Hi Mike, 5mm piano Wire will also do the trick, but drill holes in it becomes a little difficult, but Like I say you can do it with a Dremel and a Tungsten Carbide bit. Just get the rev's right and the Bit will reach the right temperature and go through like a hot knife in butter, I can draw up the arrangement in AutoCad if you would like, it shouldn't take too long, but the Pictures show all the information too.
