Hello Ted !
 
It's a work, ok ! but it's easier when YOUR MATERIAL IS ADAPTED.  I
earlier described the building frame of the German PASCHKE.  All my
deep brood supers (Dadant 12 frames) are equiped with a 13th frame
(about British Standard 21x36 cm) which utility was first to provide a
lot of selected drones for our mating place and instrumental
insemination. To remove them from the production hive with 2 to 4
supers, you must only open the back door of the hive, a bit of smoke
and replace the full frame by an empty one (time (not waste:) only one
minute each 2-3 weeks).
