I second the idea of using veg oil(if you don't have commercial quench oil) and stay away from motor oil or tranny fluid. If you are worried about warping, use quenching plates of aluminum. with thin blades, I quench in oil for a count of 5 or 6, then place blade between two pieces of 3/8" or thicker aluminum either in a vise that you can tighten or put weights on it. let it sit between the plates for a minute or two. with thin stock(most of my blades lately are 1/16" thick), this will usually prevent warp. when you quench, go straight down into the oil, point first, and only move the blade up and down.
as Ed said, you are going to have to find the exact way that works best for you.
