Keytop Adhesives

[David ilvedson]

I also use the 3M spray glues.  I use both the #77 and the high 
strength #90.  I found out that the #90 will etch the keytop if 
it gets on it so I use the #77 for spraying the bottom of the 
keytop and the #90 for the key.  I use an old box into which the 
overspray goes for the keys and I line up two octaves of keytops 
B to C on the bench w/paper and spray them all at once.  If 
after spraying I immediately move the keytops to a clean piece 
of paper they won't stick to whats under them when I install to 
keys.  Hand pressure fitted and then into a table clamp for a 
few seconds.  I use keytops from Schaff/Pianotek with fronts.  I 
just saw a set of keytops from Yvonne Ashmore in the Sacramento 
Area and she does a great job...they look like Kluge...they even 
have the keytop end (under the fallboard) beveled.  Very nice!
