Hide glue can be tricky to get just right. The bridge on my first guitar started lifting after a few months thanks to old hide glue. If you’re going to use it, I’ve found it’s best to make it fresh at time of use and don’t reuse old stuff that’s been sitting around for a few days.
It could also be that you needed to spread your clamping forces out more evenly. I use cauls that span the entire bridge and wings, but are slightly undersized to allow for cleanup.
Additionally, I find that on oily woods like rosewood you may need to rough up the glue surface with low grit sandpaper to achieve better mechanical adhesion as the oils may prevent glue from fully penetrating.
Regardless, when do we get to hear a demonstration? 😉
