Hey guys, nothing ventured, nothing gained. Art Buchanan has it right. A common heat source is almost always adequate. I use a propane camp oven and a Taylor oven thermometer that goes up to 600 degrees F. and a flashlight to look into the window as it heats. This is not rocket science ladies and gentlemen. Try it on the common scrap steel you have laying around. This method of hardening steel is discussed at length in Randall Gibson's book Krieghoff Parabellum. Page 51 B. Heat Finishing. Gives the temps and times that the Krieghoff factory used. They suggest 15 min once reaching optimum temp. for strawing, correspondingly longer for darker colors. Like Art says if you don't get it right the first time try try again. Remember a saying from my Airborne LRRP days...Fear is a disabler. Try it you'l like it. Jerry
