Ok - so as you know, before Xmas I set about converting some unused Warre boxes into a form which would take our standard 'British National' deep frames - maintaining exactly the same hive volume and comb area as the framed-hive championed by Emile Warre in the 5th Edition of his book 'Beekeeping for All' - the only difference being that his boxes contained 9 frames to maintain a square footprint, whereas mine contain 8, and are oblong.
These four hives are intended to be run largely on a 'leave-alone' basis, and so a decision was made to fit Slatted-Rack floors to the hives with OMF's below, to be left permanently open - the idea being that the OMF and Slats should provide sufficient attenuation of any inclement winds, whilst at the same time assuring adequate ventilation.
This is the state of play, as at yesterday. These are two of the four bases, with OMF's recycled from pre-existing Warre hives:
With Slatted-Racks over:
And with a box on top - the yellow boxes having 25mm walls, all others 38mm:
And from here it's just a case of onwards and upwards - with 3 boxes per stack (that's 24 deep frames) and a conventional Crown Board and Telescopic Roof - the latter which are still to be made, but it looks like these four hives will successfully meet the 'on-line by the 1st of May' deadline which I'd set before Xmas.
FWIW, the two other hives (not shown) have boxes painted Blue, and Green - my attempt at making the beekeeping yard that little bit brighter ...
