I've not had any problems with hide glue failure but for hammer hanging the consistency must be fairly thick. If you can easily "pour" the glue into a cup, it is too thin with too much water and will shrink more than is advisable. I use some urea to keep the glue from gelling up too fast which allows you to make a much thicker consistency. You should use enough urea to allow some time to adjust alignment after assembly. If you are making adjustments to the alignment and you feel a letting go of the joint rather than a smooth turn, it is setting up too fast and you should use a little more urea. It should be thick enough that even a fairly heavy glue collar won't sag or drip. Be sure to apply the glue to both parts! I have tried all the glues, Bolduc, Titebond, Titebond Trim, and I still prefer hide glue. For bushings you will need a much thinner consistency and it should be quite runny.

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.
