Ed Foote:

 YES!!  I agree  with Danny 1000%.
        I can see the utility of modern adhesives in many places on a piano,
 but for the stuff that will eventually be replaced , hot hide glue has a
proven record,  and is easily undone when the need arises.
        Back rail felt,   rebushing keys,  felting the damperheads,
 attaching hammers, and almost every other thing that falls under the
description of "non-durable" should be glued with hot hide glue, (IMHO)


I agree that hot hide glue is wonderful for its removability
features, among other uses, but PVC-E glue also falls under that
category. I've removed a *sloppy* set of plastic naturals that had
been glued on (by a competing piano rebuilder) with PVC-E 2-3 years
ago and reglued them with the same (better alignment and filed them
to shape, though). I had no problems gently peeling the plastic from
the wood, and removing the old glue from both surfaces was as simple
as peeling it away. As for the *real* test of time (50 years or more)
I can't give any ringing endorsements, but other experiences with
PVC-E lend confidence to its staying power... and removability.
