While looking for something to use as decorative gold bezel trim, i
had an idea. I wanted something delicate, yet with some flash. I taped
a piece of annealed gold wire onto an old mill file. I adjusted and
ran the file through the mill.... and presto! A nice "sawtooth"
pattern that definitely catches the light, is reproducible, and
looks good! note that i did protect the lower roller that was exposed
to the file.
