Various wood glues tried and all work fine if properly clamped. I wanted to find the glue that Fantail cricket use in their repair videos on Youtube. It is clear and slightly brown coloured. I think it might be Gorilla Glue. Has anyone else tried this? It seems to have worked well on a few major repairs I did recently. You have to clamp the repair and then the glue expands, with any excess drying as a yellow foam. Didn't leave such an unsightly dark line along the repaired crack, which is good, but quite difficult to remove the excess.
