Who said making a Trebuchet has to be an all day project? This version took less than 2 hours to build and the results are great. The tennis ball flew 30′, which is fairly impressive. You should be able to get even better results some slight modifications.

The purpose of this project was to design and create a working model trebuchet – capable of launching tennis balls – and manufactured from scrap materials in as short a time as possible.

With that in mind, it’s not going to be a beautiful, efficient or durable machine, but hopefully it will still work…
