I've always tjought it sort of amusing when I hear someone say "We'll quench one end of the piece to 'run the heat to the other end' of the piece." This goes against the Law of T'dynamics that says that "heat flows from a warmer to a colder area" (My appologies to Sir Isaac Newton). If you cool an area, the heat should want to run toward the cooler end rather than stay/run to the hotter end.
