Chapter 34

Abel is going to use this period of time to strengthen his strength. First of all, in terms of weapons, in this battle, if there is a long-range weapon, he can attack the werewolf from a long distance, or block the approach of the werewolf from a long distance, or at least slow down the speed of the werewolf.

Abel thought a lot about the long-range weapon, and he also studied the bow and arrow of the world, but he wanted to make the 70 pound composite bow that he used on the earth.

The advantage of this kind of composite bow is that in the case of 80% labor-saving ratio, when you pull the full bow, you only need 14 pounds of pulling force to keep the bow in the state of full bow (70 × (1-80%) = 14). Users can transfer their energy from the bow, so that their attention is more used to aim and adjust their posture.

With a 60% labor saving ratio, a 28 pound pull is needed to keep the bow full, the energy storage of the bow will be more, and the speed of the arrow will be faster.

These two states can choose the labor saving ratio on the bow body, and adjust the high or low labor saving ratio of the composite bow according to the actual situation.

Because of his strong mental power, Abel now has a deep memory of the past. He clearly remembers the components of the composite bow and the size of the components.

The composite bow is composed of falling wheel, power wheel, upper and lower bow arms, bow handle, bow arm seat, bow string slide sleeve, bow string shock absorber, arrow table, handle, main chord, auxiliary chord, bow slice shock absorber, string stopper, etc. in addition to the accessory arrow seat, arrow table, sight device, hair dispenser, shock absorber, peephole, wrist rope, etc., a complete modern composite bow is formed.

Although the current level of the world is limited, the power that people in this world can play is much stronger than that of human beings on the earth. At least Abel has never heard of anyone in the original world who can split people, people and horses into two parts with one sword. This is what kind of power a higher Knight would have if Marshall knight was only an intermediate knight, Abel is more unimaginable.

Now Abel is more powerful than most people on earth. He is only 13 years old. Abel now estimates that his strength is more than 400 pounds. Like on earth, as a fitness coach, he can only pull 70 pounds of composite bow. The stronger composite bow can't be pulled.

So although the material of composite bow can not be found in this world, but because the strength of people in this world is stronger, especially from Abel's own point of view, making composite bow is his own use, it can be replaced with more solid materials, without considering the weight problem.

Abel mapped and dimensioned all the components and considered what kind of materials to use.

In order to reduce the friction coefficient and ensure the rotation accuracy of the two wheels, the bearing is used as the rotation support of the two wheels. The two wheels are made of rough blanks.

Abel is not prepared to make the upper and lower bow arms by himself, because it takes too much time. His idea is very simple. It takes a long time to dismantle two heavy bows. They are made of the best materials. Abel knows that there are several 200 pound heavy bows in the warehouse, which are the strongest bows in the castle. But few people use those bows, because there are not many people who can pull them apart There are four or more apprentices who can pull away, but pulling away and aiming are two different things. After pulling away, they need to maintain the same force to aim. Then the user's strength must be more than 300 pounds, or even higher, to ensure the use of heavy bow has more force.

So those heavy bows have always been put in the warehouse and few people use them. Only the weapons keeper in the warehouse carries out some daily maintenance. Abel thought that if he took two heavy bows apart, he would have a bow arm and two bowstrings.

The upper arm and the lower arm use the arm part of the heavy bow, and the arms of the two heavy bows are bonded together, so that the arm with stronger specific gravity bow can be obtained.

Like shock absorbers, bow shock absorbers and string stoppers, these are made of wood. Bow handles and arrow stands are made of rough blanks.

After Abel had planned everything, he began to make composite bows. Two heavy bows were found out of the warehouse by Abel, and a bow maker was found. Abel himself was not confident to make a qualified bow arm, because the bow arm is the main source of strength for composite bows, and it is also the guarantee of the power of the final bow. Abel believed that the professional would be better than himself It's much better to fail over and over again.

The bowmaker painfully removed two heavy bows, then cut them into the size required by Abel according to the drawings provided by Abel, and then glue the two bowarms together with fish skin glue. The final product made Abel very satisfied.

As for the shock absorbers, bow shock absorbers and string stoppers, Abel found carpenters and met Abel's requirements under Abel's guidance.

Slowly, the parts are almost ready, and the final bearing can only be made by Abel himself.

It can be said that the bearing is the most important part of the mechanical equipment on the earth, which is very difficult to make. The bearing is composed of inner ring, ball and outer ring. There is a raceway between the inner ring and outer ring, while the ball rolls between the inner ring and outer ring.

Abel is the first to make balls. It's very difficult to make balls with the current technology, because there is no industrial machine tool, all of which are made by hand. As a master blacksmith, Abel has no pressure.He first made a vernier caliper, and then slowly forged small pieces of iron with a hammer. After making them into a circle, he constantly measured them with a caliper, and then forged them. Abel didn't expect that a standard ball like ball would take so much time. In half a day, he made a small ball. In the measurement of vernier caliper, the ball was completely a ball.

After the first ball was made, Abel used a kind of clay wet sand mold method, with clay and appropriate amount of water as the main binder of molding sand, the first ball was made into 30 ball sand mold.

Only 12 balls are needed for each bearing, but Abel is going to make more spare parts. He thought that the most troublesome thing is to turn iron into molten iron with charcoal. Only after asking master Bentham did he know that there is a special kind of natural fire aid additive in the world. If he wants to turn iron into molten iron, he can easily turn iron into molten iron by putting these natural fire aid additives in the heating process.

Abel poured molten iron into 30 ball sand molds, waited for the cooling to take out, and after some grinding, finally got the perfect ball.

According to the size of the ball, Abel calculated the size of the inner and outer rings, as well as the depth of the raceway. With the help of Abel's mental force, these fine forging was successfully completed.

The next step is to combine the inner ring and outer ring with the ball. This was introduced in many physics lectures and documentaries. Abe took some ice out of the ice cellar, put the inner ring in the ice, and then put the outer ring in the furnace. After a while, due to the principle of heat expansion and cold contraction, the inner ring, the ball and the outer ring can be stuck together in order. After the temperature is normal, he will make it The bearings Abel wanted.

Press it down to fix the bearing, the falling wheel and the power wheel, and then install them step by step. Finally, Abel made the first composite bow in the world.

Because the composite bow can't be released, it's evening time now. Abel has put the composite bow away.

The next morning, he played with Heifeng for a while. Abel found fifty arrows from the warehouse and went to the archery to test the new bow. Because the composite bow was so strange, Abel emptied the archery.

The first arrow was taken out, stuck on the platform and pulled the dispenser. Abel had never thought that the strength required by the bow was so great. The strength of the two heavy bows was definitely more than 400 pounds. Abel almost used his whole body's strength to pull the bow apart. When he pulled the bow apart completely, he felt that it would save him a lot of effort, as long as it took less than 100 yuan With a pound of force, you can hold the pull away position.

Abel aimed the collimation center of the sight at the target of 50 meters, pressed the trigger of the dispenser lightly, and the arrow flew out with a slight ring of the bowstring. The 50 meters distance in the air hit the bull's center in a straight line, and then after hitting a round hole in the bull's center, he continued to fly back and hit the protective wall of 30 meters behind until he fell to the ground.

The 50 meter target has been the farthest target in the castle. Although Abel has tested the launching and aiming of the composite bow, the farthest range has not been tested.

Abel is holding the composite bow, looking at the round hole in the center of the target in front. Abel has never heard of the straight-line arrow flying within 50 meters at least. This composite bow is the most advanced bow in the world.
