Re: 8 frame size question
Yes, Mannlake sells the 14" outside to outside boxes for 8 frame boxes.
You can run a set of follower boards in them that way.
You can divide the box into a double 4 frame nuc by inserting a 3/4" division board.
Or you can just use 8 frames and push them all together into the center. This way when you work them, use the hive tool to push all 8 frames over to one side to give more space to remove that first frame, when not using follower boards. The bees will draw the outter face of the outter combs deeper, giving a heavier thicker frame on the outside postitions.
