Thread: Optilock Screws

I've found polyurethane glue to be easy to use in cracks and it is very strong. Or epoxy which is a two part mix (and it is better if the two parts are mixed precisely. Mix in some sawdust from the piece of wood being glued or some other wood of the same colour to make a repair almost invisible, however, epoxy does tend to dry darker, so best to test first for colour.
