Quenching Oil

Doug Reynolds

>Just returned from a two-day Plane Making 101 workshop at Gary Rogowski's Northwest Woodworking Studio in Portland, Oregon. We made miniature brass planes used in violin making. Course was taught by Ken Altman who makes bows played all over the world. Blades are of oil hardened O-1 ground flat stock. I understand that I can use virually any oil to quench the blades during the "heat treating" process, even vegetable oil. My question is, is there a preferred quenching oil? I could find none in my Grainger nor J&L Industrial catalog.

>The higher the flash point the better,I`ve used 10W motor oil.I have a friend that swears by peanut oil.You can get quench oil from folks who do commercial heat treating,you may not like the price though.

A word of caution,whatever you use put it in a container that you can cover tightly if it does ignite.Don`t skimp on the amount of oil either.More oil means less chance of ignition.Do NOT stand over the container while quenching either(seems like common sense but...)
