If I might add to BBSDaddy's suggestion....if you can find a piece of heavy copper wire like is used to ground home electrical boxes, instead of steel rod, you will save your hands and fingers from a beating. You can bend this easily in just the right places and then use it as a pattern for bending your final steel rod.
As he pointed out...you want to get it perfect as a jammed WOT is a nightmare!!! Hope this helps.
