I am sure I am not telling you anything you don't already know here but,it is the superior cryogenic steel he is using and your using a carbon steel. There is a whole lot of new technology in steel making since carbon steel was the new kid on the block. I have made a couple since getting my mill and they cut good but I am not happy with the end mill I am using, the bottom is flat and I want to have it round. Need some type of bull nosed end mill for this but don't see any in the Enco catalog.
going to stand the rod up vertically and drill a hole in the rod and then lay flat and mill one after the holidays to see how this works. Far as sharpening I sharpen mine even when cutting good to see how it keeps an edge and am disappointed. My hardening of the rod is not good enough . Again John, that is a great job on the doll. Did you make the clothes too? Have a Happy Holiday. Mitch
