How do you make the carved out handles in a bee box? If you know how the manufacturer does it or how you can do it at home, I would appreciate the info. The concave handles cut in the sides of the manufactured boxes have me stumped.

Carl-I have purchased hive components that have hand holds that were made by simply lowering the pices onto a dado blade about 3/4 inch wide. It creates a recessed handle also but without the taper.
It was done with one stacked set of blades that is elevated above the surface of the table by maybe a half inch. Each side is lowerd onto the blade just once and then lifted right back off so that it creates one hand hold.Carl-
I like that idea of using a dato blade. Did they do several side by side or just one that was “finger width”? Other than our first setup that I bought as a pattern, I have built all of our boxes myself. I do like having recessed handles, but it would be nice to have an easier way to make them than what I do now.
