I'm going to try and raise queens by taking a frame of eggs in new comb, eliminating surrounding cells similar to Jorn's description, and then laying the comb flat above a strong, newly (less than a week, probably just a day or two) queenless colony for them to build the cells. You have to put blocks of wood or something between the top bars and the donor comb so that there's space for the girls to build and move around.
The idea is, the bees will draw out queen cells straight down from the donor comb.
Then, carry on with putting capped queen cells in your mating nucs (like the boxes on Michael's page, or standard nucs).
I'll probably also try the Jay Smith method, which just involves those extra steps of cutting the comb into a strip and waxing to a top bar. Either way, I'm going to adhere to Jay's method of feeding the cell building colony (that feeds and caps the cell) honey and real pollen, rather than syrup/substitute, if they need feeding at all at that point in the season.
