Beekeeper Jon built a semi-automated decapper to help with the honey harvest. To get the benefit of the decapper you need to use 8 or 9 frames in a 10 frame honey super. If the bees cooperate and built thicker combs then decapping is a breeze. I had used 9 frames in my supers and the bees did not always build the extra thick comb. At any rate it took 1 1/2 days to do my honey harvest last year. With approximately the same number of supers we were able to decap and extract the honey in only 1 day. There was still a fair amount of hand decapping with the electric knife, so I think I may try 8 frames in some supers next year.
