Observation Hive Dimensions

[MatarazzoDesign]

Hello All,

I'm looking for verification on my dimensions. We are designing a 4 Deep Frame Observation Hive for our Science Center. My previous post  (on BeeSource) was focused on the shut-off and how to incorporate that into the design. Now I'm trying to get the OB Hive dimensions set so we can start working out materials. I didn't get many responses from BeeSource, so I thought I might pick the brains of your community.

I used the following sources to get my measurements:

I used 3/8" for bee space between the top and bottom of the frames. The interior spacing between the 1/4" Safety Glass is 1 3/4". I've only got 1/4" between the edge of the deep frame and interior of the hive structure. Is this ok, or will this be a problem for circulation? I added a 4"x1" rounded slot at the bottom of the hive to line up with our exit/entrance chamber below. Based on my dimensions I believe this will work with standard deep frames. Please note, I haven't modeled in ventilation holes or accurately modeled the woodworking joints for the hive.
