Chapter 200: "·Lenghuai Longbow"

Only when we try to understand a thing, will we have love and hate for him.
-Leonardo da Vinci (typical artist of the Renaissance)
After confirming that he wanted to make a simple and practical weapon of longbow in this world, Bai Feng first of all let the Simpson of the Governor's Guard lead the cavalry under his command to cut down trees for himself, and each kind of tree only Asked to cut down two tree trunks to bring back.
The Wendell Commander of the Governor’s Guard was also dispatched by Bai Feng. His mission was to recruit about 500 bow-making craftsmen for the city of Rome and build a new camp next to the Tassie camp, and bring all these attacks to the city of Rome. Come.
At the same time, Bai Feng also began to slowly write down the longbow making method in his memory in the governor's palace, preparing to let the recruited bow craftsmen make this longbow for the Roman city on a large scale. The method was brought to the outside world by Bai Feng.
The raw material should be a straight part in the middle of the trunk, with a uniform texture and no or as few knots as possible; cut most of the sapwood of the log to obtain a bow-back material with a cross-section of about four centimeters square, length and archer's body. See, to take the middle part, half of it is wooden heart and half is sapwood.
The wood core is relatively soft and resistant to compression, placed on the inside, and the hard and tensile sapwood is used as the outside; this can be judged by observing the wood grain of the cross section, the relatively sparse side is the outside.
By cutting the side of the wood core, the material is trimmed to be thick in the middle and thin at both ends, and then the two sides are slightly narrowed at the two ends, just like a pole, and the two ends are further trimmed into an octagon with a planer.
In the trimming, the surface must be flat, symmetrical at both ends, and uniform in thickness to achieve uniform force; after cutting out the shape, the elasticity of each segment of the bow should be checked by bending test.
Naturally grown wood is difficult to be uniform and uniform. Some places may be harder and some places softer. The uniform appearance may not be consistent; therefore, it should be corrected by observation to slightly thin the places with higher hardness. After the arch back is roughly adjusted, the string grooves can be filed at 5 cm at both ends. The outer side of the arch is deeper and the inner side is slightly shallower.
The most important process for making a bow is to bend it. The long bow has a simple arc shape, without the complicated shape of the Chinese corner bow; the British do not use fire roasting, which will reduce the tension of the bow; nor can it bend at once In place, in that case, the back of the bow will cause internal injuries and lose its elasticity even if it is not broken.
The process of bending is called "taming the bow", which means that the back of the bow gradually adapts to bending; to do this, a special bracket is needed. The bracket can be made of hardwood, and a groove is erected at one end to hold the back of the bow, and the other end Try to fix it vertically on the ground.
Eight to ten string grooves are etched at an equal distance of about four centimeters from the top to the bottom. The first string groove is about 20 centimeters from the head of the bracket. When the back of the bow is relaxed, the rope is tied to both ends. The center is placed on the groove of the bracket, with even force, slowly pulling the string, hanging into the first string slot, the back of the bow is slightly bent.
At this time, carefully check whether the curve of the back of the bow is smooth and even, mark the place that is too stiff, relax the back of the bow and adjust the trimming until it is satisfactory; then pull the rope away and increase the opening to hang down the groove , And continue to trim the back of the bow until a satisfactory uniform arc is formed, and each time you increase the opening of three or four chord slots, you can tighten the rope.
This process should not be rushed, especially before increasing the opening each time, it is best to allow the back of the bow to
rest
for about thirty minutes to release the internal stress to avoid wood damage; not to tighten too much every time, it is best Tighten one inch at a time.
When the full arch opening suitable for the archer is reached, the bow is tamed; here refers to the maximum opening that the archer can pull away, which is equivalent to the distance from the palm to the chest when the arm is extended out.
At this time, remove the bracket and brush the back of the bow with a few layers of linseed oil as a moisture-proof protective layer; when the oil is dry, you can hang the string. The bow string is made of sheep intestine or tendon. The elasticity and toughness are very good. .
The fixed opening degree when hanging the string is controlled by the distance between the bow string and the center of the back of the bow to reach the boxing height. Boxing height is the term in bow surgery, which is equivalent to the height of clenching fists and then raising the thumb, which is 15 centimeters larger. When tying the bowstring, make a special "shooter's knot" to avoid slipping.
The figure-shaped knot is simple but useful. The tighter the tension, the bow is made. You can measure the elasticity by hanging weights. The harder the bow, the longer the range, but the stronger the arm strength. The general long bow It takes about 50 kg of force to pull the full moon, and the strongest reaches 80 kg.
As long as there are sufficient materials, the longbow can be mass-produced as a standard weapon. It does not need to be tailored like a sword and armor. The archer can also use simple tools to make it, and does not rely on special equipment and craftsmen; and the cross The production of crossbows requires the skilled cooperation of multiple types of work and complicated equipment. It is simply impossible for barbarian bow craftsmen to build them.
After the five hundred bow craftsmen were brought to Rome by Wendel, Bai Feng first took the long bow making method he wrote, and explained to the craftsmen little by little; perhaps they did not understand Bai Feng's words very well. Words, but the specific approach is a piece of cake.
This is the advantage of dealing with professionals, you know they all understand, and they understand what you don’t understand; Bai Feng just dialed them a bit, and these senior craftsmen learned how to make the long bow that Bai Feng said .
After understanding the principle, the specific production is easy to handle; the tree trunks Simpson cut back with his soldiers are for the hands of the craftsmen. They must find the most suitable for making longbows while exploring the method of making longbows. wood.
The trees in this world are completely different from the trees on the earth. Bai Feng doesn't know what kind of trees are the most suitable for making long bows. Only these craftsmen can practice their hands while screening the trees that make long bows.
After nearly ten days of hard work, the craftsmen shared 37 trees and made 74 longbows that looked similar; Bai Feng then found some ordinary archers to test these longbows. See which tree has the longest range.
Facts have proved that there will always be something that surprises Bai Feng in this world of swords and magic. When more than 20 longbows have a range of less than 200 meters, a long tree made of a tree called Lenghuai The bow actually shot a range of more than 400 meters!
Bai Feng, who was shocked by excess joy, even personally experimented with it, and determined that the arrow shot by this cold locust longbow can penetrate the leather armor 350 meters away without using spiritual power; such a result simply makes Unbelievable!
The longbow made by other trees is more than the long bow of the cold locust, and the cold locust tree is an ordinary tree that can be seen everywhere on the barbaric ground. The large-scale cold locust longbow production in Rome City was opened. The prologue!
At this time, of all the legions in Rome, only the Cheetah Legion had thousands of archers. The other legions did not have archers. This is also related to the fighting style of the barbarian warriors; With regard to the power of the bow, Bai Feng also specially formed a new long archer force of 3,000 people outside the Cheetah Corps, which is temporarily under the jurisdiction of the Governor’s Guard.
