Careful with the caulk. You don't want to run into one of those that emit acetic acid as they cure. You will know they do because a bead will smell of vinegar.
Ammonia-smell caulk OK. Vinegar smell caulk BAD.
Wood glue and other glues that harden would seem to have very little flexibility. However, I'm not sure it needs much, if any, flexibility.&
It doesn't. It only needs to be flexible enough to withstand thermal cycling and TCOE mismatch between the screw and the core material.
nbsp; I've also used wood glue with no issues. I WOULD be leary of using any of those glues that expand as they harden.
Melamine ok. Moisture cured polyurethane (Gorilla, Titebond Purple) bad. Fortunately, the MCPU adhesives usually have a temperature label saying not for use at low temps.
