The first 2, I pressed a little too hard with the tool, and caused them to chip. With a little work, they can probably be salvaged, so I shouldn't have said I wasted them! The 3rd one I didn't think to paint the tube, and I turned it too thin. It was almost clear by the time I finished. I could see the brass tube. On this one, I painted the tube pink, and left a little more "meat" on the blank.
