I was sitting and thinking about how heavy a full ten frame box can get ehen its full of honey. So i was thinking of how to lighten the load some. So i came up with this. Have 1 or 2 bottom brood boxes as 10 frame then make the honey supers 8 frames. We all know the sides will be short and the 10 frame would be open. But if you make some kind of shim that closes off the sides. Or a piece of 3/4 in plywood with a hole cut to fit the 8 frame. Lay the plywood on top of the brood box then the 8 frame on top. I saw that method for nuc boxes used to combine hives. This can be a old idea but i never heard of it. So im wondering if anyone has tried it and how has it worked. Im thinking of doing it to utilize all my boxes. I suppose you could even put a new package / or spit in a ten frame brood box and set nuc size boxes above it for winter warmth when starting late. Theres many box combinations that can be used for whatever situation your are in or want. Just thinking of experimenting with this idea.
