u/Hop-Dizzle-Drizzle

I made this for my nephew when he was born. He's now a toddler, so it inevitably ended up broken. The break is real clean on an existing glue line. I'm planning to clean each side up quick with sandpaper on a flat surface. But I'm stumped on how to clamp it. any tips?

I also wouldn't mind adding a couple small dowels, but alignment seems real tricky in this case.

Material is birch butcher block from home Depot.

Bot sure if he's hearing the neighbor dog, or demonic forces bent on our downfall.
