Ah, a wooden hinge, you say? Sure, why not, if you can’t find a screw or a latch. But let me tell you, back in the day we’d build a hinge out of oak, notch the ends, and then use beeswax and a good press to keep the joint tight. The glue you’re thinking of—if it’s a modern synthetic resin—it’ll cure too slowly, and the humidity will make it weak. Plus, the squirrels have learned to gnaw through any single layer of glue. I’ve seen a squirrel take a whole board in a single bite! Now, if you really want a “squirrel‑proof” door, you might as well add a hidden latch that triggers a counterweight. Picture a simple lever that, when the squirrel nibbles at the latch, releases a block of wood that swings closed with the force of a spring. Or better yet, use a split‑door hinge that can’t be forced open because the hinge itself expands when the door is forced. You see, a single glued hinge is a bad idea—impractical, yes, but not very clever. And I’d warn you, the adhesive will eventually break down and your door will start to rattle like a faulty clock. Let me show you how to build a proper wood‑to‑wood hinge with a mortise and tenon, and add a tiny pin. That way, when the squirrel tries to pry it, it gets stuck, and the whole thing stays together until you can replace the pin. How does that sound?

First cut a neat rectangular slot in the end of your first board—that’s the mortise. Make it just a hair wider than the tenon you’ll make on the other board. Then, with a chisel and a hammer, trim the sides so it’s clean‑cut. Next, shape a matching rectangular protrusion on the end of the second board—that’s the tenon. Keep the ends slightly tapered so they slide in easily. Insert the tenon into the mortise, test the fit; it should slide in without force but sit firmly. Glue the joint—if you’re using a modern adhesive, let it cure at least 24 hours; an old‑fashioned pine resin works too if you want that nostalgic scent. Finally, drive a wooden pin through the joint—just a straight pin a few millimetres in diameter—so the boards stay together even when a squirrel’s curious paw nudges it. That’s all. Good luck, and keep the pin a tad longer than the mortise to prevent the whole thing from loosening when the door swings.
