Jeff, I'm a toolmaker & I do it like this:
Cut a piece of wooden dowel & chuck it up in a drill press. Take some rubbing compound & apply it to the dowel (just dip it in) turn the drill press on low-medium speed 100-200 rpms will work. hold the part on the table with your fingers (CAREFUL!) Bring the dowel down onto the part, not too hard. Move the part a little, press it again. Do this in any pattern you want, with a little experimenting & practice, you can make some cool designs!
have fun!
