Well you dont want to use old old rusty stuff if one can use newer stuff that has little rust that would be good. I start by cutting me a piece of good logging cable in about a 3 foot piece and heating it in the middle get a good heat on it then bend it in half. Heat it up some more and twist it up really tight then I heat in middle and repeat, you dont have to do this folding if your wanting to make smaller stuff, but in my case when I was making this spear i folded it one more time twisting it after every fold. Then weld it all together and make a bar of the whole stuf and there you are make what you need. I hope this helps man have fun.............. and it will make a wavy pattern it really deppends on how you twist it up.
