Dadant & Mann Lake's deep hive boxes measure 9 5/8" & Kelly's are 9 13/16". a remodeler I know just gave me enough 1"x10" boards to build 30 deep hives & more are coming. this lumber is from the 50's & unlike todays 1"x10" boards that measure from 9" to 9 1/4" these measure 9 1/2" to 9 9/16". will that 1/16" to 1/8" difference in bee space be a problem? I could make the rabbet cut where the frames rest not quite so deep or I can laminate 1/4" to 1/2" to the boards & mill them to the proper size.
a few boards are cupped so i'm ripping them down to use for spacer rims, the vertical sides of outer covers, etc.
