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.

Just bee cents.
