I remember my uncle complaining about those »modern« bee-boxes that were being sold in Germany in the 1970's: Walls too thin, not enough ventilation and a whole other lot of reasons why they were a pile of junk in his opinion.
He made all his bee-homes - yes he called them
bee-homes - he made them all himself. Being a greatly skilled woodworker and having all the necessary equipment - and a good source of wood - he built everything himself.
He used only beech-wood for the exterior of his boxes because (as he explained) though beech wood is softer and less weather-resistant it contains a lot of air and will keep the bees warm during the winter. The walls of his bee-homes were five centimeters (almost 2") thick and lifting a box full of honey frames was a two person job (that's where i came in

) And i remember his bee-homes had a deep bottoms and tops that he would fill up with wood shavings from his own workshop. Deep frames, maybe not for the scorpions but to keep the bees warm in the winter - in the 70's the winters in the
Lüneburg Heath were bitter cold, like the today's winters in the Dakotas or Wisconsin. And he would submerge all parts of the hives in hot wax to protect them from the elements. No paint on those boxes!
