Don't attempt makeshift torsion bars. I was cleening my Leek and right after my cats finished chasing each other hrough my room lo and behold the torsion bar is gone. Using a bike spoke I attempted to duplicate the rod/bar based off a google pic. Something wasn't quite right... It slipped from my hand, hit my knee opening it 2/3 of the way and then landed on my foot. I now have no big toenail and a missing chunk of skin. Oww... the older serrations are deadly! I just found the darn bar.
