I use a Metcal which is a 40 Watt iron very well controlled but when

You're not kidding. My largest iron is 40W/80W switchable. 40W won't
touch it and I'm not risking 80W! The biggest problem seems to be the cap
case - a long 1" dia aluminium tube with 3 tags at the bottom going
straight to PCB grounds. It's acting like a very effective heat sink.
Going to have to trash the caps from above.
