I'm am building my hive boxes from rough-cut pine. I bought and assembled my frames. The deep frames consistently measure 9-1/8".
I am trying to determine the width to cut the boards for my deep boxes. The BeeSource plan indicates 9-5/8". The frame rest is 5/8" deep.
The ends of the top bar are about 7/16" thick.
When doing the math, this gives me a space of about 3/16" from the top of the top bar to the top of the box. And, the space from the bottom of the bottom bar to the bottom of the box is about 5/16".
This gives a bee space between frames of 1/2"...too much.
I was under the impression that the bottom of the bottom frame should be flush with the bottom of the box, but I could be totally wrong.
Common sense tells me to just cut the width of the hive body between 9-3/8" to 9-1/2" to get the desired bee space of 1/4" to 3/8".
