Someone offered me a crossbow stock they had started on if I would complete the project. I dont have a ton of details yet, but apparently it was a kit at one time and most of the parts were lost as were the instructions. The thing is a 400# pull, using a leaf spring out of a car. Anyone have any idea where I would be able to find parts? |

Quoted:
400 lbs? That's not a crossbow, it's a ballista. Romans considered anything you couldn't pull back by yourself to be a form of artillery, even if you did it by yourself with a lever or a tool. A 400# pull would probably be considered a Scorpion or a light Ballistae. |

Quoted: Just about everyone bought a kit from a Kansas company to build a cross bow of around 100 pounds back when I was in high school. That's hard enough to cock, a 400 pound bow will require a winch. What can go wrong? Snap a string/wire and have the other end wrap itself around your neck?  Part of why I am looking for the original plans to even see if I want to complete it. |

Part of why I am looking for the original plans to even see if I want to complete it. I had a teacher in high school that owned a cross bow powered by a leaf spring. It was basic and had to be propped up to shoot due to weight. There are a few free plans floating around the internet for 100 pound class crossbows, but 400 pounds is a step up requiring good connections and hardware. A stock is barely a good start on this project; if you start sketching the rest of the parts needed, you'll see what I mean. |
