MetalMuncher Posted August 19, 2009 Share Posted August 19, 2009 Greeting fellows smiths!!! Been doing lots of lurking, havnt much time for anything. But I want to make myself a small puukko. My questions is exactly how thin do you grind you bevels before tempering? In my past experience, I tempered a scandi, but the bevel was left at about a dimes thickness. I had a really rough time grinding it down to a useable edge. Will the edge be prone to cracking if I ground it down all the way? Or will it hold up. I will be quenching at Curie temp, in some warm motor oil. Most probably will be using an old file or 5160. Tempering at 175 C. for a durable, tough edge. Cheers mates!! Thanks in advance for any help! Michael Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted August 19, 2009 Share Posted August 19, 2009 Usually I leave the bevel the thickness 1-2 mm before hardening and temper immediately after hardening. Of course I have a belt grinder to make cleaning up the edge easy after heat treat. I think you are using the term tempering for several stages of heat treat where we will often break it out into: Normalizing, Hardening, Tempering; to prevent confusion when we are discussing specifics.
