MTL - Abe the Wizard

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

Abel thought a lot about long-range weapons, and the world ’s bow and arrow Abel also studied, but he wanted to make a 70-pound composite bow that he had used on Earth.

The advantage of this compound bow is that under the condition 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 full state (70 × (1-80%) ) = 14), users can divert their energy from pulling bows, so that they can focus more on aiming and adjusting their posture.

At a 60% labor saving ratio, a 28-pound pull force is required to maintain a full bow. The bow will store more energy, and the arrow will often shoot 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 compound bow according to the actual situation.

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

The compound bow consists of the falling wheel, the power wheel, the upper and lower bow arms, the bow handle, the bow arm seat, the bow string sliding sleeve, the bow string shock absorber, the arrow table, the handle, the main string, the auxiliary string, the bow damper, the stopper and other parts The composition, plus the attachment arrow stand, arrow stand, sight, hair spreader, shock absorber, peephole, wrist rope, etc., form a complete modern composite bow.

Although the level of this world is limited, the people in this world can exert much more power than the humans on the earth. At least Abel has never heard of anyone in the world who can lead people to horses with a sword. Split in half. This is still the case when the Marshall Knight is only an intermediate knight. If a more advanced knight would have any power, Abel is hard to imagine.

Now Abel's power is stronger than that of most people on the earth. He is now only 13 years old. Abel now estimates that his strength is about 400 pounds or more. As on the earth, as a fitness instructor, he can only pull a 70-pound composite bow. A stronger compound bow cannot be pulled.

So although the material for composite bows can't be found in this world, but because people in this world are more powerful, especially from Abel himself, making composite bows is for his own use, and it can be replaced with stronger materials. Don't worry about weight.

Abel drew all components in the same way, dimensioned them, and considered what materials to use.

With wheels and power wheels, Abel considered the use of bearings to support the rotation of the two wheels to reduce the friction coefficient in the process of movement and ensure the accuracy of their rotation. The two wheels were made of Bailian rough.

Aber did n’t plan to do it on his own, because it was too time-consuming, his idea was simple, to dismantle two heavy bows, the production of heavy bows took a long time, and the materials were the best. Abel knew that in the warehouse There are a few 200-pound heavy bows, the strongest bows in the castle, but those bows are rarely used, because not many people can pull that bow, only trainees above level 4 can pull it. Open, but pulling and aiming are two different things. After pulling apart, keep the same force for aiming, then the user's power must reach 300 pounds or more, to ensure that the heavy bow has enough power.

So those heavy bows have been kept in the warehouse rarely used. Only the weapon custodian in the warehouse performs some daily maintenance. Abel thought that if two heavy bows were taken apart, there would be a bow arm and two Bowstring.

Both the upper and lower bow arms use the bow arm portion of the heavy bow, and the two bow arms are glued together to obtain a stronger bow arm than the heavy bow.

Like shock absorbers, bow dampers and chord stoppers, these are all made of wood, and bow handles and arrow rests are made from rough rough.

After Abel planned everything, he began to make a compound bow. Two heavy bows were found by Abel from the warehouse, and a bowsmith was found. Abel himself was not confident to make a qualified bow. Arm, because the bow arm is the main source of strength for the compound bow, and it is the guarantee of the power that can be exerted after the bow is finally formed. Abel believes that finding a professional is always better than failing slowly and repeatedly.

The found bowsmith removed the two heavy bows with great pains, then cut them to the size required by Abel according to the drawings provided by Abel, and then glued the two arms with fish skin glue. The final product Make Abel very satisfied.

As for the shock absorber, bow damper and chord stopper, Abel brought in a carpenter, and under Able's guidance, he also met Abel's requirements.

Slowly, every piece of accessories has been prepared, 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, and the production is very difficult. The bearing consists of an inner ring, a ball, and an outer ring. There is a raceway between the inner ring and the outer ring. The ball is on the inner and outer ring. Scroll between.

Abel first made balls. It is very difficult to make **** with current technology. Because there is no industrial machine tool, all are made in hand. Abel, a master blacksmith, is not under pressure.

He first made a vernier caliper, then slowly forged a small piece of iron with a hammer. After making it into a circle, he continued to measure with a caliper, and then forged. Abel did not expect that a standard spherical ball would cost In so many hours, a small ball was made for a full half day. This ball is completely spherical in the measurement of vernier calipers.

After completing the production of the first ball, Abel used a clay wet sand mold mold method, using clay and a suitable amount of water as the main binder for the sand, and made the first ball with thirty balls. sand mold.

There are only 12 **** per bearing, but Abel is going to make some spares. The original thought was that the most troublesome was to turn charcoal into iron. After asking Master Bensham, I knew that there was a special natural fire additive in the world. If you want to turn iron into molten iron, you can easily turn iron into molten iron by adding these natural fire-assist additives in the heating process.

Abel poured the molten iron into thirty ball sand molds, waited for cooling and took it out, then polished it, and finally got the perfect ball.

Based on the size of the ball, Abel calculated the size of the inner and outer rings, and the depth of the raceway. These fine forgings were successfully completed with the help of Abel's mental power.

The next step is to combine the inner ring and the outer ring with the balls. This is introduced in many physics lectures and documentaries. Abel took some ice from the ice cellar, put the inner ring in the ice, and then put the outer ring into the After a while in the stove, due to the principle of thermal expansion and contraction, the inner ring, ball and outer ring can be locked together in order. After the temperature is normal, Abel's desired bearing is made.

Press down to fix the bearing and the completed fall wheel and power wheel, and install it step by step. In the end, Abel made the world's first compound bow.

Since the compound bow could not be left empty, it was evening time, and Abel put away the compound bow.

Early the next morning, playing with Black Wind for a while, Abel found fifty arrows from the warehouse and came to the archery range to test the new bow. Because this compound bow was too weird, Abel took the archery range. Empty.

The first arrow was taken out, stuck on the arrow stand, and pulled the spreader hard. Abel never expected that the power required by this bow would be so great. The combined force of the two heavy bows was definitely more than 400 pounds. Bo almost exhausted his whole body to barely pull the bow away. After it was fully pulled out, he felt like he had no effort at all. As long as he spent less than 100 pounds of force, he could maintain the opened position.

Abel aimed the sight of the sight on the fifty-meter arrow target, and lightly pressed the trigger on the spreader, and the bow struck softly, and the arrow flew out. The distance of 50 meters in the air was completely straight. The bull's eye, and then after the bull's eye hit a round hole, it continued to fly backwards, hitting a 30-meter wall behind it, and then fell to the ground.

The 50-meter target is already the farthest target in the castle. Although Abel has tested the launch and targeting of the compound bow without any problems, the longest range is not tested.

Abel was holding a compound bow, looking at the round hole in the center of the arrow target in front. Aber, who flew straight within a minimum of 50 meters, has never heard of this compound bow. This compound bow is already the most technologically advanced bow in the world.
