How it works?
Firstly it looks like a spaceship because the pic was taken in mid september and there is a gallon bucket feeder inside. The right hand side of the hive is a queen right strong colony, able to be supered if required as its national size. In between the two hives is a vertical q/excluder, come queen rearing time the broodbox is re-arranged, a frame of food and pollen, frame of emerging brood and a frame of five day old larvae are moved with bees, (not queen) to left hand box, and the cell bar frame is put in for the bees to cluster. The main colony is then moved to the far right of the main chamber, moving any frames of food and new frames to the left of the box, this makes a large enough space for the nuc to be q/less. the following day the cupkit is removed from the queen mother hive and the cell bar from the nuc. The normal transfer of larvae is carried out in a warm moist atmosphere and the cell bar re fitted in the nuc, the nuc is then fed heavily with honey saved from the same colony and pollen. Fouteen days from trapping the queen in the cupkit cage all q/cells are caged and moved to mini nucs, incubator or nuclei made up two days previous and kept in a cool dark place. The rest as they say is up to mother nature or II if the timing is right (weekend). I hope this reads o/k it works well enough for me to have made a second hive of the same type. The concept comes from a book by Gilles Fert on raising queens, he only uses the hive as a horizontal finisher.
Please ask if you have got lost and I will endeavour to help, the whole base unit is 14x12 frames, the nuc is empty in winter.
