[pianotech] Type of glue for a Kawai

[Paul T Williams]

Jer,

That's why I like the PVC-E glue.  Although it takes a little longer to 
set, you do have a couple minutes to "play" with the items to line up 
where you want them.  Just a thought...

I've had great luck using contact cement.  You have to be very careful 
lining the felt up because you really only get one chance at getting it 
correct with that stuff so you want to make sure everything is lined up 
correctly before you glue it down.

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?
