Makes me think of the filing cabinet by my desk at work - but perhaps a bit more interesting.
He up ended the bottom slider of frames. Why?

Yes - I didn't notice that before. I have no idea why he did that (the chap in GG's video). Also, the hive he is using isn't quite an AZ hive either because he removes a whole canister of combs, whereas in the AZ the combs are removed individually.

Don't get much chance for internetting these days but as I'm here.... I'd speculate that the upending of the frames is a demonstration of how you can manipulate the bees into drawing the comb in the lower box fully down to the bottom bars, this was a feature of the danzenbaker hive, we've experimented with the idea in some home produced, deep frame, mating nucs and can attest that the principle does work.


There was even a special reversible frame made in 19th century America, the 'Van Deusen Reversible frame':

there's some correspondence in, Gleanings in BeeCulture, June 1889

More recently Wyatt Mangum wrote an excellent article on the subject in the ABJ, May 2010, but unfortunately I don't hve a web link.

Or, there may be a totally different reason for the manipulation as shown in the video!

That's interesting - thanks, Prakel. When you've reversed the comb, do the bees continue to draw out the cells in the original direction - drawing out cells that point down?

(I think I used a wrong word above by talking about a 'canister' of combs. I was probably thinking about a 'cassette' of combs - but that might not be a good word either.)

Hi Kitta, no, they tend to build in the correct orientation with transitionary cells between, however this is of little importance when using foundationless and/or unwired combs; it's more important to get the frames filled with comb, remembering that the reveral isn't permanent.

Another thought which has come to mind overnight is that he may simply have been demonstrating how you can move the honey arc out of the queen's way to encourage upward movement of the brood nest -another aspect of the reversable frame.

If you watch 'More than Honey' the Singer's (Austrian queen producers) appear to use a poly mating nuc with lugless frames which, I'd imagine could be reversable if the operator so wished, but the clip is very brief so this is even more speculation!

I'll now be awol again with no guarantee of internet access, but may return to this thread at a later date

Thanks Prakel. That's two interesting uses of reversing comb - but I'm not tempted to try it out. I'll try and see 'More than Honey' again soon. Enjoy your awol state.
