Re: Converting a TBH into a Long Box Hive?
All of my long hives fit lang or top bars. I have also devised a way to support comb from top bars in which a piece of larger hardware cloth is stapled to the edge of the bar, trimmed, and bent in the manner of a hook, so you can hook the comb onto it.
I have about 1/2 standard langs, and 1/2 long langs. I gave up on the top bars as the bees drew too much comb and the collapsed in the heat with no bottom support. It might work better with a medium sized box, but deeps are too big for unsupported comb in my opinion. These days, I just fill them with foundationless lang frames.
