I bought a piece of steel from lowes, I think it's like 8x4 inches. Think it was like 8 bucks. I drilled a hole in the middle top edge. I hang mine from an old cleaning rod I bent up. But the more fun thing to do is to hang them from a rope off the bottom of a saw horse or something. That way when you hit them they spin.
Never give in, never, in nothing great or small, large or petty, never give in except to convictions of honour and good sense. Never yield to force; never yield to the apparently overwhelming might of the enemy. - Winston Churchill
