I'm rather pleased with the way the chess pieces have come out!

The Mastercam/G&M code files for each of the pieces have been finished and tested. I'll have students testing out my lab procedure and finishing up the rest of the aluminum set next week, then I'll probably teach one of my assistants to make them and have him cut the brass set. They are cut from 0.875" round rod stock in either 6061 Aluminum or C360 Brass.

They take more hand finishing than I'd like, since the aluminum likes to chatter around 3.5" from the chuck, but a couple fine grits of sandpaper and some fine and very fine scotch cleaning pads put a nice shine on them.
