Well actually I made a trap using the Arapuca trigger mechanism. Instead of making the trap cage from sticks, I used an old plastic bread crate and extended the sides with some planks. I would have made the primitive stick version if I had ready access to some nice straight sticks, but I didn't.
Here is a closer view of the trigger. It consists of four sticks. A short forked stick is propped up against the edge of the cage. Another fairly straight stick is jammed into a step cut in the side of the forked stick. The forked stick wants to rotate into the cage.... but it cant because two light sticks are wedged between the bottom of the forked stick and the back corners of the cage. The knife is a carbon steel Mora... an excellent general purpose tool.
There are quite a few rabbits around where I'm staying, so maybe one might venture under the trap in the next few days.
