Hello Laurence,

I did not make the head, I cleaned of all the damaged areas and had it anodized. Cutting fins can be a pain, but with practice, especially at learning how to shape and sharpen a cutoff tool. it gets easier. Most people grind the tool with WAY too much clearance (the angle from the cutting edge down) and the tool vibrates and dives. You want a very shallow angle so that the tool can only feed solwly and if you feed too fast it will actually stop cutting. I don't have time right now, but later I take a picture of some of my tools so you can see what I mean.
