Anyone here experienced in (homebrewed) Cryo-Treatment of O-1 ??
I shape my wood lathe tools by hand, and then heat treat in a campfire
and quench in used motor oil. I have access to LN2, but wonder if it would make a noticeable improvement of the O-1. I know I will encounter inefficiencies due to Leidenfrost effect, even if I pre-chill the steel to minus 80 C. (Perhaps I can roto-vac to make slush, I'll have to explore that.) Opinions? Do you think my methods are too primitive and hit-or-miss to achieve better sharpness and edge retention on the lathe tool? Am I barking up the wrong tree? Would the little extra hardness gained not be desirable for this application? Pointers? Links? Thanks for taking the trouble to read this mess, -j |
