I am planning to construct some medium hive boxes this winter and was considering making frame groves at the top and at the bottom of each box. On my older boxes the lip often breaks after some use, I figured I could get more use out of the box by doing that, cause I could just flip the box over and start using it again.
Also, we have $.5/ft cedar available locally. Is cedar a good material for box construction? I find cedar to be kind of a softer wood that easily splits with screwing w/o predrilling.
