Thanks everyone for all the ideas! After searching around my house I found some wire with a solid strain of copper in it thats perfect for amsteel but JUST too big for the 1.75mm zing-it. I'm going to head to a music store on the way home today and get a high e guitar string and see if I have any better luck with that. I can tell this stuff is not going to be easy to splice. Even getting the wire into the zing-it
Is hard let alone pulling the folded over end through.
