This is what I have to say about Art's book.  This book is _hands down_
the best and most informative book out there on repairing player pianos.
There are dozens of right (and wrong) methods of servicing players that
Art informs the reader about.  Some methods, like using rubber sealant
for gasket work, are clearly wrong; using larger screws on holes that
were stripped out by smaller screws is wrong as well.

There is a _very_ good reason that Art puts the word "Never" in front
of those procedures that might "seem good" to use, like using a solid
wood piece for the exhauster boards instead of a plywood piece.
Another "Never" is using beeswax for sealant.  There was an article in
2005.04.07 MMDigest in which John Tuttle worked on a Euphona player in
which beeswax had been applied, not only to the gaskets as "sealer",
but also to the _entire_ mechanism, which effectively ruined the player
action.  This is blind ignorance for player actions, on an extreme.

One "Never" that Art doesn't make entirely clear, is that the player
owner should _never_ apply any procedure to the player piano that
"might make it work better", if he has not made _absolutely_ certain
that that particular procedure will actually help the player.

Perhaps the worst thing that could happen is if one obtained a player
piano from a dirty, swampy barn, because they were informed that "it
worked the last time we played it."  Last time it played, might have
been 30 years before the future owner was born.

Don't ever invest a significant amount into a player piano on the basis
that it "looks good."  Get it only if _both_ the player action and piano
action can be depended on and were thoroughly tested prior to the sale,
and worked "perfectly".

But there is no such condition as perfect.
