Chapter 111

"Pull the big saw, pull the big saw, grandma's family watch the big play..."

The stone bear stood not far from the two brothers, the cross saw and the wooden planer, humming the children's songs that his grandparents sang to him when he was a child.

Double lift big saw is a special weapon against big trees, just like the curved yuan plow for plowing and the Columbine car for sowing.

Before the appearance of chain saw, the best tool to deal with this kind of thick trees was undoubtedly this kind of double lift big saw.

However, this kind of big saw is not an easy thing to play. The two people pulling the big saw must cooperate with each other and use their strength in a straight line and a horizontal plane as much as possible, otherwise it is easy to clip the saw.

The so-called clip saw refers to the uneven use of force in the process of moving the saw blade, which causes the saw blade to deviate from the plane of sawing, thus being clamped by the wood.

Clip sawing is the most taboo thing for carpenters when sawing wood. Because sawing is a work that pays attention to the sense of rhythm. Whether a person is good at sawing depends on his sense of rhythm.

The clip saw is the number one crime of destroying the sense of rhythm. Once the saw blade is clamped, it will destroy the sense of rhythm of the saw. The most important thing is that if the moment of clip saw is just when two people are exerting force, it is very likely that the saw blade will break.

Although the thickness of this big saw is close to 5 mm, don't forget that it's a two and a half meter long big saw with a very long arm. Both the cross saw and the wood planer brothers are strong adult men. When they pull the saw, once there is a clip saw, their force will be applied to the position of the clip saw through their long arm, so they are very likely to break the big saw.

However, the two brothers are worthy of being brothers. Although this is the first time to use a big saw to cut trees with real knives and guns, both of them remember the key to the sawing that the guardian told them in the early morning. In addition, they are both more careful. Even if they increase the pulling distance, they can still use the force as evenly as possible.

In order to prevent the clip saw, their saw speed will not be very fast. After pulling for more than ten minutes, the trunk of the whole tree could be cut by a fifth.

It's the best way to pull a large saw at the beginning, because the saw blade has not contacted with the sawn wood surface, so the friction is not very large. But with the deepening of saw teeth, the contact area between saw blade and wood surface will be larger and larger, and the friction will also be larger and larger, which will increase the load of sawing man.

Sure enough, after only pulling for more than ten minutes, the brothers gradually stopped pulling, and their arms were too sore to lift.

Sawing is definitely a kind of heavy physical work. Although it seems very easy for two people to pull each other, they actually use a lot of strength. Otherwise, how can they cut such a big tree.

The two brothers, the cross saw and the wood planer, are strong, but they can't stand it after only ten minutes.

But it doesn't matter if they can't stand it. Their sons immediately take over their respective fathers. The bow drill and chisel hold the handles at both ends of the big saw, and then they start to shout rhythmic numbers and continue to pull the big saw.

Obviously, the two brothers are not as skilled as their Laozi, but they are familiar with it. At the beginning, the two brothers were still a little careful, for fear of breaking the saw. But with the deepening of the saw teeth, the two brothers gradually came to know how to pull the saw, and the rhythm of the saw gradually became smooth.

So, under the gaping gaze of a large group of people, Mu Mu's two sons and two grandsons took turns to fight. In less than two hours, the tree fell to the ground with more than 20 soldiers shouting and pulling.

A group of people are like ghosts, even the soldiers who just pulled down the big oak tree are a little incredible.

In the past, more than ten people took turns to cut down such a big tree. At least it took two or three days to cut it down. But now, four people took turns to pull the big iron plate, and they fell the big tree in such a short time. This is really subverting the cognition of these people.

Old wood happily stroked the double lift big saw, even if the saw blade was still hot at this time, but old wood didn't care about it.

In fact, even old wood didn't believe that this big saw had such great power. He has a cross saw which is regarded as a treasure. His eldest son is named after that saw, which shows that old wood loves saw.

But even so, he never thought that the big saw could cut down the tree so cleanly. It's not ordinary wood or board. It's a big tree with three people embracing!

Can such a powerful big saw not make old wood ecstatic?

Stone bear looks at the old wood. It is estimated that the old man will have to name his great grandson or great granddaughter "big saw".

When you think about a newborn baby who is called "big saw" by a group of people, the scene is also a bit drunk

After the big oak tree fell to the ground, the people began to get busy after a short shock.

It's a big event for the tribe to cut down such a big tree. After all, there are too many parts for such a big tree. Even the thinner branches can make many spears. As for the thick trunks, they can be used to make bows and arrows after being dried in the sun. Oak is a good material for bows and arrows.

In particular, the oak is relatively hard, which can be used to make a hard bow. The range can be longer, and the power of the bow and arrow will be greater.

Of course, oak is also very good for making wooden bowls and basins.

In a word, every family in the tribe can benefit from the felling of this big tree.

So the people of the ethnic group rushed up in a crowd, chopping the branches and removing the bark. Needless to say, they cooperated very well. Even some little guys would pull some twigs aside.

Soon, the big tree was stripped "naked", the crown that could cover hundreds of square meters disappeared, the old bark that represents the vicissitudes of time also disappeared, so a big oak tree became a bare three meter long trunk.

But it's also a headache for the stone bear. The diameter at breast height of the remaining trunk is 1.4 meters, and the length is almost 3.5 meters, which is in line with the requirements of the stone bear.

But the problem is that the tree trunk is at least more than five square meters. Even if the proportion of the tree is slightly smaller than that of water, it can be converted into weight. The tree trunk alone is more than five tons, more than ten thousand jin!

How to get this big guy off the hillside?
