I just bought some cedar to build two double five frame medium nucs. Probably would have used pine but it was only about 20 % higher and i dont like painting all that much.I'm using 1x8s. I was thinking of using the full 7 1/4 width of the board for the height of the box. Will that leave too much room at the bottom? If the ends were 7 1/4 x 7 1/4, I could stand them up so the sides wouldn't have to screwed into the end grain. I believe this would be much stronger. Would that make the inside too narrow? If I don't paint them will glue hold up withou the paint to protect it?
