I use yellow carpenter's glue for most of my glue ups, and have, really, no joint failures. However, I am gluing blocks to the inwales of my canoe, and this will require some gap-filling, no matter now carefully I match the block to the inwale. So, I am thinking about Gorilla Glue, or similar. When this expands, will it have the strength to hold the seats up? The strain will be a shear strain, as the force on the joint will be straight downwards, and any gaps will probably be on the order of 1/32" or less. I intend to reinforce it with a pair of #14, 2" screws as well, but I don't want the seat suddenly plunging to the bottom of the canoe when I am half a km out on Lake Ontario. Will the Gorilla Glue do the job, or something else, or something else altogether?
