Nice. Thank you.
For a simple top entrance and minimal time, seems to me that Micheal Bush's concept is simple enough and effective. To keep the hive top level, couldn't one just expand the notch in an inner cover? If you wanted to place it between brood and supers, you would have to route out the middle of the cover.....
I am going with top entrances in the spring and the expanding of the notch is what I am going to attempt. My entrance will be above all boxes; brood and supers.

[QUOTE=ccar2000;880092]I've heard that as a rule of thumb a hive needs three square inches of entrance space. A 3/4" hole would give you about about a half of a square inch opening. I am thinking that on a round opening, circumference is key since the bees will not fly directly into the hole but crawl into it. That said, in my case I run a 3/8 x 3 inch standard entrance opening year round which give me about an inch and a quarter.QUOTE]
