Hi John, In reading the portion of your letter that's below did you ever try the metal frame spacers ? How many T.B.H.'s do you have now ? It seems that with proper top bar rotation mites should be kept down quite well. Do you do that and if so is this a sound observation ? Being the top bars rest side by side they can be difficult to align due to bees in crack and propolis build up. Special rack needed to hold frames after they are removed from hive. You can never set a frame down or lean it against the box.
