This is my take on an OB Hive..
Three frames per box, and I have one box left to make for a total of seven available for 21 frames..
The frame is designed with a raised rear panel that I can attach the clips and latches from one of the front windows of the house directly to this frame. I can set the frame into place, pivot it into the latches, and then snap the lock down inside to pull it firmly against the seal.
From there, I can install the bees, and add boxes just like I would a normal hive. The rear of these boxes are actually OPEN to slide against the glass. (Which I still have to go get cut.)
I have a piece of 1/4 Luan cut to the same size as the screen from the window that I can simply slide into the screen slot to block the light most of the time.
I am not sure what will happen with the glass side of these boxes.. I am fairly certain the bees will propolis the wood to the glass, but having them OUTSIDE and removable means I can clean the glass each time I manage them.. and if I get tired of managing them I can always drop them directly into a standard hive OR.. just leave the piece of Luan in the window
Also not sure how much the warmth from the window will affect them. With the Luan in place it should limit the heat transfer somewhat..
I will be having glass installed this week, then I can mount it in the window. After that, just wait on a split or cut out to fill it.
I do look forward to being able to pop the luan in the morning and have a seat with my coffee to see how well they are progressing.
If you see an issue or problem, please let me know. It will be easier to fix now than after the bees are installed!
