Recently, i was perusing the topics on Bee Houses and ran across a video of a Beekeeper who was extracting honey from the hives in his bee house. He used two rotating cylindrical brushes to remove the bees from each individual frame. The bees fell into a chamber underneath which the beekeeper then shook into a bucket that was used to empty them back into the hive.
I lost track of that Video and would be very interested if anyone has come across it or has any information on the rotating brush gizmo that he was using.
