If you have spent any time searching for free plans, you probably noticed that there are plenty to choose from. Some are free plans and some you have to pay for. If you go with the free plans, you will find that a lot of free plans are lacking in terms, leaving a lot to figure out for themselves.
Most of the free plans have no way that you can customize the plans for your own use. They typically can only be built the exact way the plans call out for them, or else they will be unstable and perhaps will not last very long.

The early history of the catapult and the crossbow in Greece is not that far apart. The weapon was soon after employed against motya, a key Carthaginian stronghold in Sicily. The date of the introduction of crossbows, however, can be dated further back, according to the inventor Hero of Alexandria, who referred to the now lost works of the 3rd century BC engineer Ctesibius, this weapon was inspired by an earlier hand held crossbow, called the gastraphetes, which could store more energy than the Greek bows. A detailed description of the gastraphetes, along with a drawing, is found in Heron technical treatise Belopoeica.
The last large scale military use of catapults was during the trench warfare of world war I. during the early stages of the war, catapults were used to throw hand grenades across no man land into enemy trenches. These were eventually replaced by small mortars.
Special variants called aircraft catapults are used to launch planes from land bases and sea carriers when the takeoff runway is too short for a powered takeoff or simply impractical to extend.
