Agree with that - there's not much room for fingers. I made a stand-alone 2 Framer once - more correctly called a "wouldn't stand-up alone in even the slightest breeze 2F nuc box". Ended up on the bonfire - wouldn't even consider making another one.2f Dcoats style I felt they ended up a bit tight to work so adding a little width would be good
I am thinking of making a 10 frame box into 4x 2 frame nucs for next year due to the amount of queen problems that I have been having. I think it will be easier than mating nucs or full size (5 frame) nucsI put dividers in an 8-frame box and it became 3 2-frame nucs with space to work. Don't have issues with wind either.
