This is the Black Widow Catapult. It was made by Pierre and my thanks go to him for sending the pic and information about it.

You can see that he used surgical tubing for the power source. It is a great way to go with a catapult.

This catapult is based on my Backyard Ogre catapult but Pierre made some terrific improvements. He has also been bitten by the siege engine bug and is already planning improvements to the next generation of the Black Widow Catapult!
