The rounded grooves are made by drilling through the piece and then milling down to the center of the hole. It's a simple method and doesn't require any exotic tools, but it limits me to straight grooves. I would need a rotary table to make a cut like what you're describing, and I don't have one. On second thought, this might be a very good excuse to buy a rotary table.
