I don't understand why people need to over complicate a very simple manipulation. A straight demarree is simple. Everything else you
can do is just window dressing, not totally neccessary
you separate the queen from the brood by taking all the brood out of the brood box and putting it (as George Demarree wrote) in the topmost box above the queen excluder (In British parlance that means in an extra brood box above the supers) you then leave the queen in the bottom with foundation and/or as much drawn comb as you can spare.
you then go in a week later and tear down all the QC's (as it is a supersedure reaction from the bees there won't be many if any) after seven days the bees won't have larvae to make any more QC's from so you don't really need to do much more up there. If you want to use any of the QC's produced to make increase you have a choice of harvesting them fot mating nucs, taking a few frames out to make a nuc or splitting it into two or thee nucs thus taking down the top box.
The only reason you need to go in to the bottom for quite a long while is just a quick status check to makee sure everything is OK.
I don't see the need to continually over analyse a method that's worked well for a century and a half then reinvent the wheel - only a square one.
If you want to roll the demarree, you can but it's not compulsory, it's a new thing that some of us played with a few years ago, especially handy if you haven't much drawn comb and the bees are slow drawing fresh stuff. all the other stuff is just trimmings and all set out in the sticky
