Building crab traps

I have some plans on building a simple crab trap and will post images and catch results when they are available.
Tomorrow will be going to the Bogue Inlet Pier and will bring a cast trap for blue claws. I never knew you could catch blue claw crabs in the ocean until last year. A fellow fisherman was doing quite well with a buttryfly style trap. Later... I came back armed with my own and did OK myself.
