You could use the twine used for kite strings. I've got a ballista (a twin-spring torsion engine) that uses that stuff. It works pretty well.

This looks pretty simple yet powerful. I'd love to make this for my boys - do you have a step by step?

Looks like a simple, but effective design. What did you use for the skein?

I love to make and build things, especially duct tape things, catapults and secret stashes. I can do a little work with electronics, and I am a slight pyrotechnic as well.
