I'm looking to add slatted racks to my hives....I would prefer to build them....anyone have a good plan for one (with racks running parallel with frames). Any commercial ones you really like? Any combo rack with screen bottom? Since I am going to probably build mine, I can do about anything, especially if it is an improvement to existing ones available. Is there an advantage to having them seperate?

Do they fit inside the bottom board or on top like another box? I've been trying to picture how they close off some of the front entrance I've read about.

Thanks, Jim
