![]() In view of the structures, the development of the original crossbow can be divided into Unearthed trigger mechanism was found in Qufu in Shandong Province, and it can be dated back to the 6th century BC (Zhong, 2008). The original crossbow is The Art of War dated from 498 BC (Needham, 1954). In the Warring States Period (475–221 BC), it There are a lot of ancient documents which recorded informationĪbout the original crossbow. In the Spring–Autumn Period (770–476 BC), the original crossbow had been widely used. WesternĬrossbows are often complex, and several moving parts must have been fabricated. The characteristics of Chinese crossbows are that the parts are easy to re-assemble and are exchangeable. Around the 16th century AD, it spread to Africa and the Americas. Of Eurasia, and more Asian than European. The crossbow is fundamentally an implement of warfare ![]() Long periods of time and being inaccurate in shooting (Zhang et al., 2004 Human force, thus remedying the two issues of people being unable to aim for This development improved the bowstring which previously had to be pulled by Tightened the bowstring, it facilitated the aiming and shooting of arrows. Trigger mechanism onto a traditional bow. It was developed by adding the frame and a This could beĭescribed as a developed weapon which used the delayed force of the bow'sīowstring to shoot arrows. In ancient times, an original crossbow was called a “nu”. People's interest in hunting implements continued to develop over the nextįew thousand years, and this influenced the development of human projectile Progressed from throwing stones to using bows and arrows in hunting. Therefore, it is widely believed that prehistoric people's behavior Many arrowheads have been excavated which are made from stones or animalīones. In addition, in ruins dating back to the Neolithic Age, In ruins, stoneĪrrowheads have been unearthed, dating from 1.7 million years ago to 10 000 years ago. The original crossbow evolved from the traditional bow. Two crossbows are presented to illustrate the shooting processes. Proposed to check the constrained motion. The degrees of freedom of two crossbows are Then, topological structures of the original crossbow and Chu State Provided as an example to describe the manufacturing process of the bow. A brief history of the development of the crossbow in ancient China is given. Matrix to present the topological structures of the original crossbow and It is defined as a reconfigurable mechanism. Of the crossbow has a different configuration during the shooting process, After the 4th century BC, the technology of producing crossbows was very sophisticated. Because it used theĮlasticity of the bow and the bowstring to shoot arrows, it was used for It was one of the most frequently used weapons during theĥth century BC to the 18th century AD. I have therefore removed the incomplete PDF documents, leaving only the complete PDF originally provided by user El Supremo.In ancient China, people integrated the original bow, theīowstring, and a cam mechanism to develop a powerful weapon which was named I have also looked back at the original book I scanned this from, and realized (thanks to a commenter) that I managed to skip two pages of the original article in my scans. Links have been removed, as they no longer work. UPDATE 11/22/17 - It's been a good while since I've looked at this page. ![]() Many thanks for this high quality download! This PDF is also available as a download from the Instructable. ![]() Also, thanks to El Supremo for providing an alternate download from 4shared (link removed). However, since I see no reason to take it down, the wiki will remain live for anyone who wishes to download or view the files that way. I've updated the Instructable slightly and moved the location of the PDF files from the previous wiki to the Instructable itself. UPDATE 7/26/13 - Two years and 13,000 views later, I've finally realized that these plans are somewhat popular. None of them are perfect, and the best one is turned sideways. I made a few PDF files of this, and you can find them at (link removed). Anyway, I just thought this might help some of you people wanting to build a crossbow! :) The metal on the front of the smaller crossbow could be replaced with something else, such as a thick strip of plastic. Some of it is outdated, but I'm sure there is a way to fix that. These are some old DIY crossbow plans from the 1945 edition of "The Boy Mechanic".
