I've been helping Adam out with a veteran's memorial sample. We started this last weekend and I finally got back to it today. I'm currently running another pass on it with a 1/16" ball end mill. It'll be interested to see this process done in aluminum since I usually do this in Corain and you end up being able to see light through it. Aluminum will take on a completely different effect, but it could be interesting. I'll post pics of the completed piece once it comes off the mill.
