@Duane: In my case the burns would be palm prints, as that 300 Watt soldering iron I mentioned, used to rest on a bunsen burner tripod. Two of us working at one bench, it had to happen, my co-worker put the iron the wrong way round, so i got the heating element embossed in my closed hand. Ouch. After nearly 60 years the marks are almost gone, but the memory lingers on.
Sheesh Max, here you go again threatening to make our lawyers' heads explode hosting a soldering competition at a live event. But (and it's a big but) if our readers want, er demand it, I will start looking into it. I'd hate to face your wrath if I didn't deliver.
