I agree with Deadeye. Thats the way I do it. The poly glue, I use Gorilla, expands a bunch. This fills the voids. I put the glue directly into the hole and let it expand to fill the void. As the glue creaps out of the hole I use a cotton swab to take up the extra glue. The hinge point has some grease on the hinge so it will never have a problem with the poly glue.

This will be stronger and lighter then any thing else you can do using hinge points.

hope this helps
