Yesterday and today, I made a couple of mating hives.
The queen breeder said the queens will be ready by Tuesday, so I had to hurry. This year, instead of introducing the virgin queens into hopeless queenless colonies, I'm going to let them get mated first, and then add them to small shook swarms colonies.
The mating hive design I used is based on the
"Celler" mating hive (wooden version
here), whose main deviation is the fact that there are no frames or top-bars, but instead the bees build comb from starter strips attached directly from the roof.
I made a prototype yesterday (power jigsaw only) to get an idea of what would work and what wouldn't. Today I used my table saw and miter saw to make straighter, more accurate cuts. However, my "accurate" cuts are not really accurate... they're just more accurate than they would have been otherwise.
And of course I mess around with glue.
My main problem was that the original Celler mating hive assumes that the bees and the queen are added to the hive at the same time, so there's no hole to put the queen cage into. In the end I opted for adding a ceiling to the hive, and making the queen cage hole in that ceiling.
These mating hives are 20 cm tall on the outside and 14 cm wide on the outside.
