I have an old copy of Eugene Killion's "Honey in the Comb", and in that book he describes his set-up involving standard Langstroth deeps, with nine frames in the center of the hive and with a 3/8 inch thick follower board at each end.
He talks of how much better it is to pull frames after first removing one of the follower boards. He also describes the necessity in having frames that can be interchanged in different hives when they are cut down for comb honey production, and how, with the follower boards, the nine frames in the hive are all kept at the same widths by the bees.
Anybody ever tried the Killion set-up?
