Nice Job Andy, very rewarding isn't it when you get results like these. Don't be araid to push the machine, I'd be inclined to lower the step over on the ballnose so you get a smoother finish, it could be the pictures but it looks a little scolloped which comes from too large a step over. I use between 3 - 5% diameter on cutters 3mm or less and 10% on anything larger. Takes a little longer but get a nice smooth finish.
