I worked on an old player upright last night. It was a 1907 variety, but someone in California had rebuilt it very well. Why? Who knows? But it was in very good shape, and close to pitch. All the ivory keytops, the squares, were coming off. about 15 had been off for quite some time, but the customer had saved them and gave them to me to glue back on. I also gave a tug at all the rest that had not come off yet and found that most of them were loose. I got out my trusty PVC-E glue and proceeded to glue them all back on. My big mistake? The glue paints on very white and pretty, and I took it for granted that it would dry that way and would hide the finger prints and other imperfections that were on the top of the keys that had not had a keytop on for a while. When I started taking the rubber bands off and reinstalling the keys, I got a big surprise. PVC-E glue dries perfectly clear, leaving all imperfections glaring through the keytop which were all very well glued on now. The job looks terrible, even though there are now keytops installed which I'm sure feel very much better than the key did without the ivory. Even so, it is very obvious which keys had been bare for a while. Should have I used another white glue, such as Titebond? I have always stayed away from the regular white glues for keytops. Anyway, a word to the wise. Don't do what I did. If you are going to use PVC-E glue for ivory keytops, make sure the keytop surface is WHITE before gluing. Lesson learned. Richard Richard You missed a perfect oppurtunity to use hot hide with glue whiting which would have give an invisible repair. This is how they were orginally glued on & any residual glue on the keys or ivory would have been nicely reactivated when th hot hide went on.this process does require the brass plates & clamps but in my mind is the best of repairs.To undo what has happened now may not be possible but heating with a white wwet linen to get the glue undone may work. Then scrape & clean & see what happens Dale ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
