Abel plans to use this time to strengthen his strength. First of all, in terms of weapons. In this battle, if he has a long-range weapon, he can attack the werewolf from a distance, and he can also block the werewolf's approach from a distance. At least he can Make the werewolf slow down.
Abel thought a lot about long-range weapons, and he also conducted research on bows and arrows in this world, but he even wanted to make the 70-pound compound bow he used on Earth.
The advantage of this compound bow is that with an 80% labor saving ratio, when you draw the bow to full draw, you only need 14 pounds of draw weight to keep the bow at full draw (70×(1-80% )=14), the user can divert energy away from drawing the bow and focus more on aiming and adjusting his posture.
Under the condition of 60% labor saving ratio, 28 pounds of pulling force is needed to maintain the full bow state. The energy storage of the bow will be more, and the arrow will often be shot faster.
In these two states, you can choose the labor-saving ratio on the bow by yourself, and adjust the high or low labor-saving ratio of the compound bow according to the actual situation.
Because of his strong mental strength, Abel now has a very deep memory of the past. He remembers the various components of the compound bow and the dimensions of the components very clearly.
A compound bow consists of a drop wheel, a power wheel, upper and lower bow arms, a bow grip, a bow arm base, a bow string slide, a bow string shock absorber, an arrow rest, a handle, a main string, a secondary string, a bow limb shock absorber, a string stopper, etc. It is composed of accessories such as arrow rest, arrow rest, sight, launcher, shock absorber, peep hole, wrist rope, etc., to form a complete modern compound bow.
Although the level of the current world is limited, the power that people in this world can exert is much stronger than that of humans on earth. At least Abel has never heard of anyone in the original world who can kill people and horses with one sword. Split in half, this is when Knight Marshall is only an intermediate knight. It is even more difficult for Abel to imagine what kind of power a more advanced knight would have.
And now Abel's strength is stronger than most people on the earth. He is only 13 years old now. Abel now estimates that his strength is over 400 pounds. As a fitness instructor on Earth, he could only draw a 70-pound compound bow, but could not draw a stronger compound bow.
Therefore, although the materials for compound bows cannot be found in this world, because the people in this world are stronger, especially from Abel's point of view, making the compound bow is for his own use and can be replaced by stronger materials. Don't worry about weight.
Abel drew all the components one by one, marked the dimensions, and considered what materials to use.
For the following wheel and the power wheel, Abel considered using bearings as the rotational support of the two wheels to reduce the friction coefficient during their movement and ensure their rotation accuracy. The two wheels were made of Bailian rough blanks.
Abel was not prepared to make the upper and lower bow arms himself, because it would be too time-consuming. His idea was very simple, to dismantle two heavy bows. The production of heavy bows takes a long time, and the materials are all the best. Abel knew that in the warehouse There are several 200-pound heavy-duty bows, which are the strongest bows in the castle. However, few people use these bows because there are not many people who can pull the bows. Only trainee professionals of level four or above can pull them. Open, but opening and aiming are two different things. After opening, the same force must be maintained for aiming, then the user's strength must reach more than 300 pounds, or even higher to ensure that the heavy bow has enough power.
So those heavy bows have been kept in the warehouse and rarely used. Only the weapon custodians in the warehouse perform some daily maintenance. Abel thought that if he took two heavy bows and took them apart, there would be a bow arm and two Bowstring.
Both the upper and lower limbs use the limb part of a heavy bow, and the limbs of two heavy bows are glued together to obtain a stronger limb than a heavy bow.
Shock absorbers, bow limb shock absorbers and string stops are all made of wood, and bow handles and arrow rests are made of rough blanks.
After Abel planned everything, he started making compound bows. He found two heavy bows from the warehouse and hired a bow maker. Abel himself was not confident in making a qualified bow. Because the bow arm is the main source of power of the compound bow and the guarantee of its power after the final bow is completed, Abel believes that it is better to find a professional than to slowly fail again and again.
The bow maker who was hired dismantled the two heavy bows with great pain, then cut them into the size required by Abel according to the drawings provided by Abel, and then used fish skin glue to glue the two bow arms together. The final product Abel was very satisfied.
As for the shock absorber, bow limb shock absorber and string stopper, Abel hired a carpenter, and under Abel's guidance, Abel's requirements were met.
Slowly, each component was almost ready, and the final bearing could only be made by Abel himself.
It can be said that bearings are the most important parts of mechanical equipment on the earth. They are very difficult to make. Bearings are composed of inner rings, balls, and outer rings. There are raceways between the inner and outer rings, and the balls are between the inner and outer rings. scroll between.
Abel first made the balls. It is very difficult to make the balls with current technology because there are no industrial machine tools. He made them all by hand. As a master blacksmith, Abel was not under pressure.
He first made a vernier caliper, and then slowly forged a small piece of iron with a hammer. After making it into a round shape, he continuously measured it with the caliper and then forged it. Abel did not expect that a standard spherical ball would cost It took so much time and half a day to make a small ball. When measured by the vernier caliper, this ball was completely spherical.
After completing the production of the first ball, Abel used a clay green sand mold method, using clay and an appropriate amount of water as the main binder of the molding sand, and used the first ball to make thirty balls. sand mold.
Each bearing only has 12 balls, but Abel planned to make more spares. He originally thought that the most troublesome thing would be to use charcoal to turn the iron into molten iron. After asking Master Bentham, he learned that there is a special natural fire-supporting additive in this world. If you want to turn iron into molten iron, you can easily turn iron into molten iron by adding these natural fire-supporting additives during the heating process.
Abel poured molten iron into thirty ball sand molds, waited for them to cool and took them out. After some polishing, he finally got perfect balls.
Based on 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 power, these fine forgings were successfully completed.
The next step is to combine the inner ring and outer ring with the balls. This is introduced in many physics lectures and documentaries. Abel took out some ice from the ice cellar, placed the inner ring in the ice, and then placed the outer ring in the ice cellar. In the furnace, after a while, due to the principle of thermal expansion and contraction, the inner ring, balls and outer ring can be stuck together in order. After the temperature is normal, the bearing Abel wants is made.
Press down to fix the bearing, the finished falling wheel and the power wheel, and install and shape it step by step. Finally, Abel made the world's first compound bow.
Since this kind of compound bow cannot be left empty, it was evening time, so Abel put the compound bow away.
Early the next morning, after playing with Hei Feng for a while, Abel found fifty arrows from the warehouse and went to the archery range to test the new bow. Because this compound bow was too weird, Abel took the archery range to Empty.
He took out the first arrow, stuck it on the arrow rest, and pulled the release lever hard. Abel never thought that the strength required by this bow was so great. The combined force of the two heavy bows definitely exceeded 400 pounds. Abel It took almost all of Bo's strength to pull the bow open. After it was fully opened, he felt that his effort was relieved and he could maintain the stretched position with less than 100 pounds of strength.
Abel aimed the sight at the fifty-meter archery target, pressed the trigger on the launcher lightly, and the bowstring rang lightly, and the arrow flew out. It hit a straight line in the air at a distance of 50 meters. The bullseye then continued to fly backwards after hitting a round hole in the bullseye, hitting the 30-meter guard wall behind it before falling to the ground.
The 50-meter archery target is already the farthest archery target in the castle. Although Abel tested the compound bow and found that there were no problems with firing and aiming, the longest shooting range was not tested.
Abel held the compound bow in his hand and looked at the round hole in the center of the target in front of him. Abel had never heard of a bow that flew in a straight line within at least 50 meters. This compound bow was already the most technologically advanced bow in the world.
