Can anyone here tell me if standard steel key stock can be hardened using the drill press, torch and oil method. I went through my old MH and cannot find reference to 'key stock' material. I'm trying to build a gooseneck style turning tool for use with replaceable tool bits. I'd like to get a fifteen or 20 thousandth case on the tool. Any info on color to heat to, etc, would be greatly appreciated. A definitive 'can't be done' would help too. I don't want the thing to break and damage me or the lathe. I've made a lot of things with steel, but was not too involved with the HT aspect.
Thanks
Mickey
