In this particular case, Yamaha didn't use hide glue for damper=
 felts I'm quite sure of. The fastest method I've used was to cut=
 the damper felt leaving the underfelt, and then use wallpaper=
 remover solution with very hot water. I just brush the solution=
 on until the felts are wet. Then leave it on for about 15=
 minutes. I then take the steam approach (slightly damp rag with=
 iron set on cotton) and just steam away for about 5 seconds.=
 This will soften the glue and it will peel off leaving a clean=
 surface ready for new dampers.

Because our modern piano builders choose/chose to use glues that=
 sped up production, but are next to impossible to remove with=
 conventional means, (ie.heat, moisture, etc.), the only way I've=
 found that works is brute force! First, I "peal" the majority of=
 the felt off. Next, I go to my 1"X42" vertical sander and SAND=
 the remaining felt off, down to bare wood. The main problem with=
 this, is that you have to be VERY accurate with this technique,=
 else you'll have head surfaces that are not square with the=
 sides. 
If someone can come up with something less traumatic, I=
 definately would like to know what it is!
