Reinforcing sharp-key tips with CA , prior to Spurlock sizing caul apllication.

[William R. Monroe]

Yes, Gordon, I've done just that treatment.  Works well, I think, on the 
area around the mortise for the front keypin on sharps and on key button 
areas on pianos made with nice spongy (crap) wood for buttons.  If the 
cracks are large enough, I prefer to use titebond and a feeler gauge for 
getting the glue in.  Many of them are not split like that, so I do use CA 
too.
