Just for the heck of it, I'm going to try turning the irons upside
down and placing a black-anodized 80486 low-profile heat sink along
with some silcon heatsink compound in the center of their "hot sides"
to try and get a better idea of their _actual_ temperatures without
having it so skewed by emissivity error.  If I don't reach 392F there,
I'll move the heatsink to the hottest portion of the iron(s) and try
again.
