I have been mulling over smaller frames. For example making frames to fit across a Lang box instead long ways. If you forget the economics of extracting the most amount of honey from a hive and looking at convenience for amateur beekeepers and age challenged ones it makes sense, The original Langstroth hive
from this picture seems to have very small frames in sets of three.
Another alternative would be to have a runner down the middle of a Lang longwise and have small frames on either side
. Rough calculations on this would require two rows of 11 frames about 196 mm(7 3/4") wide perhaps a full or 2 X1/2 depth boxs.
I saw similar to this in the Utah Hive site. The eco Utah Hive also an alternative.
I looking at keeping the external size of an 8 frame Lang so the flowFlow box fits.
Any comments or suggestion welcome. Building it from scratch in wood would not pose a problem.
