I've used thin super glue, and I think it is too hard.The margin of error for easing the keys is very small: the tiniest amount of looseness can make them noisy. That's my concern with hide glue as well - it's almost glass hard when it cures. Elmer's glue remains slightly more flexible than yellow wood glue when it dries, so I think that's why it is appropriate in this application. Plus it's non-toxic! Bill Smith (who made the Golden Hammer Award for many years) presented a class on glues several years ago. He emphasized that Elmer's glue is "good glue". He put together some small blocks of wood, and then put them in a baggie with some water for a day. You could see that the glue line had become "milky" but nobody was able to pull them apart. -- Ryan Sowers, RPT Puget Sound Chapter Olympia, WA www.pianova.net -------------- next part -------------- An HTML attachment was scrubbed...
