What is a Petraria Arcatinus? Roughly translated, it means "Bow powered rock hurler". There has been much debate over whether these machines actually existed or not. There is very little in the historical record to suggest a machine like this, but there are a lot of artists drawings from ancient times depicting bow powered, spoon armed machines.
We built a lot of machines based on those drawings, and they usually didn't work worth beans. But, taking what we learned and committing to creating a bow-powered catapult that really works, we eventually discovered this design.
This elegant little machine is highly versatile. Capable of hurling just about anything ranging in size and weight from marbles to baseballs. We were able to hurl golf balls about 50 feet, and baseballs sailed nearly 20 feet! Powered by a bow with a 50 pound pull, this little machine is only 18 inches long and 10 inches wide. The arm reaches 18 inches high at rest.
