[pianotech] Type of glue for a Kawai

[David Weiss]

While we're on the subject:

I'm replacing the felt on a muffler rail on an upright.  (Mouse damage.)  What's the best glue for gluing the felt to the metal rail?

Phil,

As you found, wood glue does not adhere well to plastics.  Common choices are PVC-E, PVC-A, C/A glue (needs to be very thick C/A to prevent soaking into the felt too much), or epoxy.

The PVC glues are good to carry because they also work well for minor wood repairs in many cases.

I replaced a butt-felt on a Kawai upright piano that had fallen off somewhere and the jack was making noise.  The piano was the new carbon fiber (black plastic) type of action.  I used some white glue I had in 
my case and when it got tacky I reassemble it.   Worked fine!  Played it 
a hundred times.  Day later I get a call-back, the jack is clanking again.  Did I use the wrong type of glue for this material?  CA perhaps?
