Sometimes I want to join to identical pieces of wood that I’ve cut to thicken the project. So let’s say I have 2 or more pieces of freshly-cut thick maple ply. And I want to join them so it’s one piece of super-thick maple ply. I’ve used Gorilla glue, sparingly in the center-ish area and clamped them and returned to find them joined very well, but with glue squirted out the seems. If it’s not clear, I don’t know much about wood. I’m guessing it’s because these pieces are finished wood that’s nearly-perfectly flat so, when smashed together, the glue’s gotta go somewhere. So what’s a better answer? Different glue? Different technique? Both? I’ve thought about laser-scoring the woods before attempting to join them. (It’s like the only thing I recall from working with similar things in art class in grade school.) I haven’t tried that though, but it seems a reasonable technique.
