Ballista 2009

A ballista is an ancient war machine. Originally the word ballista was used for what we know as a Roman stone-projecting catapult. My ballista would be in Ancient Greece called “oxybeles“. It has been built according to an old Greek formula from the third century BC. The maximum range is 122m (400ft). It shoots arrows that weight around 100g (1/4 lb) that are capable to pierce 3cm (1,2“) thick wood. I have built it with my friend in 2 weeks during my summer holiday in 2009. Please send comments. If you are at least a little bit interested in catapults, trebuchets and similar war machines, do not hesitate to contact me.
