Who has a good design for queen bank frames? I built a couple 2 years back and have been frustrated using them. I used a deep frame with two rows for cell storage for the plastic hair roller style cages. My design used hardware cloth to form sides. The problems with my design was the the roller cages would easily tip over and sometimes the cell plug would fall out letting the virgin queen escape. I need to redesign mine this winter and looking for successful designs - pictures would be great. Thanks
