I've had the same thought many times. I have resisted. Standardization is a wonderful thing.
I agree with both of you regarding standardization...it works.
I haven't done the math but I'm curious...if you build your own hives to the standard dimensions, do you find that you end up with much waste materials? Or do the "leftovers" from the hive bodies get used up in the frames? From what I read on the various boards, my impression of beeks is that on the whole, they are a frugal lot. I know I am...the thought of trashcanning perfectly good materials in the name of standardization makes the hair on the back of my neck stand on end
...yeah, like that.
But other than the standardization issue, is there a "bee" issue? As long as I maintained proper spacing, would any of this cause the bees a problem?
