I just caught my first swarm two days ago (okay, really a beekeeping friend caught it for me - I just watched with my running shoes on). I'm wondering if most people use 9 or 10 frames in their hives. I hear of spacing tools and such - and even 10 frames fit with room to spare. Is one approach better than the other? Is this a new fad, or is their supporting research? If some exact spacing is best, why aren't the frame sides simply manufactured wider? Is this a case where manufacturers sell some new tool rather than fix the problem? I've been building my own frames - time consuming, but fun - and I could easily make my frames wider. Should I? By the way, the frame plans on this site are great!
