I went the same route with working the Elmers yellow glue down between the seperated plys and clamping togerther for a couple of days. Gorilla glue seems too stiff to get very far down the cracks. And then there's the problem of the glue foaming out and sticking everything together. Just as an aside, I went to the local hardwoods store for some lumber and veneer plywood the replace the cabinet for the folding table and bolster at the front gaucho. A 4X8 sheet of 1/4 in. ash veneer plywood runs $70 so a repair is always an option.
Good luck, Tom.
