Hi John. Well, this was my point : hot hide glue does the job pretty well, even in our humid climates. But will the cold hide glue do ? May I ask Terry and Dale who use it with great satisfaction what kind of climate their instruments are in ? Following the tech at Franklin, the liquid hide glue would soften at 60 % humidity. Is this a concern in a piano where the board is firmly pressed on the rim by the plate ? Ah, and a far more stupid question : on the bottles of liquid hide glue, they print a date. On mines it says "exp : 24/10/07". Does this mean the glue was EXPedited on October 2007, or that the glue EXPires on that date ? (Or was it designed to EXPlose, which apparently it didn't ?) Best regards. Stéphane Collin. I had an old 1880 Schiedmayer (J&P), assembled with good hide glue of course, that I left outside in the English weather for over three years. It refused to disintegrate or go much out of tune and the brass-wound bass strings sounded fine all the way to the bonfire. The humidity here as I write is 94% and will often reach 99%. We're lucky to get 75% even in the summer. Our pianos do not fall apart!
