Hey guys, I have a new question...I am using a two-brick propane forge for heat treating and Canola oil for my quench. I would prefer to be a bit more "high speed" but this is what I have to work with at the present time. So, my first few knives were successfully heat treated with this method, but my finished product has black baked in scale all over it. I essentially heat treat (01 tool steel) to just past non-magnetic, then immediately dunk it in the canola oil and hold it there until the smoke clears....then temper at 400 deg for two hours...is this process right? Should I be cleaning the blade after heat treat and before tempering? Would an anti-scale compound work in my setup? I can and have been sanding the mess off, but would love to hear of a different way. By the way, I am just a few days away from having my new (old) Wilkin Square wheel up and running. Keep in mind, I am extremely new to this hobby and still getting my feet wet.
Thanks for any help you can offer!
