Re: need ideas on how to attach removable bottoms on 5 frame nucs?
Mike, steal an idea from Chuck Kutik. Screw a drywall screw in the front and the back of the nuc box. Do tghe same to the bottom board. Screw two plywood clips to the rail of the bottom board along one side, which will help keep the box from sliding around once you have wired the bottom to the box w/ concrete form board wires from your builders supply.
All royaltys go to Chuck.
