  1. Frazer What temperature would you sugest heating the oil to?
  2. Frazer, to answer your question, no the peice did not harden at all & the oil is starting at room temperature (about 67* F), & I am making a hot cut hardie. & BIGGUNDOCTOR, I did try water, again at room temperature. same results: not hard.
  3. I am relatively new to blacksmithing but have gotten far enough to know when something is not getting hard. I use Canola oil as my quenching medium & have succesfully hardend two chisles, & two punches from old coilspring. But I have recently purchased some 4140 & have made some more tools out of it but it seems unable to harden. If anyone has any suggestions I will accept them gratefully.
