Does anyone have plans to build Kirk Webster's Feeder Frames? http://www.kirkwebster.com/index.php/slide-show-with-captions shows some pictures, but I don't really get enough of an understanding. http://www.kirkwebster.com/images/stories/kw/14.JPG For example, how does one side access one end of the feeder frame, while the other accesses the other? How is it designed so that the bees and/or queens don't just cross the feeder and battle? How is it designed to make sure no gaps exist on all sides?
