Robbie, I'm certain that you are right. "Hoyt" metal in the context
which I stated does seem to be a highfalutin' term for "tin-plated,"
but I have heard local (Detroit area) pipe organ people refer to the
two-ply sheet metal as "Hoyt" metal on numerous occasions. I looked
the term up in the Organ Supply Industries catalog. Here's what it
Hoyt metal -- two ply, tin coated, 84% lead, 10% tin, 6% antimony
The string seems to have gone in the direction of nonferrous metal
casting. I just thought that Matt Caulfield's original posting might
have been referring to the sheet metal used for pipe making, since he's
such a band organ enthusiast (me too).
[ Now I'm more curious: if indeed it is two sheets of metal,
[ how are the sheets bonded? Why isn't a single sheet of metal
[ formed and tin-plated? -- Robbie
