't do it, you can only make a serious wheel!
First determine the size of the wheel, remove a certain steel ring of the aircraft engine, 90 cm in diameter.
Lu Zhe made wooden wheels according to the size of the steel rim.
First of all, you need to do "hub"!
That is, the round log supported by the bearing connection spokes.
And cut 12 small rectangular holes in it!
This requires precise measurements and great patience, and even if the angle is two or three millimeters off, the entire hub may be scrapped.
So just these two "hubs" Lu Zhe took two days to build.
Then there are the "spokes", which are the spokes.
Lu Zhe Lu Zhe made 24 wooden rods that were precisely calculated, and finally of the same length and thickness, with a section of ferrule at both ends, which could be nailed into the hole of the "hub" just right.
Finally, the "rim", that is, the silhouette!
Lu Zhe drew 12 rim parts on 8 centimeters thick wood chips, each with a ferrule at one end and a slot at one end, and then dug two small holes, and each 6 pieces were just assembled into a large wheel.
Put it together and the wheels are ready!
However, to make it strong, it takes another process.
Lu Zhe tried to put the steel ring on the wheel, but he couldn't put it in.
It's okay, dry the grass, charcoal, put it on top, cover it with hay, light it.
The fire was raging, and when these things burned out, they were clamped with iron tongs and put on the wheels, which was just enough to fit in.
Finally, a large can of cool water was poured on the steel ring, and with a "croak", white smoke splashed, and the steel ring immediately tightened.
Then nail the rivets on the plane, and the various parts of the wheel will be tightly locked together.
The other wheel was concocted and installed.
Don't look at the diameter of this wheel is larger than the aircraft wheel, but its weight is much lighter, because the center of gravity is high, so that the angle of the body is flatter, and people are more comfortable to sit on.
It is also necessary to install a brake pin on the body, which is a wooden stick inserted diagonally!
When the cow is crazy and wants to run, the brake pin can be inserted into the ground like an anchor, and the harder it goes, the deeper the thing is inserted, and the more it can't run.
With all this done, the whole frame finally looks presentable.
Then carry out the necessary decoration and refinement.
This process is cumbersome to say and even more difficult to do.
This inconspicuous ox cart, Lu Zhe took a full 20 days to be done.
I didn't do anything else during this period.
On the day the ox cart was completed, Shen Bing couldn't help nodding approvingly: "Lu Zhe, even if you can't find a job in the future, you can go to the countryside to make an ox cart to support your family."
Tang Xiaoguo looked at the ox cart: "If this car is taken to the countryside, it will have to be sold for two or three hundred yuan."
Jiang Yao pouted: "Two or three hundred? Two or three million is about the same!
Ning Shu shook his head: "But I guess it shouldn't be the uncle farmer who really wants to buy it, but those collectors." The ox cart made of golden silk nan can be sent to the museum. Shallow
said: "Anyway, this is our first land transportation, everyone still has to support Lu Zhe." "
The ox cart is done, the next step is to choose the cattle!
Now Lu Zhe has five bulls and two cows, including Haiyan and Yongqiang, and Haiyan who can still produce milk and Yongqiang, who is sub-mature, are not suitable for pulling carts, and should be selected among the other bulls.
Lu Zhe selected the two strongest bulls and added a car cover to them, but the white-necked bull said nothing!
Several girls began to exhort:
"Look how expensive this cart is, the most noble ox in the world can pull such a valuable ox cart, this is a platform for humans to show yourself, you should be content and grateful!"
"Just pull this up! You are the Lamborghini of the cow world! "
Lu Zhe said, as long as you pull the car, he will give you the opportunity to be alone with Haiyan..."
The cow understood this, and shook his head or did not do it.
Shen Bing began to sharpen the knife.
She believes that it is useless to keep the cow that cannot pull the cart, it is better to make roast beef, sauce beef, braised beef and beef jerky!
As a result, the knife has not been sharpened, and the cow's IQ seems to have increased a lot in an instant, and he actually understood everyone's words and gladly put on the ox martingale.
In Shen Bing's words: "The cow is not an ordinary animal, it doesn't say anything, but it understands everything!" Lu
Zhe took the extended leather whip and sat on the ox cart, gently whipping, at first the two cows could not move forward together, and after two days of domestication, they could finally obey the simple "drive over" password.
Next, Lu Zhe wanted to open up several routes that could drive ox carts.
