In Eugene Killion's "Honey in the Comb" he mentions a follower board, which is a frame-like piece of equipment that is placed between the inner walls of a super and the frames. Killion runs his hives with 9 frames sandwitched between two follower boards, which can be easily removed when working the hive, providing room to move that just isn't there in a ten frame hive. The plans for the follower board are included in his book, and a follower board should be easy enough to make up, except that the width of the follower board (3/8 in or 10 mm) is not a standard stock for pine. This is no problem if one has the right tools, specifically a planer to reduce standard stock (3/4 in) to the needed width, but the price of a planer will more than cover the cost of commercially offered follower boards, except I've never seen follower boards offered commercially. Anyone know of a source? TIA! Aaron Morris
