Here are the plans for the Paper Medieval Style Crossbow. download these and you can build your own Paper Medieval Style Crossbow by following the videos.
Homemade Paper Medieval Style Crossbow. The only items that I have used to make this are: Paper, Cardboard,Tape and Screws. Took me nearly about a month to make. Take a look at the pictures to get a rough idea on how I made the crossbow.
6. Made holes in the cardboard for the trigger an nut. Used sticks to hold trigger and nut. Added layers of cardboard for spacing between the 2 pieces of the stock and between the trigger and nut and the stock. Used a spring to add tension to the trigger. http://www.youtube.com/watch?v=gNVKxlbtH_w&feature=channel&list=UL
7. Covered all the sides with 10 layers of paper (except the top railing part). Top railing part was covered with 1 layer of paper. The sticks could not tolerate the pressure from the rubber bands and hence broke. So I used screws instead. http://www.youtube.com/watch?v=L6VZjapkMSY&feature=relmfu
8. The 'sight block' (1st image) was made by sticking layers and layers of cardboard together until it had the desired thickness. Then a slot was made over the sight block in order to hold the arrow holder.
The 'arrow holder' consists of a rectangular piece of 16 layers of paper with a curved/bent strip of 16 layers of paper. This bent strip holds the bolt/arrow down. The arrow holder can be fit on to the sight block by pushing it through the slot made over the sight block. http://www.youtube.com/watch?v=L6VZjapkMSY&feature=relmfu
9. The rails were made by sticking two strips of cardboard side-by-side over the railing part.These strips were then covered with one layer of paper. The bolt/arrow can slide smoothly over the railing and can fit through the gap made in the nut. http://www.youtube.com/watch?v=L6VZjapkMSY&feature=relmfu
The crossbow consists of three rubber bands per side and is quite strong. It can shoot straight up to a range of 15 feet. When the weapon was just made it was quite accurate.but now it can only hit an area within a radius of about 6-8 inches. I also have to say that this is the first weapon that I have built which has a curvy shape. This crossbow is called a Medieval Style Crossbow because it resembles the crossbows used in the medieval times. Except that my crossbow is made out of paper and is powered by rubber bands.
Homemade Paper Medieval Style Crossbow (Slingshot)
Thanks to Tacome1942 (You Tube) , I can make paper as hard as wood and making it is as simple as you can imagine. All you have to do is keep gluing layers and layers of paper. If you make a piece of 32 layers, it will be as hard as wood. This will be very useful in my projects. To learn how to make hard paper, click the link.
My Homemade Paper Pistol Crossbow. Made out of paper and cardboard. Why? because that's all I've got. The barrel portion is made of 9 rolls of paper stuck together with some cardboard in between to make the barrel a bit wider. The railing is made from 2 strips of cardboard parellel to each other. The handle was made by sticking layers and layers of cardboard together and scraping the edges to make the handle kind-of ruond. The sight block was made by making a box-like structure above the handle.The trigger was made by cutting pieces of cardboard in the right shape and sticking them together. One very important thing is that the crossbow is powered by rubberbands, so you can call it a crossbow slingshot if you want. Last but not least I want to thank Joerg Sprave (from The Sligshot Channel), Weapon Collector and Jason Wemp (all from YouTube) for giving me ideas on making my crossbows.
