A project that I am working on:
Area clearing lettering out, starting from the center, 3" in height. I'm using a 1/8" single flute, high strength steel bit at 10,000 rpms, running at 2 inches per minute. It came out nice, but is there tooling that will work to give me a decent bottom finish or techniques to clean up the bottom, removing some of the tooling marks.
Thanks! StickMan
