In this video, I talk about quenching when heat treating ferrous metals. More specifically, I answer John's question about the difference between how blacksmiths and toolmakers quench their parts. Certain very important safe practices are also presented. This video is part of a free online machine shop course accessible to everyone on my webpage THATLAZYMACHINIST.COM . No sign up, no subscription and no hassle, it's all free and always will be. As for all of my machine shop videos, this video is specifically produced for novice machinists. Thanks for understanding that I am a professional toolmaker and teacher but I am not a professional video producer (and it shows). I produce these videos for fun as a little retirement project that lets me give back a little of what was passed on to me by so many amazing trades people, most of whom, sadly, are no longer with us.
