Talon Tex Overland Posted January 24, 2011 Posted January 24, 2011 OK i know this is a stupid question but my forge is broke and im desperate lol i need to know if it is possible to use an oxy-acetaline cutting torch and tap magic cutting oil to heat treat a small knife made out of 5160 Quote
Thomas Dean Posted January 24, 2011 Posted January 24, 2011 You can draw temp on a knife by heating a larger piece of steel, placing it on the back of the blade and watching the colors run then quench...but then I don't do blades...wait for a REAL bladesmith's answer. Why take a chance of messing it up, take the time to fix the forge and then finish your blade. You will most likely be glad you did... Quote
basher Posted January 24, 2011 Posted January 24, 2011 you can certainly get good results with an oxy torch watch out for overheating . I would get yourself some canola oil as this works well and is cheap . good luck Quote
ThomasPowers Posted January 24, 2011 Posted January 24, 2011 For a small blade a torch is OK---just don't use the high pressure O2! It helps to have a couple of soft firebrick to help hold the heat as you heat up the blade. Quench in *warm* vegetable oil NOT tapmagic (note that cutting oils are often sulfurized and sulfur is something you want to stay OUT of a blade!) Draw temper as you usually do---I usually do a base temper a couple of times in the kitchen oven---where use of vegetable oil for quenching instead of used motor oil or other nasty stuff can save your life! Then I draw the back/spine of a blade further back with tempering tongs or a propane torch. Quote
