Cryo-Tempering

["Bennett Moe" <bmoe@domain.elided>]

I saw a show on cryo-tempering a while ago. It looked like it was an
ideal way of making things last nearly forever. If remember right, they
did do some engine parts, but can't remember what. The item I remember
most was a trumpet they did. They did not disassemble it when they froze
it and the valves had no problems (though the tolerances are not nearly
as tight as on an engine). It did have a noticeably different (better,
clearer) sound after. Pretty cool. Are there places out there that
actually do this for the public? Do they make a vat big enough for a
R-110 ;-)
