I finally got my Disc Cutter in!! I ordered copper sheets along with it, so I could practice using it (Sterling Silver sheets are SOOOO expensive!). The shavings on the cutter is called Bur-Lite, which is supposed to keep the punches ability to cut cleanly. Along with the disc cutter I ordered the center-positioning die set, the red pad in the picture, a hole punch (to punch a 1mm hole in the finished product so I can incorporate it into my jewelry), a pair of wire sheers (to cut the copper sheet), bur-lite and a brass 1lb hammer. I'm thinking I should have also ordered some files, but will try to use what I have. The cuts are clean and sharp. It took only a couple of hits with hammer to cut the disc! Quite easy to do, and I the ideas how I could use these are bombarding my brain!! It was a quite expensive order, so I hope it pays for itself in the long run.
