Les,
When 3Reds and I moved our hives, we took the frames out of our 10 Frame Langstroths and put them in 5 frame Jester plastic nucs for transport purposes. Would you be able to go back to 10 frames, and use these nucs when ever you need to move a hive or pull frames of honey?
It made a big difference on my back once I was able to get away from the idea that I had to move the whole box.
When doing hive inspections, I have an empty 10 frame box on the table to transfer the frames to. I set the empty box on the one that is now full and then start unloading the bottom deep, until I'm through. Once finished, I reverse the order. The bees may be a little confused by all of this when I'm done, but I can still walk upright.
