have not seen plastic dronecomb here in Denmark. I have cut out half a foundation plate and then let the bees build the dronecells themself. I have placed those frames as a second from left very uniform, so that it is easy just to lift supers of and pull out the frame with drones, then with a knife cut the dronepart out and put the frame in again. a one minute operation. I have average used 5 hours a hive total included honey harvest, honey handling and honey sale. We estimate handling 500kg honey ourself, the rest goes to honeypackers.
Sorry this is a redo of the message. Drone combs are bought whole like other foundation, and placed in a frame like other foundation. When bees are preparing to Swarm you can let them build the dronewax themself from scrats.
You can vertical devide a frame in three parts and use for swarm control. 1/3 normal foundation, 1/3 nothing and 1/3 drone wax. As long the bees build normal brood wax in the empthy 1/3 the bees will not swarm. When they start to build Drone wax in this they will likely prepare to swarm. the 1/3 with dronewax you just cut out leaving a strip as guide.
be aware that bees always are able to trick you and do what they like to , whatever you think you have under control.
