No One Understands Upgrades Better Than I Do

Author "No one understands eunuchs better than me"

It's very well written. Good luck to the author.

I won't say much else about the bow with empty strings. The reason why these bows cannot be empty strings is because the mechanical engineers who designed the compound bows did not consider empty strings at all when designing. Not all bows cannot be idle. Generally speaking, only those high-end bows cannot be idle. A low-end homemade bow can hold a lot of empty positions. Why can't high-end bows be placed empty? Because high-end bows are built for the ultimate in efficiency and precision. In order to ensure accuracy, bowstring materials can only be made of materials that are almost non-stretchable and not easy to plastically deform, so their ability to absorb shock and vibration is very poor. In order to prevent energy from being wasted on the bowstring, the bowstring cannot be very thick, heavy, or stretched and deformed. It can only be made from a handful of existing materials, and there is not much safety factor. In order to reduce excessive waste of energy on the eccentric pulley, the wheel must be made very light, thin, and hollow, and can only barely support the strength of normal archery. Otherwise, the energy that should be added to the arrow is eaten up by the wheel. In order to reduce energy loss and improve the energy storage conversion rate, the limbs must be made of materials with small damping and no plastic deformation. In order to increase speed, you cannot use materials that are too heavy (such as spring steel), but can only use things like fiberglass laminates and carbon fiber laminates, which are extremely easy to peel and break between layers. Although in theory you can use a special braided structure to increase strength, the cost is too high. After all, bows are products with extremely low sales. Unlike large-scale products such as plywood floor tiles, which are suitable for mass production with automated machines, the total output of all bow limbs in the world is less than one hundred thousandth of the total consumption of epoxy resin fiberglass materials. There will be no economies of scale at all, unless one day everyone's living standards are high and everyone has more than a dozen bows in their homes. For the sake of accuracy, thick rubber gaskets are not added to the connections between the bow limbs and other components. Laminated fiberglass laminates with screw holes drilled into them are inherently more susceptible to breakage. Even the handles are mostly hollowed out to reduce weight. Especially the cast handles made by some cheap workshops recycle a lot of old materials and have a lot of impurities, and they are reluctant to use expensive die-casting, low-pressure casting, and vacuum casting. As a result, the resulting castings have bubbles, inclusions, shrinkage porosity, shrinkage holes, and cold cracks and hot cracks that are invisible to the naked eye. When left empty, they can actually crack. As for the extremely fragile wheels, they cannot withstand idle vibrations. If they are slightly deformed, the symmetry and smoothness will be lost. Once deformed, a bow worth 10,000 yuan may not be as good as a domestic product worth 500 yuan. The bearings of some high-end compound bows are roller bearings. After being impacted several times, the rollers of the bearing will deform and the accuracy will decrease, so they must be replaced. But generally you can't tell it unless you take it apart. Even if the string is not broken at that time, some silk fibers will be broken inside. You can't see it from the outside. You don't know when something will happen suddenly. If the requirements are not so high, it is still easy to lower the requirements slightly and build a compound bow that can definitely be placed without damage. For example, use spring steel to forge a structure that integrates the handle and the spring leaf. It uses sliding bearings and is padded with thick pads such as polytetrafluoroethylene or polyformaldehyde. The wheels should also be made stronger and should not be hollowed out too much. Add a few reinforcement ribs in the thickness direction, and then create a buffering and energy-absorbing structure for empty rebound. With this kind of bow, you can play it in the air as much as you want. You can air it a thousand times or ten thousand times, or even a million times. It's just that this bow is relatively heavy, more than twice as heavy as an ordinary bow. This bow is not fast enough either, with the maximum arrow speed not exceeding 250fps. The accuracy will also be slightly worse. A bow like this can probably only be sold to amateurs. For those archery enthusiasts out there, just remember one rule: don't shoot empty. They had access to bows that were light, fast, and accurate, so it didn't matter to them that they were allowed to shoot empty. So, mechanical engineers did not design bows that allowed them to be released casually. Most of the time, bows are easily injured only when the load is high. If you reduce the strength, adjust a 20-70 pound entry-level bow to 20 pounds, and occasionally empty it a few times, it really doesn't matter, and there is no need to make a fuss. Actually, I think many people overestimate the dangers of empty bows. Archery is the safest sport in the world, with few injuries. Even if the entire bow breaks when you pull the bow, it is usually just a minor trauma. There is no need to be so sissy. How many bows have been broken since ancient times? Which hunter or soldier would regard this as dangerous? If you are not careful during hunting, you will die. If the bow is broken a thousand times, the probability of being killed by the bow is close to zero. So, only you effeminate urban middle-class pretty boys think it's a big deal if a bow string breaks or the blades of a domestic bow break. There will never be an accident like this in the factory. One-fifth of the stamping workers will be missing fingers or hands when they retire. They cherish this kind of job for the rest of their lives and are reluctant to resign. Although there are not too many examples of handles breaking due to empty storage, there are quite a few. For example, a domestic brand is famous for frequently breaking handles. In the circle of compound bow enthusiasts, CNC machined handles are generally favored because they are much more reliable than cast handles. Because aviation aluminum sheets such as 6·06 have high rolling pressure, the structure is very dense and there are few defects. Quality control of cast bows is difficult. In particular, the appearance of a compound bow is extremely important (because most people who play it are urban bourgeoisie and white-collar workers), so most of the design focus is on the appearance of the handle. Even some computer simulation designs mostly use finite element static stress analysis. If only this kind of analysis is done, any handle may have a safety factor of more than ten times - even the safety factor when it is idle. However, all the problems mainly arise from the casting process. When casting, there are many issues to consider. For example, due to different thicknesses, there will be differences in the solidification sequence. Thin areas solidify early, while in thick areas, the outer layer of skin solidifies first, and the liquid inside is replenished elsewhere, resulting in a lot of shrinkage cavities and shrinkage porosity. Since most castings are cast in metal molds, there is almost no concession (sand casting has certain concessions), which will lead to cold cracking and hot cracking caused by stress in many parts during casting. The average bow factory is a small workshop enterprise, which is not equipped with enough non-destructive testing equipment, and lacks mechanical engineers who understand casting technology. Therefore, most cast bow handles do have internal cracks that are not easily visible to the naked eye, and it is not surprising that they are broken by empty air. ——Casting a bow handle is much more difficult than using a CNC bow handle. If die casting is used, since the metal liquid is quickly filled under high pressure and solidified under high pressure, the shrinkage cavities and porosity will be much smaller. Even if there are bubbles inside, they will be compressed or dissolved into the metal under huge pressure, resulting in a dense structure. If there is no problem with the material itself, the quality of the die-casting product will be much better than that of atmospheric pressure casting. In addition, there are low pressure casting and vacuum negative pressure casting between die casting and normal pressure casting. The toe row compound bow produced by Gonglanglang uses die-casting technology for the handle. I have never heard of a short handle so far. As an entry-level bow, there should be many beginner users. There should be a lot of empty shots or misses, but it is not like the cast handle of a cheap brand that often breaks. Therefore, if the cast handle is at the level of the toe, it should be able to withstand emptying. ——Of course, this is only for the handle. The toe wheel is very thin and the limbs and strings simply cannot stand to be played empty. If the string is only unstrung when idle and there is no deformation of the wheel or cracking of the limbs, it should still be usable after re-stringing. If it is a domestic product such as a toe bow, the limbs are very cheap, the strings are also very cheap, and the wheels are also cheap. It only takes SF Express two days to buy an accessory. If it breaks, it is not a big deal. If it is an imported bow, you may have to wait three weeks, and then another three weeks for mailing and customs clearance. Of course, it may also take half a year. So, for a domestic entry-level bow, if you don't care about minor injuries, you basically don't have to worry too much about emptying it, or you may need to replace a few parts. The picture of the most serious injury I have ever seen was when the handle of the bow broke and hit his head, which resulted in dozens of cc of blood and several stitches. The skull was not broken, and there was no danger to life. The probability of just hitting the eye is not high. So, don't take the short position too seriously, especially if you use a cheap domestic bow. So some bows have the selling point of being able to be released occasionally. One of the famous marketing videos was scolded by many people for misleading beginners, and was eventually forced to be deleted. It was the air release video of Junxing's M106. Some people pointed out that it was fake because the poundage was not adjusted to a higher level, but was only air released at a low level. (If you use very light arrows in the high-pound setting, the damage effect on the bow is actually about the same as in the low-pound setting.) There are also some merchants who claim that their bows can be idle occasionally, such as the T1 of Apex. And it is guaranteed that even if its limbs are broken, they will not break and fly out. This may improve some security and trust for beginners. See for yourself, if you are dissatisfied, you can come.

