There I go, thinking I was original again...
I made mine with all the vac parts in the top so I can use the hive body AND the bottom board. pop the top/vac assembly off, drop the inner cover and lid on. Remove the entrance board and the hive is set. Put the board on the entrance of another empty hive, drop the vac onto it and its ready for the next cutout/swarm..
I have found in trying to perfect this, that I do not get a lot of debris on top of the frames when the Suction is adjusted correctly so that I do not kill bees. Light debris, like leaves may go in, but heavier stuff, wax, sticks etc do not. The six inch chamber above the frames allows the vacuum to dissipate. Everything that goes into the chamber falls on top of the frames, including the bees, and as a bonus, I can carry it with one hand. (empty)
I also use a simple ratchet strap to bind mine together. I am all about simplicity.. after a hard day of sweating, I really appreciate the simplicity of the design. Once I get the bees home, it takes five minutes to remove the vac from the hive, drop the cover on, and unscrew the entrance board. It really saves time and allows me to get to that rum and diet cherry coke that's waiting for me beside my chair, overlooking the pond, in front of my house, with my fishing pole laying beside that.
