I have a full woodworking shop for my other business and use locking a miter joint quite a bit for long columns and stair parts to ease assembly in the field. The tolerances for the lumber thickness are so tight that we plane our stock within an hour or so of actually running them through the shaper. If you let them sit for a day or two (especially in FL humidity) it throws off your entire set up.
Box joints are a strong joint but need to have the end grain protected with a good paint and rabbeted joints are ok for nucs or brood boxes (that you don't move often and don't have 90lbs of honey in them) and are quicker to produce, but still have end grain that needs protection.
"In the first place, we should insist that if the immigrant who comes here in good faith becomes an American and assimilates himself to us, he shall be treated on an exact equality with everyone else, for it is an outrage to discriminate against any such man because of creed, or birthplace, or origin. But this is predicated upon the person's becoming in every facet an American, and nothing but an American...There can be no divided allegiance here. Any man who says he is an American, but something else also, isn't an American at all. We have room for but one flag, the American flag...We have room for but one language here, and that is the English language...And we have room for but one sole loyalty and that is a loyalty to the American people."
Theodore Roosevelt 1907
