Hi All,
I've dumped the crummy wire and I now use straight pins. I usually have to drill out the links beforehand (takes about and hour) with my dremel. Then, insert the pins, cut off the ends and voila! The friction of the pin and the link hold everything together nice and tight. Also, you can select the right size head and diameter of the pin and they are readily available: walmart's craft/sewing area. HTH.
Regards,
Georg
