Making Small Tools-Part II

>Good Morning All,

Well I've got my tool making supplies and I'm headed for the shop. I discovered though that I bought Air Hardened drill rod. What I'm attempting to do is make a few gooseneck scraping tools out of some of it. Like the small Sorby ornament tools. No bits attached just grind the drill rod to be used as the scraper, then bend the gooseneck into it . My question is....since this is air hardened ...does this mean that after heating it to red hot and bending the gooseneck that I just let it air cool....no oil or water quenching? And refresh my memory....that process, the quenching or air cooling....is called tempering?....or hardening? Or are those one in the same?

As always....thank you very much!

Jennifer
