PVC-E?

[Richard M]

The ivory can probably be pulled off. Or slipping a thin blade under.
Steam might help.  PVC glue is not like elmers white or tight bond that
needs clamping for strength.  Well it needs a little but  not too much.
If  you squeeze out too much its not as strong.   Its more for gluing
incompatible materials like nylon cloth to wooden pneumatics.  I've used
it for regluing ivories on real rough surfaces, when I can't use a waffer.
Works OK for those plastic simulated ivories.
	I'm going to try the suggestion of putting a drop of warm water on the
old but clean waffer.  I've got a keyboard exactly as you describe.
