I don't think I need to blacken it since this is transmission mode stuff. Thanks for the reminder. I have some brass door kick plate I think, but I tried to engrave some name plates and found that no two sheets of it machine the same. The first one did a beautiful job & sold the name plate idea, but the next sheet was a little gummy & threw up ridges. And its that stuff I have half a sheet of. Good idea. Thanks again.
