![]() The weapon used by the ancient militaries was developed into a composite-recurve variety for more power. ![]() Such action could fire 10 bolts in 15 seconds, after which the magazine would be reloaded. The bolts of one magazine are fired and reloaded by simply pushing and pulling the lever back and forth. Other repeating crossbows fired as many as 10 bolts before exhausting the magazine. Zhuge Liang improved the design of the repeating crossbow, and made a version which shot two to three bolts at once and was used in massed formations. Also known as the lián nǔ ( simplified Chinese: 连弩 traditional Chinese: 連弩 literally "continuous crossbow"), the invention is commonly attributed to the strategist Zhuge Liang (181–234 AD) of the Three Kingdoms period, but those found in Tomb 47 at Qinjiazui, Hubei Province have been dated to the 4th century BC. The Chinese repeating crossbow ( Chinese: 諸葛弩 pinyin: zhūgě nǔ Wade–Giles: chu-ke nu literally "Zhuge crossbow" sometimes romanized as "chu-ko-nu") is a device with a simple design. Ok, that’s not properly modelling.Chinese repeating crossbow (non-recurve version ones used for war would be recurved) ![]() Who could ask for more? Well… ME! I wanted a video, and i did it! Today the crossbow had the first debut in the lab, and all my colleagues played with it. Mainly, i had to add a small wooden piece on the back of the magazine to prevent the arrows to slide behind when loading, and i had to sand all the critical surfaces to have a smoother movement. I had to try the crossbow several times (many, really) and tweak a few minor issues. You can see that there are two small beam on the front to guide the moving part in the right direction, preventing trasversal deviations. Once placed the arrow magazine, the crossbow looked like this: The rest of the beam on the bottom is very important, because it will push the whole piece down, releasing the rope and shooting the arrow. Behind that there’s a gap for the bow rope. However, that is what i have: the frontal part has a smaller railing to keep the arrow (in this case, a matchstick) in position. If i had to make a second repeating crossbow (and i will), i would have added the magazine from the beginning. Note that the “arrows magazine” is still not in position. Let’s take a closer look to the moving part in the center. After the glue was dry, they were a single piece. To prevent the two beams of the loading mechanism to move indipendently, i blocked them on both sides. The central moving part is visible in the photo, and has a gap where the rope will remain blocked turing the loading. Using a metal rod obtained from a paperclip i fixed the two joints of the loading mechanism. Note that for the whole project i didn’t use any ruler. I used two sticks to make the beaming, taking the measurements before cutting them in shape. The recharging mechanism is really similar to the one shown in the ancient illustration. Now the crossbow shape is clrealry visible. I removed part of the rail, where the grip will be, then i glued the bow on the tip of the body. On the back side, i cleaned the irregularities with a cutter, then i finely sanded the surface to have a smooth finish. I glued on the sides another two sticks, this time a little elevated to create a rail. It took only 10 minutes to have a solid structure. Meanwhile, for the body of the crossbow i used some popcicle sticks glued together, kept under pressure until dry. For the rest of the construction i used only PVA glue. I used two rectangular hairpins (i’m not sure that’s the right term for those) for the flexible parts, glued together with some cyanacrilic. I wanted do build something more challenging, and i stumbled across this picture.įrom that moment i couldn’t think of anything else, i WANTED a repeating crossbow, and even though the picture was decades (or centuries?) old, that was clear enough to start building something.įirst of all, i needed the bow. The result was a bigger crossbow with trigger, meant as a gift for a friend.īut it wasn’t enough. The result was fairly simple but really appealing, and made me want making one. The other day i saw an amazing and inspiring video about making crossbow with hairpins, popcicle sticks and a short rope.
