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

　　 Shixiong stood not far from the Hengsaw and Mucao brothers, humming softly the children's rhymes sung to him by his grandparents when he was a child.

　　 The double-handed saw is a weapon specially designed to deal with large trees, just like the ploughing of the sloping plow is used for plowing, and the chariot is used for planting.

　　Before the more powerful chain saw appeared, the best tool to deal with such thick trees was undoubtedly this double-handed big saw.

However, it is not easy to play with this kind of big saw. The two people who pull the big saw must cooperate tacitly, and the force used should be in a straight line and a horizontal plane as much as possible, otherwise it will be easy to appear. The situation of the clamp saw.

　　The so-called clamp saw refers to the uneven use of force during the movement of the saw blade, which causes the saw blade to deviate from the sawing plane, thereby being clamped by the wood.

　　 Clip saw is the most taboo thing for woodworkers when sawing wood. Because see-saw is a job that pays great attention to rhythm, a person's see-saw is good or not, just look at his rhythm.

Saw clamping is the number one crime that destroys the sense of rhythm. Once the saw blade is clamped and the rhythm of the see-saw is destroyed, the most important thing is that if two people are exerting force at the moment of clamping, it is very likely to be The saw blade was broken.

Don't look at the thickness of this big saw is close to five millimeters, but don't forget that this is a two and a half meters long saw with extremely long arms. Both the cross saw and the wood planer are both strong and strong. For adult men, once the saw is clamped when they are pulling the saw, their strength is added to the position of the clamped saw through the action of the long arm of force, then it is very likely that the big saw will be broken.

However, these two brothers deserve to be brothers. Although this is the first time to cut a tree with a real sword and a gun, both of them bear in mind the key to see-saw that Master Guardian has told me so early in the morning, plus Both of them are more careful, even if the pulling distance is increased, they still exert their force as evenly as possible.

　　 In order to prevent the saw pinch, their sawing speed will naturally not be fast. After pulling for more than ten minutes, the trunk of the entire tree could be sawed by a fifth.

　　 When pulling a large saw, it is best to pull at the beginning, because the saw blade has not yet contacted the sawn wood surface, so the friction is not very large. However, as the saw teeth continue to deepen, the contact area between the saw blade and the wood surface becomes larger and the friction force will become larger and larger, which will increase the load of the saw.

　　 Sure enough, only after pulling it for more than ten minutes, the brothers gradually stopped pulling, and the arms of the two of them were sour that they could not lift up.

Pulling a big saw is definitely a kind of heavy physical work. Don't look at the two people pulling and pulling it seems to be very easy, but in fact, the force used is very large, otherwise how could it be possible to saw such a big tree? .

　　 The two brothers Hengsaw and Musha 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 took over their father's class. The bow drill and chisel held the handles on both ends of the saw, and then began to shout rhythmic chants, and began to continue pulling the saw.

　　 The two brothers are obviously not as proficient in drawing a saw as their Lao Tzu, but this thing is familiar. At first, the little brothers were a little cautious, for fear of breaking the saw, but as the saw teeth continued to deepen, the little brothers gradually learned the trick of pulling the saw, and the rhythm of the saw gradually became smoother. stand up.

So, under the stunned gaze of a large group of people, Mu Mu’s two sons and two grandsons took turns in battle. It took less than two hours. The big tree shouted in unison among the twenty soldiers. Zisheng and vigorously pulled down and fell to the ground.

　　 A bunch of people are just like seeing a ghost, even the soldiers who just pulled down this big oak tree are a bit unbelievable.

Before using a stone axe to chop such a big tree, more than a dozen people would take turns to work at least two or three days to cut down, but now only four people take turns to pull that big piece of iron, it is so short. This big tree was destroyed within a short period of time, which is really subverting the cognition of these people.

　　 Old Wood happily stroked the double lift saw, even if the saw blade was still hot at this time, but Old Wood could take care of this.

　　 In fact, even Old Wood didn't believe that this big saw could be so powerful. He has a cross saw which is regarded as a treasure. His eldest son is named after that saw, which shows the old wood's love for saws.

　　 But even so, he never thought that this big saw could cut down this big tree so cleanly. This is no ordinary wood or plank, it is a big tree with three people hugging each other!

　　With such a powerful saw, can the old wood be ecstatic?

Shi Xiong looked at the look of Old Wood. It is estimated that this old guy might have to name his great grandson or great granddaughter who is about to be born "Da Saw"~lightnovelpub.net~ Think about a new born. Little Baby, called "Big Saw" by a group of people, was also a little drunk...

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

　　 The felling of such a big tree can be regarded as a major event in the tribe. After all, there are too many available parts for such a big tree, even the thinner branches can make many spears. As for those thick trunks, they can be used to make bows and arrows after being dried. Oak is a good material for bows or arrows.

　　Especially oak is harder and can be used to make hard bows. The range can be longer, and the power of bows and arrows will be greater.

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

　　 In short, this big tree is felled, and every family in the tribe can benefit from it.

　　 So the people of the tribe rushed up, cutting branches, cutting branches, and removing bark. Needless to say, they cooperated very well. Even some little guys will pull some twigs aside.

Soon, the big tree was stripped "naked", the canopy that could cover hundreds of square meters was gone, and the old bark that represented the vicissitudes of life was gone, and the huge oak tree became like that. The bare trunk is more than three meters long.

　　 But the things that caused Shixiong's headache also followed. The remaining trunk has a diameter at breast height of 1.4 meters and a length of almost 3.5 meters, which meets the requirements of the stone bear.

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

　　 How did you get this big guy off the hillside?
