point me to something that works?

I did it the way Larry says, and looking for the little sweat beads seemed to
work fine. I also used peanut oil, because of the high flashpoint or whatever;
that was also fine. There's enough variability in hardness and temper of my
vintage irons that I basically expect some inconsistency, and I've had no
trouble using my hollows and rounds. YMMV, and good luck!
