I’m building some shelf-ettes to put into an exiting Ikea Kallax unit so that I can “double-stack” my CDs on top of each other to make more efficient use of the space and store twice as many CDs. I’m planning on making them out of 1/4” (6mm) baltic birch ply because I want to waste as little space as possible with the structure of the insert. What I can’t figure out is how to join 6mm ply to itself. It’s just so thin! I can’t Domino it and my smallest pin nailer is still 18ga (which I’m afraid will blow out the ply). I’m not wild about relying on gluing ply end/side grain to face veneer ether.
How do you guys join stuff this thin for a quick-n-dirty project?
