I've researched all the commercial boxes and it would be nice to keep it to the standards but I'm going in a different direction. I built the 7 frame for a trap box and because I watched a youtube explaining why it's better to use 7 frames. Then Fusion Power gave me a few links that made me question using the smaller boxes and that includes deeps. Now I think I have to go with square Dadent frames 11 1/4 - 13 Modified Dadant frames, rarely seen in the U.S. but very popular in parts of Europe as the Dadant-Blatt frame.
Since I don't have bad habits yet I would rather go with what others have done successfully using different methods and learn along the way. I'm sure I'll make mistakes along the way but you can't fail if you don't try.
Here's the link to his post. There's years of experience and knowledge in these links.
