I'm not going to blame the tools, but I am going to get some more ultra-fine sandpaper. While I'm fairly sure that I could get excellent results if I wanted to spend a lot more time on the fingerstone work, I find the fineness of the stones I have to be a bit coarse. Fortunately, 3M makes a fine line of extremely fine metallurgical grade abrasives, and I just ordered some to play with.
I also ordered a lathe tool for decorative work, called a radius tool -- it allows you to make spherical and partial spherical turnings, it's basically a tool holder on a pivot.
I know I promised pics, but the light tent, while found, needs repair, and I don't seem to be able to get a good pic without glare without it. Soon, I hope.
I started the rough work on the next pizza wheel, L6(actually 8670M)/O1 damascus with hamon. Given the lessons learned from the first one, it should go faster and, I hope, come out even better. It's smaller (2" dia vs 3.2" dia) which should help, and the pattern welding and hamon should be more visible since I shouldn't have to remove as much "meat" off the edge around the hamon. We'll see how it turns out.
