I had some concerns when I read the article about adding PVC-E to parts
of the piano action.  I had a real hard time believing that Art Reblitz
suggested this in his book.  I went through both of his books on
rebuilding this morning and couldn't find anything in them about this
procedure.  As a matter of fact he did mention that you would never use
this product on wood.  He mentions one useful hint (page 110) in his
piano rebuilding book: you can use a bit of PVC-E to silence clicks in
old bridle straps.

There is no mention of using it around capstans.  If I have a very
loose capstan, the key is drilled out and a dowel inserted and then
re-drilled.  If I have some that are slightly looser than I want, I put
some tuning pin tightener (Pin-Tite) in the wood.  But usually they are
so tight that I have to use a tool to turn them.  Just playing them will
not loosen them up.  But playing the piano does cause the felt to
compact and therefore lost motion occurs.

Anyway,  I would like to know on what page Reblitz writes about using
PVC-E for piano actions and leather nuts.
