I've heard of people making them out of Weedeater line but haven't tried it myself. Sounds like it would work. I think all you do is to figure out where you can drill some holes and put the line in and glue it with CA. Other than that you can also make them out of thin music wire or simular and use electrical fittings (wire lugs) on the ends to put a bolt through the lug and stab. You can solder the lugs on or glue them on with JB Weld.
