There, it's ready to use. I've also used micro polishing paper, cut into strips, with the split mandrel to get a good polish on metal as well.
I think next, I will be cutting circles and adding them to a screw top mandrel and see how that works.
I'm always excited to figure out a different way to use the items I already have, without buying new stuff. Although, to be honest, buying the new stuff is super fun, too!
