Those of you who have built your own live traps, could you please explain them? Directions? Mainly I'm interested in what materials you used and how it works together. I think I'm gonna have to re-engineer the trip plate and trap door on my dog trap. I want to move the trip plate further into the trap (so the dog is ALL the way inside when his front paws hit it) which seems easy enough, and I need the door to snap down tighter/faster and be less-prone to being pushed open from the inside. Need help/ideas for the door part. Basically the one that came on it is too "flexible" --- my raccoon traps have a solid metal door that is pretty darn sturdy, but this one came with a door made of essentially hardware cloth type wire and it sucks!
