I am using wooden frames.I have had hives that glued up everything and when i tried pulling a frame out the bottom board came right off. I have bought my side boards.I make the top and bottom boards. I put four nails in each joint.Two from top and two from sides. I have also went to putting seven wires in a deep frame. I have dropped a five wire frame and a seven wire frame out of the same box and the seven had very little damage done.The five had to be reworked. They both were full of honey.
