| i know what you mean by the tube and the stays are the first to go as i am helping re tube a aveling and barford roller, fine i admit the tubes are 15 years old but in places they have gone from 1/8" thick down to 1/32", and when we cut the tubes out with oxy acytalene we checked as may stay as we could and they are starting to corrode around the firebox rapper.
and thanks for the info about welding boilers, 6" is definatly the next project unless a full size comes along.
