Hi Les, I've had this work every time except once, and they left the queen behind. I put together my box like this, going up:
Bottom board, metal queen excluder, deep or medium box, frames including a frame of brood, lid. Leave all intact for 4-5 days, then remove queen excluder. The bees can come and go but the queen can't get out the front entrance.
Bummer that the bees left after all that work! :'(
