One of the problems with setting up a horizontal double-queen hive is getting everything level and flush so the queens can’t find little openings where they might leave their own hive and get into the neighboring one. In the original post about this system, Bill Hesbach mentions that he prefers to connect the bottom boards with screws, a system that works even if the ground is slightly uneven.
Laura Colburn of Florence, Texas solved the problem by building a hive stand that provides a solid base for the hives but sits easily on concrete blocks. She said there is still some wiggle room, probably due to variations in box sizes, but she thinks her system is tight enough to work properly.
Another variation on the double-hive stand was created by my husband, Rich. Several years ago, he built some single stands that I really like because they are stable and work well even on lumpy ground. I asked him if he could make one twice as wide, and he did just that.
Being an engineer, he builds things that can withstand earthquakes, floods, volcanic eruptions, winds, and all the other ordinary things we get around here. In the photos below you can see the stand fastened together with carriage bolts and seismic clips. Anything for the bees.
That’s as far as I’ve gotten on my hive—no end covers yet. If anyone else has ideas on double-queen set-ups, let us know.
