I work at a school of music in an area that has relative humidity in the teens for most of the academic year. After completing a job with hide glue just before a vacation, on a whim, I poured some into a small paper cup and left it on my desk. A week later, the sides of the cup had been sucked in (glue stuck to the paper, water evaporated from glue). No big surprise there. What was interesting was that up to NINE MONTHS later I still heard the glue cracking as it (apparently) continued to shrink! (We also have problems with failed glue joints on hammer heads here, but not just from our own hide glue operations....whatever Yamaha uses has also failed on numerous occasions in this environment.) Guess it's time to try Titebond Trim and Molding glue.

After doing institutional work for a few years where I could observe the results of my well-intended labors I noticed a rather startling failure rate, especially on hammers with walnut or mahogany moldings. I would guess that approximately 10% would come loose in a year or two. I don't know if this is due to the brutal humidity conditions or to high use but I switched to Titebond and the problem went away. I recently began using Titebond Trim and Molding Glue and find it to be superior to any other. It dries nearly as hard as the hide glue, is thick enough to form nice glue collars without dripping all over everything and I have yet to find a loose hammer head. Pianotek carries it even though it's not in their catalog yet.

Some prefer hide and some the tite-bond. There is no right or wrong answer as many try to make it. I prefer hide for hammers, but I can understand why others like tite-bond.
