I'm wondering which glue I should use for the wings of my bass. (I have a build thread here). The wings are to be made of two walnut board each, which I will need to laminate together to make the wings the right thickness. I was originally going to use original Titebond, but I remembered the woodshop teacher had a bottle of Gorilla Glue at school. Would it be better to laminate two boards together with polyurethane glue? I've read some glue threads before but I haven't seen this situation in them. I know that polyurethane glue will expand, and that it won't cause boards to warp since there's no water in it. I don't know how much warping the Titebond would cause on my boards, but I heard it can puddle between two large areas. Also, I was thinking that maybe the Gorilla Glue would make a glue line between the two boards. I don't feel that would really be a bad thing, since I kind of wanted some kind of separator between the two pieces.
