I am going to attempt to make a bezel for a ladies watch in stainless. It's basically a ring of steel around 18mm with a recess in the front for the crystal (push fit) and a recess in the back to "snap" onto the case. I am using stainless tubing. My question is, should I machine both internal recesses first and then part off to the inner recess or should I cut into the tube with the parting tool first and then cut the internal recess outwards to meet the outer cut to part it off?
