I've read that canola oil is good for quenching as long as you get the heated work under the surface quickly.

Pros and cons?

I have two revolver hammer faces I want to harden and do not wish to pay the big bucks for true quenching oil.

Quenching oil is a type of mineral oil, and just plain old 10 weight motor oil will work for your needs. Use a plenty in an open top container close to your heat source.

Professional blacksmith here.  Cooking oils work fine for quenching and their fumes are basically non toxic.  I use it for anything with an edge so that there are no poisonous residues.  Whenever quenching in oil use a long set of tongs, the oil will often flame up before your piece is completely submerged.  If you keep it around too long it spoils.

I figure its been a few months and you are probably long done, but just in case....
