Re: looking for a torsion spring
 

Many different companies make torsion springs. I was able to pull up 176 springs from http://www.mcmaster.com and I know small parts also offers torsion springs. Of course, you could always make your own out of rope like in catapults, but either of these two sites would hopefully have what you are looking for.

Also- try http://www.mscdirect they are another industrial supplier
