If I knew that, or believed there was even a possibility of that happening, I would never have suggested it. Part of the success of such a modification would be to make changes in the stay design, as they would become a different thing than what was called for in the original design. They would probably want to be larger in diameter than what was originally specified, at least on that exposed end, and then be made of a stronger just as good a heat conducting material such as phosphor bronze.
None of the boilers I've made with extended stub ends, admittedly only a few, have had problems reported to me. I've made boilers with crossed heat sinks . . . center-flue types with solid phos-bronze cross-bars (not acting as stays), which weren't in the least affected by flue heat and steamed very well.
