In case anyone ever had any doubts as to why a lap-seam, riveted boiler is a bad idea, check out:

I'm no steam mechanic, but now I understand.

I went on the site, joined the forum and stated that the metallurgy of 1900 was not as good as it is now. Got told in no uncertain terms that it was better back then. I'm sure the Titanic passengers will be glad to hear that. I forgot that I was posting to people who believe technology stopped when the cast engine frame was invented.
But speaking of good boilers, what do modern steam engines (oxymoron?) use for lagging? If I ever get to build the Little Engines 4-4-2 I want, I'm thinking about using knitted Kevlar wrapped around the boiler. I can don a knitted Kevlar glove then cover that with a Playtex type rubber glove and stick my hand in 150 degree water. The only thing that makes me take it out is boredom or seeing the super walking about outside our NDT shop.