Are you going to treat us like this? One chapter will be updated in 3 days during the National Day. Do you have genuine subscription support? Just this and this? What did you say in your request for leave? How long has it been on the shelves? Count your updates! Feel your conscience, are you worthy of the readers who support you? I don't want to scold you. If you continue like this, writing about dark and supernatural little lemons will be your end. If you write so well, it will be useless. If you perfunctory readers, you will only be disappointed in the end. Reflect on yourselves. Also, book friends, don't criticize me. I have been a bookworm for ten years. Give me some face and save my life🐶

This is my favorite book that I have read so far. Unfortunately, the update is a bit weak. I cry.

The author's writing is very good, there is nothing poisonous about it, the villain's IQ and EQ are generally normal, and the writing style is also good. It is considered to be the best among new books, but it is a bit short, and the pace is a bit slow and a bit dull. Some chapters are just about writing exercises. In fact, the exercises do not need to be introduced in too much detail. The early plot development is fine , after all, the protagonist's golden finger is very big, and he has to go outside to play his best role. The world is also big, and there is no need to spend too much ink on the novice village. What's more, the villain is a small character with three bosses and so on. The element of cultivating immortals should be added later. I hope the author will continue to work hard and not collapse. If you can't write about women, it is best not to have a female protagonist or an ambiguous partner. Just write more about the protagonist. K, you can create some big events. In addition, the protagonist can use the golden finger to strengthen some secrets, elixirs, etc., To win over subordinates and train the team. Xu Yong can be trained. After all, he has a good heart and will not betray. He can do something and seize the village. Of course, he can also leave. It depends on the author's ideas. That's it. I hope the author will continue to work hard. Thank you! Recommended votes for you!

This is the result of not saving the manuscript, typing in the middle of the night

The outline I made was 2.5 To 3 million words long, and eunuchs did not exist. I promise here, I don't dare to say anything else, but I will never be a eunuch. The performance of this book is not bad, and the outline is also very complete. At present, the development of the story is still in the novice stage, and I am just waiting for the major events in life to be completely completed. I will definitely not be a eunuch! ! ! Hahahahaha

I think the update speed is okay, one chapter a day. After all, he is not a professional writer. He has to support himself. He can't just rely on a new book that is not on the shelves, right? Please be considerate to the author😚

Books that have been ordered for five or six thousand are no longer written, and many great masters have achieved this level.
